Measuring equipment and measuring method for leakage currents of high-voltage holding test of security equipment

Abstract

The invention discloses measuring equipment and a measuring method for leakage currents of a high-voltage holding test of security equipment. The measuring equipment for the leakage currents of the high-voltage holding test of the security equipment comprises a mobile testing platform and a modular current detection alarm device. The modular current detection alarm device is mounted on the mobile testing platform which comprises an insulating support, a high-voltage end, a grounding end and a guide rail ruler. The modular current detection alarm device is in series connection with the grounding end. The measuring method for the leakage currents of the high-voltage holding test of the security equipment comprises the following steps of drawing an equipment wiring diagram, choosing the modular current detection alarm device, manufacturing the mobile testing platform, debugging and mounting and operating measurement. The measuring equipment and the measuring method for the leakage currents of the high-voltage holding test of the security equipment can effectively and accurately measure the leakage currents on the surface of the security equipment, solve the problem that the security equipment is difficult to judge to be qualified or not, and guarantee the personal safety of an operator and the safe and stable operation of a power grid.

Description

technical field [0001] The invention relates to a leakage current measurement technology of a power system, in particular to a measurement device and a measurement method for a leakage current of a safety tool withstand voltage test. Background technique [0002] The high-voltage test team should conduct withstand voltage tests on safety equipment such as insulating ladders and insulating rods regularly to judge whether they are qualified and can be used. This kind of safety tool is a tool to ensure personal safety for on-site workers in substation operation, line inspection, and distribution inspection. The withstand voltage test of safety appliances is the most effective and the most direct way to reflect the insulation level of safety appliances, so the withstand voltage test is of great significance to verify the insulation level of appliances. At present, the method of pressure test of safety equipment is to put the tested safety equipment on the ladder, fix a certain ...
