Abstract
The utility model provides a hanging 35kV double-contact lightning arrester. The lightning arrester comprises an outlet terminal, an insulator, a 35kV lightning arrester body, and a grounding support. The outlet terminal is connected to the upper end of the 35kV lightning arrester body by a double-contact connector. The grounding support is connected to the lower end of the 35kV lightning arrester body by a hook assembly. The hook assembly comprises a hook, a flippable metal plate, a grounding contact, and an auxiliary installation bolt. A thermal-explosive disconnector is fixedly installed at one end of the flippable metal plate by means of the auxiliary installation bolt. The thermal-explosive disconnector is connected to the 35kV lightning arrester body via a tinned silver flexible cord. Compared with the prior art, the lightning arrester provided by the utility model solves the problems of easy loosening and arcing of wedge contacts of hanging lightning arresters. As a result, the hanging lightning arrester can be used for a 35kV high voltage line, live rotation and maintenance of the lightning arrester can be performed, stable operation is achieved, and the safe operation efficiency of an electrical network is substantially improved.
