【摘要】 文章重点介绍了3.3kV移动变电站漏电保护工作原理及动作电阻值的确定方法,给出了系统硬件设计方案,并在仿真环境下进行了模拟试验。试验结果表明:系统保护方案可行,参数选择合理,动作灵敏可靠。
【Abstract】 The working principle and determining method of action resistance value of leakage protection of 3.3 kV movable substation were introduced in this paper. The system’s hardware circuit of 3.3 kV leakage protection was given and the simulation test was carried out under artificial condition. The simulation test showed that the technical scheme is feasible, parameters are reasonable and the tripping is reliable and sensitive.
