General
RMR-40.5KV fully insulation SF6 gas switchgear(SF6 gas ring main unit)is according to GB/IEC standard to design a high safety margin modular switchgear.
RMR-40.5KV system combination switchgear systems can be divided into three main unit cabinet:
(1) A three-position switch cable switch unit, and can be configured to display additional charge arrester and ground fault components. Code C.
(2)A three-position switch plus fuse tripping system and a lower grounding switch interlock system fuse combination unit, and can be configured to live display, display additional charge arrester and ground fault components. Code F.
(3) A three-position switch plus vacuum circuit breaker combination unit, and can be configured to current transformer, live display, display additional charge arrester and ground fault components. Code V.
The combination of the current transformer and microcomputer comprehensive security constitute the basic line protection.
Microcomputer comprehensive security passive protection, CT to take power without a separate power supply PT.
