Abstract

The invention discloses a reduction insulation structure suitable for a high-voltage motor and an insulation processing method thereof. The reduction insulation structure comprises a plurality of low resin mica tapes (2) lapped outside an electromagnetic coil (1), and is characterized in that vacuum dipping treatment is carried out by utilizing vacuum pressure dipping resin after the low resin mica tape is lapped, and the insulation structure with reduced insulation thickness is formed after baking and curing. The breakdown voltage of the insulation structure is qualified, the normal dielectric loss, the thermal state dielectric loss, the dielectric loss increment and the electrical strength of the insulation structure reach high grade.

Description

technical field [0001] The invention belongs to the technical field of motor insulation, and in particular relates to a thinned insulation structure suitable for high-voltage motors and an insulation treatment method thereof. Background technique [0002] In order to operate the motor reliably, it is necessary to use insulating materials to insulate the live parts, and the service life of the insulating materials has a great relationship with the insulation level of the material itself and the operating temperature. As an energy or signal conversion element, the motor itself has energy loss during operation, and part of the energy loss causes its own temperature to rise. High-voltage motors are divided into generators and motors. With the increase of power generation capacity, generators are getting bigger and bigger, and the technical requirements for generators are getting higher and higher. The technological development of large-capacity generators has also driven the dev...
