How to connect the electric immersion heating tube for water tank correctly?

The electric immersion heating tube for water tank will form different wiring methods because of different equipment voltages. In normal electric heat pipe heating equipment, triangle wiring and star wiring are used more often. Let the electric heating tube do the heating for the device. Common electric tube voltages are 24V, 48V, 110V, 220V and 380V AC voltages. 380V three-phase four-wire power supply line, the voltage between any two live lines is 380V, and any neutral line and live line can be composed of 220V. It’s worth thinking about how to properly wire electric tubular heating element? Here it is said that there are two commonly used wiring methods of stainless steel heating tube, triangle connection and star connection.

1. Triangle connection method. The first end of each component of the immersion flange heating tube is connected to the end of another component, and the three contact points are connected to three phase wires respectively. The rated voltage of the electric heat pipe is 380V, first the three electric heat pipes are connected in a ring, and then the three fire wires of 380v are connected to the three joints of the electric heat pipe. The triangular connection method has a characteristic: the rated voltage of the three flange heating tube elements is 380 volts, if the resistance values of the three elements are different, it will not affect the feasibility of this connection, and the triangular connection method is three times the power and current of the star connection method.

2. Star connection method. The heating element of three electric immersion heat pipes connects the first end of each element together, and the three ends are respectively connected with three phase wires. The rated voltage of the electric heat pipe of the star connection method is 220V. First connect one end of the three electric heat pipes together, and then connect the other end to the three fire wires of 380v respectively. The characteristic is that when the rated voltage of the three components is 220 volts, if the resistance values of the three components are not the same, the neutral point should be connected to the neutral line.
