Basic knowledge of Electrical Control Cabinet
What is an Electrical Control Cabinet?
The Electrical Control Cabinet is a cabinet that integrates a variety of electrical components and equipment, and realizes the electrical control and monitoring of industrial equipment through the control components such as buttons, indicators and switches on the panel. It is not only responsible for centralized control of the switch, start and stop of the equipment, but also can adjust and monitor the parameters of the equipment to ensure the normal operation of the equipment.
The role of the Electrical Control Cabinet rear panel
The backplane is a metal plate installed in the housing that provides structural support for rail mounting and wiring pipes. Metal rails have standardized dimensions and provide mounting structures for electrical equipment. Wiring pipes organize wiring while also helping to control electromagnetic interference between devices in the box.
What electrical components are contained in the Electrical Control Cabinet
There are eight types of electrical components within the Electrical Control Cabinet that define and organize several different functions performed by the panel. These components include:
1.Main circuit breaker
In most industrial applications, the main circuit breaker can handle voltages between 120V and 480V.
2.Lightning arrester
This component prevents lightning strikes or mains surges from damaging electrical components in the panel due to overvoltage.
3.Transformer
Depending on the input voltage, the transformer can reduce the voltage of various components to 120V, or to 24V if the input power is 120V.
4.Terminal
These blocks help organize and distribute wire arrays from different sources to different electrical devices.
5.Programmable Logic Controller (PLC)
This is essentially a CPU contained within the control panel. This unit is the brain of the control panel, providing monitoring and control of various mechanical processes. Various inputs and outputs of the mechanized functions of the production equipment will be included.
6.Relays and contactors
These on/off switches control the mechanized functions according to commands from the PLC. Smaller relays control functions such as lights and fans. Larger relays, called contacts, control more advanced functions, such as motors.
7.Network switch
The communication hub and network switch of the control panel facilitate the communication between the PLC and various network compatible devices on the production line.
8.Human Machine Interface (HMI)
These components allow the operator to monitor or control certain functions of the machine. Common ones include video monitors, joysticks, buttons, switches, and keyboards.
Precautions for later maintenance of Electrical Control Cabinet
1.Clearly marked components, wiring, and terminals
2.Ability to monitor the status of various electrical connections
3.Control particles and dust inside the enclosure
4.Pest control measures
5.Internal components of the Electrical Control Cabinet should be replaced regularly
Electrical Control Cabinets are mainly used in industries
Electrical control cabinets are mainly used in food and beverage, oil and gas, medical, generator power circuits, manufacturing, construction, water treatment, material handling and other industries.
