Description
본 고안은 22.9㎸ 가공 배전선로의 전선가선 작업시 연선작업을 용이하게 하면서 전선단선고장의 최소화가 이루어지는 개선된 연선롤라 부착형 완금에 관한 것이다.The present invention relates to an improved twisted pair roller-attached mold that minimizes the breakdown of wires while facilitating twisted wires during wire twisting of 22.9㎸ overhead distribution lines.
일반적으로 22.9㎸ 가공 배전선로의 가선작업을 수행하기 위한 연선작업시 연선롤라를 이용하여 작업을 수행하는바, 기존 연선롤라는 무게가 무겁고 부피가 커서 휴대 및 설치작업이 번거로워 연선작업시 이 연선롤라를 이용하지 않고, 특고압선을 지면에서 차량 또는 인력을 이용하여 연선함에 따라 자연히 전선피복의 손상이 발생할 뿐만 아니라, 전선 비틀림 현상이 야기되는 등 전선단선의 원인을 제공하는 문제점이 있었다.Generally, stranded rollers are used to perform the wire work of 22.9㎸ overhead distribution line. Conventional stranded rollers are heavy and bulky, which makes them difficult to carry and install. There is a problem of providing the cause of wire breakage, such as not only the damage of the wire coating, but also the twisting of the wire as a special high-voltage line is twisted by using a vehicle or manpower from the ground.
이러한 절연전선의 단선고장 원인을 좀더 구체적으로 살펴보면, 절연전선은 서어지 전압에 의해 절연내력을 초과하면, 섬락이 발생하고 핀홀(pinhole)이 생성되며, 이때 절연 내력은 저하되고 낮은 전압에서도 동일개소에 섬락이 누적되므로 결국 아크열에 의해 이 절연전선이 용단되고, 그리고 지지애자 부근에서 전선피복이 손상되면 오손 및 수분 침투가 용이하여 트래킹(tracking)에 취약하여 절연전선의 용단이 손쉽게 이루어진다.Looking at the cause of the breakdown failure of the insulated wire in more detail, if the insulated wire exceeds the insulation strength by the surge voltage, flashover occurs and pinholes are generated, the insulation strength is lowered, even at low voltage Since flashovers accumulate at the end, this insulated wire is melted by arc heat, and when the wire coating is damaged near the support insulator, fouling and moisture infiltration are easy, and the insulation wire is easily vulnerable to tracking.
또한 피복이 손상되면 오손에 취약함에 따라 손상부위는 저항의 증가로 국부적 발열을 유발함으로서 아크발생시 주위 절연체는 열의 흐름에 방해를 받아 나전선에 비하여 빠른 시간에 전선 용단에 이르게 된다.In addition, if the sheath is damaged, the damaged part causes local heat generation due to the increase of resistance, so that when the arc is generated, the surrounding insulator is interrupted by the flow of heat, leading to wire melting at a faster time than the bare wire.
따라서 연선 작업시 전선피복에 손상을 입히지 않고 용이하게 작업을 해야 전선단선고장을 해소화할 수 있는 것이다.Therefore, when working with stranded wires, it is possible to solve the breakage of the wire break only when the work is done easily without damaging the wire coating.
이에 본 고안은 상기와 같은 종래 문제점을 감안하여 안출된 것으로, 연선작업시 전선피복을 손상시키지 않고 휴대 및 설치 작업이 용이한 개선된 연선롤라 부착형 완금을 제공함에 그 목적이 있다.Accordingly, the present invention has been made in view of the above-described conventional problems, and an object thereof is to provide an improved twisted pair roller-attached mold that is easy to carry and install without damaging the wire coating during twisting.
상기 같은 목적을 달성하기 위한 본 고안은 완금본체에 지지롤러들이 구비된 지지대를 일체로 부착시키고 이 지지대의 내부에 설치되는 회동이 자유로운 지지롤러들 사이로 전선이 통과하는 구조로 되어 있다.The present invention for achieving the above object is a structure in which the wire is passed between the support rollers are freely attached to the support body provided with the support rollers and the rotatable support rollers installed in the support body.
도 1은 본 고안에 따른 연선롤라 부착형 완금을 나타낸 구성도이다.1 is a block diagram showing the twisted roller attached to the complete according to the present invention.

도 1은 본 고안에 따른 연선롤라 부착형 완금을 나타낸 도면으로서, 본 고안은 완금본체(1)에 지지롤러(2a, 2b)들이 구비된 지지대(3)를 일체로 부착시키고 이 지지대(3)의 내부에 설치되는 회동이 자유로운 지지롤러(2a, 2b)들 사이로 전선(4)들이 통과하는 구조로 되어 있다.1 is a view showing a stranded roller attached complete according to the present invention, the present invention is integrally attached to the support (3) equipped with support rollers (2a, 2b) to the complete body (1) and this support (3) The electric wires 4 pass between the freely rotatable support rollers 2a and 2b which are installed in the inner side of the roller.
여기서 상기 지지롤러(2a, 2b)들 사이로 통과하는 전선(4)의 가닥은 약 3개이나 필요에 따라 증감하여 연선 작업을 할 수 있다.Here, about 3 strands of the wire 4 passing between the support rollers 2a and 2b may be increased or decreased as necessary to perform the stranded wire work.
그리고 이 지지롤러(2a, 2b)들은 고강도 합성수지 재질로 되어 있으며, 지지대(3)는 완금본체(1)와 동일재질로 되어 있다.The support rollers 2a and 2b are made of a high strength synthetic resin material, and the support 3 is made of the same material as the body 1.
이같이 본 고안은 완금본체(1)에 연선작업용 지지롤러(2a, 2b)를 부착함에 따라 연선 작업시 전선가선의 편의성과 전선피복의 손상을 방지하여 전선단선의 고장을 예방하게 된다.As such, the present invention prevents the breakage of the wire by preventing the convenience of the wire and the damage of the wire coating during the twisted wire work by attaching the supporting rollers 2a and 2b for the twisted wire work to the complete body 1.
