Insulation status online monitoring system of sulfur hexafluoride inflatable-type current transformer

The utility model discloses an insulation status online monitoring system of the sulfur hexafluoride inflatable-type current transformer, which is characterized in that: a first switch electromagnetic valve is connected with a stabilizing valve, the output end of the stabilizing valve is connected with an infrared sensor and an electrochemical sensing device, the electrochemical sensing device is connected with a pressurizing pump through a second switch electromagnetic valve, the pressurizing pump is connected with a pressure adjusting valve, the pressure adjusting valve can be communicated with a transformer gas compensation port, and the first switch electromagnetic valve can be communicated with the transformer gas compensation port. Due to the adoption of the insulation status online monitoring system, the online monitoring can be realized, the real-time performance is strong, the sample gas after being detected can be sent back to the inflatable current transformer, and the gas loss and the air pollutio
