Description

가스절연 개폐장치용 모선 접지개폐기 유니트와 포텐셜 트랜스퍼(PT)의 접속구조Connection structure of busbar grounding switch unit for gas insulated switchgear and potential transfer

본 고안은 가스절연 개폐장치에 관한 것으로서, 더욱 상세하게는 모선 접지개폐기 유니트와 포텐셜 트랜스퍼를 수평접속에서 수직접속으로 구조 변경하여 레이아웃(Lay out) 구성시 원가절감은 물론 가스절연 개폐장치의 공간점유율을 줄일 수 있도록 한 가스절연 개폐기장치용 모선 접지개폐기와 유니트 포텐셜 트랜스퍼의 접속구조에 관한 것이다.The present invention relates to a gas insulated switchgear, and more particularly, the structure of the bus ground switch unit and the potential transfer is changed from a horizontal connection to a vertical connection so as to reduce the cost when constructing a layout, and to occupy space in the gas insulated switchgear. The present invention relates to a connection structure of a bus earth ground switch and a unit potential transfer device for a gas insulated switchgear device which can reduce the voltage.

일반적으로 가스절연 개폐장치(GIS)는 금속제 밀폐용기에 절연성능과 소호기능(아아크 발생을 억제하는 기능)이 우수한 SF6 가스를 절연매체로 사용하여 도체와 각종보호기기들을 수납시켜 신뢰성을 향상시킨 수변전 설비로서 각종기기 및 접속관들을 유니트화시켜 조합함으로써 전체 시스템을 구성하게 된다.In general, a gas insulated switchgear (GIS) uses SF6 gas, which has excellent insulation performance and arc extinguishing function (to suppress arcing), in a metal sealed container as an insulating medium to accommodate conductors and various protective devices to improve reliability. As a substation facility, various systems and connecting pipes are unitized and combined to form an entire system.

종래 가스절연 개폐장치는 도 1에서와 같이 크게 모선 접지개폐기 유니트(1)와 포텐셜 트랜스퍼(Potential Transfer)(2)로 구성되어 있으며, 상기 두 유니트는 직선 접속관(3)에 의해 수평으로 연결(또는 접속)되어 있다.Conventional gas insulated switchgear is composed of a busbar grounding switch unit 1 and a potential transfer (2) as shown in Figure 1, the two units are connected horizontally by a straight connection pipe (3) Or connected).

상기 모선 접지개폐기 유니트(1)는 외형을 구성하고 있는 탱크(4)와, 상기 탱크에 내장된 상,하부 유니트(5)(6)와, 상기 상,하부 유니트를 연결하는 연결도체(7)등으로 구성되어 있다.The busbar grounding switch unit 1 includes a tank 4 constituting an outer appearance, upper and lower units 5 and 6 embedded in the tank, and a connecting conductor 7 connecting the upper and lower units. And the like.

상기 상부 유니트(5)는 탱크(4)의 일측 상부에 결합되어 있는 스페이서(8)에 연결된 상부도체(9)를 일컬으며, 하부 유니트(6)는 지지애자(10)와 이에 조립되어 있는 하부도체(11)를 일컫는다.The upper unit 5 refers to an upper conductor 9 connected to a spacer 8 coupled to an upper portion of one side of the tank 4, and the lower unit 6 includes a support insulator 10 and a lower portion assembled thereto. The conductor 11 is called.

또한, 상기 상부 유니트(5)의 일측에는 메가링 단자(12)와 샤프트(13)로 구성된 조작기(14)가 설치되어 있는데, 이 조작기는 탱크(4)에 조립되어 있다.In addition, a manipulator 14 composed of a mega ring terminal 12 and a shaft 13 is provided on one side of the upper unit 5, which is assembled to the tank 4.

따라서, 평상시 개방되어 있던 접지 개폐기는 샤프트(13)에 결합된 조작기(14)를 동작시키면 샤프트(13)가 수평으로 동작함에 따라 샤프트(13)의 선단에 설치된 가동접촉자(15)도 수평으로 동작하여 고정접촉자(16)에 투입된다.Therefore, when the ground switch is normally open, when the manipulator 14 coupled to the shaft 13 is operated, the movable contact 15 provided at the tip of the shaft 13 also operates horizontally as the shaft 13 operates horizontally. Is inserted into the fixed contact 16.

이에 따라 도체에 잔류되어 있던 전류를 제거하게 된다.This removes the current remaining in the conductor.

그러나 상기와 같은 종래의 가스절연 개폐장치는 모선 접지개폐기 유니트(1)와 포텐셜 트랜스퍼(2)연결시 직선 접속관(3)으로 접속해야 하는 구조이므로 설치공간상에 제약을 받게 되는 문제점이 있었다.However, the conventional gas insulated switchgear as described above has a problem in that it is restricted in the installation space because it is a structure to be connected by a straight connection pipe 3 when the bus ground switch unit 1 and the potential transfer 2 are connected.

이에 따라 가스절연 개폐기의 큰 장점인 용지 및 용적축소에 위배되어 레이 아웃 구성에 따른 원가상승의 주 요인이 되어 왔다.Accordingly, it has violated the paper and volume reduction, which is a major advantage of the gas insulated switchgear, and has been a major factor in the cost increase due to the layout configuration.

본 고안은 상기와 같은 종래의 문제점을 해결하기 위해 안출한 것으로서, 그 목적은 접지개폐기의 상부에 포텐셜 트랜스퍼(PT)를 직접 접속함으로써 가스절연 개폐기의 전체 용적을 축소시킬 뿐만아니라 레이 아웃구성을 용이하게 할 수 있도록 하기 위한 것이다.The present invention has been made to solve the conventional problems as described above, the purpose is to directly connect the potential transfer (PT) to the upper portion of the grounding switch to reduce the overall volume of the gas insulated switchgear as well as facilitate the layout of the layout. It is to make it possible.

상기와 같은 목적을 달성하기 위한 본 고안은 모선 접지개폐기 유니트의 상부에 포텐셜 트랜스퍼(PT)가 접속된 것을 특징으로 하는 가스절연 개폐장치용 모선 접지개폐기 유니트와 포텐셜 트랜스퍼(PT)의 접속구조를 제공함에 있다.The present invention for achieving the above object provides a connection structure of the main earth ground switchgear unit and the potential transfer (PT) for gas insulated switchgear, characterized in that the potential transfer (PT) is connected to the upper portion of the bus bar ground switch unit. Is in.

도면의 주요부분에 대한 부호의 설명Explanation of symbols for main parts of the drawings

1 : 모선 접지개폐기 유니트 2 : 포텐셜 트랜스퍼(PT)1: Bus ground switch unit 2: Potential transfer (PT)

7 : 연결도체7: connecting conductor

이하, 첨부된 도 2를 참조하여 가스절연 개폐장치의 구성을 상세히 설명하면 다음과 같다.Hereinafter, with reference to the accompanying Figure 2 will be described in detail the configuration of the gas insulated switchgear.

가스절연 개폐장치는 모선 접지개폐기 유니트(1)와, 포텐셜 트랜스퍼(PT)(2)로 구성되어 있다.The gas insulated switchgear is composed of a bus bar ground switch unit 1 and a potential transfer (PT) 2.

상기에서 포텐셜 트랜스퍼(2)는 모선 접지개폐기 유니트(1)의 상부에 직접 연결되어 있다.In the above, the potential transfer 2 is directly connected to the upper portion of the bus ground switch unit 1.

그 구성은 종래와 대동소이 하지만 직선 접속관(3)과 스페이서(8)를 제거함에 따라 점유공간의 축소 및 부품수를 줄일 수 있게 된다.Although the configuration is almost the same as in the prior art, by eliminating the straight connection pipe 3 and the spacer 8, it is possible to reduce the occupied space and reduce the number of parts.

즉, 종래에 상부도체(9)와 하부도체(11)를 연결하였던 연결도체(7)를 연장하여 하부도체(11)와 포텐셜 트랜스퍼(2)를 연결하고 있다.That is, the lower conductor 11 and the potential transfer 2 are connected by extending the connecting conductor 7 which has conventionally connected the upper conductor 9 and the lower conductor 11.

따라서, 평상시에는 가동접촉자(15)가 개방된 상태에서 모선 접지개폐기 유니트(1)의 일측에 설치된 조작기(14)를 수동 또는 자동으로 조작하면 조작기(14)에 연결된 샤프트(13)가 좌,우로 이동되면서 이 샤프트에 연결된 가동접촉자(15)를 좌우로 이동시킴에 따라 가동접촉자(15)가 고정접촉자(16)에 투입 및 트립된다.Therefore, normally, when the movable contactor 15 is opened, the manipulator 14 installed on one side of the bus-bar grounding switch unit 1 is operated manually or automatically, and the shaft 13 connected to the manipulator 14 moves left and right. As the movable contactor 15 connected to the shaft is moved left and right while being moved, the movable contactor 15 is input and tripped to the fixed contactor 16.

이에 따라 도체에 잔류된 전류가 제거된다.This removes the current remaining in the conductor.

이상과 같이 모선 접지개폐기 유니트에 포텐셜 트랜스퍼를 수직으로 연결하여 직선 접속관 및 스페이서 등의 부품을 줄일 수 있음은 물론, 기기의 점유공간을 축소할 수 있으므로 레이 아웃이 용이한 효과가 있다.As described above, by connecting the potential transfer vertically to the bus ground switch unit, components such as linear connectors and spacers can be reduced, as well as the space occupied by the device can be reduced, so that the layout can be easily effected.
