GAS INSULATED SWITCHGEAR MODEL HS-X (TYPE1) 12kV/24kV Advanced environmentally friendly switchgear A-199-4-C6718-E HQ1209 Printed in Japan (MDOC) Revised Publication, effective Sep. 2012. Superseding Publication, A-199-4-C6718-D of Mar. 2009. Specifications are subject to change without notice. Advanced environmentally friendly switchgear Mitsubishi Electric Corporation has designed and manufactured a substantial amount of high quality switchgear all over the world. This vast experience was drawn on to produce the next generation of advanced environmentally friendly switchgear, the ”HS-X”. H igh reliability - Years of trouble free operation The reliability has been increased even further by the application of an electro-magnetic vacuum circuit breaker (VCB) operating mechanism. With fewer parts†2 the chances of failures occurring have decreased. F †2 35% less parts than conventional Mitsubishi Electric spring VCB operating mechanism. lexible design - Suitable for many applications S Designed so that several orientations of cable terminations (power and control) entry are available, makes it one of the most flexible switchgear on the market. afe Design - Ensures operator’s safety In the event of an internal arc, any arc fault gas will be directed away from the operator (through the top of the panel). With the benefit of GIS design concepts, there are no live parts exposed inside the panel which ensures utmost safety for operators. S imple installation - Quick and easy No gas processing is required during site installation and commissioning, which simplifies planning and reduces time required for installation, and maintains the high quality of the switchgear during transportation. L ow maintenance - Reduction of maintenance costs The circuit breaker’s advanced electro-magnetic operation does not require maintenance for over 15 years†3. The circuit breaker and disconnecting / earthing switch are hermetically sealed in a tank and together with the application of original anti-oxidation grease to the moving parts of the disconnecting / earthing switch enable smooth long-term operation for 15 years or more. †3 Under normal operation conditions according to IEC standard. U ser friendly - Simple operation CONTENTS A simple layout of the operating mechanisms and mimic diagram at the front of the panel leads to straightforward operation. Additionally this reduces the chance of maloperation.

This relay combines protection, measurement and control functions into one compact flush door mounted unit. Current transformer ratios are adjustable in combination with the use of wide range current transformers. Control devices and equipment and wiring are moduled. Functions are readily interchangeable and the enclosure of live parts provides a high level of reliability. The busbar is independently solidly insulated for each phase, which eliminates any chance of phase-to-phase faults. Also no gas processing is required during site installation or maintenance. : 0.13 : 0.17 : 0.12 : 0.15 BUS †1 : The application standard is for 630A rating with dry air only.
