Abstract
Description
Technical Field

[0002] Under the framework of ensuring the safe operation of the power system, implementing a 1000V high-voltage insulation performance test on the safety isolation barrier is a crucial link. This test aims to verify the working stability of the isolation safety barrier under extreme high-voltage conditions and its anti-electric leakage protection ability, thereby building a solid defense line for personnel and equipment safety.
[0003] However, under the current technical background, the design quality of the test tooling directly affects the accuracy and reliability of the test results. Specifically, if the insulation materials are not carefully selected and the insulation structure is not scientifically planned during the design stage of the tooling, it is very easy to lead to insufficient insulation efficiency of the tooling itself, thus unable to accurately reflect the true insulation level of the safety isolation barrier to be tested as an effective medium. In this case, the test results may deviate, misleading the evaluation of the insulation performance of the equipment.
[0004] To ensure the accuracy of the test results, the test tooling must integrate high-precision measuring instruments and sensors, which are like precise probes that can deeply detect and accurately record the insulation characteristics of the object to be tested. Any slight deficiency in test accuracy may become the source of magnifying errors and weaken the reference value of the test results.
[0005] In addition, considering the durability and maintenance convenience of the test tooling in actual application, its design should fully consider the convenience of replacing vulnerable parts, the intuitiveness of troubleshooting, and the maintainability of the overall structure. A reasonably designed test tooling should be able to quickly respond to fault signals, facilitate technicians to quickly locate problems and implement repairs, thereby effectively reducing maintenance costs and downtime, and improving the overall test efficiency and economic benefits.
