TESTING METHOD FOR DOUBLE-FRACTURE BUSBAR DISCONNECTOR IN 220-KILOVOLT POWER TRANSFORMATION COMBINED ELECTRICAL DEVICE

摘要

Disclosed is a testing method for a double-fracture busbar disconnector in a 220-kilovolt power transformation combined electrical device. A first busbar and a second busbar are comprised, wherein the first busbar is connected to a first end of a first double-fracture disconnector of a double-fracture busbar disconnector, the second bus is connected to a first end of a second double-fracture disconnector of the double-fracture busbar disconnector, and a second end of the first double-fracture disconnector is connected to a second end of the second double-fracture disconnector; and the testing of the double-fracture busbar disconnector comprises: closing one double-fracture disconnector in the double-fracture busbar disconnector, respectively applying a voltage to the first busbar and the second busbar, respectively testing two ends of the other double-fracture disconnector which is not closed, then exchanging the opening and closing relationships of the double-fracture disconnectors, and repeating the voltage applying process, thereby completing the testing of the double-fracture busbar disconnector.
