An operating end is equipped with an earthing contact, a service contact, and a disconnecting contact in a single insulator mold, and a multi-bend protrudes on both ends of the inner end of the terminal.

일반적으로 통전하고 있는 도체는 그 자계와 전류와의 계수에 의하여 동일 방향의 전류일 경우는 인력이, 반대 방향의 전류일 경우는 반발력이 발생한다.In general, a conductor that is energized generates a attraction force when the current is in the same direction and a repulsive force when the current is in the opposite direction, based on the coefficient between the magnetic field and the current.

이때 통전시 예기치 못한 단락사고가 발생했을 경우 비대칭 전류가 흐르며 시간의 경과에 따라 대칭값에 근접한다.If an unexpected short circuit occurs during energization, an asymmetrical current flows and approaches the symmetry value over time.

단락사고가 발생하면 전자력이 단락전류의 제곱승에 비례하여 커지며 시간의 크기에 따라 도체에 발생되는 열도 커지므로 도체를 지지하고 있는 단(Contact)의 중요성을 인식하여 단락사고를 대비한 충분한 기계적강도와 발생열에 견딜 수 있는 절연재질을 선택하여 사용되어져야 한다.When a short circuit occurs, the electromagnetic force increases in proportion to the square of the short-circuit current, and the heat generated in the conductor increases according to the size of the time, so that the mechanical strength is sufficient to prepare for the short circuit by recognizing the importance of the contact supporting the conductor. Insulation materials that can withstand the generated heat must be used.

종래의 가스 절연 배전반에 설치되는 개폐장치는 수직형 단로기,수직형 3단 개폐기 등이 있으며 그 구조는 다수의 구성부품을 결합시켜 다단의 링크로 구성되어 기계적으로 접지 및 폐로 작동시켜 사용하였다.The switchgear installed in the conventional gas insulated switchgear includes a vertical disconnector, a vertical three-stage switch, and the structure is composed of a plurality of links by combining a plurality of components and mechanically grounded and closed.

상기와 같은 종래의 개폐장치는 구성부품의 부피가 커서 넓은 공간을 차지하므로 가스 절연 배전반의 전체크기가 커지는 문제가 있으며 또한 다단의 링크구조로 형성되어 그 구조가 복잡하고 접지 및 폐로 작동시 오작동이 발생하는 문제점이 있었다. The conventional switchgear as described above has a problem that the overall size of the gas insulated switchgear is large because the volume of the component is large and occupies a large space. In addition, the structure is complicated by a multi-stage link structure. There was a problem that occurred.

따라서 본 발명은 상기한 종래의 문제점을 해결하기 위한 목적으로 창출된 것으로 3단 개폐장치의 동작 접점을 수동 또는 전동식으로 폐로-개로-접지 및 폐로-개로로 작동하는 슬라이딩 방식을 채택하여 단락시 발생하는 전자력,중력 및 진동에 의한 우발적인 개폐동작을 하지 않도록 하여 안전사고를 미연에 방지하고 보조 접점을 통하여 각 정해진 위치에서 정확한 출력신호를 나타낼 수 있게하여 모선을 연결시키거나 패쇄시키고 잔류전압을 대지로 방전시킬 수 있게한 3단 개폐장치를 제공하기 위한 것이다.
Therefore, the present invention has been created for the purpose of solving the above-mentioned conventional problems, the operation contact of the three-stage switchgear occurs by a sliding method of operating the closed-opening-ground and the closed-opening by manual or electric operation. It prevents accidental opening and closing by electromagnetic force, gravity and vibration, which prevents accidents and shows the correct output signal at each fixed position through auxiliary contact to connect or close the bus and ground the residual voltage. It is to provide a three-stage switchgear that can be discharged.

상기한 3단 개폐장치를 제공하기 위하여 접지단,폐로단 및 개로단을 단일 절연물 몰드에 장착시키고 상기 각단의 내측으로 양측 선단에 멀티 밴드가 돌출 설치된 작동단을 절연 스핀들의 스크류에 결합시키고 모터를 구동시켜 작동단을 슬라이딩시켜 가스 구획 내에 설치된 모선에 연결시켜 기기 내부의 점검 및 수리시 주회 로를 접지시키거나 전원을 공급 및 차단시킬 수 있게 하였으며 또한 비상시에는 수동핸들을 회전 샤프트에 결합시켜 스크류를 회전시켜 각 단을 연결 및 단락시킬 수 있게 하였다.In order to provide the three-stage switchgear, the ground end, the closing end, and the open end are mounted on a single insulator mold, and the operating end having multi-band protruding on both ends inside the ends is coupled to the screw of the insulating spindle and the motor is connected. By driving the sliding stage, it is connected to the bus bar installed in the gas compartment so that the main circuit can be grounded or powered on and off during inspection and repair of the equipment. Rotation allowed each stage to be connected and shorted.

상기의 폐로단과 개로단은 개로 상태에서 충전부와의 절연을 확보한 구조이고 단락시 발생하는 전자력,중력 및 진동에 의해 오작동에 의한 개폐동작을 못하게 스크류 회전에 의한 슬라이딩 방식의 작동을 수행하게 하여 주회로를 접지,전원공급 및 차단하는 3단 개폐장치를 제공할 수 있게한 것이다.
The closed end and the open end have a structure that ensures the insulation from the live part in the open state, and performs the sliding type operation by screw rotation to prevent the opening and closing operation by malfunction due to the electromagnetic force, gravity and vibration generated during short circuit. It is possible to provide a three-stage switchgear for grounding, powering and disconnecting circuits.
