Distribution box, also known as low-voltage distribution box, is a closed or semi-closed metal or wooden box that assembles components such as switches, measuring instruments, protective appliances and auxiliary equipment of specified standards in a closed or semi-closed metal or wooden box according to the design requirements. The integrated box is called distribution box.
Features of distribution box:
1. The distribution box is the part of the original circuit control, which is integrated according to certain standards. It is small in size, easy to install, not restricted by the site, and convenient for inspection and control.
2. It is convenient for standardization and customization, with high safety. It can intuitively display the conduction state of the circuit, and the safety is guaranteed.
3. Economical and practical, the electrical components are all in the metal box, which plays a good protective role and prolongs the service life of the electrical components.
Distribution box classification:
1. Fixed panel switchgear, usually called switch panel or power distribution panel. It is a switch cabinet with only the panel part with shielding protection, and the protection level is lower.
2. Protective switchgear refers to a closed switchgear, except for the control surface and the switch board, the other box surfaces are closed.
Third, the drawer switch cabinet. This kind of switch cabinet is made of steel plate into a closed shell, and a drawer box that can be drawn out for installing electrical components is arranged in it, forming a unit that can independently realize a certain control function. Drawer-type switchgear has relatively small components and flexible control, and is often used as a centralized control system in power distribution centers.
Fourth, power, lighting distribution control box. Most of them are closed vertical installations, which are used more in the transformation of rural power grids.
The main function of the household distribution box The role of the household distribution box is to cut off and connect the power supply, effectively control each power line, and achieve the purpose of safe electricity use. Household use is an indoor control distribution box, and its structure is generally composed of leakage switch equipment and metering equipment.
