谈负荷开关+熔断器组合电器的转移电流

Tall about the transfer current in the switch and fuse combinatian

负荷开关+熔断器组合电器已被大量应用于10kV终端配电室用来替代传统的断路器作为终端配电变压器的一次侧保护设备。这种保护方式简单、快捷、有效,并能节省投资成本。在选用负荷开关+熔断器组合电器时,应特别注意"转移电流"。

The switch and the fuse combination has been used to 10kV supply to replace circuit breaker as the transformer protection device.This way is simple,quick and protected effectively,and can save the investment cost.In selecting the combinations,should pay special attention to the transfer current between the switch and the fuses.
