Problems solved by technology

[0002] At present, the cooling of high-voltage equipment uses insulating media. The commonly used media are air, water, and oil. Insulating media tend to generate heat during the circulation process, and are not easy to dissipate heat. At the same time, due to the difference in the heat capacity characteristics of the media, the cooling effect varies greatly.
However, according to the existing technical knowledge, in order to avoid short circuit, the conductive medium cannot be used as the circulating medium in the high-voltage equipment, and the operation reliability of the equipment is directly related to the insulation performance of the cooling medium

Abstract

The invention relates to a system for cooling high-voltage equipment by utilizing a conductive medium. The system comprises a heat radiator, a circulating pump and a conductive medium isolation device, wherein the high-voltage equipment to be cooled is connected between the circulation pump and the conductive medium isolation device; the conductive medium isolation device comprises at least two transition hoppers and a recovery hopper which are arranged in sequence from top to bottom, and one transition hopper is capable of conveying the conductive medium to the lower adjacent hopper; an insulating guide pipe connected with an outlet of the high-voltage equipment extends into the uppermost transition hopper, and the bottom part of the recovery hopper is connected to the heat radiator via the insulating guide pipe; and the transition hoppers are under interlocked control, so that at least one transition hopper cannot convey the conductive medium to the lower adjacent hopper in the same period of time. The system provided by the invention breaks the existing concept, uses the conductive medium as a cooling medium of the high-voltage equipment, reduces resistance of the medium, reduces heat generation, is conductive to heat radiation, and can neglect insulation requirements of an insulating medium when the system is applied to a traditional cooling system.
