The heating tube power calculation method and calculation formula, the heating tube is a process of converting electric current into energy. There are three wiring methods for heating pipes. The commonly used wiring methods include three-wire wiring and star wiring. The power of commonly used heating pipes is 380V and 220V. The corresponding wiring methods are different for different powers. The power calculation methods are different for different wiring methods. Everyone introduces the power calculation formula of the heating tube in detail.
Heat tube power calculation formula:
The heating tube is a pure resistance load, its power = voltage × current
The relationship between active power and current and voltage in a single-phase AC circuit is: P=U×I
This formula can be written as: W=V×A when used in a pure resistance circuit
formula:
W-the calculation unit of active power P;
V-the calculation unit of voltage;
A——The calculation unit of current.
The relationship between the current and power of the three-phase four-wire 380/220 symmetrical pure resistance load is:
P=I÷1.44 / I=P×1.44
The formula for calculating the power of the triangular connection of the heating tube:
Current intensity: I=U/R=380/18=21.1 Ampere;
Total power: P=3*U^2/R=3*380*380/18=24066.7 watts.
Heating tube star connection power calculation formula:
Current intensity: I=U/R=220/18=12.2A;
Total power: P=3*U^2/R=3*220*220/18=8066.7 watts.
If the rated voltage of the heating tube is 380 volts, then the above two connection methods can be used; if the rated voltage of the heating tube is 220 volts, then only the star connection method can be used.
