Abstract

The invention provides a trap-typed capacitor fixing device, consisting of an electrolytic capacitor, an upper capacitor fixing plate, a lower capacitor fixing plate and a fixing support frame. The fixing support frame is arranged at the left and right ends of the upper capacitor fixing plate and the lower capacitor fixing plate. The fixing support frame takes the shape of 'I' and is fixed by bolts. Six to twelve grooves are processed on the internal surface of the upper capacitor fixing plate and are distributed in two rows at intervals. Two layers of counterbores are processed on the lower capacitor fixing plate at the positions corresponding to the grooves of the upper capacitor fixing plate. The terminal of the electrolytic capacitor faces the counterbores of the lower capacitor fixing plate while the other end stretches into the grooves of the upper capacitor fixing plate. The device fastens the capacitor module and facilitates modularized mounting and demounting. The device has excellent insulativity. The device adopts an integral design, wherein, fixing, mounting and wiring of the capacitor are integrated. The device is applicable for the fields of rail vehicle, light rail,subway, Maglev train, industrial converter, etc.

Description

technical field [0001] The invention relates to a fixing device for capacitors. Background technique [0002] At present, the converter power supply products developed by using power electronic technology have been widely used in various fields such as electric power, military industry, industry, commerce, agriculture, etc., and only one inverter is used in all walks of life all over the world. With the continuous improvement and development of power electronics application technology, the advantages of converters in energy saving, environmental protection and other aspects are increasingly reflected, and have been widely recognized by users. [0003] Due to its vast market space and social needs, converters are also rapidly developing towards small size and large capacity. The core part of the cabinet structure is the power unit, and the fixing, installation and wiring of DC voltage support capacitors are One of the most important issues of the electrical structure of the...
