For low-power three-phase submersible pumps, is the cause of damage related to wiring? If there is, how could it cause damage?
Single-three-phase dual-use micro submersible pump motor, including one three-phase AC contactor, two two-phase AC contactors, one three-phase switch, one two-phase switch, two push-button toggle switches, at least one capacitor, and a micro pump or motor; The connection method is such that the terminals of the 220-volt AC contactor C1 are connected to the wires 4, 5, and 6 of the motor, and it is also connected to the three-phase power switch ; Connect the motor leads 1, 2, and 3 to the lower terminals of the post; connect the coil to a 220-volt power supply, and connect it to the lower terminals of the AC contactor C2. The upper terminals of the AC contactor C2 are connected in parallel with each other ; The upper terminal of AC contactor C3 is connected to the 220-volt power switch, while the lower terminal is connected to two of the wires belonging to motors 1, 2, and 3. The other lower terminal of AC contactor C3 is connected to a capacitor; the other end of this capacitor is connected to one of the wires belonging to motors 1, 2, and 3 ; One end of the 380-volt switch KK1 is connected to the 380-volt power supply, while the other end is connected to the coil of the AC contactor C2 ; The other end of the coil of AC contactor C2 is connected to a 380-volt power supply, while one end of the 220-volt switch KK2 is connected to a 220-volt power supply; the other end of KK2 is connected to the coil of AC contactor C3, and the other end of that coil is also connected to a 220-volt power supply. If the wires are connected incorrectly, it can damage the submersible pump; it may even burn out the motor!
