技术领域 technical field
本发明涉及电力系统高压供电线路验电仪器的改进，是一种伸缩杆数字显示高压验电器。 The invention relates to the improvement of the electroscope for the high-voltage power supply line of the power system, which is a high-voltage electroscope with digital display of a telescopic rod.
背景技术 Background technique
电力系统高压供电线路检修时，首先需要测试检修线路是否断电，然后检修人员才能爬上电杆进行线路检修；现阶段城市供电电网常常是多条供电回路共用一个供电区间走廊，这种状况对线路检修验电工作带来了较大的困难：①.当一条供电回路断电后而相邻的供电回路未断电，断电回路的线路上会产生较高的感应电压，出现这种情况采取的措施是对检修线路接入地线泄放感应电压后检修人员才能上线操作；②.对于双回路供电的用户，线路进行检修时存在着用户因误操作向停电线路返送电源，使断电线路仍然存在着工作电压，此时必须查明原因并采取相应的措施，避免线路检修人员触电事故的发生。现有技术高压供电线路检修验电工作是采用高压验电器完成操作的，高压验电器是由触头、电阻元件、干电池、测试开关、警示灯、报警器及伸缩杆构成；高压验电器验电的操作过程是：将高压验电器中的触头与被检修的供电线路接触：若高压验电器无反应则表示线路已断电，若高压验电器中的警示灯及报警器同时报警，则表示线路上仍然存在着电压；现有高压验电器验电存在的问题是：高压验电器测试到检修线路上存在着电压，但高压验电器无法判断线路上的电压是感应电压还是工作电压，必须通过导电杆将线路电压引入到电压互感器并采用仪表进行测试，才能区分线路电压的性质以便采取相应的措施，线路检修验电操作费工费时，工作效率低。 When the high-voltage power supply line of the power system is overhauled, it is first necessary to test whether the maintenance line is powered off, and then the maintenance personnel can climb up the pole to carry out line maintenance; at this stage, the urban power supply grid often has multiple power supply circuits sharing a power supply interval corridor, which is very important for The line maintenance and inspection work has brought great difficulties: ①. When one power supply circuit is powered off and the adjacent power supply circuit is not powered off, a higher induced voltage will be generated on the line of the power-off circuit. This situation occurs The measures taken are to connect the maintenance line to the ground wire to release the induced voltage before the maintenance personnel can go online to operate; ②. For users with dual-circuit power supply, there is a possibility that the user may send power back to the power failure line due to misoperation during line maintenance, causing power failure There is still working voltage on the line, and the cause must be found out and corresponding measures must be taken at this time to avoid electric shock accidents for line maintenance personnel. The prior art high-voltage power supply line inspection and inspection work is completed by a high-voltage electroscope, which is composed of contacts, resistance elements, dry batteries, test switches, warning lights, alarms and telescopic rods; The operation process is: contact the contact in the high-voltage electroscope with the power supply line to be repaired: if the high-voltage electroscope does not respond, it means that the line has been cut off, and if the warning light and alarm in the high-voltage electroscope alarm at the same time, it means There is still voltage on the line; the problem with the existing high-voltage electroscope is that the high-voltage electroscope detects that there is voltage on the maintenance line, but the high-voltage electroscope cannot judge whether the voltage on the line is an induced voltage or a working voltage. The conductive rod introduces the line voltage to the voltage transformer and uses an instrument to test it, so that the nature of the line voltage can be distinguished and corresponding measures can be taken. The operation of line maintenance and inspection is labor-intensive and time-consuming, and the work efficiency is low.
