Core information of Industrial electrical cabinet

Access control cabinets are a combination of one or more low-voltage switchgear, as well as control, measurement, signal, protection, regulation and other equipment that are matched with them. All electrical and mechanical connections inside are completed by the manufacturer and assembled by structural components. As an important component of the power system, the core functions of the Electrical distribution cabinet include energy distribution and conversion, motor control, and reactive power compensation. It can effectively protect personal safety, prevent direct and indirect electric shock risks, and protect equipment from external environmental influences, ensuring stable and safe operation of the power system.

The design, production, and use of Fiber optic cabinet outdoor must strictly follow three core standards to ensure equipment compliance and operational safety. These three standards are GB7251.1 "Low Voltage Switchgear and Control Equipment" Part 1 (Type Test and Partial Type Test Equipment), IEC60439.1 "Low Voltage Switchgear and Control Equipment" Part 1 (Type Test and Partial Type Test Equipment), and GB/T 15576-2008 "Low Voltage Reactive Power Compensation Equipment". Together, they form the standard system for low-voltage distribution cabinets, providing a standardized basis for equipment production and application.

Divided by purpose, Cabinet power distribution is mainly divided into three categories, each responsible for different distribution and control tasks. One is the power supply cabinet (PC: Power Center) used for power distribution, whose core function is to receive electrical energy and distribute it, adapting to various power transmission scenarios; The second is the Motor Control Center (MCC) used for motor control, which is specifically designed for controlling operations such as starting, stopping, and speed regulation of motors; The third is the reactive power compensation cabinet (also known as the capacitor cabinet) used for compensation, which is mainly used to compensate for reactive power in the power system and improve the efficiency of energy utilization.

The external wire slots should consider factors such as spare cores and shielding layers in the incoming wires on site, and larger specifications should be selected; Switches and fiber optic boxes are generally arranged below the Electrical system cabinet, and the reserved wiring space needs to fully consider the bending radius of the network cables and fibers. Lighting fixtures should be installed on the top of the cabinet, controlled by door control switches. One set should be installed on a single-sided layout, and two sets should be installed on both sides.

The basic structure of a low-voltage Distribution board cabinet is centered around compartment division, which aims to protect personal and equipment safety. The cabinet is usually independently divided into four compartments, namely the busbar compartment (including horizontal and vertical busbar compartments), functional unit compartment (also known as switch compartment), cable outlet compartment (including cable compartment), and secondary equipment compartment. Each compartment has clear division of labor and does not interfere with each other.

Its main components include cabinets, busbars, and functional units. Exterior distribution cabinets serve as the shell skeleton, responsible for the installation and support of internal equipment; Bus is a low impedance conductor that can connect multiple circuits and is the core carrier of electrical energy transmission; A functional unit is a combination of all electrical equipment and mechanical components that perform the same function, including incoming and outgoing units, to ensure the normal operation of the equipment.
