Description

A Distributed Iron Core Reactor Used in Reactive Power Compensation Device

technical field

The utility model relates to a reactor, in particular to a distributed iron core reactor used for a reactive power compensation device.

Background technique

A reactor is also called an inductor. When a conductor is energized, it will generate a magnetic field in a certain space it occupies, so all electric conductors that can carry current have inductance in the general sense. However, the inductance of long and straight conductors is generally small, and the magnetic field generated is not strong, so the actual reactor is in the form of a solenoid wound with wires, which is called an air-core reactor; in order to make the solenoid have greater inductance, it is Inserting an iron core into the solenoid is called an iron core reactor. In outdoor reactive power compensation devices, due to the influence of environmental factors, dry-type air-core reactors are usually used, but dry-type air-core reactors also have the following shortcomings: large volume, large footprint, and wide range of magnetic flux leakage , high active loss.

Utility model content

The purpose of this utility model is to solve the problems mentioned in the above background technology part by a distributed iron core reactor used for reactive power compensation device.

For this purpose, the utility model adopts the following technical solutions:

A distributed iron-core reactor for reactive power compensation devices, which includes a reactor body; the reactor body includes coils, several strip iron cores of the same specification and brackets, and the strip iron cores are evenly arranged on the line Within the inner diameter of the ring; the strip iron core is fixed on the bracket after epoxy casting as a whole.

In particular, the number of strip iron cores to be added depends on the capacity of the distributed iron core reactors used for reactive power compensation devices.

The distributed iron core reactor used for reactive power compensation device proposed by the utility model is equipped with a distributed strip iron core on the basis of the traditional air core reactor, so that the reactor has the advantages of iron core reactor and air core reactor at the same time , not only effectively reduces the volume of the reactor, correspondingly reduces the occupied area, but also reduces the flux leakage and low active power loss.

Unless otherwise defined, all technical and scientific terms used herein are consistent with the present utility model. Those skilled in the art generally understand the same meaning. The terms used herein are only for the purpose of describing specific embodiments, and are not intended to limit the present utility model.

Please refer to FIG. 1 , which is a structural diagram of a distributed iron core reactor used in a reactive power compensation device provided by an embodiment of the present invention.

The distributed iron-core reactor used in the reactive power compensation device in this embodiment includes a reactor body 101 ; The strip iron core 103 is evenly arranged within the inner diameter of the coil 102; the strip iron core 103 is fixed on the bracket 104 after epoxy casting, and outside the strip iron core 103 after epoxy casting An epoxy resin insulating layer 105 is formed. Wherein, the installed quantity of the strip iron core 103 is determined according to the capacity of the distributed iron core reactor used for the reactive power compensation device. The coil 102 has the same structure as the coil 102 of the outdoor dry-type air-core reactor.

The technical scheme of the utility model adds a distributed strip iron core on the basis of the traditional air-core reactor, so that the reactor has the advantages of the iron-core reactor and the air-core reactor at the same time, not only effectively reducing the volume of the reactor, but also correspondingly The footprint is greatly reduced, and the magnetic flux leakage is reduced, and the active loss is low. It is proved by experiments that the diameter of the reactor coil of the distributed iron core reactor proposed by the utility model can be reduced by 20%-40% compared with the diameter of the air-core reactor, and the active loss of the reactor can be reduced by 15%-25%.
