| Abstract: | In order to ensure the safety of the mine power supply system,it is necessary to install various protection switches.However,due to various reasons,these protection switches have the problem of over tripping during operation,which greatly reduces the role of the protection system.This paper analyzed the causes of the over-trip phenomenon of the protection switch,introduced several methods to prevent the over-trip,and emphatically analyzed the application of the over-trip protector ZBT-11C,which can provide some reference for the mine to prevent the over tripping accident. |
