Description

Technical Field

[0001] This utility model belongs to the field of power system monitoring technology, specifically relating to a calibration device for a 10kV voltage sensor. Background Technology

[0002] 10kV voltage sensors play a crucial role in power systems. Their core function is to monitor voltage levels in the power system in real time, accurately measure voltage values ​​in transmission lines, substations, distribution cabinets, and other equipment, and transmit this data to monitoring or control systems to ensure the safe, stable, and efficient operation of the power system.

[0003] Some existing 10kV voltage sensors are typically designed to be fixed, which makes it difficult to adjust their angle and orientation after installation. For some sensors that require multi-point calibration, the fixed angle and orientation after installation may complicate the calibration process. Multi-point calibration usually requires multiple measurements at different positions or angles to ensure the linearity and accuracy of the sensor throughout its operating range. If the sensor is not easy to adjust, the calibration results may not be comprehensive enough, and thus may fail to reflect the sensor's true performance under different conditions. Utility Model Content

[0004] The purpose of this invention is to provide a calibration device for a 10kV voltage sensor, which aims to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A calibration device for a voltage sensor includes a sensor body, a base, an insulating housing adapted to be installed on the inner wall of the base, and a wiring hole opened on the outer surface of the insulating housing.

[0007] The calibration mechanism includes a fixed plate disposed on the outside of the base, lugs arranged in a circumferential array on the outer surface of the fixed plate, a servo motor adapted to be installed at the center position of the outer surface of the fixed plate, a connecting column fixedly installed at the output end of the servo motor via a coupling, a sleeve fixedly connected to the other end of the connecting column, and a rotating shaft located inside the sleeve and used in conjunction with the base.

[0008] In a preferred embodiment of this utility model, a bearing sleeve is installed at the connection between the sleeve and the rotating shaft to cooperate with rotation, and the outer surface of the rotating shaft is fixedly connected to the outer surface of the base.

[0009] As a preferred embodiment of the present invention, the calibration mechanism further includes a flipping component that cooperates to flip the base in any direction, and a support component that cooperates to prevent the flipping component from tipping over.

[0011] In a preferred embodiment of this utility model, the outer surface of the ball is in sliding contact with the inner wall of the circular guide rail, and the inner surface of the fixed sleeve is fixedly connected to the outer surface of the rotating shaft.

[0012] As a preferred embodiment of this utility model, the support assembly includes a fixed segment fixedly installed on the surface of the fixed plate away from the top-inlet cylinder, a telescopic segment slidably connected to the inner wall of the fixed segment and used in conjunction with the circular guide rail, and a fixed rod fixedly sleeved on the outer surface of the output end of the top-inlet cylinder and used in conjunction with the telescopic segment.

[0023] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0024] Example

[0025] Reference Figures 1-4 This is an embodiment of the present invention, which provides a calibration device for a 10kV voltage sensor, comprising:

[0026] The sensor body 100 includes a base 101, an insulating housing 102 adapted to be installed on the inner wall of the base 101, and a wiring hole 103 opened on the outer surface of the insulating housing 102.

[0027] It should be noted that the sensor body 100 adopts a Description 10kV live display sensor. The base 101 is responsible for supporting the other components of the sensor body 100, and the insulating shell 102 is used to isolate the electrical components and ensure that the sensor body 100 operates safely in a high-voltage environment. The wiring hole 103 is used to connect the power cord and signal line of the sensor body 100.

[0028] The calibration mechanism 200 includes a fixed plate 201 disposed on the outside of the base 101, lugs 202 arranged in a circumferential array on the outer surface of the fixed plate 201, a servo motor 203 adapted to be installed at the center position of the outer surface of the fixed plate 201, a connecting post 204 fixedly installed on the output end of the servo motor 203 by a coupling, a sleeve 205 fixedly connected to the other end of the connecting post 204, and a rotating shaft 206 located inside the sleeve 205 and used in conjunction with the base 101.

[0029] It should be noted that when the servo motor 203 is turned on, the rotational power of the servo motor 203 is transmitted to the sleeve 205 through the connecting column 204, so that the sleeve 205 drives the rotating shaft 206 to rotate, and then drives the fixed base 101 and the insulating shell 102 to rotate synchronously, so as to achieve the effect of rotating and adjusting the sensor body 100.

[0030] Specifically, a rotating bearing sleeve is installed at the connection between the sleeve 205 and the rotating shaft 206, and the outer surface of the rotating shaft 206 is fixedly connected to the outer surface of the base 101.

[0031] Furthermore, the calibration mechanism 200 also includes a flipping component 207 that cooperates to flip the base 101 in any direction, and a support component 208 that cooperates to prevent the flipping component 207 from tipping over.

[0032] Preferably, the flipping assembly 207 includes a top-feed cylinder 207a adapted to be installed on the outer surface of the fixed plate 201, a circular guide rail 207b fixedly connected to the output end of the top-feed cylinder 207a, a ball bearing 207c disposed on the inner side of the circular guide rail 207b, an L-shaped rod 207d fixedly connected to the outer surface of the ball bearing 207c, and a fixing sleeve 207e fixedly connected to the other end of the L-shaped rod 207d and used in conjunction with the rotating shaft 206.

[0033] It should be further explained that the output end of the control cylinder 207a extends, driving the circular guide rail 207b to move linearly. Through the cooperation of the circular guide rail 207b and the ball bearing 207c, the L-shaped rod 207d rotates around the rotating shaft 206. Then, through the cooperation of the L-shaped rod 207d and the fixed sleeve 207e, the rotating shaft 206, the base 101 and the insulating shell 102 are rotated, so as to achieve the effect of rotating and adjusting the sensor body 100.

[0034] It should be noted that the outer surface of the ball 207c slides in contact with the inner wall of the circular guide rail 207b, and the inner surface of the fixed sleeve 207e is fixedly connected to the outer surface of the rotating shaft 206.

[0035] Furthermore, the support assembly 208 includes a fixed segment 208a fixedly installed on the surface of the fixed plate 201 away from the top-inlet cylinder 207a, a telescopic segment 208b slidably connected to the inner wall of the fixed segment 208a and used in conjunction with the circular guide rail 207b, and a fixed rod 208c fixedly sleeved on the outer surface of the output end of the top-inlet cylinder 207a and used in conjunction with the telescopic segment 208b.

[0036] The fixed segment 208a provides a sliding track for the telescopic segment 208b to ensure the stability of the support assembly 208. The telescopic segment 208b provides additional support for the circular guide rail 207b. The fixed rod 208c is used to transfer the thrust of the jacking cylinder 207a to the telescopic segment 208b, ensuring that the support assembly 208 and the flipping assembly 207 work together to prevent the circular guide rail 207b from shifting position.

[0037] Specifically, the outer end face of the telescopic segment 208b is fixedly connected to the outer surface of the circular guide rail 207b, and the inner surface of the fixed rod 208c on the side away from the jacking cylinder 207a is fixedly connected to the outer surface of the telescopic segment 208b.

[0038] In use, the fixing plate 201 is installed in a suitable position by means of the ear piece 202, and then the insulating shell 102 is installed in the base 101. The servo motor 203 is turned on, and the rotational power of the servo motor 203 is transmitted to the sleeve 205 through the connecting column 204, so that the sleeve 205 drives the rotating shaft 206 to rotate. Then, the rotating shaft drives the fixing base 101 and the insulating shell 102 to rotate synchronously, so as to achieve the effect of rotating and adjusting the sensor body 100.

[0039] The output end of the control cylinder 207a extends, driving the circular guide rail 207b to move linearly. Through the cooperation of the circular guide rail 207b and the ball bearing 207c, the L-shaped rod 207d rotates around the pivot 206. Then, through the cooperation of the L-shaped rod 207d and the fixed sleeve 207e, the pivot 206, the base 101, and the insulating shell 102 are flipped, so as to achieve the effect of flipping and adjusting the sensor body 100. The thrust of the control cylinder 207a is transmitted to the telescopic section 208b through the fixed rod 208c to prevent the circular guide rail 207b from shifting position.

[0040] In summary, through the cooperation between the components in the calibration mechanism 200, the sensor body 100 can still rotate 360 ​​degrees in all directions in the horizontal plane or flip at any angle in the vertical direction after installation, so as to perform precise calibration. This not only ensures the accuracy of multi-point measurement results, but also enables the sensor body 100 to adapt to more complex installation environments, so as to accurately reflect the true performance of the sensor body 100 under different conditions.
