본 고안은 고압의 전원을 차단, 접속시키는 가스개폐기에 사용되는 부싱(Bushing)에 관한 것으로, 특히 기존의 복잡한 애자설치작업이 필요없이 사용될수 있는 합성수지 몰딩물로 구성되는 가스개폐기 부착용 접속부싱과 케이블 접속부싱의 결합구성으로 이루어져서 간편한 설치작업과 강한 내트래킹(tracking)성을 갖도록 하여 사용 수명의 최대화가 제공되는 가스개폐기용 부싱(Bushing)에 관한 것이다.The present invention relates to a bushing (bushing) used in the gas switch for disconnecting and connecting the high-voltage power supply, and in particular, a gas bushing attachment connecting bushing and cable consisting of a synthetic resin molding that can be used without the need for existing insulator installation work A bushing for a gas switchgear provided with a combined configuration of a connection bushing to have a simple installation work and a strong tracking resistance, thereby providing a maximum service life.
일반적으로 종래의 가스개폐기에 케이블의 연결접속은 제1도및 제2도에 도시된 바와같이, 상기 가스개폐기(100)에 접속구성되는 자기재의 애자(101)를 설치하고 상기 애자(101)에 케이블(104)이 접속되어 일체로 성형된 몰드콘(200)을 연결접속하는 방식을 채택하여 왔다.In general, the connection of the cable to the conventional gas switch is installed in the insulator 101 by installing the insulator 101 of the magnetic material connected to the gas switch 100, as shown in FIG. The cable 104 has been adopted to connect and connect the molded mold 200 formed integrally.
그러나 이러한 종래의 방식은 항상 애자(101)의 사용에 의한 기기설비의 설치비용의 증가용인으로 지적되었다.However, such a conventional method has always been pointed out as an increase in the installation cost of the equipment by the use of the insulator 101.
특히, 이러한 애자(101)는 충격에 깨지기 쉬운 자기제로 이루어지는바, 비래물(飛來物)이 충돌하던지, 표면의 오손에 의한 외부섬락(外部閃絡)이 생기든지, 부싱내부에서 절연파괴가 발생되었을 경우에는 애자(101)가 파괴되어 충전되어 있는 고압력의 절연성가스의 순간적인 방출사고가 발생되고, 이러한 파괴된 애자(101)의 파편이 주위에 비산되어서 주위에 있는 기기나 설비에 충돌되어 파괴되는 안전성이 문제점이 대두되고 있는 실정이다.In particular, the insulator 101 is made of a magnetic material that is fragile to impact, such as collision of flying objects, external flashover due to surface contamination, or insulation breakdown inside the bushing. When it occurs, the insulator 101 is destroyed and an instantaneous release of high-pressure insulating gas is generated, and fragments of the broken insulator 101 are scattered around and collide with surrounding equipment or equipment. Destructive safety is a problem that is emerging.
본 고안은 상기와 같은 종래기술이 갖는 제문제점을 해소하고자 창출된 것으로, 본 고안의 주목적은 가스개폐기에 케이블을 연결접속시킴에 있어 애자의 설치구성이 필요없이 강한 내트래킹성을 갖는 합성수지몰딩물로 구성되는 가스개폐기 부착용 접속부싱과 케이블 접속부싱의 결합구성에 의한 간편한 설치작업과 외부의 충격에 강한 내트래킹성을 갖는 합성수지몰드물로서 사용수명의 최대화가 제공되는 가스개폐기용 부싱을 제공하는데 있다.The present invention was created to solve the problems of the prior art as described above, the main purpose of the present invention is a synthetic resin molding having a strong tracking resistance without the need for the insulator installation in connecting the cable to the gas switch It is a synthetic resin molding having a simple installation work and a tracking resistance against external shocks by a combination of a gas bushing attachment connecting bushing and a cable connecting bushing, and to provide a bushing for a gas opener that provides a maximum service life. .
본 고안의 다른 목적은 외부가 합성수지재로 구성되어서 외부충격에 견딜수 있어 설치의 견고성이 제공되고, 표면오손의 방지가 제공되어서 외부섬락(外部閃絡)이 전혀 없는 가스개폐기용 부싱을 제공하는데 있다.Another object of the present invention is to provide a bushing for a gas switchgear that is made of a synthetic resin material to withstand external shocks and is provided with robustness of installation, and is provided with prevention of surface contamination, thereby providing no external flashover. .
본 고안의 또 다른 목적은 가스개폐부착용 접속부싱과 케이블 접속부싱의 연결접촉부에서 발생되는 전계집중현상을 방지하는 독특한 구조를 채택하여서 부싱내부에서 절연파괴가 전혀없는 가스개폐기용 부싱을 제공하는데 있다.Another object of the present invention is to provide a gas switchgear bushing that has no breakdown inside the bushing by adopting a unique structure that prevents electric field concentration phenomenon occurring at the connection contact portion of the gas opening and closing attachment bushing and the cable connection bushing.
이하, 첨부된 도면에 의거하여 본 고안의 구성을 상세히 살펴보면 다음과 같다.Hereinafter, the configuration of the present invention based on the accompanying drawings in detail.
즉, 첨부된 도면 제3도 및 제4도에 도시된 바와같이 케이블(1)의 선단나선부(11)와 맞물림결합되는 도체봉(2)의 외부면에 케이블(1)측으로 부터 넓어지는 테이퍼형 둘레면을 가지는 수지몰드물(3)으로 구성되는 것에 있어서, 상기 수지몰드물(3)은 내부에 단차진 테이퍼형 결함홈부(4)를 형성하고 상기 도체봉(2)의 선단에 형성되는 결합볼트공(5)이 돌출되어서 일체로 성형되되, 상기 결합홈부(4)의 내측끝단에는 도전성고무링(6)이 내착되어서 상기 도체봉(2)과 접속되어서 일체로 성형되어 구성되는 케이블 접속부싱(10)과 상기 결합홈부(4)에 상응된 형태의 결합돌부(13)을 형성한 수지몰드물(12)의 내부에 선단으로 결합너트홈(15)을 갖는 도체봉(14)이 구성되고 외측으로 지지링(16)이 돌출되어서 일체로 성형되는 가스 개폐기 부착용 접속부싱(20)으로 구성된다.That is, the taper is widened from the cable 1 side to the outer surface of the conductor rod (2) meshed with the distal end portion 11 of the cable (1) as shown in FIGS. In the resin molding 3 having a mold circumferential surface, the resin molding 3 forms a stepped tapered defect groove 4 therein and is formed at the tip of the conductor rod 2. The coupling bolt hole (5) protrudes to be integrally formed, and the inner end of the coupling groove (4) has a conductive rubber ring (6) internally connected to the conductor rod (2) is formed integrally molded cable connection A conductive rod 14 having a coupling nut groove 15 at its tip is formed inside the resin molding 12 having the bushing 10 and the coupling protrusion 13 having a shape corresponding to the coupling groove 4. And a support ring 16 for protruding outwardly and integrally molded to form a gas switch attachment connecting bushing 20.
이와같이 구성된 본 고안은 가스개폐기(100)에 통상의 방식으로 가스개폐기 부착용 접속부싱(20)을 지지링(16)을 통하여 부착고정시킨 상태에서 수지몰드물(12)의 결합돌부(13)에 상기 케이블 접속부싱(10)의 결합홈부(4)를 끼운상태에서 각각의 내부에 구성된 도체봉(2)(14)의 결합볼트봉(5) 및 결합 너트홈(15)에 의한 상호 나사결합으로 간단하게 설치작업이 제공된다.The present invention configured as described above is connected to the coupling protrusion 13 of the resin molding 12 in a state in which the gas bushing attachment connecting bushing 20 is attached and fixed through the support ring 16 in a conventional manner. In the state where the coupling groove part 4 of the cable connection bushing 10 is inserted, it is simple by mutual screwing by the coupling bolt rod 5 and the coupling nut groove 15 of the conductor rods 2 and 14 which are formed inside, respectively. Installation is provided.
이때 상기 가스개폐기 부착용 접속부싱(20)의 도체봉(14)에 의한 가스개폐기(100)에서 발생되는 고압의 전원이 상기 케이블 접속부싱(10)의 도체봉(2)를 통하여 케이블(1)를 흐를때 상기한 도체봉(2)(14)의 접촉부에서 전계집중 현상을 상기 결합홈부(4)에 내착되면서 도체봉(2)에 접속구성된 도전성고무링(6)에 의하여 방지되어서 내부의 절연파괴가 없이 용이하게 전원이 흐르게 되는 것이다.At this time, the high-voltage power generated by the gas switch 100 by the conductor rod 14 of the connection bushing 20 for attaching the gas switch is connected to the cable 1 through the conductor rod 2 of the cable connection bushing 10. When flowing, the electric field concentration phenomenon is prevented by the conductive rubber ring 6 connected to the conductive rod 2 while the electric field concentration phenomenon is embedded in the coupling groove 4 at the contact portion of the conductive rods 2 and 14. Power will flow easily without
이와같은 본 고안에 의하면 기존의 애자(101)의 설치에 따른 설치비용을 없애고, 외부의 충격에도 강한 합성수지 몰드물로 구성되어서 기기의 안전성이 제공되며, 부싱간의 연결접촉부에서의 전계집중을 방지할 수 있는 독특한 구조를 채택하여서 기기수명의 연장이 제공되는 등 매우 유용한 고안임이 명백한 것이다.According to the present invention, the installation cost according to the existing insulator 101 is eliminated, and the safety of the device is provided by being made of a synthetic resin mold that is also resistant to external impact, and prevents electric field concentration at the connection contact between the bushings. It is obvious that this is a very useful design, such as the long life of the device is provided by adopting a unique structure.
