It relates to a compression type heterometal branched rib to prevent the.
일반적으로 배전선로상에 설치되는 전주에는 주상변압기와 애자 및 컷아웃스위치등이 장착되어 있으며, 특고압전선을 통해 배전되는 전력은 컷아웃스위치를 거쳐 주상변압기로 제공되고, 주상변압기는 특고압으로 배전되는 전력을 사용가능한 정격전압(220볼트 내지 380볼트)으로 낮추어 단상 또는 3상 전력으로 가정이나 산업 체등에 공급하게 된다.Generally, pole pole transformer, insulator and cut-out switch are installed on electric pole installed on distribution line, and power distributed through extra-high voltage line is provided to column pole transformer through cut-out switch. The power to be distributed is lowered to the usable rated voltage (220 volts to 380 volts) to be supplied to homes or industries as single-phase or three-phase power.
기존 주상변압기의 설치형태는 도면에 도시된 도 1과 같이 전주(1)에 설치된 고압전선(2)으로부터 컷아웃스위치(3)로 전력이 제공되고, 컷아웃스위치(3)에서 전주(1)에 고정 설치된 주상변압기(4)로 전력이 공급되며, 주상변압기(4)를 통해 변압된 전력은 1차 인하선(4a)에 의해 전력선(5)으로 제공되어 정격 전압을 송전하게 되고, 한편 주상변압기(4)의 또다른 2차 인하선(4b)은 전주(1)에 가설된 특고압 중성선(6)에 접속되는 구조를 갖추고 있다.In the installation form of the existing columnar transformer, power is supplied from the high voltage wire 2 installed in the pole 1 to the cutout switch 3, as shown in FIG. 1, and the pole 1 of the cutout switch 3. Power is supplied to the columnar transformer (4) fixed to the power supply, the power transformed through the columnar transformer (4) is provided to the power line (5) by the primary cut-off line (4a) to transmit the rated voltage, while Another secondary lowering line 4b of the transformer 4 has a structure that is connected to the extra-high voltage neutral wire 6 installed on the pole 1.
상기에서 주상변압기의 2차 인하선과 전주에 가설된 특고압 중성선의 접속방식은 도면의 도 2와 도3과 같이 알루미늄 재질로 형성된 분기스리브(10)를 이용하여 두가닥의 전선을 접속하게 되며, 일반적으로 분기스리브(10)에 형성된 상하접속홀(11)(lla)에 특고압중성선(6)과 주상변압기의 인하선(4b)을 끼우고, 압축기(도시하지 않음)로 분기스리브(10)의 외부를 압착하여 두선의 접속이 이루어진다.In the above connection method of the secondary lowering line of the columnar transformer and the extra-high voltage neutral wire hypothesized on the pole, the two wires are connected by using the branch rib 10 formed of aluminum as shown in FIGS. In general, the high-pressure neutral line 6 and the lowering line 4b of the columnar transformer are inserted into the upper and lower connecting holes 11 and lla formed in the branch rib 10, and the branch rib 10 is formed by a compressor (not shown). The two wires are connected by crimping the outside.
기존 전주에 가설되는 특고압중성선은 여러 가닥이 나선으로 꼬여진 알루미늄선으로 있으며, 또한 주상변압기의 인하선은 여러 가닥이 나선으로 꼬인 동선으로 피복층이 코팅되어 있고, 분기스리브에 접속되는 부분의 피복층을 제거한 다음 접속이 이루어진다.The extra-high-voltage neutral wire hypothesized in the existing electric pole is made of aluminum wire twisted into several strands, and the lower wire of the column transformer is coated with a copper wire twisted into several strands and coated with a coating layer. Then remove the connection.
기존 특고압중성선과 주상변압기의 인하선을 연결 접속하는 방식은 나선으로 꼬여진 동선과 알루미늄선을 분기스리브의 접속홀에 끼우고 분기스리브를 압착시켜 접속하므로써 나선으로 꼬여 표면이 불규칙한 동선이 분기스리브의 접속홀에 완전 밀착되지 못하여 접촉면적이 적으며, 알루미늄 재질의 분기스리브와 동선이 서로 다른 재질로 동선의 접속부위에서 부식작용이 급속히 발생하는 문제점이 야기되고 있다.The connection method of the existing high voltage neutral wire and the lower wire of columnar transformer is connected by connecting spirally twisted copper wire and aluminum wire into the connection hole of the branch rib and crimping the branch rib to connect the spiral wire. The contact area of the copper wire is not completely in contact with the contact area, and the contact area of the aluminum material is different from the branch ribs and the copper wire, which causes a problem of rapid corrosion at the copper wire connection part.
상기 동선의 부식작용은 이질금속간의 접속부위에 수분이나 이물질이 물고 전류가 흐름으로 가속화되어 동선이 단선되는 설정이고, 동선의 단선은 주상변압기의 기능을 저하시켜 이상전압(과전압)을 발생시킴으로 사용중인 전기·전자제품등을 소손시키는 막대한 피해를 일으키고 있다.The corrosive action of copper wire is a setting where copper or wire is disconnected due to water or foreign matter in the connection part between dissimilar metals and the current is accelerated by the flow of copper wire, and the disconnection of copper wire is used by generating abnormal voltage (overvoltage) by degrading the function of the column transformer. It is causing enormous damage to burn out electric and electronic products.
따라서, 본 고안은 상기와 같은 문제점들을 해결하고자 안출된 것으로, 주상 변압기의 인하선인 동선이 접속되는 분기스리브의 접속홀에 동관을 끼워 설치하고, 상기 동관에 주상변압기의 동선을 끼우고 분기스리브를 압착시켜 접속하므로 동관이 동선과 분기스리브의 접속홀을 완전 밀착시켜 접촉면적을 크게 하고, 전기저항을 감소시켜 이질금속간의 부식을 현저히 줄임으로써 동선의 단선을 방지하는 것을 본 고안의 목적으로 하는 것이다.Therefore, the present invention has been devised to solve the above problems, the copper pipe is inserted into the connection hole of the branch rib to which the copper wire, which is the lowering line of the column transformer, is installed, the copper wire of the column transformer is inserted into the copper pipe and the branch rib is The purpose of the present invention is to prevent copper wire breakage by crimping and connecting copper pipes to the contact holes between copper wire and branch ribs to increase contact area, increase electrical resistance and significantly reduce corrosion between dissimilar metals. .

여기서, 본 고안은 주상변압기(4)의 인하선(4b)이 끼워져 접속되는 분기스리브(10)의 접속홀(lla)에 인하선(4b)의 재질과 동일한 재질을 가지는 동관(20)을 끼워 설치하는 것으로, 상기 동관(20)은 접속홀(lla)과 동일한 길이를 갖게 형성되고, 접속홀(lla)의 내경보다 작은 외경을 갖도록 형성하여 접속홀(lla)에 끼워질 수 있도록 하고, 어느 정도 억지끼움되어 끼워진 상태에서 쉽게 빠져나오지 않도록 형성함이 바람직하다.Here, the present invention fits the copper tube 20 having the same material as the material of the lower line (4b) in the connection hole (lla) of the branch rib 10 is connected to the lower line (4b) of the columnar transformer (4) By installing, the copper tube 20 is formed to have the same length as the connection hole (lla), formed to have an outer diameter smaller than the inner diameter of the connection hole (lla) to be fitted into the connection hole (lla), which It is preferable to form it so that it does not come out easily in the clamped state.
본 고안의 설치작업은 먼저 두선이 접속되는 부분의 피복층을 제거한 다음 분기스리브(10)의 상측부 접속홀(11)에 특고압중성선(6)을 끼우고, 피복층이 제거된 인하선(4b)의 끝부분을 분기스리브(10)의 하측부 접속홀(lla)에 설치된 동관 (20)에 끼운 다음 압축기로 분기스리브(10)의 외부를 압착하여 두선을 접속하게 된다.The installation work of the present invention first removes the coating layer of the part where the two wires are connected, and then inserts the extra high pressure neutral wire 6 into the upper connection hole 11 of the branch rib 10, and the lowering wire 4b from which the coating layer is removed. The end of is inserted into the copper tube 20 installed in the lower connection hole (lla) of the branch rib 10, and then compressed by pressing the outside of the branch rib 10 with a compressor to connect the two wires.
상기에서 인하선(4b)과 동일한 재질의 동관(20)을 분기스리브(10)의 접속홀(lla)에 끼워 인하선(4b)을 접속하므로 분기스리브(10)의 압착시 인하선(4b)과 동관(20)의 접촉면적을 크게하는 한편 동관(20)과 접속홀(lla)의 접촉면적을 크게 함으로써 전류의 흐름이 양호하고 인하선(4b)과 분기스리브(10)의 접속홀(lla)사이 에 인하선(4b)과 동일 한재질의 동관(20)이 위치하므로 이질금속간의 부식작용에 의한 인하선(4b)의 단선을 방지하게 되는 것이다.Since the lower line 4b is connected by inserting the copper tube 20 of the same material as the lower line 4b into the connection hole lla of the branch rib 10, the lower line 4b when the branch rib 10 is crimped. By increasing the contact area between the copper tube 20 and the contact area between the copper tube 20 and the connection hole lla, the current flows well, and the connection hole lla of the lower line 4b and the branch rib 10 is improved. Since the copper tube 20 of the same material as the lowering line (4b) is located between the will be to prevent the disconnection of the lowering line (4b) due to the corrosive action between dissimilar metals.
