High-voltage motor repair detailed process
one. Winding high-voltage motor according to the voltage level need to use bisimine, monoimine, thin double wire and other specifications of the flat wire package, the material is available, the winding machine can be made into a shuttle into a circle, the general motor The shortest coil straight part of 25 cm, the maximum coil straight part of 1.2 meters, winding can be single flat winding, single winding, but also double-level transposition bit, but also double-level transposition vertical winding, determined according to specific requirements. Use the universal adjustment of the disc can also be wound round enameled wire coil. Winder built a speed motor and a turbine scroll reducer, driven winding machine to achieve 0-120 rev / min can be reverse rotation can be braked, and the positive and negative counts, generally around 1600KW Within a variety of motor coils, the other with a simple set of tensioner can control the tightness of the winding coil, the general repair shop to use the above products can, in case of special large-size specifications, you can choose a special type of winding equipment. two. Before the molding, wrap the high-voltage motor shuttle coil and wrap it with the shrinking tape and yellow wax ribbon. The purpose is to protect the outer insulation of the coil, the interlayer insulation and the insulation between the turns from being damaged. In the drawing machine from the mold fixtures, nose pins and other friction, to prevent loose deformation. Bandage coils generally use female workers, due to the clever work of women workers and work fast, generally 3-5 bandaged for pull type. You can also use the electric tape machine. three. Molding machine, up-type machine, drawing machine is actually a machine, its main purpose is to wind the winding machine winding bobbin-type or flat-wound bobbin-type coil into the coil, coil-type motor to the motor Stator core of the inner and outer circles as a standard, composed of radial to the heart of the coil, wound bobbin need to be technicians 2 people to complete, and pull (up) type generally takes 3 people. Before I had a machine, I had a handful of skilled craftsmen hand-pulled to shape 72 coils in 15 minutes, but it was a bit strenuous for larger coils. The use of drawing machine generally within an hour 3 people can pull out the standard 72 coils, each forming the linear part of the coil can be adjusted up to 1.5 meters, the height can be adjusted within 80 cm, the angle adjustment range of 0-60 Degree, four fixtures can achieve universal lock. General manufacturers, such as Harbin, a motor factory, Xiangtan Motor Factory, a subordinate factory more than a dozen to buy this manual after the pull machine, the overall evaluation is the production of seemingly simple, but the operation is flexible and convenient, the module, the mold Rapid, pull-type convenience, accurate positioning, diagonal alignment accurate, after all, a practical product. Drawing before the computer using the shape of the coil in accordance with the repair of the actual situation of the motor drawn into a map and made into a template used to adjust the drawing machine, drawing will not be the old coil as a template to adjust the general drawing machine, drawing machine four Clamp with adjustment mechanism up and down, adjust the clamping mechanism lock locking coil into the pull type program. My company produces electric pulling machine and Shanghai production is almost the same, they are about 90,000, I place for practical purposes, the electric pulling machine price of 25,000 yuan, hydraulic type of pulling machine price of 26,000 yuan. Molding machine in the country. Shanghai and Shenyang manufacturers do a good job, they make the mainframe to take into account the large generators, but the operation appears to be more cumbersome, mainly in the corner, move, adjust the distance, adjust the height, clip line, etc. are not flexible, more expensive .
