Embodiment Construction

[0016] Hereinafter, the present invention will be further described in detail with reference to the examples and drawings, but the implementation of the present invention is not limited thereto.

[0017] A reactor has a shell, a coil and a magnetic material are contained inside the shell to form a reactance unit 4, and an insulating and thermally conductive filler is provided between the magnetic material wound with the coil and the inner wall of the shell, and the filler is metal oxide powder Mixed with epoxy resin, oxidized metal powder is evenly distributed in epoxy resin. Considering the production cost, in this embodiment, the metal oxide powder is preferably processed alumina powder, and the volume percentage of the metal oxide powder and the epoxy resin is 5:5.

[0018] Such as figure 1 , figure 2 with image 3 As shown, the housing is composed of a plastic side plate 1 and a top plate 2. The side plate 1 includes two right-angled folded plates 11, and the end and end of t...

Abstract

The invention relates to a reactor, which has a shell, and a coil and a magnetic material are accommodated inside the shell, and a coil connection hole is provided on the top surface of the shell, and there is an insulating and Thermally conductive filler, the filler is mixed with oxidized metal powder and epoxy resin, and the oxidized metal powder is evenly distributed in the epoxy resin. The object of the present invention is to provide a reactor. A shell is provided outside the magnetic material with a coil wound inside the reactor, and an insulating and heat-conducting filler is filled between the coil and the magnetic material and the shell, so that the reactor can withstand harmonic shock. When the wave occurs, the heat generated at the moment can be quickly absorbed, avoiding the sharp rise of the local temperature when the magnetic material of the reactor and the coil continuously fight against the harmonic, and at the same time, the heat released by it can be quickly transferred to the outside world, ensuring the stable operation of the reactor , which is beneficial to prolong the service life of the reactor.

Description

Technical field [0001] The invention relates to a reactor, which belongs to the field of electrical appliance manufacturing. Background technique [0002] At present, harmonic reactors are commonly used in various electrical equipment. The coils of the existing reactors are generally exposed in the installation space, and cannot quickly absorb the heat generated by the reactor instantly; when installing or repairing the reactor, the tools used often collide and damage the coil. Or it is corroded by salt spray, which affects performance and use. Summary of the invention [0003] The purpose of the present invention is to overcome the shortcomings of the prior art and provide a reactor. A shell is arranged outside the magnetic material wound with a coil in the reactor, and an insulating and thermally conductive filler is filled between the coil and the magnetic material and the shell. So that the reactor can quickly absorb the instantaneous heat when it fights against harmonics, a...
