380V heating tube wiring diagram wiring method, three electric heating tubes are connected to the triangle connection method, the triangle connection method of the motor needs to be divided into the head and the tail end, and the electric heating does not need to be divided. But one thing is that the rated voltage of the electric heating tube is 380V. Connect with Y connection. Let’s take a look at the correct wiring method of the heating tube in the example, and attach the wiring diagram.
220V 380V heating tube wiring diagram
Most of the heating tubes are connected in a star shape. The connection of multiple heating tubes is to connect one end of the three groups of heating tubes to zero, and the other end is connected to the ABC three-phase power supply. Then the working voltage of each group is 220V, and 220V heating tubes can be used. In the delta connection method, the two ends of the heating tube are respectively connected to one end of the other two heating tubes to form a triangle shape, and each connection is connected to a three-phase power supply of A, B, and C. The triangle connection can only be used for 380V heating tubes.
Star connection is a connection method between three-phase AC power supply and three-phase electrical appliances. Connect the ends, X, Y, and Z of the three windings of the three-phase power supply to form a common point O, and draw three end wires from the start ends A, B, and C. It is a system in which three sinusoidal power supplies with the same frequency, the same amplitude, and the phase difference of 120° are connected in a certain way to supply power to the outside.

The circuit that reaches the user often involves two voltages of 220V and 380V, requiring three phase wires and one neutral wire to form a three-phase four-wire system. In order to avoid electric shock accidents caused by electric leakage, users also need to add a ground wire. At this time, there are three phase wires, a neutral wire and a ground wire, so there is also a three-phase five-wire system.

380V heating tube wiring diagram wiring method content is here, although there are two heating tube wiring, but we only need to remember that 220V uses the star connection method, 380V uses the delta connection method.
