Description

Technical Field

[0001] The present invention relates to the technical field of switchgear, and in particular to a high-efficiency and environment-friendly disconnecting switchgear. Background Art

[0002] The switchgear is a combination of switchgear and related control, measurement, protection and regulation equipment. Usually, circuit breakers and disconnectors are installed inside the switchgear.

[0003] Usually, when the circuit needs to be repaired, the circuit needs to be disconnected. When the circuit is disconnected, the circuit breaker needs to be disconnected first and then the isolating switch. When the circuit needs to be connected, the isolating switch needs to be closed first and then the circuit breaker. However, during maintenance, the operator may accidentally touch the circuit breaker and the isolating switch, and the disconnection and closing sequence may not meet the standards, resulting in danger. At the same time, the opening and closing of the circuit breaker is realized by connecting the power supply through the coil and cooperating with the electromagnet drive. If the coil fails, the electromagnet cannot be used normally, the circuit breaker cannot be opened and closed normally, and the circuit is difficult to open and close normally. A spring drive mechanism is provided inside the circuit breaker to achieve opening and closing. Some main drive parts in the spring drive mechanism that generate friction for a long time will produce certain wear. When some parts are severely worn, it may affect the normal opening and closing of the circuit breaker. The spring drive mechanism is arranged inside the shell, and it is difficult to detect the wear of the parts in time. The overall safety of the switchgear needs to be further improved.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] The present invention is provided with a detection mechanism. When the circuit breaker is opened and closed, two groups of detection mechanisms can detect whether the locking plate and the retaining block 1 are in place. When the circuit breaker is closed, during the closing process, the early warning locking mechanism detects whether the locking plate is rotated into place. If the closing electromagnet fails, the locking plate can be assisted to rotate into place to assist in closing, and the wear degree of the movable pressure plate can be detected at the same time. When the closing is completed, the early warning locking mechanism can lock the drive shaft 4 to ensure the correct opening and closing sequence of the circuit breaker and the disconnecting switch. During the opening process of the circuit breaker, the detection mechanism can detect whether the retaining block 1 is in place, and when the opening electromagnet fails, it can ensure that the movable connecting plate 1 can be smoothly rotated into place, and the opening is successfully completed, thereby improving the safety of the switchgear. At the same time, the cooperation of the early warning locking mechanism and the auxiliary locking mechanism ensures that the circuit breaker and the disconnecting switch are in the correct order when the circuit is connected and disconnected to avoid the occurrence of dangers caused by accidental touch.

[0022] The present invention is provided with a detection mechanism. When the circuit breaker is opened and closed, the corresponding latch plate and the energy storage holding latch are unlocked by pressing down the closing electromagnet, and the contact between the static contact and the moving contact and the closing of the circuit breaker are realized by the cooperation of the energy storage spring and the connecting rod structure. At the same time, the retaining block 1 and the retaining block 2 and the retaining plate are unlocked by pressing down the opening electromagnet, and the separation of the static contact and the moving contact and the opening of the circuit breaker can be realized by the cooperation of the connecting rod structure and the opening spring. When the closing electromagnet and the opening electromagnet are pressed down, the detection block is driven to move by the cooperation rotating arm, and the trigger switch 1 is detected to reflect whether it is triggered. Check whether the positioning plate and the retaining block are rotated into place. If not, it means that the coil used to connect the closing electromagnet or the opening electromagnet may fail. Subsequently, the early warning locking mechanism is used to assist the positioning plate and the retaining block to rotate into place to ensure that the circuit breaker is opened and closed normally. At the same time, when the circuit is disconnected, it is necessary to ensure the order of disconnecting the circuit breaker first and then disconnecting the isolating switch. When the circuit breaker is opened, the retaining block is rotated into place, the corresponding trigger switch is pressed and triggered, and the isolating switch is unlocked. Then the operator can disconnect the isolating switch to ensure safety when the circuit is disconnected.

[0023] The present invention is provided with an early warning locking mechanism. During the opening and closing process of the circuit breaker, if there is a coil failure and the locking plate and the retaining block 1 are not rotated to the position to complete the unlocking, the early warning locking mechanism detection mechanism is used to rotate and drive the internal frame 1 and the internal frame 2 to adjust to the target angle, and the movable wheel 1 and the movable wheel 2 are extended to the corresponding locking plate and the retaining block 1 and exert a force to assist them to rotate to the position to complete the unlocking to ensure the normal opening and closing of the circuit breaker. At the same time, after the circuit breaker is opened, the movable wheel 3 and the movable wheel 1 are rotated to limit the movable connecting plate 3 and the movable connecting plate 4 to lock the driving shaft 4. When the subsequent circuit needs to be connected and the disconnector is successfully closed, the movable wheel 3 and the movable wheel 1 are unlocked, and then the circuit breaker can be closed normally, so as to ensure that the circuit is closed in the order of first closing the disconnector and then closing the circuit breaker, thereby ensuring the safety of the operation.

[0024] The present invention is provided with a detection positioning component. During daily maintenance, the early warning locking mechanism detection mechanism rotates and drives the movable wheel one, movable wheel two and movable wheel three to rotate to the corresponding movable pressure plate, retaining block one and retaining block two, and controls the movable wheel one, movable wheel two and movable wheel three to extend to the target position, and presses the corresponding inner extension block through the movable connecting plate one, movable connecting plate four and movable connecting plate three, and senses the distance between the inner extension block through the distance sensor. When the distance value is within the normal range, it means that the retaining block one, the movable pressure plate and the retaining block two are not seriously worn. If the distance value exceeds the normal use range, it means that the circuit breaker cannot guarantee normal opening and closing and subsequent holding point locking operations at this time, and maintenance personnel are required to perform inspection and maintenance at this time.

[0025] The present invention is provided with a trigger buffer component. When the circuit is connected, the isolating switch needs to be closed first and then the circuit breaker. If during operation, the operator touches the circuit breaker by mistake, the closing electromagnet is pressed down and contacts the buffer plate. The buffer plate rotates downward. During the rotation of the buffer plate, it first contacts the contact sensor. After the contact, the contact sensor feeds back a contact signal and controls the external prompter to give a prompt. If the operator notices the false touch, the power supply can be disconnected in time, and the closing electromagnet stops pressing down and resets. If the operator does not notice the false touch in time, the prompter continues to be in a prompting state. At the same time, because the movable wheel one and the movable wheel three cooperate with the movable connecting plate four and the movable connecting plate three to limit the drive shaft four, the drive shaft four can be prevented from rotating to prevent the static contact and the moving contact from contacting and closing.

[0026] The present invention is provided with an auxiliary locking mechanism, when the circuit is disconnected, the opening electromagnet is pressed down and driven by the connecting rod structure to unlock the holding block 1 and the holding block 2 with the holding plate. After unlocking, the static contact and the moving contact are separated to disconnect the circuit breaker. When the circuit breaker is disconnected, the holding block 1 rotates to the right position and presses and triggers the corresponding trigger switch 1, and then the limit card block is separated and unlocked from the movable gear 1. The external driving structure can drive the isolation main shaft to rotate and cooperate with the movable gear 1 and the movable rack to press and trigger the trigger switch 3. After the trigger switch 3 is pressed and triggered, the movable wheel 1 and the movable wheel 3 are connected to the movable connecting wheel 1. The connecting plate three, the movable connecting plate four and the driving shaft four are locked. When the circuit is connected, the external driving structure drives the movable gear two to rotate in the opposite direction. The gear teeth of the movable gear two first contact the trigger switch two and press the trigger switch two. Then, the movable wheel one and the movable wheel three are controlled to move and reset to release the lock of the movable connecting plate three and the movable connecting plate four on the driving shaft four. Then, the circuit breaker can be closed to ensure that when the circuit is disconnected, the circuit breaker is disconnected first and then the isolating switch is disconnected. When the circuit is connected, the isolating switch is closed first and then the circuit breaker is closed, so as to ensure the safety of operation. BRIEF DESCRIPTION OF THE DRAWINGS

The moving contact 272 is connected to the driving shaft 26 through a straightening structure, an opening spring and a connecting rod structure. Two sets of detection mechanisms 4 are arranged inside the circuit breaker housing. The detection mechanism 4 can detect whether the retaining block 252 and the positioning plate 251 are in place. An early warning locking mechanism 5 is arranged inside the circuit breaker housing. The early warning locking mechanism 5 can ensure the correct opening and closing sequence of the circuit breaker and the disconnector, and perform an auxiliary locking operation after the circuit breaker is closed.At the same time, it is detected whether the movable pressure plate 261 is in place when the circuit breaker is closed to ensure the safety of the switch equipment.

At the same time, after the circuit breaker is opened, the movable wheel 3 523 and the movable wheel 1 511 are rotated to limit the movable connecting plate 3 263 and the movable connecting plate 4 264 to lock the driving shaft 4 26. When the subsequent circuit needs to be connected and the disconnector is successfully closed, the movable wheel 3 523 and the movable wheel 1 511 are unlocked, and then the circuit breaker can be closed normally, so as to ensure that the circuit is closed in accordance with the order of closing the disconnector first and then closing the circuit breaker, so as to ensure the safety of operation. ;

When the distance value is within the normal range, it means that the retaining block one 252, the movable pressure plate 261 and the retaining block two 262 are not severely worn. If the distance value exceeds the normal use range, it means that the circuit breaker cannot guarantee normal opening and closing and subsequent holding point locking operations at this time, and maintenance personnel are required to perform inspection and maintenance.

[0049] As a technical optimization solution for an efficient and environmentally friendly disconnecting switchgear of the present invention, the driving assembly includes a fixed frame 53, which is fixedly installed inside the circuit breaker housing, and a connecting rack 532 is movably installed on the fixed frame 53, and a driving gear 531 is rotatably installed on one side of the connecting rack 532, and the driving gear 531 and the connecting rack 532 are meshed with each other, and the driving gear 531 is fixedly connected to the movable main shaft 54, and a lifting block 533 is movably installed on the fixed frame 53, and the lifting block 533 is fixedly connected to the connecting rack 532, and the fixed frame 53 is A return spring for connecting the lifting block 533 is fixedly installed, and the lifting block 533 is driven to slide by an electromagnet.

An internal buffer block 234 is movably mounted on the lower pressure block 231, and the internal buffer block 234 is movably connected to the lower pressure block 231 through a spring. A contact sensor 235 is fixedly mounted on the internal buffer block 234, and the contact sensor 235 is electrically connected to the external controller. By providing a trigger buffer component, when the circuit is connected, the isolating switch needs to be closed first and then the circuit breaker. If the operator touches the circuit breaker by mistake during operation, the circuit breaker will be closed first. At this time, the closing electromagnet 21 is pressed down and contacts the buffer plate 233, and the buffer plate 233 rotates downward. During the rotation of the buffer plate 233, it first contacts the contact sensor 235. After the contact, the contact sensor 235 feeds back a contact signal and controls the external prompter to give a prompt. If the operator notices the false touch, the power supply can be disconnected in time, and the closing electromagnet 21 stops pressing down and resets. If the operator does not notice the false touch in time, the prompter continues to be in a prompting state. At the same time, because the movable wheel 1 511 and the movable wheel 3 523 cooperate with the movable connecting plate 4 264 and the movable connecting plate 3 263 to limit the drive shaft 4 26, the drive shaft 4 26 can be prevented from rotating to prevent the static contact 271 from contacting the moving contact 272 to close the circuit.

[0051] As a technical optimization solution for an efficient and environmentally friendly disconnecting switchgear of the present invention, the auxiliary locking mechanism 6 includes a movable gear 2 63, which is fixedly mounted on the isolating main shaft 33, and the movable gear 2 63 is rotatably connected to the mounting frame 31. A movable gear 1 61 is rotatably mounted on the mounting frame 31, and the movable gear 1 61 and the movable gear 2 63 are meshed with each other. A bayonet is provided on the movable gear 1 61, and a limit block 62 is movably mounted on the mounting frame 31.

The trigger switch 2 652 is electrically connected to the external controller. The gear teeth on the movable gear 2 63 can contact the trigger switch 2 652 and trigger the trigger switch 2 652. A trigger switch 3 66 is fixedly installed on the mounting frame 31. The trigger switch 3 66 is electrically connected to the external controller. The device is electrically connected; by providing an auxiliary locking mechanism 6, when the circuit is disconnected, the opening electromagnet 22 is pressed down and driven by the connecting rod structure to unlock the holding block 252 and the holding block 262 and the holding plate 243. After unlocking, the static contact 271 and the moving contact 272 are separated to disconnect the circuit breaker. When the circuit breaker is disconnected, the holding block 252 rotates to the right position and presses the corresponding trigger switch 44, and then the limit card block 62 is separated from the movable gear 61 and unlocked. The isolation main shaft 33 can be driven to rotate through the external drive structure and cooperate with the movable gear 61 and the movable rack 64 to press and trigger the trigger switch 3 66. After the trigger switch 3 66 is pressed and triggered, the movable wheel 1 511 and the movable wheel 3 5 23 locks the movable connecting plate three 263, the movable connecting plate four 264 and the driving shaft four 26. When the circuit is connected, the external driving structure drives the movable gear two 63 to rotate in the opposite direction. The gear teeth of the movable gear two 63 first contact the trigger switch two 652 and press the trigger switch two 652. Then, the movable wheel one 511 and the movable wheel three 523 are controlled to move and reset to release the locking of the movable connecting plate three 263 and the movable connecting plate four 264 on the driving shaft four 26. Then, the circuit breaker can be closed to ensure that when the circuit is disconnected, the circuit breaker is first disconnected and then the isolating switch is disconnected. When the circuit is connected, the isolating switch is first closed and then the circuit breaker is closed, so as to ensure the safety of operation.

[0052] When the present invention is used, when the circuit needs to be disconnected, the circuit breaker needs to be disconnected first and then the isolating switch needs to be disconnected; when the circuit needs to be connected, the isolating switch needs to be closed first and then the circuit breaker needs to be closed;

[0053] When the circuit breaker is opened, the power is turned on, the opening electromagnet 22 is pressed down and cooperates with the pressing block 2 232 and the connecting rod structure to drive the holding block 1 252 to rotate. After the holding block 1 252 rotates to the right position, the holding plate 243 and the two holding points on the holding block 1 252 and the holding block 2 262 are disassembled, and the moving contact 272 is separated from the static contact 271 under the action of the opening spring to realize the opening of the circuit breaker. When the circuit breaker is closed, the power is turned on, the closing electromagnet 21 is pressed down and drives the positioning plate 251 to rotate by cooperating with the pressing block 1 231 and the connecting rod structure. The positioning plate 251 rotates and separates from the energy storage holding latch 242. The cam plate 241 rotates under the action of the energy storage spring and presses the movable pressing plate 261 to rotate, and at the same time cooperates with the connecting rod structure to drive the moving contact 272 to push up and contact with the static contact 271 for closing.

[0054] When disconnecting the circuit, the circuit breaker is first opened, the opening electromagnet 22 is controlled to be pressed down and cooperate with the pressing block 2 232 and the connecting rod structure to drive the holding block 1 252 to rotate. When the holding block 1 252 rotates, the rotating arm 43 can be cooperated to drive the detection block 42 to slide. When the opening electromagnet 22 is normally pressed down and drives the holding block 1 252 to rotate into place, if the holding block 1 252 rotates into place, the detection block 42 can press and trigger the trigger switch 1 44. After the holding block 1 252 rotates into place, the two holding points on the holding plate 243, the holding block 1 252 and the holding block 2 262 are disassembled, and the moving contact 272 is connected with the static contact under the action of the opening spring. The head 271 is separated to realize the opening of the circuit breaker. When the trigger switch 144 is pressed and triggered, the power supply of the electromagnet used to drive the limit block 62 to move is disconnected, and the limit block 62 is reset under the action of the reset spring. The movable gear 1 61 is unlocked, and the isolation main shaft 33 is driven to rotate through the external drive structure to mobilize the isolation knife 32 to be pulled open to disconnect the isolation switch. When the isolation main shaft 33 rotates, the movable gear 2 63 can be driven to rotate and the movable gear 1 61 can be driven to rotate by meshing with the movable gear 1 61. The movable gear 1 61 meshes with the movable gear 2 63. At the same time, when the movable gear 1 61 rotates, it meshes with the movable rack 64 to drive The movable rack 64 drives the rotating block 651 to slide toward the movable gear 2 63 side. After the movable rack 64 slides into place, it contacts the trigger switch 3 66 and triggers the trigger switch 3 66. When the isolating knife 32 is rotated and opened into place, the movable gear 1 61 and the movable gear 2 63 stop rotating. At the same time, the movable rack 64 is positioned. At this time, the trigger switch 2 652 moves to the side of the movable gear 2 63. When the trigger switch 3 66 is pressed and triggered, the power supply of the electromagnet driving the lifting block 533 is turned on. The electromagnet drives the lifting block 533 to slide and drives the driving gear 531 to rotate by meshing with the connecting rack 532. The driving gear 531 rotates When the movable main shaft 54 ​​is driven to rotate, the inner frame 1 51 and the inner frame 2 52 are driven to rotate and adjust the position. When the movable main shaft 54 ​​is rotated to the right position, the electromagnet power supply for driving the movable wheel 3 523 and the movable wheel 1 511 is turned on. The electromagnet drives the movable wheel 3 523 and the movable wheel 1 511 to extend to the corresponding movable connecting plate 4 264 and the movable connecting plate 3 263 to contact them. At this time, the driving shaft 4 26 is limited and locked under the cooperation of the movable connecting plate 3 263, the movable connecting plate 4 264, the movable wheel 1 511 and the movable wheel 3 523. At the same time, the circuit breaker and the isolating switch are disconnected, and the circuit is disconnected;

[0055] When the circuit is overhauled and needs to be connected, close the isolating switch first. At this time, the driving shaft four 26 is locked by the movable connecting plate three 263, the movable connecting plate four 264, the movable wheel one 511 and the movable wheel three 523. The external driving structure drives the movable gear two 63 to rotate in the opposite direction. When the movable gear two 63 rotates in the opposite direction, its gear teeth first contact with the trigger switch two 652 and press the trigger switch two 652. At the same time, the movable gear two 63 and the movable gear one 61 are meshed with each other to drive the movable gear one 61 to rotate and reset. At the same time, the movable gear one 61 and the movable rack 64 are meshed with each other to drive the movable rack 64 to move and reset. After resetting, the limit block 62 is inserted into the movable gear one 61 to limit it. When the trigger switch 2 652 is pressed and triggered and the isolating switch is closed, the movable wheel 1 511 and the movable wheel 3 523 are controlled to move and reset to release the locking of the movable connecting plate 3 263 and the movable connecting plate 4 264 on the driving shaft 4 26, and then the circuit breaker can be closed. When closing, the control is turned on, the closing electromagnet 21 is pressed down and drives the positioning plate 251 to rotate by cooperating with the pressing block 1 231 and the connecting rod structure. The positioning plate 251 rotates and separates from the energy storage holding latch 242. The cam plate 241 rotates under the action of the energy storage spring and presses the movable pressing plate 261 to rotate, and at the same time cooperates with the connecting rod structure to drive the moving contact 272 to push up and contact the static contact 271 to close the circuit.

[0056] When the circuit is connected, it is necessary to close the isolating switch first and then the circuit breaker. If during the operation, the operator touches the circuit breaker by mistake, the closing electromagnet 21 is pressed down and contacts the buffer plate 233, and the buffer plate 233 rotates downward. During the rotation of the buffer plate 233, it first contacts the contact sensor 235. After the contact, the contact sensor 235 feeds back a contact signal and controls the external device prompter to give a prompt. If the operator notices the mistaken touch, the power supply can be disconnected in time, and the closing electromagnet 21 stops pressing down and resets. If the operator does not notice the mistaken touch in time, the prompter continues to be in the prompting state. At the same time, because the movable wheel 1 511 and the movable wheel 3 523 cooperate with the movable connecting plate 4 264 and the movable connecting plate 3 263 to limit the driving shaft 4 26, the driving shaft 4 26 can be prevented from rotating to prevent the static contact 271 from contacting the moving contact 272 to close the switch.

[0057] When the circuit breaker is opened, if the opening electromagnet 22 is controlled to be pressed down to disconnect the circuit breaker, and the coil fails and causes the opening electromagnet 22 to be unable to be pressed down normally, within the specified time, the pressing block 232 is not rotated to the right position, and the corresponding trigger switch 1 44 is not triggered. At this time, the power is turned on, and the electromagnet drives the lifting block 533 to slide and engage with the driving gear 531 through the connecting rack 532 to drive the movable main shaft 54 ​​to rotate. When the movable main shaft 54 ​​rotates to the right position, the control electromagnet drives the extension arm 3 522 and the movable wheel 2 521 to move to the side of the movable connecting plate 1 253 and contact the movable connecting plate 1 253 to apply force to it. The movable connecting plate 1 253 slides upward under the action of the extension arm 3 522, and the two holding points on the retaining plate 243 and the retaining block 1 252 and the retaining block 2 262 are disassembled. The moving contact 272 is separated from the cabinet 17 cabinet 1 under the action of the opening spring, and the circuit breaker is opened.

[0058] When closing the circuit breaker, if the closing electromagnet 21 is controlled to be pressed down to close the circuit breaker, and the coil fails and causes the closing electromagnet 21 to be unable to be pressed down normally, within a limited time, the positioning plate 251 has not rotated to the right position, and the corresponding trigger switch 1 44 has not been triggered. At this time, the power is turned on, and the electromagnet drives the lifting block 533 to slide and engage with the driving gear 531 through the connecting rack 532 to drive the movable main shaft 54 ​​to rotate. When the movable main shaft 54 ​​rotates to the right position, the control electromagnet drives the movable wheel 1 511 to move toward the side of the movable connecting plate 254 and exerts a force on it. The movable connecting plate 254 and the positioning plate 251 rotate upward under the action of the movable wheel 1 511 and are separated and unlocked from the energy storage holding latch 242. The cam plate 241 rotates under the action of the energy storage spring and presses the movable pressure plate 261 to rotate, and at the same time cooperates with the connecting rod structure to drive the movable contact 272 to push up and contact the static contact 271 to close the circuit.

[0059] During routine maintenance of the switchgear, the electromagnet is controlled to drive the lifting block 533 to move and the movable main shaft 54 ​​is driven to rotate by meshing with the connecting rack 532 and the driving gear 531. When the movable main shaft 54 ​​rotates to the position of the movable wheel 1 511 corresponding to the movable connecting plate 3 263, the movable wheel 1 511 is controlled to extend toward the side of the movable connecting plate 3 263. When the movable wheel 1 511 is extended to the set position, the movable connecting plate 3 263 contacts and squeezes the inner extension block 516 on the movable wheel 1 511, and the inner extension block 516 moves toward the inner side of the inner sleeve 517. At the same time, the distance sensor 518 can sense the distance between the inner extension block 516. If the feedback distance value is within the normal range, it means that the position of the movable pressure plate 261 is accurate, and there is no problem that the cam plate 241 and the movable pressure plate 261 are in contact and friction, causing the wear thereof to exceed the normal use range. If the feedback value is not within the normal use range, it means that the cam plate 241 and the movable pressure plate 261 are in contact and friction, causing the wear thereof to exceed the normal use range.

[0060] The control electromagnet drives the lifting block 533 to move and drives the movable main shaft 54 ​​to rotate through the connecting rack 532 and the driving gear 531 to mesh with each other. When the movable main shaft 54 ​​rotates to the position where the movable wheel 2 521 and the movable wheel 3 523 correspond to the movable connecting plate 1 253 and the movable connecting plate 4 264, the control electromagnet drives the movable wheel 2 521 and the movable wheel 3 523 to slide and extend to the set position. When the movable wheel 2 521 and the movable wheel 3 523 are extended to the set position, the movable connecting plate 1 253 and the movable connecting plate 4 264 can squeeze the inner extension block 516 on the movable wheel 2 521 and the movable wheel 3 523. The distance sensor 518 senses the distance between the inner extension block 516 and feeds back the distance value. If the fed back distance value is within the normal range, it means that the position of the holding block 1 252 and the holding block 262 is accurate. If the fed back value is not within the normal use range, it means that the contact and friction between the holding block 1 252 and the holding block 262 and the holding plate 243 causes their wear to be serious beyond the normal use range.
