Summary of LW36B-126 High Voltage SF6 Circuit Breaker :
This product is based on the technology of LW36A/B-72.5/126/145, developed by Xi'an HV Electrical Apparatus Institute and HEAG group. It absorbs experiences and technics in similar product manufacturing and perfected as a new generation of self-evolving SF6 HV circuit breaker. LW36A/B-72.5/126/145 is used to control and protect circuit in 72.5/126/145kV and AC 50/60Hz power system. It is SF6 insulation with CT30 spring operation mechanism.
Technical Specification of LW36B-126 High Voltage SF6 Circuit Breaker :
Spring Operating Mechanism of LW36B-126 High Voltage SF6 Circuit Breaker :
Diagram A: After circuit breaker is closed, the close and open spring store energy, inside crutch arm and outside crutch arm be ar moment from anti-clockwise, once the opening winding electrified, the lock releases and rotate in anti-clockwise driving by open spring, and inside crutch arm open circuit breaker. The moment is locked up by keeping engine and engine under opening state. (On diagram B)
Diagram B: When spring mechanism is opening, close spring storage, ratchet wheel axis bear moment from opening spring in anti-clockwise, the moment is locked up by holding engine and opening engine. When opening winding electrified, the cam and ratchet wheel connected with clocking devices re lease. The cam driving by close spring in anti-clockwise, and its moment depresses open spring as to open the circuit breaker.
Diagram C: As the circuit breaker finished with closing, close spring is releasing, (as that in diagram A) the pawl axis connects with motor by gear. The motor start up instantly and open spring store energy.
