Abstract

The invention discloses an insulation structure of a high-voltage motor in the field of high-voltage motor insulation, which includes coil insulation, slot insulation and integral insulation. The coil insulation includes conductor insulation and end insulation. The insulation is a round copper wire wrapped with polyimide-F46 composite film and sintered as a whole as a conductor. The invention can effectively solve the problems that the existing insulation technology cannot meet the insulation requirements of the 10000V high-voltage motor conductor, and there are dangerous situations such as discharge during use.

Description

technical field [0001] The invention relates to the field of high-voltage motor insulation, in particular to an insulation structure of a high-voltage motor. Background technique [0002] The insulation system is an important part of the motor, and its performance and state determine the safety and life of the motor in operation. The voltage of conventional high-voltage motors is 3000V, 6000V, 10000V, etc. The current conventional high-voltage insulation system can meet the requirements of general high-voltage motors, but for high-voltage motors with special requirements (high frequency, high voltage, vacuum, special environment, electrical parameters, etc.) There are insurmountable problems with conventional high voltage insulation systems. Unable to meet its insulation requirements, corona, local breakdown discharge and other phenomena often occur. The thermal effect of corona, the oxides of ozone and helium, etc., will increase the local temperature inside the coil, resu...
