Is There A Positive And Negative Connection For Ac Reactor Wiring?

AC Reactors wiring generally has no positive and negative distinction. However, it should be noted that although there is no strict positive and negative requirement for reactor wiring, certain rules and precautions must still be followed in actual wiring.

‌Wiring method‌: The wiring method of the reactor needs to be determined according to the specific needs of the system, including single-phase wiring, three-phase wiring, and star/delta wiring. In a three-phase system, each three-phase capacitor is equipped with a reactor, and when the three phases are installed in parallel, the direction of the incoming and outgoing lines of the reactor needs to be paid attention to. The wiring direction of the intermediate phase must be opposite to the wiring direction of the two side phases to ensure the balance and stability of the system.
‌Terminal identification‌: Some reactors will indicate the incoming and outgoing lines on the wiring terminals, such as U1, V1, and W1 for incoming lines, and U2, V2, and W2 for outgoing lines. When wiring, the connection should be made according to these markings to ensure the correctness of the wiring.
‌Ground connection‌: The grounding connection of the reactor is also very important to ensure the safety and stability of the system. When grounding, it is necessary to use an appropriate grounding resistor and select the value of the grounding resistor according to the requirements and standards of the system. At the same time, a grounding current monitoring device can also be installed to monitor the changes in the grounding current in real time and trigger an alarm or protection action when it exceeds the set threshold.

In summary, although there is no strict positive and negative distinction in the wiring of AC reactors, certain rules and precautions must still be followed when wiring to ensure the normal operation and safety and stability of the system.
