Description

Technical Field

[0001] The present invention belongs to the technical field of high-voltage power transmission and transformation detection, and specifically relates to a device and method for measuring and detecting the surface charge of a high-voltage power transmission and transformation insulator. Background Art

[0002] High-voltage power transmission and transformation insulators are a special type of insulation control component that can play an important role in overhead transmission lines. They are mainly used in high-voltage and ultra-high-voltage overhead transmission lines and substations to meet the needs of different voltage levels. Charge detection heads are usually used to accurately measure the charge distribution on the surface of insulators. During measurement, the device is placed on the surface of the insulator and the position of the charge detection head is adjusted to cover the entire measurement area. Then, the measurement data is recorded and analyzed to obtain the charge on the surface of the insulator.

[0003] In the prior art, the authorization publication number "CN118465388B" discloses "a device and method for measuring the surface charge of a high-voltage power transmission and transformation insulator"; the device for measuring the surface charge of a high-voltage power transmission and transformation insulator makes the steps between two adjacent detection tasks only include lifting the flip plate, flipping the flip plate and lowering the flip plate, and the disassembly and assembly of the insulator can be completed during the measurement work. Compared with the prior art, the operation steps and time intervals between two adjacent insulator outer surface charge measurement tasks are greatly shortened, which is more conducive to large-scale detection work and greatly improves the detection efficiency. At the same time, since the disassembly and assembly of the insulator are all carried out on the outside of the detection chamber, human hands will not enter the inside of the detection chamber. Even if the power on the inside of the detection chamber is not cut off in time, it will not cause harm to people. Such a fool-proof setting effectively avoids electric shock when disassembling and assembling insulators.

[0004] The above-mentioned "a device and method for measuring the surface charge of a high-voltage power transmission and transformation insulator" still has some shortcomings. For example, due to the harsh environment and insufficient maintenance, dust, dirt and dust are easily accumulated on the surface of the insulator. The dirt will reduce the insulation performance of the insulator, increase dielectric loss and leakage current, and lead to increased energy loss. Before the existing charge measurement, it is often necessary to manually clean the surface of the insulator, which reduces the detection efficiency. At the same time, when the humidity is high, water molecules will form a tiny water film on the surface of the insulator. The water film reduces the electric field strength on the surface of the insulator, thereby inhibiting the accumulation of charge.

[0005] To this end, a device and method for measuring and detecting the surface charge of high-voltage power transmission and transformation insulators are proposed to solve the above-mentioned problems. Summary of the invention

[0006] In view of the above situation, in order to overcome the defects of the prior art, the present invention provides a surface charge measurement and detection device and method for high-voltage power transmission and transformation insulators, which effectively solves the problem that the surface of the insulator needs to be manually cleaned during detection in the current market, reducing the detection efficiency. At the same time, when the humidity is high, water molecules will form a tiny water film on the surface of the insulator. The water film reduces the electric field strength on the surface of the insulator, thereby inhibiting the accumulation of charge.

[0016] A method for using a device for measuring and detecting the surface charge of a high-voltage power transmission and transformation insulator comprises the following steps:

[0017] S1. First, the main electric push rod is used to start the top fixing ring, which is connected to the side support frame to drive the top fixing ring to move vertically. After the top fixing ring is driven to move to the highest position, the operator places the insulator body to be tested on the surface of the top fixing ring, and fixes the insulator body by passing the bolts through the threaded holes. After the fixation is completed, the top fixing ring is driven down by the main electric push rod. After the top fixing ring is lowered, it will drive the insulator body to enter the outer protection box along the top connecting port, and after the test is completed, the insulator body is pushed out by the main electric push rod;

[0018] S2. When the main electric push rod drives the insulator body to descend, the motor body is started at this time, and the motor body is started, and the side connecting rod is driven to rotate by the motor body, and the transmission fan is driven to rotate by the rotating side connecting rod. The transmission fan rotates along one side of the outer protection box to generate wind force. At this time, the wind force will enter the outer protection box along the side connecting frame on one side of the outer protection box, and blow out through the side connecting frame on the other side of the outer protection box. At the same time, the rotating side connecting rod will drive the side transmission plate to rotate, and the side cleaning brush is driven to rotate by the rotating side transmission plate, and the rotating side cleaning brush will move along the outer side of the filter screen;

[0019] S3, after the insulator body is lowered to the top of the top cleaning brush by the main electric push rod, the main electric push rod stops working and keeps the vertical position of the main electric push rod. When the motor body drives the transmission fan to rotate, it will synchronously drive the top fixed rod to rotate, and the rotating top fixed rod will drive the No. 3 bevel gear plate to rotate, and the rotating No. 3 bevel gear plate will synchronously drive the meshing No. 4 bevel gear plate to rotate, and the rotating No. 4 bevel gear plate will drive the bottom sliding ring to rotate;

[0020] S4. After pre-cleaning the surface of the insulator body, the height of the insulator body is raised and the insulator body is moved to the inside of the side connection box. At this time, the detection probe is driven to move horizontally after the top electric push rod is started. The two detection probes are driven to move to the surface of the insulator body by the two top electric push rods respectively. The detection probe starts to detect the charge on the surface of the insulator body, and the detection data is transmitted to the side detector through the signal transmission cable. At the same time, when the top fixed rod rotates, it will synchronously drive the top transmission gear disc to rotate, and the rotating top transmission gear disc will drive the side transmission teeth to move, and the movement of the side transmission teeth will synchronously drive the bottom transmission gear disc to rotate. The rotating bottom transmission gear plate will synchronously drive the bottom transmission rod to rotate, and the rotating bottom transmission gear plate will drive the bottom limit rod to rotate. The rotating bottom limit rod is movably connected to the inner side of the outer protection box through the No. 1 bearing plate, and the rotating bottom limit rod is stably supported by the No. 1 bearing plate, thereby improving the stability of the rotation of the bottom limit rod. The rotating bottom transmission rod will synchronously drive the No. 1 bevel gear plate to rotate, and the rotating No. 1 bevel gear plate will drive the meshing No. 2 bevel gear plate to rotate. Through the connection of the bottom connecting rod, the rotating No. 2 bevel gear plate will drive the main electric push rod to rotate, and the rotating main electric push rod will drive the top fixing ring and the insulator body to rotate.

[0021] Compared with the prior art, the present invention has the following beneficial effects:

[0022] 1) In the operation of the device and method for measuring the surface charge of high-voltage power transmission and transformation insulators, the insulator body is fixed on the surface of the top fixing ring. After the fixing is completed, the top fixing ring is driven to descend by the main electric push rod. After the top fixing ring descends, it will drive the insulator body along the top connecting port into the outer protection box, and after the detection is completed, the insulator body is pushed out by the main electric push rod. Through detection in the outer protection box and automatic lifting, the safety of the detection process is improved;

[0023] 2) During the operation of the device and method for measuring and detecting the surface charge of high-voltage power transmission and transformation insulators, when the external air is blown into the outer protection box by the rotating transmission fan, the dust particles in the air are blocked by the filter to reduce the entry into the outer protection box. The transmission fan improves the air circulation in the outer protection box, reduces moisture accumulation, and reduces the impact of dust particles on the insulator body, thereby improving the detection effect and accuracy. At the same time, the rotating side connecting rod drives the side transmission plate to rotate, and drives the side cleaning brush to rotate through the rotating side transmission plate. The rotating side cleaning brush moves along the outer side of the filter, and the dust on the surface of the filter is scrubbed by the side cleaning brush, thereby improving the air circulation in the outer protection box.

[0024] 3) During the operation of the device and method for measuring and detecting the surface charge of high-voltage power transmission and transformation insulators, after the insulator body is lowered to the top of the top cleaning brush by the main electric push rod, the main electric push rod stops working and maintains its vertical position. When the motor body drives the transmission fan to rotate, the top cleaning brush is synchronously driven to rotate. The rotating top cleaning brush scrubs and cleans the surface of the insulator body, pre-cleansing the surface of the insulator body, thereby improving the accuracy of subsequent surface charge detection of the insulator body;

[0025] 4) During the operation of the device and method for measuring the surface charge of high-voltage power transmission and transformation insulators, after the two top electric push rods drive the two detection probes to move to the surface of the insulator body respectively, the surface of the insulator body is charged by the detection probes, and the detection data is transmitted to the side detector through the signal transmission cable. At the same time, the rotating main electric push rod will drive the top fixing ring and the insulator body to rotate, and the rotating insulator body will rotate on one side of the two detection probes, and cooperate with the lifting and lowering of the main electric push rod, and the detection probes will be used to detect the charge of the entire surface of the insulator body. There is no need for the operator to repeatedly move the position of the detection probe, thereby improving the accuracy of the detection. BRIEF DESCRIPTION OF THE DRAWINGS

[0056] Example 2

[0057] This embodiment 2 provides a method for using a high-voltage power transmission and transformation insulator surface charge measurement and detection device, which is used to further illustrate the working process or principle of the high-voltage power transmission and transformation insulator surface charge measurement and detection device provided in the above embodiment 1, and the details are as follows:

[0058] A method for using a surface charge measurement and detection device for a high-voltage power transmission and transformation insulator comprises the following steps:

[0059] S1. First, start the main electric push rod 501, and drive the top fixing ring 503 to move vertically through the connection of the side support frame 502. After driving the top fixing ring 503 to move to the highest position, the operator places the insulator body 4 to be tested on the surface of the top fixing ring 503, and fixes the insulator body 4 by passing the bolts through the threaded holes 504, and fixes the insulator body 4 on the surface of the top fixing ring 503. After the fixation is completed, the top fixing ring 503 is driven to descend by the main electric push rod 501. After the top fixing ring 503 descends, it will drive the insulator body 4 to enter the outer protection box 1 along the top connecting port 2, and after the detection is completed, the insulator body 4 is pushed out by the main electric push rod 501. By detecting in the outer protection box 1 and automatically lifting and lowering, the safety of the detection process is improved;

[0060] S2. When the main electric push rod 501 drives the insulator body 4 to descend, the motor body 601 is started at this time, and the motor body 601 is started, and the side connecting rod 603 is driven to rotate by the motor body 601, and the transmission fan 607 is driven to rotate by the rotating side connecting rod 603. The transmission fan 607 rotates along one side of the outer protection box 1 to generate wind force. At this time, the wind force will enter the outer protection box 1 along the side connecting frame 3 on one side of the outer protection box 1, and blow out through the side connecting frame 3 on the other side of the outer protection box 1. When the rotating transmission fan 607 blows the external air into the outer protection box 1, it is blocked by the filter 606. Reduce the dust particles in the air from entering the outer protection box 1, improve the air circulation in the outer protection box 1 through the transmission fan 607, reduce moisture accumulation, and reduce the impact of dust particles on the insulator body 4, improve the detection effect and accuracy, and at the same time, the rotating side connecting rod 603 will drive the side transmission plate 604 to rotate, and drive the side cleaning brush 605 to rotate through the rotating side transmission plate 604, and the rotating side cleaning brush 605 will move along the outer side of the filter 606, and use the side cleaning brush 605 to brush the dust on the surface of the filter 606, thereby improving the air circulation in the outer protection box 1;

[0061] S3. After the insulator body 4 is lowered to the top of the top cleaning brush 8010 by the main electric push rod 501, the main electric push rod 501 stops working and maintains the vertical position of the main electric push rod 501. When the motor body 601 drives the transmission fan 607 to rotate, it will synchronously drive the top fixed rod 801 to rotate. The rotating top fixed rod 801 will drive the No. 3 bevel gear plate 802 to rotate. The rotating No. 3 bevel gear plate 802 will synchronously drive the meshing No. 4 bevel gear plate 805 to rotate. The rotating No. 4 bevel gear plate 805 will drive the bottom sliding ring 806 to rotate. The bottom sliding ring 806 slides along the surface of the bottom sliding rail 807, and the rotating No. 4 bevel gear plate 805 can be supported by the bottom sliding rail 807, and the outer The connection of the connecting rod 808 firmly supports the No. 4 bevel gear disc 805 on the inner side of the outer protection box 1, and at the same time, the rotating No. 3 bevel gear disc 802 is movably connected to one side of the side inner fixing frame 803 through the No. 3 bearing disc 804, and the rotating No. 3 bevel gear disc 802 is supported by the side inner fixing frame 803, thereby improving the rotation stability of the No. 3 bevel gear disc 802, and the rotating No. 4 bevel gear disc 805 drives the top support rod 809 to rotate, and the rotating top support rod 809 drives the top cleaning brush 8010 to rotate, and the rotating top cleaning brush 8010 scrubs and cleans the surface of the insulator body 4, and pre-cleans the surface of the insulator body 4, thereby improving the accuracy of subsequent surface charge detection of the insulator body 4;

[0062] S4, after pre-cleaning the surface of the insulator body 4, the height of the insulator body 4 is raised, and the insulator body 4 is moved to the inner side of the side connection box 901.
