1, frequency control cabinet switching power supply conversion and maintenance functions
Frequency control cabinet general design program has isolation switch components, which is connected to the three-phase five-wire switching power supply, can assist the frequency control cabinet for power circuit conduction operation, and can be presented in the power circuit and soft starter short circuit failure or load maintenance. In addition to the frequency conversion cabinet can also be disconnected from the switching power supply in the motor maintenance to ensure the safety of the operating staff.
2, inverter control cabinet manipulation function
Frequency control cabinet door design program has a display system and operation control panel, which is connected with the internal electrical components of the frequency control cabinet, can visualize the display of information frequency control cabinet operation, in addition to facilitate the operation of staff to manipulate the operation of the DC frequency conversion equipment, and the motor and other controlled systems to carry out on-the-spot operation.
Variable frequency control cabinet door, also installed a variety of instrumentation and indicators, such as ammeter, ammeter, frequency meter, and switching power indicator, alarm indicator, operation indicator, DC indicator and so on. Frequency control cabinet operation and operation, can be immediately reflected in the various types of instrument panels and indicators, to complete the soft starter operating status of the moment detection.
3, frequency control cabinet DC frequency conversion function
Frequency control cabinet operation panel is set with DC frequency conversion with the resistor, can be based on the operating staff's output frequency, to the motor transport command data signal, manipulate the motor speed ratio. Some of the products in the frequency control cabinet are set with DC conversion function to ensure that the motor is converted back to DC switching power supply according to the fully automatic control circuit in the event of common faults of the soft starter.
4, inverter control cabinet safety precaution function
The frequency conversion control cabinet centralizes all kinds of electrical components including soft starters in the cabinet body, which can reduce the level of harm of environmental factors to electrical components, reduce the level of air pollution of electrical components, and also reduce the risk of electrocution accidents of the staff operating the frequency conversion control cabinet, and thus has a good safety precautionary effect.
