Embodiment 1

[0019] Such as figure 1 As shown, a color early warning device for real-time monitoring of SF6 power equipment insulation gas decomposition products, including a stainless steel shell 1, two glass explosion-proof color tubes 2 are arranged inside the stainless steel shell 1, and the two sides of the stainless steel shell 1 An observation window 3 is provided for inspectors to observe the discoloration of the color display tube 2 to judge electrical faults. The top of the stainless steel shell 1 is provided with a connector 4 for connecting with gas-insulated equipment, so that the insulating gas in the SF6 equipment can be freely Diffusion into the device can realize the detection of SF6 gas decomposition products. There is a guide rail 5 on the inner wall of the bottom of the stainless steel casing 1, and a thin slice 7 is arranged in the guide rail. The thin slice 7 can slide in the guide rail 5, and the front end of the guide rail 5 is fixed. A baffle 6 is provided, and a l...

Abstract

The invention discloses a color warning device for real-time monitoring of the decomposition product of insulating gas of SF6 power equipment, which comprises a stainless steel shell, two glass explosion-proof color tubes are arranged inside the stainless steel shell, observation windows are arranged on both sides of the stainless steel shell, and the stainless steel shell There is a connector at the top, a guide rail is provided on the inner wall of the bottom of the stainless steel shell, the front end of the guide rail is fixed with a baffle plate with air holes, a thin piece is arranged in the guide rail, at least one spring is connected to the rear side of the thin piece, and the other end of the spring is set at the pressure On the sensor, the controller is connected to the back of the pressure sensor, the power is connected to the back of the controller, the rotation indicator is connected to the rear of the power supply, and a piece of transparent tempered glass is set on the bottom of the stainless steel shell facing the rotation indicator. After the device is installed, it can capture fault traces and accurately locate defects.

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...
