Abstract

The invention relates to a current transformer power unit, in particular to a power unit of power device sharing one water-cooling plate with a capacitor. The power unit is characterized in that: the capacitor and the water-cooling plate have an integrated structure; and the capacitor and the power unit are cooled by the same water-cooling plate. Compared with the prior art, the power unit has the advantages that: 1) the capacitor and the power unit are cooled by the same water-cooling plate, so the problem of thermal expansion of the capacitor and dangers such as explosion caused by heat can be solved; 2) as the capacitor and the water-cooling plate have the integrated structure, the device has a compact structure and a small volume, and is applicable to working environments with low size requirements on the device; and 3) as the capacitor and the water-cooling plate have the integrated structure, the modular design of the device is realized easily, and the device is easy to mount and transport.

Description

The power cell of the shared cooled plate of a kind of power device and capacitor

Technical field

The present invention relates to a kind of current transformer power cell, the power cell of the shared cooled plate cooling of particularly a kind of capacitor and power cell.

Background technology

In the prior art, that electric and electronic devices such as current transformer (as frequency converter) power cell need adopt is self cooling, air-cooled, the mode of heat-pipe radiator, water-cooled is cooled off, but capacitor does not generally adopt special cooling infrastructure usually.Bad as the capacitor heat radiation, can produce thermal expansion, can blast when serious.Particularly be applied in the explosion-proof type current transformer equipment, capacitor is installed in the airtight housing, distributes as the heat that produces and does not go out, and will bring a lot of harm.

Summary of the invention

The power cell that the purpose of this invention is to provide the shared cooled plate of a kind of power device and capacitor, capacitor and cooled plate adopt integrative-structure, the shared cooled plate cooling of electric capacity and power cell, and capacitor adopts water cooling, good heat dissipation effect, compact conformation.

For achieving the above object, the present invention is achieved through the following technical solutions:

The power cell of the shared cooled plate of a kind of power device and capacitor is characterized in that, capacitor and cooled plate adopt integrative-structure, the shared cooled plate cooling of capacitor and power cell.

Compared with prior art, the invention has the beneficial effects as follows:

1) the shared cooled plate cooling of capacitor and power cell has solved the problem of capacitor expanded by heating and the harm such as blast of being heated and bringing;

2) capacitor and cooled plate adopt integrative-structure, make the apparatus structure compactness, and volume is little; Be applicable in the little operational environment of plant bulk requirement.

3) capacitor and cooled plate adopt integrative-structure, and the modularized design of implement device easily is easy to install, transport.

4) capacitor and cooled plate adopt integrative-structure, are specially adapted to anti-exposing to the sun, and the little down-hole occasion of volume requirement.
