低压双回路自投时间测试整定方法的研究

Testing and Adjusting Methods Research of Automatic Change over Time in the Low-Voltage Double-Loop Power Supply System

针对一级负荷高可靠性的供电要求,提出了一种测试低压双回路供电系统自投时间的方法,并精确地测试了双回路自投时间。进而,根据断路器特性和设备对停电间隙的要求,对断路器自投时间进行了整定。

To counter the high reliability demand of class I load power supply, a method of test automatic change over time in the low voltage double-loop power. supply system has been put forward, at the same time, the automatic change over time of low voltage double-loop power supply system has been tested accurately. Moreover, based on the demand of conventional circuit breaker characteristic and equipment vs power cut time, the automatic change over time of conventional circuit breaker was adjusted.
