火力发电厂的高压厂用电源设计中,F-C柜被广泛应用于电动机电源回路,在电动机F-C电源柜中高压限流熔断器作为短路保护,开断短路电流；而综保装置作为过载保护,配合接触器切断过载电流。两者互相配合组成两段式电流保护。文章分析了F-C回路中电动机保护用熔断器的选择方法及与微机保护的配合原则,并对工程实例进行了分析。
火力髮電廠的高壓廠用電源設計中,F-C櫃被廣汎應用于電動機電源迴路,在電動機F-C電源櫃中高壓限流鎔斷器作為短路保護,開斷短路電流；而綜保裝置作為過載保護,配閤接觸器切斷過載電流。兩者互相配閤組成兩段式電流保護。文章分析瞭F-C迴路中電動機保護用鎔斷器的選擇方法及與微機保護的配閤原則,併對工程實例進行瞭分析。

F-C circuit is widely used for motor power in thermal power plant. In the F-C circuit, the high-voltage current-limiting fuse opens short-circuit current as short-circuit protection, meantime computerized protection with contact opens overload current as overload protection. They make up two-stage overcurrent protection by working together. This article describes the selection method of the fuse for motor in the F-C circuit, and the coordination principle between the fuse and the computerized protection, analyses the engineering examples.
