On-line measurement method for surface charge surge of basin-type insulator based on Kelvin electrostatic probe

The invention discloses a basin-type insulator surface charge surge on-line measurement method based on a Kelvin electrostatic probe, and the method comprises the following steps: setting the Kelvin electrostatic probe, enabling the Kelvin electrostatic probe to face a pouring opening of the basin-type insulator, wherein the Kelvin electrostatic probe is separated from the basin-type insulator; and detecting the variation and the change rate of the surface potential of the basin-type insulator at the pouring gate through the Kelvin electrostatic probe to deduce the surface charge change condition of the basin-type insulator. According to the basin-type insulator surface charge surge on-line measurement method based on the Kelvin electrostatic probe, non-contact on-line measurement can be achieved, the original structure of the basin-type insulator does not need to be changed, and the basin-type insulator surface charge surge on-line measurement method has the advantages of being high in accuracy, low in cost
