Problems solved by technology

[0003] Existing electrical test devices are single-function test instruments. For example, different electrical equipment uses different voltages, including three-phase four-wire voltage, two-wire voltage, DC voltage, AC voltage, etc. Different equipment Need to use different test instruments for detection
Existing test instruments can only detect one line voltage, and the test instrument needs to be replaced when detecting another line voltage, which leads to complicated measurement work and low efficiency. If the corresponding instrument is not carried, the test period will be delayed, so It is necessary to improve the electrical test device

Description

technical field [0001] The invention relates to the technical field of electrical testing, in particular to an electrical testing device. Background technique [0002] Electrical test is before the electrical system and electrical equipment are put into use, in order to determine whether there are quality problems in installation or manufacturing, to determine whether the newly installed electrical equipment can be put into operation normally, and to test the individual electrical equipment in the electrical system. Insulation performance, electrical characteristics and mechanical properties, etc., shall be tested and verified item by item in accordance with the relevant provisions in standards, regulations, and specifications. Through these tests and verifications, defects in the manufacture and installation of electrical equipment can be found and eliminated in a timely manner to avoid quality problems and ensure that the electrical system and electrical equipment can be p...
