How to calculate the temperature rise test temperature of power fittings: understand the heating condition of each part of the generator during operation, and check whether the measured data meet the technical conditions or relevant standards of the manuf

The insulation strength of power fittings can withstand the working voltage for a long time, and when overvoltage occurs in the system of this voltage level, the appliance can make the operator's body complete, which is called basic insulation appliance.

The total content of impurities (except iron, tin, aluminum and nickel) in hot-dip galvanizing liquid used for power fittings should not exceed 1.50% of the total mass. Refer to GB / t470 for impurities.

According to function and structure, power fittings can be divided into suspension clamp, tension clamp, ut clamp, connecting fittings, connecting fittings, protective fittings, equipment clamps, T-type clamps, bus fittings, stay wire fittings, etc.

The insulation resistance of power fittings will decrease with the increase of temperature, because too high temperature will aggravate the dielectricization of resistance, and then lead to the increase of conductivity and the decrease of resistance. Mois
