본 발명은 라인포스트 애자의 점퍼선 보호장치에 관한 것으로, 더욱 상세하게는 점퍼선을 항상 긴장된 상태로 유지시킴으로써 라인포스트 애자에 가설되는 점퍼선의 손상을 방지하고, 송배전 전선케이블의 수명을 연장시킴과 더불어 설비사고를 미연에 방지할 수 있는 라인포스트 애자의 점퍼선 보호장치에 관한 것이다.
The present invention relates to a jumper wire protection device of the line post insulator, and more particularly, to prevent the damage of the jumper wires installed on the line post insulator by extending the jumper wire at all times and to extend the life of the transmission and distribution wire cable. In addition, the present invention relates to a jumper wire protection device for line post insulators that can prevent equipment accidents in advance.

일반적으로, 발전소에 발생되는 대전력은 송전탑 등의 송전선로를 통해 고압의 전력으로 각 변전소로 송전된 다음, 변전소에서는 여러 단계의 변압과정을 거쳐 각 가정 또는 건물 등의 수용가에서 사용할 수 있도록 케이블을 이용하여 각 지역으로 공급하게 되는 배전과정을 거치게 된다.In general, large power generated in a power plant is transmitted to each substation with high voltage power through a transmission line such as a transmission tower, and then, at a substation, the cable is used for the use in each home or building through a multi-stage transformation process. It goes through the distribution process to supply to each region.

이때, 일반 수용가에 대한 전력공급은 일정간격으로 설치되는 전신주를 통해 공급하고, 각 전신주에서의 송,배전 전선케이블의 연결은 점퍼선을 이용하여 연결하게 된다. 즉, 전신주에 연결하고자 하는 송,배전 전선케이블을 전신주 상단 양측에 횡으로 설치되는 완금의 양측에서 애자를 통해 결합하고, 상기 애자 사이를 점퍼선으로 연결하되, 연결되는 점퍼선은 완금의 상단에 설치되는 애자를 통해 지지될 수 있도록 시공하여 사용하였다.At this time, the power supply to the general consumer is supplied through the telephone poles installed at regular intervals, and the connection of the transmission and distribution wire cables in each telephone pole is connected using a jumper wire. That is, the transmission and distribution wire cable to be connected to the telephone poles are coupled through the insulators on both sides of the complete side installed on both sides of the top of the telephone poles, and the jumper wires are connected between the insulators, but the jumper wires connected to the upper ends of the complete poles. It was used to construct so that it can be supported through the insulator to be installed.

또한, 라인포스트 애자(LP insulator)라 함은 전신주의 상부측에 완금과 같은 지지부재를 통해 설치된 상태에서 송배전선로를 절연하는 애자로서, 이러한 라인포스트 애자는 그 몸체 상부측에 송배전 전선케이블과 대지를 절연하기 위한 수단으로 고정와이어를 통해 점퍼선이 수평방향으로 고정되어 있다. 즉, 송배전 전선케이블에는 전신주(1)의 몸체 상부측에 수평방향으로 장착된 완금(2)과, 이 완금(2)의 상부측 또는 하부측에 다수개의 라인포스트 애자(3)가 장착되고, 라인포스트 애자(3)의 상부측에 송배전 전선케이블과 대지를 절연하는 점퍼선(4)이 고정되어 있다.In addition, the line post insulator (LP insulator) is an insulator that insulates the transmission and distribution line in the state of being installed on the upper side of the telephone pole through a support member, such as a complete, such a line post insulator on the upper side of the body The jumper wire is fixed in the horizontal direction through the fixing wire as a means to insulate the wires. That is, the transmission and distribution wire cable is equipped with a loom 2 mounted in the horizontal direction on the upper body side of the telephone pole 1, and a plurality of line post insulators 3 on the upper side or the lower side of the loom 2, The jumper wire 4 which insulates a transmission-distribution electric wire cable and a ground is fixed to the upper side of the line post insulator 3. As shown in FIG.

라인포스트 애자(3)와 점퍼선(4)의 고정구조를 구체적으로 설명하면, 라인포스트 애자(3)의 몸체상단부에 안착구(5)가 일체로 형성되고, 이 애자안착구(5)의 상부면에 형성된 안착홈(5a)에 점퍼선(4)이 고정와이어(6)에 의해 고정되어 유동이 방지되도록 고정되는 것이다.
When the fixing structure of the line post insulator 3 and the jumper wire 4 is demonstrated concretely, the seating opening 5 is integrally formed in the upper end of the body of the line post insulator 3, and the The jumper wires 4 are fixed to the seating grooves 5a formed on the upper surface by the fixing wires 6 so that the flow is prevented.

그러나, 종래 기술에 의한 라인포스트 애자에 따르면 다음과 같은 문제점이 있다.However, the line post insulator according to the prior art has the following problems.

점퍼선(4)이 어떠한 지지수단 및 보호수단이 없이 라인포스트 애자(3)와 송,배전 전선케이블 사이에 설치됨으로써, 장기간 사용도중 풍압에 의해 점퍼선(4)이 늘어지거나, 전신주와의 접촉 등의 이유로 인해 점퍼선(4)의 피복을 손상시키거나 또는 점퍼선(4)의 전자기력에 의해 점퍼선의 피복이 손상되는 현상이 발생하였으며, 이 경우 점퍼선(4)의 단선과 같은 설비사고가 발생하게 되어 송배전 전선케이블의 수명을 단축시키게 됨은 물론, 안정적인 전력공급을 할 수 없게 되는 문제점이 있었다.
Since the jumper wire 4 is installed between the line post insulator 3 and the transmission and distribution wire cable without any supporting means or protection means, the jumper wire 4 is stretched due to wind pressure during long-term use, or contact with the telephone pole. For example, the coating of the jumper wire 4 may be damaged or the coating of the jumper wire may be damaged by the electromagnetic force of the jumper wire 4. In this case, an equipment accident such as disconnection of the jumper wire 4 may occur.

점퍼선 배선블록(40)의 상면에는 제2가이드장공(44a)이 구비된 한 쌍의 지지벽(44)이 세워지며, 지지벽(44)의 제2가이드장공(44a)과 높이조정블록(60)의 제1가이드장공(62)에는 지지핀(45)이 관통 설치된다. 지지핀(45)은 볼트와 너트일 수도 있고, 양측이 벤딩되는 핀일 수도 있다.On the upper surface of the jumper wire wiring block 40, a pair of supporting walls 44 are provided with the second guide holes 44a, and the second guide holes 44a of the support walls 44 and the height adjusting blocks ( The support pin 45 is penetrated through the first guide slot 62 of 60. The support pins 45 may be bolts and nuts, or pins at both sides thereof may be bent.

본 발명에 의한 라인포스트 애자의 점퍼선 보호장치의 작용은 다음과 같다.The action of the jumper wire protection device of the line post insulator according to the present invention is as follows.

점퍼선(4)의 설치시 높이조정볼트(10)를 통해 애자(3)의 높이를 1차로 설정한다. 즉, 높이조정볼트(10)를 예를 들어 시계방향으로 돌리면 높이조정볼트(10)가 체결되면서 애자(3)를 상승시키며, 애자(3)의 상승에 의해 점퍼선 고정구(5)가 상승함에 따라 점퍼선(4)이 팽팽하게 긴장된다. 이와 같이 높이조정볼트(10)로 점퍼선(4)을 1차로 긴장시킨 후, 높이조정수단을 통해 점퍼선(4)의 텐션을 다음과 같이 미세 조정한다.When the jumper wire 4 is installed, the height of the insulator 3 is set to primary through the height adjusting bolt 10. That is, when the height adjustment bolt 10 is turned clockwise, for example, the height adjustment bolt 10 is fastened while the insulator 3 is raised, and the jumper wire fixture 5 is raised by the rise of the insulator 3. As a result, the jumper wires 4 are tensioned. As such, after the jumper wires 4 are primarily tensioned by the height adjustment bolts 10, the tension of the jumper wires 4 is finely adjusted through the height adjustment means as follows.

높이조정구(80)를 예를 들어 시계방향으로 돌리면 높이조정구(80)가 체결되면서 슬라이더(70)를 전진시키며, 슬라이더(70)의 전진은 제1,2경사부(41,71)에 의해 높이조정블록(60)의 상승운동으로 전환되어 높이조정블록(60)이 서서히 상승한다.For example, when the height adjusting device 80 is turned clockwise, the height adjusting device 80 is fastened to move the slider 70, and the advancement of the slider 70 is performed by the first and second inclined parts 41 and 71. Switched to the upward movement of the adjustment block 60, the height adjustment block 60 is gradually raised.

따라서, 점퍼선 고정구(4)가 상승하여 긴장력이 더 커지게 되며, 점퍼선(4)이 정상적인 긴장력으로 설정되면 높이조정작업을 완료한다.Therefore, the jumper wire fixture 4 rises to increase the tension force, and when the jumper wire 4 is set to the normal tension force, the height adjustment work is completed.

또한, 상기 높이조정수단을 통해 점퍼선(4)의 2차 텐션 조정이 완료된 후, 점퍼선(4)의 텐션 조정이 필요한 경우 점퍼선 고정구(50)를 돌리면, 배선링(51)의 각도가 변하게 되어 점퍼선(4)이 꼬이게 됨으로써 점퍼선(4)이 더욱 팽팽해진다.
Further, after the secondary tension adjustment of the jumper wire 4 is completed through the height adjusting means, when the tension of the jumper wire 4 is required, the jumper wire fixture 50 is turned, and the angle of the wiring ring 51 is increased. As the jumper wires 4 are twisted, the jumper wires 4 are further tightened.
