Embodiment 1

[0025] Figure 1 to Figure 4 An embodiment of the present invention is shown. The air-core reactor with coil protection function in this embodiment includes a left end plate 1, a right end plate 2, and a plurality of coils sandwiched between the left end plate 1 and the right end plate 2 3. A limiting member 4 is provided between the left end plate 1 and the right end plate 2 . Wherein, there may be one coil 3 in other embodiments.

[0026] In this air-core reactor with coil protection function, a limiting member 4 is set between the left end plate 1 and the right end plate 2, and the length between the left end plate 1 and the right end plate 2 can be restricted by accurately designing the length of the limiting member 4. The structure is simple and reliable. When the reactor is assembled, the coil 3 can be prevented from being damaged by excessive compression, and it can also prevent the deformation of the left end plate 1 and the right end plate 2 to a certain extent.

Embodiment 2

[0031] The air-core reactor with coil protection function of this embodiment is basically the same structure as that of Embodiment 1, the difference is that in this embodiment, the limiting member 4 is a rod and runs through each coil 3, and one end of the limiting member 4 It is against the left end plate 1, and the other end is against the right end plate 2. Both ends of the limiter 4 are provided with threaded holes 45 along the axial direction. Bolts (not shown in the figure), the right side of the right end plate 2 is provided with a fastening bolt that matches the threaded hole 45 at the right end. The limit member 4 of this structure limits the left end plate 1 and the right end plate 2 through the ends of the left and right ends to prevent the two from compressing the coils 3 too much; at the same time, the left end plate 1 and the right end plate are connected by fastening bolts 2 and further clamping each coil 3, the structure of the limiting member 4 is simpler, has...

Embodiment 3

[0034] The structure of the air-core reactor with coil protection function in this embodiment is basically the same as that in Embodiment 1, the difference is that in this embodiment, the limiting member 4 is a rod and runs through the left end plate 1, each coil 3, and the right end plate 2. The diameter of the middle section of the limiting member 4 is greater than the diameter of both ends, and the positions of the diameter changes at both ends of the limiting member 4 are offset against the left end plate 1 and the right end plate 2 respectively. The threaded segments 41 are each associated with a union nut 42 .

[0035] In this embodiment, an insulating layer is provided on the surface of the limiting member 4 .

Abstract

The invention discloses an air-core reactor with a coil protection function. The air-core reactor comprises a left end plate, a right end plate as well as one or multiple coils clamped between the left end plate and the right end plate, and a limit part is arranged between the left end plate and the right end plate in a contact way. The air-core reactor disclosed by the invention has the advantages that structure is simple and reliable and the coils can be prevented from being damaged after being compressed excessively.

Description

technical field [0001] The invention relates to a reactor, in particular to an air-core reactor with a coil protection function. Background technique [0002] In the existing air-core reactor, the coils are arranged side by side during assembly, and insulating pads are set between adjacent coils, and then the coils are clamped by the left and right end plates, and the two end plates are usually connected by screws. It runs through each coil and insulating spacer, and is locked by nuts at both ends. When assembling various types of air-core reactors, due to the lack of objective reference and other reasons, the operators may over-tighten the nuts, resulting in excessive compression and damage to the coils of the air-core reactors, and even deformation of the left and right end plates, affecting Assembly quality. Contents of the invention [0003] The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art, and provide an ai...
