이하, 첨부된 도면 도 1 과 도 2 를 참조하여 본 발명의 바람직한 실시예를 설명하면 다음과 같다.Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings, FIGS. 1 and 2.

도 1 에 도시된 바와같이 가스절연 차단기의 내부에는 가스의 투입 및 차단을 위한 진공차단기(9)가 설치되어 있으며, 진공차단기(9)는 가스차단기 내부에 구비된 차단기구동부의 기계적인 동작에 의해 차단 및 트립 동작하게되며, 차단기구동부의 기계적인 동작에 의해 전달된 동력을 진공차단기로 전달 및 유지시키는 것이 도 2 에 도시된 바와같은 진공차단기 구동장치이다.As shown in FIG. 1, a vacuum circuit breaker 9 is installed in the gas insulated circuit breaker for inputting and blocking a gas, and the vacuum circuit breaker 9 is operated by a mechanical operation of the circuit breaker provided inside the gas circuit breaker. The breaker and trip operation are performed, and the vacuum breaker driving device as shown in FIG. 2 transmits and maintains the power transmitted by the mechanical operation of the shutoff mechanism drive unit to the vacuum breaker.

도면부호 1 은 진공차단기 구동장치의 주된 동작원으로 작동하는 주회전축을 나타낸다.Reference numeral 1 denotes a main axis of rotation that operates as a main operating source of the vacuum circuit breaker drive device.

상기 주회전축(1)의 외주면 상에 핀으로 링크(2)를 연결하여 주회전축(1)의 회전력이 링크(2)로 전달되도록 하고, 상기 링크(2)에 핀으로 스프링 압축링크(3)을 연결하는데, 이 스프링 압축링크(3)는 주작동로드(4)에 힘을 전달함과 동시에 작동로드(4)의 이동이 완성되는 시점에 압축 스프링(5)에 압축을 가하는 기능을 갖는다.The link 2 is connected to the link 2 on the outer circumferential surface of the main rotation shaft 1 so that the rotational force of the main rotation shaft 1 is transmitted to the link 2, and the spring compression link 3 is connected to the link 2 by a pin. The spring compression link 3 has a function of transmitting a force to the main operating rod 4 and compressing the compression spring 5 at the time when the movement of the operating rod 4 is completed.

상기 주작동로드(4)는 진공밸브의 주축과 직접 연결된 것으로서, 이 주작동로드(4)의 끝단부를 상기 스프링 압축링크(3)의 중간부에 핀으로 연결하여 스프링 압축링크(3)가 상향 회전할때 그 회전력을 전달받아 진공밸브를 폐로시킨다.The main operation rod 4 is directly connected to the main shaft of the vacuum valve, and the end of the main operation rod 4 is connected to the middle portion of the spring compression link 3 with a pin so that the spring compression link 3 is upward. When it rotates, it receives the torque and closes the vacuum valve.

그리고, 도면부호 5 는 압축스프링을 나타내는 것으로서, 차단기 폐로시 충격흡수 및 주전원 연결유지기능을 갖는다.In addition, reference numeral 5 denotes a compression spring, and has a function of absorbing shock and maintaining the main power connection when the breaker is closed.

한편, 상기 압축스프링(5)을 지지하는 고정조절자(6)를 압축조정샤프트(8) 상에 형성하고, 상기 압축조정샤프트(8)에는 고정조절자(6)의 위치를 가변 및 고정시키기 위한 압축조정볼트(7)를 결합하는데, 상기 압축조정볼트(7)를 조정하여 고정조절자(6)의 위치를 가변시킴에 따라 압축스프링(5)의 초기 압축력을 조정할 수 있음은 물론 진공차단기 내부적 마모에 대응하여 압축스프링(5)의 압축력을 보상할 수 있게되어 진공차단기의 차단 및 트립 동작이 신속하게 이루어질 수 있도록 한다.On the other hand, a fixed adjuster 6 for supporting the compression spring (5) is formed on the compression adjusting shaft (8), and the position of the fixed adjuster (6) is variable and fixed to the compression adjusting shaft (8) Combining the compression adjustment bolt (7) for adjusting the position of the fixed adjuster (6) by adjusting the compression adjustment bolt (7) can adjust the initial compression force of the compression spring (5) as well as the vacuum circuit breaker It is possible to compensate for the compressive force of the compression spring 5 in response to internal wear so that the blocking and tripping operation of the vacuum circuit breaker can be made quickly.

이와같이 구성된 본 발명의 작용 및 효과를 설명하면 다음과 같다.Referring to the operation and effects of the present invention configured as described above are as follows.

도 2 는 본 발명의 진공차단기 구동장치가 개로된 상태를 도시한 것으로서, 차단기의 투입이 이루어질때 주회전축(1)이 시계방향으로 회전하면서 링크(2)를 상단으로 들어올리게된다.FIG. 2 shows a state in which the vacuum circuit breaker driving device of the present invention is opened, and when the input of the circuit breaker is made, the main shaft 1 rotates clockwise to lift the link 2 upward.

이때, 스프링 압축링크(3)는 링크(2)의 상승에 힘입어 상단 베어링부를 기준으로 반시계방향으로 이동하게되고, 이때 스프링 압축링크 (3)의 중앙에 연결되어 있는 주작동로드(4)가 도면상의 좌측방향으로 이동하면서 최초 진공밸브의 폐로를 구성한다.At this time, the spring compression link (3) is moved counterclockwise with respect to the upper bearing portion by the rise of the link (2), at this time the main operating rod (4) connected to the center of the spring compression link (3) Moves to the left in the drawing to constitute the closing of the first vacuum valve.

이러한 상태로 주회전축(1)이 지속적으로 시계방향으로 회전하게되면 주작동로드(4)는 진공밸브의 폐로로 인하여 더이상 움직이지 못하게되고 이때부터 스프링 압축링크(3)가 압축스프링(3)을 압축하게된다.When the main shaft 1 rotates clockwise continuously in this state, the main operation rod 4 can no longer move due to the closing of the vacuum valve, and from this time, the spring compression link 3 opens the compression spring 3. Will be compressed.

상기 압축스프링(3)이 압축됨에 따라 차단기 폐로 작동시 충격을 흡수함은 물론 주전원이 연결상태를 유지하게된다.As the compression spring 3 is compressed, the main power is kept connected as well as absorbs shock when the breaker is closed.

한편, 상기 설명과 같은 차단기의 개로 및 폐로 작동이 지속적으로 반복되면 진공밸브의 작동단이 마모되어 압축스프링(5)의 압축력 저하를 가져올 수 있는데, 이때 작업자가 압축조정볼트(7)를 조여주어 고정조절자(6)가 압축스프링(5) 측으로 이동되도록 함에 따라 압축스프링(5)의 압축력을 보상해줄 수 있게되는 것이다.On the other hand, if the opening and closing operation of the circuit breaker as described above is continuously repeated, the operating end of the vacuum valve may be worn, leading to a decrease in the compression force of the compression spring (5), in which the operator tightens the compression adjustment bolt (7) As the fixed adjuster 6 is moved to the compression spring 5 side, it is possible to compensate for the compression force of the compression spring 5.

즉, 진공차단기 내부적으로 마모가 발생되었을때 전체 차단기를 분해 조립하지 않고서도 압축조정볼트(7)의 조정으로 간편하게 압축스프링(5)의 압축력을 보상해줄 수 있게되는 것이다.That is, when wear occurs inside the vacuum circuit breaker, the compression force of the compression spring 5 can be easily compensated by adjusting the compression adjustment bolt 7 without disassembling and assembling the entire circuit breaker.

이상에서 설명한 바와같이 본 발명은 주회전축의 외주면상에 핀으로 링크를 연결하고, 주작동로드에 힘을 전달함과 동시에 작동로드의 이동이 완성되는 시점에 압축 스프링에 압축을 가하는 스프링압축링크를 상기 링크에 핀으로 연결하며, 진공밸브의 주축과 직접 연결된 작동로드의 끝단부를 상기 스프링 압축링크의 중간부에 핀으로 연결하고, 차단기 폐로시 충격흡수 및 주전원 연결유지기능을 하는 압축스프링을 상기 스프링 압축링크의 끝단에 접속시키되, 상기 압축스프링을 지지하는 고정조절자를 압축조정샤프트 상에 형성하고, 상기 압축조정샤프트에는 고정조절자의 위치를 가변 및 고정시키기 위한 압축조정볼트를 결합한 것으로, 이를 통해 상부에 폐로가 완성된 진공밸브의 압축 조정을 신속히 구현함은 물론 마모에도 간단한 압축조정볼트 조절을 통해 일정하게 원래의 압축력을 유지할 수 있으며, 차단 및 트립동작이 신속하게 이루어질 수 있도록 한 가스절연 차단기의 진공차단기 구동장치를 제공하는 효과를 기대할 수 있다.As described above, the present invention provides a spring compression link that connects the link with a pin on the outer circumferential surface of the main rotating shaft, transmits a force to the main working rod, and simultaneously compresses the compression spring when the movement of the working rod is completed. The spring is connected to the link with a pin, and the end of the operating rod directly connected to the main shaft of the vacuum valve is connected to the middle part of the spring compression link by a pin, and the spring has a compression spring that functions to absorb shock and maintain the main power connection when the breaker is closed.
