Abstract
Description
Technical Field
[0001] This utility model relates to the field of three-phase power transmission, and in particular to a three-phase common GIL bus temperature rise and withstand voltage joint control platform. Background Technology
[0002] Traditional three-phase power transmission uses a set of three parallel conduit busbars arranged vertically. Each busbar contains a conductor concentric with the outer casing, and each section is supported by a set of insulators. The testing methods for this structure are relatively mature, generally employing separate voltage and current tests. That is, the current carrying capacity is low during AC withstand voltage tests, and the voltage is low during high current temperature rise tests. This structural type also has sufficient structural margin. With the advancement of technology, a three-phase integrated GIL structure has emerged. This structure can significantly reduce the tunnel space size and the manufacturing cost of the busbars. However, it is not convenient to control the operation during temperature rise and withstand voltage tests, and it is difficult to fully simulate the actual use conditions. Therefore, we propose a three-phase integrated GIL busbar temperature rise and withstand voltage joint control platform to solve the above problems. Utility Model Content
