Description

컷아웃스위치 완철 절연 커버{Insulated cover for steel crossarm of COS supporting}Cutout Switch Wrought Iron Insulation Cover {Insulated cover for steel crossarm of COS supporting}

본 발명은 컷아웃스위치(이하, COS라 칭함) 완철 절연 커버에 관한 것이다.더욱 상세하게는, 배전 설비의 유지 관리가 용이하고, COS를 취부하기 위한 시공 상에 편리함은 물론 결합애자 파손 등으로 선로 고장 및 안전 사고의 위해 요인도 제거할 수 있는 COS의 지지 부재가 체결될 수 있는 완철 부위를 전체적으로 감쌀 수 있는 구조로 이루어진 COS 완철 절연 커버에 관한 것이다.The present invention relates to a cut-out switch (hereinafter referred to as COS) wrought iron insulated cover. More specifically, it is easy to maintain and maintain a power distribution facility, and is convenient for construction for mounting COS, as well as damage to coupling insulators. The present invention relates to a COS-wrought iron insulated cover, which has a structure that can completely cover a wrought iron part to which the support member of the COS, which can also remove the hazards of line failure and safety accident, can be fastened.

일반적으로 COS는 주상 변압기의 1차측에 부착하여 과전류로부터 변압기기를 보호하고 가스 방출에 의한 개방형으로 개폐상태를 쉽게 확인할 수 있는 것으로 이러한 COS를 전주의 완철에 직접 취부할 경우에는 대지간의 절연 미달로 인하여 COS 개폐기 조작시 발생되는 섬락 현상의 발생 등으로 기기 파손과 선로 고장을 유발하게 된다.In general, the COS is attached to the primary side of the column transformer to protect the transformer from overcurrent and can be easily opened and closed due to gas discharge. The flashover phenomenon that occurs when operating the COS switch causes equipment damage and line failure.

또한, 염진해 부착 등으로 절연 레벨이 저하되고, 누설 전류에 의한 안전 사고와 지락 고장을 유발하게 된다.In addition, the insulation level is lowered due to salty adhesion and the like, which causes a safety accident and ground fault due to leakage current.

이에 따라 최근에는 전주의 완철에 기계적으로 고정시키고 전기적으로 절연시키기 위하여 절연 보강재인 애자(insulator)를 많이 사용하고 있다.Accordingly, in recent years, insulators (insulators), which are insulation reinforcing materials, have been used in order to mechanically fix and electrically insulate steel poles.

즉, 종래에는 첨부 도면 중 도 2에 나타낸 바와 같이 완철(21)에 COS(22)를 지지해 주기 위한 지지 부재(23) 상에다 COS(22)와 대지간 절연 보강재로서 네오손 결합 애자 또는 폴리머 내오손 결합 애자(24)를 취부하거나, 도 3에 나타낸 바와 같이 완철(31)에 COS(32)를 지지해 주기 위한 지지 부재(33) 상에다 COS(32)와 대지간 절연 보강재로서 크레비스 현수 애자(34)를 취부하여 왔다.That is, in the past, as shown in FIG. 2 of the accompanying drawings, on the support member 23 for supporting the COS 22 on the cast iron 21, the neoson bonding insulator or polymer as the insulation reinforcing material between the COS 22 and the earth. Creos suspending as an insulation reinforcing material between the COS 32 and the ground on the support member 33 for attaching the anti-fouling insulator 24 or supporting the COS 32 to the finished steel 31 as shown in FIG. 3. The insulator 34 has been mounted.

그러나, 완철에 절연 보강재를 추가하여 COS를 취부할 경우에는 절연 보강재 설비를 추가로 해야 하므로 이에 따른 공사 원가 증대의 부담이 있고, 장주가 복잡하게 될 뿐 아니라 불량 보강 기자재의 파손 등으로 인하여 안전 사고는 물론 선로 고장을 유발하는 등의 문제가 있었다.However, when COS is installed by adding insulation reinforcement to the finished steel, additional insulation reinforcement equipment must be added, which increases the cost of construction work, complicates the market, and causes safety accidents due to damage of defective reinforcement equipment. Of course there was a problem such as causing a line failure.

이에 따라 최근에는 COS 자체를 절연 보강시키는 연구가 있었으나, 절연 보강에 따른 규격 및 기술 개발에 비용이 과다하게 소요됨에 따라 연구가 지지부진한 상태에 있다.Accordingly, there has been a recent study to insulate the COS itself, but the research is in poor condition due to the excessive cost for the development of the specifications and technology according to the insulation reinforcement.

이에 본 발명은 상술한 종래의 문제점을 해결하기 위하여 발명한 것으로서, 종래에 결합 애자 대신에, COS가 취부되는 지지 부재가 체결되는 완철 부위에 절연 커버를 부착하게 되면, 배전 설비의 유지 관리가 용이하고, COS를 취부하기 위한 시공 상에 편리함은 물론 결합 애자 파손 등으로 선로 고장 및 안전 사고의 위해 요인도 제거할 수 있음을 알게 되어 본 발명을 완성하게 되었다.Accordingly, the present invention has been invented to solve the above-mentioned conventional problems, and in place of the coupling insulator, when the insulation cover is attached to the finished part to which the support member to which the COS is mounted is fastened, maintenance of the power distribution equipment is easy. In addition, the present invention has been completed by finding that it is possible to remove the hazards of the line failure and the safety accident due to the damage of the coupling insulator, etc., as well as the convenience in construction for mounting the COS.

즉, 본 발명은 COS의 지지 부재가 체결될 수 있는 완철 부위를 전체적으로 감쌀 수 있는 구조로 이루어진 COS 완철 절연 커버를 제공하는데 그 목적이 있는 것이다.That is, an object of the present invention is to provide a COS wrought iron insulating cover made of a structure that can entirely wrap the wrought iron portion to which the support member of the COS can be fastened.

도 1a는 본 발명에 따른 컷아웃스위치(COS) 절연 커버의 사시도 이다.1A is a perspective view of a cutout switch (COS) insulating cover according to the present invention.

도 1b는 본 발명에 따른 절연커버를 부착한 완철에 직접 컷아웃스위치(COS)를 지지한 상태를 보여주기 위한 사용 상태 사시도 이다.1B is a perspective view illustrating a state in which a cutout switch (COS) is directly supported on a wrought iron with an insulation cover according to the present invention.
