How is the three-phase oven connected?

How is the three-phase oven connected?

Answer:

Whether in a three-phase oven or a single-phase oven, the heating element is usually 220 volts.The three-phase oven uses 220 volt electric heating element and adopts star connection. 3 phase line terminals, three phase lines, 1 zero line terminals, zero line, a total of 4 lines. The ground wire of the three-phase five wire power supply is borrowed from the oven shell.
Three phase five wire electric oven, heating element is three-phase star connection method, three FireWire, neutral point, zero line, ground wire, casing case, a total of five lines!You can put the three-phase FireWire three lines into the line, zero line and ground wire together, then connect the power ground wire, the casing will be out of power!
After the power, the machine leakage everywhere is very serious, if there is no connection error, that is true leakage.This is dangerous. First, look for the insulation resistance of the test line, the terminal of the test line, the terminal to the shell (not less than 1 euro), or find the multimeter to test whether the terminal of the phase line is connected to the shell, if you connect with China, you must find out the location.
