Problems solved by technology

The dry-type air-core reactors currently used in power systems are usually still closed products, which are characterized by the use of multi-layer insulated wires closely wound, so the volume is small; the disadvantage is that there is a large difference between the temperature coefficient of the metal wire and the insulating material. The difference is that when the product is running online, it is very easy to have surface chapping, dirt absorption, and even dendritic discharge at the end of the ring body. In addition, the noise is large and the product interchangeability is poor.

Abstract

A frame type dry hollow controlled reactor is formed by an inductance coil, an upper hanging bracket, a lower hanging bracket and a controlled adjusting device, wherein the inductance coil adopts insulting rack groups which are evenly distributed along the circumferential direction, the insulating rack groups, the upper hanging bracket and the lower hanging bracket are meshed and fixed in insulation through structural press plates, and are integrated through fastening belts, and the upper hanging bracket and the lower hanging bracket are fixed through an insulating draw plate and a fastening belt. The controlled device is formed by a regulating coil and a connecting sleeve, wherein the regulating coil is provided with a regulating terminal, and the regulating terminal and the connecting sleeve can form the circuit connection of the regulating coil and the inductance coil. The invention has the advantages of excellent structural stability, high mechanical strength, and favorable heat radiating property, controllable inductance and convenient regulation.

Description

(1) Technical field [0001] The invention belongs to the field of reactors, in particular to a frame-type dry-type hollow controllable reactor. (2) Background technology [0002] In the power system, the reactor plays a very important role in improving the quality of the power grid and ensuring the safe operation of the power system. The dry-type air-core reactors currently used in power systems are usually still closed products, which are characterized by the use of multi-layer insulated wires closely wound, so the volume is small; the disadvantage is that there is a large difference between the temperature coefficient of the metal wire and the insulating material. The difference is that when the product is running online, it is prone to surface cracks, dirt absorption, and even dendritic discharge at the end of the ring body. In addition, it is noisy and the product is poor in interchangeability. (3) Contents of the invention [0003] The object of the present invention ...
