Description

진공 접촉기 인출입 안전장치{Plug interlock and earthing switch interlock of drowout mechanism in the vacuum contactor}Plug interlock and earthing switch interlock of drowout mechanism in the vacuum contactor}

본 발명은 진공 접촉기의 인출입장치에 관한 것으로, 더욱 상세하게는 기어를 사용한 인출입 장치의 동작에 제어소켓이 연동하도록 하고, 접지 스위치를 일체형으로 구성하여 연동이나 방지 동작의 신뢰성을 높이는 제어소켓 및 접지 스위치 구속장치 즉, 진공 접촉기 인출입 안전장치에 관한 것이다.The present invention relates to a drawer of the vacuum contactor, and more particularly, to the control socket is interlocked with the operation of the drawer device using the gear, the control socket to increase the reliability of the interlocking or preventing operation by integrally configuring the ground switch. And a ground switch restraint device, ie a vacuum contactor draw-out safety device.

진공 접촉기는 1000V 이상의 전력 계통에서 선로에 결합되어 개폐동작을 함에 따라 부하의 동작을 제어하는 장치로서, 개폐시 발생하는 아크를 진공 밸브내에서 소호시킨다.The vacuum contactor is a device for controlling the operation of the load as it is coupled to the line in the power system of 1000V or more to open and close, and arcs generated during the opening and closing in the vacuum valve.

이러한 진공 접촉기는 도 1에서와 같이 트럭(1), 크레들(2), 인출입장치(3)로 구성되는데, 인출입장치(3)는 이동이 가능하여 진공밸브를 내장하고 있는 트럭(1)을 크레들(2)과 접속시키거나 절연 거리만큼 크레들(2)로부터 이격시키는데 사용된다. 이때 트럭(1)과 크레들(2)이 접속되어 있는 위치를 접속위치라하고 트럭(1)부와 크레들(2)이 절연 거리만큼 이격되어 있는 위치를 시험위치라고 하고, 시험 위치에서 접속 위치로의 이동을 인입이라고 하며 시험위치에서 접속위치로의 이동을 인출이라한다.Such a vacuum contactor is composed of a truck 1, a cradle 2, a take-out device 3, as shown in Figure 1, the take-out device 3 is movable is a truck (1) containing a vacuum valve Is used to connect the cradle 2 or to separate it from the cradle 2 by an insulating distance. At this time, the position where the truck 1 and the cradle 2 are connected is called a connection position, and the position where the truck 1 and the cradle 2 are separated by an insulation distance is called a test position, and the test position is a connection position. The movement of is called pull-in and the movement from the test position to the connection position is called pull-out.

진공접촉기는 배전반에 설치되어 사용되는데 크레들(2)은 배전반의 주모선과 접촉된다.The vacuum contactor is installed and used in the switchboard, and the cradle 2 is in contact with the main bus of the switchboard.

진공접촉기를 개폐하려면 제어소켓(4)을 통하여 알맞는 정격전압을 인가하여야 한다. 제어소켓(4)에는 배전반의 제어플러그가 삽입된다.To open and close the vacuum contactor, a suitable rated voltage must be applied via the control socket (4). The control plug 4 is inserted into the control plug of the switchboard.

접지스위치(5)는 부하에 잔류하는 전류를 접지하여 감전사고에 대한 안정성을 높이는 역할을 하며, 시험위치에서만 동작 가능하다.Grounding switch 5 serves to increase the stability against electric shock by grounding the current remaining in the load, it can be operated only in the test position.

종래에는 진공 접촉기의 접촉위치에 있을 경우에도 제어소켓(4)에 삽입되는 제어 플러그가 이탈 가능하여 인위적으로 진공 접촉기 동작을 방해할 수 있다.Conventionally, even when in the contact position of the vacuum contactor, the control plug inserted into the control socket 4 is detachable, which may artificially hinder the operation of the vacuum contactor.

또한 진공 접촉기가 접속 위치에 있을 경우에는 접지스위치(5)가 투입되지 않도록 잠금 장치(6)만을 사용하고 기계적으로 연동되는 동작 방지 장치가 적절히 이루어지지 않아 기기의 안정성이 낮았다.In addition, when the vacuum contactor is in the connection position, only the locking device 6 is used so that the ground switch 5 is not inserted, and the mechanically interlocking operation preventing device is not properly made, so the stability of the device is low.

따라서 본 발명은 상기한 종래의 문제점을 개선하기 위해 창출된 것으로, 그 목적은 기어를 사용한 인출입 장치의 동작에 제어소켓이 연동하도록 하고 접지 스위치를 일체형으로 구성하여 연동, 방지 동작의 신뢰성을 높이는 인출입 안전장치를 제공하는데 있다.Therefore, the present invention has been made to improve the above-mentioned conventional problems, and an object thereof is to allow the control socket to interlock with the operation of the draw-out device using the gear, and to configure the ground switch as an integrated unit to increase the reliability of the interlocking and preventing operation. It is to provide a draw-out safety device.

A locking plate 12 which prevents the rotation of the lead screw 7, a guide 13 for guiding the movement of the horizontal moving plate 9, a spring 14 for applying a restoring force to the locking plate 12, and a vacuum. It consists of an upper and lower movable plate 15 to prevent the locking plate 12 from moving when the contactor is inserted.

수평이동판(9)의 상부에 고정된 크랭크(10)가 트럭부의 핀(16)을 잡고 있어 수평이동판(9)이 이동할 경우 트럭(1)이 함께 이동하게 된다.The crank 10 fixed to the upper portion of the horizontal moving plate (9) grabs the pin 16 of the truck portion, so that when the horizontal moving plate (9) moves, the truck (1) moves together.

진공접촉기가 투입된 경우에는 상,하이동판(15)이 위로 올라가지 않고 동시에 걸림판(12)이 리드스크류(7)의 회전을 막아 수평이동판(9)이 이동되지 않는다.When the vacuum contactor is inserted, the upper and lower movable plates 15 do not move up, and at the same time, the locking plate 12 prevents the rotation of the lead screw 7 so that the horizontal movable plate 9 does not move.

도 3은 진공접촉기의 제어소켓 구성장치의 구성을 나타낸다.3 shows a configuration of a control socket constituting apparatus of the vacuum contactor.

진공접촉기의 제어소켓(4)에 제어플러그(17)가 삽입되지 않으면 (가)와 같이소켓구속막대(18)가 위로 올라가지 않고 동시에 걸림판(12)이 리드스크류(7)의 회전을 막아 수평이동판(9)이 이동되지 않는다.If the control plug 17 is not inserted into the control socket 4 of the vacuum contactor, as shown in (a), the socket restraint bar 18 does not move up, and at the same time, the locking plate 12 prevents the rotation of the lead screw 7 so that it is horizontal. The moving plate 9 does not move.

진공접촉기가 인입이 시작되면 (나)와 같이 후크 지지대(19)가 플러그를 고정시키고 있는 소켓 후크(20)의 회전을 막아 플러그가 이탈되지 않도록 한다.When the vacuum contactor starts drawing, as shown in (b), the hook support 19 prevents rotation of the socket hook 20 holding the plug so that the plug is not detached.

도 4는 진공접촉기의 접지 스위치 구속장치의 구성을 나타낸다.Figure 4 shows the configuration of the ground switch restraint device of the vacuum contactor.

접지스위치가 투입되면 접지스위치용 축(21)이 회전하면서 접지스위치용 걸림막대(22)가 회전판(23)에 의하여 이동하여 걸림판(12)의 회전을 막아 결국 수평이동판이 이동되지 않게 되며, 동시에 후크지지대(24)를 회전시켜 후크(25)가 들려올려져 배전반 도어(26)가 열릴 수 있게 된다. 배전반 도어가 닫혀있으면 부쉬 멈춤판(27)이 회전하여, 접지 스위치 동작 핸들(28)을 삽입하면 부쉬(29)가 밀려들어가 접지스위치 투입이 가능하게 된다.When the ground switch is inserted, the ground switch shaft 21 rotates, and the ground switch stop bar 22 is moved by the rotating plate 23 to prevent the rotation of the stopping plate 12, so that the horizontal plate does not move. At the same time, the hook support 24 is rotated to lift the hook 25 so that the switchboard door 26 can be opened. When the switchboard door is closed, the bush stop plate 27 rotates, and when the ground switch operation handle 28 is inserted, the bush 29 is pushed in to allow the ground switch to be inserted.

본 발명은 진공 차단기 인출입장치를 종래와 달리 제어소켓 구성장치와 접지 스위치 구성 장치를 일체형으로 구성하여 연동이나 방지 동작이 별도의 조작없이 인출입 동작만으로 확실하게 동작하여 각종 안전사고를 방지하는 효과가 있다.According to the present invention, unlike the related art, the vacuum breaker draw-out device is integrated with the control socket component device and the ground switch component device, so that the interlocking or preventing operation is reliably operated only with the draw-out operation without any separate operation, thereby preventing various safety accidents. have.
