LW Series self-energy SF6 Circuit Breaker is a three-pole/single-pole AC 50Hz/60Hz outdoor high voltage power transmission equipment for the division of the rated current, fault current or conversion lines, transmission and distribution system for protection, control and operation can be opening, closing and fast automatic reclosing operation.
The LW36-126/3150-40 Self-Energized High Voltage SF6 Circuit Breaker is an outdoor circuit breaker designed for high-voltage AC systems. It is ideal for use in electrical grids with a maximum voltage of 145kV and a rated frequency of 50Hz.
The LW36-126 SF6 Circuit Breaker is designed for reliable performance in high voltage systems. With SF6 gas technology, it provides fast, efficient protection and requires minimal maintenance, making it ideal for power transmission networks.
In this technique, the pressure rise is obtained mainly by gas compression. The first high-voltage SF6 circuit-breaker with a high short-circuit current capability was produced by Westinghouse in 1959. This dead tank circuit-breaker could interrupt 41.8 kA under 138 kV (10,000 MV·A) and 37.6 kA under 230 kV (15,000 MV·A).
It is also suitable for use as a link breaker in network interconnections. This product uses SF6 gas as both the arc extinguishing and insulating medium. It is equipped with the latest self-energized arc extinguishing technology and features a new spring-operated mechanism.
In 1957, the puffer-type technique was introduced for SF6 circuit breakers, wherein the relative movement of a piston and a cylinder linked to the moving part is used to generate the pressure rise necessary to blast the arc via a nozzle made of insulating material (Figure 1).
