[0029] Please refer to the following: Figure 1 , Figure 2 and Figure 3 ,in, Figure 1A schematic diagram of the structure of a first embodiment of an integrated sealed primary and secondary fusion pole-mounted circuit breaker provided by this utility model; Figure 2 for Figure 1 The enlarged schematic diagram of part A shown below; Figure 3 for Figure 1 The enlarged schematic diagram of part B is shown.

[0030] An integrated sealed primary and secondary combined pole-mounted circuit breaker includes: an electrical box 1;

[0031] The circuit breaker handle 4 is rotatably mounted on one side of the surface of the electrical box 1. The circuit breaker handle 4 includes a movable plate 41, an adjusting block 42, and a slot 43. The middle of the movable plate 41 is rotatably mounted on one side of the surface of the electrical box 1 via a rotating shaft. The two adjusting blocks 42 are respectively fixedly mounted on both sides of the outer surface of the movable plate 41. The slot 43 is opened in the middle of one side of the adjusting block 42.

[0032] Adjustment device 5 is disposed on one side of the surface of the electrical box 1 and located in front of the opening / closing handle 4. The adjustment device 5 includes a mounting frame 51, a first motor box 52, a rotating plate 53, and traction columns 54. The mounting frame 51 is fixedly installed on one side of the surface of the electrical box 1 and located in the middle in front of the movable plate 41. The first motor box 52 is fixedly installed in the middle of one side of the mounting frame 51. The rotating plate 53 is fixedly connected to the end of the motor output shaft inside the first motor box 52. The two traction columns 54 are respectively fixedly installed on both sides of the outer surface of the rotating plate 53.

[0033] Energy storage handle 6 is rotatably mounted on the other side of the surface of the electrical box 1. An adjustment plate 7 is provided on the surface of the energy storage handle 6, and a movable groove 8 is provided in the middle of the surface of the adjustment plate 7.

[0034] A connecting rod 9 is fixedly installed on the surface of the electrical box 1. A fixing plate 10 is fixedly installed at one end of the connecting rod 9. A sliding groove 11 is opened in the middle of one side of the fixing plate 10. A second motor box 12 is fixedly installed in the middle of the top of the fixing plate 10. A reciprocating screw 13 is rotatably installed in the middle of the sliding groove 11. A push rod 14 is threadedly connected to the outer surface of the reciprocating screw 13.

[0035] The electrical box 1 is equipped with three vacuum tubes 3 on its top.

[0036] Both the first motor box 52 and the second motor box 12 are equipped with servo motors.

[0037] The surface of the push rod 14 is provided with a threaded hole 15, and the push rod 14 is threadedly connected to the outer surface of the reciprocating lead screw 13 through the threaded hole 15.

[0038] The traction column 54 extends into the interior of the slot 43, and the push rod 14 extends into the interior of the movable slot 8.

[0039] The three vacuum tubes 3 installed on the top of the electrical box 1 have built-in vacuum bulbs, which can seal the internal vacuum circuit breaker equipment and improve the safety and reliability of the equipment.

[0040] One side of vacuum tube 3 is connected to an independent zero-sequence current transformer and other equipment, all of which are existing devices.

[0041] The first motor box 52 waterproof seals the internal servo motor. The output shaft of the servo motor rotates alternately in both directions, driving the rotating plate 53 to rotate alternately in both directions. The traction columns 54 on both sides of the rotating plate 53 rotate alternately, thereby controlling the opening and closing handle 4 to perform opening and closing operations.

[0042] The push rod 14 passes through the movable groove 8. When the push rod 14 moves up and down inside the movable groove 8, it pushes the adjustment plate 7 to rotate around the energy storage handle 6 as the axis.

[0043] The working principle of the integrated sealed primary and secondary fusion pole-mounted circuit breaker provided by this utility model is as follows:

[0044] During operation, the servo motor in the first motor box 52 is started first, which drives the rotating plate 53 to rotate. The rotating plate 53 drives the traction column 54 to move in the slot 43. Due to the traction effect of the traction column 54, the movable plate 41 will rotate around the rotating shaft, thereby realizing the automatic opening and closing operation of the opening and closing handle 4. There is no need to manually shake the opening and closing handle 4, which reduces the labor intensity of the operator.

[0045] Simultaneously, the servo motor in the second motor box 12 is started, driving the reciprocating screw 13 to rotate in the slide groove 11. Since the push rod 14 is threaded to the outer surface of the reciprocating screw 13 through the threaded hole 15, the rotation of the reciprocating screw 13 will drive the push rod 14 to make reciprocating linear motion in the slide groove 11. The push rod 14 extends into the interior of the movable groove 8, which will drive the adjusting plate 7 to rotate around the energy storage handle 6 as the axis, thereby driving the energy storage handle 6 to rotate, realizing the automatic energy storage operation of the energy storage handle 6. Similarly, there is no need to manually shake the energy storage handle 6, and the circuit breaker can be remotely controlled to automatically store energy and automatically open and close.

[0046] Compared with related technologies, the integrated sealed primary and secondary fusion pole-mounted circuit breaker provided by this utility model has the following beneficial effects:

[0047] This utility model provides an integrated sealed primary and secondary fusion pole-mounted circuit breaker. By setting an adjustment device 5 to adjust the rotation of the opening and closing 5, the reciprocating screw 13 controls the push rod 14 to move up and down to realize the automatic rotation of the energy storage handle 6. This realizes the automatic operation of the opening and closing handle 4 and the energy storage handle 6, which solves the problem that the prior art requires manual adjustment, increases the labor intensity of operators, and has poor practicality, and reduces the labor intensity of operators.
