These primarily include circuit breakers, transformers, instrument transformers, lightning arresters, capacitors, disconnect switches, grounding switches, bushings, and busbars. SF6 gas is non-flammable and non-explosive, possessing both chemical stability and excellent electrical properties. Furthermore, the solid insulating material within it also possesses stable chemical properties and excellent insulation properties. Since the 1980s, SF6 electrical equipment has been widely used, and since the end of the last century, fully sealed combination electrical appliances insulated with SF6 gas have been put into widespread use.

Furthermore, some detection devices lack precise monitoring of gas flow and volume data, making effective control of the testing process difficult. Furthermore, insufficient power supply stability can affect the device's operation in various environments, and poor lighting conditions can also result in unclear images, hindering accurate gas analysis.

[0031] Next, the working principle of this embodiment is described in detail to enable those skilled in the art to better understand the present invention:

[0032] The control module is respectively connected to the power supply module, camera module, flow detection module, test solenoid valve, detection solenoid valve, light source and three-way solenoid valve; the power supply module is a switching power supply that provides electrical energy for the device; the test colorimetric tube and the detection colorimetric tube are transparent glass tubes with the same specifications; the test colorimetric tube plays a pre-test role. When performing a gas test, the SF6 gas in the electrical equipment is introduced into the test device through the air inlet interface, the three-way solenoid valve opens the valve on one side of the test colorimetric tube, the gas is introduced into the test colorimetric tube, the test solenoid valve is opened, and the gas flows out of the test colorimetric tube. The flow detection module detects the flow and volume data of the gas flowing through the test colorimetric tube, and transmits the data to the control module.

The camera module shoots the detection colorimetric tube, and the camera module transmits the image information of the detection colorimetric tube captured to the control module. The light source is an LED lamp, which is used to provide light for the camera module to shoot.

[0035] When the test solenoid valve or the detection solenoid valve is opened, the gas flows out from the test colorimetric tube and the detection colorimetric tube and passes through the outlet pipe. At this time, the flow sensor in the middle of the outlet pipe is used to detect the gas flow, providing more accurate data support for the detection process.

[0036] The working principle of this embodiment is the same as that of embodiment 1.
