Problems solved by technology

Frequent line change operations and changes in test parameters require a lot of manpower, which not only consumes time and effort, but also increases the potential error rate and limits the improvement of work efficiency.
[0005] There are also manual setting of test parameters, and the use of embedded technology to realize automatic processing of line change operations. Although this method improves some work efficiency, it still requires a lot of manpower investment, which also limits the improvement of work efficiency.

Description

technical field [0001] The invention relates to the technical field of electric safety tests, in particular to an automatic test system for electric safety tests and a test method thereof. Background technique [0002] Electrical safety test is one of the basic items of electrical product type test, mainly including insulation resistance test, dielectric strength test and impulse voltage test. GB / 14598.27 has clear requirements for the test parts of insulation resistance test, dielectric strength test and impulse voltage test: between independent circuits. This requires the tester to apply the test voltage between the independent circuits during the test, and the frequent line change operation during the test greatly hinders the improvement of work efficiency. [0003] Due to the different test mechanisms, two different equipment are required to complete the insulation resistance test, dielectric strength test and impulse voltage test, one to complete the insulation resista...
