Water-cooled reactor

Abstract

A water-cooled reactor comprises an iron core and a conductive coil arranged on the outer side of the iron core, and is characterized by further comprising a cooling water pipe arranged on the inner side or the outer side of the conductive coil, a water inlet and a water outlet are arranged on the cooling water pipe, and heat conduction medium materials are packaged between the cooling water pipe and the conductive coil. By the water-cooled reactor, the defects of high manufacturing cost and stoppage of an existing hollow copper pipe cooling manner and ununiform heat exchange of an existing plate type cooling manner are overcome. The water-cooled reactor with the advantages in the technical scheme can be applied to electronic equipment, such as transformers and the like.

Description

technical field [0001] The invention relates to a reactor or a transformer, in particular to a water cooling structure adopted therein. 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 parent system of the reactor—the frequency converter is developing towards large-capacity control, high reliability, and miniaturization. Therefore, how to reduce the temperature rise of the reactor while not increasing the volume of the reactor obviously Become the bottleneck of the reactor to adapt to the development of the frequency converter, that is, the heat dissipation problem of the reactor has become the key research direction of the reactor. [0003] The...

Problems solved by technology

But these two kinds of electric water-cooled reactors have their fatal shortcomings. The hollow copper tube water-cooled reactor circulates the water medium in the conductive copper tube, so that the water and electricity are not separated, which has great safety hazards, and its manufacturing process is complicated. , the copper tube needs to be specially customized, which is not conducive to mass production

Although the plate-type water-cooled reactor realizes the separation of water and electricity, it has extremely strict requirements on the quality of the water-cooled plate. If there is a problem with the quality of the water-cooled plate and water leakage occurs, not only the reactor will not work and cannot be repaired, but the entire system will also be affected; The water-cooled plate has strict requirements, which also leads to its high price, and has no advantage in the fierce market competition
