Embodiment Construction

[0019] The embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings; it should be noted that the embodiments are illustrative, not restrictive, and cannot limit the protection scope of the present invention.

[0020] This embodiment is described by taking the IGCT power unit string as an example.

[0021] A power device string vertically placed mechanical press-fit unit structure, including a square frame 1, a top plate 5, a bottom plate 7 and a power device string 3, the lower bottom of the square frame is fixed to the bottom plate, and the upper end of the square frame is fixed to the top plate , the bottom plate and the top plate are arranged in parallel, and a plurality of power device strings and other accessories such as insulating pads, bus bars, etc. are installed vertically between the top plate and the bottom plate. The specific structure of the top plate, bottom plate and square frame installation is:

Abstract

The invention relates to a vertically placing mechanical press fitting structure of power device clusters, the vertically placing mechanical press fitting structure of the power device clusters comprises a square frame, a top plate, a bottom plate and power device clusters, the bottom plate is fixedly installed at the bottom in the square frame, the top plate is fixedly installed at the upper end in the square frame, the bottom plate and the top plate are arranged in parallel, and a plurality of power device clusters are vertically installed between the top plate and the bottom plate. According to the power device cluster vertically placing mechanical press fitting structure, the power device clusters are arranged in the vertical direction to ensure that flat plate type power electronic devices maintain an identical posture in assembly, transportation and use as well as maintenance processes, so that corresponding processes are simplified. The flat plate type power electronic devices maintain the horizontal posture in a running process all along, a press fitting force and the device gravity are accordant in direction, and therefore the phenomena that due to the power device clusters are placed horizontally, the devices are stressed unevenly, using faults occur under the long-term mechanical vibration conditions are avoided.

Description

technical field [0001] The invention relates to the fixing of power devices requiring mechanical press-fitting, especially a mechanical press-fitting unit structure in which power device strings are placed vertically, which is applied to internal devices of relatively large power multi-level power units (such as IGCT, diodes, silicon controlled rectifiers, etc. etc.) mechanical press-fit structure. Background technique [0002] In the high-power power electronic conversion system, considering various reasons such as heat dissipation and electromagnetic compatibility, planar power electronic devices are mostly used. Due to its own characteristics, it needs to apply external force to the surface of its cathode and anode, and ensure that the pressure value is limited within a specific range, and the surface force is balanced, so that its electrical performance can reach the best working state. Therefore, during product design and system installation, it is necessary to make th...
