Description

Technical Field

[0001] This invention relates to the field of high voltage testing technology, and in particular to a high voltage testing device and its control method. Background Technology

[0002] To ensure the safe operation of high-voltage transmission lines and high-voltage electrical equipment, it is usually necessary to monitor the high-voltage circuits in high-voltage transmission systems. In recent years, ultraviolet (UV) sensors have been commonly used for non-contact voltage detection of high-voltage circuits. Specifically, the corona discharge generated by partial discharge in high-voltage circuits can radiate ultraviolet light. UV sensors can collect the UV radiation emitted by the high-voltage circuits and convert it into electrical signals. These signals are then used by the control module to determine the status of the high-voltage circuits, thereby enabling the monitoring of high-voltage circuits in high-voltage transmission systems.

[0003] When using ultraviolet (UV) sensors, it is necessary to avoid obstructing the UV collection end of the sensor with debris. However, when using UV sensors outdoors for long-term monitoring of high-voltage circuits in high-voltage power transmission systems, wild birds may stop and nest near the UV sensors, requiring frequent manual maintenance to drive away the birds and clear debris. Summary of the Invention

[0004] One objective of this invention is to provide a high-voltage detection device that can automatically deter birds, requires minimal manual maintenance, and has low operating costs.

[0005] Another objective of this invention is to provide a control method for a high-voltage voltage detector, which can control the aforementioned high-voltage voltage detector to automatically drive away birds.

[0006] To achieve this objective, the present invention adopts the following technical solution:

[0007] Firstly, a high-voltage detection device is provided, comprising:

[0008] A housing having a communicating inner cavity and a transition cavity, wherein the end of the transition cavity away from the inner cavity has an opening communicating with the outside of the housing;

[0009] An ultraviolet sensor is connected to the housing and located inside the inner cavity, with the ultraviolet sensor's ultraviolet collecting end facing the opening.

[0010] A control module is located within the inner cavity and electrically connected to the ultraviolet sensor;

[0011] A power supply, wherein the power supply is disposed within the internal cavity and electrically connected to the control module; and...

[0012] A bird deterrent assembly includes a bird deterrent rod and a drive motor. The drive motor is connected to the housing and located within the inner cavity. The drive motor is also electrically connected to the control module. The bird deterrent rod is tractively connected to the drive end of the drive motor. The bird deterrent rod is spaced apart from the ultraviolet sensor, and one end of the bird deterrent rod points towards the opening. The drive motor is at least capable of driving the bird deterrent rod to move in the direction from the inner cavity to the transition cavity.

[0013] As a preferred technical solution of the high-voltage detection device, the bird-repelling assembly includes a plurality of bird-repelling rods, which are spaced apart around the ultraviolet sensor. The bird-repelling assembly also includes a sliding cylinder and a sliding rod. The sliding rod is fixed to the side of the ultraviolet sensor away from the opening and extends along the opposite direction of the inner cavity and the transition cavity. The sliding cylinder is slidably sleeved on the sliding rod. The plurality of bird-repelling rods are all fixedly connected to the sliding cylinder, and the drive motor is drivenly connected to the sliding cylinder.

[0014] As a preferred technical solution of the high voltage detection device, the drive motor is capable of outputting rotational motion, and the bird deterrent assembly further includes a gear and a rack. The gear is located at the drive end of the drive motor, the rack is meshed with the gear, and the rack extends along the opposite direction of the inner cavity and the transition cavity. The bird deterrent rod is fixedly connected to the rack.

[0015] As a preferred technical solution of the high-voltage detection device, the bird deterrent assembly further includes an elastic element connected between the rack and the housing. The elastic element can apply an elastic force to the rack, causing the rack to tend to move away from the opening.

[0016] As a preferred technical solution of the high voltage detection device, the bird deterrent assembly further includes a limiting slider and a limiting cylinder. The limiting cylinder is fixed to the housing, and the limiting slider is fixed to one end of the rack. The limiting slider is slidably connected to the inner wall of the limiting cylinder along the opposite direction of the inner cavity and the transition cavity. The elastic element is connected between the limiting slider and the housing inside the limiting cylinder.

[0017] As a preferred technical solution of the high-voltage detection device, the high-voltage detection device further includes a dust removal component, which includes a rotating shaft, a first fan blade, and a second fan blade. The rotating shaft is rotatably connected to the end of the housing away from the opening via a one-way bearing, and the two opposite ends of the rotating shaft are located in the inner cavity and outside the housing, respectively. The first fan blade and the second fan blade are both fixedly disposed on the rotating shaft, with the first fan blade located outside the housing and the second fan blade located in the inner cavity and on the side of the ultraviolet sensor away from the opening.

[0018] As a preferred technical solution of the high-voltage detection device, the dust removal assembly further includes a generator, which is located in the inner cavity on the side of the second fan blade facing the first fan blade. The generator includes a rotor and a stator. The rotor is fixed to the rotating shaft, and the stator is fixed to the housing and spaced apart on the outer periphery of the rotor. One of the rotor and the stator includes a winding, and the other includes a magnet. The winding is electrically connected to the power source.

[0019] As a preferred technical solution of the high-voltage voltage testing device, the high-voltage voltage testing device further includes a support rod, one end of which is connected to the housing, and the end of the rotating shaft located in the inner cavity is rotatably connected to the support rod.

[0020] In a preferred embodiment of the high-voltage detection device, the power source is located on the side of the second fan blade facing the first fan blade.

[0021] In a second aspect, a control method for a high-voltage detection device is provided, for controlling the high-voltage detection device as described in the first aspect above, the control method comprising:

[0022] When the control module detects that the stored power in the power supply is greater than a predetermined threshold, the control module controls the drive motor to work;

[0023] When the control module detects that the amount of electricity stored in the power supply is less than or equal to the predetermined threshold, the control module controls the drive motor to cut off the power.

[0024] The beneficial effects of this invention are as follows:

[0025] By including a bird deterrent component in the high-voltage detection device, and electrically connecting the drive motor of the bird deterrent component to the control module, the control module can control the start of the drive motor, thereby enabling the drive motor to at least drive the bird deterrent rod to move from the inner cavity to the transition cavity, so that the end of the bird deterrent rod pointing towards the opening moves toward the opening, thereby automatically driving away wild birds that may be staying in the transition cavity through the bird deterrent rod.

[0026] Furthermore, by having the housing have a connected inner cavity and a transition cavity, and the transition cavity has an opening for ultraviolet light to enter, and the ultraviolet sensor is placed in the inner cavity, the ambient light can be partially blocked by the side wall of the transition cavity. This increases the proportion of ultraviolet light radiated by the high-voltage circuit aligning with the opening in the ultraviolet light collected by the ultraviolet sensor, thereby reducing the influence of ambient light on the detection results of the ultraviolet sensor and improving the detection accuracy of the high-voltage power detection device.

[0041] To make the technical problems solved by the present invention, the technical solutions adopted, and the technical effects achieved clearer, the technical solutions of the embodiments of the present invention will be further described in detail below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0042] In the description of this invention, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0043] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0044] like Figure 1 and Figure 2 As shown, the present invention provides a high-voltage detection device 100, including a housing 1, an ultraviolet sensor 2, a control module (not shown), a power supply 4, and a bird deterrent assembly 5. The housing 1 has a connected inner cavity 11 and a transition cavity 12. The end of the transition cavity 12 away from the inner cavity 11 has an opening 120 communicating with the outside of the housing 1. The ultraviolet sensor 2 is connected to the housing 1 and located inside the inner cavity 11, with the ultraviolet collecting end 21 of the ultraviolet sensor 2 facing the opening 120. The control module is located inside the inner cavity 11 and electrically connected to the control module. The ultraviolet sensor 2 and the power supply 4 are located inside the inner cavity 11 and electrically connected to the control module. The bird deterrent assembly 5 includes a bird deterrent rod 50 and a drive motor 51. The drive motor 51 is connected to the housing 1 and located inside the inner cavity 11. The drive motor 51 is also electrically connected to the control module. The bird deterrent rod 50 is driven by the drive end of the drive motor 51. The bird deterrent rod 50 is spaced apart from the ultraviolet sensor 2 and one end of the bird deterrent rod 50 points to the opening 120. The drive motor 51 can at least drive the bird deterrent rod 50 to move in the direction from the inner cavity 11 to the transition cavity 12.

[0045] By including a bird deterrent assembly 5 in the high-voltage testing device 100, and electrically connecting the drive motor 51 of the bird deterrent assembly 5 to the control module, the drive motor 51 can be started by the control module. Thus, the drive motor 51 can at least drive the bird deterrent rod 50 to move from the inner cavity 11 to the transition cavity 12, so that the end of the bird deterrent rod 50 pointing towards the opening 120 moves toward the opening 120, thereby automatically driving away wild birds that may stay in the transition cavity 12 through the bird deterrent rod 50.

[0046] Furthermore, by having the housing 1 have a connected inner cavity 11 and a transition cavity 12, and the transition cavity 12 has an opening 120 for ultraviolet light to enter, and the ultraviolet sensor 2 is placed in the inner cavity 11, the ambient light can be partially blocked by the side wall of the transition cavity 12. This increases the proportion of ultraviolet light radiated by the high-voltage circuit aligned with the opening 120 in the ultraviolet light collected by the ultraviolet sensor 2, thereby reducing the influence of ambient light on the detection results of the ultraviolet sensor 2 and improving the detection accuracy of the high-voltage power detection device 100.

[0047] Furthermore, by setting up power supply 4, the high-voltage detector 100 can have the function of storing electricity, so that when the high-voltage detector 100 is unable to obtain power supply due to uncontrollable outdoor environment, power supply 4 can be used to maintain the normal operation of the high-voltage detector 100, so as to better realize the function of long-term and continuous monitoring of the status of high-voltage circuits in the high-voltage transmission system.

[0048] Optionally, the housing 1 located on the outer periphery of the transition cavity 12 can be formed as a trumpet-shaped structure with a reduced outer diameter component from the opening 120 to the inner cavity 11, so that the cross-sectional area of ​​the transition cavity 12 communicating with the inner cavity 11 is smaller, which can further reduce the possibility of debris entering the inner cavity 11 through the transition cavity 12. At the same time, it can make the diameter of the opening 120 larger, thereby.

[0049] Optionally, the ultraviolet sensor 2 can be fixedly connected to the housing 1 via a connection structure, so that the relative position of the ultraviolet sensor 2 and the opening 120 can be easily kept stable, thereby making it easier to keep the ultraviolet collection function of the ultraviolet sensor 2 on the area aligned with the opening 120 more stable.

[0050] Please combine Figure 3 As shown, optionally, the bird deterrent assembly 5 includes a plurality of bird deterrent rods 50, which are arranged at intervals around the ultraviolet sensor 2. By increasing the number of bird deterrent rods 50 included in the bird deterrent assembly 5, the effective area of ​​the bird deterrent assembly 5 can be increased, thereby improving the bird deterrent effect.

[0051] Furthermore, the bird deterrent assembly 5 also includes a sliding cylinder 52 and a sliding rod 53. The sliding rod 53 is fixed to the side of the ultraviolet sensor 2 away from the opening 120, and extends along the relative direction of the inner cavity 11 and the transition cavity 12. The sliding cylinder 52 is slidably sleeved on the sliding rod 53. Multiple bird deterrent rods 50 are all fixedly connected to the sliding cylinder 52, and the drive motor 51 is drivenly connected to the sliding cylinder 52. By fixing multiple bird deterrent rods 50 to the sliding cylinder 52, the relative posture between each bird deterrent rod 50 can be made more stable, so that the bird deterrent effect area of ​​the bird deterrent assembly 5 is more stable. By fixing the sliding rod 53 to the side of the ultraviolet sensor 2 away from the opening 120, and making the sliding cylinder 52 slidably sleeved on the sliding rod 53, the sliding cylinder 52 and the sliding rod 53 can limit the movement trajectory of the bird deterrent rods 50 relative to the ultraviolet sensor 2, thereby making the bird deterrent effect of the bird deterrent rods 50 on the area near the ultraviolet sensor 2 more stable.

[0052] Optionally, the drive motor 51 can be any type of motor capable of outputting rotational motion. The bird deterrent assembly 5 also includes a gear 54 and a rack 55. The gear 54 is located at the drive end of the drive motor 51, and the rack 55 is meshed with the gear 54. The rack 55 extends along the relative direction of the inner cavity 11 and the transition cavity 12. The bird deterrent rod 50 is fixedly connected to the rack 55. Thus, the rotational motion output by the drive motor 51 can be converted into linear motion through the gear 54 and the rack 55, so that the bird deterrent rod 50 can be driven by the drive motor 51 to move along the direction from the inner cavity 11 to the transition cavity 12.

[0053] In other embodiments, the drive motor 51 may also be a cylinder, linear motor, or the like that capable of outputting linear motion, so that the bird deterrent rod 50 can be moved from the inner cavity 11 to the transition cavity 12 by the drive motor 51.

[0054] In order to reset the bird deterrent rod 50 after it moves from the inner cavity 11 to the transition cavity 12, in an optional embodiment, the bird deterrent rod 50 can be reset by outputting a reverse rotational motion or linear motion through the drive motor 51.

[0055] like Figure 4 and Figure 5 As shown, in another optional embodiment, the bird deterrent assembly 5 may further include an elastic element 56 connected between the rack 55 and the housing 1. The elastic element 56 can apply an elastic force to the rack 55, causing the rack 55 to tend to move away from the opening 120. Thus, a drive motor 51 without a self-locking function after power failure can be used. After the drive motor 51 is powered off, the rack 55 can be pushed away from the opening 120 by the elastic element 56 to drive the bird deterrent rod 50 to reset.

[0056] Optionally, the bird deterrent assembly 5 also includes a limiting slider 57 and a limiting cylinder 58. The limiting cylinder 58 is fixed to the housing 1, and the limiting slider 57 is fixed to one end of the rack 55. The limiting slider 57 is slidably connected to the inner wall of the limiting cylinder 58 along the relative direction of the inner cavity 11 and the transition cavity 12. An elastic element 56 is connected between the limiting slider 57 and the housing 1 inside the limiting cylinder 58, so that the relative movement trajectory of the rack 55 relative to the housing 1 can be limited by the cooperation between the limiting slider 57 and the limiting cylinder 58. This makes it easier to keep the rack 55 in a connected state of meshing with the gear 54, and further improves the stability of the movement trajectory of the bird deterrent rod 50, thereby further improving the stability of the bird deterrent effect of the bird deterrent rod 50.

[0057] Optionally, the high-voltage detection device 100 further includes a dust removal assembly 6, which includes a rotating shaft 60, a first fan blade 61, and a second fan blade 62. The rotating shaft 60 is rotatably connected to the end of the housing 1 away from the opening 120 via a one-way bearing, and the two opposite ends of the rotating shaft 60 are located in the inner cavity 11 and outside the housing 1, respectively. The first fan blade 61 and the second fan blade 62 are both fixedly mounted on the rotating shaft 60, with the first fan blade 61 located outside the housing 1 and the second fan blade 62 located in the inner cavity 11 and on the side of the ultraviolet sensor 2 away from the opening 120, thereby preventing high voltage... When the voltage testing device 100 is used outdoors, it can use natural wind power to drive the first blade 61 to rotate, which in turn drives the shaft 60 and the second blade 62 to rotate. This allows the second blade 62 to agitate the air in the inner cavity 11, forming an airflow from the inner cavity 11 to the transition cavity 12 and then to the opening 120. This effectively blows impurities in the transition cavity 12 out of the housing 1 and prevents impurities outside the housing 1 from entering the transition cavity 12, thereby further reducing the impact of impurities on the ultraviolet sensor 2.

[0058] Optionally, the power supply 4 can be electrically connected to an external power supply circuit, or the high voltage detection device 100 can have the function of supplying power to the power supply 4.

[0059] When the high-voltage detector 100 has the function of supplying power to the power source 4, optionally, the dust removal assembly 6 also includes a generator 63. The generator 63 is located in the inner cavity 11 on the side of the second fan blade 62 facing the first fan blade 61. The generator 63 includes a rotor 631 and a stator 632. The rotor 631 is fixed to the rotating shaft 60, and the stator 632 is fixed to the housing 1 and spaced apart on the outer periphery of the rotor 631. One of the rotor 631 and the stator 632 includes a winding, and the other includes a magnet. The winding is electrically connected to the power source 4, so that the first fan blade 61 can be driven to rotate by natural wind power, thereby driving the rotor 631 to rotate relative to the stator 632, thereby generating current in the winding to charge the power source 4. This configuration can improve the cleanliness of the energy used by the high-voltage detector 100, and eliminates the need for additional wiring to connect the high-voltage detector 100 to an external circuit, thus reducing the installation difficulty of the high-voltage detector 100.

[0060] Understandably, generator 63 can be any existing generator 63 including stator 632 and rotor 631. When rotor 631 includes windings and stator 632 includes magnets, generator 63 is a DC generator 63. When rotor 631 includes magnets and stator 632 includes windings, generator 63 is an AC generator 63.

[0061] When the bird deterrent assembly 5 further includes a slide bar 53 as described in the aforementioned technical solution, the end of the rotating shaft 60 located in the inner cavity 11 can be rotatably connected to the end of the slide bar 53 away from the ultraviolet sensor 2, thereby enabling the slide bar 53 and the rotating shaft 60 to support each other, so that the relative postures of the slide bar 53 and the rotating shaft 60 with respect to the housing 1 are more stable.

[0062] Optionally, the high-voltage detection device 100 also includes a support rod 3, one end of which is connected to the housing 1. The end of the rotating shaft 60 located in the inner cavity 11 is rotatably connected to the support rod 3, so that the support rod 3 can support the end of the rotating shaft 60 located in the inner cavity 11, so that the relative posture of the rotating shaft 60 and the housing 1 is more stable.

[0063] When the bird deterrent assembly 5 further includes a slide bar 53 as described in the aforementioned technical solution, the end of the slide bar 53 away from the ultraviolet sensor 2 can also be fixedly connected to the support rod 3, thereby making the relative posture of the slide bar 53 and the housing 1 more stable.

[0064] Optionally, the power supply 4 is located on the side of the second fan blade 62 facing the first fan blade 61 to avoid interference between the power supply 4 and the second fan blade 62, the bird deterrent assembly 5, and the ultraviolet sensor 2. When the dust removal assembly 6 also includes a generator 63 as described in the foregoing technical solution, this arrangement also allows the power supply 4 to be closer to the winding.

[0065] This invention also provides a control method for a high-voltage detection device; please refer again to [the previous text]. Figure 2 and Figure 3 This control method is used to control the high-voltage detection device 100 as described in the foregoing technical solution. Specifically, the control method includes:

[0066] When the control module detects that the stored energy in the power supply 4 is greater than a predetermined threshold, the control module controls the drive motor 51 to work; when the control module detects that the stored energy in the power supply 4 is less than or equal to the predetermined threshold, the control module controls the drive motor 51 to be powered off.

[0067] Therefore, when the stored energy in the power supply 4 is greater than a predetermined threshold, the control module can control the drive motor 51 to work, so that the high-voltage detector 100 can automatically drive away birds. When the stored energy in the power supply 4 is less than or equal to the predetermined threshold, the control module can cut off the power to the drive motor 51, so that the high-voltage detector 100 can stop the automatic bird-driving work, so as to prioritize the power supply to the ultraviolet sensor 2, thereby ensuring the stability of the high-voltage detector 100's monitoring function of the high-voltage circuit status in the high-voltage transmission system.

[0068] Understandably, the predetermined threshold can be selected according to actual use and design requirements. For example, the predetermined threshold can be selected as 95%, 90%, 85%, 80%, 75%, 70%, 65%, 60%, 55%, 50%, 45%, or 40% of the maximum energy storage capacity of the power supply 4.

[0069] In addition, the control method for controlling the operation of the drive motor 51 by the control module can be adapted to the specific operating conditions of the drive motor 51.

[0070] For example, as described in the aforementioned technical solution, when the drive motor 51 drives the bird deterrent rod 50 to deter birds and reset by alternately outputting forward and reverse rotational or linear motion, if the stored power in the power supply 4 is greater than a predetermined threshold, the control module can control the drive motor 51 to alternately output forward and reverse rotational or linear motion.

[0071] As described in the aforementioned technical solution, when the bird deterrent assembly 5 also includes an elastic element 56, so that the bird deterrent rod 50 can be reset by the elastic element 56 after the drive motor 51 is powered off, when the stored power in the power supply 4 is greater than a predetermined threshold, the control module can control the power supply 4 to intermittently supply power to the drive motor 51, so that the drive motor 51 intermittently outputs rotational motion or linear motion, and when the drive motor 51 is powered off, the bird deterrent rod 50 can be reset by the elastic element 56.
