Abstract

The invention discloses an air-core reactor which comprises a light alloy shielding case, a basin-type insulator, a metal shell and a high-voltage coil unit. The metal shell comprises an upper shell and a lower shell which can be opened and closed, and the high-voltage coil unit comprises a fixing frame connected with the lower shell, an epoxy glass cloth insulating cylinder and a high-voltage coil. The air-core reactor has performance advantages of a small size, light weight, low cost, convenience in integrated design with other power equipment, convenience in transportation and the like. Andmeanwhile, the air-core reactor can achieve a voltage class of 100kV-1500kV and a current which is below 16A.

Description

technical field [0001] The invention relates to the technical field of reactors, in particular to an air-core reactor. Background technique [0002] At present, most of the existing air-core reactors use insulating rods as the keel, which are directly helically wound with wires and poured with epoxy resin or reserved for air cooling channels. The overall layered package structure is large in size and heavy in weight, especially for super large When the capacity of ultra / high voltage power equipment is high, multiple air-core reactors are required to be used together, which is very inconvenient to operate. [0003] On the other hand, the traditional air-core reactor is bulky and has no expansion interface, which is not convenient for integrated design with standard voltage transformers and other power equipment, which limits its application range. [0004] How to design a new reactor with small size, low cost and light weight, which can be integrated with standard voltage tr...
