海上平台电网的快速限流熔断器
摘要：
一种海上平台电网的快速限流熔断器，包括底座、快速隔离器、限流熔断器、电器控制器、高压隔离变压器及低压信号控制箱，所述底座上设有快速隔离器、支持绝缘子及高压隔离变压器，所述的快速隔离器一端与支持绝缘子连接，另一端与电子控制器及高压隔离变压器连接，高压隔离变压器与低压信号控制箱连接，所述限流熔断器与快速隔离器连接，所述低压信号箱通过设置在高压隔离变压器上的低压信号控制箱连接口与高压隔离变压器连接；本实用新型大大降低了故障电流的总能量（约为普通断路器的1/200），从而更有效地保护了电力主设备免受损坏。
摘要（英）：

A rapid current-limiting fuse of an offshore platform electrical network comprises a pedestal, a rapid isolator, a current-limiting fuse body, an electronic controller, a high-voltage isolation transformer and a low-voltage signal control box, wherein the rapid isolator, a support insulator and the high-voltage isolation transformer are arranged on the pedestal; one end of the rapid isolator is connected with the support insulator, and the other end of the rapid isolator is connected with the electronic controller and the high-voltage isolation transformer; the high-voltage isolation transformer is connected with the low-voltage signal control box; the current-limiting fuse body is connected with the rapid isolator; and the low-voltage signal box is connected with the high-voltage isolation transformer via a low-voltage signal control box connecting port which is arranged in the high-voltage isolation transformer. According to the utility model, the total fault-current energy of the rapid current-limiting fuse is reduced to about 1/200 that of a common circuit breaker, thereby protecting main power equipment against damage in a more effective way.
