Therefore, a plurality of three-phase alternating current reactors with different sizes are integrated into a combined three-phase alternating current reactor. Compared with a plurality of mutually independent three-phase alternating current reactors, the combined three-phase alternating current reactor provided by the invention has the advantages of less material consumption, small volume and low production cost.
Description
Technical Field
The utility model relates to a reactor, concretely relates to three-phase alternating current reactor.
Background
According to the prior art, a three-phase ac reactor, regardless of size, has an independent core and three coils wound around the core.
SUMMERY OF THE UTILITY MODEL
The utility model solves the technical problem that: a plurality of three-phase alternating current reactors with different sizes are integrated.
In order to solve the technical problem, the utility model provides a following technical scheme: the combined three-phase alternating current reactor comprises a plurality of three-phase alternating current reactors with different sizes, wherein the three-phase alternating current reactors with different sizes are vertically stacked, two vertically adjacent three-phase alternating current reactors share one iron yoke, and the shared iron yoke is the iron yoke of the larger three-phase alternating current reactor in the two vertically adjacent three-phase alternating current reactors.
The above technical scheme has two main points: firstly, the three-phase ac reactors stacked up and down must have different sizes, because the shared yoke can bear smaller reactance magnetic flux when bearing larger reactance magnetic flux, if the shared yoke needs to bear larger reactance magnetic flux from the upper part and also bears larger reactance magnetic flux from the lower part, the shared yoke will not bear heavy load; second, since two three-phase ac reactors adjacent to each other vertically share a yoke, the yoke of the smaller three-phase ac reactor of the two three-phase ac reactors adjacent to each other vertically is omitted, and thus, a plurality of three-phase ac reactors having different sizes are integrated into a combined three-phase ac reactor.
Compare in a plurality of three-phase alternating current reactors independent of each other, combination formula three-phase alternating current reactor, the consumptive material is few, small, low in production cost.

Detailed Description
The combined three-phase alternating current reactor comprises a plurality of three-phase alternating current reactors with different sizes, wherein the three-phase alternating current reactors with different sizes are vertically stacked, two vertically adjacent three-phase alternating current reactors share one iron yoke, and the shared iron yoke is the iron yoke of the larger three-phase alternating current reactor in the two vertically adjacent three-phase alternating current reactors.
Alternatively, a plurality of three-phase alternating current reactors with different sizes are superposed according to the rule that the small three-phase alternating current reactor is arranged above the large three-phase alternating current reactor and below the large three-phase alternating current reactor.
As a further alternative, as shown in fig. 1, the three-phase ac reactors of different sizes include a small three-phase ac reactor 10 and a large three-phase ac reactor 20.
In a plurality of three-phase alternating current reactors with different sizes, any yoke connecting plate is installed on any yoke, and any yoke connecting plate is connected with the yoke connecting plates which are adjacent up and down through a screw rod.
Taking the combined three-phase ac reactor including a small three-phase ac reactor 10 and a large three-phase ac reactor 20 as an example, with reference to fig. 4 and 5, the upper yoke of the small ac reactor 10 is a small iron yoke 11, and the lower yoke of the small ac reactor, i.e., the upper yoke 23 of the large three-phase ac reactor, shares an iron yoke. The small-sized iron yoke 11 is provided with a first connecting seat 12, the iron yoke shared by the small-sized three-phase alternating current reactor 10 and the large-sized three-phase alternating current reactor 20 is provided with a second connecting seat 21, and the lower iron yoke 24 of the large-sized three-phase alternating current reactor is provided with a third connecting seat 22. The first screw 31 connects the first connecting seat 12 and the second connecting seat 21, and the second screw 32 connects the second connecting seat 21 and the third connecting seat 22. Thus, the whole combined three-phase alternating current reactor becomes a stable whole.
In both the small three-phase ac reactor 10 and the large three-phase ac reactor 20, the core includes a core portion for winding the coil and yokes at two ends of the core portion, and a gas piece (not shown in the drawings) is disposed at a joint of the core portion and the yokes, i.e., a plastic piece, the gas piece is sandwiched between the core portion and the yokes, and the gas piece is bonded to the core portion and the yokes. As the current in the coil increases, the magnetic flux in the core saturates quickly, and in order to delay the saturation, the air sheet is clamped in the core, so that the linearity of the inductance is improved.
The above description is only for the preferred embodiment of the present invention, and for those skilled in the art, there are variations on the detailed description and the application scope according to the idea of the present invention, and the content of the description should not be construed as a limitation to the present invention.
