Home distribution box working principle

The distribution box is composed of switchgear, measuring instruments, protective electrical appliances and auxiliary equipment assembled in closed or semi-enclosed metal cabinets or screen panels according to the electrical wiring requirements to form a low-voltage power distribution device. During normal operation, the circuit can be switched on or off by means of a manual or automatic switch. In the event of malfunction or abnormal operation, the circuit or alarm is cut off by means of a protective appliance. Measurement instruments can be used to display various parameters in operation, and certain electrical parameters can be adjusted to indicate or signal deviations from normal operating conditions. Commonly used in all hair, distribution, substations.

Household distribution box <br> <br> manageable use, when a circuit fault occurs conducive to repair. Distribution boxes and switchboards, distribution boards, and other distribution equipment are centralized devices for the installation of switches and meters.

The commonly used distribution box is made of wood and iron plate. Now the electricity consumption is quite large, so it is still more used for iron.

The purpose of the distribution box: Of course, it is convenient to stop, send electricity, play the role of measurement and judgment stop, power transmission.

The working principle and usage of the explosion-proof distribution box and the household distribution box are the same. However, the use of explosion-proof distribution box special venues, China's coal industry, PetroChina, Sinopec, CNOOC, electricity, metallurgy, railways, steel, ships, *, aerospace, * fire, chemical, government departments, venues, transportation. Gas station paint room grain and oil equipment CNC lathe dust workshop Petrochemical plant petrochemical plant, oil platform, oil pump room, transfer station Petrochemical industry: chemical pharmaceutical coal mine, power plant refinery paint factory, distribution room, plant, water pump side, belt corridor, trestle, Boiler Room……

Explosion-proof distribution box safety operating procedures are very strict and must be strictly enforced

1. It is strictly forbidden for non-electricians to disassemble and repair the electrical equipment in the distribution box.

2. No debris shall be piled up around the distribution box. Is the metal fence complete? Is the crimping of the protective ground wire of the metal fence firm?

3. The electrician checks the distribution box at least twice daily.

4. Check if the contacts of the switch and fuse are overheated and whether the wiring insulation is damaged.

5. Check whether the electrical components in the distribution box are intact and whether the meter indication is within the specified range.

6. Check the electrical system diagram in the distribution box and the name of the circuit in each switch.

7. Deactivated equipment and power circuit must be powered off and locked.

8. Under normal circumstances, clean the distribution box weekly and remove dust twice.
