| titleOfInvention | An online detection and alarm device for sulfur hexafluoride gas leakage |
| abstract | The utility model proposes an on-line detection and alarm device for sulfur hexafluoride gas leakage, which includes a power supply, a single-chip microcomputer, an alarm, a display, a fan control circuit, an oxygen sensor and an A/D conversion circuit, and also includes a multi-channel temperature and humidity detection circuit. And multi-channel sulfur hexafluoride detection circuit; sulfur hexafluoride detection circuit includes ultrasonic transmitting circuit and ultrasonic receiving circuit; power supply, alarm, display, fan control circuit, temperature and humidity detection circuit, A/D conversion circuit, ultrasonic transmitting circuit The ultrasonic receiving circuit and the ultrasonic receiving circuit are respectively electrically connected to the single chip, the oxygen sensor is electrically connected to the A/D conversion circuit, and the ultrasonic transmitting circuit is wirelessly connected to the ultrasonic receiving circuit. The ultrasonic transmitting circuit and the ultrasonic receiving circuit have simple structure, low cost and high practicability; the whole device can detect whether SF6 gas leakage occurs and the position of SF6 gas leakage, and can also detect multi-channel temperature and humidity. The circuit structure is simple and the cost is low. |
