1. Conceptual distinction
1. Distribution box
The distribution box is a small power distribution box that contains power switches and safety devices. The structure is relatively simple, and is mostly used for terminal power distribution. The distribution box is the last level of power distribution facilities in the power supply system. A distribution box can be a power inlet and multiple power supply output circuits. The power supply output circuit is drawn from the distribution box to each electrical load. The size of the distribution box is small and cannot be put into large-scale power distribution equipment, so the capacity of the distribution box is not large. Generally, a distribution box is used for 4-8 small loads. The distribution box is arranged in the center of the power supply load, using cables or The wires carry electricity to the load.
2. Power distribution cabinet
The power distribution cabinet is the upper-level power distribution equipment of the power distribution box. It is large in size and can contain larger electrical equipment. Therefore, it is generally used as a medium-capacity load power distribution equipment, including power distribution boxes, motors, etc. Its applicable capacity is different in each process field, generally from several kilowatts to dozens of kilowatts. In addition to the leakage protection and short circuit protection provided by the traditional distribution box, it also provides overvoltage protection, ignition and power failure, lightning protection, automatic power supply, temperature protection, power limit, fault record, self-check function, learning memory, mobile internet Functions such as visualization and digitization.
2. Functional distinction
Simply put, the box for distributing electric energy is called a distribution box. The distribution box is mainly used to control and distribute electrical equipment, and to protect the line from overload, short circuit and leakage. Distribution boxes are installed in various places, such as schools, institutions, hospitals, factories, workshops, homes, etc., such as lighting distribution boxes, power distribution boxes, etc. The distribution box is small in size and can be hidden in the wall or stand on the ground.
