Embodiment Construction

[0019] The following describes the embodiments of the present invention in detail with reference to the accompanying drawings; it should be noted that this embodiment is narrative and not restrictive, and the protection scope of the present invention cannot be limited by this.

[0020] This embodiment takes an IGCT power cell string as an example for description.

[0021] A power device string vertically placed mechanical pressing unit structure, including a square frame 1, a top plate 5, a bottom plate 7 and a power device string 3. The bottom plate is fixed at the bottom of the square frame, and the top plate is fixed at the upper end of the square frame , The bottom plate and the top plate are arranged in parallel, and a plurality of power device strings and other auxiliary parts 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 that require mechanical pressing, in particular to a power device string vertically placed mechanical pressing unit structure, which is applied to the internal devices of higher-power multi-level power units (such as IGCT, diodes, thyristors) Etc.) mechanical pressing structure. Background technique [0002] In high-power power electronic conversion systems, considering many reasons such as heat dissipation and electromagnetic compatibility, flat-panel power electronic devices are mostly used. Due to its own characteristics, it is necessary to apply external force to the surface of its cathode and anode, and to ensure that the pressure value is limited within a specific range and the surface is balanced in order to achieve the best electrical performance. Therefore, during product design and system installation, the mechanical press-fitting structure of the unit needs to be reasonable to ensure that the ...
