Description

Technical Field

[0001] This invention pertains to power supplies for substations, specifically to an integrated remote switching power supply for substations. Background Technology

[0002] With the diversification of power communication network services and the exponential increase in the number of services, reliable communication network transmission has become the foundation for the reliable operation of the power grid, given the current trend of unmanned and intelligent substation construction. Ensuring the stable operation of various equipment is of paramount importance.

[0003] During the operation of substation equipment, equipment failures and downtimes occur frequently. Often, maintenance personnel can resolve the issue by simply powering off and restarting the equipment upon arrival on-site. This is especially true for substation monitoring equipment, where the harsh operating environment of cameras can trigger protection mechanisms at high temperatures, causing cameras to disconnect. Reconnecting the power usually resolves the problem. Summary of the Invention

[0052] The following detailed description of the integrated remote switching power supply for substations of the present invention, in conjunction with the accompanying drawings, is not intended to limit the scope of the invention.

[0053] The substation integrated remote power supply includes a front-end open enclosure 1, a panel 2, several air switches 3, a switching device 5, an integrated circuit board 6, and a power module 7.

[0054] The panel 2 is installed over the front opening of the enclosure 1. The panel 2 has several drainage holes 201. Air switches 3 are fixed inside the enclosure 1, and the operating handle 301 of the air switches 3 protrudes to the outside of the panel 2 through the drainage holes 201. The drainage holes 201 on the panel 2 are arranged in parallel at intervals. The number of drainage holes 201 is greater than or equal to the number of air switches 3. The number of air switches 3 depends on how many devices or monitoring / detection instruments within the substation are powered by the integrated remote switching power supply. The number of air switches 3 installed corresponds to the number of power lines required. If the number of air switches 3 installed is less than the number of drainage holes 201, a sealing cover is installed at the drainage holes 201 where no air switches 3 are installed.

[0055] A card plate 202 is fixed at the upper and lower ends of the inner side of the leakage hole 201, and the air switch 3 is clamped between the two card plates 202.

[0056] The power module 7 is provided with a number of terminals, the number of which is the same as the number of exposed holes 201. The number of terminals is greater than or equal to the number of air switches 3. The air switches 3 and the terminals of the power module 7 are electrically connected via ribbon cables. Connecting the air switches 3 and the power module 7 via ribbon cables is more convenient and faster, and also facilitates wiring, making the interior of the housing 1 neater.

[0057] The power supply inside the substation supplies power to the power module 7 via a plug-in cable, and the power module 7 supplies power to the air switch 3 via a ribbon cable.

[0058] Inside the housing 1, a placement plate 101 is fixed, and partitions 102 are provided on the placement plate 101. Air switches 3 are placed on the placement plate 101, positioned between the partitions 102, thus facilitating alignment with the leakage holes 201 on the panel 2. All air switches 3 are arranged horizontally at intervals, and the rear ends of all air switches 3 are inserted into the same insertion plate 4. Vertically arranged fixing plates 103 protrude from the inner wall of the housing 1, and both ends of the insertion plate 4 are fixedly connected to the fixing plates 103 by bolts.

[0059] The cutting device 5 is fixedly connected to the panel 2 by bolts. The cutting device 5 corresponds to the air switch 3 one by one. Since the cutting device 5 can be disassembled, the number of cutting devices 5 can be installed as many as there are air switches 3, thus realizing modularity.

[0060] The switching device 5 includes a housing 501, a closing device 502, and a driving device. The housing 501 is open on the side facing the air switch 3. The closing device 502 is rotatably disposed inside the housing 501. The driving device drives the closing device 502 to rotate.

[0061] The control handle 301 is located inside the housing 501. The closing device 502 includes several blades 5021. When the control handle 301 is in the position where the air switch 3 is de-energized, one of the blades 5021 is located below the control handle 301 and in contact with the control handle 301.

[0062] To facilitate observation of the relative positions of the blade 5021 and the control handle 301 during installation, the upper and front ends of the housing 501 can be open.

[0063] When the air switch 3 trips, the control handle 301 moves down, and the drive device drives the closing device 502 to rotate. The blade 502, which is in contact with the control handle 301, rotates, pushing the control handle 301 upward, thereby closing the air switch 3 again and supplying power to the load. A protruding plate 50211 is fixed to the end of the blade 502 facing the control handle 301 to prevent the blade 502 from slipping and being unable to push the control handle 301.

[0064] The closing device 502 includes several blades 5021, an intermediate shaft 5022, and a gear ring 5025.

[0065] Several blades 5021 are arranged in a ring array around the axis of the intermediate shaft 5022, and the ends of the blades 5021 are fixedly connected to the circumferential surface of the intermediate shaft 5022.

[0066] The two ends of the intermediate shaft 5022 are inserted into the inner walls on both sides of the housing 501. The gear ring 5025 is connected to one end of the intermediate shaft 5022. The rotation of the gear ring 5025 drives the intermediate shaft 5022 to rotate. The drive device is connected to the gear ring 5025.

[0067] The drive unit can be an electric motor, with a drive gear fixed at the output end of the motor, which meshes with the gear ring 5025.

[0068] In this embodiment, three blades 5021 are evenly distributed on the intermediate shaft 5022. The intermediate shaft 5022 has a slot arranged coaxially inside, and a cross rod 5023 is inserted into the slot. The cross-sectional shape inside the slot is the same as the cross-sectional shape of the cross rod 5023. Therefore, the rotation of the cross rod 5023 can drive the intermediate shaft 5022 to rotate.

[0069] At least one end of the cross rod 5023 protrudes outside the intermediate shaft 5022. An overrunning clutch 5024 is fitted onto the protruding end of the cross rod 5023. The overrunning clutch 5024 is a ratchet overrunning clutch or a roller overrunning clutch.

[0070] The cross rod 5023 is fixedly connected to the inner ring of the overrunning clutch 5024, and the toothed ring 5025 is sleeved on the outer ring of the overrunning clutch 5024 and fixedly connected to the outer ring. In this way, when the toothed ring 5025 rotates in one direction, it can drive the inner ring of the overrunning clutch 5024 and the cross rod 5023 to rotate. When the toothed ring 5025 rotates in the other direction, it cannot drive the cross rod 5023 to rotate.

[0071] The drive unit includes a vertically arranged rack 503, which meshes with a gear ring 5025. The lower end of the rack 503 is fixedly connected to the top end of the telescopic rod of the telescopic mechanism 504. The telescopic mechanism 504 is fixedly connected to the outer wall of the housing 501. The telescopic mechanism 504 is electrically connected to a terminal block 5041 fixed on the outer wall of the housing 501. The terminal block 5041 is electrically connected to the integrated circuit board 6 via a pluggable ribbon cable.

[0072] When the telescopic mechanism 504 is powered on, the telescopic rod extends and pushes the rack 503 upward. The rack 503 drives the toothed ring 5025 to rotate, rotating 120° each time. After the telescopic mechanism 504 is powered off, the rack 503 retracts. During the retraction process, the toothed ring 5025 cannot drive the cross rod 5023 to rotate.

[0073] The terminals connecting the integrated circuit board 6 to the telescopic mechanism 504 are located on the outside of the bottom or side of the housing 1. The telescopic mechanism 504 is an electric cylinder or an electromagnet.

[0074] To prevent the closing device 502 from rotating under inertia and causing inaccurate positioning, both ends of the cross rod 5023 are exposed outside the intermediate shaft 5022.

[0075] One end of the cross rod 5023 is fitted with an overrunning clutch 5024, and the other end is fitted with a rotating shaft 5026. The rotating shaft 5026 is located outside the housing 501, and a damping ring 5027 is fitted outside the rotating shaft 5026.

[0076] The damping ring 5027 is covered by a fixed sleeve 507. The outer circumferential surface of the damping ring 5027 abuts against the inner wall of the fixed sleeve 507. The fixed sleeve 507 is fixedly connected to the outer wall of the housing 501. The damping ring 5027 can be a rubber ring.

[0077] A lower position sensor 505 and an upper position sensor 506 are fixed on the inner wall of the housing 501. The lower position sensor 505 corresponds to the position of the control handle 301 when the air switch 3 is de-energized, and the upper position sensor 506 corresponds to the position of the control handle 301 when the air switch 3 is energized.

[0078] Both the lower position sensor 505 and the upper position sensor 506 are electrically connected to the integrated circuit board 6 via ribbon cable. In this embodiment, both the lower position sensor 505 and the upper position sensor 506 are photoelectric through-beam sensors. The position of the control receiver 301 is detected by the lower position sensor 505 and the upper position sensor 506, thereby determining the state of the air switch 3.

[0079] The panel 2 is equipped with a plurality of indicator lights 10, and each indicator light 10 corresponds one-to-one with an air switch 3.

[0080] The indicator light 10 is electrically connected to the integrated circuit board 6. The indicator light 10 has three states: red, green, and off. When the corresponding air switch 3 is powered on, the light is green; when the air switch 3 is powered off, the light is red; and when the air switch 3 is not installed, the light is off.

[0081] The lower position sensor 505 and the upper position sensor 506 transmit the detection signal to the integrated circuit board 6, and the integrated circuit board 6 feeds back the corresponding information to the indicator light 10.

[0082] The power module 7 is electrically connected to the integrated circuit board 6, which is equipped with an industrial control chip, a rectifier, a voltage regulator, a remote transmission module, and a signal receiving module. The structure, circuit diagram, and layout of the integrated circuit board 6 all adopt existing technologies.

[0083] Since multiple circuit breakers 8 are powered by the same power module 7, the power module 7 generates heat during operation. Combined with the heat dissipated by the integrated circuit board 6, this raises the internal temperature of the enclosure 1. If heat is not dissipated in time, it can easily lead to aging of the wiring or even a fire. In this embodiment, a heat sink 9 is fixed to the back of the enclosure 1 using thermally conductive adhesive and screws. The heat sink 9 has several open-ended heat dissipation ducts 901 in the middle. The lower opening of the heat dissipation duct 901 is larger than the upper opening, creating a chimney effect inside. Heat from inside the enclosure 1 is transferred to the heat sink 9, some of which diffuses into the air, while some heats the air inside the heat dissipation ducts 901. The heated air inside the heat dissipation ducts 901 rises. Because the heat dissipation ducts 901 are narrower at the top and wider at the bottom, the airflow gradually increases as it rises, creating a suction effect. This draws in fresh air from the lower inlet of the heat dissipation ducts 901, further carrying away heat and achieving a cooling effect inside the enclosure 1.

[0084] To enhance heat dissipation, the two opposite ends of the enclosure 1 are equipped with an air intake grille at one end and an exhaust fan at the other, allowing for forced cooling by turning on the exhaust fan. A filter made of electrostatic electret air filtration material can be added to the air intake grille to adsorb dust from the air.

[0085] Meanwhile, a fire extinguishing device 8 is fixed below the top surface of the box 1. The fire extinguishing device 8 has a cavity inside, which is filled with fire extinguishing material. The fire extinguishing material can be a mixture of foam fire extinguishing agent, dry powder fire extinguishing agent and high-pressure gas, or high-pressure gas of carbon dioxide or nitrogen.

[0086] The fire extinguishing device 8 is provided with a feeding pipe 801 that is connected to the cavity. The feeding pipe 801 is equipped with a one-way valve, and the fire extinguishing substance can only be injected into the fire extinguishing device 8 through the feeding pipe 801.

[0087] The bottom surface of the fire extinguishing device 8 is equipped with a discharge control device 802 with the opening facing downwards.

[0088] The discharge control device 802 includes a vertically arranged discharge pipe 8021, a horizontally arranged control pipe 8022, a piston 8023, a spring 8024, and a controller 8025.

[0089] The upper end of the discharge pipe 8021 is connected through the cavity of the fire extinguishing device 8. The control pipe 8022 intersects and is connected through the discharge pipe 8021, and the axes of the control pipe 8022 and the discharge pipe 8021 are perpendicular to each other. One end of the control pipe 8022 is open, and a coaxially arranged limiting ring 80221 is fixed on the inner wall of the open end.

[0090] Piston 8023 is slidably disposed inside control tube 8022. Piston 8023 has a through hole 80231 arranged vertically along its axis. A spring 8024 is disposed between piston 8023 and the end face of control tube 8022. Under the push of spring 8024, one end of piston 8023 contacts spring 8024, and the other end contacts limiting ring 80221. Through hole 80231 is staggered with the inner cavity of discharge tube 8021 and is located between limiting ring 80221 and discharge tube 8021.

[0091] The telescopic rod 80251 of the controller 8025 passes through the control tube 8022. The telescopic rod 80251 is arranged coaxially with the piston 8023, and the end face of the telescopic rod 80251 contacts the end face of the piston 8023.

[0092] After the fire starts inside the box, the controller 8025 controls the extension rod 80251 to extend and retract, pushing the piston 8023 so that the through hole 80231 is connected to the discharge pipe 8021. The extinguishing material inside the fire extinguishing device 8 is sprayed out through the discharge pipe 8021 to extinguish the fire inside the box 1.

[0093] The controller 8025 can be electrically controlled. When using electrical control, a sensor needs to be added inside the housing 1, and then the sensor and the controller 8025 are electrically connected to the integrated circuit board 6. However, in the event of a fire, the sensor, connecting lines, etc., may be burned, and the controller 8025 will not be able to receive control signals, causing the fire extinguishing device 8 to fail.

[0094] Therefore, in this embodiment, the controller 8025 uses a temperature-controlled bulb. After the internal temperature of the housing 1 rises, the temperature-controlled bulb is heated, and then the telescopic rod 80251 is extended. As long as the temperature rises, the temperature-controlled bulb will activate, thus making it more stable and preventing the fire extinguishing device 8 from failing.

[0095] In order to adjust the distance between the controller 8025 (i.e., the temperature bulb) and the control tube 8022, and thus adjust the temperature when the piston 8023 is pushed, the discharge temperature of the discharge control device 802 can be set.

[0096] A connecting plate 8026 is fixed above the temperature bulb. The connecting plate 8026 has a T-shaped slide groove, which is fitted onto a T-shaped slide rail 8027. The length of the T-shaped slide rail 8027 is greater than the length of the connecting plate 8026, and the length direction of the T-shaped slide rail 8027 is parallel to the axis of the control tube 8022.

[0097] The connecting plate 8026 is provided with a threaded hole perpendicular to the T-shaped slide rail 8027. The threaded hole is connected to the T-shaped slide groove. The threaded hole is connected to a bolt 8028. Tightening the bolt 8028 will fix the connecting plate 8026 in place.

[0098] When in use, configure the same number of air switches 3 according to the number of devices that need to be remotely switched, and then electrically connect the air switches 3 to the load devices and the power module 7.

[0099] After installing the air switch 3, fix the panel 2 to the housing 1, and then configure an equal number of switching devices 5. Cover the control handle 301 of the air switch 3 with the switching device 5 and fix it to the panel 2.

[0100] When a circuit breaker 3 trips, the lower position sensor 505 on the corresponding switching device 5 detects the position information of the control handle 301 and then transmits the signal to the integrated circuit board 6. The industrial control chip on the integrated circuit board 6 controls the telescopic mechanism 504 of the switching device 5 to move, which drives the blade 5021 to rotate through the gear ring 5025, pushing the control handle 301 up and making the circuit breaker 3 work again.

[0101] At the same time, the remote transmission module on integrated circuit board 6 transmits this information to the main control center of the power supply company's operation and maintenance department, or to the mobile APP of relevant personnel, for marking.

[0102] If a circuit breaker 3 closes and then trips again, and the number of trips reaches a threshold, the integrated circuit board 6 will no longer control the corresponding telescopic mechanism 504 and will report the fault to the main control center of the operation and maintenance department via remote transmission.

[0103] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
