Description

Technical Field

[0001] The invention relates to an air-core reactor, in particular to a high-stability lightweight dry-type air-core reactor, and belongs to the technical field of air-core reactors. Background Art

[0002] The hollow reactor in the prior art is wrapped with glass fiber during the production process. The winding method of the glass fiber is determined according to the design requirements of the hollow reactor, such as spiral winding, flat winding, and flower winding. The common method is to first wind the coil surface of the reactor in a spiral manner with a spacing less than the width of the fiber tape to form a flat winding layer of the fiber bundle, and then reciprocate from one end to the other end on the surface of the flat winding layer in a spiral manner with a spacing greater than the width of the fiber tape to form a flower winding layer of the fiber bundle. The winding is started to implement the winding. The glass fiber after impregnation is evenly and tightly wound on the coil or core of the hollow reactor according to a predetermined winding method and parameters. During the winding process, the winding tension, speed and number of layers must be controlled to ensure the winding quality of the glass fiber. The hollow reactor wrapped with glass fiber is placed in a curing furnace. According to the curing process requirements of the resin system, the curing temperature, time and heating rate and other parameters are controlled to cure the resin and firmly bond the glass fibers together to form a wrapping layer with certain strength and insulation properties.

[0003] However, the winding method has good sealing performance, which also leads to extremely poor heat dissipation. Heat dissipation of reactors has always been a problem. Therefore, a high-stability and lightweight dry-type air-core reactor is designed to solve the above problem. Summary of the invention
