이와 같이 다양한 절연개폐장치가 개발되어 있고, 이들은 절연수단으로 SF6 가스를 사용하고 있으나, 이 SF6 가스는 6개 감축 대상 온실가스 중 온난화지수가 23,900 (CO2 : 1기준)으로 지구온난화에 가장 큰 영향을 미치는 가스로 판명되었다. 이에 세계 각 나라에서는 온실가스 감축 목표를 설정하여 온실가스의 감축을 위해 노력하고 있으며, 철도차량의 경우에도 2023부터 29kV 친환경 절연개폐장치를 철도에도 적용하기로 했으며, 전압레벨에 따라 72.5kV, 170kV 2 종류의 설비는 2025년부터 전면 적용할 계획이다.As such, various insulated switchgears have been developed, and they use SF 6 gas as an insulation means, but this SF 6 gas has a warming potential of 23,900 (based on CO 2 : 1) among the 6 greenhouse gases to be reduced, contributing to global warming. It was found to be the most influential gas. Accordingly, countries around the world are making efforts to reduce greenhouse gases by setting greenhouse gas reduction targets, and in the case of railway vehicles, it is decided to apply 29kV eco-friendly insulation switchgear to railways from 2023, and depending on the voltage level, 72.5kV and 170kV The two types of facilities are planned to be fully applied from 2025.

또한 종래의 절연개폐장치는 도 1에 도시한 바와 같이 단로기(100)와 차단기(200)들이 각각 분리 구성됨에 따라 이들이 많은 공간을 차지함에 따라 전기실의 공간 확보가 어렵고, 이들과 조작기(300) 사이의 거리가 멀어 작동시 오동작의 위험이 있으며, 비효율적으로 배열(전후 배열)됨에 따라 이들을 작동시키는 작업자가 불필요한 구성요소를 오작동시키는 문제가 있다.In addition, as shown in FIG. 1, in the conventional insulated switchgear, as the disconnector 100 and the circuit breaker 200 are separately configured, it takes up a lot of space, making it difficult to secure space in the electrical room, and between them and the manipulator 300 There is a risk of malfunction during operation due to the large distance between them, and as they are inefficiently arranged (arranged in front and back), there is a problem that a worker operating them malfunctions unnecessary components.

상기 단로기, 차단기, 모선, 및 제어부는 통상의 절연개폐장치를 구성하는 구성요소와 동일하게 작동하는 것으로 이에 대한 상세한 설명은 생략한다.The disconnector, circuit breaker, bus bar, and control unit operate in the same way as the components constituting a conventional insulation switchgear, and detailed description thereof will be omitted.

도 1에 도시한 종래의 절연개폐장치가 단로부, 차단부, 모선부가 일체로 결합되어 구성됨에 따라 어느 하나에 고장이 발생하면 장치 전체를 분해하여 수리하여야 하는 데 반하여, 상기와 같이 구성된 본 발명의 친환경 모듈형 절연개폐장치는 도 8에 도시한 바와 같이, 단로부, 차단부, 모선부가 각각 축소 모듈화되어 서로 분해 조립될 수 있게 구성됨에 따라 어느 하나의 구성요소에 고장이 발생하면 해당 구성요소만을 분해하여 수리할 수 있음에 따라 유지보수를 용이하게 할 수 있다.As the conventional insulation switchgear shown in FIG. 1 is configured by integrally combining the disconnecting unit, the blocking unit, and the busbar unit, when a failure occurs in any one, the entire unit must be disassembled and repaired, whereas the present invention configured as described above As shown in FIG. 8, the eco-friendly modular insulation switchgear of the disconnection unit, the blocking unit, and the busbar unit are respectively reduced and modularized so that they can be disassembled and assembled together, so that when a failure occurs in any one component, the corresponding component Maintenance can be facilitated by disassembling and repairing the bay.

또한 본 발명의 친환경 모듈형 절연개폐장치는 도 3 내지 도 7에 도시한 바와 같이, 제어부(조작부)를 기준으로 단로부, 차단부, 모선부가 좌우 배치됨에 따라 장치가 차지하는 공간을 줄일 수 있다.In addition, as shown in FIGS. 3 to 7, the eco-friendly modular insulation switchgear of the present invention can reduce the space occupied by the device as the disconnecting part, the blocking part, and the bus part are arranged on the left and right with respect to the control unit (manipulation unit).

또한 본 발명의 전기철도용 친환경 모듈형 절연개폐장치는 도 3, 도 9 및 도 11에 도시한 바와 같이 제어부(30)를 단로부와 차단부에 적접 설치하여 제어부와 각각의 단로부 및 차단부 사이의 거리를 줄임에 따라 제어부의 제어에 따른 단로부와 차단부의 스위치 장치를 작동시키는 작동수단의 길이가 줄어 제어부에 의한 제어동작이 단로부, 차단부에 전달되는 과정에서 아류를 일으키는 것을 방지할 수 있다. In addition, the eco-friendly modular insulation switchgear for electric railways of the present invention, as shown in FIGS. 3, 9 and 11, directly installs the control unit 30 on the disconnecting unit and the blocking unit, and between the control unit and each disconnecting unit and blocking unit. As the distance of is reduced, the length of the operating means for operating the switch device of the disconnecting unit and the blocking unit according to the control of the control unit is reduced, preventing a subclass from occurring in the process of transmitting the control operation by the control unit to the disconnecting unit and the blocking unit. there is.

즉, 통상적으로 제어부(조작부)의 제어에 의해 단로부, 차단부의 위치를 작동시키는 작동수단은 긴 로드 형태로 이루어지고, 이러한 작동로드의 길이가 길어지면 작동 중 휘거나 뒤틀림이 발생하여 원하는 정도로 단로부와 차단부를 작동시킬 수 없으나, 본 발명은 제어부와 단로부 및 차단부 사이의 거리가 줄어 작동수단의 길이가 줄고, 이에 따라 작동과정에서 작동수단의 변형이 덜 발생함에 따라 정밀한 제어가 이루어질 수 있는 것이다.That is, in general, the operating means for operating the position of the disconnecting unit and the blocking unit under the control of the control unit (manipulation unit) is made in the form of a long rod. It is impossible to operate the unit and the blocking unit, but in the present invention, the distance between the control unit, the disconnecting unit and the blocking unit is reduced, so the length of the operating means is reduced, and thus, as the deformation of the operating means is less generated during the operation process, precise control can be achieved. There is.

특히, 상기 단로부(10)의 접속단자(10t)는 제어부의 구동수단에 의해 구동하는 스크류축(40s)에 의해 이동하게 하였다.(도 9 및 10 참조)In particular, the connection terminal 10t of the disconnecting unit 10 is moved by the screw shaft 40s driven by the driving means of the control unit (see FIGS. 9 and 10).

즉, 제어부(30)를 구성하는 구동모터(미도시)의 구동에 의해 상기 스크류축(40S)이 회전함에 따라 접속단자가 이동하여 도 10에 도시한 바와 같이 접지에 접속, 단선 또는 접속 위치로 이동할 수 있게 하였다.That is, as the screw shaft 40S rotates by driving a driving motor (not shown) constituting the controller 30, the connection terminal moves to a ground connection, disconnection, or connection position as shown in FIG. 10. made it possible to move.

또한 본 발명의 전기철도용 친환경 모듈형 절연개폐장치는 상기 단로부, 차단부 및 모선부들 사이에는 절연SPACER(CS)가 더 설치되어 구성요소들 사이의 분해 결합을 용이하게 함과 동시에 이들 사이의 접속부로 누수가 발생하거나 공기가 통과하여 절연이 파괴되는 것을 방지하였다.In addition, in the eco-friendly modular insulation switchgear for electric railways of the present invention, an insulation spacer (CS) is further installed between the disconnection unit, the blocking unit, and the busbar to facilitate disassembly and coupling between the components, and at the same time, the connection between them This prevents leaks or air from passing through and destroying the insulation.

상기 절연SPACER(CS)은 절연 소재로 만들어지고, 도시한 바와 같이 두 구성요소들의 단부에 밀착되는 플랜지부(CS-1)를 포함하고, 이 플랜지부를 중심으로 양측에 각 구성요소들의 내부로 끼워져 내벽에 밀착되는 통형 날개(CS-2)를 구비하고 있다.The insulating spacer (CS) is made of an insulating material, and as shown, includes a flange portion (CS-1) in close contact with the ends of the two components, and the flange portion is centered on both sides to the inside of each component. Equipped with a tubular wing CS-2 that is fitted and closely adhered to the inner wall.
