Epoxy mould dry type vibration reduction denoise iron core shunt reactor

Abstract

An epoxy resin cast dry-type vibration-damping and noise-reducing iron core paralleling reactor comprises a iron core, a wire circle and a vibration-damping and a noise-reducing device, wherein the iron core is composed of upper and lower yokes and three phase core limbs. The upper and lower yokes are respectively clamped by clips, the centre of the center circles of the upper and lower yokes is utilized as benchmark, the iron core is arranged on the lower yoke along the direction of the 120 DEG included angle of the three phase core limbs with Chinese character 'pin' type, the wire circle is coated on the three phase core limbs and the iron is connected with the vibration-damping and noise-reducing device. The invention changes the traditional '-' structure into the Chinese character 'pin' type, if casting dry-type product for the epoxy resin, simultaneously the structure of one wire circle of each phase is divided into a plurality of wire circles with upper independent, which increases the safety and reliability of operation, the invention adds pressing frames between the iron core and the elastic rubber cushion, the structure of which can better reduce vibration, decrease noise and has relatively good reliability.

Description

technical field [0001] The invention relates to a reactor in the field of electric technology, in particular to an epoxy cast dry-type vibration-reducing and noise-reducing iron-core shunt reactor. Background technique [0002] With the rapid development of the power industry, overhead lines and cables are getting longer and longer. When the power grid is under no-load and light-load conditions, the leading reactive power increases, which brings disadvantages such as increased power frequency voltage and increased losses. The shunt reactor is used to compensate the leading reactive power of the line, limit the increase of the power frequency voltage of the system and the operating overvoltage, reduce the line loss, etc., and is an important equipment to improve the quality of power grid operation. At present, the widely used epoxy cast dry-type iron core shunt reactor usually adopts a "one" shape structure, which has problems such as large vibration, high noise, and large co...

AI Technical Summary

Problems solved by technology

"However, the shunt reactor still cannot solve the above problems, and there are still problems such as large vibration, high noise, and large consumption of iron choke materials.
