The dynamic load management system of distribution line is used to solve the problems such as limited load capacity of distribution line and difficult to meet the demand of load growth, and to improve the operation level and load capacity of the line without changing the existing network structure and without affecting the thermal stability of the line.

With the development of the national economy, the contradiction between the power supply capacity and the actual power demand in some areas is becoming more and more obvious, facing the problems of line channel blockage and limited substation transmission capacity during the peak of power consumption such as the peak summer; when the N-1 and N-2 operation mode occurs in some areas, it will directly affect the load transmission, and even endanger the stable operation of the power grid and the safety of power transmission and transformation equipment.

The distribution transformer load intelligent monitoring and anti-burning early warning management system is suitable for the operation monitoring of distribution transformers. Through real-time monitoring of the distribution transformer operating parameters and the ambient temperature, the hot spot temperature of the distribution transformer winding under the current operating conditions is calculated, and the temperature rise classification early warning information is provided to prevent the distribution transformer from burning out and provide guarantee for the safe and reliable operation of the distribution transformer.

Affected by natural and man-made factors, the contact resistance of some key wire clamps (strain clamp, wire connection tube, etc.) of transmission lines is too large, and there is a risk of overheating when encountering heavy load, and its temperature may exceed the safety limit. At this time, the wire clamp not only has the risk of burning loss, but also its mechanical strength will decrease, which seriously affects the safety of line operation.

The operating environment of power cables includes a variety of complex occasions, including direct burial, pipe penetration and cable trenches, which are particularly difficult for operation and maintenance personnel to access. Once a power cable breakdown occurs at these locations, the point of failure cannot be quickly identified.
