detailed description

The specific embodiment of the utility model is described below with reference to accompanying drawing.

Refer to Figures 1, 2, 3, 4 and 5. An interlock control device for an outdoor circuit breaker on a pole, comprising a circuit breaker main box 1, a remote controller 2 and a monitoring center, the remote controller 2 is installed on the circuit breaker main box 1, the monitoring center and the remote controller 2 wireless connections. There is a manual opening and closing handle 3 on the outside of the main box 1 of the circuit breaker; the main box 1 of the circuit breaker is equipped with a rotating mechanism 4, an elastic limit device 5 on the opening side, a detection controller 6 and a switch for disconnection. Travel switch 7 for the closing coil of the circuit breaker. The rotating mechanism 4 includes a star-shaped rotating block 41 with a plurality of ends. The middle part of the star-shaped rotating block 41 is connected with the manual opening and closing handle 3. The first end of the elastic limit device 5 is rotatably installed on the main box of the circuit breaker 1. On the inner side wall, the tail end is transmission connected with the star-shaped rotating block 41, and the head end level is lower than the tail end. The travel switch 7 is located below the tail end of the elastic limit device 5, and its horizontal position is lower than the head end. At the end, the closing coil controls the remote controller 2 in chain through the detection controller 6 . By setting the rotating mechanism 4 and the elastic limiting device 5, when the manual opening and closing handle 3 is turned to the opening side, the star-shaped rotating block 41 can drive the tail end of the elastic limiting device 5 to descend, and control the action of the travel switch 7, In this way, the closing coil is disconnected, and the remote controller sends the signal of disconnecting the closing coil to the monitoring center, which effectively prevents remote false closing and greatly improves safety.

Refer to Figures 1, 2, 3, 4 and 5. The elastic limiting device 5 includes a rotating part 51 , a sliding part 52 and a compression spring 53 connecting the rotating part 51 and the sliding part 52 . The rotating part 51 is the head end of the above-mentioned elastic limiting device 5, and the sliding part 52 is the tail end of the above-mentioned elastic limiting device 5. The rotating part 51 is rotatably connected with the inner wall of the circuit breaker main box 1, and rotates in a star shape. The block 41 has a transmission end 411 which is slidably mounted on the slider 52 . A sliding channel 521 is defined on the sliding part 52 , and the transmission end 411 is slidably embedded in the sliding channel. When the manual opening and closing handle 3 is in the horizontal position, the transmission end 411 is located at one end of the sliding passage 521 close to the compression spring 53, and when the manual opening and closing handle 3 is turned to the closing state, the transmission end 411 moves to the other end of the sliding passage 521 , when the manual opening and closing handle 3 turns to the opening state, the transmission end 411 compresses the compression spring 53 and descends to touch the travel switch 7 . By setting the compression spring, when the manual opening and closing handle is turned to the opening side, the horizontal position of the rotating part 51 is higher than the horizontal position of the sliding part 52. Due to the action of the compression spring, the manual opening and closing handle 3 will not reset automatically, thus When the staff is in the opening operation, other personnel can clearly know the position of the manual opening and closing handle, effectively preventing false closing operation; The action will not be interfered by the elastic limit device 5.

Refer to Figures 1, 2, 3, 4 and 5. The rotating mechanism 4 also includes a torsion spring that controls the manual opening and closing handle 3 to return to the horizontal position. By setting the torsion spring, when the manual opening and closing handle 3 is turned to the closing side, the rotating mechanism is not subjected to the active force of the compression spring 53, but only the active force of the torsion spring, so the manual opening and closing handle can be automatically reset. When the closing handle is turned to the opening side, since the force of the torsion spring is much smaller than that of the compression spring, the manual opening and closing handle will not reset automatically.

Refer to Figures 1, 2, 3, 4 and 5. The stroke switch 7 is equipped with a stroke guide plate 71 that controls the action of the stroke switch. The stroke guide plate 71 can conflict with the transmission end 411 of the star-shaped rotating block 41. When the transmission end 411 descends, it directly acts on the stroke guide plate. 71, one end of the travel guide plate 71 is lowered, and when it is lowered to the preset position, the travel switch 7 is touched to disconnect the closing coil of the circuit breaker. By arranging the stroke guide plate 71, the star-shaped rotating block 41 does not need to directly act on the travel switch 7, but also can touch the travel switch 7 to act, so as to prevent the travel switch 7 from being damaged due to the excessive force of the star-shaped rotating block 41.

Refer to Figures 1, 2, 3, 4 and 5. The star-shaped rotating block 41 also has an opening limit end 412 and a closing limit end 413 , and a limit block 8 for limiting the rotation range of the star-shaped rotating block 41 is installed on the inner wall of the circuit breaker main box 1 . When the opening side ring 31 of the manual opening and closing handle 3 is pulled down to the 7 o'clock position of the travel switch, the opening limit end 412 is in conflict with the limit block 8, thereby limiting the continuous rotation of the manual opening and closing handle 3; When the closing side ring 32 of the closing handle 3 touches the start switch of the circuit breaker, the opening and closing limit end 413 is in conflict with the limit block 8, thereby restricting the manual opening and closing handle 3 from continuing to rotate. By setting the opening limit end 412 and the closing limit end 413, the rotation of the manual opening and closing handle 3 is kept within a certain range, preventing the equipment from being damaged due to excessive rotation.

Refer to Figures 1, 2, 3, 4 and 5. The outside of the circuit breaker main box 1 is also equipped with an on-off pointer 11 capable of displaying the on-off operation, an energy storage handle 12 and an energy storage pointer 13 displaying the energy storage state.

Refer to Figures 1, 2, 3, 4 and 5. Using the utility model includes the following steps: S1, judging that the circuit breaker is in a remote working state, and observing whether the manual opening and closing handle 3 is in a horizontal position; S2, if it is necessary to perform on-site maintenance tasks, pull down the opening side of the manual opening and closing handle 3 Ring 31, the circuit breaker is opened, the manual opening and closing handle is kept at the opening position, and at the same time disconnect the closing coil of the vacuum circuit breaker and the remote controller 2, and stop the remote control of the monitoring center; S3, pull down the manual opening and closing handle 3 The closing side ring 32 of the vacuum circuit breaker and the remote controller 2 are automatically connected to the closing coil of the vacuum circuit breaker and the remote control function of the monitoring center is restored. S4. After the manual opening and closing handle returns to the horizontal position, pull down the manual opening and closing handle on the closing side to manually close the circuit breaker. After the circuit breaker is closed, the manual opening and closing handle 3 automatically resets to the remote working state.

The above is only a specific embodiment of the utility model, but the design concept of the utility model is not limited thereto, and any non-substantial modification of the utility model by using this concept should be an act of violating the protection scope of the utility model.
