Outdoor sulfur hexafluoride circuit breaker(stainless steel case)

Description

LW38 series outdoor sulfur hexafluoride circuit breaker not only has the characteristics of compact structure and small area of enclosed composite electrical appliances, but also has the advantages of low price and convenient maintenance of open-type electrical appliances. And can carry out the whole substation primary equipment (including spacer support bus, tower, etc.) and secondary equipment of the general contract. 

Structural characteristics

LW38 series outdoor sulfur hexafluoride circuit breakers are available in indoor and outdoor layout. Each interval consists of a fixed part and a movable part. The fixed part includes isolating plug, earthing switch and local operation control cabinet, etc. The movable part is an electrical module that can be moved as a whole by assembling different electrical components together on a trolley base. The movable part of circuit breaker interval is composed of self-energy SF6 circuit breaker, current transformer and isolation plug. The movable part of the test interval consists of voltage transformer, lightning arrester and isolation plug. 

Main features

The structure form of circuit breaker spacing and test interval is consistent. The trolley and grounding switch are equipped with electric operating mechanism, including the circuit breaker, which can be operated in the local operation control cabinet. The secondary wiring from the local operation control cabinet to each component is plug-type, and the intelligent control cabinet can be provided to realize unattended operation. Flexible wiring mode, maintenance does not affect the user continuous electricity. Overall layout simple, beautiful, both can be applied to the indoor, also can be applied to the outdoors.
