A Generator Conductive Screw Insulation Wrapping Device

Abstract

The invention provides an insulation lapping device for a conductive lever of an electric generator. The insulation lapping device is characterized by comprising a lathe bed, wherein the lathe bed is provided with a lapping head and an ejector pin, the conductive lever of the electric generator is arranged between the lapping head and the ejector pin, the lapping head can be driven by a driving device so as to drive the conductive lever of the electric generator to rotate, the lathe bed is also provided with an insulation material tension device and an insulation material heating device, the insulation material heating device comprises an air outlet, the insulation material tension device is in front of or behind the part of the conductive lever of the electric generator to be insulated and lapped, and the air outlet of the insulation material heating device is above the part to be insulated and lapped. The insulation lapping device can prevent phenomena of uneven tension and uneven temperature in insulation lapping of the conductive lever; and the processed conductive lever has good insulation and electrical performances and high airtightness; and problems of poor electric withstand voltage performance, short circuit and poor airtightness in insulation of the conductive lever are solved.

Description

technical field [0001] The invention relates to an insulation wrapping device for conductive screws of generators, which is suitable for the fields of conductive screws of various grades of steam turbine generators, insulation wrapping of radial screws, and insulation dimension processing. Background technique [0002] The conductive screw is the part connecting the rotor coil and the axial lead wire in the turbo generator. The working current of the conductive screw is as high as thousands of amperes during operation, and the excitation current of the generator with more than one million is as high as nearly 10,000 amperes. The highest voltage that the conductive screw bears when the turbo generator is started is close to 5000 volts. In the system where the generator rotor is cooled by hydrogen gas, the conductive screw must also withstand the hydrogen pressure of 0.5 MPa, and there must be no leakage. The technical requirements of the conductive screw are very high. , is o...

AI Technical Summary

Problems solved by technology

The labor intensity of the operator of this conductive screw insulation wrapping equipment is high, and the insulation quality of the wrapping fluctuates greatly. The quality index after the screw insulation wrap is cured leads to the phenomenon that the electrical withstand voltage performance or airtight performance of the conductive screw insulation is unqualified
