The Homogeneouslly-radiating of part extends product service life, improves the reliability of product.
In order to achieve the above-mentioned object of the invention, in the presence of solving the problems, such as prior art, technology that the utility model is taken
Scheme is: a kind of high-power water-cooling current transformer device, including upper and lower two story frame structure being made of bottom plate, side plate and crossbeam,
Slideway bracket and slideway are installed on the side plate of upper story frame structure and upper story frame structure is divided into three parts, each part
It is provided with left and right two symmetrical IGBT power cells, each IGBT power cell, including an IGBT power component, one
Copper busbar, three Absorption Capacitances and a current transformer, symmetrical IGBT power component are conducive to each phase IGBT's
It flows, symmetrical Absorption Capacitance is used to ensure to flow through the consistency of the ripple current inside Absorption Capacitance, extends absorption
The service life of capacitor improves the reliability of product；In addition, being equipped with DC bus, two water segregators and control on bottom plate
Box, DC bus are used for the power supply of IGBT power cell and direct current output, and two water segregators are used for the reasonable distribution of water flow,
Low power devices and control device are installed inside control box, does not interfere with each other, that is, ensure that the unimpeded and air-cooled of cooling air channel
Circulation is good, and keeps the placing space of water-cooling plate reasonable, and heat dissipation is uniform；The installation form of the power cell is pull
Formula, can along slideway direction carry out pull installation, for facilitating installation and maintenance, once break down can be individually replaced and
It is whole with slideway to be fixed as one when IGBT power cell is installed in place by the use repaired without will affect whole current transformer for it
Body.
The utility model beneficial effect is: one side the utility model IGBT power cell is rationally distributed, heating device dissipates
Hot uniform, product structure miniaturization；On the other hand, the installation form of power cell is drawing and pulling type, can be taken out along slideway direction
Installation is drawn, for facilitating installation and maintenance, once breaking down can be individually replaced and be repaired without will affect whole change
Flow the use of device.
