Distribution boxes and distribution cabinets can be said to be indispensable to all electricity-related things. Their existence brings convenience to the management of power supply, so their functions are still very large, but what are the differences in the uses of the two?
In terms of use, distribution boxes are generally used in households, while distribution cabinets are mostly used in centralized power supply, such as industrial electricity and building electricity, etc. Both distribution boxes and distribution cabinets belong to complete sets of equipment. The power box is a low-voltage complete set of equipment. The power distribution cabinet has high voltage and low power. The size of the power distribution box and the power distribution cabinet are also different. Of course, the bigger one is the power distribution cabinet. In terms of form, the distribution cabinet is a vertical cabinet as its name suggests, while the distribution box is a box type, and the box that distributes electrical energy is called a distribution box. It is mainly used for the control and distribution of electrical equipment, and protects 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 power distribution cabinet is a low-voltage power distribution device that assembles switchgear, measuring instruments, protective appliances and auxiliary equipment in a closed or semi-closed metal cabinet or on the screen according to the electrical wiring requirements. During normal operation, the circuit can be switched on or off by means of manual or automatic switches. There are many types of power distribution cabinets. When it fails or does not operate normally, it will cut off the circuit or alarm with the help of protective appliances. By means of measuring instruments, various parameters in operation can be displayed, and some electrical parameters can also be adjusted to prompt or send signals for deviations from the normal working state.
The power distribution cabinet can be equipped with various explosion-proof electrical appliances or a combination of various explosion-proof electrical appliances, such as: explosion-proof power (lighting) distribution box, explosion-proof electromagnetic starter, explosion-proof power maintenance box, etc.; and the distribution box can be equipped with circuit breakers, contactors, Components such as thermal relays, buttons and indicator lights can be used for lighting and power motor control purposes. Then it means that the power distribution cabinet can contain the power distribution box, and the functions are more extensive and diversified. Commonly used in various power generation, distribution, substation factories, etc.
