Three-phase power supply connection method of flange electric heating tube and stainless steel electric heating tube

What are the main three-phase power connection methods for flange electric heating tubes and stainless steel electric heating tubes?

Electric heating tubes, as electric heating elements that convert electrical energy into heat energy, are widely used in various industries and household appliances. The quality of the electric heating tube directly affects the quality of the product, so you must be careful when selecting the electric heating tube. It is very necessary to choose an electric heating tube of good quality as much as possible. As the saying goes, you get what you pay for. We advise our customers not to be cheap and avoid purchasing inferior products. What are the main three-phase power connection methods of electric heating tubes and stainless steel electric heating tubes? Let’s take a look below.

For three-phase voltages in star connection, the phase voltage is three times the root of the phase voltage, and the line current is equal to the phase voltage. When the three-phase load is balanced, even if the neutral wire is connected, no current will flow through it. When the three-phase load is unbalanced, the neutral line should be connected, otherwise the voltage dividing circuit of each phase load will be different. For the three-phase voltage in delta connection, the phase voltage is equivalent to the phase voltage, and the line current is equivalent to three times the root of the phase voltage.

  The triangle connection method of the three-phase voltage of the electric heating tube is to connect each phase switching power supply or load end to end, and lead out each connected point as the three live and neutral lines of the three-phase voltage. There is no neutral wire in the delta connection, and the neutral wire cannot be drawn out, so there is only a three-phase three-wire system. After adding the ground wire, it becomes a three-phase four-wire system.

  For star connection, the center of the circle (called the neutral line) can be drawn out as the neutral line, forming a three-phase four-wire system. It does not lead to a three-phase three-wire system. Of course, whether there is a neutral wire or not, a ground wire can be added to form a three-phase five-wire system or a three-phase four-wire system.

  The three-phase power connection methods of electric heating tubes and stainless steel electric heating tubes mainly include star connection and delta connection. The conditions for use are determined based on the rated phase voltage when the heating tube is made.

The star connection method of the three-phase voltage of the electric heating tube is to connect one end of each phase switching power supply or load to one point, and their other ends are used as the transformer ground wire, each of which is the three live and neutral wires of the three-phase voltage.
