Abstract
The utility model relates to an insulation end fastener for an electric machine, which is manufactured via insulation material by one time wet process. The utility model is characterized in that the cross section of an insulation circular fastener with a hollow circle stopper is an L shape. The end fastener not only can be used for fixing a compensation winding of a stator on the radial direction of the motor but also can be used for preventing the compensation winding deforming on the motor shaft, which effectively solves the problem of the short circuit fault and the burning fault between a main pole and the compensation winding. Due to the fact that in all failures of the ZQ650-1 type pulling electric motor, more than 70 percents failure is created by the short circuit fault and the burning fault, the insulation end fastener for an electric machine means that more than 70 percents failure can be reduced for the ZQ650-1 type pulling electric motor.
Description
Electrical machine insulation end hoop is a motor stator compensation winding insulation fixture.
Motor side hoop in the past, adopting the cross section is the steel support ring in garden, is tied with no latitude insulating tape on the steel support ring.This scheme owing to vibrate in the machine operation process, is ground away the no latitude insulating tape that is wrapped on the steel support ring on the one hand, loses insulation property; On the other hand because the steel support ring in cross section, garden, can only be along motor fixed stator compensation winding radially, and can not stop the distortion of motor nose balance winding, cause short circuit over-heated fault between main pole and compensation winding easily like this.According to investigations, in whole faults of ZQ650-1 type traction electric machine, be to cause more than 70% by above-mentioned reason.
The purpose of this utility model provides a kind ofly to be made by insulating material, the cross section is the electrical machine insulation end hoop of " L " shape, making can be along the motor compensation winding of fixed stator radially, again can be at motor shaft to stoping the compensation winding deformation, effectively solve short circuit over-heated fault between main pole and compensation winding, ensure that locomotive is at railway operation safety.
Above-mentioned purpose is achieved like this, with epoxy glass fiber on shaper once wet method make garden hoop with hollow garden retaining head, this hoop cross section, insulation garden is " L " shape, through the hot setting moulding, makes the insulating end hoop of motor.
This motor side hoop good insulation preformance even at high temperature still have favorable mechanical performance and insulation property, also can be made into H level product; This cross section is the motor side hoop of " L " shape, can be at the motor compensation winding of fixed stator radially, simultaneously at motor shaft to stoping the compensation winding deformation.Therefore can effectively solve short circuit over-heated fault between main pole and compensation winding.This just means no longer taking place more than 70% of original fault concerning ZQ650-1 type traction electric machine.
Fig. 1 is the schematic diagram of electrical machine insulation end hoop embodiment, and Fig. 2 is the sectional view of Fig. 1.
Embodiment, soak with modified epoxy with the non-twist electrical glass fiber roving of alkali-free, through drawing continuous winding, roll extrusion on the mould of typing, a wet method is made with the garden of hollow garden retaining head and is bound round, after cure the processing moulding, the motor side hoop is made for " L " shape in its cross section.
