Description
본 고안은 지상설치형 개폐기용 엘보 접속재에 관한 것으로서, 특히 간소한 구조에 의한 절연성능을 극대화시키면서 제조원가를 절감하고 부피의 축소 및 설치부재의 간소화에 의한 제품의 신뢰도 및 멀티램 접속방식에 의해 부싱과의 접속이 원터치로 이루어지게 하여 접속이 매우 간편하고 취급의 용이성을 극대화한 개폐기용 엘보 접속재에 관한 것이다.The present invention relates to the elbow connection material for the ground-mounted switchgear, in particular, to maximize the insulation performance by the simple structure, reduce the manufacturing cost, reduce the volume and simplify the installation member of the product by the reliability and multi-ram connection method It is related to the elbow connection material for the switchgear is made by the one-touch connection is very simple and maximize the ease of handling.
일반적으로 25.8kV 지상설치형 개폐기용 엘보접속재는 도 1에 도시된 바와 같이, 케이블수용부(110)와 부싱결합부(120)를 구비하여 L-형의 몸통부(100)로 형성되어 있다.In general, the elbow connecting material for a 25.8kV ground-mounted switch is formed of an L-shaped body portion 100 having a cable receiving portion 110 and a bushing coupling portion 120, as shown in FIG.
이러한 엘보접속재(100)는 천연고무나 합성고무(이피디엠)와 같은 절연물질로 절연몸통부(101)가 성형되고, 이 절연몸통부는 이피디엠과 같은 탄성중합물질의 반도체성 보호층(102)으로 감싸서 성형되고 있다.The elbow connecting member 100 is formed of an insulating body 101 made of an insulating material such as natural rubber or synthetic rubber (IPDM), and the insulating body is a semiconductor protective layer 102 of an elastomeric material such as EPDM. It is wrapped and molded.
그리고 상기 케이블수용부(110)에는 고압케이블(도시되지 않음)의 도선이 다이스와 같은 기구로 압착 연결된 케이블 연결구(130)가 끼움 조립되고, 상기 부싱결합부(120)에는 부싱(B)의 접속단자(B-1)와 접속되는 접속봉(140)이 조립되되, 상기 케이블 연결구(130)의 관통공(131)에 상기 부싱결합부(120)의 후면에 형성된 공구출입공(125)을 통하여 끼움되고, 이 플러그공에는 마감처리 및 절연확보를 위해 절연캡(150)를 조립하여 구성되었다.In addition, the cable receiving unit 110 is fitted with a cable connector 130 connected by crimping the conductor of the high-voltage cable (not shown) by a die-like mechanism, and the bushing coupling part 120 is connected to the bushing B. Connecting rod 140 is connected to the terminal (B-1) is assembled, through the tool access hole 125 formed on the rear of the bushing coupling portion 120 in the through hole 131 of the cable connector 130 It is fitted, this plug hole was configured by assembling the insulating cap 150 for finishing and securing insulation.
이러한 종래 기술은 상기 접속봉(140)이 상기 케이블 연결구(130)의 관통공(131)에 끼움된 상태에서 부싱결합부(120)에 끼움되는 부싱(B)의 단자(B-1)(암나사)에 배면으로 연통된 상기 공구출입공(125)을 통하여 렌찌와 같은 나사조임공구로서 나사 회전시켜 결합하도록 되어 있다.This conventional technology is a terminal (B-1) (female thread) of the bushing (B) that is fitted to the bushing coupling portion 120 in the state in which the connecting rod 140 is fitted into the through hole 131 of the cable connector 130 Through the tool access hole 125 communicated with the back surface), and is screwed into a screw tightening tool such as a wrench.
이후, 엘보접속재 자체의 손상 위험성을 최소화하고 절연 안정성을 증대시키기 위해 상기 공구출입공(125)에는 절연캡(150)을 조립하여 마감시킴으로써 상기 개통된 공구출입공(125)의 밀폐로서 절연을 제공하고 있다.Thereafter, in order to minimize the risk of damage to the elbow connecting material itself and increase the insulation stability, the tool access hole 125 is provided with insulation as a seal of the opened tool access hole 125 by assembling and closing the insulating cap 150. Doing.
그러나 이러한 종래의 엘보접속재는 상기 접속봉(140)은 숫나사부(141)가 상기 부싱(B)의 접속단자(B-1)의 암나사에 별도의 나사조임공구를 통하여 나사조임이 이루어져야만 상기 케이블연결구(130)와의 접속이 진행됨으로서 조립작업이 번거롭고, 나사조임이 확실하지 않을 경우에는 접속 불량이 발생되는 단점이 있었다.However, in the conventional elbow connecting material, the connecting rod 140 has a male screw 141 is screwed through a separate screw tightening tool to the female screw of the connection terminal (B-1) of the bushing (B) the cable As the connection to the connector 130 is in progress, the assembly work is cumbersome, and if the screw is not sure, there is a disadvantage in that a poor connection occurs.

더욱이 상기 공구출입공(125)과 절연캡(150)은 분리성을 갖는 관계로 이들의 틈새를 통한 빗물이나 습기, 이물질 침투를 차단하기 위한 절연거리의 확보가 필요하여 외부로 일정거리를 돌출시킴으로 그 절연거리의 확보를 취할 수밖에 없었다.Furthermore, since the tool access hole 125 and the insulating cap 150 have a separability, the tool entrance hole 125 and the insulating cap 150 need to secure an insulating distance to prevent rainwater, moisture, and foreign matter from penetrating through the gap, and protrude a predetermined distance to the outside. The insulation distance was bound to be secured.
이렇게 몸통부의 일부분이 심하게 돌출됨으로서 외관미가 떨어지는 단점과 공구출입공의 형성에 따른 성형 작업이 어려운 단점, 공구출입공을 마감하기 위한 절연캡의 별도 성형에 따른 불필요한 금형비의 소요되는 문제점이 있었다.As a part of the body portion protrudes badly, there is a disadvantage in that the appearance is poor and the molding operation is difficult due to the formation of the tool access hole, unnecessary mold cost due to the separate molding of the insulation cap for closing the tool access hole.
그리하여 절연의 신뢰성을 손상시키지 않고 외형치수의 증대도 없이 접속이 용이하고 제조원가가 절감되는 개선된 개폐기용 엘보접속재가 요구되고 있는 실정이었다.Therefore, there has been a demand for an improved elbow connection member for switchgear that can be easily connected and reduces manufacturing cost without impairing the reliability of insulation and without increasing the external dimensions.
