[0002] The detection of the running state of high-voltage equipment is crucial for the safe and reliable operation of the power grid. In order to grasp the electrical insulation performance of the running equipment, the electrical parameters of the equipment such as voltage, current and electric field are usually measured to analyze whether the electrical parameters of the equipment are within the rated design range. This work has important practical value for production and operation and scientific research. The electric field is distributed in the space around the high-voltage equipment, and the amplitude and size change of the electric field can reflect the state of the equipment. If the electric field distribution around the equipment can be accurately measured, and the spatial electric field curve of the adjacent area of different voltage points is drawn, the insulation performance of the equipment can be well analyzed. Therefore, this technical field has received attention from relevant research institutions in recent years, and research has been carried out in the field of electric field sensors and test systems.

[0003] Currently, in the operation and scientific research of the power system, in order to measure the spatial electric field, the electric field sensor is usually fixed at the end of the insulating rod, and the operator holds the other side of the insulating rod to place the sensor at the measured spatial point for measurement. However, such a measurement method has the problems of large measurement deviation caused by shaking of the handheld sensor, low safety guarantee of personnel near high-voltage points, large physical consumption of handheld operation, and uncontrollable measurement of the sensor at the set position.

[0042] Measuring the spatial electric field of high-voltage equipment is of great value for detecting its operating status. Addressing the various problems existing in current high-voltage equipment spatial electric field measurement and detection technologies, this invention proposes an intelligent spatial electric field measurement test platform that combines four components: a DC voltage generator, a test sample placement platform with adjustable high-voltage equipment placement height, a measurement mechanism with a photoelectric electric field sensor as the core measuring device, enabling remote control of the sensor's longitudinal and lateral movement and remote transmission of detection data, and a test system control and data transmission backend. The measurement platform provided by this invention enables remote and intelligent programming control of the measurement process, avoiding the safety risks associated with manual sensor operation, saving manpower, and improving the measurement efficiency of insulation performance of high-voltage equipment. By sending control commands to the wireless motor control module that controls the sensor's measurement angle, lateral and longitudinal movement distance, the longitudinal measurement position of the electric field sensor can be stably adjusted remotely within the range of 0–500 cm, the lateral measurement position within 0–100 cm, and the measurement angle within 0–360°. This achieves accurate measurement of lateral and longitudinal electric field data at each measurement point, reducing measurement errors. Furthermore, through the wireless signal transmission modules of each unit, the system control backend can remotely control and receive measurement data. This invention has significant practical value and scientific significance for accurately understanding the spatial electric field distribution in the vicinity of high-voltage equipment, providing an important platform for power production measurement and power research.

[0043] To more safely, conveniently, and accurately measure the electric field distribution around high-voltage equipment during insulation performance testing, and to plot the spatial electric field curves of areas near different voltage points, thereby further analyzing the operating status and insulation performance changes of the equipment under high voltage, this invention proposes an intelligent spatial electric field measurement test platform. This platform mainly consists of four parts: a DC voltage generator, a high-voltage equipment placement platform, a measurement mechanism with a photoelectric electric field sensor as the core measuring device, capable of remotely controlling the longitudinal and lateral movement of the sensor and remotely transmitting detection data, and a test system control and data transmission backend.

[0044] like Figure 1 As shown, the present invention provides a space electric field measurement experimental device, which includes: a DC voltage generator (1), a photoelectric electric field sensor (8), an experimental system control platform (21), and an electric field data transmission module (11);

[0045] The DC voltage generator (1) is connected to the high-voltage device being measured via a high-voltage lead, and applies high-voltage signals of different degrees to the high-voltage device being measured;

[0046] The experimental system control platform (21) sends control commands to control the photoelectric electric field sensor (8) to move in the first direction. The photoelectric electric field sensor (8) measures the first electric field data of the measurement point of the high voltage device being measured during the movement in the first direction. The first electric field data is sent to the data analysis system through the electric field data transmission module (11) until the moving distance of the photoelectric electric field sensor (8) reaches the first direction measurement distance threshold.

[0047] The experimental system control platform (21) sends control commands to control the measurement angle of the photoelectric electric field sensor (8). After adjusting the measurement angle of the photoelectric electric field sensor (8), the control commands of the experimental system control platform (21) control the photoelectric electric field sensor (8) to move in the second direction. The photoelectric electric field sensor (8) measures the second electric field data of the measurement point of the high voltage device being measured during the movement in the second direction. The second electric field data is sent to the data analysis system through the electric field data transmission module (11) until the moving distance of the photoelectric electric field sensor (8) reaches the second direction measurement distance threshold.

[0048] The data analysis system determines the spatial electric field distribution of the measured high-voltage device based on the first electric field data and the second electric field data.

[0049] The DC voltage generator (1) of this invention is connected to the high-voltage device being measured via a high-voltage lead, and is mainly used to apply high-voltage signals of different degrees to the high-voltage device being tested. The high-voltage device placement platform is mainly used to place and fix the high-voltage device being tested, and the lifting and lowering of the test sample base can be controlled by a hydraulic drive system and a wireless remote control module, thereby adjusting the placement height of the high-voltage device being tested. In the measurement mechanism with a photoelectric electric field sensor as the core measuring device, the overall support frame of the measurement mechanism is mainly made of insulating material. The photoelectric electric field sensor (8) is fixed to the end of the insulating support rod, and its detection signal is transmitted through the optical fiber inside the insulating support rod. An insulating support rod, a stepper motor, a motor control module, and a wireless field data transmission module are fixed on the sensor lifting platform. The stepper motor includes a push rod stepper motor that controls the adjustment of the sensor's X-axis (lateral) measurement distance and a rotary stepper motor that controls the sensor's measurement angle. The electric field measurement data is transmitted to the experimental system control platform (21) via the electric field data transmission module through an optical fiber. The lifting platform of the photoelectric electric field sensor (8) is fixed on a belt that is vertically fitted onto a pulley. The stepper drive motor controlled by the motor drive controller drives the belt through the control pulley to realize the X-axis (longitudinal) movement of the sensor and complete the adjustment of the sensor's measurement height. The experimental system control platform (21) can be programmed and the remote control module can send pre-set action commands to each motor to control the sensor's action flow during the measurement process. The experimental system control and data transmission backend is mainly composed of the experimental system control platform (21) and the data transmission and remote control module (22). It is mainly used to receive and analyze electric field measurement data and send control commands to the hydraulic drive system that controls the placement height of high-voltage equipment and the motor control module that controls the lateral and longitudinal movement of the photoelectric electric field sensor (8).

[0050] The photoelectric electric field sensor (8) of the present invention adopts a photoelectric low distortion rate electric field sensor, which is made of non-metallic composite material and artificial synthetic crystal material. The overall size of the sensor is small. Therefore, compared with the conventional metal capacitive electric field probe with a distortion rate of more than 20%, the distortion influence value of this sensor on the measured electric field is less than 5%.

[0051] Preferably, the first direction is horizontal, and the measurement distance threshold for the first direction is 100cm; the second direction is vertical, and the measurement distance threshold for the second direction is 500cm; the moving speed of the photoelectric electric field sensor is within 10cm / min.

[0052] The photoelectric electric field sensor (8) measures an angle range of 0 to 360°.

[0053] The position of the photoelectric electric field sensor (8) of the present invention can be controlled to move within a longitudinal height range of 0 to 500 cm and a lateral distance range of 0 to 100 cm, and its longitudinal and lateral movement speeds are adjustable within a range of 0 to 10 cm / min. The measurement angle of the sensor is adjustable within a range of 0 to 360°.

[0054] Preferably, the high voltage device to be measured is placed on the lifting platform of the high voltage device sample base, and the height adjustment range of the high voltage device to be measured is 0-200cm.

[0055] The high voltage device under test of the present invention can be height adjusted by a lifting platform controlled by a hydraulic drive system according to the safe operating height on site, and the adjustment range is 0 to 200 cm.

[0056] The photoelectric electric field sensor (8) and DC voltage generator (1) of the present invention apply a voltage range of 500kV.

[0057] The voltage applied by the high-voltage device of the present invention can be adjusted arbitrarily within the range of 0 to 500kV.

[0058] Preferably, the device is also used to perform:

[0059] Step S1: The experimental system control platform (21) sends a control command to control the photoelectric electric field sensor (8) to move in the first direction. The photoelectric electric field sensor (8) stops at the first lateral distance. After a preset time interval, the first electric field data at the first lateral distance of the high voltage device being measured during the movement in the first direction is measured. The first electric field data is sent to the data analysis system through the electric field data transmission module (11).

[0060] Step S2: The experimental system control platform (21) sends a control command to control the measurement angle of the photoelectric electric field sensor (8). After adjusting the measurement angle of the photoelectric electric field sensor (8), the control command of the experimental system control platform (21) controls the photoelectric electric field sensor to move in the second direction. The photoelectric electric field sensor (8) stops at the first longitudinal distance. After stopping for a preset time interval, the second electric field data at the first longitudinal distance of the high voltage device being measured during the movement in the second direction is measured. The second electric field data is sent to the data analysis system through the electric field data transmission module (11). After the photoelectric electric field sensor (8) stops for a preset time interval, the experimental system control platform (21) sends a control command to control the measurement angle of the photoelectric electric field sensor. After adjusting the measurement angle of the photoelectric electric field sensor (8), steps S1 and S2 are executed repeatedly until the moving distance of the photoelectric electric field sensor (8) reaches the first direction measurement distance threshold or the moving distance of the photoelectric electric field sensor (8) reaches the second direction measurement distance threshold.

[0061] The sensor measurement process of this invention can be programmed and controlled through a system control platform. For example, after the measurement platform starts, the electric field measurement sensor can be set to move upward to 20cm and stop, pause for 2 seconds, then first measure the X-direction (lateral) electric field value and send the data, then measure the Y-direction (longitudinal) electric field value by rotating the sensor's measurement angle and send the data, then pause for 4 seconds to reset the sensor's measurement angle, and then continue to move upward 20cm to measure the next point, and so on.

[0062] The test system control and data transmission backend of the present invention can receive measurement data through the electric field data transmission module, and send control commands to the hydraulic drive system and the stepper motor that controls the horizontal and vertical movement of the sensor through the data transmission and remote control module.

[0063] This invention provides an intelligent spatial electric field measurement and testing device that enables remote control of the measurement process, avoiding the safety risks associated with operators holding sensors close to high-voltage points. The invention uses a wireless motor control module to send control commands to the sensor's measurement angle, lateral and longitudinal movement distance, stabilizing the sensor's measurement position and angle. This ensures accurate measurement of lateral and longitudinal electric field data at each measurement point, reducing measurement errors. The device offers diverse measurement functions, allowing for flexible setting and control of the sensor's measurement process through programming. This enables fully automated and controllable measurement, saving manpower and improving the efficiency of measuring the insulation performance of high-voltage equipment.

[0064] The working principle and structural schematic diagram of the intelligent spatial electric field measurement and testing device proposed in this invention are shown below. Figure 1 As shown, it mainly consists of four parts: Part I: a 500kV DC voltage generator; Part II: a high-voltage equipment placement platform; Part III: a measurement mechanism with a photoelectric electric field sensor as the core measuring device, which can remotely control the longitudinal and lateral movement of the sensor and remotely send detection data; and Part IV: a test system control and data transmission backend.

[0065] In Part I, a 500kV DC voltage generator (1) is connected to the support insulator (3) of the high-voltage equipment being measured via a high-voltage lead (2) to apply high-voltage signals of different degrees to the high-voltage equipment being tested.

[0066] In Part II, the post insulator (3) being measured is fixed on the test sample base lifting platform (4). The height of the test sample base lifting platform (4) can be controlled by receiving control signals through the hydraulic drive system signal receiver (6) and the hydraulic drive system (5).

[0067] In Part III, the overall support frame (7) of the measuring mechanism is made of insulating material. The photoelectric electric field sensor (8) is fixed to the end of the insulating support rod (9). The insulating support rod (9), the stepper motor (10), the electric field data transmission module (11), and the control signal receiving and motor control module (12) are fixed together on the sensor lifting platform (13). The electric field data measured by the photoelectric electric field sensor (8) is transmitted to the electric field data transmission module (11) through the optical fiber (14) inside the insulating support rod (9). The stepper motor (10) includes a push rod stepper motor that controls the X-axis (lateral) movement of the sensor and a rotary stepper motor that controls the sensor's measurement angle. The sensor lifting platform (13) is fixed on the belt (16) that is vertically fitted onto the pulley (15). The pulley (15) below is connected in sequence to the stepper drive motor (17), the motor drive controller (18), and the motor control signal receiver (19). The motor control signal receiver (19) can send a working command to the motor drive controller (18) to control the stepper drive motor (17) to drive the pulley (15) and the belt (16) to rotate, thereby enabling the sensor (8) to adjust the measurement height according to the scale (20).

[0068] In Part IV, the test system control and data transmission backend mainly consists of a system control platform (21) and a data transmission and remote control module (22). It is mainly used by the backend staff to receive and analyze the electric field data measured by the photoelectric electric field sensor (8), as well as to send control commands to the hydraulic drive system (5) that controls the height of the sample base lifting platform and the control modules of the stepper motors (10) and (17) that control the horizontal and vertical movement of the sensor.

[0069] In this invention, the post insulator to be measured is fixed on the lifting platform of the test specimen base, and the test system control platform sends a control command to the hydraulic drive system to control the test specimen base to raise the post insulator to a certain height. Then, the high voltage lead of the 500kV DC voltage generator is connected to the post insulator.

[0070] This invention applies high voltage to the post insulator. The operator, through the test system control and data transmission backend, sends the programmed instructions for setting the sensor's actions to the control signal receiver of the stepper motor controlling the sensor's movement. This causes the electric field measurement sensor to operate according to the following instructions: First, the stepper motor on the sensor's lifting platform is controlled to maintain a lateral distance of 20cm between the sensor and the insulator being measured. Then, the stepper drive motor driving the belt is controlled to move the sensor upwards to 20cm and stop. After a 2-second pause, the rotating stepper motor is controlled to adjust the sensor's measurement angle. First, the X-axis (lateral) electric field value is measured and transmitted. Then, the Y-axis (longitudinal) electric field value is measured and transmitted by adjusting the sensor's measurement angle. After another 4-second pause to reset the sensor's measurement angle, it continues to move upwards by 20cm to measure the next point. This process is repeated until every measurement point on the post insulator has been measured.

[0071] This invention analyzes the electric field measurement data received by the control and data transmission backend of the test system. To obtain more accurate measurement data, a new set of programming instructions for controlling the sensor's actions can be set and sent to the control signal receiver of the stepper motor that controls the sensor's actions, thus starting a new round of measurements.

[0076] Step 203: Send control commands through the experimental system control platform to control the measurement angle of the photoelectric electric field sensor. After adjusting the measurement angle of the photoelectric electric field sensor, control the photoelectric electric field sensor to move in the second direction through the control commands of the experimental system control platform.

After a preset time interval, the first electric field data at the first lateral distance of the high-voltage device being measured during the movement in the first direction is measured, and the first electric field data is sent to the data analysis system.

[0080] Step S2: The experimental system control platform sends a control command to control the measurement angle of the photoelectric electric field sensor. After adjusting the measurement angle of the photoelectric electric field sensor, the control command of the experimental system control platform controls the photoelectric electric field sensor to move in the second direction. The photoelectric electric field sensor stops at the first longitudinal distance. After a preset time interval, the second electric field data at the first longitudinal distance of the high-voltage device being measured during the movement in the second direction is measured, and the second electric field data is sent to the data analysis system. After the photoelectric electric field sensor stops for a preset time interval, the experimental system control platform sends a control command to control the measurement angle of the photoelectric electric field sensor. After adjusting the measurement angle of the photoelectric electric field sensor, steps S1 and S2 are executed repeatedly until the moving distance of the photoelectric electric field sensor reaches the first direction measurement distance threshold or the moving distance of the photoelectric electric field sensor reaches the second direction measurement distance threshold.
