By converting the energy and kinetic energy of water into electric energy, hydropower station has created great social and economic value. Hydropower is a kind of green, renewable and clean energy, which originates from nature. Therefore, hydropower stations based on hydropower can also be said to have no cost and profit, so it is not surprising to be called money printing machine. What kind of instruments are used in hydropower stations?
First of all, all kinds of sensors and meters are indispensable for hydropower projects, such as pressure sensors, temperature sensors, liquid level sensors and other advanced sensors and meters twenty-four The whole hydropower station is monitored continuously for hours to master the operation of each generating unit in real time.
Secondly, measuring instruments. For the measurement of reservoir water level, water level of water collecting well, pressure difference of trash rack, pressure difference of penstock and other data, accurate data can ensure that every unit of hydropower station can operate well, reduce daily maintenance workload as much as possible, and improve the safety and reliability of hydropower station, which is the key point of any project. For the measurement of liquid level change, the most important liquid level and flow measurement instruments are electromagnetic flowmeter Sometimes the proportion of flowmeter and level gauge in the whole hydropower project is very small, but it is very important for the operation of the whole power station.
Finally, various auxiliary instruments. Digital display meter, flow totalizer, transmitter, thermometer, flow switch, pressure switch, etc. The main function of these instruments is to monitor and protect some parameters, such as pressure, flow, temperature and so on, for the auxiliary system of hydroelectric generating units.
For the whole hydropower station, these instruments and meters only account for a small part. The whole huge hydropower system is composed of numerous different components. Only by performing their own duties and cooperating closely can the stable operation be achieved.
