Description

배전선로 저압모선 {The bus for the distribution line of low voltage}Distribution Line Low Voltage Bus {The bus for the distribution line of low voltage}

배전선로 전선연장기술 관련 분야Distribution line cable extension technology

저압배전선로에서는 전력을 공급하기 위하여 주상변압기 인하선의 선로에 연결, 기설선로에 신설선로의 연결, 인입선의 배전선로에 연결 등에 다양한 방법으로 선로 분기작업을 시행하고 있다.    In order to supply electric power, low-voltage distribution lines carry out branching work in various ways, such as connecting to the lower line of the column transformer, connecting the new line to the existing line, and connecting to the distribution line of the incoming line.

기존에는 배전선로에는 저압모선에 해당하는 설비가 존재하지 않는다. 분기성로를 형성시킬 필요가 있을 경우 인근의 선로에 분기슬리브(16)를 사용하여 분기선로를 연결하였다. 분기슬리브(16)를 시공한 장소가 힘을 받는 주선로인 경우 분기슬리브(16)가 시공된 부위와 그 주변의 전선의 유연성이 달라져서 바람에 횡진이 많을 경우 전선이 끊어지는 사고도 발생할 수 있다. 또한 정해지지 않은 장소에서 분기선로를 무계획적으로 연결함으써 미관을 해칠 수 있으며, 기존 선로가 신설선로보다 가는 경우 기존선로 일부에 과부하 부위가 발생할 있다.Conventionally, there are no facilities for low voltage busbars in distribution lines. When it is necessary to form a branching path, a branching sleeve 16 is used to connect a branching line to a nearby track. In case where the branch sleeve 16 is constructed as a main line, the flexibility of the wires around the branch sleeve 16 is changed, and if there is a lot of traverse in the wind, the wire may be broken. . In addition, by unintentionally connecting branch lines in unscheduled places, the aesthetics can be damaged. If an existing line is longer than a new line, an overload part may occur in an existing line.

본 발명에서는 저압배전선로에 변전소의 모선과 동일한 개념의 저압모선을 도입하고자 한다. 분기선로가 필요한 경우 모선을 새롭게 만들어 설치함으로써 분기선로를 저압모선에서 순차적으로 분기하도록 하여 전선의 허용전류를 넘지 않게 하고 장력을 받는 주선로가 아닌 저압모선에서 분기선이 분기되도록 하여 접속부위에 힘이 가해지지 않도록 하여 안정된 선로구성을 할 수 있게 한다.       In the present invention, a low voltage bus having the same concept as a bus bar of a substation is introduced into the low voltage distribution line. If a branch line is needed, a new bus is installed and installed so that the branch line branches sequentially from the low voltage bus so that it does not exceed the allowable current of the wire and the branch line branches from the low voltage bus instead of the main line under tension. It is not applied so that stable line construction can be achieved.

또한 고객의 숫자가 많은 소규모수용가들의 인입선을 효과적으로 처리할 수 있는 편리한 모선을 제시하도록 한다.It also suggests a convenient busbar that can effectively handle the incoming line of small number of customers.

절연된 도체를 활용하여 저압모선을 만들고 기존전선에 모선지지밴드로 고정시킴 Low voltage bus is made by using insulated conductors and it is fixed by bus support band to existing cable.

본 발명에서는 배전선로에 저압모선의 개념을 새롭게 도입하였다. 모선(21)의 개념이 없었던 지금까지는 분기선로를 형성할 때 기존선로(15)의 장력을 약화시키거나 과부하구간(19)을 유발시키거나 미관을 해치는 단점이 유발되었다.      In the present invention, the concept of a low voltage busbar is newly introduced into a distribution line. Until now, there was no concept of the mother bus 21, so that when forming the branch line, the disadvantage of weakening the tension of the existing line 15, causing an overload section 19, or damaging the aesthetics.

본 발명에서는 저압모선의 개념을 도입함으로써 분기선로를 저압모선에서 순차적으로 분기시킴으로써 전선의 허용전류를 넘지 않게 하고 장력을 받는 주선로가 아닌 저압모선에서 분기선이 분기되도록 하여 접속부위에 힘이 가해지지 않도록 하여 안정된 선로구성을 할 수 있게 하였다. 또한 고객의 수가 많은 소규모수용가들 을 위하여 소선다발(51)이 연결된 저압모선을 제시하여 간편하게 많은 소규모수용가들의 인입선을 연결하도록 하였다. 특히 모선을 기존선로에 메달도록 시공하여 별도의 저압모선 설치장치와 장소를 필요로 하지 않도록 하여 비용과 인력 사용을 획기적으로 줄였다.In the present invention, by adopting the concept of low voltage bus bar, the branch line is sequentially branched from the low voltage bus bar so as not to exceed the allowable current of the wire, and the branch line is diverged from the low voltage bus bar instead of the main line under tension, so that the force is applied to the connection part. It is possible to make a stable line configuration. In addition, for the small number of customers with a large number of customers, the low-voltage bus bar is connected to the small wire 51 to easily connect the incoming line of many small number of recipients. In particular, by constructing the bus to hang on the existing track, it eliminated the need for a separate low voltage bus installation device and place, thereby drastically reducing the cost and manpower use.

도 1은 기존 주상변압기 2차인하선 연결오류 설명도이다. 전주(12)에 설치된 주상변압기(11)에서 전압인하선(13)과 접지인하선(14)이 인출되어 하부의 기존선로(15)에 압착슬리브(16)에 의해 시공되어 있다. 기존선로(15)는 인류애자(17)에 감겨져 있으며 바인드로 묶여져 있다. 압착슬리브(16)가 시공된 기존선로 부위는 압착에 의해 유연성이 떨어져 있으며 장력을 받기 때문에 경계부위에서 전선이 단절될 수 있는 여지가 있다. 그리고 기존선로(15) 보다 굵은 신설선로(18)를 연장해 갈 경우 지금은 대부분 기존선로(15)에 압착슬리브(16)를 사용하여 연결한다. 그러면 기존선로(15)의 일부분에 과부하구간(19)이 발생한다. 그렇지 않으면 기존선로(15)를 신설선로(18)의 동등이상의 규격의 전선으로 교체해야 하는 불합리한 일이 벌어진다.     1 is a diagram illustrating a connection error of a secondary column transformer in a conventional column transformer. In the columnar transformer 11 installed in the electric pole 12, the voltage lowering line 13 and the ground lowering line 14 are drawn out and are constructed by the crimping sleeve 16 on the lower existing line 15. Existing track 15 is wound on the human insulator 17 and tied to the bind. Existing line portion in which the crimping sleeve 16 is constructed is inflexible by the crimping and there is room for the wire to be disconnected at the boundary because it is subjected to tension. And when extending the new line 18 thicker than the existing line (15) is now mostly connected to the existing line 15 using the crimping sleeve (16). Then, an overload section 19 occurs in a portion of the existing line 15. Otherwise, there is an unreasonable task of having to replace the existing line 15 with a wire of standard or higher than that of the new line 18.

도 2는 본 발명의 배전선로 저압모선을 변압기에 적용한 사례도이다. 주상변압기(11)로부터 인출되는 전압인하선(13)과 접지인하선(14) 끝에 모선(21)을 연결부(22)를 통하여 연결시킨다. 연결부(22)는 압착하는 통형구조로 하는 것이 바람직하다. 연결부(22)가 원기둥 형태의 도체나 전선인 경우에 따라서는 분기슬리브를 사용하여 연결할 수도 있다. 모선(21)은 기존선로(15)에 모선지지밴드(23)로 결합 시켜 매달도록 하였다. 기존전선(15)이 모선(21)의 조가선 역할을 한다. 이 경우 기존전선(15)과 모선(21)간 열발산이 잘 되도록 간격을 적당히 유지하도록 한다. 모선지지밴드(23)로 바인드전선(미도시)을 활용하여 모선이 유동하지 않도록 할 수도 있다. 또한 모선(21)은 전주에 별도의 애자를 사용한 설치금구류를 통하여 전주부착 형태로 설치할 수도 있다(미도시). 기존선로(15)와 신설선로(18)가 인류애자(17)에 감겨진 후 장력이 없는 전선 끝 부위가 모선(21)과 분기슬리브(16)를 통해 결합된다. 이렇게 되면 도1에서와 같은 기존선로(15)의 장력이 받는 장소에 분기슬리브(16)가 시공되는 일도 없으며 신설선로(18)는 자신의 굵기보다 굵은 모선(21)에 연결됨으로써 과부하구간(19)을 발생시키지도 않는다. 본 발명은 주상변압기 인하선의 선로에 연결, 기설선로에 신설선로 연결, 인입선의 배전선로에 연결 등에 다양하게 활용할 수 있다.     Figure 2 is a case of applying the low-voltage busbar distribution line of the present invention to the transformer. The bus line 21 is connected to the end of the voltage lowering line 13 and the ground lowering line 14 drawn from the columnar transformer 11 through the connection part 22. It is preferable to make the connection part 22 into a cylindrical structure which crimps | compresses. Depending on the case where the connecting portion 22 is a cylindrical conductor or wire, it may be connected using a branch sleeve. The bus bar 21 was coupled to the bus line support band 23 to the existing line 15 to be suspended. Existing wire (15) serves as a concave line of the mother bus (21). In this case, the interval is properly maintained so that heat dissipation between the existing wire 15 and the bus line 21 is good. By using a bind wire (not shown) as the busbar support band 23, the busbar may not flow. In addition, the mother bus 21 may be installed in a pole attached form through the mounting bracket using a separate insulator on the pole (not shown). After the existing line 15 and the new line 18 are wound on the human insulator 17, the end portion of the wire without tension is coupled through the bus line 21 and the branch sleeve 16. In this case, the branch sleeve 16 is not constructed at the place where the tension of the existing line 15 is received as shown in FIG. 1, and the new line 18 is connected to the busbar 21 that is thicker than its own thickness, thereby overloading the section 19. It does not generate). The present invention can be used in various ways, such as connecting to the line of the column transformer transformer line, connecting the new line to the existing line, connection to the distribution line of the incoming line.

And if a further branch line is needed in the future, the new crimping extension bus 60 is expanded by combining the extension conductor 62 and the branch line 42 of the existing crimping expansion bus 60 at the branch sleeve 61. The expansion conductor 62 serves as the main line 31 in the new crimping expansion bus 60. In this case, the utilization of the material is very good.
