일반적으로 굵고 중량이 나가는 고전압 케이블을 개폐기에 접속하거나 탈속하는 매개수단으로 표준 T형 접속재가 사용되었다.In general, a standard T-type connecting member was used as a medium for connecting or disconnecting a thick and heavy high voltage cable to a switch.

이러한 25.8kV의 고전압 접속 및 분기에 사용되는 개폐기용 T형 접속재는 종래에도 다양한 기술도 개시되고 있다.Various technologies have also been disclosed in the T-type connection member for switchgear used for high voltage connection and branching of 25.8 kV.

도 1에 도시된 일 예의 T형 접속재를 살펴보면, 고무(Rubber)와 같은 절연물의 내부절연층과 상기 내부절연층의 내, 외부에 고무(Rubber)과 같은 탄성중합물의 반도체성 보호층으로 감싸서 상호 간 관통된 복층구조로서 수직방향의 케이블 수용부(11)와 수평방향의 부싱 결합부(12)와 전압검출부(13)가 좌우 대칭구조의 성형 된 T-형 절연하우징(10)을 포함하고 있다.Referring to the example of the T-type connecting member shown in FIG. 1, the inner insulating layer of an insulator such as rubber and the inside of the inner insulating layer are wrapped in a semiconductor protective layer of an elastic polymer such as rubber in and out of the inner insulating layer. As a multi-layered structure, the cable receiving part 11 in the vertical direction, the bushing coupling part 12 in the horizontal direction, and the voltage detection part 13 include a molded T-shaped insulating housing 10 having a symmetrical structure. .

상기 케이블 수용부(11)의 내부 공간을 통하여 고전압 케이블(C/A)의 도선을 다이스와 같은 압착기구에 의해 연결하여 상기 부싱 결합부(12)와 전압검출부(13)의 중앙 내부에 돌출된 상태로 컨덕터(20)가 조립된다.The conductive wire of the high voltage cable C / A is connected by a crimping mechanism such as a die through an inner space of the cable accommodating part 11 to protrude inside the center of the bushing coupling part 12 and the voltage detecting part 13. In the state, the conductor 20 is assembled.

이때, 상기 케이블(C/A)은 케이블 수용부(11)의 내부 공간에서 절연외피에 조립된 별도의 아답터(30)에 의해 유동이 없이 결합 된다.At this time, the cable (C / A) is coupled without flow by a separate adapter 30 assembled in the insulating jacket in the inner space of the cable receiving portion (11).

상기 컨덕터(20)에는 고전압기기인 개폐기에 조립된 부싱의 접속단자에 나사회전으로 접속되는 스터드볼트와 같은 접속봉(14)이 상기 부싱 결합부(12)의 전단을 통하여 조립된다.In the conductor 20, a connecting rod 14, such as a stud bolt, is connected to the connecting terminal of the bushing assembled in the switch, which is a high voltage device, through the front end of the bushing coupling part 12.

이러한 접속봉과 부싱의 접속단자는 상기 전압검출부(13)의 후단에서 조립되는 플러그(40)의 회전에 의한 나사조임으로 접속 고정하고 있다.The connecting terminal of the connecting rod and the bushing is connected and fixed by screwing by rotation of the plug 40 assembled at the rear end of the voltage detecting unit 13.

상기 플러그(40)는 상기 접속봉(14)의 후단을 나사결합하는 조임너트와, 전압을 감지하여 선로의 활선상태를 확인하거나, 전원측과 부하측의 검상 및 결상상태를 체킹하기 위한 테스트 포인트(41)가 절연물질의 전, 후단에 인서트 성형으로 조립되었다.The plug 40 is a fastening nut for screwing the rear end of the connecting rod 14 and the test point (41) for checking the live state of the line by sensing the voltage, or check the inspection and imaging of the power side and load side ) Is assembled by insert molding before and after the insulating material.

그리고 이러한 플러그(40)는 전압검출부(13)의 후단에 결합하여 상기 고전압 케이블(C/A)과의 직접적인 연결에 의해 발생하는 열 차단, 노출된 테스트포인트(41)의 차폐에 의한 안전성 목적으로 조작고리(51)를 돌출하여 고무(Rubber) 재질로 일체 성형 된 절연캡(50)이 사용된다.And the plug 40 is coupled to the rear end of the voltage detector 13 for the purpose of safety by heat shielding by the direct connection with the high voltage cable (C / A), shielding of the exposed test point 41 An insulating cap 50 integrally molded of rubber material is used to protrude the operation ring 51.

이러한 T형 개폐기용 접속재는 수직방향의 케이블 수용부(11)을 중심으로 수평방향으로 일체 성형 된 부싱 결합부(12)와 전압검출부(13)이 좌우 대칭구조로 제공되어 상기 부싱 결합부(12)의 전압검출부 측의 돌출길이가 커지고, 전압검출부의 보호를 위해 마감처리되는 절연캡(50)에 돌출 성형 된 조작고리(51)로 인해 돌출부분의 더욱 증가로 인한 개폐기의 외함도 대응하여 커지는 단점이 있었다.The connection member for the T-type switch has a bushing coupling portion 12 and a voltage detector 13 integrally formed in a horizontal direction around the cable receiving portion 11 in a vertical direction, and are provided in a symmetrical structure so that the bushing coupling portion 12 is provided. The protruding length on the side of the voltage detector increases, and the enclosure of the switchgear due to the further increase of the protruding portion also increases due to the operation ring 51 protrudingly formed on the insulating cap 50 which is finished for protection of the voltage detector. There was a downside.

또한, 케이블 고정을 위한 별도의 아답터와 알루미늄 재질의 컨덕터를 사용함에 따라 케이블 수용부의 직경 및 길이가 커짐에 따른 제품 단가가 상승하는 요인으로 지적되었고, 별도의 아답터 채용에 따른 계면의 증가로 결함요소의 발생에 의한 절연성능이 저하되는 단점이 있었다.In addition, as a separate adapter and an aluminum conductor are used for fixing the cable, it is pointed out that the product cost increases as the diameter and length of the cable accommodating part increases, and the increase in the interface due to the adoption of a separate adapter causes a defect. There was a disadvantage that the insulation performance is reduced by the generation of.

이에 본 발명에서는 절연하우징에 일체 성형되는 부싱결합부의 전압검출부 측을 최대한 줄여 비대칭형으로 성형하고, 이에 조립되는 플러그 또한 최대한 줄임과 동시에 상기 플러그의 테스트포인트를 차폐하는 절연캡의 조작고리를 절첩형으로 구성하여 부싱결합부의 전압검출부 측의 돌출크기를 최대한 줄임으로써 절연하우징의 부피 축소 및 제조원가를 최대한 절감하는 것을 특징적 목적으로 한다.Accordingly, in the present invention, the voltage detecting part of the bushing coupling part integrally formed in the insulating housing is minimized and molded into the asymmetrical shape, and the plugs assembled therein are also reduced as much as possible and the operation ring of the insulating cap for shielding the test point of the plug is folded.
