Abstract

The utility model relates to a high voltage fuse used in an underground transformer, consisting of an isolating plinth. A high voltage fusion tube cavity is arranged inside of the isolating plinth, and a sealing cover is arranged at one end of the isolating plinth while a lower contactor is arranged at the other end; a rotary cover is arranged on the external circumference of the sealing cover and connected with the isolating plinth through thread, and the external side of the middle section of the isolating plinth is embedded with an upper contactor. A high voltage fusion tube is arranged inside the high voltage fusion tube cavity, and one end of the high voltage fusion tube is connected with a rotary piece, while the other end is connected with the lower contactor. The external end of the rotary piece is connected with an internal handle which is arranged between the lower end of the sealing cover and the upper contactor, and a sealing ring is arranged between the sealing cover and the isolating plinth. Since the columnar high voltage fusion tube is arranged in the isolating plinth of the utility model and the contactors are arranged in the isolating plinth in an embedding manner, the sealing performance is good, and the utility model is applicable to underground transformer, meanwhile the high voltage fusion tube can be conveniently inserted in and pulled out for replacing.

Description

The high-tension fuse that is used for buried transformer

Technical field:

The utility model relates to field transformer, relates in particular to the fuse that is used for transformer, particularly a kind of high-tension fuse that is used for buried transformer.
