Core Viewpoint - The successful replacement of high-voltage capacitor conductive rods at the 500 kV Shuozhou Substation enhances the safety and reliability of the power grid in Shanxi, particularly for the "West-to-East Power Transmission" project [1][5]. Group 1: Project Overview - The maintenance work at the 500 kV Shuozhou Substation took place from September 12 to September 28, involving the inspection of 10 primary devices and 13 protection devices, as well as the replacement of high-voltage capacitor conductive rods and upgrades to protection devices [1]. - The project utilized three oil filter machines, three vacuum pumps, and three special vehicles, with over 50 personnel involved in the operations [1]. Group 2: Technical Details - The high-voltage capacitor conductive rod is critical for the safety of the power line; replacing the original three-segment conductive rod with a seamless single rod significantly reduces potential safety hazards [1]. - The replacement process included detailed safety checks, such as ensuring the internal gas composition of the high-voltage capacitor met safety standards before personnel could enter [3][4]. Group 3: Testing and Results - The final assessment on September 28 included long-duration induced voltage tests and neutral point AC voltage tests, marking the first such tests for 500 kV capacitors in the province [5]. - All test results were within acceptable ranges, confirming the equipment's readiness for operation and ensuring the stability of the "West-to-East Power Transmission" corridor [5].
