The invention discloses a lightning arrester independent grounding body convenient to construct. Supporting rods are arranged on the upper top surface of a stabilizing disc, and a sliding contact is arranged at the top of each supporting rod; the lightning arrester independent grounding body is characterized in that when the stabilizing disc is placed at the bottom of an electric pole, the slidingcontacts on the top of the supporting rods can enter circular holes in the bottom of the electric pole; and after the sliding contacts on the top of the supporting rods enter the corresponding circular holes in the bottom of the electric pole, the sliding contacts can press and contact the inner walls of the circular holes in the bottom of the electric pole forcefully; a main ground electrode isarranged in the middle of the bottom surface of the stabilizing disc, and auxiliary ground electrodes are arranged on the exterior of the main ground electrode; and the lightning arrester independentgrounding body is characterized in that after the electric pole is completely erected, the main ground electrode in the middle of the bottom surface of the stabilizing disc and the additional ground electrodes can be densely and firmly inserted into the soil at the bottom of the electric pole.
Description
technical field [0001] The invention relates to electrical protection grounding, directly relates to a single grounding body of a lightning arrester which is convenient for construction, and is especially suitable for use in lightning protection grounding of a 10KV lightning arrester. Background technique [0002] In the classification of electrical protective grounding, it is generally divided into anti-shock grounding, lightning protection grounding, and anti-static grounding. The anti-shock grounding is to prevent the insulation damage of electrical equipment or leakage current, so that the exposed conductive parts that are usually not charged will be charged and cause electric shocks, and the exposed conductive parts of the equipment are grounded, which is called anti-shock grounding. Lightning protection grounding is to conduct lightning to the earth to prevent lightning current from causing electric shock to people or damage to property. Anti-static grounding is to in...
