Embodiment 1
[0029] An embodiment 1 of the present invention is used for real-time detection of heating conditions of fittings joints of overhead lines. First of all, it is necessary to obtain the environmental meteorological parameters and the basic parameters of the line as the input of the calculation. Considering the need to ensure the consistency of environmental factors, this embodiment selects an operating line with 1 to 2 tension fittings within 1 km for implementation, and does not explicitly limit the scope of the operating voltage level. When the three-phase current is unbalanced, the zero-sequence current limit is generally set to 10% In (In is the rated current of the line).
[0030] The calculation method of the wire temperature involves the determination of various environmental parameters, including the radiation heat dissipation coefficient, the heat absorption coefficient of the wire surface, the wind speed perpendicular to the wire, the sunlight intensity, and the ambien...
