1.Overview
This product 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 controlandprotect circuit in 72.5/126/145kV and AC 50/60Hz power system.It is SF6 insulation with CT30 spring operation mechanism.
2. Ambient condition

2).Good insulation capacity;
3).Dependable mechanical maintenance;
4).Reduction of noise;
5).Convenient installation and debugging;
6).Dependable air-proof feature;
7).Long mechanical life and maintenance-free;
8).Safe and reliable operation.
4.Spring operating mechanism
Diagram A: After circuit breaker is closed,the close and open spring store energy,inside crutch arm and outside crutch arm bear moment from anti-clockwise,once the opening winding electified,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 electified, the cam and ratchet wheel connected with clocking devices release. 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.
