摘要/Abstract

摘要： 备用电源自动投入装置旨在提高供电的可靠性，但母线故障时备用电源自动投入装置的自动切换有可能扩大事故影响的范围和程度。介绍了备用电源自动投入装置在广东珠海金湾发电有限公司的应用情况，提出了备用电源自动投入装置切换的改进方法。改进后，进线开关故障跳闸时，母联开关不会自动合闸，达到了闭锁备自投切换的目的。

Abstract: The reserve power supply autoputinto device is designed to increase the reliability of the power supply. However, when the bus fault occurred, the automatic switchover of the reserve power supply autoputinto device may enlarge the accident influencing scope and accident seriousness. The application of the reserve power supply autoputinto device in Guangdong Zhuhai Jinwan Power Generation Company Limited was introduced. An improvement switchover method of the reserve power supply autoputinto device was put forward. After the reserve power supply autoputinto device was improved, when the input switch tripped caused by a fault, the bus tie switch should not switch on automatically; so the switchover of the reserve power supply autoputinto device is blocked.

Key words: reserve power supply auto-put-into device, input switch, bus tie switch, automatic switch-on, blocking
