Interruptor de ruptura de carga de gás 15KV SF6

Name: Interruptor de ruptura de carga de gás 15KV SF6
Brand: Zhuhai Gopower Smart Grid Co., LTD

O interruptor de desconexão montado em pólo de 15 kv é adequado para tensão nominal de 15kV, corrente nominal 630A, quebra de rede de distribuição de 50/60Hz. A corrente de carga ou a corrente de sobrecarga em um sistema de energia isola automaticamente as seções defeituosas da linha de distribuição.

Com o mais recente controlador eletrônico de tecnologia, esteInterruptor de quebra de carga manualRealiza operação manual, operação elétrica e operação remota. O controlador eletrônico é instalado na caixa de aço inoxidável e pode ser usado sob várias condições climáticas. Além disso, o cabo de interruptor de quebra de carga de 15kv e os modems sem fio podem ser instalados na caixa para realizar o monitoramento remoto e controle. A instalação e o arranjo simples no poste são convenientes, rápidos e de baixo custo de construção.

O 15KVInterruptor de desconexão montado em posteÉ feito de material durável, resistente à corrosão comprovado. (Placa de aço inoxidável 304L para navios de guerra), garantir uma longa vida útil (30 anos), nosso interruptor de quebra de carga de 15kv pode realizar uma série de operações, com as características ideais do equipamento superior do pólo.
Cada umGOPOWERO interruptor de quebra de carga de 15kv foi preenchido com gás sf6 antes de sair da fábrica, tratamento selado. O teste do interruptor de desconexão montado em pólo de 15 kv foi realizado de acordo com IEC60265-1 padrão GB 3804-1990 (1988).

SF6 Gas 15KV Load Break Switch In Pole Mounted Switch Solution

15kv load break switch has a certain interrupting capacity because of the interrupting device, but 15 kv pole mounted disconnect switch is not as strong as the interrupting capacity of the circuit breaker, which can split the normal working current, and in the case of short circuit, he can only silently withstand the short circuit current, and if this time the manual or electric breaking may explode, so the load switch is generally used together with the current limiting fuse (load switch + fuse is not the standard configuration, and can also be used without fuse) In the event of an overload or short circuit, the circuit is broken by a fuse. In order to save costs, the load switch + fuse can replace the circuit breaker. Inquiry more pole top switches
