| 避雷器带电测试仪是用于氧化锌[MOA] 泄漏电流的测量分析。主要是用于测量阻性电流，从而分析氧化锌老化和受潮的程度。氧化锌避雷器在长期运行时会出现内部绝缘受潮及阀片老化等缺陷，导致避雷器泄漏电流的增加，严重时还会引起热崩溃，影响电力安全生产，因此需要定期进行预防性试验，确定其工作状态是否良好。 Lightning arrester live tester is used to measure and analyze the leakage current of zinc oxide [MOA]. It is mainly used to measure the resistive current, so as to analyze the aging and moisture of zinc oxide. Zinc oxide arrester will have defects such as dampness of internal insulation and aging of valve plate in long-term operation, which will lead to the increase of leakage current of arrester, thermal collapse in serious cases and affect the safety of power production. Therefore, preventive tests need to be carried out regularly to determine whether the working status of the arrester is good or not. 现场带电测试符合中华人民共和国电力行业标准《DL474.5—92现场绝缘试验实施导则—避雷器试验》的要术。也可用于实验室做出厂和验收试验。配有RS-232通信接口，可将数据上传至计算机处理。 On-site live test meets the requirements of the People's Republic of China Electric Power Industry bianyaqigs.37ix.com.cnmojuyz.37ix.com.cnmojulbs.37ix.com.cnStandard DL474.5-92 on-site insulation test implementation guidelines - arrester test. It can also be used for factory and acceptance test in laboratory. With RS-232 communication interface, data can be uploaded to the computer for processing.zhagunmj.37ix.com.cnqiangban.37ix.com.cnshengtaimu.37ix.com.cn 近年来，供电可靠性的要求使得氧化锌避雷器试验已由原来的停电预试为主转为带电测试为主，带电测试工作得到加强。氧化锌避雷器带电测试可以在无需停电的情况下，通过对避雷器阀片的泄漏电流中阻性分量的测量，判断避雷器阀片的老化和受潮情况，具有停电测量无可比拟的优势。 In recent years, the requirement of power supply reliability has changed the test of zinc oxide arrester from power cut preliminary test to live test, and the work of live test has been strengthened. The live test of zinc oxide arrester can judge the aging and dampness of the arrester valve by measuring the resistance component of the leakage current of the arrester valve without power cut, which has incomparable advantages in power cut measurement. |
