Terminal short-circuit device

Abstract

The invention relates to a terminal short-circuit device which comprises a plurality of short-circuit devices, each short-circuit device comprises a connector, a first wire, a take-up reel and a first connecting piece, the connector is used for connecting a terminal, one end of the first wire is connected with the connector, the other end of the first wire is connected with the take-up reel, and the take-up reel is electrically conducted with the first connecting piece. Every two adjacent short circuit devices are detachably connected through two first connecting pieces, and the take-up reel can recycle the first wire into the take-up reel. According to the terminal short-circuit device, the number of short-circuit devices can be spliced according to needs, so that the terminal short-circuit device has high applicability. In addition, after the operation is finished, the terminal short-circuit device can recycle the first wire into the take-up reel, and the situation that the detection efficiency is reduced due to the fact that the first wire between multiple short-circuit devices is wound is avoided.

Description

technical field [0001] The invention relates to the technical field of power equipment, and in particular, to a terminal shorting device. Background technique [0002] In the operation, maintenance and experimental operation of the power system, in order to ensure the normal operation of the power equipment, it is necessary to short-circuit the terminals of the equipment. At present, there are two main ways of shorting: one is to short the terminals through a shorting piece, the shorting piece will be set in multiple shorting slots, and multiple terminals on the device will be clamped in the shorting slot. , so that multiple terminals can be short-circuited, but due to the different terminal sizes of different devices and the different spacing between terminals, so that different types of devices need to use short-circuit pieces of different specifications, so the short-circuit piece of this method The applicability is low and the cost is high; the other is to use copper wi...

At present, there are two main ways of shorting: one is to short-circuit the terminals through the shorting piece, the shorting piece will be set in multiple shorting slots, and multiple terminals on the device will be stuck in the shorting slots , so that multiple terminals can be short-circuited, but because the size of the terminals of different devices and the spacing between the terminals are different, so that different types of equipment need to use different specifications of the short-circuit bar, so the short-circuit bar of this method The applicability is low and the cost is high; the other is to use copper wires to short-circuit the terminals. This method needs to peel off the outer skin of the copper wires to expose the metal wires, and then wind the metal wires on the terminals and use the screw lock tight, the shorting process is cumbersome, and there may be a weak connection between the metal wire and the terminal, resulting in a false connection
