"exemplary" means "serving as an example, instance, or illustration" herein, and any illustration, embodiment, or steps described as "exemplary" herein should not be construed as a preferred or advantageous alternative.
In this document, "first", "second", etc. do not mean their importance or order, etc., but merely mean that they are distinguished from each other so as to facilitate the description of the document.
For the sake of simplicity, the drawings only schematically show the parts relevant to the present invention, and they do not represent the actual structure as a product.
Fig. 1 is a schematic cross-sectional view of an exemplary embodiment of a surge arrester with a fixed series gap. As shown in fig. 1, the arrester with a fixed series gap includes a first conductive block 10, a first electrode 21, an insulating member 31, a second conductive block 32, a second electrode 22, a nonlinear resistor 33, an end conductor 40, twelve supporting rods 50 (only two of which are visible in fig. 1), and an insulating sheath 60. The first conductive block 10 is used for electrically connecting with a high-voltage lead; the end conductor 40 is used for electrical connection with the supporting cross-arm of the electrical tower.
Fig. 2 is a schematic view of a partial structure of the arrester with fixed series gap shown in fig. 1, in which the insulating sheath 60 is not shown. Fig. 3 is a schematic view of a partial structure of the surge arrester with a fixed series gap shown in fig. 1, in which a first conductive block 10, an end conductor 40, and a support rod 50 are shown. FIG. 4 is a cross-sectional view taken along line IV-IV of FIG. 1.
As shown in fig. 1 and 2, the first conductive piece 10, the insulator 31, the second conductive piece 32, the nonlinear resistor body 33, and the end conductor 40 are stacked in this order in one assembling direction a. The insulator 31, the second conductive piece 32, and the nonlinear resistor body 33 are, for example, cylindrical bodies coaxially arranged. The insulating member 31 is used to isolate the first conductive block 10 from the second conductive block 32, so that the first conductive block 10 and the second conductive block 32 cannot be contacted to conduct electricity during normal use. The second conductive bumps 32 can be in contact with the nonlinear resistor body 33 and can conduct electricity between the nonlinear resistor body 33 and the end conductors 40. The first electrode 21 is connected to the first conductive block 10. The second electrode 22 is connected to the second conductive bump 32. A series gap is formed between the first electrode 21 and the second electrode 22. The nonlinear resistor body 33 includes, for example, a plurality of zinc oxide varistor sheets 331 stacked in the mounting direction a.
As shown in fig. 1 to 3, each support bar 50 extends in the fitting direction a. One end of the support bar 50 is connected to the first conductive block 10, and the other end is connected to the end conductor 40. As shown in fig. 2 and 4, twelve support rods 50 are uniformly arranged around the insulator 31, the second conductive piece 32, and the nonlinear resistor body 33 in a circumferential direction perpendicular to the fitting direction a. The support rod 50 is made of an insulating material, such as glass fiber and epoxy resin, and has a certain strength. In other exemplary embodiments, the number of support rods 50 may be adjusted as desired, such as four, eight, or ten.
Specifically, as shown in fig. 1, in the present exemplary embodiment, the first conductive block 10 has a plurality of first positioning grooves 11 extending in the mounting direction a. The end conductor 40 has several second positioning slots 41 extending in the assembly direction a. One end of each support rod 50 is inserted into one first positioning groove 11, and the other end is inserted into one second positioning groove 41. The groove wall of the first positioning groove 11 and the groove wall of the second positioning groove 41 are in interference fit with the supporting rod 50 to prevent the supporting rod 50 from moving relative to the first conducting block 10 and the end conductor 40, thereby facilitating to keep the relative positions of the first conducting block 10, the insulating member 31, the second conducting block 32, the nonlinear resistor 33 and the end conductor 40 along the assembling direction a unchanged to ensure the electrical performance of the lightning arrester. In the assembling process of the lightning arrester, the supporting rod 50 is, for example, inserted into the first positioning groove 11 and the second positioning groove 41, and then forms an interference fit with the groove wall of the first positioning groove 11 and the groove wall of the second positioning groove 41 by means of crimping.
As shown in fig. 1, the insulating sheath 60 is wrapped around the circumferential outer sides of the first conductive block 10, the insulator 31, the second conductive block 32, the nonlinear resistor 33, and the end conductor 40, where the circumferential direction is a circumferential direction perpendicular to the assembling direction a. The support rod 50 is embedded in an insulating sheath 60. The insulating sheath 60 is made of, for example, silicone rubber. The insulating sheath 60 is integrally formed, for example, after the other components are assembled in the arrester manufacturing process, but is not limited thereto. In the exemplary embodiment, the surface of the insulating sheath 60 is provided convexly with a plurality of sheds 61 arranged in the assembly direction a. The shed 61 is annular extending in a circumferential direction perpendicular to the fitting direction a. The arrangement of the umbrella skirt can increase the creepage distance of the lightning arrester.
Under the action of lightning overvoltage, the series gap is instantaneously broken down, the lightning arrester presents low impedance, and lightning current is discharged to the ground; after lightning surge, the power frequency voltage loads the lightning arrester, the resistance of the lightning arrester is instantly increased, the insulation of the series gap is recovered, and the electric arc is naturally extinguished in a short time.
In the lightning arrester with the fixed series gap, the first conductive block 10, the end conductor 40, the support rod 50 and the insulating sheath 60 form a stable support structure, so that the lightning arrester has high structural strength.
As shown in fig. 1, in the exemplary embodiment, the first electrode 21 is superimposed on a side of the first conductive piece 10 facing away from the insulating member 31 in the fitting direction a. The arrester with fixed series gap further comprises a first conductive bolt 71 and a first fastening nut 72. The first conductive bolt 71 is inserted through the first electrode 21 and the first conductive block 10 in the fitting direction a. The first conductive bolt 71 is used for connecting a high-voltage wire when in use. The nut of the first conductive bolt 71 is located on the opposite side of the first conductive block 10 from the first electrode 21 in the fitting direction a. The first fastening nut 72 is screwed to the first conductive bolt 71 and can clamp the first conductive block 10 and the first electrode 21 with the nut of the first conductive bolt 71. This structure can facilitate the assembly of the arrester.
As shown in fig. 1, in the exemplary embodiment, the first conductive piece 10 has a first fitting recess 12 at an end facing away from the first electrode 21 in the fitting direction a. The nut of the first conductive bolt 71 is seated in the first fitting groove 12. The groove wall of the first fitting groove 12 can abut against the nut of the first conductive bolt 71 to prevent the first conductive bolt 71 from rotating relative to the first conductive block 10. Whereby the assembly of the arrester can be facilitated.
As shown in fig. 1, in the exemplary embodiment, the surge arrester with fixed series gap further includes a first pad 81 that is electrically conductive. The first spacer 81 is fitted in the first fitting groove 12 and is disposed between the first conductive block 10 and the insulating member 31 in the fitting direction a. Thereby contributing to the improvement of the structural strength.
As shown in fig. 1, in the exemplary embodiment, the first conductive piece 10 has a first plug-in connection 13 at one end in the mounting direction a close to the first electrode 21. The side wall of the first electrode 21 facing the first conductive block 10 in the mounting direction a has a second plug-in structure 211. The first and second insertion structures 13 and 211 are insertion-fitted in the fitting direction a to restrict relative movement of the first conductive block 10 and the first electrode 21 in a direction perpendicular to the fitting direction a. Specifically, in the present exemplary embodiment, the first plug structure 13 is provided as a socket, and the second plug structure 211 is provided as a plug matching the shape of the socket. But not limited thereto, in other exemplary embodiments, the second plug structure 211 may be provided as a socket, and the first plug structure 13 may be provided as a plug matching the shape of the socket. The first insertion structure and the second insertion structure are arranged to limit relative movement of the first conductive block and the first electrode along a direction perpendicular to the assembling direction, so that the extending angle and direction of the first electrode relative to the first conductive block are fixed.
As shown in fig. 1, in the exemplary embodiment, the arrester with fixed series gap further includes a second conductive bolt 73, a second fastening nut 74, and a second spacer block 82 that is electrically conductive. The second conductive bolt 73 is inserted through the end conductor 40 in the fitting direction a. The second conductive bolt 73 is used to connect the support cross arm of the electrical tower when in use. One end of the second conductive bolt 73 in the fitting direction a near the nonlinear resistor body 33 has a nut. The second fastening nut 74 is screwed to the second conductive bolt 73 and can clamp the end conductor 40 with the nut of the second conductive bolt 73. The end conductor 40 has a second fitting recess 42 at one end in the fitting direction a close to the nonlinear resistor body 33. The nut of the second conductive bolt 73 is seated in the second fitting groove 42. The groove wall of the second fitting groove 42 can abut against the nut of the second conductive bolt 73 to prevent the second conductive bolt 73 from rotating relative to the end conductor 40, whereby the fitting of the arrester can be facilitated. The second spacer 82 is embedded in the second fitting groove 42 and disposed between the nonlinear resistor body 33 and the end conductor 40 in the fitting direction a, which contributes to an improvement in structural strength.
