35kv 630A High Voltage Sf6/Cabinet Ring Main Unit/Gas Switchgear
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.

1. The structure of the cabinet is assembled, and the circuit breaker adopts a handcart floor type structure;
2. Optional: the joint design of vacuum circuit breaker (ZN85-40.5/3AV3), Xiamen Huadian pole sealed vacuum
circuit breaker (VEP-40.5), AREVA SF6 circuit breaker (FP4025D), Schneider SF6 (SF2), circuit breaker with
circuit breaker with interchangeability, easy replacement, convenient.
3. The handcart frame is provided with a screw rod, a nut propelling mechanism, an overrunning clutch, and the
handcart can be easily moved, and the propulsion mechanism can be prevented from being damaged by misoperation.
4. The interlock of the main switch, the handcart and the door of the switch adopts the forced mechanical locking
mode to meet the "five safety" interlocking function;
5. Fast earthing switch is used for circuit short connection and earthing;
The switchgear cabinet is designed according to the standard of metal clad enclosed switchgear in GB3906 and IEC298.
Overall the cabinet and take part (CART) is composed of two parts, the body structure adopts aluminum zinc coated sheet
or galvanized plate bolted composite molding, metal plate isolation switch internal separation for the circuit breaker room,
main bus chamber, a cable chamber and the relay control room, and all the metal parts are reliable grounding cabinet
main loop system of each isolation are independent of pressure release channel in the indoor cable can set 10*60mm2
grounding bus.
