Description

Technical Field

[0001] This invention relates to the field of disconnecting switch technology, specifically to an intelligent disconnecting switch for high-voltage lines. Background Technology

[0002] Intelligent disconnect switches are based on traditional disconnect switches and integrate advanced technologies such as sensors, power electronics, the Internet of Things, and data processing. They not only retain the core functions of traditional disconnect switches, such as forming a "visible disconnection point," isolating power supply, and ensuring maintenance safety, but also have the functions of holographic status perception and real-time monitoring, precise control and intelligent fault diagnosis, high integration and strong environmental adaptability. They play an important role in power supply, such as large-scale power grid security and defense systems and intelligent dispatch systems.

[0003] The patent application with application number CN201920734248.9 mentions "an intelligent disconnect switch". This patent disconnects the power to the appliance with the lowest power consumption to avoid equipment failure or abnormality caused by insufficient power supply. At the same time, by classifying the appliance with the lowest power consumption, the power disconnection time is determined to ensure that the disconnected equipment will not fail due to power failure, thereby ensuring the stable operation of each appliance under low voltage or unstable voltage conditions.

[0004] However, in the current market, many high-voltage disconnect switches have stationary contacts with the opening facing upwards or poorly sealed structures. During long-term outdoor operation, rainwater and other debris can easily accumulate on the outside of the stationary contacts. With the high temperature and pressure during subsequent use, an insulating film will form, which cannot be removed by rainwater washing alone. This increases the resistance at the connection, affecting the circuit connection and increasing heat generation, thus increasing the probability of damage. Summary of the Invention

With the high temperature and pressure during subsequent use, an insulating film will form, which cannot be removed by rainwater washing alone. This increases the resistance at the connection, affects the circuit connection, and also increases the heat generation, thereby increasing the probability of damage.

[0010] According to the above technical solution, the aluminum alloy heat-conducting plate has grooves evenly distributed on its outer side, and the air supply hole is close to the aluminum alloy heat-conducting plate.

[0011] According to the above technical solution, the supporting insulator is fixedly installed on the side of the mechanism base away from the arc-extinguishing chamber, and a connecting piece is installed on the top of the arc-extinguishing chamber.

[0012] According to the above technical solution, the base of the mechanism is equipped with a lubrication disconnection component, which includes a geared motor; A geared motor is installed on one side of the base of the mechanism. The output shaft of the geared motor passes through one side of the base and is connected to a shaft. A fixed top rod is welded to the shaft corresponding to the conductive rod. One end of the fixed top rod is connected to an insulating seat through a rotating shaft. A support cylinder is installed on the top of the insulating seat. A lubrication tank is installed inside the support cylinder. A press pump is installed on the top of the lubrication tank. A movable top cover is slidably sleeved on the top of the support cylinder. Limiting guide rings are symmetrically welded to the bottom of the movable top cover.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. Equipped with a safety switch assembly, during the closing of the isolating switch, the edge of the cleaning scraper first contacts the stationary contact, the cleaning spring is compressed and contracted, and the cleaning scraper slides along the cleaning hole. At this time, the replacement scraper will scrape off the debris on the outside of the stationary contact, remove the insulation layer, and expose the conductive part until the replacement scraper is engaged in the limit slot. The conductive block in the contact hole is pushed by the conductive spring and tightly fits against the outside of the stationary contact. With the help of the contact sleeve, it can better conduct electricity and connect the circuit, avoiding the problem of increased resistance at the connection point, which would affect the circuit connection and increase heat generation, thereby increasing the probability of damage. During the use of the disconnect switch, when the wind blows through the air-collecting tube, the wind enters the air-collecting tube. Because the bottom of the air-collecting tube and the air outlet are smaller, the wind speed increases due to the slit effect. The air is accelerated and blows over the outside of the conductive rod. The aluminum alloy heat-conducting plate increases the heat exchange area and cools the conductive rod to prevent it from overheating during use. If the cooling capacity of the air-collecting duct is insufficient to cool the conductive rod, the temperature of the conductive rod will continue to rise. When the temperature exceeds 80°C, the temperature will be transferred to the low-temperature expanding graphite block inside the fixed duct through the bottom support plate. The low-temperature expanding graphite block will begin to expand slowly. If the temperature continues to rise, the low-temperature expanding graphite block will also expand faster, lifting the blind tube and pushing the contact sleeve at the end of the conductive rod to disengage from the stationary contact. Meanwhile, the synchronizing rod will push the conductive rod to simultaneously push all three conductive rods to disconnect the circuit, ensuring the safety of the high-voltage line.

[0017] 2. Equipped with a lubrication disconnection component, when the circuit needs to be disconnected, if the rotating parts are corroded and difficult to rotate, the geared motor is repeatedly started to loosen the connection between the fixed top rod and the insulating seat. The fixed top rod and the insulating seat are pushed, the movable top cover is squeezed, and the top of the press pump is squeezed. The lubricating oil inside the lubrication tank will flow simultaneously through the main delivery pipe and the auxiliary delivery pipe. The bottom nozzle at the end of the auxiliary delivery pipe sprays lubricating oil to the connection between the fixed top rod and the insulating seat. The main delivery pipe, through the conveying through the ring delivery pipe, sprays lubricating oil with the straight nozzle to the connection between the conductive rod, the conductive seat, and the insulating top seat. The curved nozzle sprays lubricating oil to the connection between the contact sleeve and the stationary contact, making all connections lubricated and loose. At this time, the isolating switch can be disconnected, preventing the problem of the circuit being difficult to disconnect due to corrosion or other conditions. There is no need for manual disconnection, making the operation safer and more reliable. In summary, the lubrication disconnect component sprays lubricating oil at each connection point to ensure smooth closure of the disconnect switch. At the same time, a lubricating oil film is also formed at the stationary contact. However, the safety switch component scrapes off the lubricating oil film when closing the circuit to prevent the lubricating oil film from affecting the circuit connection. Furthermore, if the corrosion is severe and the lubrication disconnect component alone cannot disconnect in time, or if the geared motor cannot start, the circuit can also be disconnected by the lifting blind tube and the low-temperature expansion graphite block of the safety switch component. The combined use of the two components greatly improves the safety of the circuit. Attached Figure Description

[0024] The base 1 of the mechanism is equipped with a lubrication disconnection assembly 5, which includes a reduction motor 501, a shaft 502, a fixed top rod 503, an insulating seat 504, a support cylinder 505, a lubrication tank 506, a press pump 507, a movable top cover 508, a limiting guide ring 509, a limiting screw 510, an insulating top seat 511, a main delivery pipe 512, an annular delivery pipe 513, a straight nozzle 514, a curved nozzle 515, a secondary delivery pipe 516, a bottom nozzle 517, a C-type clip 518, and a sealing ring 519.

The annular delivery pipe 513 is installed on the bottom surface of the top baffle 422.

[0025] The working principle and usage process of this invention are as follows: Before installing the disconnect switch, a lubrication tank 506 filled with lubricating oil is placed inside the support cylinder 505. A press pump 507 is installed on the top of the lubrication tank 506. A movable top cover 508 is sleeved on the top of the support cylinder 505. The limiting screw 510 passes through the limiting guide ring 509. The limiting screw 510 is connected to the support cylinder 505 through a screw hole. At this time, the limiting screw 510 is at the bottom of the limiting guide ring 509, ensuring that the limiting guide ring 509 can slide along the limiting screw 510. After installing the disconnect switch in its designated location and completing the wiring, remotely control the geared motor 501 to rotate the shaft 502. This rotation sequentially pulls the conductive rod 401 through the fixed top rod 503, insulating seat 504, support cylinder 505, limit guide ring 509, movable top cover 508, and insulating top seat 511, causing the contact sleeve 402 to engage with the outside of the stationary contact 411. During this process, the edge of the cleaning scraper 408 first contacts the stationary contact 411, compressing and contracting the cleaning spring 410, and the cleaning scraper 408 moves along the cleaning path. When the cleaning hole 407 slides, the replacement scraper 409 will scrape away the debris on the outside of the stationary contact 411, remove the insulating layer, and expose the conductive part until the replacement scraper 409 is engaged in the limiting slot 415. The conductive block 405 in the contact hole 404 is pushed by the conductive spring 406 and tightly fits against the outside of the stationary contact 411. In conjunction with the contact sleeve 402, it can better conduct electricity and connect the circuit. During maintenance, the wear of the replacement scraper 409 should be checked. If the replacement scraper 409 is worn too much, it should be replaced in time. During the use of the disconnect switch, when the wind blows through the air-collecting tube 423, the wind enters the air-collecting tube 423. Because the bottom end of the air-collecting tube 423 and the air outlet 424 become smaller, the wind speed increases due to the slit effect. The air is accelerated and blows over the outside of the conductive rod 401. The aluminum alloy heat-conducting plate 426 increases the heat exchange area and cools the conductive rod 401 to prevent the conductive rod 401 from overheating during use. When the circuit needs to be disconnected, the geared motor 501 is started, driving the conductive rod 401 to rotate. The contact sleeve 402 is forced to disengage from the contact hole 404. During this process, if there is no rust or jamming in any of the rotating parts, the conductive rod 401 will be directly pushed to disconnect the circuit. If the rotating parts are rusted and difficult to rotate, the geared motor 501 is started repeatedly, causing the connection between the fixed top rod 503 and the insulating seat 504 to loosen. The fixed top rod 503 and the insulating seat 504 are pushed, the movable top cover 508 is squeezed, and the top of the press pump 507 squeezes. The lubricating oil inside the lubrication tank 506 will be delivered through the main delivery pipe 512 and the auxiliary delivery pipe. Simultaneously, the conveying pipe 516 flows, and the bottom nozzle 517 at the end of the auxiliary conveying pipe 516 sprays lubricating oil to the connection between the fixed top rod 503 and the insulating seat 504. The main conveying pipe 512 is conveyed through the annular conveying pipe 513. The straight nozzle 514 sprays lubricating oil to the connection between the conductive rod 401, the conductive seat 3, and the insulating top seat 511. The curved nozzle 515 sprays lubricating oil to the connection between the contact sleeve 402 and the stationary contact 411, so that each connection is lubricated and loosened. At this time, the disconnecting switch can be disconnected to prevent the circuit from being difficult to disconnect due to rust or other conditions. There is no need to disconnect manually, and the operation is safer and more reliable. If the cooling capacity of the air-collecting duct 423 is insufficient to cool down the conductive rod 401, the temperature of the conductive rod 401 will continue to rise. When the temperature exceeds 80°C, the temperature will be transferred to the low-temperature expanding graphite block 419 in the fixed conduit 416 through the bottom support plate 414. The low-temperature expanding graphite block 419 will begin to expand slowly. If the temperature continues to rise, the low-temperature expanding graphite block 419 will also expand faster, lifting the blind tube 418 and pushing the contact sleeve 402 at the end of the conductive rod 401 to separate from the stationary contact 411. Meanwhile, the synchronizing rod 421 will push the conductive rod 401 to simultaneously push all three conductive rods 401 to disconnect the circuit, ensuring the safety of the high-voltage line.
