Abstract

The invention provides a composite busbar insulation supporting device and an IGBT power module. The composite busbar insulation supporting device comprises a strip-shaped insulation supporting body, wherein a plurality of bosses are arranged on the upper surface of the insulation supporting body at intervals, the bosses are provided with nut installation countersinks and bolt blind holes, and the two ends of the insulation supporting body are provided with installation lugs which are provided with installation holes for installing the IGBT power module. By means of the composite busbar insulation supporting device and the IGBT power module, due to the fact that the bosses are arranged on the strip-shaped insulation supporting body, and the nut installation countersinks and the bolt blind holes are formed in the bosses, the nut installation countersinks and the bolt blind holes can be used for electrically separating bolts and nuts used for fastening the composite busbar, electric safety of the IGBT power module is improved, the insulation supporting body can support the interface of the composite busbar and prevent the composite busbar from deformation due to stress.

Description

technical field [0001] The invention relates to converter technology, in particular to a composite busbar insulation support device and an IGBT power module. Background technique [0002] With the development of AC drive technology for electric locomotives, converters using high-frequency and high-power Insulated Gate Bipolar Transistor (IGBT) power modules as switching elements are increasingly used. [0003] Since the input and output voltage and current of the composite busbar of the IGBT power module to the external high-voltage interface are large, and the composite busbar interface of the IGBT power module must be firmly connected with the composite busbar interface of the converter cabinet, the two composite busbars are connected. After tightening, the bolts and nuts used to fasten the butt are charged. The existing IGBT power modules do not provide insulation protection and mechanical support for the bolts and nuts. Therefore, the electrical safety of the IGBT power...
