Description

Technical Field

[0001] This invention relates to the field of power safety technology, and in particular to a disconnector status detection system, method, device and storage medium. Background Technology

[0002] In some power equipment applications, transmission mechanisms with low operating frequency (e.g., a few to a few hundred times per month) and installed in complex electromagnetic environments are required. The use of these transmission mechanisms necessitates long-term monitoring of their transmission status, for example, in the disconnector devices of unattended substations, to ensure the safety of the power equipment and maintenance personnel. The existing disconnect switch status monitoring system is as follows: A disconnect switch opening / closing status detection device includes: a base, fixed to the disconnect switch device, and having a first mounting hole through which the output shaft of the disconnect switch device can rotatably pass; a detection component, disposed on the base; a rotating component, rotatably mounted on the base, the rotating component having an open position indicating the disconnect switch body is separated and an closed position indicating the disconnect switch body is engaged, the rotating component also having a theoretical closed position and a theoretical open position; a sensing component, disposed on the edge of the rotating component, and rotating with the rotating component to correspond to or move away from the detection component, so that the detection component can detect the position of the sensing component; and an angle positioning component and a drive component, the drive component being used to intermittently connect the output shaft and the rotating component, the angle positioning component being able to automatically position the rotating component to the theoretical open position or theoretical closed position through the drive component, so as to compensate for the rotation angle difference of the output shaft; wherein, the drive component includes a transition component and an adjustment component that can be nested and intermittently connected, the transition component being mounted on the output shaft, the adjustment component being rotatably mounted in the first mounting hole, and the rotating component being mounted on one end of the adjustment component, the transition component and the adjustment component being intermittently driven to drive the rotating component to rotate.

[0003] Existing disconnector status monitoring systems involve installing detection components or devices on the disconnector body itself. Since disconnectors are primary equipment, installing detection components or devices on the disconnector body via a transmission mechanism (such as gears) to drive the detection components to rotate is not only structurally complex, but also requires direct connection to the primary equipment body. The operating voltage (3.3V-220V) of the detection device installed inside the primary equipment differs from the operating voltage (10KV-500KV) of the primary equipment body by several orders of magnitude. Once a leakage fault occurs, it will cause serious consequences, posing a significant safety hazard and resulting in low safety. Furthermore, existing detection methods require continuous power supply to achieve real-time monitoring, leading to high power consumption for real-time disconnector status monitoring.

Detailed Implementation

[0022] This invention provides a disconnector status detection system, method, device, and storage medium, which effectively reduces the power consumption of real-time disconnector status monitoring.

[0023] The terms "first," "second," "third," "fourth," etc. (if present) in the specification, claims, and accompanying drawings of this invention are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments described herein can be implemented in orders other than those illustrated or described herein. Furthermore, the terms "comprising" or "having" and any variations thereof are intended to cover a non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.

[0024] For easier understanding, please refer to Figure 1 , Figure 1This is a schematic diagram of a disconnect switch status detection system provided in an embodiment of the present invention. The disconnect switch status detection system includes at least two sensing circuits for detecting the rotational position of the disconnect switch. A triggering device is installed on the rotation mechanism of the disconnect switch to trigger the sensing circuits, thereby activating the corresponding detection circuits. As an example, and not a limitation, the triggering device can be a magnetic induction device, such as a magnet, or an infrared sensing device, such as an infrared photodiode. The triggering device is not limited to magnets or infrared photodiodes. As an example, and not a limitation, during installation, the disconnect switch status detection system is fixed to a support (e.g., a support column) by clamps. This support is located at a certain distance from the rotation mechanism of the disconnect switch and is parallel to the rotation mechanism. The positions of the at least two sensing circuits correspond to the positions of the triggering device (e.g., a magnet). It can be understood that the triggering device and the at least two sensing circuits are on the same horizontal plane, and the at least two sensing circuits are distributed and surround the triggering device. Figure 2 As shown; The status display device includes a control unit and a display unit. The control unit controls the power supply device to stop supplying power, and the display unit displays the status information corresponding to the disconnect switch. The power supply device provides power to the sensing circuit and the status display device. The status display device, the power supply device and each sensing circuit are connected in series to form at least two detection loops. Each detection loop corresponds to a state of the disconnector. The at least two detection loops include an open detection loop and an closed detection loop. When the switch rotates to the corresponding target position, the target detection circuit in at least two detection circuits is turned on, the control unit works, the control display unit displays the status information corresponding to the target detection circuit, and the power supply device stops supplying power to the target detection circuit.

[0025] Disconnectors are primary equipment. If detection components or devices are installed on the disconnector body, they must be directly connected to the primary equipment body. However, the operating voltage (3.3V-220V) of the detection device installed inside the primary equipment differs from the operating voltage (10KV-500KV) of the primary equipment body by several orders of magnitude. Once a leakage fault occurs, it will cause serious consequences, namely, a significant safety hazard. Furthermore, existing disconnector status detection devices require an external power supply. If a leakage occurs, it may connect the 220V to the high-voltage bus, causing the high-voltage bus to trip and resulting in serious damage. However, the disconnector status detection system provided by this invention does not require an external power supply and is not directly connected to systems of other voltage levels. Therefore, the disconnector status detection system does not have the above-mentioned problems.

[0026] It should be noted that the initial position corresponding to the sensing circuit is the position of the knife switch being closed and open. Compared with the common fisheye indicator installed in the knife switch of a Geographic Information System (GIS), which needs to be directly installed on the rotating mechanism of the knife switch through transmission mechanisms and other components, the installation position is fixed and the display angle cannot be adjusted due to the complex transmission mechanism, the knife switch status detection system of the present invention eliminates the need to install the sensor (sensing component) in the sensing circuit on the knife switch, greatly reducing the complexity of the transmission and improving reliability.

[0027] Optionally, the power supply device may be a battery or other low-power power supply device, such as a lithium battery or a dry cell battery, without limitation, and low power consumption is achieved by power supply devices such as batteries.

[0028] Optionally, the status display device can achieve simultaneous control of the control unit and the display unit, i.e., parallel operation of the control unit and the display unit, or sequential control of the control unit and the display unit, i.e., operation of the control unit and the display unit according to a certain timing logic. Specific details are not limited here. It can be implemented based on the actual connection relationships between the various devices and units.

[0029] Optionally, the number of sensing circuits corresponds to the number of detection loops, that is, one sensing circuit corresponds to one detection loop.

[0030] Optionally, each sensing circuit includes at least one sensing component; the sensing circuits are connected in parallel, the sensing components in each sensing circuit are connected in series, and are connected in series with the power supply device and the status display device to form at least two detection loops. The sensing components in each sensing circuit are set according to the actual circuit function and are not limited here.

[0031] Optionally, the sensing component may be a metal proximity probe, photoelectric sensor, Hall effect sensor, limit switch or reed switch or other device, not limited to the aforementioned metal proximity probe, photoelectric sensor, Hall effect sensor, limit switch or reed switch, and is not limited herein.

[0032] Optionally, the sensing component in each sensing circuit is a magnetic sensor, used to magnetically sense the rotational position of the knife switch in order to activate the corresponding detection circuit.

[0033] Optionally, at least two sensing circuits also include an abnormal position detection circuit. The sensing components in the at least two sensing circuits include an open position sensing component and an closed position sensing component. Both the open position sensing component and the closed position sensing component include normally open output terminals and normally closed output terminals. The installation position of the open position sensing component corresponds to the open position of the disconnector, and the installation position of the closed position sensing component corresponds to the closed position of the disconnector. That is, three detection circuits can be formed by two sensing components, a power supply device, and a status display device.

[0034] The normally open output terminal of the position sensing component is connected in series with the power supply device and the status display device to form a position detection circuit. The normally open output terminal of the position sensing component is connected in series with the power supply device and the status display device to form a position detection circuit. The normally closed output terminal of the position separation sensing component and the normally closed output terminal of the position closing sensing component are connected in series, and are also connected in series with the power supply device and the status display device to form an abnormal position detection circuit.

[0035] When the disconnector is in the open position, the open position sensing component is triggered, while the closed position sensing component is not triggered. The open position detection circuit is on, while the closed position detection circuit and the abnormal position detection circuit are off. The triggering of the open position sensing component and the non-triggering of the closed position sensing component can be understood as: the normally open output terminal of the open position sensing component is closed, the normally closed output terminal of the open position sensing component is open, the normally open output terminal of the closed position sensing component is open, and the normally closed output terminal of the open position sensing component is closed.

[0036] When the disconnector is in the closed position, the closing position sensing component is triggered, while the opening position sensing component is not triggered. The closing position detection circuit is on, while the opening position detection circuit and the abnormal position detection circuit are off. The closing position sensing component being triggered while the opening position sensing component is not triggered can be understood as follows: the normally open output terminal of the closing position sensing component is closed, the normally closed output terminal of the closing position sensing component is open, the normally open output terminal of the opening position sensing component is open, and the normally closed output terminal of the opening position sensing component is closed.

[0037] When the disconnector rotates to an abnormal position, the normally closed sensing component in the open position sensing assembly and the normally closed sensing component in the closed position sensing assembly are connected, while the normally open sensing component in the open position sensing assembly and the normally open sensing component in the closed position sensing assembly are disconnected. The abnormal position detection circuit is connected, while the open position detection circuit and the closed position detection circuit are disconnected.

[0038] Optionally, at least two sensing circuits further include an abnormal position detection circuit, and the sensing components in the at least two sensing circuits include a normally open sensing component for open position, a normally open sensing component for closed position, a normally closed sensing component for open position, and a normally closed sensing component for closed position. The installation positions of the normally open sensing component for open position and the normally closed sensing component for open position correspond to the open position of the disconnector, and the installation positions of the normally open sensing component for closed position and the normally closed sensing component for closed position correspond to the closed position of the disconnector. The normally open position sensor is connected in series with the power supply device and the status display device to form a position detection circuit; The normally open closed position sensor is connected in series with the power supply device and the status display device to form a closed position detection circuit; The normally closed sensing component for the open position and the normally closed sensing component for the closed position are connected in series, and are also connected in series with the power supply device and the status display device to form an abnormal position detection circuit.

[0039] When the disconnector is in the open position, the normally open open sensing component is on, the normally closed open sensing component is off, the open position detection circuit is on, and the closed position detection circuit and the abnormal position detection circuit are off. When the disconnector is in the closed position, the normally open closed closing sensing component is on, the closed position detection circuit is on, and the open position detection circuit and the abnormal position detection circuit are off. When the disconnector is rotated to the abnormal position, the normally open open open sensing component and the normally open closed closing sensing component are not on, the abnormal position detection circuit is on, and the open position detection circuit and the closed position detection circuit are off.

[0040] Furthermore, the aforementioned magnetic sensor is a reed switch. Optionally, the aforementioned normally open separation sensing component is a normally open separation reed switch, the aforementioned normally open closing sensing component is a normally open closing closing reed switch, the aforementioned normally closed separation sensing component is a normally closed separation reed switch, and the aforementioned normally closed closing closing sensing component is a normally closed closing closing reed switch.

[0041] Optionally, the control unit includes a drive mechanism and at least two first on / off components, wherein the display unit is connected to the drive mechanism; The drive mechanism is used to control the display unit to display the status information of the switch, and to disconnect the corresponding detection circuit through the corresponding first switching component; The first on / off component is used to connect or disconnect the detection circuit.

[0042] An induction circuit is connected in series with a first switching component to form a switching branch; Each on / off branch is connected in parallel to each other and in series with the display unit, power supply device and drive mechanism to form at least two detection loops.

[0043] The following explains why the control unit needs to be involved in stopping the power supply. When the display unit is mechanical, such as a turntable, stopping the power supply is achieved when the control unit's drive mechanism drives the turntable to the corresponding position. The turntable triggers one of the on / off components, the detection circuit is disconnected, and the power supply device stops supplying power to the drive mechanism. Therefore, the process of stopping the power supply also requires the involvement of the drive mechanism.

[0044] When the switch rotates to the corresponding target position, the corresponding on / off branch is turned on, the target detection circuit corresponding to the on / off branch is turned on, the drive mechanism works, the control display unit displays the status information corresponding to the target detection circuit, and disconnects the target detection circuit through the corresponding first on / off component, and the power supply device stops supplying power to the target detection circuit.

[0045] Optionally, in this embodiment of the invention, the preferred first switching component is a micro switch with small contact spacing, short actuation stroke, low actuation force, and rapid switching. Further, the aforementioned first switching component can be a normally closed micro switch.

[0046] Furthermore, the first on / off component corresponding to the vacancy detection circuit is a normally closed micro switch for vacancy, the first on / off component corresponding to the close detection circuit is a normally closed micro switch for close, and the first on / off component corresponding to the abnormal position detection circuit is a normally closed micro switch for abnormal position. At least two on / off branches corresponding to at least two first on / off components include a vacancy on / off branch, a close on / off branch, and an abnormal position on / off branch.

[0047] Furthermore, the sensing components in at least two sensing circuits include an open-position sensing component and an closed-position sensing component. Both the open-position and closed-position sensing components include normally open and normally closed output terminals. The installation position of the open-position sensing component corresponds to the open position of the disconnector, and the installation position of the closed-position sensing component corresponds to the closed position of the disconnector. The corresponding detection circuits are as follows: Figure 3 As shown, SR1 is the position sensing component, SR1-1 is the normally open output terminal of the position sensing component, SR1-2 is the normally closed output terminal of the position sensing component, SR2 is the position sensing component, SR2-1 is the normally open output terminal of the position sensing component, SR2-2 is the normally closed output terminal of the position sensing component, SW1 is the normally closed micro switch for position, SW2 is the normally closed micro switch for position, SW3 is the normally closed micro switch for abnormal position, BT1 is the battery (i.e., the power supply device), and M1 is the status display device (taking the motor in the status display device as part of the circuit display as an example for explanation). SR1-1, SW1, BT1, and M1 are connected in series to form the position detection circuit, SR2-1, SW2, BT1, and M1 are connected in series to form the position detection circuit, and SR1-2, SR2-2, SW3, BT1, and M1 are connected in series to form the abnormal position detection circuit. The position detection circuit, the position detection circuit, and the abnormal position detection circuit are connected in parallel with each other.

[0048] Furthermore, the sensing components in at least two sensing circuits include a normally open sensing component for the open position, a normally open sensing component for the closed position, a normally closed sensing component for the open position, and a normally closed sensing component for the closed position. The installation positions of the normally open and normally closed sensing components for the open position correspond to the open position of the disconnector, and the installation positions of the normally open and normally closed sensing components for the closed position correspond to the closed position of the disconnector. The corresponding detection circuits are as follows: Figure 4As shown, SR3 is a normally open reed switch for the open position, SR4 is a normally open reed switch for the closed position, SR5 is a normally closed reed switch for the open position, SR6 is a normally closed reed switch for the closed position, BT1 is a battery (i.e., a power supply device), M1 is a status display device (taking the motor in the status display device as part of the circuit display as an example for explanation), SW1 is a normally closed micro switch for the open position, SW2 is a normally closed micro switch for the closed position, and SW3 is a normally closed micro switch for the abnormal position. SR3 and SW1 are connected in series to form the open position on / off branch, SR4 and SW2 are connected in series to form the closed position on / off branch, SR5, SR6 and SW3 are connected in series to form the abnormal position on / off branch, SR3, SW1, BT1 and M1 are connected in series to form the open position detection circuit, SR4, SW2, BT1 and M1 are connected in series to form the closed position detection circuit, and SR5, SR6, SW3, BT1 and M1 are connected in series to form the abnormal position detection circuit. The open position detection circuit, the closed position detection circuit and the abnormal position detection circuit are connected in parallel with each other.

[0049] Optionally, the drive mechanism is an electric motor, and the display panel is connected to the drive shaft of the electric motor; The aforementioned display panel is used to display the status information corresponding to the knife switch; the aforementioned motor is used to control the movement or stop movement of the display panel.

[0050] When the target detection circuit is activated, the motor rotates, which in turn drives the display panel to rotate via the transmission shaft.

[0051] Optionally, the display unit includes a display disk and a first trigger unit disposed on the display disk. Multiple display areas are provided on the front of the display disk, and each display area corresponds to a status information. The aforementioned first trigger unit is used to disconnect the first on / off component.

[0052] When the target detection circuit is turned on, the drive mechanism drives the display disk to rotate and disconnects the corresponding second on / off component through the first trigger part.

[0053] like Figure 5 As shown, when the target detection circuit is turned on, the drive mechanism drives the display disk to rotate, and the first trigger part on the display disk presses the micro switch (i.e. the first on / off component) to disconnect the first on / off component.

[0054] Optionally, the first trigger unit is located on the back of the display panel.

[0055] Optionally, each display area has the same area, and each display area includes status information, which can be text, color, or other formats. The status information corresponding to multiple display areas can be arranged in a preset order, such as... Figure 6 As shown.

[0056] Optionally, the display panel includes a turntable and a fixed panel. The fixed panel is provided with an observation window, and the front of the turntable is provided with multiple display areas. The first trigger part is located on the back of the turntable. The turntable is connected to the drive shaft of the motor. When the target detection circuit is activated, the motor rotates and drives the turntable to rotate via the transmission shaft. When the turntable stops rotating, the status information corresponding to the display area when the turntable stops is displayed through the observation window.

[0057] Optionally, the disconnector status detection system also includes an image acquisition unit. As an example, and not a limitation, the image acquisition unit can be a camera; this is not specific. The image acquisition unit is used to acquire the status information displayed on the display panel. This method can be combined with video recognition technology. Because the disconnector's movements are relatively small and located inside the structure, making them somewhat concealed, and because directly acquiring the disconnector's movements using an image acquisition unit (camera) for video recognition is challenging, this method is adopted to ensure accuracy and address the issue that a single camera can only acquire the movements of one disconnector. The disconnector's status information is displayed on the display panel, and the camera (image acquisition unit) captures the status information displayed on the panel. Video analysis of the captured information enables video recognition of the disconnector's movement status, and allows one image acquisition unit (camera) to simultaneously acquire the status of multiple disconnectors within a given area.

[0058] The first trigger section is as follows Figure 7 As shown.

[0059] Optionally, the display panel may also be equipped with a second trigger unit; The aforementioned second triggering unit is used to trigger the second on / off component to turn on the wireless communication circuit; When the drive mechanism drives the display disk to rotate to the position corresponding to the status information, the second trigger unit triggers the corresponding second on / off component, and the wireless communication branch is turned on.

[0060] Optionally, the first trigger is located on one side of the display panel, and the second trigger is located on the other side of the display panel.

[0061] Optionally, the above-mentioned display unit is an electronic display assembly; the driving mechanism is a controller; The aforementioned electronic display component is used to display the status information corresponding to the disconnect switch; Each on / off branch is connected in parallel to each other and in series with the controller and power supply to form at least two detection loops. The electronic display component is connected in parallel with the power supply, such as... Figure 8 As shown. By way of example and not limitation, the controller may be a single-chip microcomputer or microcontroller; the electronic display component may be a liquid crystal display screen; and the first on / off component may be a control switch.

[0062] When the target detection circuit is on, the controller (drive component) sends the status information corresponding to the target detection circuit to the display unit through a display command. After receiving the display command, the display unit displays the corresponding status information. When the controller (drive component) sends the status information corresponding to the target detection circuit to the display unit through a display command, it sends a disconnect command to the first on / off component to disconnect the first on / off component, thereby disconnecting the target detection circuit. The power supply device stops supplying power to the target detection circuit.

[0063] Optionally, the above-mentioned display unit can be a mechanical display assembly, and the driving mechanism is a controller. A sensing circuit is connected in series with a first on / off component to form an on / off branch; The aforementioned mechanical display component is used to display the status information corresponding to the disconnect switch; Each on / off branch is connected in parallel to each other and in series with the display unit, power supply device and drive mechanism to form at least two detection loops.

[0064] Optionally, the aforementioned mechanical display component is an indicator with a blocking component, one indicator corresponding to one state of the knife switch; the blocking component is used to block or display the state information of the indicator; the drive mechanism is also used to control the extension and retraction of the blocking component, as well as the connection and disconnection of the first on / off component.

[0065] In this embodiment of the invention, the disconnect switch status detection system can detect the status of the disconnect switch without installing complex components such as transmission mechanisms on the primary equipment such as the disconnect switch. That is, no modification to the primary equipment is required, so the installation is very convenient. Moreover, by maintaining a certain distance from the operating voltage of the disconnect switch, the safety hazards caused by leakage faults can be avoided, thus improving safety performance. Through the disconnect switch status detection system, continuous power supply without external wiring is achieved, its status detection is not affected by the power supply of the transmission mechanism, and the power supply device is only consumed when the status is being detected, thereby effectively reducing the power consumption of real-time monitoring of disconnect switch status.

[0066] In another feasible embodiment, based on the above-mentioned disconnector status detection system, the disconnector status detection system further includes a wireless communication circuit, which is connected in series with each detection loop; when the control unit controls the wireless communication circuit to be turned on, the wireless communication circuit sends the corresponding status information to the transceiver device.

[0067] It should be noted that since the operating voltage of the disconnect switch is relatively high, usually 380VAC, installing a wireless communication module on the primary equipment body of the disconnect switch poses a significant reliability problem. Furthermore, the high voltage of the disconnect switch will generate electromagnetic interference. This application does not require installation on the disconnect switch body, thus maintaining a certain distance from the high voltage and having a strong anti-electromagnetic interference capability.

[0068] Optionally, the wireless communication circuit includes at least two second switching components and a wireless communication branch, with one second switching component corresponding to one detection loop; each second switching component is connected in parallel with each other and in series with the wireless communication branch; When the drive mechanism drives the display disk to rotate to the position corresponding to the status information, the corresponding second on / off component is triggered, the wireless communication branch is turned on, and the wireless communication branch sends the corresponding status information to the transceiver device based on wireless communication.

[0069] Optionally, the second switching component is a micro switch with small contact spacing, short operating stroke, low actuation force, and rapid switching. The second switching component can be a normally open micro switch.

[0070] Optionally, the wireless communication branch includes a wireless transceiver circuit and an antenna; the wireless transceiver circuit and the antenna are connected in series, and a second switching component, the wireless transceiver circuit, and the antenna connected in series form a circuit loop; the wireless transceiver circuit includes a controller for the wireless circuit. Optionally, the controller for the wireless circuit can be a microcontroller or a single-chip microcomputer. The positions of each second switching component correspond to the positions of each state.

[0071] As an example, and not a limitation, the detection loop and wireless communication circuit, such as Figure 9 As shown, Figure 9 Taking two first on / off components and two second on / off components as an example. When the target detection circuit is on, the motor drives the turntable to rotate via the rotating shaft. When the turntable rotates to the position corresponding to the target detection circuit, the corresponding first trigger unit presses the first on / off component in the target detection circuit, the target detection circuit is disconnected, and the power supply device stops supplying power to the target detection circuit. The corresponding second trigger unit presses the second on / off component in the target detection circuit, the wireless communication branch is on, the controller obtains the corresponding status information, and sends the corresponding status information to the transceiver device wirelessly via the antenna.

[0072] In this embodiment of the invention, the disconnect switch status detection system can detect the status of the disconnect switch without installing complex components such as transmission mechanisms on the primary equipment such as the disconnect switch. This means no modification to the primary equipment is required, making installation very convenient. Furthermore, maintaining a certain distance from the operating voltage of the disconnect switch avoids safety hazards caused by leakage faults and improves safety performance. In addition, it avoids electromagnetic interference caused by the operating voltage of the disconnect switch, thus having wide applicability. Through wireless communication circuitry, it enables wireless monitoring of the status of the disconnect switch and other mechanisms in complex electromagnetic environments, giving the disconnect switch status detection system strong anti-electromagnetic interference capabilities.

[0073] For ease of understanding, the specific process of the embodiments of the present invention is described below. Please refer to [link / reference]. Figure 10 , Figure 10This is a schematic diagram of a disconnector status detection method provided in an embodiment of the present invention. The disconnector status detection method in this embodiment is applied to the aforementioned disconnector status detection system; that is, the description is based on the aforementioned disconnector status detection system as the executing entity. One embodiment of the disconnector status detection method in this invention includes: 101. The rotation position of the knife switch is detected by each sensing circuit, and the target detection circuit in at least two detection circuits is activated based on the rotation position.

[0074] The rotational position of the switch is detected by various sensing circuits, triggering the corresponding detection circuit (i.e., the target detection circuit) to conduct. After the target detection circuit is activated, the electrical signal corresponding to the rotational position is fed back to the status display device, which then processes the signal.

[0075] The disconnect switch has two positions: "open" and "closed". The open position corresponds to the disconnection of the high-voltage busbar, and the closed position corresponds to the conduction of the high-voltage busbar. The open position corresponds to the open position of the disconnect switch, and the closed position corresponds to the closed position of the disconnect switch. As an example, and not a limitation, if there are two detection circuits, these two circuits are respectively the detection circuit for detecting the open position (open position detection circuit) and the circuit for detecting the closed position (closed position detection circuit). If there are three detection circuits, these two circuits are respectively the detection circuit for detecting the open position (open position detection circuit), the circuit for detecting the closed position (closed position detection circuit), and the detection circuit for detecting abnormal positions (abnormal position detection circuit). The specific number of detection circuits is not limited here and is set according to the actual detection requirements. The abnormal position is used to indicate positions other than the open and closed positions, corresponding to positions other than the open and closed positions of the disconnect switch.

[0076] When the disconnect switch is driven to the open position (i.e., the open position), the sensing circuit corresponding to the open position is triggered, and the open position detection circuit (i.e., the target detection circuit) is activated. The corresponding detected state is that the disconnect switch is in the open position (or the disconnect switch is in the open position). When the disconnect switch is driven to the closed position, the sensing circuit corresponding to the closed position is triggered, and the closed position detection circuit (i.e., the target detection circuit) is activated. The corresponding detected state is that the disconnect switch is in the closed position (i.e., the closed position or the disconnect switch is in the closed position). When the disconnect switch is driven to any position other than the open and closed positions (i.e., the disconnect switch is in an abnormal position), the sensing circuit corresponding to the abnormal position is triggered, and the abnormal position detection circuit (i.e., the target detection circuit) is activated. The corresponding detected state is that the disconnect switch is in an abnormal position.

[0077] Here, by way of example and not limitation, the methods by which the sensing circuit is triggered include, but are not limited to, point-contact and inductive triggering methods. Point-contact method can be understood as follows: when the disconnect switch is driven to the corresponding position, the magnet on the disconnect switch touches the point at that position to trigger the corresponding sensing circuit. Inductive triggering method can be understood as follows: when the disconnect switch is driven to the corresponding position (i.e., open position, closed position, or abnormal position), the magnet on the disconnect switch operates the corresponding electrical switch at that position through the applied magnetic field, thereby triggering the corresponding sensing circuit.

[0078] In one feasible implementation, step 101 specifically includes: detecting whether the sensing components in each sensing circuit are triggered by the magnet on the rotating mechanism after the knife switch is rotated, and conducting the corresponding target detection circuit in at least two detection circuits according to the triggering result. The at least two detection circuits include a separation detection circuit, a closing detection circuit, and an abnormal position detection circuit.

[0079] The rotating mechanism of the knife switch is equipped with a magnet. In the prior art, the magnetic sensor (sensing element) is installed on the knife switch body through a transmission mechanism, such as an output shaft, a drive assembly, and a rotating component. The knife switch body electrically outputs a shaft, which drives the drive assembly to rotate, thereby causing the sensing element on the rotating component to rotate. The sensing element is installed on the stationary part of the knife switch. However, the sensing element of this invention does not need to be installed on the rotating mechanism of the knife switch. It can be installed on the knife switch bracket, or a separate bracket can be used for installation. There are no restrictions on this.

[0080] When the rotating mechanism of the disconnect switch rotates to the correct position (closed or open, i.e., the closed position or the disconnect switch position), the magnet on the rotating mechanism triggers the sensing component in the corresponding induction circuit, and the target (i.e., the target detection circuit) of the corresponding closed or open detection circuit is activated. When the rotating mechanism of the disconnect switch does not rotate to the correct position (i.e., an abnormal position, a position other than the closed or disconnect switch position) or a malfunction occurs, the sensing components in the closed or open detection circuits are not triggered, but the sensing component in the abnormal position detection circuit is triggered, and the corresponding abnormal position detection circuit (i.e., the target detection circuit) is activated. By detecting the state of the sensing components in each induction circuit, the state of the disconnect switch is determined, reducing the complexity of the transmission and improving the reliability of the disconnect switch state detection.

[0081] 102. When the control unit is in operation, the control display unit displays the corresponding status information and controls the power supply device to stop supplying power to the target detection circuit.

[0082] After the target detection loop is activated, the status display device operates, meaning the control unit controls the operation of the display unit and the power supply device. As an example, and not a limitation, the status display device can simultaneously control the control unit and the display unit, meaning they operate in parallel. This can be understood as the status display device controlling the display unit to display the corresponding status information while simultaneously controlling the power supply device to stop supplying power to the target detection loop. Alternatively, it can control the control unit and display unit sequentially, meaning they operate according to a specific timing logic. This can be understood as the status display device first controlling the display unit to display the corresponding status information via the control unit, and then controlling the power supply device to stop supplying power to the target detection loop, or vice versa. The specific implementation is not limited here. It can be achieved based on the actual connection relationships between the various devices and units.

[0083] In one feasible implementation, step 102 specifically includes: the drive mechanism operates to control the electronic display component to display corresponding status information; when the drive mechanism detects that the electronic display component displays status information, the drive mechanism controls the first on / off component in the target detection circuit to disconnect, so as to stop the power supply device from supplying power to the target detection circuit.

[0084] As an example, and not a limitation, after the target detection circuit is turned on, the drive mechanism (e.g., a circuit board that controls the display unit and triggers at least two first on / off components) operates and generates a corresponding display command based on the signal of the state corresponding to the corresponding sensing circuit (i.e., the rotation position of the knife switch), and sends the display command to the liquid crystal display screen (i.e., the electronic display component). When the liquid crystal display screen receives the display command, it feeds back the received information to the drive mechanism and displays the corresponding state information based on the display command. When the drive mechanism receives the information fed back by the liquid crystal display screen (i.e., the electronic display component), it sends a disconnect command to the control switch (i.e., the first on / off component). When the control switch receives the disconnect command, the control switch disconnects to disconnect the target detection circuit. The sensing component is in an untriggered state, and the power supply device stops supplying power, i.e., stops supplying power to the target detection circuit. Since the liquid crystal display screen (i.e., the electronic display component) is connected in parallel with the power supply device, the power supply device continues to supply power to the liquid crystal display screen (i.e., the electronic display component). That is, when the power supply device stops supplying power to the target detection circuit, the liquid crystal display screen (i.e., the electronic display component) still operates and displays the corresponding state information. By controlling the power supply device to stop supplying power to the target detection circuit, the detection circuit only consumes the power of the power supply device when it is in the detection state. After the state detection is completed, the detection circuit is disconnected and no longer consumes the power of the power supply device, which effectively reduces the power consumption of real-time monitoring of the switch status.

[0085] In one feasible implementation, the display unit is an indicator sign with a blocking component. Step 102 specifically includes: operating the drive mechanism to control the indicator sign to display corresponding status information, and triggering the first on / off component in the target detection circuit to disconnect the target detection circuit, thereby stopping the power supply device from supplying power to the target detection circuit. The first on / off component is a control switch.

[0086] The indicator signs equipped with blocking components are respectively a position indicator, a closed position indicator, and an abnormal position indicator. When the target detection circuit is activated, the drive mechanism (e.g., a circuit board with a control display unit and the function of triggering at least two first on / off components) operates, sending an operation command corresponding to the state to the indicator sign with the blocking component. When the indicator sign with the blocking component receives the operation command, it controls the blocking component of the indicator sign corresponding to the state to move in a set direction to display the state information on the indicator sign. This state information may include text indicating the state and a corresponding color. For example, if the target detection circuit is a position detection circuit, when the position detection circuit is activated, the drive mechanism operates, sending an operation command corresponding to the position state to the position indicator sign. When the position indicator sign receives the operation command, it controls the blocking component of the position indicator sign to move in a first set direction to display the state information on the indicator sign corresponding to the position state. This state information may include text indicating the position state and a corresponding color.

[0087] When the blocking component of the indicator corresponding to the detected state moves into place in the first set direction, the drive mechanism sends a disconnect command to the control switch (first on / off component). When the control switch receives the disconnect command, the control switch disconnects to disconnect the target detection circuit. The sensing component is in an untriggered state, and the power supply device stops supplying power, that is, stops supplying power to the target detection circuit.

[0088] It should be noted that when the detection circuit corresponding to the next state is triggered and turned on, the blocking component of the indicator corresponding to the previous state moves in the second set direction to block the state information on the indicator corresponding to the previous state.

[0089] In one feasible implementation, when the drive mechanism receives information from the LCD screen (i.e., the electronic display component), it sends the corresponding status information to the background (e.g., the server) to achieve remote monitoring of the switch status.

[0090] In this embodiment of the invention, the disconnect switch status detection system can detect the status of the disconnect switch without installing complex components such as transmission mechanisms on the primary equipment such as the disconnect switch. That is, no modification to the primary equipment is required, so the installation is very convenient. Moreover, by maintaining a certain distance from the operating voltage of the disconnect switch, the safety hazards caused by leakage faults can be avoided, thus improving safety performance. Through the structure of the disconnect switch status detection system itself and the power supply device therein, it achieves continuous power supply without external wiring. Its status detection is not affected by the power supply of the transmission mechanism, and the power of the power supply device is only consumed when the status is being detected. This effectively reduces the power consumption of real-time monitoring of the disconnect switch status.

[0091] Please see Figure 11 , Figure 11 This is a schematic diagram of another disconnector status detection method provided in an embodiment of the present invention, applied to the aforementioned disconnector status detection system. Another embodiment of the disconnector status detection method in this invention includes: 1101. When the normally open induction component is triggered by the rotating mechanism after the knife switch is rotated, the open detection circuit is turned on, and the closed detection circuit and the abnormal position detection circuit are turned off.

[0092] When the disconnect switch is rotated to the open position (i.e., the open position), the magnet (i.e., the triggering device) on the rotating mechanism of the disconnect switch magnetically triggers the normally open reed switch (i.e., the normally open sensing component) and the normally closed reed switch (i.e., the normally closed sensing component) in the open position. The normally open reed switch is connected, and the normally closed reed switch is disconnected. Neither the normally open nor the normally closed reed switch is triggered. The normally open reed switch is disconnected, and the normally closed reed switch is connected. The normally closed micro switch, the normally closed micro switch, and the normally closed micro switch for the abnormal position are not triggered. That is, the open position detection circuit (i.e., the target detection circuit) is on, and the closed and abnormal position detection circuits are off.

[0093] 1102. When the normally open closed sensing component is triggered by the triggering device on the rotating mechanism after the knife switch is rotated, the closed detection circuit is turned on, and the open detection circuit and the abnormal position detection circuit are turned off.

[0094] When the disconnect switch is rotated to the closed position (i.e., the closed position), the magnet (i.e., the triggering device) on the rotating mechanism of the disconnect switch magnetically triggers the normally open reed switch (i.e., the normally open sensing component) and the normally closed reed switch (i.e., the normally closed sensing component) in the closed position. The normally open reed switch is connected, and the normally closed reed switch is disconnected. Neither the normally open nor the normally closed reed switch is triggered. The normally open reed switch is disconnected, and the normally closed reed switch is connected. The normally closed micro switch, the normally closed micro switch, and the normally closed micro switch for the abnormal position are not triggered. That is, the closed detection circuit (i.e., the target detection circuit) is on, and the open and abnormal position detection circuits are off.

[0095] 1103. When the normally closed sensing component for the open position and the normally closed sensing component for the closed position are not triggered by the triggering device on the rotating mechanism after the switch is rotated, the open position detection circuit and the closed position detection circuit are disconnected, and the abnormal position detection circuit is turned on.

[0096] When the disconnect switch rotates to the position between open and closed (i.e., the abnormal position), the normally closed reed switch for open (i.e., the normally closed sensing component for open) and the normally closed reed switch for closed (i.e., the normally closed sensing component for open) are not triggered by the magnet (i.e., the triggering device) on the rotating mechanism of the disconnect switch. The normally closed reed switch for open and closed are connected, while the normally open reed switch for open and closed are disconnected. The normally closed micro switch for open, closed, and abnormal position are not triggered. That is, the abnormal position detection circuit (i.e., the target detection circuit) is on, while the open and closed detection circuits are off.

[0097] By triggering the corresponding sensing component with the magnet on the rotating mechanism after the switch rotates, the complexity of switch transmission and switch status detection is greatly reduced, and the reliability and convenience of switch status detection are improved.

[0098] 1104. The drive mechanism operates, the control display panel displays the corresponding status information, and triggers the first on / off component in the target detection circuit to disconnect, thereby stopping the power supply device from supplying power to the target detection circuit.

[0099] In one feasible implementation, step 1104 specifically includes: the motor working to drive the turntable to rotate; when the turntable rotates to the position corresponding to the first on / off component in the target detection circuit, the first trigger part on the turntable presses the first on / off component in the target detection circuit to stop the power supply device from supplying power to the target detection circuit; the motor stops working, the turntable stops rotating, and the corresponding status information is displayed.

[0100] For example, such as Figure 4 The detection circuit shown, taking the target detection circuit as an example of a sectionalizing detection circuit, is activated when the sectionalizing detection circuit is on, and the motor operates. The motor drives the turntable to rotate. When the turntable rotates to the position corresponding to the normally closed sectionalizing microswitch (i.e., the first on / off component) in the target detection circuit, the first trigger part presses the normally closed sectionalizing microswitch in the target detection circuit to trigger it, thereby opening the normally closed sectionalizing microswitch. When the normally closed sectionalizing microswitch is open, the corresponding sectionalizing detection circuit is disconnected, and the battery (i.e., power supply device) in the sectionalizing detection circuit stops working, i.e., power supply to the sectionalizing detection circuit stops. At the same time, the turntable in the sectionalizing detection circuit stops rotating and displays the corresponding status information. By using the status display of the motor (i.e., the drive mechanism) and the display panel to control the power supply, the convenience and operability of real-time detection of the disconnector status are improved, and the power consumption of real-time monitoring of the disconnector status is effectively reduced.

[0101] In one feasible implementation, the steps of stopping the turntable and displaying the corresponding status information specifically include: stopping the motor to stop the turntable from rotating; and displaying the status information on the turntable after it stops rotating, which corresponds to the observation window on the fixed plate.

[0102] When the battery (power supply) stops working, the motor stops rotating, and the turntable also stops rotating accordingly. When the turntable stops rotating, the status information in the corresponding display area on the turntable corresponds to the observation window on the fixed plate. The corresponding status information is displayed through the observation window, while other display areas on the turntable are obscured by parts of the fixed plate other than the observation window. The status information may include text indicating the status and corresponding colors. For example, the word "Open" and green on the turntable corresponding to the observation window indicate that the switch is in the open position; the word "Closed" and red on the turntable corresponding to the observation window indicate that the switch is in the open position; and the word "Abnormal" and yellow on the turntable corresponding to the observation window indicate that the switch is in an abnormal / working state.

[0103] By controlling the turntable with a motor to display the corresponding status information, a low-power real-time detection method for the switch status is achieved, which does not pose any safety hazards and is not affected by external power supply.

[0104] In this embodiment of the invention, the disconnect switch status detection system can detect the status of the disconnect switch without installing complex components such as transmission mechanisms on the primary equipment such as the disconnect switch. This means no modification to the primary equipment is required, making installation very convenient. Furthermore, maintaining a certain distance from the operating voltage of the disconnect switch avoids safety hazards caused by leakage faults, improving safety performance. Through the motor and turntable structure of the disconnect switch status detection system, powered by the power supply device within them, continuous power supply without external wiring is achieved. Its status detection is unaffected by the power supply of the transmission mechanism, and the power of the power supply device is only consumed when the status is being detected, thus effectively reducing the power consumption of real-time disconnect switch status monitoring. Without components such as chips that are susceptible to interference or damage, the overall robustness is strong. Because the core components are inexpensive and readily available, manufacturability is good. The overall structure is simple and does not require complex manufacturing processes.

[0105] Please see Figure 12 , Figure 12 This is a schematic diagram of another disconnector status detection method provided in an embodiment of the present invention, applied to the disconnector status detection system in the above embodiments. Another embodiment of the disconnector status detection method in this invention includes: 1201. The rotation position of the knife switch is detected by each sensing circuit, and the target detection circuit in at least two detection circuits is activated based on the rotation position.

[0106] The execution process of step 1201 is similar to that of steps 101 and 1101-1103 above, and will not be described again here.

[0107] 1202. When the control unit is in operation, the control display unit displays the corresponding status information and controls the power supply device to stop supplying power to the target detection circuit.

[0108] The execution process of step 1202 is similar to that of steps 102 and 1104 above, and will not be described again here.

[0109] 1203. The control unit controls the wireless communication circuit to be turned on, and sends the corresponding status information to the transceiver through the wireless communication circuit.

[0110] Optionally, the control unit (e.g., the controller) may send a connection command to the second on / off component at the corresponding position of the status information in the wireless communication circuit, so that the corresponding second on / off component is turned on, thereby turning on the wireless communication circuit. Here, the second on / off component is a control switch.

[0111] In one feasible implementation, step 1203 specifically includes: when the motor drives the turntable to rotate to the target position corresponding to the status information, the corresponding second on / off component is triggered to turn on the wireless communication circuit; the wireless communication circuit operates and sends the corresponding status information to the transceiver device based on wireless communication.

[0112] Specifically, for example, Figure 9 The circuit shown is illustrated using the target detection circuit as an example of the position detection circuit. When the turntable stops working, when the first trigger is driven to the first on / off component (normally closed micro switch) at the corresponding state position and the second trigger is driven to the second on / off component (normally open micro switch) at the corresponding state position, the first on / off component and the second on / off component are triggered, the position detection circuit (i.e., the target detection circuit) is disconnected, the wireless transceiver circuit in the wireless communication branch is turned on, and the wireless communication circuit is turned on.

[0113] The control unit triggers the second on / off component corresponding to the target detection circuit to conduct the wireless communication circuit, thereby converting the magnetically interfered current of the switch into a non-magnetically interfered current, thus not affecting wireless communication. It has strong anti-electromagnetic interference capability.

[0114] The controller in the wireless communication branch acquires the signal corresponding to the status information displayed on the display unit and transmits the signal to the transceiver device via an antenna. When the wireless transceiver circuit is activated, the microcontroller (the controller in the wireless communication branch) operates, instantly acquiring the electrical signal corresponding to the rotation position of the switch. The microcontroller then transmits this electrical signal to the transceiver device (backend) via an antenna. This enables wireless monitoring of the status of mechanisms such as the switch in complex electromagnetic environments.

[0115] If applied in environments with low electromagnetic interference, this solution only requires connecting the detection circuit of the circuit containing the motor and turntable in series as a wireless transceiver circuit with a microcontroller to achieve remote monitoring of valves and other equipment that are unattended for long periods but whose status needs to be monitored.

[0116] In this embodiment of the invention, the disconnect switch status detection system can detect the status of the disconnect switch without installing complex components such as transmission mechanisms on the primary equipment such as the disconnect switch. That is, no modification to the primary equipment is required, so the installation is very convenient. Moreover, by maintaining a certain distance from the operating voltage of the disconnect switch, the safety hazards caused by leakage faults can be avoided, thus improving safety performance. In addition, it can also avoid electromagnetic interference caused by the operating voltage of the disconnect switch, thereby having a wide range of applicability. Through wireless communication circuit, the system can monitor the status of the disconnect switch and other mechanisms wirelessly in complex electromagnetic environments.

[0117] The present invention also provides a disconnector status detection device, comprising: a memory and at least one processor, wherein the memory stores a computer program, and the memory and the at least one processor are interconnected via a line; the at least one processor calls the computer program in the memory to cause the disconnector status detection device to perform the steps in the disconnector status detection method described above.

[0118] The present invention also provides a computer-readable storage medium, which can be a non-volatile computer-readable storage medium or a volatile computer-readable storage medium, wherein a computer program is stored in the computer program, and when the computer program is run on the computer, the computer performs the steps of the switch status detection method.

[0119] Those skilled in the art will clearly understand that, for the sake of convenience and brevity, the specific working processes of the systems, devices, and units described above can be referred to the corresponding processes in the foregoing method embodiments, and will not be repeated here.

Based on this understanding, the technical solution of the present invention, in essence, or the part that contributes to the prior art, or all or part of the technical solution, can be embodied in the form of a software product.
