A high power converter

Abstract

The invention discloses a high-power converter, the structure of which comprises a motor, a heat dissipation net, a conversion box, a main engine, and a cabinet door. A conversion box is connected, one side of the conversion box is connected with a heat dissipation net, the host includes a cabinet body, a windshield, a rotating shaft, a base pad, a booster ball, and an air duct, and a windshield is connected between the cabinet body and the conversion box through a rotating shaft, and It is connected with an air duct inside, and one side of the air duct is connected with a base pad, and a booster ball is arranged on the base pad, and a side pressure device and a roof partition structure are arranged on the booster ball. Cooperating, when the windshield will keep the corresponding gear floating up and down along the wind, it will first touch the middle of the stacking tube, so that the stacking tube is squeezed and slides between the side pressure devices, and the side pressure device is pushed to lean against the roof structure , can be V-shaped socketed on the windshield to maintain a better stability of the card stop.

Description

technical field [0001] The invention relates to the field of high-power semiconductor devices, in particular, it is a high-power converter. Background technique [0002] The ITERPF converter power supply is the special power system with the largest power and the most complex operation mode in the world today. The rated current of a single converter is ±55kA, the rated voltage is ±1.05kV, and it can realize four-quadrant operation. There are 14 sets of four-quadrant converters in total. The power supply of the inverter supplies power to six PF superconducting coils, among which PF2-PF5, the power supplies of these four superconducting coils are composed of three four-quadrant high-power converters in series, and the starting pair of three high-power converters running in series The safe and reliable operation of the power supply is very important, and the existing high-power converters will have the following disadvantages: [0003] Generally, the heat dissipation air duct o...

Problems solved by technology

[0003] Generally, the heat dissipation air duct of the power unit forms an air duct in the inner cavity of the cabinet body, and the air suction port of the heat dissipation box is facing the air duct, which can use the opening of the windshield part to attract convective air and improve the heat dissipation efficiency of the heat sink. After the convective wind slides and opens in the same direction and reaches the preset position, the windshield will still float up and down in the corresponding position along the wind, and rigidly collide with the air ducts on both sides, so that the corners of the windshield are damaged to varying degrees. Affecting the subsequent deployment cannot maintain a parallel state, resulting in poor convection cooling effect and reducing the ability of the overall equipment to operate stably
