Abstract

The invention discloses a handle of an oil-immersed fuse. The handle has the functions of moving timely and triggering a signal output device when the fuse moves. 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. The pull rod comprises a large cylindrical head and a large connecting rod, the linkage mechanism comprises a small connecting rod, a front limiting screw and a rear limiting screw, the front end and the rear end of the small connecting rod are respectively provided with a flange on the radial side, the thickness of each flange is smaller than the width of a groove in the large connecting rod, the two flanges are respectively and axially provided with a thread through hole, the small connecting rod is arranged parallel with the large connecting rod in an axial moving mode, the screw head of the front limiting screw is located in a front inner hole of the large cylindrical head, the rod portion of the front limiting screw is inserted in a rear inner hole of the large cylindrical head in a movable mode and is in threaded connection with the thread through hole of the flange at the front end of the small connecting rod, the screw head of the rear limiting screw is located in a middle inner hole in handle body and in a middle inner hole of the sealing cover, and the rod portion of the rear limiting screw is inserted into a front inner hole of the handle and in a front inner hole of the sealing cover in a movable mode and is in threaded connection with the thread through hole of the flange at the rear end of the small connecting rod.

Description

technical field [0001] The invention relates to a handle for an oil-immersed fuse. Background technique [0002] Oil-immersed high-voltage fuses are widely used in wind power generation systems. The monitoring station of the wind power generation system is generally far away from the wind field. Generally, the oil-immersed fuse has no signal output after operation, so that the monitoring station of the wind power generation system cannot detect and disconnect the three-phase circuit in time, causing the circuit to run without phase. , increasing security risks and maintenance costs. In addition, oil-immersed high-voltage fuses have extremely high requirements for oil tightness. During long-term use, no oil is allowed inside the fuse, otherwise explosion and serious fire may occur when the fuse operates. Contents of the invention [0003] The purpose of the present invention is to overcome the defects of the prior art, and provide a handle for oil-immersed fuses, which h...
