In the paper the temperature field distribution in a urban distribution substation in Chongqing was calculated firstly. According to the parameters of the distribution substation and apparatuses in it, equivalent model was setup and method to calculate the boundary conditions for the temperature field is presented. Then factors influencing the distribution of temperature field in the distribution...
Nowadays, the methods of UHV system discharge detection are often by infrared imaging system, UV-C imaging system, etc. But none of them can measure the discharge degree of electric equipment quantitatively. As to the high dielectric level of the UHV system, the long distance from ground exists; especially in detecting the discharge of the electrical equipments on the UHV line tower, the detector...
