Abstract: |
The present invention relates to an IGCT inversion circuit compression joint uniformity checking measure of high-voltage frequency converter and its testing method, belonging to the field of IGCT high-voltage frequency converter manufacture technology. It is characterized by that in the compression joint process said invention adopts pressure test paper to really check pressure distributed condition, and utilizes the pressure test paper colour distributed condition to judge that said pressure distribution is uniform or not and regulate compression joint direction again. Said invention can reliably ensure the compression joint quality of IGCT inversion circuit of high-voltage frequency converter. |
