Abstract

The invention discloses a converter power device. The converter power device comprises a retaining body, a power component and a capacitor component, wherein the retaining body is internally providedwith two mounting spaces separated from each other, and the two mounting spaces respectively correspond to mounting of a part belonging to the power component and a part belonging to the capacitor component. According to the converter power device, the two separated mounting spaces are arranged, parts belonging to different functional components are respectively mounted in the two spaces, and whenthe parts of the functional components belong to the spaces are repaired and replaced, the parts of the other functional component in the spaces are not affected or damaged.

Description

technical field [0001] The invention relates to the technical field of wind power, in particular to a power device of a wind power converter. Background technique [0002] With the continuous improvement of the power level of the wind power industry, the power of the converter has changed from the original tens of kilowatts to the current several megawatts or even tens of megawatts. The diameter of the tower and the tower where the converter is installed has not increased significantly due to the increase in power level. This requires continuously increasing the power density of the converter, that is, increasing the output power per unit space of the converter. [0003] In order to increase the power density of the converter, in the prior art, all components of the power unit (or device) of the converter (these all components include power components and capacitor components divided by function) are densely installed in one space , this will inevitably lead to the followi...
