一种新型高压设备验电指示电路的研究与设计

Research and Design of an Electricity Test Indication Circuit for a New Type of High Voltage Equipment

在检修高压设备时需要对其是否带电进行校验,而设备验电结果的可靠性对保障电力作业人员安全具有重要意义。传统的验电装置一端直接与高压带电体进行电接触,另一端与大地接触,间接判断是否带电,这就给检修人员判断高压设备是否带电带来麻烦,既耗时又不直观。基于电场耦合原理,设计出一种高压线路验电指示电路,可以在非接触状态下实现高压设备的带电信息检测,对提高检修人员的操作安全性起到十分重要的作用。

When the high-voltage equipment is being repaired,it is necessary to verify whether it is live or not.The reliability of electrical inspection results is of great significance to the safety of electric power operators.One end of the traditional electrical inspection device is in direct electrical contact with the high-voltage charged body,and the other end is in contact with the earth to indirectly judge whether it is live,which brings trouble to the maintenance personnel to judge whether the high-voltage equipment is live,which is not only time-consuming but also unintuitive.Therefore,based on the electric field coupling principle,a high-voltage line power inspection indication circuit is designed,which can realize the live information detection of high-voltage equipment in a non-contact state,and play an important role in improving the operation safety of maintenance personnel.
