Abstract

The invention provides a leakage current testing auxiliary device, comprising a lead wire rod (2) and a lead wire (3), wherein a first end of the lead wire rod is connected with a testing instrument body (1); the lead wire (3) is arranged in the lead wire rod (2) in a penetrating manner; and one end of the lead wire (3) is connected with a tested lightning arrester and the other end of the lead wire (3) is connected with a measuring meter on the testing instrument body (1). According to the leakage current testing auxiliary device disclosed by the invention, the problems in the prior art that working efficiency of a test is low and too many risk links exist are effectively solved.

Description

technical field [0001] The invention relates to the field of electric power safety, in particular to an auxiliary device for testing leakage current. Background technique [0002] Leakage current test is one of the important items in the preventive test of equipment (transformer, lightning arrester, etc.) in substation. The experimental device is connected as figure 1 As shown, in the test, the voltage of the test wire is very high, and there will be strong corona discharge around it, which will affect the accuracy of the test data. The smaller the minimum distance L between the test wire and the grounding structure supporting the arrester, the greater the impact. [0003] like figure 2 As shown, in order to ensure the safety of the test process and the accuracy of the test data, it is usually necessary to repeatedly adjust the position of the test instrument so that the minimum distance L between the test lead and the grounding structure is increased to L'. In order to ...
