Composite potential clamp grading ring for electric reactor

Abstract

The invention relates to a composite potential clamp grading ring for an electric reactor. The composite potential clamp grading ring comprises a skeleton (1) formed when epoxy glass filaments are twined. The external surface of the skeleton (1) is provided with a semiconductor layer (2). The grading ring can be conveniently processed and simply and reliably structured; the twined filaments are made from insulated material and belong to an integral skeleton. Under the same voltage grade, the grading ring is lighter than aluminum grading rings; the semiconductor attaching material has magnetism and conductivity resisting properties and is conducting medium; when attached by semiconductor material, the grading surface is processed segment by segment; and eddy current loss due to excessive conductive area can be avoided. A shielding ring can be free of magnetic disturbance during the operation of electric reactor due to the material features; and extra heating sources can be avoided and overall performance of the electric reactor can be guaranteed.

Description

technical field [0001] The invention relates to a compound potential clamp voltage equalizing ring for reactors, which is applied to various reactors, and focuses on improving the electrical performance of equipment, reducing the influence of magnetic flux leakage on losses, reducing overall temperature rise, and improving shielding capabilities. Background technique [0002] At present, the reactors are all made of aluminum voltage equalizing rings, which are processed by rolling, welding, correcting, polishing and other processes on the master model with aluminum plates. During the operation of the reactor, a large magnetic flux leakage will be generated. Due to its metal characteristics, the aluminum grading ring will generate heat on the surface under the influence of the magnetic flux leakage. As a result, the heat source inside the reactor is uncontrolled, which increases the temperature rise limit and affects the overall performance of the reactor. There are two main...

Problems solved by technology

As a result, the internal heating source of the reactor is uncontrolled, which increases the temperature rise limit and affects the overall performance of the reactor.

There are two main disadvantages: 1) The closed structure increases the difficulty of manufacturing, the overall weight is high, and the auxiliary processing of metal molds is required, and the cost is high; 2) It will generate heat under magnetic flux leakage diffraction, resulting in additional loss and increased temperature rise
