Secondary circuit wire straightener

Abstract

A secondary circuit conductor straightener is characterized in that the straightener comprises a housing, the housing is composed of upper and lower housings folded and closed through hinges, two pairs of rolls in a same vertical plane are disposed inside the housing, each pair of rolls includes upper and lower rolls fixed inside the upper and lower housings through rotating shafts respectively, the upper and lower rolls fit peripherally and are provided with a plurality of corresponding slots, and the housing is provided with a conductor inlet and a conductor outlet corresponding to the slots. The secondary circuit conductor straighter is simple in structure and convenient to use, maintenance efficiency can be improved significantly, and no damage is caused to the outer insulating layer of each conductor.

Description

technical field [0001] The invention relates to an auxiliary tool in the wiring process of secondary loop wires, in particular to a secondary loop wire straightener. 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 hidden danger that undermines the sta...

[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
