Color developing pre-warning device for real-time monitoring of insulation gas decomposition products of SF6 power equipment

Abstract

The invention discloses a color developing pre-warning device for real-time monitoring of insulation gas decomposition products of a SF6 power equipment, which comprises a stainless steel shell. The stainless steel shell is provided with two glass explosion-proof color developing pipes inside and observation windows at the two sides. The stainless steel shell is provided with a connecting head atthe top end and a circle of guide rail at the inner wall of the bottom. The front end of the guide rail is fixedly provided with a baffle with air holes. The guide rail is provided with a sheet inside. The back side of the sheet is connected with at least one spring. The other ends of the springs are arranged on a pressure sensor. The rear side of the pressure sensor is connected with a controller. The rear side of the controller is connected with a power supply. The rear side of the power supply is connected with a rotating indicator lamp. A transparent tempered glass is arranged on the position facing the rotating indicator lamp of the bottom of the stainless steel shell. The device can capture the fault traces and accurately locate the defects after installation.

Description

technical field [0001] The invention relates to the technical field of insulation monitoring of gas insulation equipment, in particular to a color early warning device for real-time monitoring of insulation gas decomposition products of SF6 power equipment. Background technique [0002] SF6 power equipment is widely used in the power industry, including GIS, circuit breakers and transformers, etc., and its insulating gas is SF6. When the equipment experiences overheating, discharge and other faults, the insulating gas undergoes an irreversible reaction to generate H 2 S, SO 2 Waiting for the decomposition products, detecting the content and type of the decomposition products has become a technical means for diagnosing latent faults and locating fault points. At present, the commonly used detection technologies are detection tubes, sensors, chromatography, and infrared instruments for on-site gas detection. Since the SF6 equipment is filled with a large number of adsorbents...

AI Technical Summary

Problems solved by technology

[0003] The invention solves the problems in the prior art that the fault diagnosis of SF6 equipment basically relies on after the event, the development of electrified detection is limited by the detection cycle and technical limitations, and the conventional sensor on-line detection technology is expensive and difficult to popularize, and provides a real-time monitoring SF6 Color warning device for insulation gas decomposition products of power equipment
