고압 차단기의 작동로드 회전 방지장치{Rotation preventing device of operating rod}Rotation preventing device of operating rod

본 발명은 고압 차단기의 작동로드 회전 방지장치에 관한 것으로서, 더욱 상세하게는 차단기의 작동 절연로드와 구동부 연결부위에 안내봉을 설치하여 고정부 접점과의 접촉을 일정하게 유지하여 고장전류 차단 및 정상전류 통전 동작이 원활히 이루어지고, 안내봉에 의해 작동 절연로드의 회전을 방지함에 따라 차단기의 개폐(open/close) 동작이 안정적으로 구현되도록 하면서 제품의 내구성을 향상시킬 수 있도록 한 고압차단기의 작동로드 회전 방지장치에 관한 것이다.The present invention relates to a device for preventing the rotation of the operating rod of the high-voltage circuit breaker, and more particularly, by installing a guide rod on the operating insulating rod and the connection of the driving part of the circuit breaker to maintain a constant contact with the contact of the fixed part breakdown current and normal The operating rod of the high-voltage circuit breaker is designed to improve the durability of the product while smoothly carrying out the current-carrying operation and preventing the rotation of the operating insulating rod by the guide rod. It relates to a rotation preventing device.

일반적으로 차단기의 경우 고정부(Fixed part)와 가동부가 접촉되어 있는 상태에서 정상전류 및 고정전류를 흘려야 하고, 전력계통에 이상이 발생하여 고장전류가 흐르게 되면 회로를 차단하여 부하 및 기타 전력기기를 보호해야 한다.In general, in case of a breaker, a steady current and a fixed current must flow while the fixed part and the moving part are in contact with each other, and when a fault occurs in the power system, a circuit breaks the circuit to disconnect the load and other power equipment. Protect

차단기의 가동부는 접점, 노즐, 파퍼실 등으로 구성되어 있으며, 구동부와 연결되어 차단을 위해 가스를 압축하고 뿜어 주는 역할을 하는 부분이다.The movable part of the breaker is composed of a contact point, a nozzle, a papersil, etc., and is connected to the driving part to compress and blow out gas for blocking.

이러한 가동부는 작동로드를 통하여 구동부의 운동을 전달받아 직선운동을 해야하며, 그 특성의 변화가 없어야 고장전류를 차단할 수 있다.Such a moving part must receive a linear motion by receiving the motion of the driving part through the operating rod, and the fault current can be interrupted only when there is no change in its characteristics.

그러나, 종래의 차단기는 작동 절연로드가 파퍼실의 실린더로드와 커플링에 의해 연결된 상태로 구동하기 때문에 전,후진 작동하면서 회전할 수 있게되고, 이러한 회전현상에 의해 고정부 접점과의 접촉이 일정하게 유지되지 못하게되어 고장전류 차단 및 정상전류 통전동작이 원활히 이루어지지 않게되는 문제점이 빈번히 발생하였다.However, the conventional circuit breaker can be rotated while moving forward and backward because the driving insulation rod is driven by coupling with the cylinder rod of the paper seal, and the contact with the fixed part contact is constant due to the rotation phenomenon. As a result of this problem, the fault current blocking and normal current conduction operations are not smoothly performed.

또한, 작동 절연로드의 회전현상에 의해 차단기의 open/close 동작이 안정적으로 이루어지지 않게되는 문제점이 발생하고 있었다.In addition, there is a problem that the open / close operation of the breaker is not made stable by the rotation phenomenon of the operating insulating rod.

따라서, 상기 문제점을 해결하기 위한 본 발명은 차단기의 작동 절연로드와 구동부를 연결하는 커플링의 양측단에 안내봉을 수직방향으로 설치하여 작동 절연로드의 직진성을 확보토록하여 고정부 접점과의 접촉이 일정하게 유지됨에 따라 고장전류 차단 및 정상전류 통전 동작이 원활히 이루어지고, 안내봉에 의해 작동 절연로드의 회전을 방지함에 따라 차단기의 open/close 동작이 안정적으로 구현되도록 하면서 제품의 내구성을 향상시킬 수 있도록 한 고압차단기의 작동로드 회전 방지장치를 제공함을 목적으로 한다.Therefore, the present invention for solving the above problems by installing the guide rods in the vertical direction at both ends of the coupling connecting the operating insulating rod and the driving unit of the circuit breaker to ensure the straightness of the operating insulating rod to contact with the fixed part contact As this constant is maintained, fault current blocking and normal current energizing operation are performed smoothly, and the open / close operation of the breaker can be stably implemented to improve the durability of the product by preventing the rotation of the operating insulation rod by the guide rod. It is an object of the present invention to provide an anti-rotation device for operation of a high pressure circuit breaker.

상기 목적달성을 위한 본 발명은, 작동절연로드와 파퍼실의 실린더로드가 커플링에 의해 연결되는 것을 포함하는 고압차단기의 작동로드 회전방지장치에 있어서, 상기 작동절연로드 및 실린더로드의 상하 직선운동을 안내하기 위한 가이드수단을 실린더로드가 축설되어 있는 플랜지의 상부면에 실린더로드와 나란하게 설치한 것을 특징으로 한다.The present invention for achieving the above object, in the operating rod anti-rotation device of the high-pressure circuit breaker comprising the coupling of the cylinder rod of the operating insulating rod and the sealer, coupling, the vertical movement of the operating rod and the cylinder rod The guide means for guiding the cylinder rod is characterized in that installed in parallel with the cylinder rod on the upper surface of the flange is installed.

본 발명에 의하면, 작동 절연로드의 회전을 방지하면서 직진성을 보장하고, 이를통해 고정부 접점과의 접촉을 일정하게 유지하여 고장전류 차단 및 정상전류 통전 동작이 원활히 이루어지고, 안내봉에 의해 작동 절연로드의 회전을 방지함에 따라 차단기의 open/close 동작이 안정적으로 구현되도록 하면서 제품의 내구성을 향상시킬 수 있도록 한 고압차단기의 작동로드 회전 방지장치를 제공하는 효과를 기대할 수 있다.According to the present invention, while preventing the rotation of the operating insulating rod to ensure the straightness, through this to maintain a constant contact with the contact of the fixed portion through the fault current blocking and normal current energizing operation is made smoothly, the operation of the insulation by the guide rod By preventing the rotation of the rod can be expected to provide the effect of providing an anti-rotation device for the operation of the high-voltage circuit breaker to improve the durability of the product while ensuring the open / close operation of the circuit breaker stably.
