Description
TECHNICAL FIELD

[0002] The stubborn stains on the surface of the insulator not only affect the appearance of the equipment, but also directly threaten the safe and stable operation of the power system, and its harm runs through the whole chain from the decline of the insulation performance, equipment damage to system failure, among which the stains such as dust, oil stains and salt mist have hygroscopicity, and in rainy days or high humidity environment, the conductive water film will be formed, so that the surface resistance of the insulator is greatly reduced. When the stains contain soluble salt (such as sodium chloride in salt mist) or acidic substances, the water film will become a conductive channel, resulting in surface flashover (current along the surface rather than air breakdown) on the surface of the insulator. When the flashover occurs, high-temperature arc will be generated, which may burn the insulator body, and even cause line trip and power failure, so that monitoring equipment needs to be arranged on the insulator to monitor the stubborn stains on the insulator, and generally, visual monitoring is adopted, that is, the camera shooting monitoring mode is adopted, when the amount of the stubborn stains on the insulator is large, the staff needs to clean or replace the insulator manually, but the following defects still exist.

[0026] Working principle: In use, the lightning insulation sub 4 is used for normal lightning protection work, and the size, material and the like of the simulation insulation sub 5 are the same as those of the lightning insulation sub 4, so that the stubborn dirt and surface dust accumulated on the lightning insulation sub 4 and the simulation insulation sub 5 are roughly the same in the same environment. Since the lightning insulation sub 4 is fixedly installed for lightning protection work, it is not convenient to directly detect the dirt on the lightning insulation sub 4, so the weight sensor 6 is arranged at the bottom end of the simulation insulation sub 5 to detect the weight of the simulation insulation sub 5, thereby indirectly monitoring the stubborn dirt accumulated on the lightning insulation sub 4. In the monitoring process, first, start two rotating motors 805, drive two guide rails 802 to move close to each other through the rotation of the screw rod 804, until the guide rail 802 moves to the corresponding two installation boxes 7031 between the two tooth ring seats 702, complete the butt joint, in the original state, the limiting plate 7036 enters the inside of the opening 7032, so that the circumferential plate of the installation box 7031 and the limiting plate 7036 form a limit, and the bottom block 7042 at the bottom of the bottom support 7041 is limited and fixed, and after the guide rail 802 moves between the two installation boxes 7031, the pressure plate 7039 is pressed by the pressure rod 807 to push the limiting plate 7036 into the inside of the side box 7035; Then the electromagnet 7034 on the installation box 7031 corresponding to the lightning rod insulator 4 is energized to generate a repulsive force on the magnetic block 7044, and the electromagnet 7034 on the installation box 7031 corresponding to the simulation insulator 5 is energized to generate an attractive force on the magnetic block 7044, so that the two bottom blocks 7042 enter the two installation boxes 7031 corresponding to the simulation insulator 5 under the action of the magnetic force along the guide rail 802 respectively, and then control the guide rail 802 to move back, so that the limiting plate 7036 moves outward to position and fix the bottom block 7042; Then drive the sleeve 70410 to move upward through the electric telescopic rod 70412, so that the sleeve 70410 is sleeved outside the bottom pipe 906, and the push rod 70411 is inserted into the inside of the bottom pipe 906, the movable baffle 909 is pushed to move upward, so that the movable baffle 909 is separated from the bottom baffle ring 907, and the clamping rod 914 is pushed to separate from the clamping slot 905 through the longitudinal rod 915 and the connecting rod 916. At this time, the water pump is started, which can drive the plasma water tank to enter the inside of the bottom pipe 906 through the annular outer pipe 901 and the annular inner pipe 904, and enter the longitudinal pipeline 7045 from the second water pipe 910 and the first water hole 908, and then spray outward from the nozzle 7047 on the horizontal branch pipe 7046 to the umbrella skirt surface to wash the stains on the umbrella skirt surface; When cleaning, start the driving motor 707 to drive the gear 706 to rotate, and the gear 706 is engaged with the tooth ring seat 702 on both sides, so as to drive the tooth ring seat 702 to rotate, so that the two surface cleaning pieces 704 can rotate around the simulation insulator 5. When the water pump is started, the umbrella skirt surface is washed to remove the dust on the surface. After cleaning, the water pump is turned off, and the hot air blower 7048 is started, so that the longitudinal pipeline 7045 provided with the hot air blower 7048 rotates, and hot air is blown from the nozzle 7047 to the umbrella skirt surface to dry the plasma water on the umbrella skirt surface, so as to ensure the accuracy of the weighing result of the simulation insulator 5. Then the weight sensor 6 is used to detect the weight of the simulation insulator 5 to obtain the result Ma, and the weights of the simulation insulator 5 and the lightning rod insulator 4 are both Mb, so that the weight of the stubborn dirt M=Ma-Mb can be obtained, so as to monitor the stubborn dirt on the lightning rod insulator 4; In the cleaning process, the control tooth ring seat 702 rotates the number of whole circle, after cleaning, the tooth ring seat 702 is rotated back to the original state, and then the electric telescopic rod 70412 pulls the sleeve 70410 to move downward and separate from the bottom pipe 906, when separating, the movable baffle 909 moves back to close the bottom of the bottom pipe 906, and drives the clamping rod 914 to move back and clamp into the clamping groove 905, the annular inner tube 904 is clamped and fixed, which is convenient for subsequent use; Then control the guide rail 802 to move between the corresponding two installation boxes 7031, and make the electromagnet 7034 on the two installation boxes 7031 pass through the reverse current, so that the bottom block 7042 moves back, and then repeat the above operation, which can clean the dust on the surface of the umbrella skirt of the lightning insulator 4 by plasma water flushing and drying.
