Description

Technical Field

[0001] The invention relates to the technical field of helium mass spectrometer leak detection for conductor components, and in particular to an automatic leak detection tooling system for a multi-channel quick-disassembly rigid cable component. Background Art

[0002] Electrical penetrations, as channels for various cables to penetrate the pressure boundaries of radioactive operating spaces such as nuclear power plant walls, research reactor walls, hot chamber walls, glove boxes, etc., must not only meet relevant electrical performance requirements, but also ensure reliable sealing performance. Even under harsh working conditions such as high temperature, high pressure, high humidity, high radiation, high corrosion, and earthquake accidents, they can still maintain electrical continuity and the integrity of the pressure boundary to prevent the leakage of radioactive materials. Conductor components are key components of electrical penetrations and play a key role in the sealing performance of the electrical penetration body.

[0003] Therefore, for conductor components, after they are assembled and formed, they must be tested for sealing performance in accordance with design requirements. When testing the sealing performance of conductor components, a leak detection tool is usually required. The commonly used leak detection tool is simple and can realize leak detection work, but it can only realize manual detection of one conductor component at a time. According to long-term detection operations, the current leak detection tool has the following shortcomings: (1) Only one conductor component can be detected at a time, and multiple conductor components cannot be detected at the same time. (2) The detection work is basically manual operation, the installation structure is complex, the disassembly and assembly process is cumbersome, the operation time is long, and the detection process takes a long time. (3) The detection efficiency is low, and the detection task cannot be completed on time when the conductor components are mass-produced. Summary of the invention
