AI Technical Summary

Technical Problem

Under the high pressure environment of the deep sea, underwater connectors may experience partial discharge due to tiny air gaps at the mating interface, which can lead to accelerated carbonization, cracking, and aging of the rubber material, threatening power supply safety and operational reliability.

Method used

An underwater connector was designed. By setting an outer bladder in the plug assembly to form a sealed cavity, filling it with an insulating medium, and using the flow channel of the plug housing to guide the insulating medium into the tiny air gap at the mating interface, the electric field concentration caused by the difference in dielectric constant is eliminated, and partial discharge is suppressed.

Benefits of technology

It effectively avoids insulation breakdown and short circuit faults, improves the insulation performance and sealing stability of underwater connectors, and ensures the reliability and safety of long-term operation.
