Background

The distribution network is an electric power network which receives electric energy from a transmission network or a regional power plant and distributes the electric energy to various users on site through distribution facilities or step by step according to voltage. The power distribution network consists of overhead lines, cables, towers, distribution transformers, isolating switches, reactive power compensators, accessory facilities and the like, and plays a role in distributing electric energy in a power network. In power distribution networks, the use of power distribution cabinets is particularly common. The distribution cabinet is a final-stage device of a distribution system. The power distribution cabinet is a general name of a motor control center. The power distribution cabinet is used in the occasions with dispersed loads and less loops; the motor control center is used for occasions with concentrated loads and more loops. They distribute the power of a certain circuit of the upper-level distribution equipment to the nearby loads. This level of equipment should provide protection, monitoring and control of the load.

The existing power distribution network has the following problems: (1) whether the existing distribution network can meet the requirement of load development; (2) how well the insulation ages; (3) whether the wire diameter of the wire is too thin or not, and whether a bottleneck line exists or not; (4) the reliable index of each line power supply is high and low; (5) the number of switches in the line, the switching time and which faults occur in operation; (6) the line loss rate index is high and low; (7) line repair conditions.
