도 1 은 본 발명의 진공차단기 단전위치 표시부를 보인 사시도이고, 도 2 는 본 발명의 진공차단기 운전표시부를 보인 사시도이며, 도 3 은 본 발명의 도어 인터록을 보인 측면도로서,1 is a perspective view showing a vacuum circuit breaker disconnection position display of the present invention, Figure 2 is a perspective view showing a vacuum circuit breaker operation display of the present invention, Figure 3 is a side view showing a door interlock of the present invention,

크레이들(31) 내부의 인입출입 장치(1)에 취부되어 있는 이동부(2)가 단전위치표시부에 있고, 리턴스프링으로 결합되어 있는 핸들커버(10)는 크레이들(31)에 부착되어 핸들 삽입구를 막고 있으며 우측으로 회전하도록 구성된다.The moving part 2 attached to the draw-in / out device 1 inside the cradle 31 has a disconnection position display part, and the handle cover 10 coupled to the return spring is attached to the cradle 31 to handle it. It blocks the insertion opening and is configured to rotate to the right.

그리고, 인입출입장치(1)의 중간부를 가로지르도록 형성되어 있는 이동축(6)에는 이동판(8)과 막음판(9)이 연결되어 있고, 진공차단기(38)가 개극작동할때 상기 막음판(9)과 핸들커버(10)는 떨어져있게 된다. In addition, a moving plate 8 and a blocking plate 9 are connected to the moving shaft 6 formed to cross the middle of the draw-in / out device 1, and the vacuum circuit breaker 38 is operated when the vacuum circuit breaker 38 is operated. The blocking plate 9 and the handle cover 10 are separated.                     

상기 이동부(2)의 중앙 하단부에 리턴스프링(4)에 의해 취부되어있는 누름판(3)은 리턴스프링(4)의 탄성에 의해 위로 상승된 상태로 존재하며, 지지대(5)에 의해 지지되어 뒤로 더 밀리지 않게되고, 상기 누름판(3)의 상측으로 개폐연결부(37)가 올려져있다.The pressing plate 3, which is mounted by the return spring 4 at the center lower end of the moving part 2, is present in an elevated state by the elasticity of the return spring 4, and is supported by the support 5. It is further pushed back, and the opening / closing connection portion 37 is raised to the upper side of the pressing plate 3.

이러한 상태에서 진공차단기(38)가 도 3 과같이 투입되면 개폐연결부(37)는 아래로 내려오며, 이 사이에 롤러핀(35)으로 연결되어 있는 롤러(34)가 누름판(3)을 아래로 눌러주게되고, 상기 누름판(3)은 아래방향으로 회전하면서 이동축(6)에 형성되어 있는 사각홀 사이로 들어가 이 사각홀 앞부분을 앞으로 밀어준다. 상기 이동축(6)이 앞으로 전진하면서 이동축(6)에 취부되어 있는 이동판(8)과 막음판(9)도 같이 움직이도록 구성된다.In this state, when the vacuum circuit breaker 38 is inserted as shown in FIG. 3, the opening / closing connection portion 37 descends to the bottom, and the roller 34 connected to the roller pin 35 therebetween pushes the pressing plate 3 downward. When the pressing plate 3 rotates downward, the pressing plate 3 enters between the square holes formed in the moving shaft 6 and pushes the front of the square holes forward. As the moving shaft 6 moves forward, the moving plate 8 and the blocking plate 9 mounted on the moving shaft 6 move together.

이러한 구성에 의하여 핸들커버(10)는 우측으로 회전하지 못하며 인입출입 핸들은 핸들 삽입구에 삽입될 수 없게 되고, 또한 앞으로 이동한 이동판(8)의 앞단 사각 홀에 스크류(36)에 취부 된 스프링 핀(7)이 들어오며 스크류(36)는 회전할때 스프링 핀(7)이 이동판(8)의 앞단 사각 홀에 부딪혀 스크류(36)와 결합되어 있는 이동부(2)에 연결된 진공차단기(38)를 인입출입 작동하지 못하게 하는 것이다.Due to this configuration, the handle cover 10 cannot be rotated to the right side, and the entry / exit handle cannot be inserted into the handle insertion hole, and the spring is attached to the screw 36 in the front square hole of the moving plate 8 moved forward. When the pin (7) enters and the screw (36) rotates, the spring pin (7) hits the front square hole of the moving plate (8) and is connected to the moving part (2) coupled with the screw (36). 38) to prevent the entry and exit operation.

상기 진공차단기(38)가 다시 개극되면 개폐 연결부(37)가 상승하면서 누름판(3)이 리턴스프링(4)의 탄성에 의해 상승한 후 지지대(5)에 지지되게 되고, 상기 누름판(3)이 상승함에 따라 앞으로 밀려나있던 이동축(6) 및 이 이동축(6)에 취부되어있는 이동판(8)과 막음판(9)이 뒤로밀리면서 원위치로 복귀하게된다. 그리고 사각 홀에 스프링 핀(7)이 들어가 있던 이동판(8)이 뒤로 후퇴하면서 스크류(36)의 회전이 가능하게 되고, 핸들커버(10)를 막고 있는 막음판(9)이 후퇴하면서 핸들커버(10)가 오른쪽으로 회전할 수 있게 되어 핸들커버 삽입구가 개방될 수 있게되는 것이다.When the vacuum circuit breaker 38 is opened again, the opening / closing connection portion 37 is raised while the pressing plate 3 is raised by the elasticity of the return spring 4 and then is supported by the support 5, and the pressing plate 3 is raised. As a result, the moving shaft 6 pushed forward and the moving plate 8 and the blocking plate 9 mounted on the moving shaft 6 are pushed back to return to their original positions. Then, the moving plate 8, which has the spring pin 7 in the square hole, retracts back, and the rotation of the screw 36 becomes possible, and the blocking plate 9 blocking the handle cover 10 retracts, causing the handle cover to retreat. The 10 can rotate to the right so that the handle cover insertion opening can be opened.

한편, 도 2 는 상기 이동부(2)가 운전표시부에 위치한 상태를 나타내며, 이러한 상태에서 진공차단기(38)가 투입되거나 개극될때 상기 설명과 동일한 작동을 하게된다.On the other hand, Figure 2 shows a state in which the moving unit 2 is located in the operation display unit, when the vacuum circuit breaker 38 is introduced or opened in this state to operate the same as described above.

한편, 도 4 는 본 발명의 도어 인터록을 보인 부분 측면도이고, 도 5 는 본 발명의 도어 인터록을 보인 부분 윗면도를 도시한 것으로서,On the other hand, Figure 4 is a partial side view showing a door interlock of the present invention, Figure 5 is a partial top view showing a door interlock of the present invention,
