AI Technical Summary

Technical Problem

Existing traditional sensing technologies cannot achieve high-precision, real-time, and reliable monitoring of gas pressure and trace moisture content in GIS switchgear, resulting in insufficient detection accuracy, slow response speed, inability to provide timely warnings, and detection failure in closed, low-pressure environments.

Method used

A dynamic gas-driven insulating gas detection device is adopted, which generates an active airflow through an ultrasonic generator to drive the insulating gas to flow evenly. It integrates a status monitoring module and a main control acquisition board to realize the synchronous acquisition and compensation of multiple parameters, thereby improving the detection accuracy and stability.

Benefits of technology

It enables high-precision and stable detection of the insulating gas inside GIS switchgear, avoids measurement deviations caused by static media, supports real-time early warning and condition-based maintenance, and reduces operation and maintenance costs.

Abstract

The application discloses a dynamic gas driving type insulating gas detection device, and relates to the field of GIS switch equipment operation monitoring. The device is arranged in a GIS switch, a mounting opening is formed in the top of a shell, and the shell is fixed to an equipment mounting surface. A middle sealing opening divides a cavity into a sealed chamber and an open chamber through a sealing ring and a gland. An air inlet is arranged at the bottom. An ultrasonic generator is fixed in an ultrasonic fixing slot of the open chamber, and active air flow is generated through ultrasonic oscillation to drive insulating gas to flow. A state monitoring module is coaxially arranged on a sensor mounting table to collect state parameters such as temperature, humidity, pressure and micro water. A main control collection board is arranged in the sealed chamber. The ultrasonic generator and the state monitoring module are connected to the main control collection board through a communication cable passing through a gland sealing hole, so that dynamic gas driving and state monitoring are realized. The application forcibly drives insulating gas to uniformly flow through the arrangement of the ultrasonic generator, and the detection precision and stability of the insulating gas in the GIS switch equipment are improved.
