Abstract: After differential pressure protection action, this paper analyzed the electrical and oil tests of the assembled capacitors, and dismantled and studied on its noumenon. The fault was due to the false wiring in the installation process, so as to lead to the wire overheating and gradually fusing, which caused the primary differential pressure and protection tripping. Analysis was made to the action condition of differential pressure protection. This paper gave suggestions of searching this type of faults to provide references for manufacturers and maintenance personnel.
Key words: assembling; capacitor; differential pressure protection; accident analysis
