Embodiment Construction
[0036] Such as figure 1 Shown, SF 6 The gas leakage online monitoring and alarm system is composed of the connection between the field end and the remote end through the RS485 bus; the field end includes,
[0037] Ultrasonic measurement module, installed in the SF 6 In the substation of electrical equipment, the ultrasonic velocity measurement method is used to measure the propagation speed of the ultrasonic wave through the ultrasonic sensor, and the SF is deduced in reverse. 6 Gas content, used to measure SF in air 6 Concentration of leakage gas, which is connected with ARM controller;
[0038] Infrared measurement module, installed in the SF 6 In the substation of electrical equipment, it measures the gas composition in the substation based on the principle of infrared absorption, and analyzes whether there is SF 6 Gas leaks for measuring SF in air 6 Concentration of leakage gas, which is connected with ARM controller;
[0039] Temperature measurement module, install...
