Full-automatic electric performance test method and system for uninterrupted operation tool Technical Field The application relates to the technical field of electrical testing, in particular to a full-automatic electrical performance testing method and system for an uninterrupted operation tool. Background The electric performance of the uninterrupted operation tool is directly related to the safety and reliability of the electric operation, and the electric performance detection is a key link in the electric operation and maintenance. With the improvement of the requirements of the power industry on the operation efficiency, multi-station parallel tests have become necessary choices for meeting the detection requirements of large-scale uninterrupted operation equipment. The uninterrupted operation equipment safety detection platform usually adopts a full-automatic test mode, can simultaneously carry out electrical tests of at least 8 stations, covers the projects such as power frequency withstand voltage tests, leakage current tests and the like, and the test results are required to have reliability, repeatability and traceability so as to support the full life cycle management of the tool. However, in practical engineering application, three types of electrical phenomena are unavoidable when high-voltage tests are simultaneously carried out at multiple stations, namely, space electric field superposition is formed by multiple high-voltage stations to change local electric field distribution, leakage current changes of different stations caused by common grounding network to cause tiny fluctuation of grounding potential, and parasitic capacitance exists among samples, electrodes and leads of adjacent stations, so that coupling current can be introduced under high-voltage conditions. These phenomena do not constitute a safety risk for personnel or equipment, but can lead to abnormal fluctuations in the leakage current of the individual stations and poor repeatability of the test results. The existing test rules and automatic test platforms default that stations are mutually independent, and do not specially process the mutual influence among the stations in the test method level, so that when the test result is abnormal, whether the abnormality is caused by the defect of the insulation performance of the tested tool or caused by the electric mutual interference among the stations is difficult to distinguish, the accuracy and the reliability of the test result are seriously influenced, and the engineering application effect of the multi-station parallel test technology is restricted.
