Signal output device used for oil fuse

Abstract

The invention discloses a signal output device used for an oil fuse. The signal output device used for the oil fuse comprises a switch cover, a micro switch, a rapid plug connector and an amphenol connector, wherein the switch cover comprises a cover board, an outer ring connected to the front end face of the cover board and a switch groove connected to the front end face of the cover board and located in the outer ring; the cover board of the switch cover is provided with a cable penetrating hole communicated with the switch groove; the micro switch is installed in the switch groove of the switch cover in the mode that a contact operation handle of the micro switch faces forwards and is fixed and sealed in the switch groove of the switch cover through epoxy glue; the rapid plug connector and the amphenol connector are arranged outside a base; the rapid plug connector is composed of a plug and a socket. The signal output device is simple in structure and convenient to assemble and disassemble, can provide signal output after the fuse moves, prevents phase-deficient operation of a circuit and lowers safety risk.

Description

technical field [0001] The invention relates to a signal output device for an oil-immersed fuse. Background technique [0002] At present, oil-immersed fuses are mainly used for the protection of wind power generation devices, but because they have no signal output function, and the monitoring station of wind power generation devices is far away from the wind field, they cannot get feedback in time after the fuse operates, resulting in circuit failure. The open-phase operation of wind turbines will cause safety risks, and it will also cause difficulties in the maintenance of wind power generation devices. Nowadays, the society has higher and higher requirements for intelligence, so it is particularly important to develop a signal output device suitable for oil-immersed fuses, which is of great help to the maintenance of wind power generation devices, the reduction of safety risks and the determination of faults . [0003] Moreover, after the existing signal output device i...

Problems solved by technology

[0003] Moreover, after the existing signal output device is installed on the fuse, the anti-fog and moisture-proof performance is not strong, and it is not suitable for use in poor environments. When disassembling, it needs to be removed together with the fuse-carrying part of the fuse, which is inconvenient to use.
