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 as follows:
Circuit breaker is one of the common electrical components in the control cabinet. Mainly used to timely cut off the circuit in case of overload or short circuit, protecting the safety of equipment and personnel. In low-voltage control cabinets, commonly used circuit breakers include air circuit breakers and leakage circuit breakers.
A contactor is an electrical component that opens and closes a circuit, which can control the power supply in the circuit and achieve the opening and closing of the equipment. The contactors in the low-voltage control cabinet are usually composed of a set of open close contacts. When the power is connected, the contactors close the circuit and the equipment starts working.
A relay is an electrical component commonly used to control equipment such as temperature, humidity, airflow, and lighting. It is essentially a switch that controls the operation of equipment by connecting or disconnecting different circuits.
Voltage, ammeter, and oscilloscope
Voltage, ammeter, and oscilloscope are instruments and equipment used to measure physical quantities such as voltage and current in a circuit. The voltage and current meters in the low-voltage control cabinet require high accuracy and can display parameters such as current, voltage, and power of the system.
A fuse is an electrical protection device mainly used to protect electronic components and equipment from being burnt out by overcurrent. The fuse matches the corresponding capacity based on 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 to protect the equipment from damage.
Computers and controllers
The computer and controller in the low-voltage control cabinet are key equipment used to manage and control all equipment and components. It is typically used for monitoring and controlling large systems, automated production lines, and industrial robots.
