In April 2020, as the prelude to the “War Epidemic” of resuming work and production, Xinsheng Energy responded to the requirements of the Hubei Provincial Headquarters for Fighting the Epidemic, and the tasks of strict epidemic prevention and scientific resumption of work began to be carried out in an orderly manner. On April 27, 2020, a 9-person technical team consisting of our technicians went to Huanggang, Hubei, to provide technical services for the expansion project of the main transformer 500 kV substation in Daji, and fired the first shot of the 2020 resumption of work and production.
The project has a special time schedule. The crossbows to fight the epidemic have not been put down, but the magazines for resuming work and production have been loaded. In the face of the originally complex expansion project, the implementation during the epidemic prevention period is a double test of the professional quality and physical fitness of the technical service personnel. However, our technicians are not afraid of challenges and always abide by the operation requirements, taking everyone as the benchmark for the operation. In strict accordance with GB50150-2016 "Electrical Equipment Installation Engineering Electrical Equipment Handover Test Standard" and the requirements of the customer unit, the tasks delivered by the customer were completed on time and with high quality. The service content includes continuous current measurement under continuous operating voltage of 500kV/220kV metal oxide arrester; 220kV pillar insulator 5-pillar pillar insulator flaw detection test; 500kV/220kV/35kV transformer partial discharge withstand voltage test; completion of partial discharge test for 12 sets of 220kV transformers ;500kV/220kV SF6 circuit breaker withstand voltage test; 500kV substation grounding down conductor and grounding grid conduction test; 35kV capacitor rated voltage impulse closing test; 500kV transformer insulating oil bottle sampling, oil dielectric loss factor measurement, oil water solubility Acid value (PH) test, oil breakdown voltage test, oil acid value test, oil closed flash point test, oil moisture (moisture) test, oil chromatographic analysis test, gas analysis test in oil; SF6 gas sampling, leak detection , Dew point test and other technical services.
In order to ensure the realization of the two successful principles of epidemic prevention and resumption of production, our technical team has conducted repeated studies on the expansion project of the 500 kV substation of the Daji main transformer, combined with local epidemic prevention requirements and the on-site operation of the substation, taking into account epidemic prevention and control, resumption of work and production, To ensure safety related requirements, a set of technical service programs with strong operability and high safety are specified. "Only by putting the preparatory work in the front, can we achieve the mission goal without fail", the leader of our technical team repeatedly emphasized when communicating with the customer's project leader. Finally, through the acceptance of the project department supervisor and the person in charge of the customer, they unanimously agreed that the technical service of the "Daji Main Transformer 500kV Substation Expansion Project" was qualified!
Wuhan Xinshengneng Technology Co., Ltd. has fully resumed work and production. With the arrival of spring inspection and summer electricity peaks, our company will continue to serve the power grid and help ensure electricity!
