Distribution boxes and meter boxes play different roles in the power system, and their differences are mainly reflected in the following aspects:
1, Definition and purpose
Electric meter box
Definition: An electric meter box is a protective device specifically designed for installing energy measuring instruments.
Purpose: Mainly used to protect energy measuring instruments (such as ammeters, kilowatt hour meters, power meters, etc.) and circuits, preventing unstable operation of energy measuring instruments or safety hazards caused by external factors. The electric meter box can also monitor electrical energy, measure the amount of electricity, and play a role in power distribution. It is usually installed at the inlet and outlet of the power system and is one of the important safety devices in the power system.
Power Distribution Box
Definition: Distribution box is a specialized box used for low-voltage power distribution lines.
Purpose: Mainly used to distribute electrical energy to various rooms or electrical equipment. It includes components such as circuit breakers, sockets, etc. to protect the circuit and provide convenient power access points. Distribution boxes are widely used in various occasions such as residential areas, small shops, offices, and industrial plants.
2, Structure and Characteristics
Electric meter box
Structure: The electric meter box is usually composed of an electric meter, screws, wires, terminal blocks, grounding wires, and power switches. It is mainly divided into three parts: the meter box, the cover, and the back panel.
Features: The meter box is designed with overload prevention function, mainly controlling the flow of electrical energy through load switches. In addition, the electric meter box also has the characteristics of resisting external impact and not producing suffocating gas during combustion at high temperatures, which can solve personal injury accidents caused by poor grounding of the box and foreign object overlap.
Power Distribution Box
Structure: The internal component layout of the distribution box is relatively simple, but it contains various electrical components such as circuit breakers, fuses, wiring terminals, etc.
Features: The distribution box has a small volume, easy installation, special technical performance, and fixed position. Its configuration function is not limited by the venue and is widely used. At the same time, the operation of the distribution box is stable and reliable, with high space utilization and small footprint, and has environmental protection effects.
3, Application scenarios and capacity
Electric meter box
Application scenarios: The electric meter box is generally used as a cable branch box, low-voltage distribution box, water pump control box, communication device cabinet, street light and traffic light control box in the public power grid. It can also be used as a multifunctional measuring box, comprehensive distribution box, capacitor compensation box, terminal box, wall mounted distribution box, and measuring box.
Capacity: The capacity of the meter box is usually determined based on the specifications and quantity of the energy measuring instruments.
Power Distribution Box
Application scenarios: Distribution boxes are generally used for household use and are also used in centralized power supply, such as industrial and building electricity. It is a type of low-voltage complete equipment.
Capacity: The capacity of the distribution box is determined based on the electricity demand and can include multiple circuits and branch circuits to meet the electricity needs of different equipment and rooms.
In summary, there are significant differences between distribution boxes and meter boxes in terms of definition, purpose, structure and characteristics, as well as application scenarios and capacities. In practical applications, appropriate equipment should be selected according to specific needs to ensure the safe and reliable operation of the power system.
