Coiling fixture, with air channel supporting bar positioning function, of iron-core-type electric reactor

Abstract

The invention discloses a coiling fixture, with an air channel supporting bar positioning function, of an iron-core-type electric reactor. The iron-core-type electric reactor comprises an iron core, wires coiled on the iron core and copper bars fixedly arranged on the end portions of the wires. The coiling fixture comprises a transmission rod, a front clamping plate and a rear clamping plate, wherein the front clamping plate comprises a front clamping plate bottom plate, a front loop edge and a positioning plate, wherein the front clamping plate bottom plate is coaxially and perpendicularly arranged with the transmission rod, the front loop edge is arranged in the center of the rear side of the front clamping plate bottom plate, the iron core can be clamped and embedded in the front loop edge, and the positioning plate and the front clamping plate bottom plate are fixedly connected and are parallelly arranged. The coiling fixture is simple in structure. Because the iron core is positioned in a clamping mode, U-shaped positioning grooves are arranged on the peripheries of bottom plates of the front clamping plate and a rear clamping plate, and air channel supporting bars are clamped and embedded in the U-shaped positioning grooves, the air channel supporting bars only need simply clamping in the coiling fixture in the coiling process, and accordingly the air channel supporting bars can be positioned and will not deviate, and product quality is improved. Meanwhile, the front clamping plate and the rear clamping plate can be simply drawn out in an axial direction when the coiling fixture is disassembled. The coiling fixture is convenient to operate.

Description

technical field [0001] The invention relates to the technical field of reactor processing, in particular to a winding fixture for an iron core reactor with the function of positioning airway support bars. Background technique [0002] The main components of the electrical circuit are resistance, capacitance and inductance. The inductance has the function of inhibiting the change of current and can make the phase shift of the alternating current. Usually, the winding static induction device with inductance is called a reactor. [0003] Common reactors used in power systems are series reactors and shunt reactors. The series reactor is mainly used to limit the short-circuit current, and it is also connected in series or parallel with the capacitor in the filter to limit the higher harmonics in the grid, and the operating voltage can also be adjusted by adjusting the number of shunt reactors. [0004] Reactors can be divided into hollow type, iron core type, dry type, oil-immer...

AI Technical Summary

Problems solved by technology

[0004] Reactors can be divided into hollow type, iron core type, dry type, oil-immersed type, etc. according to the structure and cooling medium. At the same time, according to the different winding materials, they are also divided into copper foil wound reactors and copper tape wound reactors. In specific winding During preparation, it is necessary to wind a predetermined number of turns of copper foil or copper strip layer by layer on the hollow support or iron core. After the end of the foil or copper strip is fixed, it is wound with a winding machine, but now there is a lack of a special fixture that can quickly position the iron core and stably realize the positioning of the copper bar and the winding of the copper foil or copper strip, resulting in low winding efficiency. Product quality cannot be well controlled

Especially in some reactors, it is necessary to design the air passage to improve its heat dissipation performance, which requires the installation of air passage support bars between the windings, but the existing winding fixtures cannot provide positioning functions, resulting in inconvenient operation
