Abstract

A 10KV high-voltage motor forming coil and a processing method thereof, relating to a high-voltage motor forming coil and a processing method thereof. Domestically mature and reliable 10KV (F-class) high-voltage motor forming coils have a single-side insulation thickness of 2.52mm. The coil of the present invention is shuttle-shaped, including two ends and a straight part, which includes a plurality of copper flat wires wrapped by insulating materials, a mica insulating layer wrapped in a plurality of copper flat wires, and a semiconductor dielectric layer wrapped in a mica insulating layer. It is characterized in that: the mica insulating layer is formed by winding 3 to 7 layers of mica insulating tape with less glue composition in a semi-folded manner, and the thickness of the mica insulating layer is ≤ 2.4mm; the mica insulating layer, the semiconductor dielectric layer Constitute the main insulating layer of the coil, the semi-conductive dielectric tape is outsourced on the outer mica insulating layer in a half-folded manner to form a semi-conductive layer, the thickness of the main insulating layer of the coil is ≤ 2.5mm; the straight part of the coil is immersed in resin. The purpose of the technical solution is to reduce the volume of the motor and the manufacturing cost.

Description

technical field [0001] The invention relates to a forming coil of a high-voltage motor and a processing method thereof, in particular to a forming coil of a 10KV high-voltage motor and a processing method thereof. Background technique [0002] Domestically mature and reliable 10KV (Class F) high-voltage motors form a single-sided insulation thickness of 2.52mm. Some motor manufacturers are limited by the design of the insulation structure. The single-sided insulation thickness of the coil may reach about 2.8mm. As we all know, the future development direction of motors is small size, high power and high efficiency. The power of the motor increases with the increase of the slot utilization rate; the volume of the motor decreases with the increase of the slot utilization rate; the efficiency of the motor increases with the increase of the slot utilization rate. Therefore, how to improve the utilization rate of motor slots has become the focus of research by motor manufacturer...
