Detailed Description

In order to make the technical means, the creation characteristics, the achievement purposes and the effects of the utility model easy to understand, the utility model is further described with the specific embodiments.

As shown in fig. 1 to 6, an insulation structure of a reactor, including a reactance basic unit 1, yokes 2 and connecting plates 3, the reactance basic unit 1 is provided with a plurality of units, the reactance basic unit 1 includes a support 11, a coil winding 12, an iron core 13 and an insulation shield 14, the iron core 13 is arranged in the support 11, the coil winding 12 is arranged outside the support 11, a protruding structure 111 is arranged on the upper and lower surfaces of the support 11, the insulation shield 14 is sleeved outside the protruding structure 111, clamping plates 15 are arranged in the support 11 and on two sides of the iron core 13, the yokes 2 are arranged in two parts, respectively arranged on the upper and lower ends of the support 11, the yokes 2 are also arranged between the two clamping plates 15 of the same reactance basic unit 1, an upper air duct box 16 and a lower air duct box 17 are further arranged between the yokes 2 and the support 11, and the clamping plates 15, the yokes 2 and the connecting plates 3 are fixedly connected together through bolts.

In this embodiment, a pre-groove 113 is further provided on the protruding structure 111 of the bracket 11, and the pre-groove 113 is used for the terminal of the coil winding 12 to pass through.

In this embodiment, in order to avoid the influence of the insulating shield 14 on the normal heat dissipation of the coil winding 12, the insulating shield 14 is provided with a plurality of vertical through grooves 141 and horizontal through grooves 142, and a gap is left between the insulating shield 14 and the coil winding 12, so that a good wind leakage effect is ensured, and the heat dissipation efficiency is improved.

In this embodiment, since the heat inside the coil winding 12 is not easy to dissipate, a plurality of grooves 112 penetrating up and down are formed in the outer wall of the bracket 11, and the grooves 112 are communicated with the upper air duct box 16 and the lower air duct box 17 to realize airflow conduction, and a plurality of air outlets 161 are formed in the upper air duct box 16 for heat dissipation. An air inlet hole 171 is formed in the lower air duct box 17, and the air inlet hole 171 is located on the back face of the reactor and is convenient to connect with an air pipe. The air inlet and outlet structure is used for being communicated with a heat dissipation air source, so that air flow from top to bottom is formed in the groove 112, the heat dissipation can be better realized by matching the characteristic that hot air has a rising trend, the difference between the upper air channel box 16 and the lower air channel box 17 is only on the air inlet hole 171 and the air outlet hole 161, and other internal structures are the same.

The working process and the principle thereof are as follows:

when the reactor is used, a heat dissipation air source is communicated with the air inlet 171 of the lower air duct box 17 through the air pipe, heat dissipation air flow enters the lower air duct box 17 through the air inlet 171, because the upper air duct box 16 and the lower air duct box 17 are open, the groove 112 is positioned in the upper air duct box 16 and the lower air duct box 17 and is communicated with the bracket 11, the air flow can enter the groove 112, and the groove 112 is directly contacted with the inner side of the coil winding 12, so that heat generated on the inner side of the coil winding 12 and heat generated by the iron core 13 absorbed by the bracket 11 can be taken away by the air flow when the air flow passes through the groove 112 and then discharged from the air outlet 161 on the upper air duct box 16, and therefore heat dissipation on the inner side of the coil winding 12 is improved.

A gap is left between the insulating shield 14 and the coil winding 12 at the outer side of the coil winding 12, so that the coil winding 12 can be protected from being scratched and collided with the outside, electric leakage of the damaged coil winding 12 is avoided, and the heat dissipation requirement at the outer side of the coil winding 12 can be ensured by arranging the vertical through groove 141 and the horizontal through groove 142 on the insulating shield 14.
