摘要
备自投装置是为了提高电网的安全、可靠运行所采取的一种重要措施。本文阐述了目前广泛使用的110kV纵联备自投的基本原理,分析了110kV备自投装置断路器位置接点的引取问题及与保护装置二次回路的配合问题,探讨了110kV备自投应用中的危险点及防范措施。
The backup power source device(BZT) is an important measure to improve the safe and reliable operation of the power grid.This paper describes the basic principle of the current widely used 110 kV longitudinal BZT,and analyzes some problems such as the selection of the contact of circuit breaker and the cooperation with secondary circuit of protection devices,then discusses the dangerous point of application and the preventive measures.
