Description

Technical Field

[0002] As a new type of high-voltage circuit breaker, high-voltage vacuum circuit breaker is increasingly widely used because it can achieve breakdown and disconnect current in a vacuum environment. During installation, it is necessary to repeatedly pull the energy storage rod so that the energy storage spring in the high-voltage circuit breaker can store energy for the subsequent opening of the high-voltage circuit breaker, thereby ensuring that the opening and closing can be carried out effectively and quickly.

[0003] However, when installing the high-voltage circuit breaker in the existing structure, if the installation construction personnel forget to store energy in the circuit breaker body, the operator needs to climb up the electric pole again, or use a long pole to pull the handle on the ground to store energy in the energy storage spring in the circuit breaker body, which is very time-consuming. In addition, during the installation of the circuit breaker body and the bracket, the circuit breaker body is generally fixed to the bracket by multiple bolts. This fixing method will take up a lot of time for the user during installation or disassembly, resulting in the existing high-voltage circuit breaker being particularly inconvenient during installation, reducing work efficiency and being inconvenient for users.

A limiting rod 821 is arranged on the slider 82, and the limiting rod 821 passes through the side wall of the base 3. A connecting rod 83 is rotatably arranged between the sliders 81 and the sliders 82. By passing the limiting rod 821 through and embedding it in the pushing plate 232, the fixing effect of the circuit breaker body 1 and the bracket 2 is further improved. At the same time, the cooperation between the sliders 81 and the connecting rod 83 makes the overall structure more stable.

[0042] See also Fig. 9 The fixing mechanism 7 includes a plurality of sleeve rods 71, which are arranged on the base 3, and the sleeve rods 71 ​​are rotatably connected to the base 3. The sleeve rods 71 ​​are sleeved with an action gear 73, and the sleeve rods 71 ​​are provided with a screw rod 72 through a thread, and a limiting block 721 is provided at the upper end of the screw rod 72. A plurality of limiting sleeves 74 are provided on the lower surface of the circuit breaker body 1, and the limiting sleeves 74 are sleeved on the screw rod 72.

[0043] See also Figure 11-12 The bracket 2 is provided with a mounting groove 21, the base 3 can be embedded in the mounting groove 21, a plurality of nuts 22 are rotatably provided on the bracket 2, the screw rod 72 is movably connected with the nut 22, a movable seat 23 is slidably provided in the mounting groove 21, a return spring 231 is provided between the movable seat 23 and the upper surface of the mounting groove 21, a plurality of connecting plates 235 are slidably provided on the lower surface of the bracket 2, a connecting rod 234 is provided between the connecting plate 235 and the movable seat 23, a plurality of avoidance grooves 233 are provided on the bracket 2, and a push spring 231 is provided after the connecting plate 235 passes through the bracket 2 The plate 232, the push plate 232 is arranged on the four sides of the installation groove 21, and the movable seat 23 is squeezed to make the position drop, and the reset spring 231 can be reset immediately after the movable seat 23 is released from the pressure, and the relative push plate 232 can be moved a specified distance by adjusting the length of different connecting rods 234, so as to adjust the position and angle of the circuit breaker body 1, so that the nut 22 can be accurately located under the screw rod 72, and the installer does not need to repeatedly adjust the position of the circuit breaker body 1 on the bracket 2.

[0044] See also Fig.10 A through hole 31 is provided on the base 3, and the limiting rod 821 passes through the side wall of the base 3 through the through hole 31. A hole is provided on the push plate 232, and the limiting rod 821 can be embedded in the hole. A convex seat 32 is provided on the lower surface of the base 3. The convex seat 32 prevents the screw rod 72 from being squeezed when the circuit breaker body 1 is placed flat, and leaves a certain space for the screw rod 72 and the nut 22 to prevent the bottom surface of the base 3 from causing pressure on the nut 22.

[0045] Before installation, support and level the bracket 2, lift the circuit breaker body 1 by a crane, place it above the installation slot 21, and slowly lower it. When the circuit breaker body 1 enters the installation slot 21, the circuit breaker body 1 squeezes the movable seat 23 to make the movable seat 23 descend. During the descent of the movable seat 23, the movable seat 23 drives the push plate 232 to move inward by the connecting rod 1 234, so as to push the suspended circuit breaker body 1. When the circuit breaker body 1 completely falls into the installation slot 21, the circuit breaker body 1 just reaches the center position of the installation slot 21, and the nut 22 just lies below the screw rod 72. Insert the handle into the polygonal hole of the second cross bar 61, and turn the handle to make the second cross bar 61 rotate, so that the driving gear 62 and the screw rod 72 are connected. The linkage gear 51 rotates at the same time, and the driving gear 62 causes the driven gear 64 to drive the bevel gear 65 to rotate through the chain 2 63, so that the sleeve rod 71 rotates. Since the screw rod 72 is restricted by the restriction sleeve 74, it cannot rotate and can only move in the vertical direction, so that the screw rod 72 descends. When the screw rod 72 is embedded in the nut 22, as the screw rod 72 continues to descend, the nut 22 rotates on the screw rod 72, and the chain 3 75 and the chain 2 63 are used to make the multiple sleeve rods 71 ​​rotate synchronously, so as to fix the base 3 in the installation groove 21, so as to use the movable push plate 232 to make the base 3 more conveniently and accurately move to the center position of the installation groove 21, and avoid the need for multiple screws to fix the circuit breaker body 1 and the bracket 2;

[0046] When the linkage gear 51 rotates, the linkage gear 51 uses the chain 1 53 to make the toothed disc 521 rotate forward, and then drives the cross bar 1 41 to rotate through the ratchet 2 523. When the cross bar 1 41 rotates, the ratchet 1 432 idles in the installation disk 431, thereby avoiding the movement of the handle 42. In this way, as the cross bar 1 41 continues to rotate, the energy storage mechanism in the circuit breaker body 1 stores energy for subsequent opening and closing. In this way, during the process of installing the bracket 2 and the circuit breaker body 1, the circuit breaker body 1 starts to store energy, thereby avoiding the installation personnel from causing the circuit breaker body 1 to be damaged after the installation is completed. Under the premise of forgetting the energy storage operation due to negligence, it is necessary to store energy again, and pull the handle 42 back and forth in the later stage to make the installation disk 431 rotate forward, and use the ratchet 1 432 to rotate the cross bar 1 41, and when storing energy again, the rotation of the cross bar 1 41 uses the idle rotation of the ratchet 2 522, which will not affect the toothed disk 521, so that the energy storage operation can be completed during the installation of the circuit breaker body 1 and the bracket 2, avoiding the situation that the installer forgets to store energy, and when it is necessary to store energy again in the later stage, the movement of the handle 42 will not affect the cross bar 2 61;

[0047] While the cross bar 61 is rotating, the cross bar 61 causes the slider 81 thereon to move inward, thereby pushing the slider 82 to both sides until the limiting rod 821 is embedded in the hole of the push plate 232 through the through hole 31, thereby further improving the fixing effect of the circuit breaker body 1 and the bracket 2. In this way, after the circuit breaker body 1 and the bracket 2 are fixed and the energy storage is completed, the circuit breaker body 1 is continued to be lifted together with the bracket 2 by the crane, and the circuit breaker body 1 is fixed to the electric pole by the bracket 2, and then the wiring operation is performed to complete the overall installation of the circuit breaker body 1.
