Description

Compression clamp for power transmission line {a compression type clamp for fixing a power cable}

The present invention relates to a compression clamp for fixing a transmission line to accommodate the conductive compound on the inner surface of the pipe body when manufacturing the pipe body of the compression clamp used in the construction of the transmission line.

More specifically, the conductive compound contained in the inner side of the pipe body is uniformly applied between the outer side of the transmission line and the steel clamp and the inner side of the pipe body during compression molding of the pipe body by means of a compressor. The present invention relates to a transmission clamp for clamping a transmission line to increase the conductivity of a transmission line and to prevent the uncompressed portion and the uncompounded portion from being blown with moisture generated by temperature differences in winter.

In general, when constructing a transmission line for supplying electricity, a plurality of compression clamps are installed at the end of the transmission line in order to maintain a good tension state of the transmission line. The compression clamp supports the end of the transmission line and simultaneously It is a device that preserves the state of the connection part well.

The above-described compression clamp is manufactured as a high-purity aluminum (Al) material having high conductivity so as to maintain durability against vibrations due to the weight of the power transmission line itself and wind pressure and to transmit electricity of good quality.

As shown in Figures 1 to 3, the transmission line fixing compression clamp 10 according to the prior art, the steel core 1a of the power transmission line 1 (a part of the aluminum wire is peeled off) is not shown Strong core coupling portion 2 formed to be compressed and fixed by a hydraulic compressor (approximately 100 tons of compression force applied in the radial direction), and uneven portion 3 and uneven portion formed on the upper core coupling portion 2 Steel clamp (5) consisting of a connecting ring (4) formed by maintaining a certain distance from the portion (3),

It is fixed to the outer surface of the steel clamp (5) and includes a pipe body (6) to secure a certain length so as to surround a portion of the power transmission line (1).

That is, the compression clamp 10 is installed to support the end of the electric wire of the catenary angle of the transmission line 1 in the transmission tower pylon 7, the jumper wire (8) in the lower portion of the compression clamp 10 The jumper terminal 9 is connected to be connected to the power transmission line 1 to be conducted.

Therefore, when constructing a transmission line, the steel core 1a of the transmission line 1 is fixed using the compression clamp 10. After coupling the steel core 1a to the steel core coupling portion 2 of the steel clamp 5 and pressing the steel core 1a into a hexagon by a compressor, the compressed steel clamp 5 is joined to the pipe body 6, and the pipe body 6 After injecting the conductive compound into the space of the strong core coupling portion (2) through the compound inlet (not shown) formed in () to inject the conductive compound of the grease system using the injection gun), the inlet is sealed with a stopper. .

The pipe body 6 in the section excluding the above-described strong core coupler 2 is pressed into a hexagon using a compressor to fix the steel clamp 5 to the pipe body 6. As a result, the uneven part 3 of the steel clamp 5 is compressed, and the strong core coupling part 2 can be crimped and connected in the longitudinal direction to the connection part of the power transmission line 1 without being compressed again.

At this time, the worker who climbs on the power transmission line 1 directly injects the conductive compound into the space of the strong core coupling part 2 and works in an unstable posture. (1) has a problem that can cause a safety accident that falls from the injury.

Alternatively, when the conductive compound is applied to the outer surfaces of the steel clamp 5 and the steel core 1a by hand, and then the steel clamp 5 is pressed and fixed to the pipe body 6, the conductive compound is the steel clamp 5 ) Is not uniformly applied to the core and the core (1a) has a problem of low conductivity and reliability of the power transmission line (1).

On the other hand, since the pipe body 6 described above is broken due to freezing or the connection portion of the jumper terminal 9 to which the jumper wire 8 is connected is melted and broken due to overheating, the compression clamp 10 is periodically replaced. Done.

That is, in the compression clamp structure for fixing the transmission line according to the prior art, when the primary compression portion of the steel clamp (5) formed by hexagonal compression is coupled to the pipe body (6), the steel clamp (5) is pressed again 1 Since plastic deformation can be generated in the differential compression region, a non-compression region is generated between the steel clamp 5 and the pipe body 6.

Therefore, when the catenary angle is an incidence in the barrier system of the power transmission line, the water flowing through the gap between the power transmission line 1 and the pipe body 6 is caused by the gap due to the non-compression part of the compression clamp 10 ( Go to G). Alternatively, when the amount of blisters generated due to the temperature difference in winter accumulates in the gap G, the pipe body 6 may be frozen and broken. As a result, the tensile strength of the compression clamp 10 may be reduced, or a disconnection failure may occur due to oxidation corrosion of the stranded wire.

Therefore, due to the frequent replacement work of the compression clamp 10 has a problem that the after-care costs are required due to the numerous costs and working hours.

In the embodiment of the present invention, when the steel core of the transmission line is crimped and fixed to the pipe body by the compression molding by the compressor, the conductive compound contained in the inner surface of the pipe body between the outer surface of the transmission line and the inner surface of the pipe body Since the coating is uniformly applied to the transmission line, it is related to a transmission clamp for clamping the transmission line, which increases the conductivity of the transmission line and makes it reliable.

In the embodiment of the present invention, since the conductive compound is filled in the gap between the steel clamp and the pipe body due to the non-compression portion of the pipe body, the moisture generated due to the temperature difference in the winter to prevent the damage caused by freezing It is associated with a compression clamp for securing transmission lines that can be prevented.

The embodiment of the present invention is fixed to the transmission line to improve the workability of installing the compression clamp because the work process of applying a conductive compound on the surface of the transmission line by the operator is unnecessary to install the compression clamp when constructing the transmission line For compression clamps.
