Analysis Of The Main Capacitance And Voltage Distribution Mechanism Of Epoxy Resin Insulators

When high voltage epoxy is used as a unit in a series structure, its main capacitance increases in proportion due to its parallel or series interaction with surrounding stray capacitances, thus making the voltage distribution across each epoxy resin insulator more balanced.

The voltage distribution along the high voltage epoxy resin series is more uniform because the increased main capacitance reduces the disturbance of external stray capacitances on the voltage distribution, thereby smoothing the voltage gradient of each high voltage standoff plate from the conductor end to the ground end. Furthermore, by controlling the capacitor shielding or capacitor equalization screen arrangement between the high voltage standoff insulators inner core rod, outer casing, and hardware (such as the built-in capacitor equalization screen scheme described in a certain patent), the main capacitance can be directly enhanced and the uniformity of the series voltage distribution can be improved.
