断路器操作回路详述

Protection and control of breaker operating circuit

断路器作为电力系统的重要元件,其操作回路在断路器切断一次回路过程中起着重要的辅助和保护作用。为了电力系统和设备的可靠运行,必须保证断路器和其操作回路的合理选型和使用。该文全面阐述了断路器操作回路的构成,详细介绍了各组成部分的工作原理及相关参数,指出了各种操作回路的不同,并对工程应用中的实际问题进行了探讨。

As an important unit of electric power system, breaker′s operating circuit plays an important role of assisting and protecting in cutting off the primary circuit. In order that the electric power system and equipment run reliably, breaker and its operating circuit must be selected and used correctly. This paper fully expounds the construction of breaker′s operating circuit, introduces each component′s working principle and relevant parameters in detail, points out the difference of each operating circuit, and probes the actual problems in engineering application.
