The day before yesterday, South Network Ultra High Voltage Company held in Guangzhou, "UHVDC equipment preventive testing of new technologies and test methods without stitching application" scientific and technological achievements appraisal. The expert panel headed by Wu Zhirong, chief expert of State Grid Electric Power Research Institute, unanimously considered that the project has made a number of innovative research results, which have reached the international advanced level in general. The DC equipment is not disconnected, the DC arrester charged detection and direct current Through-wall bushing current-carrying structure contact state diagnostic technology has reached the international advanced level. South Network ultra-high pressure The results mainly focus on the insufficiency of project pre-test of UHVDC equipment, the difficulty of on-site implementation and the low efficiency of pre-test. The author puts forward the research on the detection of DC arrester live load, contact state diagnosis of DC bushing current-carrying structure, The new method of preventive test for DC equipment was developed and the test equipment was developed. The test methods of leakage current detection, DC pole parameter test and so on were optimized and corresponding test equipment was improved. The research results have improved the pre-test items and test methods for UHV DC equipment, effectively solved the problems of some existing test equipment, such as inaccurate measurement and undetectable problems, and improved the accuracy of test data, forming the industry standard and enterprise standard of 1 Items, 5 invention patents, 10 utility model patents and 9 high-level academic papers. It is reported that the research results have been successfully applied to the preventive test of UHV DC engineering equipment such as Yun Guang and Nuozhadu and effectively enhanced the on-site testing of UHV DC equipment and achieved good economic and social benefits.
