Analysis of the role of distribution box and its advantages

At present, the distribution box is a cabinet that integrates electrical components for power distribution. The function of the power distribution box is to distribute and control the electrical equipment. When the circuit is overloaded, short-circuited and leaked, the distribution cabinet can also provide power-off protection. Each unit in most communities will be equipped with a dedicated distribution box. So, what are the functions and advantages of the distribution box?

The role of the distribution box

The electrical distribution box is the total circuit distribution box for all users of electricity, and the distribution cabinet, switchboard, etc.,it is a complete set of equipment for centralized installation of switches, meters and other equipment.

The power distro box distributes electric energy reasonably, which is convenient for opening and closing the circuit. It has a high level of safety protection and can visually display the conduction state of the circuit. It is easy to manage and facilitates maintenance when a circuit failure occurs. Therefore, the use of power distribution boxes and power distribution cabinets is convenient for management, facilitates maintenance when a circuit failure occurs, also facilitates the shutdown and transmission of power, and plays a role in measuring and judging the shutdown and transmission of power. At present, the most commonly used distribution boxes on the market are made of wood and iron plates, and most of them are iron distribution boxes.

Application fields of different types of distribution boxes

1. Fixed panel switch cabinet, often called switch board or power distribution panel. It is an open-type switch cabinet with a panel covering. The front is protected, and the rest can touch the live parts. The protection level is low. It can only be used in industrial and mining enterprises that require low power supply continuity and reliability.

2. Protective switchgear refers to a low-voltage switchgear in which all sides except the installation surface are enclosed. All electrical components of this cabinet are installed in a closed enclosure made of steel or insulating materials. In addition, there are protective bench-type switch cabinets, which are equipped with control, measurement, signal and other electrical appliances on the panel. Mainly used as a power distribution device at the craft site.

3. Drawer switch cabinet. The closed shell is made of steel plate, and the electrical components of the incoming and outgoing circuits are all installed in the withdrawable drawer to form a functional unit that can complete a certain type of power supply task. There are also isolation measures between each functional unit. It is a relatively advanced switchgear with the characteristics of reliability, safety and interchangeability. It is suitable for industrial and mining enterprises and high-rise buildings that require high power supply reliability as a centralized control power distribution center.
