본 고안은 배선용 차단기의 투입방지 장치에 관한 것으로, 특히 차단기의 일측에 투입방지장치를 설치하여 이를 동작시켜 놓았을때는 어떠한 경우라도 투입불가능록 하므로서, 부하설비 보수시 개방된 전도에 오투입에 의한 사고를 방지토록 하는 장치를 제공함에 주안점을 둔 것이다.The present invention relates to an input preventing device for a circuit breaker, and in particular, when an input preventing device is installed on one side of the circuit breaker and operated, the input can not be inserted in any case, and thus, due to incorrect input to open conduction during repair of the load facility. The main focus is on providing a device to prevent accidents.
일반적으로 배선용 차단기는 케이스내에 개폐작동기구(1)와, 상기 개폐작동기구측의 홀더와 결합된 가동접촉자(4) 및 고정접촉자(5), 소호장치(6) 그리고 드립장치(7)를 결합설치하여 구성되며, 정규상태의 전도에서 수동으로 핸들(8)을 조작하여 개방과 투입 조작할 수 있으며, 과부하 및 단락전류가 흐르는 경우는 드립장치가 이를 감지하여 전로를 자동차단하는 작용을 행한다.In general, the circuit breaker couples the opening / closing operation mechanism 1 and the movable contactor 4 and the fixed contactor 5, the extinguishing device 6, and the drip device 7 coupled to the holder on the side of the opening and closing mechanism. It is installed and configured, and can be opened and closed by manually operating the handle 8 in the conduction of the normal state, and when the overload and short-circuit current flow, the drip device detects this and cuts off the converter.
즉, 정규상태의 전로에서 핸들(8)을 투입방향으로 동작시키면 개폐작동기구(1)에 의해 홀더(17)가 선회 동작하여 가동접촉자(4)를 고정접촉자(5)에 접촉시켜 전로가 시켜 전로가 폐로로 형성되고, 과전류 단락전류가 발생되면 바이메탈(9)과 히터(10) 또는 고정마그네트(11)에서 과전류 및 단락전류를 검출하여 가동철편이 트립기구부에 연결되어 있는 드립크로스바(12)를 쳐주게 되며, 이에 의해 트립레버(13)와, 래치홀더(14)의 결합이 해제되어 전로가 자동적으로 차단된다.That is, when the handle 8 is operated in the input direction in the converter in the normal state, the holder 17 is pivoted by the opening and closing operation mechanism 1 so that the movable contactor 4 is brought into contact with the fixed contactor 5 to be transferred. When the converter is formed into a closed circuit and an overcurrent short circuit current is generated, the drip cross bar 12 in which the bimetal 9 and the heater 10 or the fixed magnet 11 detects the over current and the short circuit current and the movable iron piece is connected to the trip mechanism part. In this case, the coupling of the trip lever 13 and the latch holder 14 is released, and the converter is automatically cut off.
그런데, 상기와 같은 종래의 배선용 차단기는 핸들을 내려서 전로를 개방시킨 상태를 계속유지시키기 위한 어떠한 차단유지 수단도 구비되어 있지 않는 관계로, 차단기를 오프시켜 전로를 개방시킨상태에서 부하설비보수 작업시 제3자등에 의한 오조작으로 핸들을 투입 시켰을 경우 감전 및 주변기기의 파손사고가 발생하는 문제가 있었다.However, since the conventional circuit breaker as described above does not have any interruption holding means for keeping the converter open by lowering the handle, when the load facility maintenance work is performed with the circuit breaker open. When the handle was put in by a wrong operation by a third party, there was a problem of electric shock and damage of peripheral equipment.
따라서, 본 고안의 목적은 상기와 같은 종래의 문제점을 해결함과 동시, 배선용 차단기의 일측에 개방 상태를 계속적으로 유지시킬 수 있는 투입방지장치를 제공함에 있다.Accordingly, it is an object of the present invention to solve the conventional problems as described above, and at the same time, to provide an input preventing device that can continuously maintain the open state on one side of the circuit breaker.
상기와 같은 목적을 달성하기 위하여, 핸들의 온/오프 동작에 따라 선회동작하는 홀더의 일측에 정지레버를 설치하고, 케이스 상측커버의 일측에는 키에 의해 정역회전 동작하는 실린더를 구비한 사건장치를 설치하면서 실린더의 하단에는 선회위치에 따라 함께 선회하여 상기 홀더의 정지레버와 접촉내지 분리동작토록 하는 선회동작봉을 설치하므로서, 핸들을 오프상태로 내려놓고 키로서 실린더를 돌려 선회동작봉이 홀더의 정지레버 전방측에 위치토록 하면, 홀더가 이에 걸려 회존하지 못하므로 핸들을 이용한 투입이 행해지지 않도록 한 것으로, 이를 첨부된 도면에 의거 상세히 설명하면 다음과 같다.In order to achieve the above object, a stop lever is provided on one side of the holder that rotates according to the on / off operation of the handle, and on one side of the upper cover of the case there is a case apparatus having a cylinder for forward and reverse operation by a key. While installing, the lower end of the cylinder is pivoted together according to the turning position so that the turning bar can be contacted or separated from the stop lever of the holder so that the handle is turned off and the cylinder is turned with a key to stop the turning bar. When the lever is located on the front side, the holder is caught so that it does not rotate so that the input is not performed using the handle, which will be described in detail with reference to the accompanying drawings.
제2,3도에서와 같이 핸들(8)과 연동으로 시소 운동하는홀더(17)의 상부일측에는 정지레버(17a)를 고정설치하였고, 설치된 키(18)에 의해서 만이 록크해제되어 정 또는 역방향으로 회전 하는 실린더(20)를 하우징(21)내에 설치하여서된 사건장치(19)가 케이스의 상측커버(3)일측에 고정결합 설치되면서, 상기 실린더(20)의 하단에는 상기 홀더(17)의 정지레버(17a)와 접촉될 절곡부(22a)를 구비한 선회동작봉(22)을 동시선회토록 고정결합 시켜서된 것이다.As shown in Figs. 2 and 3, a stop lever 17a is fixedly installed on the upper side of the holder 17 moving in conjunction with the handle 8 in a seesaw manner, and the lock is released only by the installed key 18. The case device 19 installed by installing the cylinder 20 rotating in the housing 21 is fixedly installed on one side of the upper cover 3 of the case, and the lower end of the cylinder 20 of the holder 17 The pivoting rod 22 having the bent portion 22a to be in contact with the stop lever 17a is fixedly coupled to rotate simultaneously.
이와같이 구성됨에 따라, 키(18)를 이용하여 실린더(20)를 잠금위치 90°회전시키면, 그 하단에 고정 결합시킨 선회동작봉(22)이 함께 선회하여 말단이 절곡부(22a)가 홀더(17)상의 정지레버(17a)전방에 위치하게 되므로 홀더의 회전 즉 핸들의 온 위치 이동이(투입작용)행해지지 않게 된다.(제3b도 참조) 실리더(20)를 해제위치로90°역회전시키면 선회동작봉의 절곡부(22a)가 홀더의 정지레버측에서 멀리 이격되므로 홀더에 대한 제어가 해제되면서 핸들의 투입 위치전환 동가이 가능케 된다(제3a도 참조)As such, when the cylinder 20 is rotated by 90 ° by using the key 18, the pivoting rod 22 fixedly coupled to the lower end pivots together so that the end portion of the bent portion 22a is supported by the holder ( Since it is located in front of the stop lever 17a on 17), the holder's rotation, i.e., the on position movement of the handle, is not carried out (see also 3b). When rotated, the bent portion 22a of the swinging rod is spaced far away from the stop lever side of the holder, and thus the control of the holder is released, thereby allowing the movement of the handle into the feeding position (see FIG. 3a).
이상과 같이 케이스의 상측 커버일측에 설치되는 시건장치(19)와, 그에 따라 선회동작하는 선회동작봉(22) 및, 선회동작봉 말단의 절곡부(22a)에 의해 제어되는 홀더상의 정지레버(17a)로 구성된 투입방지 장치를 이용하여, 전로 개방위치로 이동시킨 핸들에 대한 록크 작용으로 인위적인 록크해제전에는 투입이 전혀 행해지지 않도록 하므로서, 핸들을 제쳐서 전로를 개방시켜 놓고 부하설비 보수등을 행할때 핸들 오조작에 의한 안전사고를 완벽하게 방지할 수 있으며, 배선용 차단기의 안전도를 향상시켜서 제품의 품질과 신뢰도를 향상 시킬 수 있는 특출한 효과가 있다.As described above, the stop device on the holder controlled by the locking device 19 provided on one side of the upper cover of the case, the swinging operation rod 22 that rotates accordingly, and the bent portion 22a of the end of the swinging operation rod ( By using the closing prevention device composed of 17a), the locking action on the handle moved to the converter opening position prevents any closing before artificial lock release. The safety accidents caused by mishandling of the handle can be completely prevented, and the safety and safety of the circuit breaker can be improved, which has the special effect of improving the quality and reliability of the product.
