Description

Technical Field

[0001] The present invention relates to the technical field of circuit breakers, and more particularly to an air-insulated circuit breaker for an outdoor switch cabinet. Background Art

[0002] A circuit breaker refers to a switching device that can close, carry, and interrupt the current under normal circuit conditions and can close, carry, and interrupt the current under abnormal circuit conditions within a specified time. Circuit breakers are divided into high-voltage circuit breakers and low-voltage circuit breakers according to their application scope. Circuit breakers can be used to distribute electric energy, start asynchronous motors infrequently, protect power supply lines and motors, etc. When serious overload, short circuit, undervoltage and other faults occur, the circuit can be automatically cut off, and no parts need to be changed after interrupting the fault current; Today's circuit breakers have the advantages of small size, light weight, being suitable for frequent operation, and no need for maintenance of arc extinguishing. They are widely used in the distribution network. Nowadays, an airtight insulating cylinder made of ceramics, glass or glass-ceramics is provided inside the circuit breaker. This insulating cylinder can isolate the arc generated during power-off to ensure its safety during power-off; When today's circuit breakers are used outdoors, they will be affected by the external environment. When they work in cold seasons, if icing occurs at the connection between the knife switch and the insulator, the knife switch and the insulator will be frozen at this time. When they are frozen and it is necessary to trip and cut off the power, the tripping operation cannot be carried out in time, which will cause damage to the electrical equipment when it continues to work; Since it is currently impossible to accurately detect whether the circuit breaker is frozen during operation, it is impossible to repair the frozen circuit breaker in time; When the vacuum arc extinguishing chamber inside the circuit breaker performs the power-off operation, the contacts inside it separate during power-off, and high temperature will be generated when the contacts separate. Although it is isolated by ceramics, the temperature still rises rapidly, so its damage frequency is relatively high. Summary of the Invention

[0003] In order to overcome the above-mentioned defects of the prior art, an embodiment of the present invention provides an air-insulated circuit breaker for an outdoor switch cabinet to solve the technical problems raised in the background art.

[0004] To achieve the above object, the present invention provides the following technical solution: an air-insulated circuit breaker for an outdoor switch box, including an installation table, on one side of the top of the installation table, an insulator is fixedly connected, and on the other side of the top of the installation table, a vacuum interrupter is fixedly connected. A knife switch is movably connected to the side of the vacuum interrupter close to the installation table, and the bottom end of the side of the knife switch away from the vacuum interrupter is connected to the top of the insulator. A gas mechanism is fixedly connected to the side of the installation table away from the insulator, a shunt mechanism is fixedly connected to the side of the gas mechanism, a cooling component is fixedly connected to the top end of the side of the shunt mechanism away from the gas mechanism, and an anti-freezing component is fixedly connected to the bottom end of the side of the shunt mechanism away from the gas mechanism; The gas mechanism includes a gas box filled with gas. A sealing plate is movably connected inside the gas box, and the sealing plate seals the inside of the gas box. Four corners of the inside of the gas box close to the side of the shunt mechanism are all fixedly connected with first electromagnets. Four corners of the inside of the gas box away from the first electromagnets are all movably connected with support springs, and both sides of the support springs are in contact with the inside of the gas box and the side of the sealing plate.

[0005] Further, an installation frame is fixedly connected to the side of the installation table away from the gas mechanism. A smart camera is fixedly connected to the top end of the installation frame. A control terminal is fixedly connected to the side of the installation table away from the smart camera. A temperature collector is fixedly connected to the top of the installation table. The smart camera collects image data information at the connection between the knife switch and the insulator and sends it to the control terminal.

[0006] Further, the control terminal receives the image data information sent by the smart camera and calculates the proportional characteristic value F. The calculation formula of the proportional characteristic value F is , where B is the perimeter of the area where the knife switch contacts the insulator, and A is the area of the area where the knife switch contacts the insulator. When the control terminal detects that the proportional characteristic value F changes, it controls the gas mechanism to work.

[0007] Further, four corners of the side of the sealing plate away from the first electromagnets are all fixedly connected with limit cylinders. A limit rod is movably connected inside the limit cylinders, and the side of the limit rod away from the limit cylinders is fixedly connected to the inside of the gas box. The limit cylinders and the limit rods are located inside the support springs, and the side of the gas box away from the support springs is communicated with the shunt mechanism.

[0008] Further, the shunt mechanism includes a gas passage for receiving the gas in the gas mechanism. A first shunt is fixedly connected to the top end of the side of the gas passage away from the gas mechanism, and a second shunt is fixedly connected to the bottom end of the side of the gas passage away from the gas mechanism. The bottom end of the first shunt is connected to the top end of the second shunt.

[0009] Further, a rotating plate is movably connected to the connection between the first shunt and the second shunt. A fixed shaft is movably connected inside the rotating plate. Both sides of the fixed shaft are fixedly connected to the inside of the gas channel. A second electromagnet is fixedly connected to the top of the gas channel near the first shunt, and the top of the rotating plate is in contact with the bottom of the second electromagnet.

[0010] Further, the anti-freezing assembly includes a heating channel that receives the gas from the second shunt in the shunt mechanism. A lower channel is fixedly connected to the side of the heating channel. A first connection channel is fixedly connected to the side of the lower channel away from the heating channel. A gas nozzle is fixedly connected to the side of the first connection channel away from the lower channel. The air outlet of the gas nozzle is located at the connection between the knife switch and the insulator.

[0011] Further, the cooling component includes an upper channel that receives the gas from the first shunt in the shunt mechanism. A second connection channel is fixedly connected to the top of the upper channel. An acceleration outlet is fixedly connected to the side of the second connection channel. The air outlet of the acceleration outlet is located at the side of the vacuum interrupter.

[0012] Technical effects and advantages of the present invention: When there is a possibility of freezing between the knife switch and the insulator in the present invention, the first electromagnet is powered off. When the first electromagnet is powered off, the support spring causes the sealing plate to reset. At this time, the sealing plate moves towards the gas channel, so the gas in the gas tank is pressed into the gas channel. The gas entering the gas channel is heated again through the heating channel and then blown to the connection between the knife switch and the insulator through the gas nozzle, preventing the knife switch and the insulator from freezing together. In the present invention, an intelligent camera collects images of the connection between the knife switch and the insulator, and the intelligent camera sends the collected images to the control terminal. The control terminal receives the image data and calculates the proportional characteristic value F. When the control terminal detects a change in the proportional characteristic value F, the control terminal controls the operation of the gas mechanism and the anti-freezing assembly to heat and thaw the connection between the knife switch and the insulator, preventing the knife switch and the insulator from freezing. When a power-off and disconnection occurs in the present invention, the first electromagnet and the second electromagnet will automatically power off. After the first electromagnet is powered off, gas is sent into the gas channel. After the second electromagnet is powered off, the magnetic attraction force between it and the rotating plate disappears, and the rotating plate rotates around the fixed shaft under the action of gravity. At this time, the gas channel is connected to the first shunt, and the gas will be sent to the cooling component through the first shunt. The gas in the cooling component is blown to the side of the vacuum interrupter through the acceleration outlet to cool the vacuum interrupter. Description of the drawings

Detailed implementation manners

[0022] Next, the technical solutions in the present invention will be clearly and completely described in conjunction with the drawings in the present invention. In addition, the forms of each structure described in the following embodiments are only examples. An air-insulated circuit breaker for an outdoor switch cabinet involved in the present invention is not limited to the structures described in the following embodiments. All other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the scope of protection of the present invention.

[0023] Refer to Figure 1 And Figure 2, the present invention provides an air-insulated circuit breaker for an outdoor switch box, including an installation platform 1. On one side of the top of the installation platform 1, an insulator 4 is fixedly connected, and on the other side of the top of the installation platform 1, a vacuum interrupter 2 is fixedly connected. A knife switch 3 is movably connected to the side of the vacuum interrupter 2 close to the installation platform 1. The bottom end of the side of the knife switch 3 far from the vacuum interrupter 2 is connected to the top of the insulator 4. A gas mechanism 5 is fixedly connected to the side of the installation platform 1 far from the insulator 4. A shunt mechanism 6 is fixedly connected to the side of the gas mechanism 5. At the top end of the side of the shunt mechanism 6 far from the gas mechanism 5, a cooling component 8 is fixedly connected, and at the bottom end of the side of the shunt mechanism 6 far from the gas mechanism 5, an anti-freezing component 7 is fixedly connected. An installation frame 9 is fixedly connected to the side of the installation platform 1 far from the gas mechanism 5. A smart camera 10 is fixedly connected to the top of the installation frame 9. A control terminal 12 is fixedly connected to the side of the installation platform 1 far from the smart camera 10. A temperature collector 11 is fixedly connected to the top of the installation platform 1. The smart camera 10 collects the image data information at the connection between the knife switch 3 and the insulator 4 and sends it to the control terminal 12.

[0024] In the embodiment of the present application, the smart camera 10 will collect the image data at the connection between the knife switch 3 and the insulator 4. Therefore, when there are changes at the connection of the smart camera 10, it can be detected and processed in time, avoiding the knife switch 3 and the insulator 4 from being frozen for a long time and unable to perform normal power-off protection work.

[0025] Refer to Figure 1 And Figure 2 , the control terminal 12 receives the image data information sent by the smart camera 10 and calculates the proportional characteristic value F. The calculation formula of the proportional characteristic value F is , where B is the perimeter of the area where the knife switch 3 contacts the insulator 4, and A is the area of the area where the knife switch 3 contacts the insulator 4. When the control terminal 12 detects that the proportional characteristic value F changes, it controls the gas mechanism 5 to work.

[0026] In the embodiment of the present application, after the knife switch 3 and the insulator 4 are closed, at this time, the connection between the knife switch 3 and the insulator 4 is static, so the knife switch 3 and the insulator 4 will not change in form. When the knife switch 3 and the insulator 4 are frozen, ice will condense on the surfaces of the knife switch 3 and the insulator 4, and their forms will change, that is, the proportional characteristic value F changes. Therefore, when the proportional characteristic value F changes, heating and de-icing work is carried out.

[0027] Refer to Figure 3 , Figure 4 And Figure 5, the gas mechanism 5 includes a gas tank 501 filled with gas. A sealing plate 502 is movably connected inside the gas tank 501. The sealing plate 502 seals the inside of the gas tank 501. At the four corners of the gas tank 501 near the side of the shunt mechanism 6, first electromagnets 503 are fixedly connected. At the four corners of the inside of the gas tank 501 far from the first electromagnets 503, support springs 504 are movably connected. The two sides of the support springs 504 are in contact with the inside of the gas tank 501 and the side of the sealing plate 502. At the four corners of the side of the sealing plate 502 far from the first electromagnets 503, limiting cylinders 505 are fixedly connected. A limiting rod 506 is movably connected inside the limiting cylinders 505. The side of the limiting rod 506 far from the limiting cylinders 505 is fixedly connected to the inside of the gas tank 501. The limiting cylinders 505 and the limiting rod 506 are located inside the support springs 504. The side of the gas tank 501 far from the support springs 504 is communicated with the shunt mechanism 6.

[0028] In the embodiment of the present application, when the first electromagnet 503 is powered on, there is a magnetic repulsive force between the first electromagnet 503 and the sealing plate 502. At this time, the sealing plate 502 moves away from the first electromagnet 503 and compresses the support spring 504. When the support spring 504 is compressed, the limiting rod 506 is completely located inside the limiting cylinder 505. When thawing is required, the first electromagnet 503 is powered off. Therefore, the magnetic repulsive force between the sealing plate 502 and the first electromagnet 503 disappears. At this time, when the support spring 504 resets, it will cause the sealing plate 502 to move towards the first electromagnet 503 and come into contact with the first electromagnet 503 after moving. At this time, part of the limiting rod 506 is still located inside the limiting cylinder 505, playing a limiting role. And when the sealing plate 502 moves, it will automatically push the gas into the shunt mechanism 6. Since the gas is pushed out when the first electromagnet 503 is powered off, even if there is a power failure due to a fault, the gas mechanism 5 can still push out the gas. In addition, it should be noted that the first electromagnet 503 resets ten minutes after being powered off to give time for the gas to be pushed out.

[0029] Refer to Figure 5 And Figure 6 , the shunt mechanism 6 includes a gas passage 601 for receiving the gas in the gas mechanism 5. At the top of the side of the gas passage 601 far from the gas mechanism 5, a first shunt 602 is fixedly connected. And at the bottom of the side of the gas passage 601 far from the gas mechanism 5, a second shunt 603 is fixedly connected. The bottom end of the first shunt 602 is fixedly connected to the top end of the second shunt 603. A rotating plate 605 is movably connected at the connection of the first shunt 602 and the second shunt 603. A fixed shaft 604 is movably connected inside the rotating plate 605. The two sides of the fixed shaft 604 are fixedly connected to the inside of the gas passage 601. At the top of the gas passage 601 near the first shunt 602, a second electromagnet 606 is fixedly connected. The top end of the rotating plate 605 is in contact with the bottom end of the second electromagnet 606.

[0030] In the embodiment of the present application, when the rotating plate 605 contacts the second electromagnet 606, the rotating plate 605 seals the first shunt 602. At this time, the gas will only enter the second shunt 603. When the circuit is broken, the second electromagnet 606 is powered off. At this time, the magnetic suction force between the second electromagnet 606 and the rotating plate 605 disappears. Therefore, the rotating plate 605 will rotate downward around the fixed shaft 604. When the rotating plate 605 rotates, it will seal the second shunt 603. At this time, the gas will enter the first shunt 602. The first shunt 602 is connected to the cooling component 8, and the second shunt 603 is connected to the anti-freezing component 7. The present application can supply gas to the anti-freezing component 7 or the cooling component 8 respectively under different circumstances to cope with different situations. And when powered off, the rotating plate 605 will automatically drop under the action of gravity and seal the second shunt 603. The gas will only enter the first shunt 602 and enter the cooling component 8 to perform the cooling work of the vacuum interrupter 2.

[0031] Referring to Figure 1 With Figure 7 , the anti-freezing component 7 includes a heating channel 701 that receives the gas from the second shunt 603 in the receiving shunt mechanism 6. A lower channel 702 is fixedly connected to the side of the heating channel 701. A first connection channel 703 is fixedly connected to the side of the lower channel 702 away from the heating channel 701. A gas nozzle 704 is fixedly connected to the side of the first connection channel 703 away from the lower channel 702. The gas outlet of the gas nozzle 704 is located at the connection between the knife switch 3 and the insulator 4.

[0032] In the embodiment of the present application, when the gas enters the heating channel 701, the heating channel 701 will perform heating work. At this time, the gas is heated. The heated gas is discharged from the gas nozzle 704 and is discharged to the connection between the knife switch 3 and the insulator 4. At this time, the ice formed when the knife switch 3 and the insulator 4 are frozen will be melted, ensuring that the knife switch 3 and the insulator 4 can perform normal closing and opening operations.

[0033] Referring to Figure 8 , the cooling component 8 includes an upper channel 801 that receives the gas from the first shunt 602 in the receiving shunt mechanism 6. A second connection channel 802 is fixedly connected to the top of the upper channel 801. An acceleration outlet 803 is fixedly connected to the side of the second connection channel 802. The gas outlet of the acceleration outlet 803 is located on the side of the vacuum interrupter 2.

[0034] In the embodiment of the present application, the gas entering the upper channel 801 will be blown to the side of the vacuum interrupter 2 through the second connection channel 802. The vacuum interrupter 2 will generate high temperature during arc isolation when the circuit is broken. The gas blown to the side of the vacuum interrupter 2 will cool the vacuum interrupter 2, and it can automatically perform the cooling work when powered off. When the closing operation is completed for troubleshooting, the sealing plate 502 and the rotating plate 605 are powered on again to reset the equipment.

[0035] Working principle of the present invention: During operation, the intelligent camera 10 collects image data at the connection between the knife switch 3 and the insulator 4, and sends the collected image data information to the control terminal 12. The control terminal 12 receives the image data and calculates the proportional characteristic value F. When the control terminal 12 detects a change in the proportional characteristic value F, there is a possibility of freezing between the knife switch 3 and the insulator 4 at this time. The control terminal 12 controls the first electromagnet 503 to cut off the power. After the first electromagnet 503 cuts off the power, the originally compressed support spring 504 will reset. When the support spring 504 resets, it drives the sealing plate 502 to move towards the gas channel 601, and at this time, the gas in the gas tank 501 will be pushed into the gas channel 601; When the gas enters the inside of the gas channel 601, the rotating plate 605 seals the first shunt 602. The gas in the gas channel 601 will enter the second shunt 603 and pass through the second shunt 603 into the heating channel 701. When the first electromagnet 503 cuts off the power, the heating channel 701 will start heating work. Therefore, the gas entering the heating channel 701 will be heated. The heated air enters the lower channel 702 and the first connection channel 703 and is discharged through the gas nozzle 704. The discharged gas will blow to the connection between the knife switch 3 and the insulator 4 to prevent the knife switch 3 and the insulator 4 from freezing. When the first electromagnet 503 is powered on again ten minutes after cutting off the power, a magnetic repulsive force is generated with the sealing plate 502, resetting the sealing plate 502 and compressing the support spring 504. At this time, the side of the gas tank 501 close to the gas channel 601 is filled with gas again; When the temperature collector 11 detects that the external temperature is relatively high, the control terminal 12 controls the first electromagnet 503 to cut off the power again. At this time, when the gas passes through the heating channel 701, the heating channel 701 will not perform heating work. Therefore, the gas will directly blow to the connection between the knife switch 3 and the insulator 4 for cooling work; When problems occur during the operation of electrical equipment, such as short circuits, the knife switch 3 and the insulator 4 will separate from each other to trip. After they separate, the overall equipment is powered off, and all the equipment inside that requires power drive stops. Since the sealing plate 502 is made of ferromagnetic material, the first electromagnet 503 is powered off, and the compressed support spring 504 resets to push the gas into the gas channel 601. When the second electromagnet 606 is powered off, the magnetic attraction force between it and the rotating plate 605 disappears. Therefore, under the action of gravity, the rotating plate 605 will rotate downward around the fixed shaft 604. After the rotating plate 605 rotates downward, it contacts the bottom end inside the gas channel 601. Therefore, the rotating plate 605 seals the second shunt 603. At this time, the gas will enter the first shunt 602 and pass through the first shunt 602 into the upper channel 801. The gas entering the upper channel 801 will be blown to the side of the vacuum interrupter 2 through the second connection channel 802. The vacuum interrupter 2 will generate high temperature during arc isolation when breaking the circuit. The gas blown to the side of the vacuum interrupter 2 will cool the vacuum interrupter 2, and it can automatically perform the cooling work when powered off. When troubleshooting and completing the closing, the sealing plate 502 and the rotating plate 605 are powered on again to reset the equipment.

[0036] Finally: The above are only the preferred embodiments of the present invention and are not used to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
