利用快速接地开关的开关柜故障电弧保护方法
Fault Arc Protection Method for Switchgear Cabinet Using Fast Earthing Switch
摘要
Abstract
With the development of social economy,the power system has become increasingly complex,the switch-gear cabinet,as one of the important equipment to maintain stable operation of the power system,also plays an in-creasingly important role,and attention shall be paid to the the safe protection of the arc fault of the switchgear cabi-net.In order to achieve effective protection against the arc fault of the switchgear cabinet,the causes and harm due to the arc fault inside the switchgear cabinet are introduced firstly in this paper.Then,the existing methods for dealing with the arc fault of the switchgear cabinet is compared,the insufficiency of the pressure relief channel method of the switchgear cabinet and of the fault diagnosis information transmitted to the host circuit breaker is analyzed,and a method of using fault arc detection and rapid earthing switch to protect the switchgear cabinet and prevent major acci-dents in the switchgear cabinet is obtained.By comparing the existing fault detection methods and the two driving modes of the operating mechanism for the fast earthing switch,the scheme of combining the arc overcurrent protec-tion criterion and the electromagnetic repulsion mechanism is introduced,which can realize the effective protection of the internal arc fault of the switchgear cabinet.关键词
