变压器总保护开关和联络开关采用四极断路器刍议

Discussion about General Protection Switch and Loop Switch of Transformer Adopting Quadrupole Circuit Breaker

通过一个具体建筑工程的实际案例分析,说明变压器总保护开关和联络开关采用四极断路器有明显缺陷,导致有些情况下供电系统方案难以实施,进而建议推广采用三极断路器。

Through analyzing an actual construction engineering, it was illuminated that general protection switch and loop switch of transformer adopting quadrupole circuit breaker had evident defects. In some cases, the power supply system scheme was not easy to be implemented. So it suggested that the three-pole circuit breaker should be adopted.
