Problems solved by technology

[0008] Therefore, only one of the ground rod and the auxiliary electrode abuts on the high-voltage box while the other one does not abut on the high-voltage box due to interference of obstacles or the like.
Therefore, for example, when the ground rod is in contact with the high-voltage box but the auxiliary electrode is not in contact with the high-voltage box, the indicator light will go off regardless of whether the high-voltage box is grounded by the ground rod, and there is a problem that it is impossible to confirm that the high-voltage box is grounded by the ground rod.

Embodiment Construction

[0032] figure 1 It is a schematic configuration diagram showing a grounding wire as an example of the grounding device of the present invention. figure 2 yes figure 1 Magnified view of the mounting side clamp for the ground wire shown. image 3 yes figure 1 A zoomed-in view of the ground-side clamp for the ground wire shown.

[0033] Such as figure 1 As shown, the grounding wire 1 is a cable for grounding a metal container C for storing volatile organic solvents, etc., and one end (one end; the same below) is connected to a grounding object. In the container C of the example, the other end (the other end; the same below) is connected to a ground potential member E such as an iron post.

[0034] The ground wire 1 includes a mounting-side jig 2 as an example of a mounting member, a ground-side jig 3 as an example of a grounding member, a ground-side wiring 4 , and a detection-side wiring 5 .

[0035] The installation-side clamp 2 is provided at one end of the ground wire ...

Abstract

Provided is an earth device used for grounding an object to be earthed. An earth device is provided with: an earth side wire; a detection side wire which is not always conductive to the earth side wire; an attachment member which is provided on respective one ends of the earth side wire and the detection side wire so as to be attached to an object to be earthed, and conduct the earth side wire to the detection side wire; an earth member for grounding provided on the other ends of the earth side wire and the detection side wire; and a detection means connected to the detection side wire so as to detect the conduction of the detection side wire.

Description

technical field [0001] The invention relates to a grounding device for grounding a grounding object. Background technique [0002] A grounding device for preventing and eliminating charges may be connected to containers for storing volatile organic solvents and devices to which high voltage is applied. [0003] By grounding, for example, it is possible to solve the situation that the container is charged to generate static electricity and cause the organic solvent to ignite when handling organic solvents. For example, it is possible to eliminate the charge of the device applied with high voltage to prevent electric shock. [0004] As such a grounding device, for example, a grounding device has been proposed, which includes a grounding rod connected to the ground through a grounding wire, an auxiliary electrode connected to the grounding rod through an insulator and grounded through a wire, a display lamp installed in the middle of the wire, and the auxiliary electrode. It a...
