Problems solved by technology

Its disadvantages are as follows: First, when the large reactor is working, the coil heating will generate a lot of heat, which directly affects the working efficiency of the reactor. In order to achieve the purpose of cooling, people try various methods, such as water cooling, air cooling etc. First, the power capacity is limited; second, the manufacturing cost is high, labor-intensive and time-consuming

Abstract

The invention relates to a high-capacity reactor composed of multiple circles of mutually insulated copper sheets and a manufacture method of the high-capacity reactor, wherein the high-capacity reactor adopts the mutually insulated copper sheet coil to replace a coil in a coiling bag, is simple in structure, convenient to use and good in air cooling effect and can effectively increase inductance at the same time. The high-capacity reactor comprises a reactor, and the coil in the coiling bag of the reactor is formed by a plurality of layers of mutually insulated copper sheets, moreover, a plurality of isolation insulation bars are arranged among the mutually insulated copper sheets. The high-capacity reactor has the advantages that, 1, the technical problem that the reactor is reduced in quality and frequent in failures caused by the overheat of the coil of the reactor, which is not solved for a long time is solved; and 2, the manufacture cost is greatly reduced, the labor and the time are saved, and the efficiency is high.

Description

technical field [0001] The invention relates to a multi-layer mutually insulated copper coil which adopts mutually insulated copper coils to replace traditional wire-wrapped coils, has simple structure, is convenient to manufacture, has good air-cooling and cooling effects, and can effectively increase inductance and capacity at the same time. The large-capacity reactor belongs to the field of reactor manufacturing. Background technique [0002] In terms of structural design, the existing large-capacity reactors rely on the inductive reactance of the coil to block the electrical appliances that change the current. According to the purpose, it can be divided into 7 types: (1) Current-limiting reactor: connected in series in the power circuit to limit the value of the short-circuit current. ⑵Shunt reactor: Generally connected between the end of the ultra-high voltage transmission line and the ground, it plays the role of reactive power compensation. (3) Communication reactor...
