The heating tube wiring method. The heating tube generally converts electric energy into heat by electric heating. The heating tube can be seen everywhere nowadays. There are many kinds of household products such as common microwave ovens, electric ovens, electric water heaters, and other products. Energy is generated by converting electrical energy into thermal energy. So we don't know much about the heating tube. The common wiring methods of the heating tube are series, parallel, star connection, and delta connection. The following editor will explain these four wiring methods in detail.
One, series connection
Series wiring diagram
series connection is one of the basic ways of linking electric heating elements. The heating tube is connected one after another end to end, and the method used in series is called a series circuit.
Two, parallel
Parallel wiring diagram
Parallel connection is a connection method that connects the first and the first phase of the electric heating tube, and the tail and tail phases at the same time, that is, a parallel circuit.
A. The total voltage in the parallel circuit is equal to the voltage of each branch
B. The total current in the parallel circuit is equal to the sum of the currents of each branch
c. The total resistance in the parallel circuit is equal to: 1/Rtotal=1/(1/R1+1/R2+1/R3+……+1/Rn), that is, the reciprocal of the total resistance is equal to the sum of the reciprocal of each sub-resistance. If n equal resistors are connected in parallel, the formula is simplified to R and = R/n
D. The total power in the parallel circuit is equal to the sum of the power of each branch. The electric heating tubes are connected in the same circuit, but connected by different wires, causing the two to not affect each other, and an open circuit will not affect the other.
Three, triangle connection:
Delta wiring diagram
A. Delta connection: the first end of each element of the electric heating tube is connected to the end of another element, and the three contacts are respectively connected to the three phase wires;
B. The characteristics of the delta connection method: the rated voltage of the three electric heating tube elements is 380 volts; if the resistance values of the three elements are different, it does not affect the feasibility of this connection method. The power and current of the delta connection are three times that of the star connection.
Four, star connection:
Star wiring diagram
A. Star connection method: the heating elements of three electric heating tubes, the head end of each element is connected together (this point is called the neutral point), and the three tail ends are respectively connected to three phase wires.
B. When the rated voltage of the three components is 220V; if the resistance values of the three components are different, the neutral point should be connected to the neutral line.
Heat pipe wiring precautions:
If it is a heating tube with a rated voltage of 220V, it needs to be connected to a 380V circuit, and a star connection is required.
If it is a heating tube with a rated voltage of 380V, it needs to be connected to a 380V circuit, and a delta connection is required.
If it is a heating tube with a rated voltage of 380V, the rated power of the heating tube cannot be reached if the star connection method is used. The actual power is about one third of the original rated power (220*220)/(380*380).
The content of the heating tube wiring method is here. I hope to help everyone. The heating tube and the electric heating tube have the same function, but the method of calling is different. The wiring method of the heating tube, the electric heating tube and the heating tube can be used. The above four methods.
