  • The differences between the meter box and the distribution box

     Different advantages1. Electric meter box is a special box for electricity metering, which completely solve the personal injury and death accidents caused by poor grounding of the box and overlapping of foreign matters; low comprehensive use cost; effectively resist the impact of external forces; no suffocation gas will be produced when burning under high temperature.2. Distribution box: small size, simple installation, special technical performance, fixed location, unique configuration function, not limited by the site, relatively common application, stable and reliable operation, high space utilization, less land occupation and environmental protection effect.Different uses1. Meter box: the meter box is a special box for low-voltage power distribution lines, generally used as the cable branch box, low-voltage distribution box, water pump control box, communication device cabinet, street light and traffic light control box, multi-functional metering box, integrated distribution box, capacitance compensation box, terminal box, wall mounted distribution box, metering box, etc. in the public power grid.2. Distribution box: the distribution box is generally used for household use, or for centralized power supply, such as industrial power and building power. The distribution box belongs to low-voltage complete equipment.

  • Simple knowledge about circuit breakers

    Circuit breaker refers to the switch device that can  turn on, carry and turn off the current under abnormal circuit conditions within a specified time. The circuit breaker can be used to distribute electric energy, start asynchronous motor infrequently, and protect power lines and motors. When they have serious overload, short circuit, undervoltage and other faults, it can cut off the circuit automatically. Its function is equivalent to the combination of fuse switch and over / under heat relay. It is not necessary to change the parts after breaking the fault current. At present, BACO circuit breaker has been widely used. The circuit breaker is divided into high-voltage circuit breaker and low-voltage circuit breaker according to its scope of use. The demarcation of high-voltage and low-voltage boundary is relatively vague. Generally speaking, the circuit breaker above 3KV is called high-voltage apparatus.
