LW38-126 outdoor self-energizing high-voltage sulfur hexafluoride circuit breaker

LW36-126 type outdoor self-energizing high-voltage sulfur hexafluoride circuit breaker is suitable for AC 50Hz , 126kV power system, it is the control and protection equipment of the power system, and it can also be used as the contact circuit breaker.    

The circuit breaker takes SF6 gas as insulation and arc extinguishing medium, adopts the principle of self-energizing arc extinguishing, and is equipped with spring-operated mechanism, which is characterized by strong breaking capacity, small operating work and high reliability.    

Product structure characteristics
The circuit breaker adopts three-phase ceramic bottle pillar structure, designed for outdoor, three-phase with a SRCT36-C spring-operated mechanism, centered arrangement, three linked, so the appearance of novel circuit breaker to SF
Novel view of the circuit breaker to SF6 gas as insulation and arc extinguishing medium, operation of the circuit breaker three-pole SF6 gas should be connected, and the use of pointer-type density relay to monitor its pressure and density.
The pressure and density are monitored by pointer-type density relay. Due to the use of self-energized arc extinguishing principle and optimized design in the circuit breaker movement system, it improves the mechanical efficiency and reduces the operating power to a limited extent.”
