New filter reactor

technical field

The utility model relates to a reactor, in particular to a novel filter reactor.

Background technique

Reactors are electrical appliances that rely on the inductive reactance of the coil to block current changes, and are widely used in the fields of wind power generation and photovoltaic power generation. Traditional reactors require a large volume, which not only increases the size of the power cabinet, wastes the limited space of the converter cabinet, increases the overall cost, but also increases power consumption and noise.

Utility model content

Aiming at the deficiencies of the prior art, the utility model proposes a novel filter reactor, which can solve the problems of large volume, high cost and high power consumption of the existing reactor.

In order to achieve the above object, the technical scheme adopted in the utility model is as follows:

The new filter reactor includes an upper iron yoke, a lower iron yoke parallel to the upper iron yoke, and three iron-silicon magnetic powder cores connected between the upper iron yoke and the lower iron yoke. The iron-silicon magnetic powder core is composed of multiple iron-silicon magnetic The block units are stacked by glue bonding, and the iron-silicon magnetic powder core is fired with coil windings.

Preferably, an air gap plate is arranged between two adjacent iron-silicon magnetic block units, and fiberglass felt plates are respectively arranged on the bonding surfaces of the iron-silicon magnetic powder core and the upper iron yoke and the lower iron yoke.

Preferably, both the upper iron yoke and the lower iron yoke are formed by stacking a plurality of iron core laminations with the same shape and size.

Preferably, it also includes an upper iron yoke clamping device and a lower iron yoke clamping device; the upper iron yoke clamping device includes a pair of upper iron yoke splints respectively clamped on two opposite upper iron yoke sides, There is also an upper connecting plate for preventing the upper iron yoke from moving upward in the vertical direction between the two upper iron yoke splints; the lower iron yoke clamping device includes a pair of The upper lower iron yoke splint, and the lower connecting plate for preventing the lower iron yoke from moving downward in the vertical direction is also arranged between the two lower iron yoke splints.

Preferably, the thickness of the air gap plate is 1 mm, and the thickness of the fiberglass mat plate is 1-2 mm.

Compared with the prior art, the utility model adopts iron-silicon magnetic powder core as the coil center column of the reactor, which is composed of a plurality of iron-silicon magnetic block units bonded and stacked by high-temperature glue, so that the whole reactor has a compact structure and a small volume. Smaller, thereby effectively reducing production costs and power consumption.

Detailed ways

In the following, the utility model will be further described in conjunction with the accompanying drawings and specific embodiments, so as to understand more clearly the technical idea claimed by the utility model.

As shown in Figures 1 to 2, the utility model includes an upper iron yoke 21, a lower iron yoke 22, and three iron-silicon magnetic powder cores 23 connected between the upper iron yoke 21 and the lower iron yoke 22, wherein the upper iron yoke 21 and the lower iron yoke The yokes 22 are arranged in parallel, and the upper iron yoke 21 , the lower iron yoke 22 and the iron-silicon magnetic powder core 23 together form a closed magnetic circuit of the reactor. Coil windings are fired on the iron silicon magnetic powder core 23 .

Based on the above-mentioned novel filter reactor, the iron-silicon magnetic powder core 23 is formed by stacking a plurality of iron-silicon magnetic block units 231 through high-temperature glue bonding. There is an air gap plate 232, and further, the thickness of the air gap plate 232 is 1 mm. Using the iron-silicon magnetic powder core 23 in the utility model as the coil center column of the reactor, its loss is lower than that of the traditional iron powder core; and the audio noise in the filter reactor can be effectively eliminated by virtue of its low magnetostriction performance.

The two opposite surfaces of the iron-silicon magnetic powder core 23 are combined with the upper iron yoke 21 and the lower iron yoke 22 respectively, and a fiberglass felt plate 24 is also arranged on the joint surface, specifically, the thickness of the fiberglass felt plate 24 is 1 -2mm.

Specifically, both the upper iron yoke 21 and the lower iron yoke 22 are formed by stacking a plurality of iron core laminations with the same shape and size.

As shown in Figure 3, it is another structural diagram of the utility model. On the basis of the above-mentioned new filter reactor, it also includes an upper iron yoke clamping device and a lower iron yoke clamping device, and through the upper iron yoke clamping device And the clamping device of the lower iron yoke makes the entire closed magnetic circuit structure an integral fastening structure. Wherein the upper iron yoke clamping device comprises a pair of upper iron yoke splints 11 respectively clamped on the two opposite upper iron yoke sides, and between the two upper iron yoke splints 11 is also provided for preventing the upper iron yoke 21 from vertically The upper connecting plate 111 that moves upward in the direction. The lower iron yoke clamping device includes a pair of lower iron yoke splints 12 respectively clamped on the two opposite lower iron yoke sides, and there is also a set between the two lower iron yoke splints 12 for preventing the lower iron yoke 22 from moving in the vertical direction. The lower connecting plate 121 that moves up and down. The upper connecting plate 111 and the lower connecting plate 121 can be fixed by screws or by other common fixing methods.

For those skilled in the art, various other corresponding changes and modifications can be made according to the technical solutions and ideas described above, and all these changes and modifications should fall within the protection scope of the claims of the present invention .
