Description

Automatic alarm air cooler real-time supervision device that leaks
Technical Field
The utility model relates to the technical field of air coolers, in particular to an automatic alarm real-time water leakage monitoring device for an air cooler.
Background
At present, the temperature of the stator coil and the iron core can be gradually increased due to the characteristics of high working voltage and high current of the hydroelectric generating set and the heating effect of unavoidable copper loss and iron loss. The temperature is too high to cause insulation ageing and even damage of an insulation layer, and meanwhile, the insulation ageing speed is accelerated under a high-temperature environment, and the service life of equipment is greatly shortened. Through continuous circulation, the stator winding and the rotor winding of the generator are cooled, and the temperature is kept within the range required by the regulations.
After the air cooler runs for a long time, because the internal environment of the wind tunnel of the generator is complex, the unstable water flow area in the heat dissipation copper pipe is easy to wear and further leakage is caused. Because the air cooler is arranged on the outer side of the stator, the air cooler leaks water to cause insulation damage and breakdown of the stator bar, so that the safe and stable operation of the hydroelectric generating set and the power grid system is seriously threatened, and a large amount of direct and indirect economic loss can be caused. Therefore, the detection of the running and leakage conditions of the air cooler is a great focus of the work of the running management personnel of the hydropower station at present.
At present, the leakage condition of the air cooler is monitored mainly by means of two modes of alarm and manual inspection of a monitoring system.
And (3) alarming by a monitoring system: and (3) sending data such as inlet and outlet pressure, flow and the like of the air cooler in operation to a power station monitoring system in a hard-wired mode through a conventional meter such as a pressure meter and a flow meter, displaying each measured value in real time, and sending an alarm signal by the monitoring system when each measured value exceeds the upper limit and the lower limit, so as to remind operators of checking and processing on site.
Manual inspection: through daily equipment inspection of operators, the running state of the air cooler equipment is directly observed, and whether the air cooler leaks or not is judged.
The air cooler leakage defect is found to have certain hysteresis through the monitoring system alarm, because the monitoring system is used for ensuring the working efficiency of the monitoring staff, a large amount of interference of useless signals is avoided, when the leakage condition is not obvious, the pressure and flow change does not reach the fixed value set by the monitoring system, the monitoring system can not generate an alarm signal, when the alarm signal appears, the air cooler leakage condition is often developed to a serious step, and the processing difficulty of operation management staff is greatly increased. Meanwhile, the changes of the air cooler flow and inlet and outlet pressure are affected by the running condition of the unit, the water supply running condition of the unit technology and the like, and the leakage condition cannot be completely, accurately and intuitively reflected.
The mode of finding the leakage of the air cooler through manual inspection has certain requirements on the experience of inspection personnel. Meanwhile, most hydropower station inspection is fixed shift inspection at present due to manpower configuration limitation, the running state of the air cooler cannot be monitored all the day, the leakage problem of the air cooler cannot be timely found at the first time, and the best opportunity of accident handling or early intervention is missed.
