Frame type dry hollow controllable reactor

Abstract

The invention discloses a frame type dry hollow controllable reactor which comprises an inductive coil, a sensor, an electromagnetic device and a controllable adjusting device, wherein the inductive coil and the sensor adopt a structure that insulated lead wires are embedded and wound in tooth grooves of an insulated rack set uniformly distributed in the circumferential direction and on one side of the insulated rack set, supporting rings are embedded into the inner side, and reinforcing rings are wound on the outer layer; an adjusting coil is in circuit connection with the inductive coil through an adjusting terminal, a connecting piece and a connecting kit; both the adjusting coil and the connecting kit are fixed to a lower hanging rack. According to the reactor, the inductive coil and the adjusting coil are randomly positioned and mounted by the connecting kit, the adjusting operation is convenient, the inductance value is guaranteed to be within a controllable parameter, and the user requirements are met.

Description

technical field [0001] The invention belongs to the field of reactors, in particular to a frame-type dry-type hollow controllable reactor. Background technique [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. Contents of the invention [0003] The object of the present invention is to solve t...

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.
