Electric permanent magnet wiring structure, wiring method and excitation coil repairing method

Abstract

The invention discloses an electric permanent magnet wiring structure, a wiring method and an excitation coil repairing method. The wiring structure comprises a coil connector; the coil connector comprises an insulating shell and a conducting strip arranged in the insulating shell; a main line connecting area for containing a main line of an electro-permanent magnet and a coil connector area connected with an excitation coil of the electro-permanent magnet are arranged in the insulating shell; one end of the conducting strip extends to the main line connecting area to be connected with a mainline, and the other end extends to a coil joint area to be connected with a terminal of the excitation coil. The electric permanent magnet wiring structure has the advantages of being simple, practical, good in insulation performance, stable in connection effect, convenient to disassemble, assemble and maintain and the like; and the wiring method by using the wiring structure and the method for repairing a damaged excitation coil in the electric permanent magnet using the wiring structure have the advantages of rapidness and high efficiency.

Description

technical field [0001] The invention relates to the field of electro-permanent magnets, in particular to an electro-permanent magnet wiring structure, a wiring method and a method for repairing an excitation coil. Background technique [0002] The interior of the electro-permanent magnet is generally provided with a plurality of excitation coils, and each coil is connected to the main line in parallel or in series, and then connected to the electro-permanent magnet controller through the main line. Due to the wide range of application of the electro-permanent magnet, it is inevitable to be used in some humid, rainy and other occasions. It will cause the failure of the electro-permanent magnet or even damage the entire electro-permanent magnet. [0003] The existing wiring steps between the excitation coil and the main wire are usually to remove the insulation layer of the two main wires first, screw the two ends of the excitation coil to the two main wires respectively, and...

Due to the wide range of application of the electro-permanent magnet, it is inevitable to be used in some humid, rainy and other occasions. It will cause the failure of the electro-permanent magnet or even damage the entire electro-permanent magnet

[0003] The existing wiring steps between the excitation coil and the main wire are usually to first remove the insulation layer of the two main wires, screw the two ends of the excitation coil to the two main wires respectively, and then use an electric soldering iron to weld and fix the joint, and then use the insulation after fixing. Bandage the outer layer of the joint. This wiring process is very complicated and has high requirements for operators. When there are many excitation coils in the electropermanent magnet, each coil needs to perform this operation, and the workload is huge; in addition, the electropermanent The interior of the magnet is generally sealed with epoxy. When disassembling and repairing, it is necessary to destroy the epoxy sealing layer. The process is cumbersome and the workload is heavy, which is not conducive to repairing on the job site. Returning to the factory for repair will cause problems such as slowing down the construction progress.
