SKYT is here to talk about basic composition and working principle as followings:
The Basic composition of electrical control cabinet
1.Cabinet body
The cabinet body is the outer shell of the electrical control cabinet, normally made of metal material such as cold-rolled steel plate, which is made through bending, welding and other processes, and has good strength and stability. The surface of the cabinet will undergo rust and anti-corrosion treatment, and there will be corresponding protection levels depending on the usage environment.
2.Electrical parts
Electrical components come in a variety of forms, each carrying out specific tasks while cooperating to regulate and safeguard circuits. Circuit breakers, contactors, relays, fuses, frequency converters, PLCs, and so on are examples of common electrical components.
3.The electrical system
The cables and wires within the electrical control cabinet are arranged and categorized based on their voltage levels, functions, and other characteristics. They are connected to different electrical components in a neat and organized manner. Wires are typically fixed and protected using conduits, wire trays, and other techniques, and the line's ends and important nodes are marked.
The working principle of electrical control cabinet mainly includes the following aspects:
1.Power supply principle: An external power source, often AC or DC, powers the electrical control cabinet.
2.Power distribution system operation: The power distribution system's primary duty is to distribute the electrical energy that is provided to different electrical systems and equipment.
3.Control system operation: PLCs and DCS are typically used by control systems to automate the control of production processes and electrical equipment.
4.Signal processing: Electrical control cabinets typically have a number of input and output ports that are capable of receiving and processing both digital and analog electrical signals.
5.Protection function: These protective parts will act fast to cut off the power supply and stop more equipment damage as soon as abnormal situations like overcurrent and overvoltage are recognized. Additionally, it is possible to do real-time monitoring and abnormal alarm of device condition.
