[0002] As we all know, safety testing mainly refers to the detection of whether the product has leakage, whether it is well grounded, and whether it will harm personal safety. The main detection items are voltage, leakage current, insulation resistance and grounding resistance. The existing automatic safety testing of motor controllers is independent of the production line and needs to be manually tested from the production line, and then placed on the safety testing system platform to complete the safety testing. Then the tested circuit board is taken out and put back into the production line. The existing safety testing equipment still has some defects.
