| 摘 要： | 智能断路器中的漏电保护和接地保护其原理有些相似,均是测量三相(三极断路器)或三极加N极(四极断路器)的电流矢量和,但其测量范围、测量精度和应用场合又不相同,分析了框架断路器、塑壳断路器、漏电断路器和六氟化硫真空断路器的接地保护和漏电保护原理及应用,使用时要根据不同的保护要求选择不同类型的断路器。

| Abstract: | The principle of electric leakage protection in the intelligent circuit-breakers is similar to that of ground protection. They are to measure current vector sum of three phases of three-pole circuit-breakers or three poles of four-pole circuit-breakers with N-pole,but there are differences in measuring range,survey precision and application situation. Analysis was made on the principle and appli-cation of electric leakage and ground protection in air circuit-breakers,moulded case circuit-breakers,residual c... |
