Electrostatic grounding protection device for detecting grounding resistances

Abstract

The invention discloses an electrostatic grounding protection device for detecting grounding resistances, which belongs to the technical field of electrostatic-conductive grounding equipment, and mainly solves the problem that the existing electrostatic conductive grounding system can not perform periodical grounding resistance detection when in use so as to achieve the effect of reliably discharging electrostatics to the ground. The electrostatic grounding protection device disclosed by the invention is mainly characterized in that the device comprises a base and a cap, and the base and the cap constitute a closed cavity; the bottom in the cavity of the base is provided with an insulation board, electrostatic-conductive connecting plates and electrostatic-conductive grounding plates are arranged on the insulation board at certain intervals, and the electrostatic-conductive connecting plates and the electrostatic-conductive grounding plates respectively pass through the left side walland the right side wall of the base by inner holes of oilproof insulation sleeves; and a connecting copper plate enables the electrostatic-conductive connecting plates and electrostatic-conductive grounding plates which are spaced to be communicated by coupling screws. The electrostatic grounding protection device disclosed by the invention has the characteristics that the device is easy to detect and protect and difficult to rust in case of being placed in the open air, is mainly used as the electrostatic grounding protection devices on field large oil storage tanks, oil pipelines and gasoline pump stations, and provides reliable guarantee for reliably discharging the electrostatics of the large oil storage tanks, the oil pipelines and the gasoline pump stations to the ground.

Description

technical field [0001] The invention belongs to the technical field of static conduction grounding equipment. Specifically relates to an electrostatic grounding protection device for detecting grounding resistance on large-scale oil storage depots in the field, oil pipelines and gas pumping stations. Background technique [0002] The static electricity of large-scale oil storage depots, oil pipelines, and gas pumping stations in the field needs to be reliably released into the ground. The current method is to directly lead long static conductive plates from large oil storage depots in the field to connect with grounding bodies buried in the ground, so that static electricity can leak into the earth. In this way, the grounding resistance of the grounding body and the ground cannot be regularly detected during use, so that when the grounding resistance is too large, the static electricity cannot be reliably leaked into the ground through the grounding body. In this state, lar...
