Description

{Apparatus of cable tray for preventing electric shock drawing at substation}

The present invention relates to a switchboard draw-out power cable insulated tray device supporting a plurality of switchboard power cables for drawing or drawing in / out of a building or switchboard in an insulated state of electricity in the distributed technology field. In detail, the present invention relates to a power distribution board insulated power cable insulated tray device having an insulated cable holder for supporting each of the cables in an insulated state.

On the other hand, there is no fluctuation in the installation position of the power distribution cable due to shock, vibration, earthquake, etc. applied from the outside to the power distribution cable installed in the cable holder, and it is relatively easy to maintain due to aging and automatically detects fire. It is a self-extinguishing system and promptly informs a designated manager of the current status, so that it is related to a power distribution board insulated power cable insulated tray device for follow-up.

In general, in a switchboard or building, a plurality of distribution wires (cables) for drawing power from the outside or drawing power from the inside is wired through a ceiling, a wall, etc., and these wires are guided by a cable tray. The incoming cable is connected and branched to the switchboard to supply electricity to the desired location.

In particular, in the case of the switchboard, a cable tray for guiding cables for distributing high-voltage electricity is used. The cable tray of the prior art for guiding such high-voltage wires (cables) has a structure in which a pair of mainframes are installed at regular intervals, and support frames are assembled at regular intervals between these mainframes.

The main frame has a structure in which an upper flange and a lower flange are formed at the upper and lower ends, and the support frame is formed in a channel shape, a curling portion (bended and folded) is formed at the end, and is assembled to the main frame by bolts. When the frame is fixedly installed on a wall of a building or the like, a number of wires are seated on the support frame and guided.

Normally, cable trays are installed in electrical use places such as switchboards, high-rise buildings, etc. so that the power required for power, light, and electric heating equipment can be drawn in and out, and a large amount of wires are placed and guided. Climbing or climbing using a ladder, etc., the cable is pulled from one side, the other worker supplies the cable from the other side, and the wiring work is carried out to arrange individual cables to be arranged according to a designated wiring path.

However, such a conventional cable tray occupies a large area as it is fixed to the ceiling on a flat surface, and when a large amount of cables are wired, a number of cable trays are complicatedly installed on the ceiling, and there is a problem that the appearance is not beautiful. When the cables are in contact with each other and used for a long time, the cable sheath is aging or the rodents such as rats break the cable sheath to expose the inner conductor of the wire, and the exposed conductor is shorted by contact with the metal cable tray. However, it is often known that workers who do not know these conditions cause safety accidents such as electric shock.

A cable tray made of high-strength synthetic resin has emerged as an insulating tray to solve this problem. However, such a tray also has a weak strength and is easily broken to support a plurality of high-load cables.

Therefore, it is necessary to solve the insulation problem to prepare for the above-mentioned safety accident while using the existing metal cable tray.

As a prior art that partially solves this problem, there is Korean Patent Application No. 10-2003-75355 (2003.10.28.), "A structure for preventing high voltage electric cable insulation using a tray box and a concrete box".

However, the prior art still leaves a problem that it is impossible to store individual cables and it is difficult to apply when the diameter of the cables is changed.

On the other hand, it is necessary to develop a technology that facilitates maintenance in the case of a cable that has been wired and installed, which needs to be replaced by a new cable due to aging due to long-term use, relocation due to design change, boosting, or the like.

In addition, if a fire occurs for various reasons in the cable tray, it is necessary to develop a technology to promptly notify the corresponding manager or system of fire and to automatically extinguish the fire itself.

Republic of Korea Patent Application No. 10-2003-75355 (2003.10.28.), "Structure for preventing high voltage electric cable insulation using tray box and concrete box" Republic of Korea Patent Registration No. 10-1199519 (2012.11.02.), "Insulated power cable insulated tray"

1 is a perspective view of a cable tray 100 according to a preferred embodiment of the present invention.

Referring to FIG. 1, the cable tray 100 for guiding and supporting the cable L is shown as a single unit, but it is preferable that a plurality of cables are installed on a certain channel. Moreover, it is preferable that the cable tray 100 is formed of a high-strength metal, which is more advantageous when used in a switchboard to which multiple cables of high load are applied. The above-described high-strength metal may include high-strength aluminum, plated steel, and the like.

The cable tray 100 is installed between a pair of vertical bars (101, 102) and a pair of vertical bars (101, 102) that are installed at regular intervals to space a pair of vertical bars (101, 102) at regular intervals. It includes a plurality of horizontal bars (103) connecting to. The horizontal bar 103 can be fixed by a process of screw fastening or riveting, not shown, with the vertical bars 101 and 102, and the cables can be connected by the vertical bars 101 and 102 and the horizontal bars 103. A space for loading and guiding is formed.

The horizontal bar 103 is provided with a cable holder 1 according to an embodiment of the present invention.

Since the cable holder 1 is installed in any one or more holder mounting holes 103 of the holder mounting holes 103 formed at regular intervals on the horizontal bar 103, the operator guides the cable L, so that the operator has a predetermined distance at a desired position. Cable L can be aligned.

Since the cable holder 1 supports the cable L and is installed to be spaced apart from the metal cable tray 100 at regular intervals, the insulation sheath of the cable L is corroded due to aging or rodents such as rats are insulated sheath. Even if the conductor of the cable is exposed by contact with the cable tray, it is not in contact with the cable tray 100 and is not energized or shorted. Therefore, the cable holder 1 is preferably formed of an insulating material such as synthetic resin. More preferably, the cable holder 1 may be formed of a flame retardant polyvinyl chloride (PVC) or a crosslinked polyethylene (XLPE) material, which is a flame retardant and insulating material.

2 is an exploded perspective view of the cable holder 1 applied to the cable tray 100 of FIG. 1 according to an embodiment of the present invention, and FIG. 3 is a cable tray 100 of FIG. 1 according to an embodiment of the present invention It is a sectional view of the main part of the cable holder 1 applied to the).

2 and 3, the cable holder 1 according to the present invention is divided into a first holder 10 and a second holder 20 to facilitate the installation of the cable L, and the first holder 10 and The second holder 20 is installed to be opened and closed by a hinge (hinge) 60 of a general configuration.

In the drawing, since the first holder 10 and the second holder 20 have the same configuration, the configuration of the first holder 10 will be mainly described and each of them will be described when necessary.

The first holder 10 includes a holder body 11 and a mounting body 12 extending downward from the holder body 11. The holder body 11 is formed with an 'C'-shaped mounting groove 111 inward, and a fluid 30 capable of flowing in the mounting direction is installed in the mounting groove 111. The fluid 30 is formed with a curved groove 312 on the cable support surface 311 to support the outer circumferential surface of the cable L to be fixed, and is installed to be pressed in the cable direction.

Therefore, a pair of guide grooves 113 are formed on the lower surface 112 of the mounting groove 111 of the first holder 10, respectively, and the fluid body can be guided by being seated in the guide groove 113. A pair of guide protrusions 316 are formed on the lower surface of 30). Similarly, a pair of guide grooves 113 are also formed on the upper side of the mounting groove 111, and a pair of guide projections 316 are also protruded on the upper surface 315 of the fluid 30 to form the fluid 30. It can induce stable flow.

The guide groove 113 described above is formed to have a locking jaw 114 so that the guide protrusion 316 of the mounted fluid 30 is completely moved out of the first holder 10 so as not to be separated. In addition, between the fluid 30 and the inner surface 116 of the mounting groove 111 of the first holder 10, a plurality of compression coil springs 50 are interposed to press the fluid 30 in the direction in which the cable is mounted. Was made.

Accordingly, spring support grooves 314 and 116 for supporting the compression coil spring 50 are provided on the rear surface 313 of the fluid 30 and the inner surface 115 of the mounting groove 111 of the first holder 10. Each is formed.

On the other hand, as in the first holder 10, the second holder 20 has the same fluid (40 in FIG. 4) pressurized by the compression coil spring 50 as described above, the first holder 10 ) And the second holder 20 are installed to be opened and closed with each other by a predetermined hinge 60.

In addition, the fluid holders 30 and 40 installed to be pressurized in opposite directions from the first holder 10 and the second holder 20 have curved grooves 312 and 412 formed on the cable support surfaces facing each other. Therefore, the cable L can be supported while being in close contact with the outer surface of the curved cable. At this time, when the diameter of the cable L is larger than the grooves 312 and 412 of the respective fluids 30 and 40, the fluids 30 and 40 are pushed to the outer circumferential surface of the cable, and the fluids 30 and 40 are moved into the mounting grooves of the respective holders 10 and 20. The fluids 30 and 40 are retracted under a certain pressing force. However, the mounting bodies 11 and 12 of each holder 10 and 20 can be in close contact with each other, and when mounted in the holder mounting opening 104 of the horizontal bar 103 in a closed state, fluids 30 and 40 ), The mounting bodies 12, 12 of each holder 10, 20 are firmly pressed against the holder mounting opening 104 of the above-described horizontal bar 103 because they press against each other. Can be fixed. More preferably, the locking projections 121 are formed on the outer circumferential surface of each mounting body 12, 22, and the locking grooves 105 are formed on the inner surface of the holder mounting opening 104 of the horizontal bar 103 to be coupled. When the bodies 12 and 22 are inserted and mounted in the mounting hole 104, the locking protrusion 121 is coupled to the above-described locking groove 105 in a forced fitting manner to assist in fixing the cable holder 1 securely. .

In this state, the operator can fix the cable holder 1 in a desired fitting manner among a plurality of mounting holes 104 formed on the horizontal bar 103 of the cable tray 100. At this time, since the locking protrusion 121 formed on the mounting body 12 is auxiliaryly caught in the locking groove 105 formed in the mounting hole 104, the solid mounting is completed. Although not shown, the same locking groove is formed in the mounting body 22 of the first holder 20.

Therefore, the cable (L) is arranged in a state spaced apart from the metal cable tray 100 by a predetermined distance by the cable holder (1) of an insulating material, the cable holder (1) continuously to each horizontal bar (103) ) Is applied, as a result, the cable does not come into contact with the cable tray 100 as a whole, thereby performing an insulation function.

However, the state in which the cable L is attached to the cable holder 1 is maintained, so that the mounting bodies 12 and 22 of the cable holder 1 are inserted into the holder fitting 104 in an interference-fitting manner to install in a fixed state. There were some problems in the process.

Second, even when the process of inserting the mounting bodies 12 and 22 into the holder mounting hole 104 was proficient, it was relatively difficult and time-consuming.

Third, after the cable L installed in the cable holder 1 is installed and installed, vibration generated in the cable L having a long length due to external vibration, shock, or earthquake is greater than the elastic force value of the compression coil spring 50 When the cable (L) is not fixed inside the cable halter (1) and is shaken in the left and right directions, the epidermis of the cable (L) directly contacting the grooves (312, 412) is damaged.

Fourth, in order to separate the cable from the cable holder in order to repair or replace the aging or damaged cable (L), the mounting bodies 12 and 22 must first be removed from the holder mounting portion 104, but from the holder mounting portion 104 It is very difficult to separate the mounting bodies 12 and 22.
