What are the distribution equipment and electronic components of the low-voltage control cabinet?

Low-voltage control cabinet is one of the common components in modern control systems, used to control and protect various electrical equipment and electronic components, such as motors, lighting, heaters, etc.

The main distribution equipment and electronic components of the low-voltage control cabinet are described as follows:

1. Circuit Breaker

Circuit breaker is one of the common electrical components in the control cabinet. It is mainly used to cut off the circuit in time when the circuit is overloaded or short circuit to protect the safety of equipment and personnel. In the low-voltage control cabinet, the commonly used circuit breakers are air circuit breakers and leakage circuit breakers.

2. Contactor

Contactor is an electrical component of an open and close circuit, which can control the power supply in the circuit to realize the opening and closing of the device. The contactor in the low-voltage control cabinet is usually composed of a group of open-close contacts. When the power supply is connected, the contactor closes the circuit and the equipment starts to work.

3. Relay

A relay is an electrical component commonly used to control equipment such as temperature, humidity, airflow, lighting, etc. It is essentially a switch that controls the operation of a device by connecting or disconnecting different circuits.

4. Voltage, ammeter and oscilloscope

Voltage, ammeter and oscilloscope are instruments used to measure the voltage, current and other physical quantities in the circuit. The voltmeter and ammeter in the low-voltage control cabinet require high precision, and can display the current, voltage, power and other parameters of the system.

5. Fuse

A fuse is an electrical protection device, mainly used to protect electronic components and equipment from being burned by overcurrent. The fuse matches the corresponding capacity according to the rated current of its live circuit, once the circuit is overloaded, the current will exceed the capacity of the fuse, and the fuse will cut off the circuit, thus protecting the device from damage.

6. Computers and controllers

The computer and controller in the low-voltage control cabinet are the key devices used to manage and control all equipment and components. It is commonly used to monitor and control large systems, automated production lines and industrial robots.

7. Photoelectric sensor

Photoelectric sensor is a kind of electronic component that can convert photoelectric signal into electrical signal and control it. It can detect the motion state of the workpiece in real time by receiving the photoelectric signal of the base to ensure the safety and normal operation of the production line.

8. Transformer

A transformer is an electrical component that can convert voltage into different voltage levels. It is commonly used to control the supply circuit of high-voltage equipment and to transmit and distribute electrical energy.

9. Button switch

Push-button switch is a small electrical component used to control electrical equipment. It connects or disconnects the circuit by pressing the button switch. Push-button switches are often used to control lights, motors, conveyor belts, conveyors, sensors and other terminal equipment.

10. Cables

A cable is an electrical device used to transmit power or signals. The cables in the low-voltage control cabinet are used to transmit signals from the computer and sensors to the controller for intelligent control. At the same time, cables can also be used to connect additional external devices and control components.
