Description

Technical Field

[0001] The present invention relates to the technical field of power transmission and distribution equipment, and in particular to a one-button sequential control double confirmation device for an isolating switch. Background Art

[0002] One-button sequential control is an operation mode for substation gate operation, which can realize the prefabrication of operation project software. The modular construction of operation tasks, automatic identification of equipment status, and automatic sequential execution of operation processes are conducive to comprehensively improving operation efficiency, reducing operation risks, and improving emergency response capabilities. Based on the modification of the existing manual operation mechanism, the existing manual operation mechanism is modified into a one-button sequential control operation. In the process of large-scale modification of the power grid, on the one hand, the original equipment should be fully utilized, and the normal use of the original transmission line should not be affected during the modification process.

[0003] The existing improvement scheme arranges a control circuit, connects the control circuit to the motor in the high-voltage disconnector operating mechanism, and remotely controls the forward and reverse rotation and stop of the motor through the control circuit to realize the opening or closing operation of the disconnector. The opening or closing of the disconnector can be controlled by remotely controlling the forward or reverse rotation time of the motor. In this way, the rotation time of the motor is controlled by a remote program, and then the number of circles of the motor is controlled, thereby controlling the rotation angle of the high-voltage disconnector knife. The problem with this control method is that the control is not accurate, and there is no way to verify whether the knife has actually rotated to the right position, that is, the motor rotates to perform the closing operation. After the motor stops rotating, the knife of the high-voltage disconnector may not actually be in a completely closed state. Such a control method is prone to failures such as lax closing or incomplete opening.

[0004] In summary, there is an urgent need for a one-button sequential control double confirmation device for an isolating switch to solve or at least partially solve the problems existing in the prior art. Summary of the invention

[0005] The object of the present invention is to provide a one-button sequential control double confirmation device for an isolating switch, which aims to solve the problem of incomplete opening or loose closing in the prior art without affecting the normal operation of the original line. The specific technical solution is as follows:

[0006] A one-button sequential control double confirmation device for an isolating switch comprises a bracket, a first sensor, a first toggle assembly, a second sensor and a second toggle assembly, wherein the bracket is fixedly connected to a housing of an operating mechanism, the first sensor and the second sensor are both detachably connected to the bracket, the first sensor and the second sensor are distributed up and down, the first toggle assembly and the second toggle assembly are both detachably connected to a joystick of the operating mechanism, and the first toggle assembly is arranged correspondingly to the first sensor so that the first toggle assembly triggers the first sensor to work or stop when the joystick of the operating mechanism rotates, and the second toggle assembly is arranged correspondingly to the second sensor so that the first toggle assembly triggers the first sensor to work or stop when the joystick of the operating mechanism rotates, and the first toggle assembly and the second toggle assembly are arranged at an angle to each other.

[0009] Preferably, the first toggle assembly further comprises a pad block, which is placed between the first mounting block and the first contact and pressure block to adjust the position of the first contact and pressure block in the height direction.

[0010] Preferably, the first toggle assembly further includes a locking screw, a threaded hole is provided on the first locking block, the locking screw is threadedly connected to the threaded hole, and the locking screw is pressed against the operating rod of the operating mechanism.

[0011] Preferably, it also includes an angle control component, the angle control component includes a pointer and a fourth fastener, the second toggle component includes a second mounting block, the pointer is fastened to the second mounting block by the fourth fastener, the pointer is arranged toward the first mounting block, and an angle scale line is provided on the side of the first mounting block close to the pointer.

[0015] The application of the technical solution of the present invention has the following beneficial effects:

[0016] The installation is performed without affecting the normal operation of the transmission line. When the disconnection is required, the control mechanism drives the joystick to rotate, so that the disconnector switches from closing to opening. When the second toggle assembly drives the second sensor to operate, the second sensor sends an opening signal, and the control mechanism stops working. At this time, the disconnector is in the opening state.

DETAILED DESCRIPTION

[0026] In order to facilitate the understanding of the present invention, the present invention will be described more fully below, and preferred embodiments of the present invention are provided. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the understanding of the disclosure of the present invention more thorough and comprehensive.

[0027] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used in the specification of the present invention herein are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0028] Example:

[0029] See also Figure 1-Figure 6 The present embodiment provides a one-button sequential control double confirmation device for an isolating switch, comprising a bracket 1, a first sensor 2, a first toggle assembly 3, a second sensor 4 and a second toggle assembly 5. The bracket 1 is fixedly connected to a housing 81 of an operating mechanism 8. The first sensor 2 and the second sensor 4 are both detachably connected to the bracket 1. The first sensor 2 and the second sensor 4 are distributed up and down. The first toggle assembly 3 and the second toggle assembly 5 are both detachably connected to a joystick 82 of the operating mechanism 8. The first toggle assembly 3 is arranged correspondingly to the first sensor 2 so that the first toggle assembly 3 triggers the first sensor 2 to work or stop when the joystick 82 of the operating mechanism 8 rotates. The second toggle assembly 5 and the second sensor 4 are arranged correspondingly so that the first toggle assembly 3 triggers the first sensor 2 to work or stop when the joystick 82 of the operating mechanism 8 rotates. The first toggle assembly 3 and the second toggle assembly 5 are arranged at an angle to each other.

[0030] It should be noted that the isolating switch one-button sequential control double confirmation device is used to be installed on the isolating switch as an auxiliary device of the isolating switch. Specifically, the bracket 1 is detachably connected to the housing 81 of the isolating switch operating mechanism 8 by bolts, and the first toggle assembly 3 and the second toggle assembly 5 are both detachably connected to the joystick 82 of the isolating switch operating mechanism 8. The isolating switch one-button sequential control double confirmation device is generally used in a one-button sequential control system, and is remotely controlled and monitored by an external circuit.

[0031] It can be understood that the first sensor 2 and the second sensor 4 are both installed on the bracket 1. Because it is necessary to ensure that the normal operation of the transmission line is not affected, when the device is installed, the disconnector is in the closed state. Therefore, when the first toggle assembly 3 is installed, the first contact block 33 in the first toggle assembly 3 is pressed on the first sensor 2, so that the first sensor 2 sends a closing signal; according to the design parameters of the disconnector opening, the angle required for the joystick 82 to rotate from the closed state to the open state is determined, and the second toggle assembly 5 is installed so that the second toggle assembly 5 and the first toggle assembly 3 form an angle, which is consistent with the angle required for the joystick 82 to rotate from the closed state to the open state. Through such an arrangement and installation method, when the opening is required, the control mechanism drives the joystick 82 to rotate, so that the disconnector changes from the closed state to the open state. When the second toggle assembly 5 drives the second sensor 4 to act, the second sensor 4 sends an opening signal, and the control mechanism stops working. At this time, the disconnector is in the open state. It can be known that if the control mechanism stops working in advance, the second sensor 4 will not be activated and no opening signal will be issued. The external circuit will make the control mechanism continue to work until the second sensor 4 is activated to prevent incomplete opening. Similarly, when closing the circuit, the first sensor 2 will not be activated to prevent loose closing.

[0032] As a preferred embodiment, the first toggle assembly 3 includes a first mounting block 31, a first locking block 32, a first contact block 33, a first fastener 34 and a second fastener 35. The first mounting block 31 and the first contact block 33 are fastened to the joystick 82 of the operating mechanism 8 by the first fastener 34. The first locking block 32 is provided with a first mounting hole 311, and the first contact block 33 is provided with a second mounting hole 331. The first contact block 33 is detachably connected to the first mounting block 31 by the second fastener 35, and the second fastener 35 is arranged to pass through the first mounting hole 311 and the second mounting hole 331 at the same time.

[0033] It can be understood that the first locking block 32 and the first mounting block 31 are fixedly connected to the joystick 82 by the first fastener 34, and the first touch block 33 is fixedly connected to the first mounting block 31 by the second fastener 35. Then the first fastener 34 is loosened, and the relative positions of the first mounting block 31, the first locking block 32 and the first touch block 33 relative to the first sensor 2 are adjusted so that the first touch block 33 is pressed on the first sensor 2. It can be known that the first touch block 33 rotates with the joystick 82, thereby driving the first sensor 2 to operate. It should be noted that in this embodiment, the first fastener 34 and the second fastener 35 are both bolts. In some other embodiments, the first fastener 34 and the second fastener 35 can also be screws, and other components or structures that can play a fastening role.

[0034] It should be noted that the second toggle assembly 5 is similar in structure to the first toggle assembly 3 and has similar functions, which will not be described in detail here.

[0035] As a preferred embodiment, at least one of the first mounting hole 311 and the second mounting hole 331 is an elongated hole, and the elongated holes are arranged along the length direction of the first mounting block 31. In this embodiment, the first mounting hole 311 and the second mounting hole 331 are both elongated holes as an example.

[0036] It can be known that when the first touch block 33 is far from the first sensor 2, the second fastener 35 can be loosened and the relative position of the first touch block 33 and the first mounting block 31 can be adjusted to move the first touch block 33 in the length direction of the first mounting hole 311, so that the first touch block 33 moves to a suitable position, that is, in the closed state, the first touch block 33 can be smoothly pressed to the first sensor 2, so that the first sensor 2 can receive a signal. The setting of the long strip hole can facilitate the adjustment of the position of the first touch block 33, without setting touch blocks of various length specifications.

[0037] As a preferred embodiment, the first shifting assembly 3 further includes a cushion block 36 , which is placed between the first mounting block 31 and the first contact block 33 to adjust the position of the first contact block 33 along the height direction.

[0038] It can be known that when the first toggle assembly 3 cannot contact the first sensor 2 in the height direction, on the one hand, the relative position of the first mounting block 31 on the joystick 82 can be adjusted. When the position of the first mounting block 31 cannot be adjusted due to some narrow space, the problem can be well solved by arranging a cushion block 36 between the first mounting block 31 and the first contact block 33. The thickness of the cushion block 36 is between 1 mm and 10 mm.

[0039] As a preferred embodiment, the first toggle assembly 3 further includes a locking screw 37 . A threaded hole is provided on the first locking block 32 . The locking screw 37 is threadedly connected to the threaded hole, and the locking screw 37 is pressed against the operating rod 82 of the operating mechanism 8 .

[0040] It can be known that during installation, the first fastener 34 is pre-tightened first, and the pre-tightened first mounting block 31 and the first locking block 32 are connected together through the first fastener 34, and at this time, the first mounting block 31, the second mounting block 51 and the first fastener 34 can rotate and move up and down around the joystick 82 together, and the first mounting block 31, the second mounting block 51 and the first fastener 34 are moved to the set position, and the tightening screw 37 is tightened. At this time, the first mounting block 31, the second mounting block 51 and the first fastener 34 are fixed on the joystick 82. It should be noted that the first mounting block 31 and the first locking block 32 can also be fastened and connected to the joystick 82 by tightening the first fastener 34, and it is more convenient to adjust by the tightening screw 37.

[0041] As a preferred embodiment, it also includes an angle control component 6, which includes a pointer 61 and a fourth fastener 62. The second toggle component 5 includes a second mounting block 51. The pointer 61 is fastened to the second mounting block 51 by the fourth fastener 62. The pointer 61 is arranged toward the first mounting block 31, and an angle scale line is set on the side of the first mounting block 31 close to the pointer 61.

[0042] It should be noted that the existing equipment needs to be installed without affecting the normal operation of the high-voltage line, that is, the installation of the first sensor 2 and the first toggle assembly 3 for detecting the closing signal and the installation of the second sensor 4 for detecting the opening signal need to be installed when the disconnector is in the closed state. Because the disconnector is always in the closed state during the installation process, when installing the first sensor 2 and the second toggle assembly 5, the first toggle assembly 3 drives the first sensor 2 to operate, so that the first sensor 2 is in the state of sending a closing signal; and when installing the second sensor 4 and the second toggle assembly 5, they can only be installed according to the rotation angle of the joystick 82 in the operating mechanism 8 when the switch is opened, that is, when the second toggle assembly 5 is turned, the joystick 82 in the operating mechanism 8 is turned. 5, the second toggle assembly 5 is installed at an angle offset from the first toggle assembly. When the joystick 82 is rotating in the opening process, when the second toggle assembly 5 triggers the second sensor 4 to send an opening signal, the joystick 82 stops rotating. If the angle between the first toggle assembly 3 and the second toggle assembly 5 is too small, the joystick 82 rotates at a small angle, which may lead to incomplete opening, thus causing danger. If the angle between the first toggle assembly 3 and the second toggle assembly 5 is too large, the joystick 82 rotates at a too large angle, which may also lead to incomplete opening. In addition, there is also the possibility that the angle is rotated excessively, causing collisions between some components on the disconnector and damaging the disconnector. Therefore, during the installation process, strictly controlling the angle between the second toggle assembly 5 and the first toggle assembly 3 is the key to ensuring that the disconnector can open normally when power is off. In this embodiment, the fourth fastener 62 is a screw. In some other embodiments, the fourth fastener 62 can also be a component or structure that can play a tightening role, such as a rivet or a bolt.

[0043] It can be understood that the first end of the pointer 61 is fixedly connected to the second mounting block 51 by the fourth fastener 62, and the second end of the pointer 61 is close to the first mounting block 31 and corresponds to the angle scale line on the first mounting block 31. When the second mounting block 51 rotates relative to the first mounting block 31, the angle scale line pointed to by the second end of the pointer 61 changes. By adjusting the angle, the value of the scale line pointed to by the second end of the pointer 61 can accurately determine the angle between the second toggle assembly 5 and the first toggle assembly 3, thereby further ensuring that when the isolating switch is in the opening operation, the joystick 82 can be smoothly rotated to the appropriate position and stopped, ensuring the correct opening of the isolating switch.

[0044] As a preferred embodiment, the pointer 61 includes a needle 611 and a needle seat 612, and the needle 611 is telescopically connected to the needle seat 612.

[0045] Specifically, an assembly hole is arranged on the needle seat 612 in the height direction, and the needle seat 612 is interference-fitted in the assembly hole. The interference fit generates friction force to prevent the needle 611 from moving relative to the needle without the action of external force.

[0046] It can be known that when the distance between the first sensor 2 and the second sensor 4 changes, the distance between the first toggle assembly 3 and the second toggle assembly 5 may also change. If the length of the pointer 61 cannot change, the first toggle assembly 3 and the second toggle assembly 5 cannot move in a direction close to each other, and if they move in a direction away from each other, the first toggle assembly 3 will be away from the needle 611, which will cause inaccurate readings when adjusting the first toggle assembly 3 or the second toggle assembly 5 because the pointer 61 is too far away from the angle scale line on the first toggle assembly 3, affecting the adjustment accuracy. The two shortcomings can be solved by a retractable manner, which facilitates the adjustment of the distance between the first toggle assembly 3 and the second toggle assembly 5, and makes the needle 611 of the pointer 61 close to the angle scale line on the first toggle assembly 3, which is conducive to improving the accuracy of the readings.

[0047] As a preferred embodiment, the first sensor 2 is a micro switch, the trigger arm of the micro switch is arranged toward the first toggle component 3, the second sensor 4 is also a micro switch, a through hole 11 is provided on the bracket 1, the trigger arm of the micro switch passes through the through hole 11 and is arranged toward the second toggle component 5.

[0048] It can be known that the micro switch is a mechanical toggle switch, which requires less toggle force and is sensitive and reliable in response. The first contact block 33 rotates with the joystick 82 in the operating mechanism 8, thereby driving the touch arm of the micro switch of the first sensor 2 to move, and the touch arm of the first sensor 2 moves and sends an in-place signal. Because the first sensor 2 on the isolating switch corresponds to the closed position of the isolating switch, the in-place signal sent by the touch arm of the first sensor 2 is a closing signal, that is, the isolating switch is in the closed state at this time. Similarly, when the joystick 82 in the operating mechanism 8 of the second toothing block rotates and drives the touch arm of the second sensor 4 to move, because the second sensor 4 on the isolating switch corresponds to the open position of the isolating switch, the touch arm of the second sensor 4 sends an in-place signal as an open signal, that is, the isolating switch is in the open state at this time.

[0049] As a preferred embodiment, it further comprises a first protective cover 7, which is arranged outside the first sensor 2, and is provided with a first through hole 71 and a second through hole 72, the trigger arm of the first sensor 2 is arranged through the first through hole 71, and the connecting line of the first sensor 2 is connected to the outside through the second through hole 72. It further comprises a second protective cover, which is arranged outside the second sensor 4, and is provided with a third through hole and a fourth through hole, the trigger arm of the second sensor 4 is arranged through the third through hole, and the connecting line of the second sensor 4 is connected to the outside through the fourth through hole.

[0050] It can be known that the first sensor 2 and the second sensor 4 are protected respectively by the first protective cover 7 and the second protective cover to prevent external rainwater from entering and causing damage to the first sensor 2 or the second sensor 4.

[0051] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
