Description

Technical Field

[0001] The invention relates to the technical field of high-voltage switches, in particular to a high-voltage motor integrated starter. Background Art

[0002] There are two general methods for direct starting of existing high-voltage motors: one is to use a combination of a vacuum contactor and a fuse, with the contactor acting as a switching switch and the fuse acting as a backup fault protection; the other is to use a vacuum circuit breaker and a vacuum contactor, with the contactor acting as a switching switch and the vacuum circuit breaker acting as a fault protection switch.

[0041] Specifically, in this embodiment, three circuit breaker channels 22 are provided, and the circuit breaker structure 2 and the contactor structure 3 are arranged horizontally as a whole and aligned with each other vertically;

[0043] The interlocking mechanism 5 slides between the spring operating mechanism 21 and the electromagnetic operating mechanism 31, and its input end is arranged on the spring operating mechanism 21, and the output end is movably connected to the electromagnetic operating mechanism 31. Specifically, in this embodiment, the interlocking mechanism 5 includes an interlocking push rod 51 and an indicator plate 52 for pushing the interlocking push rod 51 to move toward the electromagnetic operating mechanism 31. The interlocking push rod 51 slides in the through hole of the electromagnetic operating mechanism 31 and is provided with a step portion. A tightening spring 53 is provided between the step portion and the electromagnetic operating mechanism 31.

Specifically, One end of the ground indicator plate 52 in the length direction is hinged to a swing arm, and the other end of the swing arm away from the indicator plate 52 is fixed to the swing shaft, and the swing shaft is rotatably connected to the frame 211. The other end of the indicator plate 52 in the length direction is hinged with a rotating arm, and the rotating arm is transmission-connected to the spring operating mechanism 21. The indicator plate 52 has a bending portion that abuts against the input end of the interlocking push rod 51, and the bending portion is located near the rotating arm. The end away from the swing shaft is the lower end and faces the electromagnetic operating mechanism 31; the chassis 6 is covered on the chassis vehicle 1 and insulates and separates the circuit breaker channel 22, the contact channel 32 and the insulating phase column 4.

[0044] like Figure 9-11 As shown, the spring operating mechanism 21 includes a frame 211, in which a first driving device 212, a closing energy storage device 213, an opening energy storage device 214, a transmission device 215 and an output device 216 fixedly connected to the first insulating rod 23 are arranged. The closing energy storage device 213 is used to store energy under the action of the first driving device 212 and release energy so that the transmission device 215 drives the output device 216 to drive the first insulating rod 23 to close. The opening energy storage device 214 is used to store energy and release energy when closing so that the transmission device 215 drives the output device 216 to drive the first insulating rod 23 to open.

[0045] The first driving device 212 includes an energy storage motor 2121, a driving shaft 2122 pivoted on the frame 211, a cam 2123 fixedly connected to the driving shaft 2122, and a rotating disk 2124 connected to the energy storage motor 2121, wherein the rotating disk 2124 is provided with an eccentric shaft 2125, and the transmission device 215 includes an intermediate shaft 2151 framed in the frame 211, a connecting plate 2152 with one end fixedly connected to the intermediate shaft 2151 and matched with the cam 2123, and a connecting rod 2153 pivotally connected to the connecting plate 2152 away from the intermediate shaft 2151, wherein the intermediate shaft 2151 is matched with the rotating arm through a master-slave gear structure, and the output device 216 includes a plurality of output shafts 2161 pivotally connected to the frame 211 and corresponding to the circuit breaker channel 22, a middle An output crank arm 2162 is rotatably connected to the output shaft 2161, one end of the output crank arm 2162 is pivotally connected to the connecting rod 2153, and the other end is fixedly connected to the first insulating pull rod 23. The closing energy storage device 213 includes a closing spring 2131 and a closing holding device 2132. One end of the closing spring 2131 is connected to the frame 211, and the other end is connected to the eccentric shaft 2125. The closing holding device 2132 cooperates with the cam 2123 to realize energy storage of the closing spring 2131. The opening energy storage device 214 includes a first opening spring 2141 and an opening holding device 2142. One end of the first opening spring 2141 is connected to the connecting rod 2153, and the other end is connected to the frame 211. The opening holding device 2142 cooperates with the connecting plate 2152 to realize opening energy storage.

[0046] The closing holding device 2132 includes a closing half-axis pivoted to the frame 211, an energy storage sector plate pivoted to the frame 211 and a closing holding roller arranged on the cam 2123. The roller of the cam 2123 abuts against the energy storage sector plate, and the energy storage sector plate abuts against the closing half-axis. Since the cam 2123 cannot rotate due to the restriction of the energy storage sector plate and the closing half-axis, a torsion spring is arranged between the energy storage sector plate and the frame 211. The torsion spring generates elastic force, which makes the energy storage sector plate abut against the closing half-axis.

[0047] The switch-off holding device 2142 includes a switch-off half-shaft pivoted to the frame 211, a holding member pivoted to the frame 211, and a switch-off holding roller provided on the connecting plate 2152, the roller of the connecting plate 2152 abuts against the holding member, and the holding member abuts against the switch-off half-shaft; a switch-off releaser is provided, the switch-off releaser is mounted on the frame 211 and cooperates to drive the switch-off half-shaft. A torsion spring is provided between the holding member and the frame 211, and the torsion spring generates an elastic force, which causes the holding member to abut against the switch-off half-shaft.

[0048] like Figure 12-14 As shown, the electromagnetic operating mechanism 31 has a base 311 and a second driving device 312 arranged on the base 311, a transmission main shaft 313 is passed through the base 311, an action crank arm 314, an energy storage crank arm 315, and a holding crank arm 316 are mounted on the transmission main shaft 313, a second opening spring 317 is provided between the energy storage crank arm 315 and the base 311, an electromagnetic holding device 318 is provided between the holding crank arm 316 and the base 311, and the second driving device 312 enables the action crank arm 314 to drive the transmission main shaft 313 to achieve closing.

[0049] The second driving device 312 includes an electromagnetic actuator 3121 fixed on the base 311, a working seat 3122 adapted to the electromagnetic actuator 3121, and a pivot member 3123 pivotally connecting the working seat 3122 and the action crank arm 314. The electromagnetic actuator 3121 and the working seat 3122 are adapted to each other. The holding mechanism includes an upper holding latch 3181 pivotally connected to the base 311 for holding the transmission main shaft 313 and the crank arm 316, a rotating block 3182 for holding the upper holding latch 3181, and a lower holding latch 3183 for holding the rotating block 3182.

[0050] The working principle of the starter is as follows: the closing and opening of the circuit breaker structure 2 is controlled by the spring operating mechanism 21, and the first insulating pull rod 23 drives the moving and static contacts of the corresponding circuit breaker arc extinguishing chamber 24 to close and open; the closing and opening of the contactor structure 3 is controlled by the electromagnetic operating mechanism 31, and the moving and static contacts of the corresponding contactor arc extinguishing chamber 34 are driven to close and open through the second insulating pull rod 33;

[0051] When the spring operating mechanism 21 is working to store energy, the energy storage motor 2121 drives the rotating disk 2124 to rotate, thereby driving the closing spring 2131 to stretch. When the closing spring 2131 is fully energy-stored, the power is provided by the roller on the cam 2123 to contact the energy storage sector plate and constrain the energy storage sector plate and the closing half-shaft. When the circuit breaker is to be closed, the closing button is manually pressed or the closing release is activated to push the closing half-shaft to rotate, thereby releasing the constraint between the energy storage sector plate and the roller. The energy of the closing spring 2131 is released, driving the cam 2123 to rotate. The cam 2123 hits the connecting plate 2152 to rotate, and the output crank arm 2162 is rotated through the connecting rod 2153, driving the first insulating pull rod 23 to move to achieve closing. The indicator plate 52 will move synchronously with the connecting rod 2153. The moving direction of the indicator plate 52 is the same as that of the connecting rod 2153. Since the interlocking push rod 51 has only the freedom to slide between the circuit breaker structure 2 and the contactor structure 3, during the movement of the indicator plate 52, the input end of the interlocking push rod 51 and the lower end of the bent portion of the indicator plate 52 will move away from each other, causing the output end of the interlocking push rod 51 to move in a direction away from the electromagnetic operating mechanism 31. At this time, the interlocking push rod 51 is in an unlocked state for the electromagnetic operating mechanism 31. When the switch is in place, the retaining member contacts the roller on the connecting plate and causes the retaining member to be constrained by the opening half shaft, completing the closing action.

[0052] When the contactor structure 3 is then closed: the electromagnetic actuator 3121 drives the transmission main shaft 313 to rotate forward through the base 311 and achieves closing, and the second opening spring 317 is compressed to store energy, the upper retaining latch 3181 latches the upper retaining roller on the transmission main shaft 313, the stop pin of the rotating block 3182 blocks the upper retaining latch 3181, and the lower retaining latch 3183 latches the lower retaining roller on the rotating block 3182, so that the switch remains in the closed position.

[0053] On the contrary, when the spring operating mechanism 21 performs the opening operation, the opening button or the opening release is pressed to push the opening half-shaft to rotate, and the roller constraint on the connecting plate 2152 is released. Under the action of the first opening spring 2141, the first insulating pull rod 23 is driven to move to achieve opening. When the first insulating pull rod 23 moves, the indicator plate 52 will move synchronously with the connecting rod 2153 in the same direction. Since the interlocking top rod 51 has only the freedom to slide between the circuit breaker structure 2 and the contactor structure 3, during the movement of the indicator plate 52, the input end of the interlocking top rod 51 and the lower end of the indicator plate 52 will approach each other, so that the output end of the interlocking top rod 51 moves toward the direction close to the electromagnetic operating mechanism 31. When the interlocking top rod 51 moves to the maximum movement direction toward the electromagnetic operating mechanism 31, the output end of the interlocking top rod 51 moves to the maximum movement direction toward the electromagnetic operating mechanism 31. When the circuit breaker structure 2 is in the closed state, the output end of the interlocking top rod 51 presses against the electromagnetic operating mechanism 31 to prevent the second insulating pull rod 33 from closing to realize the interlocking of the circuit breaker structure 2 to the contactor structure 3. When the electromagnetic operating mechanism 31 is normally opened: the electric auxiliary release 600 drives the lower retaining latch 3183 to rotate and disengage, the rotating block 3182 loses balance, the upper retaining latch 3181 disengages the upper retaining roller, and the transmission main shaft 313 reverses to open the switch. The rotating block 3182 is acted upon by the return spring to drive the lower retaining roller back to the front of the lower retaining latch 3183. However, due to the interlocking state, the output end 51 of the interlocking top rod will press against the transmission main shaft 313. Therefore, only when the circuit breaker structure 2 is in the closed state and the interlocking top rod 51 unlocks the electromagnetic operating mechanism 3, the contactor structure 3 can be closed.

[0054] Compared with the technical background, the present invention has the following advantages:

[0055] 1. By integrating the circuit breaker structure 2 and the contactor structure 3, and an insulating phase column 4 and an interlocking mechanism 5 are also provided between the circuit breaker structure 2 and the contactor structure 3, not only the functions of the circuit breaker and the contactor are provided, but also the interlocking and disconnecting functions of the circuit breaker to the contactor can be realized through the interlocking mechanism 5 and the insulating phase column 4, thereby solving the problems of rough protection, small current capacity, difficult mechanical interlocking and high cost in the background technology.

[0056] 2. The starter switch integrates the circuit breaker structure 2 and the contactor structure 3, and its size is similar to that of a vacuum contactor fuse combination appliance or a vacuum circuit breaker, and the size can even be interchangeable. The circuit breaker structure 2 and the contactor structure 3 are each arranged horizontally as a whole and aligned up and down with each other, and the circuit breaker channels 22 are arranged side by side, which has the advantages of simple scheme, small width and compact structure.

[0057] In summary, the present invention has corresponding functions by providing the circuit breaker structure 2 and the contactor structure 3, and an insulating phase column 4 and an interlocking mechanism 5 are provided between the two, which has the advantages of compact structure, diverse functions and low cost.

[0058] The present invention is described above by way of example in conjunction with the accompanying drawings. It is obvious that the specific implementation of the present invention is not limited to the above-mentioned method. As long as various non-substantial improvements are made using the method concept and technical solution of the present invention, or the concept and technical solution of the present invention are directly applied to other occasions without improvement, they are all within the protection scope of the present invention.
