[0032] The following is combined Figures 1 to 6 This invention describes the surge arrester core processing device provided by this utility model.
[0033] Before describing the surge arrester core processing device provided by this utility model, the surge arrester core 60 will first be described as an example. See [link to description]. Figure 6 As shown, in this example, the surge arrester core 60 includes an upper electrode 610, a gasket 620, a resistor 630, a heat shrink tubing 640, a sleeve 650, and a lower electrode 660. The upper electrode 610, gasket 620, resistor 630, sleeve 650, and lower electrode 660 are pressed together to form the inner core. The heat shrink tubing 640 is fitted onto the inner core and heat-shrinked to form the surge arrester core 60.
[0034] It should be noted that the surge arrester core processing device provided by this utility model is not limited to processing... Figure 6 The surge arrester core 60 shown can also be used for processing with... Figure 6 This utility model does not limit the core components with similar structures to those in medium surge arresters.
[0035] The following is combined Figures 1 to 5 This invention describes the surge arrester core processing device provided by this utility model.
[0036] See Figures 1 to 4 As shown, the surge arrester core processing device provided in this embodiment includes: a workbench 10, a core fixing assembly 20 and a core pressing assembly 30. The core fixing assembly 20 and the core pressing assembly 30 are both disposed on the workbench 10. The core fixing assembly 20 is used to fix the core column assembly (including upper electrode 610, gasket 620, resistor sheet 630, pad 650, lower electrode 660, etc.).
[0037] The core clamping assembly 30 includes a first clamping unit 310 and a second clamping unit 320. The core fixing assembly 20 is located between the first clamping unit 310 and the second clamping unit 320. The first clamping unit 310 includes a first linear drive member 311 and a first push member 312. The output end of the first linear drive member 311 is connected to the first push member 312. The second clamping unit 320 includes a second linear drive member 321 and a second push member 322. The output end of the second linear drive member 321 is connected to the second push member 322 so as to clamp the core column assembly through the first push member 312 and the second push member 322.
[0038] The surge arrester core processing device provided by this utility model, by setting a core fixing component 20 and a core pressing component 30 on the workbench 10, allows the core column components used to form the surge arrester core 60 to be placed on the core fixing component 20 during processing. The core pressing component 30 then presses the components together to form the surge arrester core 60. A heat shrink tubing 640 is then fitted onto the surge arrester core 60, and finally, a hot air gun is used to evenly heat the heat shrink tubing 640, causing it to shrink uniformly. This process is highly efficient and requires only one person to operate, solving the problem that existing heat shrink core processes typically require two or more people to work together, resulting in high labor intensity and low efficiency.
[0039] Specifically, see Figure 1 and Figure 2 As shown, the top of the workbench 10 is provided with a work surface, which provides installation space for the core fixing assembly 20, the core clamping assembly 30, and other related components. The length, width, and height of the work surface can be set according to actual needs, and this utility model does not impose specific limitations on them.
[0040] The core fixing assembly 20 is used to fix the core, ensuring that the core can maintain its position when it is pressed and fitted with the heat shrink tubing 640.
[0041] The core pressing assembly 30 is used to apply pressure from both ends to the core column assembly (including upper electrode 610, gasket 620, resistor sheet 630, pad 650, lower electrode 660, etc.) placed on the core fixing assembly 20, so that each component forms a core column under pressure, which facilitates the subsequent installation of heat shrink tubing 640 and heat shrinking treatment.
[0042] The core clamping assembly 30 includes a first clamping unit 310 and a second clamping unit 320. The first clamping unit 310 includes a first linear drive 311 and a first pusher 312, with the output end of the first linear drive 311 connected to the first pusher 312. The second clamping unit 320 includes a second linear drive 321 and a second pusher 322, with the output end of the second linear drive 321 connected to the second pusher 322. During clamping, the first linear drive 311 drives the first pusher 312 to move, while the second linear drive 321 drives the second pusher 322 to move, thus clamping the components such as the upper electrode 610, pad 620, resistor sheet 630, pad cylinder 650, and lower electrode 660 located between the first clamping unit 310 and the second clamping unit 320 into a core column.
[0043] The first linear drive 311 and the second linear drive 321 can be pneumatic, hydraulic, or electric actuators known in the prior art. Preferably, in this embodiment, both the first linear drive 311 and the second linear drive 321 are pneumatic actuators. Pneumatic actuators have advantages such as fast response speed, light weight, simple control system, high reliability, strong environmental adaptability, and low maintenance cost. Compared with electric or hydraulic actuators, pneumatic actuators can work stably in harsher environments and are easy to operate and durable.
[0044] See Figures 1 to 4 As shown, according to some embodiments of the present invention, the first pressing unit 310 further includes a first drive motor 313, which is disposed on the first pusher 312; the second pressing unit 320 further includes a second drive motor 323, which is disposed on the second pusher 322; the output shaft of the first drive motor 313 is used to connect to one end of the core, and the output shaft of the second drive motor 323 is used to connect to the other end of the core, so as to drive the core to rotate through the first drive motor 313 and the second drive motor 323.
[0045] By setting the first drive motor 313 and the second drive motor 323, after the heat shrink tubing 640 is fitted into the core, the first drive motor 313 and the second drive motor 323 can drive the core column to rotate. The operator can hold a hot air gun to bake the heat shrink tubing 640 evenly, so that the heat shrink tubing 640 can shrink evenly.
[0046] Specifically, the first drive motor 313 and the second drive motor 323 are synchronous speed-regulating motors, which can drive the core column to rotate synchronously and uniformly from both ends, and ensure that the core column is coaxial when rotating.
[0047] See Figure 1 , Figure 3 and Figure 4As shown, according to some embodiments of the present invention, the first drive motor 313 is provided with a fixing groove 314 for fixing the heat shrink tubing 640 on the side facing the core fixing assembly 20, and the fixing groove 314 is coaxially arranged with the output shaft of the first drive motor 313.
[0048] By providing a fixing groove 314 on the side of the first drive motor 313 facing the core fixing assembly 20, the heat shrink tubing 640 can be initially fixed using the fixing groove 314. After the first linear drive member 311 and the second linear drive member 321 press the core column, the heat shrink tubing 640 can be directly fitted onto the core column, thereby simplifying the processing operation.
[0049] It should be noted that the heat shrink tubing 640 is similar to a corrugated pipe. In its initial state, it can be compressed axially and one end of it can be fixed in the fixing groove 314. First, the heat shrink tubing 640 will not cause interference when the core column is pressed. Second, after the core column is pressed, the heat shrink tubing 640 can be unfolded axially and fitted outside the core column.
[0050] See Figure 3 As shown, according to some embodiments of the present invention, the core fixing assembly 20 includes a lower fixing plate 210, an upper fixing plate 220 and at least one support base 230. Both the lower fixing plate 210 and the upper fixing plate 220 are provided with semi-circular grooves for fixing the core. The lower fixing plate 210 is disposed on the support base 230, and the upper fixing plate 220 is disposed opposite to the lower fixing plate 210 and fastened together.
[0051] By setting the lower fixing plate 210 and the upper fixing plate 220, components such as the upper electrode 610, gasket 620, resistor sheet 630, pad 650, and lower electrode 660 can be placed in the cylindrical groove formed between the lower fixing plate 210 and the upper fixing plate 220, which facilitates positioning during clamping and prevents axial displacement. In addition, by setting the support base 230, the lower fixing plate 210 and the upper fixing plate 220 can be supported and fixed, so that the fixing plates and the upper fixing plate 220 can support the core column in the cylindrical groove at a set height.
[0052] See Figures 1 to 3 As shown, according to some embodiments of the present invention, the support base 230 is a lifting support base.
[0053] By setting the support base 230 as a lifting support base, the lower fixed plate 210 and the upper fixed plate 220 can be driven to move up and down using the lifting support base, thereby raising the core column in the cylindrical groove to a set height and improving the flexibility of the device.
[0054] See Figures 1 to 3 As shown, according to some embodiments of the present invention, the core fixing assembly 20 includes a plurality of support seats 230, which are spaced apart on the worktable 10 along a first direction.
[0055] It should be noted that, in this embodiment, "first direction" specifically refers to... Figure 3 The arrow in the image indicates the length direction of the worktable 10.
[0056] By setting multiple support seats 230, different parts of the lower fixing plate 210 and the upper fixing plate 220 can be supported, thereby improving the stability of the core column during fixing and preventing the lower fixing plate 210 and the upper fixing plate 220 from shaking.
[0057] As an example, in this embodiment, the core fixing assembly 20 includes two support seats 230, which are spaced apart in a first direction on the worktable 10.
[0058] See Figure 1 and Figure 2 As shown, according to some embodiments of the present invention, the first pressing unit 310 further includes a first mounting base 315, a first linear drive member 311 is disposed on the first mounting base 315, and a first push member 312 slides with the first mounting base 315 along a first direction.
[0059] By setting the first mounting base 315 and configuring the first pusher 312 and the first mounting base 315 in a sliding fit along the first direction, the smooth and precise movement of the first pusher 312 can be achieved, ensuring the stability and accuracy of the first pusher 312.
[0060] Specifically, in this embodiment, the top surface of the first mounting base 315 is provided with a sliding groove along the first direction, and the bottom of the first pusher 312 is provided with a sliding part that slides in cooperation with the sliding groove.
[0061] See Figure 1 and Figure 2 As shown, according to some embodiments of the present invention, the first mounting base 315 and the worktable 10 are slidably engaged in a first direction.
[0062] By configuring the first mounting base 315 and the worktable 10 in a sliding fit along the first direction, the position of the first mounting base 315 on the worktable 10 along the length direction can be adjusted, thereby adjusting the distance between the first pusher 312 and the second pusher 322, so that the surge arrester core processing device can be applied to the processing of surge arrester cores 60 of different lengths, thus improving the flexibility of the device.
[0063] Specifically, in this embodiment, the top surface of the workbench 10 is provided with a slide rail along the first direction, and the bottom of the first mounting base 315 slides in cooperation with the slide rail.
[0064] See Figure 1 and Figure 2As shown, according to some embodiments of the present invention, the second pusher 322 and the worktable 10 slide in a first direction.
[0065] By configuring the second pusher 322 and the worktable 10 in a sliding fit along the first direction, the second pusher 322 can move smoothly and accurately, ensuring the stability and accuracy of the second pusher 322.
[0066] The following describes the processing flow of the surge arrester core processing device provided by this utility model for manufacturing the surge arrester core 60. (See also...) Figure 5 As shown.
[0067] (1) Select a lower fixing plate 210 and an upper fixing plate 220 with the same diameter as the required resistor sheet 630. (The length of the lower fixing plate 210 and the upper fixing plate 220 is about 100mm longer than the total size of the preheating shrink core column, so as to facilitate extraction).
[0068] (2) Place the dried lower electrode 660, resistor 630, pad 650, pad 620 and upper electrode 610 horizontally in the semi-circular groove of the lower fixing plate 210.
[0069] (3) Turn on the first linear drive 311 and the second linear drive 321 to press the electrodes at both ends of the core column, and then put the pre-set heat shrink tube 640 into the lower fixing plate 210, the upper fixing plate 220 and the core column until the heat shrink tube 640 is put into the upper pressing spring.
[0070] (4) Slowly pull out the lower fixing plate 210 and the upper fixing plate 220 inside the heat shrink tubing 640, and keep the core column inside the heat shrink tubing 640.
[0071] (5) Start the first drive motor 313 and the second drive motor 323, and make the output shafts of the first drive motor 313 and the second drive motor 323 rotate synchronously, driving the core column to rotate at a constant speed, ensuring that the core column does not shift axially when it rotates.
[0072] (6) When the core column rotates, use a hot air gun to heat the heat shrink tube 640 back and forth in the first direction to make it shrink evenly and ensure that the shrunken heat shrink tube 640 is free of air bubbles.
[0073] (7) Take out the heat-shrinkable core column, cool it to room temperature, trim the excess heat-shrinkable tubes 640 at both ends, and conduct a partial discharge test in advance.
[0074] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
