Background technique

Distribution Network (Distribution Network) refers to the power network that connects and receives power from the transmission network (or local power plants), and supplies and distributes electric energy to various users on the spot or step by step. According to the difference, it can be divided into high-voltage distribution network, medium-voltage distribution network and low-voltage distribution network. The voltage level of the low-voltage distribution network is 0.38kV and 0.22kV, and the distribution transformer of the medium-voltage distribution network is used as the power supply, and the electric energy is directly sent to the user through the low-voltage distribution line; the low-voltage distribution network goes deep into the city center and densely populated areas Compared with the high-voltage and medium-voltage transmission network, the low-voltage distribution network has a short transmission distance, large power supply capacity, and higher reliability requirements. With the continuous improvement of the country's requirements for the power supply capacity and power supply quality of low-voltage distribution networks, higher requirements are put forward for the professionalism of low-voltage line fault repair and the time for power supply restoration. Currently, it is common in high-rise buildings, urban residential areas, and industrial users. The cluster busbar (that is, the plug-in busbar) is used for power supply. Usually, a section of busbar is installed on one floor, and some areas also use full-cable mode for power supply.
