A grounding device for electrical engineering

Abstract

The invention discloses an electrical engineering grounding device, and mainly relates to the field of electrical engineering. The device includes an insulating base plate, a protective sleeve is arranged in the middle of the insulating bottom plate; a length-adjustable conductive screw rod is arranged in the protective sleeve; a grounding electrode is vertically welded at the bottom of the conductive screw rod; an annular bracket is arranged on the upper side of the insulating base plate; a first conductive sleeve, a conductive connecting block and a second conductive sleeve are sequentiallyarranged at the top of the annular bracket from bottom to top; a plurality of threaded connecting holes are formed in the outer wall of the conductive connecting block, an insulating protective coveris arranged at the top of the insulating bottom plate, a junction box is arranged on the outer side of the insulating protective cover, a line bank is arranged in the junction box, a wire is arrangedat one end of the line bank, and the end, away from the line bank, of the wire extends out of the junction box. The device has the beneficial effects of rust prevention, long service life, small damage to the indoor floor, convenience in capacity expansion and convenience in use.

Description

technical field [0001] The invention relates to the field of electrical engineering, in particular to an electrical engineering grounding device. Background technique [0002] In order to improve the safety of electrical equipment, it is necessary to ground the electrical equipment. Most of the existing grounding devices use a metal rod as the ground electrode. After the ground electrode is driven into the ground vertically, the flat steel is buried as a horizontal connection line Then weld the flat steel and the ground electrode together, and then connect the electrical equipment and the flat steel through wires, and when burying the flat steel, it is necessary to destroy the ground, especially when multiple electrical equipment is installed indoors, multiple flat steel may be buried , and all need to destroy ground when laying flat steel every time, very inconvenient, and ground electrode is very prone to rust at the boundary between ground and air, affects the service lif...
