The small power distribution box manufacturer will show you that the small power distribution box has the advantages of small size, simple installation, special technical performance and fixed location. Its configuration function is unique, it is not limited by the site, and its application is relatively common, and its operation is stable and reliable, the space utilization rate is high, it occupies less land, and it also has environmental protection effects. It is a control center used to command various components in the power supply line to distribute power reasonably. It is a control link that can reliably accept the upper power supply and correctly feed out the load power. It is also a key to obtain users' satisfaction with the power supply quality. Purpose of the small power distribution box: it can reasonably distribute electric energy and facilitate the opening and closing of the circuit. It has a high level of safety protection and can visually display the conduction state of the circuit; The working principle of the small power distribution box is to assemble the switchgear, measuring instruments, protective appliances and auxiliary equipment in a closed or semi closed metal cabinet (or on the screen) according to the requirements of electrical wiring to form a low-voltage small power distribution box. During normal operation, the circuit can be switched on or off with the help of manual or automatic switch. Cut off the circuit or give an alarm with the help of protective appliances in case of failure or abnormal operation. With the help of measuring instruments, various parameters in operation can also be displayed, some electrical parameters can be adjusted, and prompts or signals will be given when deviating from the normal working state.
