Remote control cabinet

The control cabinet shall install switch tools, instruments, protective appliances, and auxiliary devices in enclosed or semi enclosed metal cabinets or screens according to electrical wiring standards. The layout shall comply with the standards for normal operation of the power system, facilitate maintenance, and not endanger the safety of personnel and surrounding equipment

The low-voltage units, relays, and contactors of the control cabinet are protected by fuses; When the connection between the frequency converter and the motor exceeds 100m, the power supply capacity of the frequency converter is greater than 600kW/A, or the power supply capacity is greater than 10 times the capacity of the frequency converter, it is recommended to increase the input-output reactance

Ensure that the contactors inside the control cabinet have arc extinguishing function. The AC contactor adopts an AC suppressor, and the DC contactor adopts a flywheel diode installed in the winding. Using a variable resistor is also effective

There are various types of control cabinets, including electrical control cabinets, frequency conversion control cabinets, low-voltage control cabinets, high-voltage control cabinets, pump control cabinets, power control cabinets, explosion-proof control cabinets, elevator controllers, PLC control cabinets, fire control cabinets, brick machine control cabinets, etc

During normal operation, the circuit can be connected or disconnected through manual or automatic switches. When a malfunction or abnormal operation occurs, use protective devices to cut off the circuit or sound an alarm. According to the measuring instrument, some parameters during operation can be displayed, and various electrical data can be adjusted to remind or signal deviations from normal working conditions. Commonly used for power generation, distribution, and substations
