Interlock controller for preventing live laying ground wire and switching-on with ground wire

Abstract

本实用新型公开一种变电站倒闸操作时用的保护装置,即防止带电装设接地线及防止带接地线合阐的联锁控制装置,它包括刀闸柱、刀闸把手、接地桩,其特征在于,在刀闸柱上设有接地联锁组件,刀闸把手联锁组件;设有电气联锁组件;所述的接地联锁组件中接地桩的径向位置设有接地桩插孔,接地桩插孔配套有接地电磁铁,其拖动接地插销进入或退出接地桩插孔;所述的刀闸把手组件中刀闸把手的径向位置设有刀闸把手插孔,刀闸把手插孔配套有刀闸电磁铁,其拖动刀闸插销进入或退出刀闸把手插孔;电气联锁组件,可以由设在现场的电磁铁作成,也可以设在控制室内继电器组或控制计算机联合电磁铁作成,有行程开关接点和刀闸辅助接点为输入信号。从结构上实现带电不能装设接地线和带接地线不能合闸,杜绝了事故发生。
The utility model discloses a protecting device used for a transformer station during reverse switching operation, namely an interlocking control device which prevents a grounding wire from electrified installation and prevents closing operation with the grounding wire, which comprises a knife switch column, a knife switch handle and a grounding stake. The utility model is characterized in that the knife switch column is provided with a grounding interlocking component, an interlocking component of the knife switch handle and an electrical interlocking component, wherein a grounding stake jack which is provided with a grounding electromagnet in a matched mode is arranged in the radial position of the grounding stake of the grounding interlocking component, and the grounding electromagnet drags a grounding connector pin into or out of the grounding stake jack; the jack of the knife switch handle which is provided with a knife switch electromagnet in a matched mode is arranged in the radial position of the knife switch handle of the component of the knife switch handle, and the knife switch electromagnet drags a knife switch connector pin into or out of the jack of the knife switch handle; the electrical interlocking component can be made of an electromagnet arranged on a site, and can be made of an electromagnet combined with a relay group in a control room or a control computer, and a travel switch connecting point and a knife switch auxiliary connecting point receive input signal. The utility model realizes that the grounding wire can not be installed when electrified, and closing operation can not be done with the grounding wire by structure so as to prevent an accident from happening.
