| titleOfInvention | Digital gas density relay having self-diagnosis function and self-diagnosis method of relay |
| abstract | Disclosed are a digital gas density relay having a self-diagnosis function and a self-diagnosis method of the relay. The relay comprises a gas density detection sensor, an intelligent control unit, an annunciator, a communication module, a normally-open electric control valve, and a normally-closed electric control valve; one end of the normally-open electric control valve is provided with an interface communicated with an electrical device, the other end of the normally-open electric control valve is communicated with one end of the normally-closed electric control valve, the other end of the normally-closed electric control valve is communicated with air, and the gas density detection sensor is provided on a gas path between the normally-open electric control valve and the normally-closed electric control valve; the intelligent control unit is connected to the gas density detection sensor, the annunciator, the communication module, the normally-open electric control valve, and the normally-closed electric control valve, respectively, so as to complete on-line monitoring of the gas density value of the electrical device and control the annunciator to control switching of the on-off states of the normally-open electric control valve and the normally-closed electric control valve. According to the present application, online self-inspection or self-diagnosis is completed while the gas density of the gas-insulated or arc-extinguished electrical device is monitored, no maintenance is required, operation and maintenance costs are reduced, and safe operation of a power grid is guaranteed. |
