Description
The present invention relates to a latch type grounding apparatus used for checking or repairing a ceasefire facility, more particularly, to a grounding apparatus for a power supply facility, The present invention relates to a latch type grounding tool capable of securing the safety of a worker, increasing convenience and efficiency of work, and reducing labor costs due to shortening of time required for the work.
In general, the grounding equipment being used in the maintenance and repair work of the electric equipment is to be installed in the ground by means of the rail side fitting to be connected to the ceasefire equipment to be grounded during the ceasefire work for the inspection or repair of the electric power supply equipment or the water supply equipment. A grounding wire that connects to the grounding conductor and a grounding wire that connects the wire to the grounding wire.
Fig. 14 is a photograph showing a shape of a conventional line side metal fitting, Fig. 15 is a view schematically showing a state of a ground side metal fitting, and Fig. 16 is a cross- It is a photograph.
As shown in FIG. 14, the conventional line-side metal fitting includes a horizontal tightening bolt 100-6 and a vertical tightening bolt 100-6 for adjusting the distance between the body 100-1 and the tightening plate 100-8, 100-2, 100-7, a barbell gear 100-5, and horizontal / vertical tightening bolts 100-6 / 100-7. -3) and a vertical tightening ring 100-4.
In order to perform a grounding operation on a conductor (for example, a wire ACSR 480 mm 2) connected to a power facility that has been interrupted, first, the grounding of the grounding- The grounding bracket 30-1 is manually connected to the grounding conductor buried in the ground, the tightening lever 30-2 is turned clockwise by hand to fix the grounding-side metal fitting, The body 100-1 is inserted into the wire ACSR 480
When the ground is released, the second operation ring 40-2 is inserted into the horizontal / vertical tightening rings 100-3 / 100-4 of the line side metal fittings and the horizontal / vertical tightening bolts 100-6 / 100-7 The second operation ring 40-2 is pulled out of the body 100-1 and the
However, according to the conventional line side fitting to which the ground is attached or removed as described above, there is a problem in the grounding process and the grounding state according to whether the type of the grounding conductor is a wire or a conductor.
First, in case that the conductor to be grounded is an electric wire, in order to attach the line side metal fitting to the electric wire, it is necessary to attach a wire to the wire which is far from the grounding worker as much as the working distance (insulation distance between the grounding conductor and the worker, The body 100-1 is passed through the first operation ring 40-1 of the insulation bar, the first operation ring 40-1 is removed, the
In addition, when removing the rail side bracket from the wire, the rail side bracket is dropped to the ground due to the working conditions such as the weight and length of the rope, wind strength, and the limit of the worker's strength. The horizontal / vertical tightening bolts (100-6 / 100-7) projecting outwardly like horns due to the impact at this time are easily curved and can not be reused unless they are straightened. Therefore, in order to reuse the rail side metal fittings, And the threads of the horizontal / vertical tightening bolts 100-6 / 100-7 and the barbell gear 100-5 are worn out when the line fittings are used several times, And the fastening plate 100-8, which is a part where the line side metal fittings come into close contact with the electric wire, is often detached or lost, so that the time required for the grounding work is excessively long or delayed. do.
In addition, when the conductor to be grounded is of the same type, there are problems with the method and problem of attaching or removing the line side bracket to the same base, as well as the following problems.
In other words, since the distance between the end of the body 100-1 of the rail side metal fitting and the tightening plate 100-8 is only 60 mm at maximum, the width of the
