++++General
RMR-24/46kV is completely insulated SF6 SAFERIN
（hereinafter short as SF6 Gas insulated Switchgear）
This product is in conformity with the standards the
GB/IEC standard and the design of a high safety
combined switch cabinets.
The system of RMR-24/36kV of combined switch
cabinets can be divided into three kinds of unit cabinet：
++++ 3 position cable connection unit (Cable switch
unit), additional live shows and configuration of surge
arresters and grounding fault component. Code C
++++3 position switch and fuse tripping system and
earthing switch interlock system fuse combined electrical
unit (Fuse combination unit), additional live shows and
configuration of surge arresters and grounding fault
component. Code F
++++3 position switch and vacuum circuit breaker
combined appliances unit (Vacuum circuit breaker unit),
additional current transformer, live shows and
configuration of surge arresters and grounding fault
component. Code V
The combination of the current transformer and the
microcomputer protection to constitute the basic circuit
protection function.
Microcomputer protection using passive protection and
CT electric no need of additional PT power supply
