Description

Technical Field

[0001] This utility model relates to the field of partial discharge detection technology, and more specifically, to an adsorption-type ultra-high frequency partial discharge detection device. Background Technology

[0002] Partial discharge is a common phenomenon in the insulation system of power equipment, which can lead to a decrease in the insulation performance of the equipment and even cause equipment failure. Ultra-high frequency sensors are an effective tool for detecting partial discharge and can capture the ultra-high frequency electromagnetic wave signals generated by partial discharge.

[0003] Traditional UHF sensors typically need to be installed directly inside or outside power equipment, which can lead to sensor displacement due to improper installation or equipment vibration, affecting detection accuracy. In addition, traditional sensor installation methods may require a complex installation process, increasing the difficulty and cost of field work. Utility Model Content

[0004] The present invention aims to provide an adsorption-type ultra-high frequency partial discharge detection device to solve the problems of complex installation, improper positioning, easy displacement due to vibration, and poor detection accuracy of existing ultra-high frequency sensors.

[0005] The embodiments of this utility model are implemented as follows:

[0006] This utility model provides an adsorption-type ultra-high frequency partial discharge detection device, which includes a control component, a detection component, a display component, a communication component, and an adsorption component for extending and adsorbing onto an electrical device. The control component is electrically connected to the detection component, the display component, the communication component, and the adsorption component.

[0007] The aforementioned adsorption assembly includes a suction cup, a telescopic member, and a motor. One end of the telescopic member is connected to the motor, and the other end of the telescopic member is connected to the suction cup. The motor is electrically connected to the control assembly.

[0008] In use, the control component controls the motor of the adsorption component to drive the telescopic component to extend and retract, so that the suction cup extends and adsorbs onto the surface of the equipment, thereby achieving specific position adjustment. The detection component collects the partial discharge signal of the on-site power equipment and outputs it to the control component. The control component filters, reduces noise, and amplifies the signal, and displays the signal value on the display component. Then, it is output to the partial discharge analysis platform through the communication component.

[0009] The adsorption-type ultra-high frequency partial discharge detection device disclosed in this embodiment, due to the adsorption component mentioned above, enables the detection device to be adsorbed onto the surface of electrical equipment, avoiding displacement of the detection equipment and affecting the accuracy of the detection. Thus, the adsorption-type ultra-high frequency partial discharge detection device has the beneficial effects of simple installation, suitable installation location, no displacement of the detection equipment, and high detection accuracy.

[0010] Optionally, the control component includes a telescopic switch, an adsorption switch, and a circuit board, wherein the telescopic switch and the adsorption switch are electrically connected to the circuit board.

[0011] With this configuration, the telescopic switch can control the extension of the telescopic component. Since the surfaces of the GIS pipe and the basin insulator are curved, the UHF sensor cannot be fixedly connected by placing it directly on them. Therefore, after the telescopic switch is turned on, the suction cup can extend from inside the housing and adhere to the surface of the equipment. The motor stably adheres to it, thereby fixing the position of the UHF sensor.

[0012] Optionally, the display component has a display screen, which is electrically connected to the control component.

[0013] With this configuration, the display screen is connected to the circuit board. The display screen shows the data of the collected signals, and can also show the control status of the adsorption component and the power of the motor, thereby realizing the control of the suction force and extension length of the adsorption component.

[0014] Optionally, the communication component described above has a coaxial interface and a wireless unit, both of which are electrically connected to the control component.

[0015] With this configuration, the ultra-high frequency sensor collects partial discharge signals and transmits them to a partial discharge analyzer or oscilloscope via the aforementioned coaxial interface. The wireless unit is used to wirelessly connect to the aforementioned adsorption component, enabling contactless control of the length of the adsorption component extending from the aforementioned housing and the power of the aforementioned motor, ensuring that the ultra-high frequency sensor can be stably adsorbed onto the surface of the power equipment.

[0016] Optionally: The telescopic member has a plurality of circular tubes connected in sequence, the circular tube near the motor is fixedly connected to the motor, the circular tube near the suction cup is fixedly connected to the suction cup, and the diameter of the plurality of circular tubes decreases gradually from the motor to the suction cup and is interlocked and sealed to each other.

[0017] With this configuration, the arrangement of several of the aforementioned circular tubes allows the telescopic component to control the length of its extension from the housing, thereby adjusting the position of the UHF sensor on site. Furthermore, the sealed connection structure ensures that the suction cup can be stably adsorbed onto the surface of the equipment.

[0018] Optionally, it also includes a housing, wherein the control component and the detection component are both disposed inside the housing, the communication component and the display component are disposed on the housing, and the adsorption component is disposed inside the housing and can extend to the outside of the housing.

[0019] With this configuration, the display screen of the display component is mounted on the outer surface of the housing, the adsorption switch and the telescopic switch of the control component are arranged vertically and located on one side of the display screen, the coaxial interface of the communication component is provided on the adjacent side of the display screen, and the adsorption component and the circuit board are located inside the housing, which facilitates the adsorption equipment to perform detection.

[0020] Optionally: the housing is a cuboid structure, the interior of the housing has a cavity, one side of the housing is provided with an opening and closing member, and the suction cup of the adsorption assembly corresponds to the opening and closing member.

[0021] With this configuration, by opening or closing the aforementioned opening and closing components, the suction cup of the aforementioned adsorption component can extend or retract into the aforementioned housing, facilitating the adsorption of the detection device onto the equipment for detection. When not in use, closing the aforementioned opening and closing components can keep the interior of the aforementioned housing sealed, preventing dust from entering the aforementioned cavity of the aforementioned housing and preventing damage to the aforementioned detection component inside the aforementioned cavity.

[0022] Optionally: the above-mentioned opening and closing component has an opening and closing hole, a connecting plate, a connecting block, and a limiting groove;

[0023] The aforementioned opening and closing hole is located on the side of the aforementioned housing. The aforementioned suction cup extends retractably out of the exterior of the aforementioned housing through the aforementioned opening and closing hole. The aforementioned connecting block is located on one side of the aforementioned opening and closing hole. The aforementioned connecting plate is located inside the aforementioned opening and closing hole and is rotatably connected to the aforementioned connecting block. The aforementioned limiting groove is located on the same side of the aforementioned housing as the aforementioned opening and closing hole and is snapped together with the aforementioned connecting plate.

[0024] With this configuration, when the detection component needs to perform a detection, the connecting plate is pulled out of the opening and closing hole and snapped into the limiting groove. At this time, the suction cup of the adsorption component can extend out of the opening and closing hole to adsorb the device. When the detection component does not need to perform a detection, the suction cup of the adsorption component retracts into the interior of the housing, and the connecting plate rotates along the connecting block and is embedded in the opening and closing hole, so that the housing is sealed, preventing the internal structure of the housing from being exposed and preventing dust from entering the interior of the housing.

[0025] Optionally: The connecting plate has a limiting block on its side, the limiting block and the limiting groove are symmetrically arranged, and the limiting block is snapped into the limiting groove.

[0026] With this configuration, the limiting block is pulled open, and the connecting block is rotated to the limiting groove on one side for limiting, so that the connecting plate is fixed on one side of the opening and closing hole.

[0027] Optionally: The above detection components have an ultra-high frequency sensor.

[0028] With this configuration, the ultra-high frequency (UHF) sensor is an effective tool for detecting partial discharge. It can capture the UHF electromagnetic wave signal generated by partial discharge. By placing the UHF sensor inside the aforementioned housing, it avoids direct installation of the UHF sensor inside or outside the power equipment, effectively preventing the UHF sensor from shifting due to equipment vibration. At the same time, this arrangement makes the UHF sensor detection more accurate.

[0029] In summary, the beneficial effects of the adsorption-type ultra-high frequency partial discharge detection device disclosed in this utility model are as follows: The adjustable-length adsorption component, in conjunction with the housing structure, can be tightly adsorbed onto the surface of the power equipment, reducing sensor displacement caused by equipment vibration or movement and improving detection accuracy; the adsorption installation method simplifies the sensor installation process, reducing the difficulty and cost of on-site work; the adjustable-length telescopic component allows the adsorption component to extend outside the housing and adsorb onto the equipment, adjusting the sensor distance, expanding the sensor's detection range, and making the installation position more suitable.

Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. The components of the embodiments of this utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0038] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0039] Example

[0040] See Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 This embodiment proposes an adsorption-type ultra-high frequency partial discharge detection device, including a control component 1, a detection component (not shown in the figure), a display component 2, a communication component 3, and an adsorption component 4 for extending and adsorbing onto an electrical device. The control component 1 is electrically connected to the detection component, the display component 2, the communication component 3, and the adsorption component 4.

[0041] The adsorption component 4 has a suction cup 5, a telescopic component 6 and a motor 7. One end of the telescopic component 6 is connected to the motor 7, and the other end of the telescopic component 6 is connected to the suction cup 5. The motor 7 is electrically connected to the control component 1.

[0042] In use, the control component 1 controls the motor 7 of the adsorption component 4 to drive the telescopic component 6 to extend and retract, so that the suction cup 5 extends and adsorbs onto the surface of the equipment, thereby achieving specific position adjustment. The detection component collects the partial discharge signal of the on-site power equipment and outputs it to the control component 1. The control component 1 filters, reduces noise, and amplifies the signal, and displays the signal value on the display component 2. Then, it outputs it to the partial discharge analysis platform through the communication component 3.

[0043] The adsorption-type ultra-high frequency partial discharge detection device disclosed in this embodiment is equipped with an adsorption component 4, which allows the detection device to be adsorbed onto the surface of electrical equipment, avoiding displacement of the detection equipment and affecting the accuracy of the detection. As a result, the adsorption-type ultra-high frequency partial discharge detection device has the beneficial effects of simple installation, suitable installation location, no displacement of the detection equipment, and high detection accuracy.

[0044] See Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 The control component 1 has a telescopic switch 8, an adsorption switch 9, and a circuit board (not shown in the figure). The telescopic switch 8 and the adsorption switch 9 are electrically connected to the circuit board. The telescopic switch 8 can control the extension of the telescopic component 6. Because the surface of the GIS pipe and the basin insulator is arc-shaped, the UHF sensor cannot be fixedly connected by directly placing it on it. Therefore, after the telescopic switch 8 is turned on, the suction cup 5 can extend from inside the housing 13 and adsorb onto the surface of the equipment. The motor 7 stably adsorbs onto it, thereby fixing the position of the UHF sensor.

[0045] The display component 2 has a display screen 10, which is electrically connected to the control component 1 and connected to the circuit board. The display screen 10 displays the data of the acquired signals and can also display the control status of the adsorption component 4 and the power of the motor 7, thereby realizing the control of the suction force and extension length of the adsorption component 4.

[0046] The communication component 3 has a coaxial interface 11 and a wireless unit (not shown in the figure). Both the wireless unit and the coaxial interface 11 are electrically connected to the control component 1. The ultra-high frequency sensor collects partial discharge signals and transmits them to a partial discharge analyzer or oscilloscope through the coaxial interface 11. The wireless unit is used to wirelessly connect to the adsorption component 4, which can control the length of the adsorption component 4 extending out of the housing 13 and the power of the motor 7 without contact, ensuring that the ultra-high frequency sensor can be stably adsorbed on the surface of the power equipment.

[0047] The telescopic component 6 has several circular tubes 12 connected in sequence. The circular tube 12 near the motor 7 is fixedly connected to the motor 7, and the circular tube 12 near the suction cup 5 is fixedly connected to the suction cup 5. The diameter of the circular tubes 12 decreases segment by segment from the motor 7 to the suction cup 5 and they are interlocked and sealed together. The arrangement of the circular tubes 12 allows the telescopic component 6 to control the length of the extension of the housing 13, which is used to adjust the position of the UHF sensor on site. The sealed connection structure ensures that the suction cup 5 can be stably adsorbed on the surface of the equipment.

[0048] See Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 It also includes a housing 13, with the control component 1 and the detection component both located inside the housing 13. The communication component 3 and the display component 2 are located on the housing 13. The adsorption component 4 is located inside the housing 13 and can be extended to the outside of the housing 13. The display screen 10 of the display component 2 is mounted on the outer surface of the housing 13. The adsorption switch 9 and the extension switch 8 of the control component 1 are arranged vertically and located on one side of the display screen 10. The coaxial interface 11 of the communication component 3 is provided on the adjacent side of the display screen 10. The adsorption component 4 and the circuit board are located inside the housing 13 to facilitate the adsorption equipment to perform detection.

[0049] The housing 13 has a cuboid structure and an internal cavity 14. An opening and closing member 15 is provided on one side of the housing 13. The suction cup 5 of the adsorption component 4 corresponds to the opening and closing member 15. By opening or closing the opening and closing member 15, the suction cup 5 of the adsorption component 4 can extend or retract from the housing 13, making it easy to adsorb the detection device onto the equipment for detection. When not in use, closing the opening and closing member 15 can keep the inside of the housing 13 sealed, preventing dust from entering the cavity 14 of the housing 13 and preventing damage to the detection component inside the cavity 14.

[0050] See Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 The opening and closing component 15 has an opening and closing hole 16, a connecting plate 17, a connecting block 18, and a limiting groove 19;

[0051] The opening and closing hole 16 is formed on the side of the housing 13. The suction cup 5 extends retractably out of the housing 13 through the opening and closing hole 16. The connecting block 18 is set on one side of the opening and closing hole 16. The connecting plate 17 is set in the opening and closing hole 16 and is rotatably connected to the connecting block 18. The limiting groove 19 is set on the same side of the housing 13 as the opening and closing hole 16 and is snapped to the connecting plate 17. When the detection component needs to detect, the connecting plate 17 is pulled out from the opening and closing hole 16 and snapped onto the limiting groove 19. At this time, the suction cup 5 of the adsorption component 4 can extend out of the opening and closing hole 16 to adsorb the device. When the detection component does not need to detect, the suction cup 5 of the adsorption component 4 is retracted into the housing 13. The connecting plate 17 rotates along the connecting block 18 and is embedded in the opening and closing hole 16, so that the housing 13 is sealed, preventing the internal structure of the housing 13 from being exposed and preventing dust from entering the interior of the housing 13.

[0052] The connecting plate 17 has a limiting block 20 on its side. The limiting block 20 and the limiting groove 19 are symmetrically arranged. The limiting block 20 is snapped into the limiting groove 19. When the limiting block 20 is pulled out, it is rotated into the limiting groove 19 on one side by the connecting block 18 for limiting, so that the connecting plate 17 is fixed on one side of the opening and closing hole 16.

[0053] The detection component has an ultra-high frequency sensor (not shown in the figure). The ultra-high frequency sensor is an effective tool for detecting partial discharge. It can capture the ultra-high frequency electromagnetic wave signal generated by partial discharge. The ultra-high frequency sensor is arranged inside the housing 13 to avoid the ultra-high frequency sensor being directly installed inside or outside the power equipment. This effectively prevents the ultra-high frequency sensor from shifting due to equipment vibration. At the same time, this arrangement makes the ultra-high frequency sensor detection more accurate.

[0054] See Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 In this embodiment, the adjustable-length adsorption component 4, in conjunction with the housing 13, can be tightly adsorbed onto the surface of the power equipment, reducing sensor displacement caused by equipment vibration or movement and improving detection accuracy. The adsorption installation method simplifies the sensor installation process and reduces the difficulty and cost of on-site work. The adjustable-length telescopic component 6 allows the adsorption component 4 to extend outside the housing 13 and adsorb onto the equipment, adjusting the sensor distance and expanding the sensor's detection range, making the installation position more suitable.

[0055] See Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 The specific working principle of the adsorption-type partial discharge ultra-high frequency detection device in this embodiment is as follows:

[0056] First, pull open the limiting block 20 and rotate it through the connecting block 18 into the limiting groove 19 on one side, so that the connecting plate 17 is fixed to one side of the opening and closing hole 16. Press the telescopic switch 8, and control the suction cup 5 to extend out of the housing 13 from the opening and closing hole 16 through the circuit board. The length of the telescopic component 6 extending out of the housing 13 can be remotely controlled through the wireless unit. Then, press the adsorption switch 9, and the motor 7 starts to work, outputting power to the suction cup 5, so that the suction cup 5 is adsorbed on the surface of the equipment. The output power of the motor 7 can be controlled through the wireless unit. The detection component collects the partial discharge signal of the on-site power equipment and outputs it to the control component 1. The control component 1 filters, reduces noise, and amplifies the signal, and displays the signal value on the display component 2. Then, it is output to the partial discharge analysis platform through the communication component 3. Finally, the detection is completed. Press the adsorption switch 9 again or turn off the motor 7 at the remote control end. Press the telescopic switch 8, and the suction cup 5 returns to the inside of the housing 13. Pull the connecting plate 17 to the position of the opening and closing hole 16 to close the internal structure of the housing 13, thus realizing the partial discharge detection.

[0057] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art.
