Abstract

The invention discloses a pendulum type grounding rod design method for eliminating space electric field measurement accumulated charges. The method comprises the steps of enabling an insulating rod to be perpendicular to the ground, enabling a first end of the insulating rod to be grounded, and enabling a second end of the insulating rod to support a field mill; grounding the fixed end of a metalrod, and enabling the metal rod to swing within the range of 0 to 90 degrees relative to the ground; when the metal rod forms an angle of 90 degrees with the ground, the movable end of the metal rodbeing in contact with the field mill; the length of the metal rod being the same as that of the insulating rod; setting the swinging time of the metal rod according to the sampling interval of the field mill, and swinging the metal rod to the ground after the electric charge of the field mill is fully discharged when the metal rod is in contact with the field mill.

Description

technical field [0001] The invention relates to the technical field of electromagnetic measurement, and more particularly, to a method and system for designing a pendulum-type grounding rod for eliminating accumulated charges in space electric field measurements. Background technique [0002] The existing DC electric field measurement devices are all field mill sensors to measure the DC electric field near the ground. The working principle is a rotating voltmeter. Sense current, convert current to voltage, amplify, rectify, filter and adjust, and output a DC voltage. This DC voltage represents the value of the DC electric field near the surface of its rotating blade. Calibration through the DC electric field calibration device can be converted into the electric field value under the actual line. [0003] If the field mill type field strength meter with this working principle is used to measure the space electric field, there will be a problem of floating grounding, that is...
