Each of the plurality of ground units 200 includes a ground member 210 electrically connected to the power distribution line 110, a ground member 210 fixed to the ground 1 and detachably connected to the ground member 210, A grounding device 220 for grounding the distribution line 110 through a member 210 and connection sensing means 230 for sensing a connection state between the grounding device 220 and the grounding member 210.

The grounding members 210 are formed as a pair and are arranged to be in contact with each other and are coupled through bolts (not shown).

A connection terminal is formed in each of the pair of ground members 210, and an end of the distribution line 110 is connected to the connection terminal.

Accordingly, when the pair of ground members 210 are coupled to face each other, each connection terminal is connected.

The grounding unit 220 includes a grounding body 221 having a circular plate shape, a plurality of embedding members 222 extending from the lower end of the rim of the grounding body 221 and fixedly embedded in the ground 1, A connection end 223 formed at the upper end of the grounding member 210 and screwed to the lower end of the grounding member 210; a grounding member 210 formed inside the grounding body 221 and made of metal, And the other end is protruded through the lower ends of the plurality of embedding members 222 and is buried in the ground 1.

The connection detecting means 230 is installed between the lower end of the grounding member 210 and the upper end of the inner grounding member 224 and is connected to the lower end of the grounding member 210 and the inner grounding member 224 And a pressure sensor for measuring the pressure between the upper ends of the pressure sensors.

Therefore, not only the fixing force in the ground of the grounding device 220 is improved but also the fixing force forming area and the grounding area can be increased by screwing the cone body 224a to the ground 1.

The motor 500 is driven by a control signal of a controller 320, which will be described later.

The motor 500 is installed at the lower end of the inner grounding member 224 and the motor shaft of the motor 500 is disposed to face downward. The center is connected.

When the motor 500 is driven, the motor shaft is rotated and the cone body 224a connected to the motor shaft is rotated to rotate.

According to the present invention, it is possible to monitor the grounding state in the distribution line of each complex in real time, and to increase the contact area in the ground in the distribution line to improve the grounding efficiency.

In addition, it is possible to immediately shut off the power distribution line at the power distribution part where the ground fault occurs, thereby effectively preventing the electric shock accident of the manager in the ground fault state.

In the present invention, the structure of the horizontal holding unit 400 for holding the horizontal position by pressing the grounding unit 220 as shown in FIGS. 6 to 8 is implemented.

The horizontal holding unit 400 includes a base plate 401 positioned on the upper side of the grounding unit 220 and passing the grounding member 210 inwardly, A plurality of pressing bars 402 penetrating the base plate 401, a pressing plate 403 connected to the upper portions of the plurality of pressing bars 402 and passing the grounding member 210 inwardly, And pressing means (404) for pressing the plate (403).

The base plate 401 is in the form of a plate-like ring, and is seated on the upper surface of the ground 1, that is, the ground surface 2.

A plurality of through holes 401a penetrating in the up and down direction are radially formed on the center of the base plate 401. The plurality of pressure bars 402 are vertically movable in the plurality of through holes 401a .

The presser bar 402 may be fitted around the through hole 401a and a tightening ring 405 may be provided to hermetically seal the presser bar 402 with the presser bar 402.

The base plate 401 may be formed with a plurality of protrusions 401b which are drawn into the ground 1 on the lower surface thereof so as to maintain a stable state on the ground surface 2. [

It is preferable that the protrusion 401b has a conical shape whose diameter decreases from the top to the bottom.

It is most preferable that both ends of the pressure bar 402 extend in the vertical direction, and the cross section has a circular shape.

The horizontal holding part 400 includes a plurality of bushings 406 extending downward from the base plate 401 and having upper and lower portions opened to communicate with the through holes 401a and embedded in the ground 1, As shown in FIG.

The bushing 406 preferably has an inner diameter larger than an outer diameter of the pressure bar 402.

The plurality of pressure bars 402 are drawn into the plurality of bushings 406 and pressurized by the pressure means 404 to reliably press the grounding device 220 without departing to the outside or friction with the outside . Here, friction with the outside can be understood as friction with the ground 1 or the like.

The pressing plate 403 is positioned on the upper side of the base plate 401 and has the same shape as the base plate 401.

The pressing plate 403 may extend downward from the lower surface and may have a plurality of pulling members 407 which are opened to the inside and into which the plurality of pressing bars 402 are inserted.

The pressing means 404 is preferably a cylinder 404a and a plurality of pressing means 403 are disposed on the upper surface of the pressing plate 403 along the circumference.

The cylinder 404a can be understood as a general type of hydraulic or pneumatic cylinder.

The cylinder 404a is eccentric to one side with respect to the center of the pressing plate 403 and presses the other side protruding upward, so that the pressing plate 403 can keep the pressing plate 403 in a horizontal position.

To this end, it is preferable that the present invention further includes a horizontal sensing sensor 408 for sensing the eccentric state of the pressing plate 403.

The horizontal sensing sensor 408 senses a horizontal state in which the pressing plate 403 is horizontal and an eccentric state in which it is eccentrically eccentric to one side and the controller 320 controls the pressing means 404 in accordance with the sensing signal. The other side of the pressing plate 403 is pressed or the driving is stopped.

It goes without saying that all or a part of the plurality of cylinders 404a may be driven under the control of the controller 320. [

This prevents separation and separation between the grounding device 220 and the grounding member 210 that may occur due to the failure of the grounding device 220 to maintain the horizontal position, So that monitoring can be smoothly performed.

Therefore, the eccentric state of the pressing plate 403 is a state in which the grounding body 221 is eccentrically unilaterally and the horizontal state of the pressing plate 403 is a state in which the grounding body 221 is horizontal And the horizontal sensing sensor 408 may be provided on the pressing plate 403 or on the grounding body 221.

The pressing means 404 presses the pressing device 402 against the pressing device 403 in accordance with the pressing force of the pressing device 403 so that the eccentric grounding body 221 is horizontal.

When the pressing plate 403 is horizontal, the controller 320 senses the horizontal sensing signal of the horizontal sensing sensor 408 and stops driving the pressing unit 404.

Accordingly, the grounding device 220, which is buried in the ground, is maintained in a horizontal state, so that the grounding device 220 and the grounding member 210 can be stably maintained without being separated and separated from each other The monitoring by the ground monitoring unit 300 can be performed smoothly.
