Anti-corona treatment device for winding coil of high-voltage winding 6kV voltage-level motor

Abstract

The invention relates to an anti-corona treatment device for a winding coil of a high-voltage winding 6kV voltage-level motor. The anti-corona treatment device comprises a device whole body; a bobbinplacement seat is fixedly connected below the left side of the front surface of the device whole body, and a high-resistance coating device is arranged on the front surface of the device whole body and located at the upper right 45-degree position of the bobbin placement seat. According to the device, a single-strand copper wire is independently processed; in the whole transmission belt flow, high-resistance paint spraying on the end part is realized; insulation treatment is carried out on the middle part of the copper wire; through overflow of such operation, the problems that an existing copper wire needs to be treated twice, the difficulty is large, the manual operation cost is high, and the production efficiency is low can be solved; after coating spraying, rapid drying treatment can be conducted; a shearing mechanism is arranged, and thus the copper wire can be subjected to segmented treatment; the whole anti-corona operation is completed in extreme time; and the treatment efficiency and quality of the coil are greatly improved.

Description

technical field [0001] The invention relates to the technical field of anti-corona treatment devices, in particular to an anti-corona treatment device for high-voltage winding 6kV voltage level motor winding coils. Background technique [0002] At both ends of the high-voltage winding without anti-corona treatment, the leakage current on the surface of the winding coil end increases from the nose to the slot of the stator core, so the voltage drop on the insulating surface at the exit of the slot is the largest, and the axial field Strong is also the highest. This is also the most important part of the main insulation and anti-corona treatment. The high-voltage winding 6kV voltage level motor winding coil is already in the critical state of corona. Therefore, the national explosion-proof standard stipulates that winding coils with a voltage level of 6kV and above must be protected against corona. [0003] The existing anti-corona treatment method is mainly to standardize ...

Problems solved by technology

[0003] The existing anti-corona treatment method is mainly to standardize the coils, that is, cut the wires to form a bundle, and then bundle them for dressing. The disadvantage of this is that the coils in the bundle are mutually incompatible during the anti-corona treatment and insulation treatment. The bundled coils cannot be completely coated, and the effect is not obvious when used. More importantly, there are many processing steps, which increases the overall processing cost and reduces the efficiency.
