Power Distribution Box It is a huge number of parameters on the data, generally constituting the low-voltage forest according to the electrical wiring. It is required to assemble switchgear, measuring instruments, protective appliances and auxiliary equipment in enclosed or semi enclosed metal cabinets or panels to form low-voltage distribution boxes. During normal operation, the circuit can be turned on or off with the help of manual or automatic switches. The construction power distribution system shall be equipped with a general distribution box, a sub distribution box, and a switch box, which shall be set in a hierarchical manner in the order of "general opening opening", and form a "three-level distribution" mode.
The distribution box has the advantages of small size, simple installation, special technical performance, fixed location, unique configuration function, not limited by the site, relatively common application, stable and reliable operation. The distribution box should be installed in the center of the electric equipment or relatively concentrated load as far as possible to ensure that the three-phase load is balanced. The switch box shall be installed as close as possible to the electric equipment controlled by it according to the site conditions and working conditions. High space utilization rate, less land occupation and environmental protection effect.
The distribution box is composed of switchgear, measuring instruments, protective appliances and auxiliary equipment assembled in enclosed or semi enclosed metal cabinets or screens according to the electrical wiring requirements to form a low-voltage distribution box. During normal operation, the circuit can be turned on or off with the help of manual or automatic switches. Cut off the circuit or give an alarm with the help of protective appliances in case of failure or abnormal operation. Various parameters in operation can be displayed by measuring instruments, and some electrical parameters can be adjusted to prompt or send signals for deviation from the normal working state.
