The role of distribution box in the power supply system. The distribution box has the characteristics of small volume, simple installation, special technical performance, fixed location, unique configuration function, no site restriction, common application, stable and reliable operation, high space utilization, small land occupation and environmental protection effect. The distribution box is the control center for commanding various components in the power supply line to reasonably distribute electric energy, It is the control link to reliably accept the upper power supply and correctly feed out the load electric energy, and it is also the key to obtain the user's satisfaction with the power supply quality (improving the operation reliability of the power distribution box is the goal of creating a high-quality project. It is an electric power supply system project. According to the technical standards and requirements of the high-quality project, the construction cycle must be accelerated, and the target control must be carried out from the divisional project

 

1. The door of the distribution box shall be equipped with a lock and shall be held by a specially assigned person.

 

2. When the regular maintenance and inspection of the distribution box are stopped, the corresponding electric Tan disconnector at the previous level must be opened and powered off, and the power-off sign of "stop switching on and someone working" shall be hung. Live work is strictly prohibited.

 

3. The distribution box shall have title, use, shunt sign and system wiring diagram.

 

4. The distribution box shall be inspected and maintained regularly. The inspection and maintenance personnel must be professional electricians.

 

5. During the inspection and maintenance of the distribution box, insulating gloves and shoes must be worn as required, and the insulating tools provided by the electrician must be used. The maintenance and inspection shall be recorded+

 

It is also inseparable from the control and management of the distribution box (the distribution system should be equipped with distribution cabinet or general distribution box, branch distribution box and switch box, and implement three-level distribution (the role and operation quality of the distribution box in the power supply system are becoming more and more stable, and the power supply reliability is continuously improved to meet the needs of production and life for power supply quality (although the application of power distribution box has been very common, there are some problems in construction and operation, which more or less lead to some faults, resulting in certain economic losses and social impact. (for this, according to the different characteristics of distribution box faults in power supply lines
