Description

Technical Field

[0001] This utility model relates to the field of outdoor disconnect switch technology, specifically a high-current outdoor disconnect switch. Background Technology

[0002] High-current outdoor disconnect switches are outdoor switchgear used in high-voltage power transmission systems (such as substations and transmission lines). They mainly serve the functions of isolating power supplies, switching operations, and connecting / disconnecting small-current circuits. A disconnect switch is a switch device mainly used for "isolating power supplies, switching operations, and connecting and disconnecting small-current circuits" without arc-extinguishing function. When the disconnect switch is in the open position, there is an insulation distance between the contacts that meets the specified requirements and a clear disconnection mark. When the disconnect switch is in the closed position, it can carry the current under normal circuit conditions and the current under abnormal conditions (such as short circuits) within a specified time.

[0003] For example, a high-current outdoor disconnect switch disclosed in the authorization announcement number CN218414387U includes a mounting base, an insulating support fixedly mounted on the top of the mounting base, an inlet plate fixedly connected to the top of the front insulating support by bolts, an outlet plate fixedly connected to the top of the rear insulating support by bolts, a tripping limit plate fixedly mounted on the top of the outlet plate, and a contact blade rotatably connected to the surface of the tripping limit plate by bolts and nuts;

[0004] Although it achieves the advantage of ensuring full contact between the moving contact and the incoming line plate at all times after the high-current outdoor disconnect switch is closed through the cooperation of the sliding rod, moving contact, spring one, and round plate, thereby improving the safety of the high-current outdoor disconnect switch and preventing power outage due to long-term use, the new type has the advantage of limiting the high-current outdoor disconnect switch after it is closed through the cooperation of the square shell, anti-detachment plate, square plate, spring two, and pull plate. It limits the contact blade after it is closed to prevent it from detaching from the incoming line plate and causing power outage, without affecting normal use;

[0005] However, this does not solve the problem that existing outdoor disconnect switches are generally not easy to rotate to control the opening and closing state, which affects the convenience of controlling the opening and closing of outdoor disconnect switches, makes it difficult to conveniently monitor the state after closing, and can easily lead to untimely power delivery due to improper contact.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a high-current outdoor disconnect switch, comprising a mounting base and left insulating supports. Three sets of equally spaced left insulating supports are mounted on the top of the mounting base. Three sets of equally spaced right insulating supports are mounted on the side of the top of the mounting base away from the left insulating supports. Support frames are mounted on the side of the top of the mounting base closest to the left insulating supports. Hollow boxes are mounted on the top of each support frame.

Three sets of equally spaced insulating sleeves are fitted onto the surface of the rotating shaft. A rotating shaft is movably mounted on the side wall of each insulating sleeve, and an insulating connecting arm is fitted onto the surface of each rotating shaft. A support shaft is movably mounted inside each contact blade holder, and the insulating connecting arms are movably connected to the contact blade holder via the support shaft. A third shaft is movably mounted on the side of the contact blade holder away from the support shaft, and the contact blade holder is movably connected to the inlet plate via the third shaft. A movable shaft is movably mounted at the bottom of each contact blade holder, and an insulating connecting arm is fitted onto the surface of each movable shaft.

[0008] Preferably, a first shaft is movably installed inside the hollow box, and a second shaft is movably installed on the side of the hollow box near the first shaft. A first gear is fitted on the surface of each first shaft, and the first gear is connected to an insulating connecting arm.

[0009] Preferably, the surface of the second shaft is fitted with a second gear, the first gear meshes with the second gear, and a spring is installed inside the top of the hollow box. A rack is installed on the side of the spring away from the hollow box.

[0010] Preferably, each rack meshes with a second gear, a first sensor is installed at the bottom end of each rack, and a second sensor is installed inside the bottom end of each hollow box.

[0011] Preferably, a photovoltaic panel is installed on the top sidewall of the mounting base, an inverter is installed on the top side of the mounting base near the photovoltaic panel, and a battery is installed on the top side of the mounting base near the inverter.

[0012] Preferably, a buzzer is installed on the side wall of the battery, a controller is installed on the top of the mounting base near the battery, and the output end of the photovoltaic panel is electrically connected to the input end of the inverter via wires.

[0013] Preferably, the output terminal of the inverter is electrically connected to the input terminal of the battery, and the output terminal of the battery is electrically connected to the input terminal of the controller.

[0014] Preferably, one end of the controller's output terminal is electrically connected to the first sensor and the second sensor, and the other end of the controller's output terminal is electrically connected to the buzzer.

[0015] Compared with the prior art, the beneficial effects of this utility model are: the outdoor disconnect switch not only realizes the convenient rotation of the outdoor disconnect switch to control the open and closed state, improving the convenience of controlling the opening and closing of the outdoor disconnect switch, but also facilitates the convenient monitoring of the closed state, avoiding the situation of untimely power transmission due to improper contact.

[0016] (1) The insulating handle drives the worm to rotate, the worm drives the worm wheel to rotate, the worm wheel drives the rotating shaft to rotate, the rotating shaft drives the insulating sleeve to rotate, and the insulating sleeve drives the insulating connecting arm to rotate through the rotating shaft. Under the limit support of the third shaft, the insulating connecting arm drives the contact knife frame to rotate around the third shaft at a certain angle through the support shaft, so that the rotation of the contact knife frame presses down onto the surface of the outlet plate. That is, when the high current outdoor disconnect switch is in the closed state, it is energized, realizing the convenient rotation of the outdoor disconnect switch to control the opening and closing state, avoiding the flipping caused by no one operating, which leads to poor contact, and improving the convenience of controlling the opening and closing of the outdoor disconnect switch.

[0017] (2) When the contact knife frame rotates around the third axis, the contact knife frame drives the insulating connecting arm to rotate. Under the movable support of the first axis, the insulating connecting arm drives the first gear to rotate around the first axis. The first gear drives the second gear to rotate. The second gear drives the rack to move. Under the elastic support of the spring, the rack moves downward. When the contact knife frame contacts the outlet plate, the first sensor contacts the second sensor. When the first sensor contacts the second sensor, a signal is sent to the controller, which receives and processes the signal. The controller will turn on the buzzer to alarm and indicate that the switch is closed. This enables convenient monitoring of the closed state of the outdoor disconnect switch and avoids the situation where power transmission is not timely due to improper contact.

[0024] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0025] Please see Figures 1-5This utility model provides an embodiment of a high-current outdoor disconnect switch, comprising a mounting base 1 and a left insulating support 2. Three sets of equally spaced left insulating supports 2 are mounted on the top of the mounting base 1. Three sets of equally spaced right insulating supports 3 are mounted on the side of the top of the mounting base 1 away from the left insulating supports 2. Support frames 4 are mounted on the side of the top of the mounting base 1 closest to the left insulating supports 2. Hollow boxes 5 are mounted on the top of each support frame 4. Contact knife frames 6 are provided on the outside of each left insulating support 2. An inlet plate 7 is mounted on the top of each left insulating support 2. An outlet plate 8 is mounted on the top of each right insulating support 3. A worm gear 10 is movably mounted on the side wall of the mounting base 1. An insulating handle 9 is fitted onto one end of the worm gear 10. A rotating shaft 11 is movably mounted inside the mounting base 1. The rotating shaft 11 extends through the mounting base 1 to its outside. A worm gear 12 is fitted on the surface of the rotating shaft 11 outside the mounting base 1. The worm 10 meshes with the worm gear 12. Three sets of insulating sleeves 13 with equal spacing are fitted on the surface of the rotating shaft 11. A rotating shaft 14 is movably installed on the side wall of each insulating sleeve 13. An insulating connecting arm 15 is fitted on the surface of each rotating shaft 14. A support shaft 16 is movably installed inside each contact knife holder 6. The insulating connecting arms 15 are movably connected to the contact knife holder 6 through the support shaft 16. A third shaft 32 is movably installed on the side of the contact knife holder 6 away from the support shaft 16. The contact knife holder 6 is movably connected to the inlet plate 7 through the third shaft 32. A movable shaft 17 is movably installed at the bottom of each contact knife holder 6. An insulating connecting arm 18 is fitted on the surface of each movable shaft 17.

[0026] When using a high-current outdoor disconnect switch, connect the power inlet line to the inlet board 7 and the power outlet line to the outlet board 8. The high-current outdoor disconnect switch is in the open state. When closing is required, rotate the insulating handle 9. With the support of the mounting base 1, the insulating handle 9 drives the worm gear 10 to rotate. Under the meshing of the worm gear 10 and the worm wheel 12, the worm gear 10 drives the worm wheel 12 to rotate. The worm wheel 12 drives the rotating shaft 11 to rotate. The rotating shaft 11 drives the insulating sleeve 13 to rotate. The insulating sleeve 13 drives the insulating connecting arm 15 to rotate through the rotating shaft 14. Under the limiting support of the third shaft 32... The insulating connecting arm 15 drives the contact blade holder 6 to rotate around the third axis 32 by a certain angle through the support shaft 16, so that the rotation of the contact blade holder 6 presses down onto the surface of the outlet plate 8. That is, when the high current outdoor disconnect switch is in the closed state, it is energized. Because the worm gear 10 and the worm wheel 12 are in an interlocked state, the contact blade holder 6 will not continue to rotate after contacting the outlet plate 8, avoiding the flipping caused by unattended operation and resulting in poor contact. This realizes the convenient rotation of the outdoor disconnect switch to control the opening and closing state, avoids the flipping caused by unattended operation and resulting in poor contact, and improves the convenience of controlling the opening and closing of the outdoor disconnect switch.

[0027] The hollow box 5 has a first shaft 19 movably installed inside, and a second shaft 20 movably installed on the side of the hollow box 5 near the first shaft 19. The surface of the first shaft 19 is fitted with a first gear 21, and the first gear 21 is connected to the insulating connecting arm 18.

[0028] The surface of the second shaft 20 is fitted with a second gear 22. The first gear 21 meshes with the second gear 22. The top of the hollow box 5 is fitted with a spring 23. The side of the spring 23 away from the hollow box 5 is fitted with a rack 24.

[0029] All racks 24 mesh with the second gear 22. The bottom end of each rack 24 is equipped with a first sensor 25. The bottom end of each hollow box 5 is equipped with a second sensor 26. A photovoltaic panel 27 is installed on the top side wall of the mounting base 1. An inverter 31 is installed on the top side of the mounting base 1 near the photovoltaic panel 27. A battery 28 is installed on the top side of the mounting base 1 near the inverter 31.

[0030] A buzzer 30 is installed on the side wall of the battery 28. A controller 29 is installed on the top of the mounting base 1 near the side of the battery 28. The output end of the photovoltaic panel 27 is electrically connected to the input end of the inverter 31 through a wire. The output end of the inverter 31 is electrically connected to the input end of the battery 28. The output end of the battery 28 is electrically connected to the input end of the controller 30.

[0031] One end of the output terminal of the controller 30 is electrically connected to the first sensor 25 and the second sensor 26, and the other end of the output terminal of the controller 30 is electrically connected to the buzzer 29.

[0032] The photovoltaic panel 27 absorbs sunlight, which is converted into current by the inverter 31 and transmitted through wires to the battery 28 for storage. The battery 28 then powers the controller 30, buzzer 29, first sensor 25, and second sensor 26. When the contact blade holder 6 rotates around the third shaft 32, the contact blade holder 6 drives the insulating connecting arm 18 to rotate via the movable shaft 17. Under the movable support of the first shaft 19, the insulating connecting arm 18 drives the first gear 21 to rotate around the first shaft 19. With the meshing of the first gear 21 and the second gear 22, and under the movable support of the second shaft 20, the first gear 21 drives the second gear 22. The switch rotates, and under the meshing of the second gear 22 and the rack 24, the second gear 22 drives the rack 24 to move. Under the elastic support of the spring 23, the rack 24 moves downward. When the contact knife holder 6 and the outlet plate 8 are in contact, the first sensor 25 and the second sensor 26 are in contact. When the first sensor 25 and the second sensor 26 are in contact, a signal is sent to the controller 30, which receives and processes the signal. The controller 30 will then activate the buzzer 29 to provide an alarm indicating that the switch is closed. This enables convenient monitoring of the closed state of the outdoor disconnect switch and avoids untimely power delivery due to improper contact.

[0033] Working principle: The insulating handle 9 drives the worm gear 10 to rotate, which in turn drives the worm wheel 12 to rotate. The worm wheel 12 drives the rotating shaft 11 to rotate, which in turn drives the insulating sleeve 13 to rotate. The insulating sleeve 13, through the rotating shaft 14, drives the insulating connecting arm 15 to rotate. Under the limiting support of the third shaft 32, the insulating connecting arm 15, through the support shaft 16, drives the contact knife holder 6 to rotate a certain angle around the third shaft 32. This causes the contact knife holder 6 to rotate and press down onto the surface of the outlet plate 8. When the high-current outdoor disconnect switch is in the closed state, it is energized. Because the worm gear 10 and the worm wheel 12 are interlocked, the contact knife holder 6 will not continue to rotate after contacting the outlet plate 8. When the contact knife holder 6 rotates around the third shaft 32, the contact knife... The frame 6 drives the insulating connecting arm 18 to rotate. Under the movable support of the first shaft 19, the insulating connecting arm 18 drives the first gear 21 to rotate around the first shaft 19. Under the meshing of the first gear 21 and the second gear 22, and the movable support of the second shaft 20, the second gear 22 drives the rack 24 to move. Under the elastic support of the spring 23, the rack 24 moves downward. When the contact knife frame 6 and the outlet plate 8 are in contact, the first sensor 25 and the second sensor 26 are in contact. When the first sensor 25 and the second sensor 26 are in contact, a signal is sent to the controller 30, which receives and processes the signal. The controller 30 will then activate the buzzer 29 to provide an alarm indicating that the switch is closed, thus completing the operation of the outdoor disconnect switch.
