摘要
断路器非全相运行保护的不同技术方案有不同的特点。结合福建省电力系统情况,阐述了配置高压断路器非全相保护的必要性,分析了当前非全相保护的常见方案的技术特点及适用范围,探讨了3/2断路器接线的非全相保护方案的选择,以及设备在运行维护和装设中应注意的事项。
The various solutions of the open-phase protection to handle the open-phase running of the breakers have their own advantages and disadvantages. Taking the electric system of Fujian Province as an example, this paper depicts the necessity to equip the high voltage (HV) breakers with the open-phase protection system, analyzes the technical features and application ranges of the common solutions of the current and openphase protection, explores the solution selection of the open-phase protection for 3/2 breaker connection, and presents some issues needing concern in the operation maintenance and installation of the devices.
