Secondary circuit wire straightening and cutting tool

Abstract

The invention relates to a tool for straightening and cutting secondary circuit conductors, which is special in that it has a housing, the housing is composed of upper and lower housings that are folded and closed by hinges, and inside the housing are arranged Two pairs of rolls located in the same vertical plane, each pair of rolls is composed of upper and lower rolls respectively fixed in the upper and lower casings by means of rotating shafts, the upper and lower rolls are fitted on their peripheral surfaces and correspondingly equipped with multiple The housing is provided with a wire inlet and a wire outlet corresponding to the positions of the wire grooves, and the position of the wire outlet is provided with a shearing device. The utility model has the advantages of simple structure, convenient use, significantly improved maintenance efficiency, and will not cause damage to the outer insulation layer of the wire.

Description

technical field [0001] The invention relates to an auxiliary tool in the wiring process of secondary loop conductors, in particular to a straightening and cutting tool for secondary loop conductors. Background technique [0002] Power equipment circuit breakers, isolating switches, etc. have electric operating mechanisms, and the mechanism box is full of wires used in the secondary circuit. When the equipment has a fault in the secondary circuit, it is usually necessary to check a part of the wires. To replace the damaged wires, the layout and direction of the original wires will often be broken after the replacement. Repeated occurrences of similar situations will cause confusion in the cable connections in the mechanism box, causing unnecessary trouble for finding faults, and it is possible to connect wires during the wiring process. If the wrong contact is connected, it will cause failures such as lack of phase or reverse rotation of the equipment, which has become a hidd...

[0002] Power equipment circuit breakers, isolating switches, etc. have electric operating mechanisms, and the mechanism box is full of wires used in the secondary circuit. When the equipment has a fault in the secondary circuit, it is usually necessary to check a part of the wires. To replace the damaged wires, the layout and direction of the original wires will often be broken after the replacement. Repeated occurrences of similar situations will cause confusion in the cable connections in the mechanism box, causing unnecessary trouble for finding faults, and it is possible to connect wires during the wiring process. If the wrong contact is connected, it will cause failures such as lack of phase or reverse rotation of the equipment, which has become a hidden danger that undermines the stability of the power system.

In order to avoid this phenomenon and shorten troubleshooting time, on-site personnel often have to straighten the wires before wiring. In the process of straightening the wires, they mainly use the method of one drop and two pulls. The insulation layer has a lot of damage, and it may cause the wire to break, especially in the case of low temperature, this method will no longer be feasible, which will bring difficulties to winter operation
