And FIGS. 7 to 13 are perspective views illustrating a main booth separation process among the main booth replacement methods of the substation according to the present invention.

A method of replacing a main booth of a substation according to the present invention includes a step of fixing a frame (S100), a step of arranging a rail member (S110), a step of separating gas from a separation section, The main booth moving step S160, the main booth braking step fixing step S170, the main booth moving step S180, the bogie loading step S140, the gap compensating member inserting step S150, (S190). The main booth (10) can be removed and replaced to a replaceable position so that the main booth (10) of the gas insulated switchgear (GIS) can be replaced, And then moving it back to its original position.

The frame fixing step S100 is a step of fixing the main bus 10 to the support structure 110 in a direction perpendicular to the moving direction of the main booth 10 when the main bus 10 is required to be replaced, 2m).

At this time, the frame fixing step S100 is performed by welding or the like so that the front end of the frame 120 protrudes forward on both beams 112 (H-beams) of the supporting structure 110. [

The support structure 110 is formed by pouring concrete on the ground so that the main booth 10 and the like are installed. The support frame 12 of the main booth 10 is placed on the beams 112 buried in both sides, And a fastening block 114 of a metal material is fastened to be fastened by a fastening means 16 such as a bolt.

The rail member arranging step S110 is a step in which a pair of rail members 130 are spaced apart from each other in a direction corresponding to the moving direction of the main booth 10 on the upper surface of the frame 120 continuously disposed on the supporting structure 110 .

At this time, in the step of arranging the rail members S110, one of the rail members 130 is positioned outside the seating frame 12 disposed on one side of the main booth 10, Is positioned inside the seating frame (12) disposed on the other side of the booth (10).

When the rail member 130 is positioned on the inner frame 12 in consideration of the fact that the spacing between the seating frames 12 provided at four positions on the bottom of the main booth 10 is determined, The spacing between the seating frame 12 and the rail member 130 does not correspond to the spacing between the seating frame 12 and the rail member 130. Therefore,

Here, the frame 120 and the rail member 130 are made of a material such as a "C" Since the rail member 130 is extended so as to protrude further than the end portion of the main booth 10 by a predetermined interval of 5 m, the main booth 10 can be moved to the protruding end, .

The gas recovery, contact, and facility separation steps S120 of the separation section are performed to recover the gas flowing in the interior of the main booth 10 in the dismantling work section and to separate the contacts of the control cable in the main booth 10, And so on.

Here, the contact separation of the control cable is performed while the inspection window of the main booth 10 is opened.

In the support structure separation step S130 of the main frame booth fixing frame 14 connecting the seating frame 12 of the main booth 10 and the connection block 114 provided in the support structure 110, Is first removed by welding or the like so that the support frame (12) of the main booth (10) can be detached from the support structure (110).

When the main booth 10 starts to move by the movement of the bogie 140, the contact point is separated from the main booth 10 and is moved to the midpoint position, and then the bogie 10 is replaced with a crane or the like And the main booth 10 is charged.

Meanwhile, the method of reassembling after replacing the main booth 10 for reasons such as installation and restoration work is performed in the reverse order of the separation method, and the main booth 10 is moved in the reverse order (S200) S210), a main booth moving step S220 to a main booth fixing position, a gap compensating member separating step S230, a car take-off step S240, a seating frame attaching step S250 of the main booth to the support structure, (S260), a rail member separation step (S270), and a frame separation step (S280).

In the step S200 of moving the main booth, the main booth 10 which has been replaced is pulled backward in the home position through a winch or the like so that the bogie 140 moves along the rail member 130 .

The main booth and the bogie separation step S210 are a step of separating the fastening means 16 such as a bolt or the like which fastens the mounting frame 12 of the main booth 10 to the main booth fixing portion 144 of the bogie 140 .

The main booth moving step S220 of moving the main booth to the main booth fixing position pulls the seating frame 12 of the main booth 10 backward using a lifting device such as a lever block, The main booth 10 is moved so that the seating frame 12 of the main booth 10 can be positioned above the fastening block 114 of the main booth 10.

The gap correction member separation step S230 is a step of separating the gap correction member 150 such as a liner or the like that has filled the gap generated between the seating frame 12 of the main booth 10 and the upper surface of the carriage 140. [

The main booth 10 is lifted up to a predetermined height and the bogie 140 is mounted on the bottom of the main booth 10 in the seating frame of the main booth 10, (12).

In the step S250 of attaching the main frame to the support structure, the mounting frame 12 of the main booth 10 is placed on the upper side of the fastening block 114 of the support structure 110 after separation of the bogie 140 The mounting frame 12 of the main booth 10 and the fastening block 114 provided on the supporting structure 110 are joined by welding or the like by the upright booth fixing plate 14. [

The gas supply, contact, and facility combination step S260 of the coupling section is performed by connecting various facilities such as the gas supply to the connection work section of the main booth 10, the contact separation of the control cable in the main booth 10, and the ladder .

The rail member separation step S270 is a step of separating the pair of rail members 130 from the frame 120 disposed on the support structure 110. [

The frame separation step S280 is a step of separating the frame 120 disposed on the support structure 110 at predetermined intervals by welding or the like.

The main booth replacement apparatus 100 for implementing the main booth replacement method of the present invention includes a frame 120, a rail member 130, and a carriage 140.

The frame 120 is formed by a method such as welding such that a plurality of beams are projected forward at a set interval (for example, 2 m) in a pair of beams 112 embedded on a support structure 1210 on which the main booth 10 is supported As shown in Fig.

The support structure 110 is formed by placing concrete on the ground so that the main booth 10 and the like are installed. The support frame 12 of the main booth 10 is mounted on the beam 112 buried in both sides, The fastening block 114 of the metallic material is joined.
