Water-cooling electric reactor

Abstract

The invention discloses a water-cooling electric reactor which comprises three groups of windings, an iron core, cooling pipelines and water distributors, wherein the windings are wound on the iron core; the cooling pipelines are positioned in the windings; the pipe joints of the cooling pipelines are positioned below the windings; the water distributors are positioned at the two ends of the electric reactor; two joints are arranged on the water distributors; the joints are connected with the cooling pipelines respectively; and coil ending rows and coil starting rows are also arranged on the windings. According to the water-cooling electric reactor, the pipe joints of the cooling pipelines are arranged below the windings, and the water distributors are arranged on the two sides of the electric reactor, so that the pipe joints can be prevented from leaking water; and the stable and safe running of the water-cooling electric reactor is guaranteed, and the water-cooling electric reactor is strong in practicality.

Description

technical field [0001] The invention relates to a waterway pipeline, in particular to a waterway pipeline used for a water-cooled reactor. Background technique [0002] With the rapid development of power technology and the continuous improvement of current power equipment's requirements for high-performance and high-reliability electrical systems, due to the continuous increase in power system capacity and switching frequency, the loss of power distribution devices such as reactors will inevitably increase. , and the inverter of the reactor is developing toward large-capacity control, reliability, and miniaturization. Therefore, how to control the temperature of the reactor without significantly increasing the volume of the reactor has become an important step. The general technical solution is to carry out water cooling. The principle is to use the industrial water cooling system that comes with the frequency converter, and add a water cooling system to the reactor, so tha...
