Abstract

The invention belongs to the technical field of manufacturing transformer products, and in particular relates to an internal support structure of an air-core coil. It includes laminated wood components, pull rods, upper yokes, lower yokes and multiple sets of porcelain spacer components, wherein multiple sets of porcelain spacer components are limited on the laminated wood components along the circumferential direction, and the upper and lower ends of the laminated wood components are respectively provided with The upper yoke and the lower yoke are connected by tie rods. The invention reduces the vibration amplitude of the body and the fuel tank by 60%, and the overall noise value of the air-core reactor is significantly reduced; at the same time, the internal support force of the coil is increased to integrate the extrusion force from both ends to the middle, and the deformation of the coil due to force is avoided. , affecting coil performance.

Description

technical field [0001] The invention belongs to the technical field of manufacturing transformer products, and in particular relates to an internal support structure of an air-core coil, which is applied to high-current air-core reactor products. Background technique [0002] DC icing mainly applies DC voltage to the transmission line and short-circuits the end of the transmission line to make the wire heat up and melt the ice of the transmission line, so as to avoid the line being broken due to icing. The DC deicing device is an important means to deal with the deicing of severely iced lines, and it is characterized by large rated current value and strong linearity of fixed reactance value. According to the above characteristics, the ice-melting reactor adopts a hollow structure, in order to improve the requirements of high current and high strength. Conventional air-core reactor windings have no iron core support inside, and have the characteristics of constant reactance ...
