Abstract

The invention provides a universal replaceable charge indicator, which comprises a case, a panel, a main circuit board and a wiring terminal bar, wherein the case is made of an insulation material, the wiring terminal bar comprises several rows of wiring terminals, the numbers of pin holes of each row of wiring terminals are different from each other, the case and the panel are detachably connected, the panel and the main circuit board are detachably connected, the main circuit board is arranged inside the case, the case is provided with a through hole used for connecting the wiring end of the main circuit board and the wiring terminal bar, the cross section of the through hole is greater than the cross section of the wiring terminal bar, and the wiring end of the main circuit board is in plugging-unplugging type connection with the wiring terminal bar through the through hole. According to the scheme, the panel and the case are detachably connected, and the main circuit board is in plugging-unplugging type connection with the wiring terminal bar through the through hole, so when a display fault occurs during charge, the inspection or the replacement can be conveniently carried out, the operation is simple, and in addition, the maintenance cost can be reduced. The numbers of the pin holes of each row of wiring terminals are different from each other, the wrong circuit connection during the maintenance process is avoided, and the safety is improved.

Description

technical field [0001] The invention relates to the field of electrotechnical technology, in particular to a universal replaceable electrification indicating device. Background technique [0002] With the development of urbanization, the grid structure is becoming more and more complex, and various types of electrical switchgears are also widely used in power distribution networks. In actual work, manual operations often have the possibility of making mistakes, and these misoperations are very likely to cause serious accidents and affect the normal operation of the power system. Personal injuries and operational accidents caused by the electrification of indoor high-voltage electrified bodies also occur from time to time. Therefore, the demand for an effective and practical indoor high-voltage universal replaceable electrified indicator device has become urgent. [0003] At present, most of the high-voltage switchgears are equipped with universal replaceable charging indica...
