Description

Technical Field

[0001] This invention relates to the field of surge arrester resistor sheets, and more specifically, to a water-based glass glaze spraying device and spraying method. Background Technology

[0002] Metal oxide surge arresters utilize zinc oxide varistors with excellent nonlinear voltage-current characteristics, resulting in significantly improved protection characteristics under steep slope, lightning surge, and switching surge conditions compared to traditional silicon carbide surge arresters. In particular, zinc oxide varistors exhibit excellent steep slope response characteristics, with no delay in response to steep slope voltages, low residual switching voltage, and no discharge dispersion. This overcomes the inherent disadvantages of silicon carbide surge arresters, such as high steep slope discharge voltage due to discharge delay and high switching surge discharge voltage due to large discharge dispersion. This significantly increases the protection margin under steep slope and switching surge conditions. Furthermore, in terms of insulation coordination, the protection margins under steep slope, lightning surge, and switching surge conditions can be nearly identical, providing optimal protection for power equipment and improving protection reliability. Zinc oxide surge arresters also have the ability to absorb lightning overvoltage, switching overvoltage, and power frequency transient overvoltage.

[0003] Currently, when spraying resistors for surge arresters, the size of the resistors varies because surge arresters are of different sizes. This necessitates the ability to quickly and effectively adjust the size of the spraying equipment to handle resistors of different sizes. Furthermore, if dust adheres to the outer surface of the resistors during spraying, it will affect the quality of the glass glaze formation, thereby impacting the corrosion resistance of the resistors.

[0066] A spraying method using a water-based glass glaze spraying device includes the following steps:

[0067] First, add the main amount of glass glaze liquid into the glaze storage box 3 through the glaze adding tube 4;

[0068] Then the resistor sheet is placed between the clamping mechanism 6 and the driving mechanism 5, and the clamping mechanism 6 and the driving mechanism 5 are used to clamp the resistor sheet.

[0069] At this time, the distance between the spraying mechanism 9 and the resistor is adjusted according to the size of the resistor. The lifting mechanism 8 is slid by starting the transmission mechanism 7, which drives the spraying mechanism 9 to the specified position.

[0070] At this point, the drive mechanism 5, the spraying mechanism 9 and the hot air blowing mechanism 10 can be started. The drive mechanism 5 drives the lifting mechanism 8 through the transmission mechanism 7 to work, so that the spraying mechanism 9 moves up and down in a cycle.

[0071] During the cyclic up-and-down movement of the spraying mechanism 9, the outer surface of the resistor sheet without glass glaze is cleaned by the hot air blowing mechanism 10, and the outer surface of the resistor sheet with glass glaze is dried by hot air.

[0072] Once the resistive sheet coating is complete, the drive mechanism 5, coating mechanism 9, and hot air mechanism 10 can be turned off, and the resistive sheet can be removed by pulling the clamping mechanism 6.

[0073] The working principle of the water-based glass glaze spraying equipment and spraying method:

[0074] In use, first add the main amount of glass glaze liquid into the glaze storage box 3 through the glaze tube 4, then pull the slide plate 62 upward to place the center of the resistor between the turntable 63 and the rotating shaft 53, and then release the slide plate 62 so that the slide plate 62 clamps the resistor through the turntable 63 under the action of the clamping spring 65.

[0075] Then the electric slide table 74 can be started to make the slider 73 slide towards or relative to each other, which will drive the adjusting wheel 72 to slide towards or relative to each other. At this time, the belt 71 will pull the adjustment wheel 75 and the driving wheel 54 to adjust the distance between them, which will then drive the sliding block 83 to slide and compress the return spring 84 until the nozzle 94 reaches the specified distance of the resistor.

[0076] At this time, the drive motor 52, pump body 91, air extraction motor 104 and electric heating grid 106 can be started. The rotation of the drive motor 52 will drive the rotating shaft 53 to rotate, which in turn drives the resistor and the drive wheel 54 to rotate. The drive wheel 54 will drive the driven wheel 75 to rotate through the belt 71, which in turn drives the reciprocating screw 81 to rotate, so that the spray box 93 slides up and down along the inner side wall of the fixed frame 82, and the spray head 94 and the air blowing head 95 slide up and down in a cycle.

[0077] The operation of pump 91 draws the glass glaze from the glaze storage tank 3 into the glaze delivery pipe 92, then pumps it into the spray box 93, and finally sprays the atomized glass glaze from the nozzle 94 onto the outer surface of the resistor element. The operation of the suction motor 104 drives the fan blades 105, causing outside air to be filtered by the filter screen 102, heated by the electric heating grid 106, and then enter the air distribution ring 108 through the air delivery pipe 107. The hot air entering the air distribution ring 108 will add to the glaze delivery pipe 92, thereby adding to the glass glaze inside the glaze delivery pipe 92, ensuring the temperature of the glass glaze sprayed from the nozzle 94, preventing the temperature from being too low to form an atomization effect. The gas in the air distribution ring 108 will then enter the blowing head 95 through the spray box 93, and be blown out by the air... Air nozzle 95 blows onto the outer surface of the resistor sheet. At this time, one air nozzle 95 will effectively heat and clean the parts of the resistor sheet that are not coated with glass glaze, so that the outer surface of the resistor sheet has a certain temperature, which is more conducive to the adhesion of glass glaze. The other air nozzle 95 will dry the outer surface of the resistor sheet coated with glass glaze to a certain extent, preventing the glass glaze on the outer surface of the resistor sheet from forming water droplets, resulting in uneven thickness and affecting the anti-corrosion effect of the resistor sheet after spraying. After spraying, the drive motor 52, pump body 91, air extraction motor 104 and electric heating grid 106 can be turned off. The resistor sheet can be removed by pulling up the slide plate 62. The above operation can be repeated to perform glass glaze spraying on new resistor sheets.

[0078] It should be noted that the specific models and specifications of the drive motor 52, pump body 91, air extraction motor 104, and electric heating network 106 need to be selected and determined according to the actual specifications of the device. The specific selection calculation method adopts the existing technology in this field, so it will not be described in detail.

[0079] The above description is merely a preferred embodiment of the present invention and is not intended to limit the invention. Various modifications and variations can be made to the invention by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the invention should be included within the scope of protection of the invention.
