These differ in terms of the number of phases (number of poles), max. rated through-current, maximum voltage for equipment Um, tap selector size and basic connection diagram (see Figure 25). The name of a particular on-load tap-changer model must therefore also include these features, hence ensuring an unmistakable and non-interchangeable on-load tap-changer designation. Figure 25 On-load tap-changer designations © Maschinenfabrik Reinhausen 2012 EN inquiry_orderspecifications 41 4 On-load tap-changers (VACUTAP®, OILTAP®) 4.1.2 Number of steps and basic connection diagram The tap selector can be adapted to the number of steps required and the tap winding circuit. The corresponding basic connection diagrams differ in terms of tap selector division (10...18), number of operating positions, number of mid-positions and change-over selector version. The basic connection diagram is named as per Figure 26. The adjustment position is the position in which the on-load tap-changer is supplied. The on-load tap-changer must be in the adjustment position during maintenance work (removal or fitting of on-load tap-changer insert). Please refer to the respective operating/maintenance instructions for more details. The adjustment position is explicitly stated in each of the on-load tap-changer's detailed connection diagrams. The mid-position is the position in which the "K" contact is switched for the reversing change-over selector or coarse tapping model. The mid-position is also generally the adjustment position (see detailed connection diagram for on-load tap-changer). 1 mid-position: With 1 mid-position, there are no positions with the same voltage either upstream or downstream of the "K" contact. 3 mid-positions: With 3 mid-positions, there is no change in voltage upstream and downstream of the "K" contact. Note: Bridged contacts are not considered the mid-position Figure 26 42 Number of steps and basic connection diagram inquiry_orderspecifications EN © Maschinenfabrik Reinhausen 2012 4 On-load tap-changers (VACUTAP®, OILTAP®) 4.2 Operating positions (contact designations/position designations) Figure 27 Operating positions 4.2.1 Designation of on-load tap-changer operating positions Here you define the position designation of the max. effective number of turns, the min. effective number of turns and the mid-position(s). For example: Max. effective number of turns corresponds to operating position 1 Min. effective number of turns corresponds to operating position 17 Operating position of mid-position(s): 9A; 9; 9B 4.2.2 Definition of "Raise" switching direction Here you define the direction in which the on-load tap-changer is to be switched with "raise" control, i.e. control towards the maximum or minimum effective number of turns. For example: From position "1" to "17", i.e. with "raise" controlling, the on-load tap-changer switches towards the minimum effective number of turns.

In contrast to on-load tap-changers, the required winding taps must be set with the transformer switched off on the high voltage and low voltage side. Off-circuit tap-changers are designed on the principle of a modular system allowing maximum rated through-currents of 200 A, 400 A 600 A, 800 A and 1000 A per current path. Off-circuit tap-changers DEETAP® DU are available with up to 17 operating positions. Switching concept The off-circuit tap-changer is changed over from one operating position to the next by rotating an insulating drive shaft. The DEETAP® DU off-circuit tap-changer is activated via a step-by-step gear with a hand wheel or operating wrench or with manual drive TAPMOTION® DD or motor-drive unit TAPMOTION® ED. The scope of supply of the DEETAP® DU includes the following basic circuits (for sketches of circuits, see 6.6): Linear off-circuit tap-changer for neutral and delta connection Single-bridging off-circuit tap-changer Double-bridging off-circuit tap-changer Series-parallel off-circuit tap-changer Star-delta off-circuit tap-changer Back-and-boost off-circuit tap-changer. © Maschinenfabrik Reinhausen 2012 EN inquiry_orderspecifications 91 6 DEETAP® DU off-circuit tap-changer type 6.1 DEETAP® DU off-circuit tap-changer type Figure 80 Off-circuit tap-changer type Figure 81 explains the individual items in the DEETAP® DU designation: Figure 81 92 Off-circuit tap-changer designations for DEETAP® DU inquiry_orderspecifications EN © Maschinenfabrik Reinhausen 2012 6 DEETAP® DU off-circuit tap-changer type Off-circuit tap-changers can be configured for a wide range of applications through parallel connection of several contact planes.

The COMTAP® ARS basically has two operating positions. The COMTAP® ARS is changed over from one operating position to the next by rotating an insulating drive shaft. This insulating drive shaft is operated via a 60° control gear that is driven via a TAPMOTION® ED motor-drive unit. Changing an operating position requires a 120° tap change of the insulating drive shaft. Two motor drive operations (double tap change) are therefore needed for a COMTAP® ARS operation. The COMTAP® ARS contact system has a contact circle diameter of 850 mm. During a COMTAP® ARS operation the through-current is commutated from one current path to another current path with the same potential. The contact system is equipped with special contacts for this purpose. The COMTAP® ARS can be used for different applications in combination with an on-load tap-changer. The COMTAP® ARS is primarily used to reverse the polarity of the regulating voltage in applications with large regulating ranges (e.g. phase shifter transformers).

Oil cooling unit (For detailed information, see operating instructions BA 2103288/00 DE) When on-load tap-changers with very high switching frequencies are being operated, Maschinenfabrik Reinhausen GmbH can require oil cooling for the on-load tap-changers due to the temperature calculations. In this case, the OF 100 oil filter unit is used as a pump for the oil cooling unit of the on-load tap-changer oil. Cleaning and drying the oil with the combination filter cartridge also offers the added advantage of longer maintenance intervals for the OILTAP® M and OILTAP® R (see operating instructions BA 018 for the OF 100 oil filter unit). Note: Only the fields marked with a * need completing for the control version in the motor-drive unit TAPMOTION®ED. Note: If the oil filter unit/oil cooling unit is retrofitted/supplied at a later date or if an existing oil filter unit/oil cooling unit is replaced, the MR serial number for the on-load tap-changer or the oil filter unit/oil cooling unit to be replaced should be stated. 9.1 General Figure 132 Oil filter/oil cooling unit If oil filter units for several transformers are ordered, the number of transformers should be stated. © Maschinenfabrik Reinhausen 2012 EN inquiry_orderspecifications 123 9 Oil filter unit OF100 9.2 Mechanical version Figure 133 Mechanical version 9.2.1 Number of pumps One pump unit with combination filter cartridge is installed per tap-changer column. 9.2.2 Filter type The oil filter unit is used for cleaning or for cleaning and drying the tap-changer oil in on-load tap-changers. It can be equipped with a choice of a paper filter (for cleaning) or a combination filter cartridge (for cleaning and drying). a) Cleaning on-load tap-changer oil with paper filter When on-load tap-changers are used in industrial transformers under extremely onerous conditions (high number of switching operations, consistently at full load and high frequent overloads) arcing will relatively soon cause contamination of the on-load tap-changer oil. This applies, for example, to on-load tap-changers incorporated into transformers on furnace or electrolytic plants. These service conditions can be met by an oil filter unit with a paper filter cartridge. The paper filter insert allows the on-load tap-changer oil to be cleaned of solid particles. The number of inspections requiring oil changes is reduced compared with the short intervals required in other cases. 124 inquiry_orderspecifications EN © Maschinenfabrik Reinhausen 2012 9 Oil filter unit OF100 b) Cleaning and drying the on-load tap-changer oil via combination filter cartridge When the on-load tap-changer is installed in areas where humidity is extremely high and the temperature in the oil conservator usually falls below the dew point every day, an increased water content in the on-load tap-changer oil and an accumulation of water in the carbon deposited on the insulating materials can occur. This will deteriorate the insulating properties of the on-load tap-changer. The combination filter cartridgenot only filters contaminating solid particles from the on-load tap-changer oil but also reduces the water content to a residual amount of < 10 ppm. The oil monitoring required can be reduced and oil treatment during maintenance may not be required. The combined filter cartridge is equipped with a paper filter on the outside (filter fineness ca. 9 mm) and filled with a drying agent on the inside (granules approx. 4 kg). 9.2.3 Replacement filter Additional filter inserts can be ordered here. 9.2.4 Thermal switch (signal emission TMedium > 25 °C) For a certain time (oil temperature <25°C), the thermal switch suppresses the signal from the oil filter unit's overpressure monitor. Reason: If the oil temperature falls (<25°C), the oil viscosity falls too. This is suppressed by the thermal switch so that the overpressure signal doesn't occur prematurely. 9.2.5 Continuous operation below 0° Celsius (thermostat for operation TMedium < 0 °C) Temperature sensor (model for cold weather operation) The low temperature model is recommended for regions where temperatures under 5 °C are to be expected in the oil filter unit or in the pipes during the winter months. This is the reason a temperature sensor is used which lets the unit run until the oil temperature in the system has risen above the preset value of +5°C (adjustable temperature range: 0 °-120 °C). © Maschinenfabrik Reinhausen 2012 EN inquiry_orderspecifications 125 9 Oil filter unit OF100 9.2.6 Control location a) Control inside the motor-drive housing The electrical control of the standard model is installed in the motor-drive unit housing.

The indicator instrument operates with a total resistance range of 60 - 2,700 ohms. Resistance model position indicator equipment is needed in the motor-drive unit. The resistor contact series (e.g. 10 ohms per step) must be produced to match the number of tap positions desired. The resistance module is connected to the indicator instrument and/or mains adaptor with bridge circuit via a signal line. Remote tap position indicator/indicator instrument (analog) for signal via measuring transducer (4...20 mA) (For a detailed description, see operating instructions 2220015/01) Note: A maximum of 19 tap positions is possible In the position indicator module, depending on the tap position a modified resistance value is provided at the measuring transducer's input in the motor-drive unit. This measuring transducer converts the resistance input signal into a constant current signal (e.g. 4...20 mA). The measuring transducer's input signal is basically defined as 10 ohms per step, the output signal can vary but is 4...20 mA as standard. The indicator instrument is adapted to the output signal and therefore indicates the motor-drive unit's position depending on the constant current signal. A measuring transducer is also provided in the motor-drive unit to convert the resistance signal into a constant current signal (4...20 mA). 10.2 Indication following the Selsyn procedure Figure 145 Indication following the Selsyn procedure 136 inquiry_orderspecifications EN © Maschinenfabrik Reinhausen 2012 10 Display instruments a) Selsyn indication (Weigel type) Dimensions: 96 x 96 mm 144 x 144 mm Figure 146 Selsyn indication, Weigel type b) Selsyn indication (INCON Model 1250B) Dimensions: 133 x 62 mm Figure 147 10.3 Selsyn indication, INCON type Lamp panel/light and control unit panel (For a detailed description, see operating instructions BA 247/02 DE) Figure 148 Lamp panel Function The lamp panel is used for the display of the current operating position of the on-load tap-changer and the manual change of the operating position from any location. The distance between this location and the motor-drive unit is limited to the voltage drop of the line and depends on the voltage applied on the motor-drive unit. The number of displayed operating positions depends on whether a continuous or decade contact series is connected to the lamp panel. © Maschinenfabrik Reinhausen 2012 EN inquiry_orderspecifications 137 10 Display instruments 10.3.1 Type of contact series Continuous contact series In the case of a system with a continuous contact series, a terminal of the position indicator module is assigned to each position of the on-load tap-changer. Only this terminal leads to a signal in the intended position, no other terminals do this. Since 28 lighting elements are provided on the lamp panel, a maximum of 28 positions can be displayed with one continuous contact series connected to a lamp panel. Decade contact series If more than 28 positions are to be displayed, a decade contact series must be connected to the lamp panel. In the process, the zero and first power are displayed separately. 10 terminals are assigned the values 0 to 9 and 10 terminals the values 00 to 90. In position 19, for example, the terminal with a value of 9 and the terminal with a value of 10 conduct signals. 10.3.2 Structure of lamp panel 1.

The signal is also available in the control unit free from potential for further digital processing (e.g. network control center). Via diode matrix The data is captured electrically at source, in this case at the motor-drive unit (diode matrix), transmitted over long distances and prepared anywhere, usually in the control room. The function of the signal transmitter is not dependent on the coding of the digital signals. Via resistor contact series The analog measured value is captured electrically at source, in this case at the motor-drive unit (resistance value) using a resistor contact series (10 ohms per step). This changeable resistance value is sent to the A/D converter input. The measured value is digitalized and output in code at the digital output. This signal is transmitted over long distances and prepared anywhere, usually in the control room. The function of the A/D converter is not dependent on the coding of the digital signals. 10.5.3 Connecting cable The scope of supply includes three different lengths of connecting cable between the signal converter and 7-segment display. © Maschinenfabrik Reinhausen 2012 EN inquiry_orderspecifications 141 11 MR worldwide 11 MR worldwide Australia Reinhausen Australia Pty.
