Multiple cables are sealed at the same time, mutual insulation is achieved, the structure is simple, the size is small, the sealing module can be adjusted according to needs, and pressure compensation is achieved.

Description

technical field [0001] The invention relates to a technology in the field of high-voltage equipment, in particular to a pressure compensation-based modular multi-cable through-hole insulation and sealing structure. Background technique [0002] In the industrial production and scientific research experiments involving high-pressure pressure vessels, many power supply or sensor signal cables are generally arranged in the vessel, and the design of the through-hole sealing structure of these large numbers of cables from the high-pressure side to the low-pressure side is very important. Taking the high-pressure thermal-hydraulic experiment as an example, in order to obtain detailed and high-precision experimental data, it is necessary to arrange a plurality of various sensors in the test section. The through-hole sealing structure design of numerous cables composed of control / output signal lines of sensors is one of the main difficulties in the design of thermal-hydraulic experi...
