Modular multi-cable via hole insulation and sealing structure based on pressure compensation

Abstract

A modular multi-cable through-hole insulation and sealing structure based on pressure compensation, including: a high-voltage transition section set on the high-voltage side, a low-voltage transition section set on the low-voltage side, and several decompression modules arranged in series therein. The transfer section includes a high-voltage transfer bracket and a high-voltage transfer base with a high-voltage transfer conductor post inside it; the low-voltage transfer section includes: a low-voltage transfer base with a low-voltage transfer conductor post; the decompression module includes : The decompression module bracket and the decompression module base with the decompression module conductor post arranged inside it, the high-voltage transfer conductor post, the decompression module conductor post and the low-voltage transfer conductor post are connected in sequence, the high-voltage transfer bracket, the high-voltage The transfer base and the decompression module base form a high-pressure transfer chamber, and the decompression module base, decompression module support and pre-stage decompression module base form a decompression module chamber. The invention realizes simultaneous sealing and mutual insulation of multiple cables, and has a simplified structure and small size, and the sealing module can be adjusted according to requirements and has pressure compensation.

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...
