Description

[0001] UNDERGROUND LINE CONNECTOR [0002]

The present invention relates to a ground distribution line connection connector having a branching function for preventing an accident such as an electric shock while maintaining a stable connection state between a main line and a branch line via a branch sleeve.

In general, electric power lines are installed in electric poles or buried in the ground in order to supply electric power. The ground and airborne type are much more economical than the method of buried in the ground in consideration of the workability, the construction cost and the construction period Although there is an advantage that construction can be simplified, it is disadvantageous that it is difficult to install in a place where buildings are very close to each other, such as a downtown area.

For example, in a power plant including a thermal power plant, a hydroelectric power plant, and a nuclear power plant, electricity generated at a voltage of about 20,000 V is boosted to ultra high voltage (154 KV or 345 KV) suitable for transmission, To the primary substation. The primary substation will drop the super-high voltage electricity to 22.9 KV, which is the special high voltage, and transmit or distribute the electricity to the general customers along the second substation or underground distribution line located near the large-capacity customer.

The electricity distributed from the first substation or the second substation is transmitted or distributed to the reception facilities of each customer through the transmission and distribution system composed of the underground distribution line and the underground distribution line. Through the special high pressure customer, the high pressure customer and various outdoor installation transformers, It is used for industrial and home use.

Generally, in the transmission and distribution system using the ground, an underground pipe is arranged in the ground so as to keep a certain distance in the up and down and right and left directions, and a cable or underground distribution line for transmitting electric power to the hole formed in the underground pipe is installed. Transmitting and distributing extra high voltage through. The above-mentioned underground pipes must be kept in a constant spacing, and it is difficult to maintain a uniform spacing of the ground.

A plurality of shelves for accommodating a plurality of wires (for example, extra-high voltage wires, communication cables, etc.) are arranged at regular intervals in the underground tube, and underground distribution lines are mounted on the shelves, Lt; / RTI >

Regarding such a power supply method, the Korean Patent Registration No. 0881352 discloses a technology for preventing the shortening of the life of the underground distribution line due to leakage of the concrete structure and the electric accident in advance, Discloses a "distribution line forming panel of an extra high voltage underground wire" comprising a shelf for preventing flow.

On the other hand, in order to extract electric power from the underground distribution line and distribute it, a branch sleeve, which is a kind of connector, is constituted, and the live branching loop is drawn out from the branch sleeve. A branching line for electrically connecting the underground distribution line and the transformer is wired through the extracted branching loop, and the electricity in the underground distribution line is supplied to the transformer through the branching line to be output to the electricity of the designated voltage.

However, since the conventional branch sleeve is a section where the underground distribution line and the branch line are wired together, it is protected by wrapping it with a separate safety cover to prevent leakage or other safety accidents. However, all of these conventional techniques have a structural limitation in that workability is lowered due to the assembly of the safety cover or the like by bolts and nuts, and it is not easy to connect and disassemble the branch lines to the live branching loop.

The connecting connector S of the above-described embodiment will be described in more detail.

As shown in FIG. 1, the connection connector S is a branch sleeve for branching the branch line LW from the underground distribution line SW, and is easy to disassemble and assemble, ) And the branch line (LW).

2, the live wire SW and the branch wire LW are shown as simple cross-sectional views for the sake of simplification of the drawing, but the actual wire SW and the branch wire LW are not necessarily essential It should be understood that the wire and the cover to be constructed are not absent from this embodiment, and that the live wire SW and the branch wire LW are well-known cables.

3 is a perspective view showing the wrapper configured in the connector according to the present invention.

The connection connector S includes a branch sleeve 100 that keeps the ground connection line SW and the branch line LW in contact with each other to maintain a tight connection state. To this end, the branch sleeve 100 is formed into a curved plate shape so as to surround the underground distribution line SW, and a plurality of engagement projections 111 and 111 'are formed at regular intervals along the left and right edges, The engagement protrusion 111 of the edge and the engagement protrusion 111 'of the left edge include the wrapper 110 arranged to be interlaced with each other. Here, the engaging projections 111 and 111 'constitute the through holes 111a and 111a', respectively, and the through holes 111a and 111a 'are formed to open toward the adjacent engaging projections 111 and 111'. Therefore, when the left and right coupling protrusions 111 and 111 'are mated to each other, the through holes 111a and 111a' of the adjacent coupling protrusions 111 and 111 'communicate with each other in a line. Furthermore, the positions of the through holes 111a and 111a 'in the engaging projections 111 and 111' are determined such that when the rapper 110 completely engages the underground distribution line SW and the branch line LW, the through holes 111a and 111a ' ), The operator tightens the wrapper 110 to a position where the through holes 111a and 111a 'communicate with each other in the field.

The wrapper 110 integrally encloses the underground distribution line SW and the branch line LW and presses the underground distribution line SW and the branch line LW in intimate contact. For this purpose, the wrapper 110 is shaped like a curved plate of soft and elastic material.

On the other hand, in order that the wrapper 110 wrapping the underground distribution line SW and the branch line LW receives the external force and can closely contact the underground distribution line SW and the branch line LW, The projections 111 and 111 'are formed at regular intervals. At this time, the engagement protrusions 111 and 111 'are arranged in the wrapper 110 such that the engagement protrusions 111 of the right edge and the engagement protrusions 111' of the left edge are offset from each other, The engaging projection 111 of the right edge and the engaging projection 111 'of the left edge are alternately crossed with each other. Accordingly, as the wrapper 110 receives external force, the cross-sectional area narrows without mutual interference of the engaging projections 111 and 111 '.

Shaped fixed beams 113 (111a, 111b ') are formed in the through holes 111a, 111a' so that the engagement protrusions 111, 111 'at the left and right edges of the through holes 111a, 111a' ). Therefore, the fixed beam 113 penetrates along the through holes 111a and 111a 'of the engagement projections 111 and 111' positioned in a row and performs a latching function through which the engagement projections 111 and 111 ' Maintains the gripping force of the line (SW) and the branch line (LW). A bolt (not shown) is formed at both ends of the fixed beam 113 to prevent the fixed beam 113 inserted into the through holes 111a and 111a 'from re-releasing, and a nut shape So that the fixed beam 113 passing through the through holes 111a and 111a 'can be maintained in a state in which the fixed beam 113 passes through without being re-released.

FIG. 4 is a front view showing the first press and the second press of the connector according to the present invention, and FIG. 5 is a perspective view showing the first and second presses shown in FIG.

The branch sleeve 100 of the present embodiment includes a first curved panel 141 of conductive material surrounding the underground distribution line SW and a second curved panel 141 which surrounds the branch line LW and is fixed to be symmetrical with the first curved panel 141 A first press (140) composed of a curved panel (142) and inserted into the wrapper (110); A first pressing surface 151 that surrounds the first curved panel 141 and a second pressing surface 152 that surrounds the second curved panel 142 respectively constitute a first pressing surface 151 in the wrapper 110, And a pair of second presses 150 disposed symmetrically to the left and right about the first and second presses 140.

The first curved surface panel 141 of the first press 140 has a bowl shape for seating the underground distribution line SW and is made of a conductive material so as to be in direct contact with the underground distribution line SW, . In addition, the first curved panel 141 receives the pressure of the wrapper 110 and tightly surrounds the outer surface of the underground distribution line SW where the coating is peeled off.

The second curved panel 142 of the first press 140 is made of an electrically conductive material so that the cover is in direct contact with the stripped branching wire LW and is electrically connected. In the present embodiment, the second curved panel 142 is disposed at the center of the bottom surface of the first curved panel 141 and integrally formed with the first curved panel 141. Therefore, electricity of the ground distribution line SW is conducted through the first curved panel 141 and the second curved panel 142 to the branching line LW.

The second press 150 includes a first pressing surface 151 for covering the first curved panel 141 and a second pressing surface 152 for covering the second curved panel 142. Also, a pair of the second presses 150 are arranged symmetrically to the left and right about the first press 140 as shown in FIG.

The left and right portions of the first curved panel 141 are in contact with the first pressing surface 151 and the left and right portions of the second curved panel 142 are in contact with the second pressing surface 152 , The first curved panel 141 and the second curved panel 142 are brought into intimate contact with the ground distribution line SW by receiving the external force of the wrapper 110.

Since the second presses 150 and 150 'receive the pressure of the wrapper 110 and apply pressure to the outer surface of the first press 140, the second presses 150 and 150' are not necessarily made of a conductive material, So that the electrical connection between the underground distribution line SW and the branch line LW can be mediated.

Since the second press 150 and 150 'in this embodiment simultaneously contact the first curved panel 141 and the second curved panel 142, the first pressing surface 151 is pressed against the second press 150 and 150' And the second pressing surface 152 is located on the side of the second press 150, 150 '. As a result, the wrapper 110 directly presses the second presses 150 and 150 'and the second presses 150 and 150' press the first presses 140 so that the first presses 140 It is brought into intimate contact with the distribution line SW and the branch line LW.

6 is a front view sequentially showing a state where the rapper and the first and second presses electrically and mechanically connect the underground distribution line and the branch line.

The branch sleeve 100 of the present embodiment includes shoulders 120 and 120 'formed to protrude from the front and rear central portions of the wrapper 110, respectively. The rapper 110 is disposed in parallel with the shoulders 120 and 120 'so as to press the left and right edges of the engagement projections 111 and 111' crossing each other while wrapping the underground distribution line SW in the tightening direction And a shaft (130).

The underground distribution line SW and the branching line LW and the first and second presses 140, 150 and 150 'are superimposed on each other while the wrapper 110 is wrapped around the underground distribution line SW and the branch line LW, The engaging projections 111 and 111 'are staggered from each other as shown in FIG. 6 (c). At this time, the shaft 130 is disposed side by side with the shoulders 120 and 120 'and positioned between the engaging projections 111 and 111' of the left and right edges engaged with each other. Therefore, when the shaft 130 receives a pressure in the direction of the shoulders 120 and 120 ', the shaft 130 applies a pressure toward the intersection of the engaging projections 111 and 111' which are staggered with each other, and the left and right engaging projections 111, 111 'are pushed by the pressure exerted by the shaft 130, so that the engagement state becomes closer. Of course, in this process, the curl of the wrapper 110 becomes larger, and the pressure applied to the first and second presses 140, 150 and 150 'becomes stronger. Of course, the tightness between the underground distribution line SW and the branch line LW via the first and second presses 140, 150 and 150 'becomes strong, thereby achieving a stable electrical connection. That is, by merely applying a pressure to the shaft 130, an efficient electrical / mechanical connection state is established between the underground distribution line SW and the branch line LW.

Will be further described with reference to Fig.

The housing 200 of the present embodiment has a curved shape that covers and presses the upper surface of the shoulders 120 and 120 'and a pair of first flanges 211 and 211' are formed along both side edges of the curved surface A loop 210 having magnetic panels 212 and 212 'fixed to the bottom surfaces of the first flanges 211 and 211'; A pair of second flanges 221 and 221 'are formed along both side edges so as to face the first flanges 211 and 211', respectively, and the second flanges 221 and 221 ' A bottom 220 secured to the upper surface of the flanges 221 and 221 'and having magnetizing panels 222 and 222' bonded to the magnetic panels 212 and 212 'by the magnetic force of the magnetic panels 212 and 212'; .

As described above, when the underground distribution line SW, the first and second presses 140, 150 and 150 'and the branch line LW are connected by the wrapper 110, the housing 200 surrounds the corresponding components .

The housing 200 according to the present embodiment includes a loop 210 and a bottom 220. The loop 210 covers the upper surface of the wrapper 110 and supports the shoulders 120 and 120 ' The upper surface is pressed. The loop 210 of the present embodiment may have a structure that completely covers the upper surface of the wrapper 110 but a belt shape that covers only the shoulders 120 and 120 'other than the wrapper 110 may be formed.

Subsequently, the bottom 220 covers the lower surface of the shaft 130 and presses it.

When the loops 210 and the bottoms 220 are joined to each other and the shoulders 120 and 120 'and the shaft 130 are pressed respectively, the underground distribution line SW and the sub- The branch lines LW are electrically / mechanically connected to each other.

On the other hand, the magnetic panels 212 and 212 'and the magnetization panels 222 and 222' are formed on the first flanges 211 and 211 'of the loop 210 and the second flanges 221 and 221' The magnetization panels 222 and 222 'are magnetically joined to the magnetic panels 212 and 212' so that the loop 210 and the bottom 220 are joined to each other to press the wrapper 100 upward and downward, (210) and the bottom (220) are coupled to each other.

As a result, when the first flanges 211 and 211 'of the loop 210 and the second flanges 222 and 222' of the bottom 220 face each other, the operator can move the magnetic panels 212 and 212 ' The loops 210 and the bottoms 220 are integrally coupled to each other by a magnetic force between the first and second housings 222 and 222 '. When the operator pulls the loop 210 and the bottom 220 with a tension greater than the magnetic force so as to disassemble the connector S, the loop 210 and the bottom 220 are separated from each other.

Of course, since the gripping force of the wrapper 110 is maintained by the fixed beam 113, the elastic force of the wrapper 110 to be loosened does not directly affect the housing 200.

While the present invention has been described in connection with what is presently considered to be practical exemplary embodiments, it is to be understood that the invention is not limited to the disclosed embodiments, but, on the contrary, It will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined by the appended claims.
