HV Circuit Breaker Fault Current

 

 

LW46-72.5/126 Series outdoor SF6 HV AC circuit breaker is high transmission and transformation electric equipment at rated voltage of 72.5/126kV, three-phase, AC 50Hz. It is applicable for opening and closing rated current, fault current and circuit conversion, so as to protect electric system. Moreover, three-phase quick automatic reclosing operation is available for equipment, and it also can be used as connecting circuit breaker.

The product adopts self-contained arc extinguish principle and be equipped with safe & reliable spring operation mechanism with excellent open & close capacity, reliable insulation, high current flow capacity and long mechanical endurance etc.

The circuit breaker is composed by three single poles and a spring operation mechanism installed on a same crossbeam. Therefore, it can be operated with three-phase together.

The circuit breaker has simple structure, easy for installation, low noise and high reliability..

The adaptation of self-contained arc extinguish has reduced operation power when breakng the short-circuit current, and matched with low operation power spring mechanism to increase operation reliability and mechanical life.

Meet requirement of high altitude (3000 and below) and extremely cold (-40℃)

The circuit breaker is overall debugging in factory, and its installation, maintenance and overhaul is
convenience at site.
The upper and down wiring board is symmetry structure and it can be fulfill with different kinds of connection.
