The degree of mechanical ammeter is four digits, and the maximum display number is 9999 degrees.
If it exceeds, it means that 1 10,000 kWh has been used. The counting wheels all return to zero, which means that 10000 kwh has been used.
Extended data:
The degree of mechanical ammeter is four digits, and all digits show 9, which means that all characters have reached the maximum number, and a metering cycle is completed. The reading should add 10000 degrees to the number displayed later. For example, it shows 359 degrees, and the actual electricity consumption is 10359 degrees.
Watt-hour meter is an instrument for measuring electric energy, also known as watt-hour meter, fire meter and watt-hour meter, which refers to an instrument for measuring various electric quantities.
When using the electric energy meter, it should be noted that under the conditions of low voltage (below 500 volts) and small current (tens of amperes), the electric energy meter can be directly connected to the circuit for measurement.
In the case of high voltage or high current, the watt-hour meter cannot be directly connected to the line, and it needs to be used with voltage transformer or current transformer.
Electronic watches are used now, and mechanical watches have basically been eliminated.
With the rapid development of China's economy, the demand for electricity from all walks of life is increasing, and the phenomenon of unbalanced electricity consumption in different periods is becoming more and more serious.
In order to alleviate the increasingly sharp contradiction between power supply and demand in China, adjust the load curve and improve the imbalance of power consumption, the time-of-use electricity price system between peak and valley is fully implemented, and "peak shaving and valley filling" is implemented.
In order to improve the efficiency of electricity consumption in China and make rational use of power resources, the power departments of some provinces and cities in China have gradually introduced multi-rate watt-hour meters to charge users' electricity consumption according to time.
