LW36A-126/145 Model Outdoor HV SF6 Circuit Breaker

The circuit breaker adopts to three-phase procelain pillar-type structure and outdoor design. Three phases commonly matches with a spring operating mechanism, Centre location , Three phase linkage, so the appearance is novel and exquisite. The circuit breaker takes SF6 gas as insulation & arc-extinguish medium , SF6 gas of three phases will connect during operation and the gas pressure and density are monitored by a pointer-type density controller. The arc self-extinguish principle and optimum design of movement system effectively improve the mechanical efficiency and furthest reduce the operating power consumption.  AS shown in fig. 1, Three-phase poles are installed at the common base, The control box is hoisted under the centre of base, And the spring operating mechanism and control unit are inside, The output shaft of mechanism connects with the crutch arm of central pole.
