Abstract

The invention discloses an oil-immersed high-voltage fuse comprising a base, a fuse carrier, a fusing element, an impactor and a signal output device, wherein the fuse carrier and the fusing element are arranged in the base. The base comprises an outer shell and two conductive rings. The fusing element comprises a fuse tube, a front connecting cap, a rear connecting cap, a framework arranged in the fuse tube, a main fuse body winding the framework and an auxiliary fuse body in parallel connection with the main fuse body. The fuse carrier comprises a handle and two electrically contact couplers. The handle comprises a handle body, a sealing cover, a pull rod and a linkage mechanism, wherein the handle body, the sealing cover, the pull rod and the linkage mechanism are sequentially connected, and the linkage mechanism can be connected with the front end of the sealing cover in a vertically movable mode and is parallel with the pull rod. The impactor is arranged in the rear connecting cap of the fusing element and is connected with the auxiliary fuse body. The signal output device is arranged at the rear end of the handle. After the fusing element moves, the impactor is ejected and pushes the linkage mechanism to move backward, so that the linkage mechanism triggers the signal output device to send a fusing signal. Therefore, people in a wind power generation monitoring station can eliminate faults timely, and maintenance of wind power generation is facilitated.

Description

technical field [0001] The invention relates to an oil-immersed high-voltage fuse. Background technique [0002] At present, American box-type transformers are widely used in wind power generation systems because of their compact structure and low price. Oil-immersed high-voltage fuses are mainly used in American box-type transformers. With the development of wind power generation, reducing maintenance costs and remote monitoring are becoming more and more important. But after the fuse adopted on the existing wind power generation system moves, the monitoring station of the wind power generation system cannot know where the problem of the fault goes out in time, so the elimination of the fault has increased great difficulty and inconvenience. Contents of the invention [0003] The purpose of the present invention is to overcome the defects of the prior art, and provide an oil-immersed high-voltage fuse, which can output signals in time when the fuse operates, so that the...
