1. Air circuit breaker is an active electrical appliance that can not only touch and disconnect the circuit normally, but also operate under abnormal conditions such as overcurrent, reverse current, short circuit and loss (under)voltage. Its primary role is to maintain the electrical equipment in the AC and DC circuits, and it can also operate the circuits infrequently. It is used to quickly block the frequency converter governor and avoid power supply problems caused by line problems.
2. The communication reactor, also known as AC reactor and communication reactor for power supply coordination, is primarily used to avoid harmonic disturbance in the power grid.
3. The communication touch device is referred to as the touch device, which is used to shield the AC and DC circuits that are turned on and off at a long distance, or the active electrical appliances of the large capacitance control circuit, which is mainly used for the frequency conversion governor when it is faulty, actively intercept the main power supply and avoid power failure and failure to start again.
4. The radio noise filter, also known as the power filter, is primarily used to conduct radio signals from the metal pipeline to the equipment, or to conduct the disturbance signal from the disturbance source equipment through the power supply.
5. The DC reactor is mainly to press the higher harmonics generated by the frequency conversion governor, and its role is better than that of the communication reactor.
6. The output communication reactor is also known as the output side anti-disturbance filter, which is a filter that affects the power supply side by pressing the high-frequency disturbance filter.
7. The filter hood is mainly to prevent dust from entering the frequency converter.
