[0003] In the prior art, Chinese patent CN218824556U discloses a partial discharge monitoring device for the interior of a high and low voltage switch cabinet, comprising an installation inner plate, an installation inner groove is provided on the upper surface of the installation inner plate, and a movable seat is movably connected to the inner wall of the installation inner groove. The partial discharge monitoring device for the interior of a high and low voltage switch cabinet comprises an installation inner plate located inside the cabinet, the movable seat is installed in the installation inner groove on the installation inner plate, the monitoring probe is fixed at the bottom of the movable seat, and a first electric push rod is fixed on a first fixed seat on the side of the cabinet, the top of the first electric push rod is connected to the lower surface of the installation inner plate, and the monitoring probe is connected to a discharge detector through a connecting line, so that the detection structure is directly installed inside the cabinet, and there is no need for the staff to hold the detector for detection, so that the probe monitors different monitoring areas inside the switch cabinet, reduces the contact between the staff and the switch cabinet, improves the safety of monitoring, and avoids casualties.

[0004] However, in actual use, the detection structure of the invention is installed inside the cabinet. Due to the large number of circuits and electronic components distributed inside the switch cabinet, the range of movement of the monitoring probe is limited. At the same time, mobile monitoring inside may conflict with the circuit, affecting the normal use of the switch cabinet. The monitoring probe is fixed on the mobile seat, and the discharge detector is connected to the electric push rod. When the detection device is damaged, it is not convenient to replace the detection device, which easily affects the accuracy of the detection data. Therefore, improvement is needed. The existing detection device is prone to detection failures and has a low degree of intelligence. Summary of the invention

[0017] By adopting the above technical solution, when the rotating sleeve rotates, the inner wall of the limit rotating groove and the blocking ring are fitted and rotated, and the second motor is started when rotation is required.

[0018] The present invention is further configured as follows: an output end of the second motor is fixedly connected to a motor shaft, a top of the motor shaft is fixedly connected to a turntable, and an outer surface of the turntable is fixedly connected to a rotating sleeve.

[0019] By adopting the above technical solution, the motor shaft drives the turntable to rotate, and the rotating sleeve realizes automatic rotation adjustment.

[0020] The present invention is further configured as follows: a threaded hole is provided at the bottom of the clamping plate, a receiving plate is provided at the bottom of the clamping plate, and bolts are connected to the internal threads of the receiving plate.

[0021] By adopting the above technical solution, after the clamping plate clamps the fixed block, the receiving plate is placed at the bottom of the clamping plate, and the bolts are extended to the inside of the fixed block to reinforce the fixed block.

[0026] The monitoring device of the present invention further comprises: a discharge detector, which comprises a voltage detection element for detecting voltage, a temperature sensor, a controller, and a transmission unit.

[0027] The discharge detector transmits the real-time detected data to the controller through the transmission unit. After the controller processes the data through the intelligent analysis module, it sends further monitoring logic to the corresponding control elements for monitoring.

[0028] Detection steps: First, start the monitoring preparation, input the cabinet size information into the controller, automatically divide the cabinet into multiple areas according to the input cabinet information, and set up a data storage package for each area; the information in the data storage package includes the dynamic voltage parameters and dynamic temperature parameters of each area.

[0029] The controller sends general monitoring instructions: by cooperating with the lifting track and the second telescopic rod, multi-point mobile monitoring in the vertical and horizontal directions is realized. The multi-point mobile monitoring is specifically as follows: for each area, within the set interval time, the corresponding real-time data is collected and transmitted to the controller; after the first round of information collection is completed in all areas of the cabinet, the initial information analysis step is executed.

[0030] The intelligent analysis module performs preliminary screening on the initial information to find out the information value that exceeds the warning threshold, and by judging the risk value of the information value, it executes alarm maintenance prompts or performs further screening steps.

[0031] Set the warning voltage threshold: V0, temperature threshold T0, and ultrasonic abnormal value prompt area.

[0032] Calculate the average value of multiple rounds of detection: Vp and Tp,

[0033] Conduct multiple rounds of monitoring and comparison on the detection voltage abnormal areas and temperature abnormal areas to find out the areas with abnormal voltage and temperature rise rates, analyze the overlap of abnormal areas in different rounds of monitoring data, and analyze the overlap between the ultrasonic abnormal value prompt area and the abnormal area.

[0034] When the real-time detected voltage value of a certain area is greater than or equal to the warning voltage threshold, or the real-time detected temperature value is greater than or equal to the temperature threshold, and the ultrasonic abnormal value prompt area coincides with this area, it indicates a high risk and requires shutdown maintenance.

[0035] When the real-time detected voltage value in a certain area is less than the warning voltage threshold value and greater than Vp, or the real-time detected temperature value is less than the temperature threshold value and greater than Tp, or there is an ultrasonic abnormal value prompt area, a medium-risk warning is prompted, and the abnormal area parameters need to be further analyzed: further collect multiple rounds of information, cooperate with the lifting track 3 and the second telescopic rod 9 to only collect information from the abnormal value prompt area, and compare the changes in each value in each round within the same time interval. If there are N consecutive time intervals, the temperature or voltage value continues to rise, or the ultrasonic wave continues to prompt abnormalities, then a high risk is prompted, otherwise, continue to perform multiple rounds of monitoring of the area. If the temperature is less than Tp and the voltage value is less than Vp within N+1 consecutive time intervals, perform full cabinet area monitoring and analyze potential risk areas. If a new medium-risk or higher area appears, continue to perform multiple rounds of detection and analysis for the area.

[0036] When the real-time detected voltage value in a certain area is less than the warning voltage threshold and less than Vp, or the real-time detected temperature value is less than the temperature threshold and less than Tp, or there is no ultrasonic abnormal value prompt area, it is prompted as a low-risk area and routine monitoring of the entire cabinet is performed.

For each area, set up a data storage package; the information in the data storage package includes the dynamic voltage parameters and dynamic temperature parameters of each area; The controller sends general monitoring instructions: by cooperating with the lifting track and the second telescopic rod, multi-point mobile monitoring in the vertical and horizontal directions is realized. The multi-point mobile monitoring is specifically as follows: for each area, within the set interval time, the corresponding real-time data is collected and transmitted to the controller; after the first round of information collection is completed in all areas of the cabinet, the initial information analysis step is performed; Step 7: The intelligent analysis module performs preliminary screening on the initial information to find out the information value that exceeds the warning threshold, and by judging the risk value of the information value, it performs alarm maintenance prompts or performs further screening steps; Set the warning voltage threshold: V0, temperature threshold T0, and ultrasonic abnormal value prompt area; Calculate the average value of multiple rounds of detection: Vp and Tp, Conduct multiple rounds of monitoring and comparison of abnormal voltage and temperature areas to find out areas with abnormal voltage and temperature rise rates, analyze the overlap of abnormal areas in different rounds of monitoring data, and analyze the overlap of abnormal ultrasonic value prompt areas with them; Step 8: When the real-time detected voltage value of a certain area is greater than or equal to the warning voltage threshold, or the real-time detected temperature value is greater than or equal to the temperature threshold, and the ultrasonic abnormal value prompt area coincides with this area, it indicates a high risk and requires shutdown maintenance; When the real-time detected voltage value of a certain area is less than the warning voltage threshold value and greater than Vp, or the real-time detected temperature value is less than the temperature threshold value and greater than Tp, or there is an ultrasonic abnormal value prompt area, a medium risk warning is prompted, and the abnormal area parameters need to be further analyzed: further collect multiple rounds of information, cooperate with the lifting track (3) and the second telescopic rod (9) to only collect information from the abnormal value prompt area, and compare the changes in each value in each round within the same time interval.
