Embodiment Construction

[0019] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in combination with specific embodiments and with reference to the accompanying drawings. It should be understood that these descriptions are exemplary only, and are not intended to limit the scope of the present invention. Also, in the following description, descriptions of well-known structures and techniques are omitted to avoid unnecessarily obscuring the concept of the present invention.

[0020] In the prior art, the winding of the core reactor coil mainly adopts placing solid resin airway support strips between the wire layers, and at the same time, two layers of 0.23DMD insulating material are padded inside and outside the resin support strips. The disadvantage of adopting the above technical solution is that there may be the problem of insufficient DMD resin impregnation on both sides of the airway; at ...

Abstract

The invention relates to an embedded glass fiber air passage of a reactor coil and the reactor coil, the embedded glass fiber air passage mainly comprises glass fibers, a marble mixture and a curing agent, the strength of the formed glass fiber air passage is greatly improved after the glass fibers are impregnated with the marble and the curing agent mixture and subjected to high-temperature curing, and the strength of the formed glass fiber air passage is greatly improved. And a good supporting effect between layers of the coil can be achieved. According to the technical scheme, the embedded glass fiber air channel is adopted, the link that the air channel is knocked and taken out after the coil is poured is omitted, the air channel cracking problem is avoided, and meanwhile good heat dissipation performance and high production efficiency are achieved.

Description

technical field [0001] The invention relates to the technical field of electric equipment components, in particular to an embedded glass fiber air channel of a reactor coil and the reactor coil. Background technique [0002] As an important power equipment component in the power system, the core series reactor plays the role of withstanding the closing overvoltage of the power system. It can be used in conjunction with capacitors to eliminate high-order harmonics in the power system. At the same time, it plays a reactive role in the power system. The role of compensation. The coil temperature rise during the operation of the iron core series reactor product and the withstand voltage requirement of the product during the on-site handover test are the main assessment characteristics of the reactor performance. Based on the above-mentioned product assessment requirements, in the production process of core series reactors, the control of withstand voltage and coil temperature r...
