Description

Clamp Cover {CLAMP COVER}

The present invention relates to a clamp cover. Specifically, the present invention relates to a clamp cover that protects a clamping portion of a wedge-shaped tension clamp mechanism that clamps and fixes a high or extra high voltage distribution line.

The wedge-shaped tension clamp has been proposed to solve the problems caused by the weakening of the tightening force over time and construction inconvenience of the clamp fastened by the conventional U-shaped bolt. The wedge-shaped tension clamp is formed so that the distribution line tightening portion is formed in a wedge shape so that the tightening force is maintained or strengthened despite the passage of time by the tension of the distribution line, and the construction is simplified by tightening in the wedge shape. That is, the distribution line tightening portion is formed in a wedge shape so as to gradually narrow toward the side of the distribution line to which the tension is applied. Examples of such wedge tension clamps include Korean Utility Model Registration Nos. 152196, 298243, and 362772.

Tensile clamps used on high-voltage or extra-high voltage distribution lines have problems such as leakage or corona discharge due to the penetration of rainwater or foreign substances into the clamping portion for tightening the distribution lines. The same applies to the wedge tension clamp. Accordingly, it is necessary to surround the clamping portion of the tension clamp to prevent the penetration of rainwater or foreign matter, etc. Conventionally, a clamp cover as shown in FIG. 7 has been proposed.

The conventional clamp cover 1 is formed to cover not only the clamping portion but also the entire wedge-shaped tension clamp, and also the plastic insulator portion, which is bulky, high in manufacturing cost, and has to include a plurality of fasteners.

In addition, the cutting portion of the clamp cover is formed wider in accordance with the large volume, there was a problem that can not prevent the penetration of rain water or foreign matter more completely in the coalescing portion.

The present invention is to solve the above-mentioned problem, and to cover and protect only the clamping portion to substantially prevent rainwater or foreign matter penetration, not the entire wedge clamp to reduce the circumferential length of the incision and thus through the incision In order to reduce the possibility of rainwater or foreign matter penetration, and to make the volume smaller, the manufacturing cost will be lowered.

In addition, according to one aspect of the present invention by reducing the circumferential length of the incision to reduce the number of fasteners for fastening the incision to reduce the manufacturing cost.

Furthermore, according to another aspect of the present invention, a fluid outlet port is formed to discharge the fluid introduced into the interior or the fluid in the internal space through the microgap to the outside to prevent leakage or corona discharge caused by rain or foreign matter. We want to greatly reduce the occurrence.

Furthermore, according to another aspect of the present invention, an elastic body is coated on the coalesced portion of the incision cover to improve the sealing effect of the incision portion.

Furthermore, the flame retardant high-pressure insulating elastomer is coated inside the inlet and / or the outlet to effectively prevent rainwater or foreign matter from penetrating through the microgap between the inlet and / or the outlet and the distribution line.

In order to achieve the above object, according to one aspect of the present invention, the clamping portion of the wedge-shaped tension clamp mechanism for clamping the high-voltage or extra-high voltage distribution line inserted into the wire insertion portion is formed on the upper side is fixed A clamp cover for protecting, comprising: a left and right incision cover formed to be cut at the center of a central bending portion in a longitudinal direction of an upper portion thereof and closed or opened in accordance with folding or folding; An inlet formed by closing the left and right incision covers but having a tensioned distribution line; A draw-out port formed by closing the left and right incision covers and bypassing the distribution line side; Fixed fasteners formed at least on the inlet and the outlet, respectively, and fastened to close the left and right incision covers; And a lower hollow part forming a hollow to be in close contact with both side walls of the wire insertion part when the left and right incision covers are closed. Comprising, including the left and right incision cover is proposed to close the clamp cover to cover the clamping portion of the wedge-shaped tension clamp mechanism and the distribution line to be clamped.

In one embodiment of the present invention, the above-mentioned fixed fastener is formed in the lower portion of the inlet and the outlet and the upper portion of the inlet and the outlet.

In another embodiment of the present invention, the above-described lower hollow portion is formed with a fluid outlet formed in the lower direction so that the fluid is discharged from the inner space formed by the left and right incision cover is combined and closed.

Preferably, according to another embodiment of the present invention, the left and right incision cover is formed so that the stepped portion is formed on at least one side of the parts to be merged with each other overlapped when combined. More preferably, an elastic body including a rubber component is coated on at least a portion of the corresponding step portion and the stepped portion overlapped with the stepped portion at the time of coalescence.

Preferably, according to another embodiment of the present invention, each of the inlet and the outlet is characterized in that the flame-retardant high-pressure insulating elastomer is coated on the inside to compress and seal the power distribution line as the left and right incision cover is closed.

Preferred embodiments of the present invention include embodiments according to various possible combinations of the aforementioned technical features.

According to the design of the present invention, it is possible to cover and protect only the clamping part that should substantially prevent rainwater or foreign matter from entering the wedge-shaped clamp, thereby reducing the circumferential length of the incision and consequently penetrating rainwater or foreign matter through the incision. Can be lowered. Furthermore, the production cost can be lowered by reducing the volume.

In addition, by reducing the circumferential length of the incision according to one embodiment of the present invention it is possible to reduce the manufacturing cost by reducing the number of fasteners for fastening the incision.

Furthermore, according to another embodiment of the present invention to form a fluid discharge port to discharge the fluid introduced into the interior or the fluid in the interior space through the microgap to the outside. As a result, the occurrence of phenomena such as a short circuit or a corona discharge due to rain or foreign matter can be greatly reduced.

Furthermore, according to another embodiment of the present invention to cover the coalescing portion of the incision cover to improve the sealing effect of the incision.

Furthermore, according to another embodiment, it is possible to effectively prevent the ingress of rainwater or foreign matter through the micro-gap between the inlet or / and the outlet and the distribution line by coating a flame-retardant high-pressure insulating elastomer inside the inlet or / and the outlet. .
