Problems solved by technology

[0003] At present, most of the existing comprehensive testing equipment for electrical safety performance in the market has a simple structure and cannot fix the electrical appliance under test well. During the testing process, the movement of the electrical appliance under test will have a bad influence on the test results of the testing instrument or the electrical appliance itself. Therefore, It is necessary to design a comprehensive test equipment for safety performance that is easy to fix the electrical appliances under test

Abstract

The invention belongs to the electrical appliance safety testing equipment technical field and relates to a safety performance comprehensive test instrument. The safety performance comprehensive test instrument includes a detection arrangement stage and a detection instrument; the detection arrangement stage is connected with the detection instrument through a data transmission line; the periphery of the detection arrangement stage is uniformly provided with clamping portions and air cylinders, wherein the air cylinders are connected with the clamping portions through connecting rods; and the detection instrument is provided with a feedback module and a human-machine interaction module. The safety performance comprehensive test instrument is improved based on the prior art. The clamping portions which are connected with the air cylinders and are arranged on the detection arrangement stage can fix an electrical appliance to be tested, and a clamping force and clamping time can be effectively guaranteed, and it can be ensured that the electrical appliance to be tested is in a stable stationary state in a whole detection process, and therefore, detection results are more accurate.

Description

technical field [0001] The invention belongs to the technical field of electric appliance safety testing equipment, in particular to an electric appliance safety performance comprehensive tester. Background technique [0002] The safety performance of electrical products needs to be tested before leaving the factory, generally including AC / DC withstand voltage test, insulation resistance test, grounding resistance test, the existing safety performance tester, the test items of the tested objects are all carried out one by one, The time spent testing a subject is the sum of the individual time. With the development of automation technology, the time for safety performance testing has gradually become the bottleneck of the entire production line. Speeding up the testing speed can improve the efficiency of the entire production line. Based on this, how to invent a comprehensive test equipment for electrical safety performance, which can measure two test items at the same time ...
