DETAILED DESCRIPTION

[0033] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0034] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0035] Secondly, the term "one embodiment" or "embodiment" herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in various places throughout this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive of other embodiments. Example 1

[0036] Reference Figures 1 to 6 , which is the first embodiment of the present invention, provides an electric operating device for a high-voltage disconnector. The electric operating device for the high-voltage disconnector includes a switch assembly 100, including a support base 101. A rotating rod 105 is rotatably connected to the support base 101. A driving sleeve 106 is fixed to the end of the rotating rod 105. A driving plate 107 is fixed to the surface of the driving sleeve 106. By moving the driving plate 107, the rotating rod 105 can be driven to rotate through the driving sleeve 106, so that the rotating rod 105 drives the knife of the high-voltage disconnector to open and close.

[0037] The operating assembly 200 is arranged on one side of the drive plate 107 and includes a splitter 201, including a support shell 2011 arranged on one side of the drive plate 107. The support shell 2011 is provided with mounting holes at both ends for fixed installation so that the support shell 2011 does not move relative to the support base 101, thereby providing a stable working environment for the support shell 2011. A screw rod 2012 is rotatably connected to the support shell 2011. The end of the screw rod 2012 can be connected to a power source, such as the output end of a servo motor, to control the rotation of the screw rod 2012. A driving block 2013 is rotatably connected to the surface of the screw rod 2012 through a thread. The driving block 2013 itself slides in the support shell 2011. When the screw rod 2012 rotates, it can drive the driving block 2013 to move horizontally in the support shell 2011.

[0038] A connecting plate 2014 is fixed to the top of the driving block 2013, a first spring 2015 is fixed to one side of the connecting plate 2014, and a connecting block 2016 is fixed to the other end of the first spring 2015. A spring cover is also fixed to one side of the connecting plate 2014 to prevent the first spring 2015 from bending when compressed. The first spring 2015 is currently in a normal state. A moving seat 2017 is fixed to the bottom of the connecting block 2016, and limiting strips 2018 are fixed on both sides of the moving seat 2017. The limiting strips 2018 slide in the support shell 2011, so that the moving seat 2017 can move stably horizontally in the support shell 2011. A driving rod 2019 is fixed to one side of the connecting block 2016, and the driving rod 2019 slides in the driving plate 107.

[0039] In the current state shown in the figure, by driving the screw rod 2012 to rotate, the screw rod 2012 drives the driving block 2013 to move, so that the driving block 2013 drives the connecting plate 2014 to compress the first spring 2015, so that the first spring 2015 has a thrust on the connecting block 2016. When the first spring 2015 is compressed to a certain extent, the limit on the movable seat 2017 is released, so that the connecting block 2016 drives the driving plate 107 to move quickly through the driving rod 2019, thereby causing the rotating rod 105 to rotate, thereby causing the knife of the high-voltage disconnector to separate. Example 2

[0040] Reference Figures 8 to 11 , which is the second embodiment of the present invention, and this embodiment is based on the previous embodiment.

[0041] Specifically, the operating assembly 200 also includes a limiter 202 arranged in the support shell 2011, including a first plug-in block 2021 that slides in the support shell 2011, a second spring 2022 is provided in the first plug-in block 2021, the other end of the second spring 2022 is fixed to the inner wall of the support shell 2011, the second spring 2022 is currently in a normal state, a slot 2017-1 is provided on the surface of the movable seat 2017, the end of the first plug-in block 2021 can be inserted into the slot 2017-1, the end of the first plug-in block 2021 is provided with an inclined surface, and the first spring 2015 pulls the movable seat 2017 to make the movable seat 2017 move. The movable seat 2017 moves to the current position. At this time, the movable seat 2017 squeezes the inclined surface of the end of the first plug block 2021, so that the first plug block 2021 moves into the support shell 2011. At this time, the second spring 2022 is squeezed. When the movable seat 2017 drives the slot 2017-1 to move to the side of the end of the first plug block 2021, under the reset elastic force of the second spring 2022, the end of the first plug block 2021 is inserted into the slot 2017-1, and one side limits the movable seat 2017, thereby indirectly limiting the drive plate 107, so that the knife of the high-voltage disconnector is in a closed state.

[0042] Specifically, the limit member 202 also includes a release rod 2023 that slides in the support shell 2011, a support plate 2024 is fixed to the surface of the release rod 2023, a third spring 2025 is fixed to one side of the support plate 2024, and the other end of the third spring 2025 is fixed to the inner wall of the support shell 2011. The third spring 2025 is currently in a stretched state, a first through slot 2021-1 is opened in the first plug block 2021, and the end of the release rod 2023 is located in the first through slot 2021-1.

[0043] By moving the driving block 2013 toward the release rod 2023 and squeezing the release rod 2023, the release rod 2023 can be moved toward the first plug block 2021, so that the inclined surface of the end of the release rod 2023 is squeezed against the first through slot 2021-1, so that the first plug block 2021 moves into the support shell 2011, so that the first plug block 2021 is away from the slot 2017-1, and the limit on the movable seat 2017 is released. During the movement of the driving block 2013, the first spring 2015 will be compressed, so that the first spring 2015 has a strong reset elastic force. Through the push of the first spring 2015, the movable seat 2017 can drive the driving plate 107 to move, so that the knife of the high-voltage disconnector can be opened.

[0044] Specifically, the limiting member 202 also includes a second plug block 2026 that slides in the support shell 2011, and a fourth spring 2027 is provided in the second plug block 2026. The other end of the fourth spring 2027 is fixed to the inner wall of the fourth spring 2027 of the support shell 2011. The fourth spring 2027 is currently in a compressed state. A second through groove 2026-1 is provided in the second plug block 2026, and a pull rod 2028 slides in the support shell 2011. The pull rod 2028 slides in the second through groove 2026-1 to squeeze the second plug block 2026, so that the second plug block 2026 is in the current position. A vertical plate 2029 is fixed on the surface of the pull rod 2028, and a fifth spring 20210 is fixed on one side of the vertical plate 2029. The other end of the fifth spring 20210 is fixed in the support shell 2011, and the fifth spring 20210 is currently in a stretched state.

[0045] When the movable seat 2017 is located on one side of the second plug-in block 2026, the end of the second plug-in block 2026 can be inserted into the slot 2017-1, so that the movable seat 2017 is positioned, and the knife of the high-voltage disconnector is in the open state.

[0046] At this time, the driving block 2013 is moved, so that the driving block 2013 stretches the first spring 2015. As the driving block 2013 moves, the driving block 2013 will squeeze the end of the pull rod 2028, as shown in the figure, so that the pull rod 2028 stretches the fifth spring 20210. In the process of the pull rod 2028 moving, the pull rod 2028 will squeeze the second through groove 2026-1 of the second plug block 2026, thereby driving the second plug block 2026 to slide into the support shell 2011, thereby releasing the limit on the moving seat 2017. Under the pulling force of the first spring 2015, the moving seat 2017 moves quickly to the current state shown in the figure, so that the knife of the high-voltage disconnector is in a closed state. Example 3

[0047] Reference Figures 1 to 11 , which is the third embodiment of the present invention, is based on the first two embodiments.

[0048] Specifically, the operating assembly 200 also includes a reset member 203, including a reset block 2031 that slides in the support shell 2011, and a clamping block 2032 is connected to the reset block 2031 through a rotating shaft. A sixth spring 2033 is fixed to the bottom of the clamping block 2032, and the sixth spring 2033 is currently in a normal state. The other end of the sixth spring 2033 is fixed to the inner wall of the reset block 2031, and a seventh spring 2034 is fixed to one side of the reset block 2031. The seventh spring 2034 is fixed to the inner wall of the support shell 2011, and the seventh spring 2034 is currently in a stretched state and is used to pull the reset block 2031 to move.

[0049] When the reset block 2031 is pulled by the seventh spring 2034, the reset block 2031 can push the movable seat 2017 through the clamping block 2032, so that the movable seat 2017 drives the driving plate 107 to move, so that the knife of the high-voltage disconnect switch can be quickly opened without the need for the screw rod 2012 to rotate a large number of circles to drive the driving block 2013 to move, and then the first spring 2015 pushes the movable seat 2017, so that the knife of the high-voltage disconnect switch can be quickly opened in an emergency.

[0050] Specifically, the reset member 203 also includes a third plug-in block 2035 that slides in the support shell 2011, and an eighth spring 2036 is fixed in the third plug-in block 2035. The eighth spring 2036 is currently in a normal state. The other end of the eighth spring 2036 is fixed to the inner wall of the support shell 2011. A slot 2031-1 is provided on the surface of the reset block 2031, and the end of the third plug-in block 2035 is inserted into the slot 2031-1, thereby limiting the reset block 2031 so that the reset block 2031 will not move under the pulling force of the seventh spring 2034.

[0051] By moving the end of the third inserting block 2035 out of the slot 2031 - 1 , the reset block 2031 can be quickly moved under the pulling force of the seventh spring 2034 .

[0052] Specifically, the reset member 203 further includes a pull column 2037 fixed in the first plug block 2021 and the third plug block 2035, the pull column 2037 slides in the support shell 2011, a movable plate 2038 is provided on one side of the support shell 2011, the movable plate 2038 slides on the surfaces of the two pull columns 2037, a ninth spring 2039 is fixed on one side of the movable plate 2038, the ninth spring 2039 is fixed to the inner wall of the support shell 2011, the ninth spring 2039 is currently in a normal state, an electromagnet 20310 is fixed on the support shell 2011, the electromagnet 20310 is a prior art, and when the electromagnet 20310 is energized, the electromagnet 20310 can generate a strong magnetic force to move the movable plate 2038. The plate 2038 is adsorbed, so that the movable plate 2038 moves toward the electromagnet 20310, so that the movable plate 2038 drives the two pull columns 2037 to move synchronously, so that the two pull columns 2037 pull the first plug block 2021 and the third plug block 2035 respectively, thereby releasing the limit on the movable seat 2017 and the reset block 2031. At this time, the pulling force of the seventh spring 2034 can make the reset block 2031 push the movable seat 2017 through the card block 2032, so that the movable seat 2017 drives the drive plate 107 to move, so that the knife of the high-voltage disconnector can be quickly opened, so that the circuit connection can be quickly disconnected in an emergency.

[0053] Specifically, the operating assembly 200 also includes a force storage member 204 arranged on one side of the reset block 2031, including a pull rod 2041 fixed on one side of the reset block 2031, and a support frame 2042 is fixed to the bottom of the pull rod 2041. The support frame 2042 slides on the bottom of the support shell 2011. Through the setting of the support frame 2042, the pull rod 2041 can be supported so that the pull rod 2041 can move stably. By pulling the pull rod 2041, the reset block 2031 can be driven to move to the current position. During this process, the seventh spring 2034 can be stretched, so that the seventh spring 2034 can store force.

[0054] Specifically, the force storage member 204 also includes a card plate 2043 hinged at the end of the pull bar 2041, and an elastic sheet 2044 is provided on the top of the card plate 2043 and the pull bar 2041. The card plate 2043 can be moved upward by the reset elastic force of the elastic sheet 2044, so that the card plate 2043 is moved to the same horizontal state as the pull bar 2041. A limiting plate 2045 is fixed on the top of the card plate 2043. When the card plate 2043 moves to the same horizontal state as the pull bar 2041, the limiting plate 2045 will fall on the top of the pull bar 2041, thereby limiting the card plate 2043, so that the card plate 2043 can no longer move upward. Drive columns 2046 are fixed on both sides of the card plate 2043, two guide plates 2047 are fixed on the inner wall of the support shell 2011, and a drive groove 2013-1 is provided at the bottom of the drive block 2013.

[0055] The driving block 2013 can drive the card plate 2043 to move through the driving slot 2013-1, so that the card plate 2043 pulls the pull bar 2041, thereby moving the reset block 2031 to the current position;

[0056] During this process, as the driving block 2013 approaches the current position, the guide plate 2047 will squeeze the driving column 2046, so that the driving column 2046 drives the card plate 2043 to move downward, thereby making the card plate 2043 away from the driving slot 2013-1, so that the driving block 2013 cannot drive the card plate 2043 to move, and at the same time the reset block 2031 is limited by the third plug block 2035 and can stay stably in the current state.

[0057] Specifically, the switch assembly 100 further includes a static end insulator 102 fixed on the top of the support base 101. There are three groups of static end insulators 102, each group has two. A conductive mechanism is provided inside the static end insulators 102. Each group of static end insulators 102 is provided with a knife 103. The knife 103 is hinged to the contact at the end of one of the static end insulators 102 and clamped on the contact surface of the other static end insulator 102, so that the circuit of the two static end insulators 102 in a group is conductive. Each knife A moving end insulator 104 is also hinged on 103. The moving end insulator 104 is an insulator and does not conduct electricity. The other end of the moving end insulator 104 is hinged to the rotating rod 105. In the current state shown in the figure, by rotating the rotating rod 105, the moving end insulator 104 can be moved upward, thereby making the moving end insulator 104 away from one of the static end insulators 102, thereby disconnecting the circuit. The switch assembly 100 is a prior art, and those skilled in the art should be clearly aware of its working principle, which will not be described here.

[0058] During use, when the circuit shown in the current figure needs to be disconnected, the screw rod 2012 drives the driving block 2013 to move toward the moving seat 2017, thereby compressing the first spring 2015. When the driving block 2013 moves to the side of the release rod 2023, the release rod 2023 can be pushed, so that the release rod 2023 moves toward the first plug-in block 2021, so that the inclined surface of the end of the release rod 2023 presses against the first through groove 2021-1, so that the first plug-in block 2021 moves into the support shell 2011, thereby An insert block 2021 moves away from the slot 2017-1, releasing the limit on the movable base 2017. Through the push of the first spring 2015, the movable base 2017 can drive the driving plate 107 to move, so that the knife of the high-voltage disconnector can be quickly opened. As the movable base 2017 moves, when the movable base 2017 moves to the side of the second insert block 2026, the end of the second insert block 2026 can be inserted into the slot 2017-1, so that the movable base 2017 is positioned, and the knife of the high-voltage disconnector remains in the open state.

[0059] When the circuit needs to be closed, the screw rod 2012 rotates in the opposite direction, driving the driving block 2013 away from the moving seat 2017, so that the first spring 2015 is stretched. At this time, the first spring 2015 has a strong pulling force on the moving seat 2017. When the driving block 2013 moves quickly to the current position, the pull rod 2028 can be pushed so that the pull rod 2028 squeezes the second through groove 2026-1 of the second plug block 2026, thereby driving the second plug block 2026 to slide into the support shell 2011, thereby releasing the limit on the moving seat 2017. Under the pulling force of the first spring 2015, the moving seat 2017 moves quickly to the current illustrated state, so that the knife switch of the high-voltage disconnector is in a closed state.

[0060] When the circuit needs to be disconnected due to an emergency, the electromagnet 20310 is energized, so that the electromagnet 20310 generates a strong magnetic force, which adsorbs the movable plate 2038 and moves the movable plate 2038 toward the electromagnet 20310, so that the movable plate 2038 drives the two pull columns 2037 to move synchronously, so that the two pull columns 2037 pull the first plug block 2021 and the third plug block 2035 respectively, thereby releasing the limit on the movable seat 2017 and the reset block 2031. At this time, the tension of the seventh spring 2034 can make the reset block 2031 push the movable seat 2017 through the card block 2032, so that the movable seat 2017 drives the drive plate 107 to move, so that the knife of the high-voltage disconnector can be quickly opened, so that the circuit connection can be quickly disconnected in an emergency.

[0061] During the process of the driving block 2013 moving to close the circuit again, the card plate 2043 can be driven to move through the driving slot 2013-1, so that the card plate 2043 pulls the pull bar 2041, thereby moving the reset block 2031 to the current position again, thereby resetting the reset block 2031, so that the emergency mechanism can be reset remotely without manual on-site operation.
