Wang Zhengguo, deputy head of the electrical test class of the substation maintenance center of Binzhou Power Supply Company of Shandong Electric Power Company, member of the Communist Party of China, senior engineer and senior technician. He has successively won the titles of Outstanding Individual of Provincial Company Live Testing, Candidate of Provincial Company Young Talent Lifting Project, Pacesetter Individual of Shandong Province New Era Post Meritorious Labor Competition, "May Fourth" Outstanding Young Scientific and Technological Worker of Shandong Electrical Engineering Society, Binzhou Youth Academic and Technical Leader, Binzhou Craftsman, Chief Technician of Binzhou City, and Shandong May Day Labor Medal.
Rooted in the grassroots and dedicated to the power of youth. Wang Zheng will be down-to-earth and meticulous in his work as the code of conduct, and will study hard and analyze as technical requirements. Solid work in the city's more than 90 substations new equipment handover test, power outage equipment routine maintenance test, defective equipment diagnostic test, operating equipment live detection work. Participated in the State Grid Company's live detection skills competition and achieved excellent results, walked through dozens of 500kV and 1000kV substations in Shandong, Jiangsu, Liaoning, Henan, Jiangsu, Anhui, Gansu and other places, tested the location of partial discharge points, took infrared temperature measurement maps in tens of thousands of statistics, sufficient practical experience and solid theoretical learning, and grew into the company's system live detection experts, and repeatedly supported the defect consultation work of UHV substations in Anhui, Shanxi and other places as an expert representative of the provincial company. As the coach of the 2022-2023 provincial company's substation maintenance professional full core business ability improvement training camp, his team won the provincial company's 2022 full core business construction labor competition benchmark team, and the State Grid Company's 2022 equipment operation and inspection full business core team construction benchmark team.
Find the root cause and ensure the safety of your equipment. Wang Zheng has been working on live detection all year round, and has practiced the skills of judging internal defects in live detection of GIS equipment. By analyzing nanosecond differences with sensors, it is possible to accurately determine the defective parts of the equipment. In the work, a variety of technical means such as ultrasonic, ultra-high frequency, infrared temperature measurement, and ultraviolet corona detection are comprehensively used to do "physical examination" for the equipment. Through the accumulation of on-site experience, the GIS internal defect diagnosis method of acoustic-electrical-optical combination is summarized and refined, and the ultrasonic, ultra-high frequency partial discharge technology and X-ray imaging technology are combined to make the internal discharge position of the equipment can be quickly located, and the internal structure of the GIS enclosed equipment can be visualized in the station. The equipment fault diagnosis method based on the comprehensive diagnosis of a variety of tests was proposed, and hundreds of defects of live operation equipment were found successively, and a number of major equipment defects were successfully disposed of, saving nearly 10 million yuan worth of equipment assets. In the past three years, major defects in equipment have been found four times, and they have been commended and rewarded by the provincial company.
Keep integrity and innovation, and improve work effectiveness. Wang Zheng based on his own post innovation and efficiency, take the initiative to explore the direction of technological innovation, in-depth research on new problems and new technologies in the actual production, the team has won the State Grid Corporation advanced team, the provincial company "benchmark team", "Shandong Province quality trustworthy team", Binzhou City Worker Pioneer, State Grid Shandong Electric Power Company Worker Pioneer. He served as a part-time trainer of the provincial company, and developed the course "Internal Partial Discharge Signal Type Identification and Positioning Analysis of GIS Equipment" which was selected into the excellent course resource library of the provincial company. The innovative achievement "Development of Insulating Oil Gas Automatic Switcher" won the first prize of Shandong Province Excellent Quality Management Achievement, and the device saved a total of more than 80 yuan per year; "Transformer Insulating Oil Chromatography Analysis Test Injection Auxiliary Device" won the first prize of the Provincial Company's Excellent Quality Management Achievement, the second prize of Shandong Electric Power Employee Technical Achievement, and the second prize of Shandong Province's Excellent Quality Management Achievement, and the results were selected as the provincial company's key entrepreneurship and innovation incubation project in 2022, and the device saved a total of more than 40 yuan in test costs every year; "Development of Oil Sampling Auxiliary Device for Transformer On-load Tap-Changer" won the second prize of excellent quality management achievements of the provincial company; "Transformer On-load Switch Fast Switcher" won the third prize of Shandong Province Excellent Quality Management Achievement; "Transformer hemodialysis manipulator-oil chromatography test automatic sampler" won the bronze medal of the provincial company youth innovation and creativity competition; "Handcart Circuit Breaker Circuit Resistance Test Clip" was awarded the "Top 10" Technological Innovation Achievement of the Provincial Company's Operation and Inspection Major. Authorized 1 national invention patent, 14 utility model patents, published 2 Chinese core journal papers, and more than 10 national journal papers.
