System for irradiation test of bipolar device in hydrogen atmosphere

The utility model relates to a system for an irradiation test of a bipolar device in a hydrogen atmosphere. The problems that most of existing hydrogen soaking cavities adopt glass tubes, the cavities need to meet the high-vacuum requirement and are limited by material characteristics, and the size of the irradiation cavities is very small; the existing hydrogen soaking device is simple in structure and does not have the function of realizing electric connection between a device in a cavity and an external source meter; comprising a metal irradiation cavity, a vacuum pump, a gas filling assembly, a fixing support and an airtight aviation connector. The metal irradiation cavity comprises a cavity body; the vacuum pump is communicated with the chamber body; the gas filling assembly is communicated with the chamber body; the fixed bracket is arranged in the chamber body; a first window, a second window and a first through hole are formed in the chamber body, a glass cover plate is hermetically mounted on the fir
