Problems solved by technology

When the voltage level of the product is further increased, the creepage voltage borne by the insulating parts will increase, which will bring potential safety hazards to the product
[0003] In this way, when the voltage and capacity acting on the iron core reactor reach a certain level, due to the limitation of transportation and insulating materials, a single iron core and coil can no longer meet the transportation and insulation requirements of high voltage and large capacity products.

Embodiment 1

[0025] Such as figure 1 , 2 , 7 shows that the reactor in this embodiment adopts a double-body reactor, which includes a reactor main body 3 and an oil conservator 4 . The reactor main body 3 includes two separate reactor bodies, and the two reactor bodies form a double-body structure, and the two bodies are connected together through their internal coils. Both reactor bodies are placed in the reactor oil tank 6, and the oil tank 6 communicates with the oil conservator 4.

[0026] Such as Figure 7 As shown, in this embodiment, four sets of radiators 5 are connected to the fuel tank 6 , and the radiators 5 are symmetrically distributed on both sides of the fuel tank 6 .

[0027] Such as Figure 3-6 As shown, in the double-body reactor of this embodiment, each body includes a sun-shaped iron core 7 and a coil 8, and in the middle of each sun-shaped iron core are a plurality of iron core cakes 9 with central holes and a plurality of air gaps The core column 10 formed by ove...

Abstract

The invention discloses a heat radiation structure of a reactor, comprising a radiator connected on an oil tank of the reactor, wherein a reactor main body comprises two or more than two independent bodies, and the reactor bodies are connected together by coils in the reactor bodies. The invention can meet the requirement of a reactor with high voltage and large capacity, is favorable to the heatradiation of a winding in every reactor body and has the advantages of simple assembly and reliable operation.

Description

technical field [0001] The invention belongs to the technical field of reactors, and relates to a heat dissipation structure of a reactor. Background technique [0002] Existing single-phase core reactors are all made of a single Japanese-shaped core and a single coil. This structure is suitable for products with a certain voltage and a certain capacity, but when the voltage level and capacity reach a certain level (such as the voltage level is 800KV, capacity of 100000kvar), with the increase in size of the product, the width and height of the product will further increase, which brings difficulties to the transportation of the reactor. In addition, since the creepage distance of the insulation of the product itself is limited, it is not possible to allow an unlimited increase in voltage under a certain insulation distance. When the voltage level of the product is further increased, the creepage voltage borne by the insulating parts will increase, which will bring potentia...
