Description

Technical Field

[0001] The utility model relates to the technical field of GIS lightning arresters, in particular to a core assembly positioning tool. Background Art

[0002] GIS (Gas Insulated Switchgear, GIS) arrester is an important electrical appliance in the power substation system. Its main function is to protect GIS combined electrical appliances from atmospheric overvoltage and operating overvoltage. GIS arrester is mainly composed of resistor core, base plate, tank, contact, basin insulator, low-voltage terminal, explosion-proof structure. According to the structural classification, it can be divided into single-phase single tank type and three-phase common tank type. The main difference is the number of internal resistor cores, which can be three-column structure or single-column structure. Regardless of the structure, the assembly of each column resistor core is through the stacking of multiple valve plates. When the core stacking height is about 1m, the horizontality of the upper surface of the core and the position of the entire column core are difficult to guarantee.

[0003] Usually after the tank body is connected, it is found that the position of the core body is deviated when installing the pot-type insulator. When the deviation is large, the core body and the top pot-type insulator will be misaligned, causing the internal rods to be stressed. If the rods are subjected to stress for a long time, their service life will be shortened.

[0004] In the prior art, when workers find that the core has a large position deviation when installing a pot-type insulator, they need to remove the pot-type insulator and the tank body and adjust the position of the core body. Repeated disassembly and assembly will reduce assembly efficiency and affect production progress and product quality.

[0005] Therefore, it is urgent to design a core assembly positioning tool to solve the above technical problems. Utility Model Content

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0033] In the present utility model, unless otherwise clearly specified and limited, a first feature being "above" or "below" a second feature may include that the first and second features are in direct contact, or may include that the first and second features are not in direct contact but are in contact through another feature between them. Moreover, a first feature being "above", "above" and "above" a second feature includes that the first feature is directly above and obliquely above the second feature, or simply indicates that the first feature is higher in level than the second feature. A first feature being "below", "below" and "below" a second feature includes that the first feature is directly below and obliquely below the second feature, or simply indicates that the first feature is lower in level than the second feature.

[0034] In the description of this embodiment, the terms "upper", "lower", "left", "right" and other directions or positional relationships are based on the directions or positional relationships shown in the drawings, and are only for the convenience of description and simplified operation, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation of the present invention. In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0035] In the description of this embodiment, unless otherwise specified, the term "plurality" refers to a quantity of two or more than two.

[0036] This embodiment provides a core assembly positioning tool, which can improve the accuracy of core assembly, and improve assembly efficiency and production progress.

[0037] like Figure 1-Figure 6 As shown, the core assembly and positioning tool mainly includes an upper fixing plate 100, a support member 200 and a lower fixing plate 300, the upper fixing plate 100 and the support member 200 are detachably connected, and the lower fixing plate 300 and the support member 200 are fixedly connected, that is, the lower fixing plate 300 and the support member 200 can be integrally formed or welded, and the upper fixing plate 100 is located directly above the lower fixing plate 300, and the upper fixing plate 100, the support member 200 and the lower fixing plate 300 define an installation space 400 for installing the core 20. The lower fixing plate 300 is provided with a plurality of through holes 310 for connecting the bottom plate 10 of the GIS arrester.

[0038] Based on the above design, before actually assembling the core 20 of the GIS lightning arrester, the operator can use bolts and pass the bolts through the through holes 310 of the lower fixing plate 300 and threadedly connect them with the base plate 10 of the GIS lightning arrester, thereby achieving a detachable connection between the lower fixing plate 300 and the base plate 10 of the GIS lightning arrester, which is convenient for subsequent disassembly work.

[0039] In addition, the upper fixing plate 100 in this embodiment is provided with a first through hole 110, and the lower fixing plate 300 is provided with a second through hole 330, and the first through hole 110 is coaxially arranged with the second through hole 330. The operator passes the core 20 of the GIS arrester through the first through hole 110 and the second through hole 330 in sequence and stacks it on the bottom plate 10 of the GIS arrester. When the cover plate 30 of the core 20 of the GIS arrester is flush with the end surface of the upper fixing plate 100, it can be determined that the levelness of the core 20 of the GIS arrester meets the requirements, avoiding the operating steps of repeatedly measuring the levelness of the core 20 of the GIS arrester, saving time and labor, and improving assembly efficiency and accuracy.

[0040] Optionally, the upper fixing plate 100 and the support member 200 in this embodiment are detachably connected, so as to facilitate the early assembly and later disassembly of the upper fixing plate 100 and the support member 200, and also facilitate the assembly of other components of the GIS arrester, such as the assembly of the valve plate. After the core 20 of the GIS arrester is positioned and assembled, if the operator needs to remove the core assembly positioning tool, the operator can directly remove the upper fixing plate 100 and release the bolts connecting the lower fixing plate 300 and the bottom plate 10, which is convenient and easy to operate.

[0041] The setting of the support member 200 in this embodiment can provide a reference for the core 20 of the GIS arrester, that is, the operator can confirm whether the center of the core 20 of the GIS arrester corresponds to the center line of the high-voltage terminal of the basin insulator by measuring the distance between the support member 200 and the core 20 of the GIS arrester, thereby ensuring that the position of the core 20 of the GIS arrester meets the requirements. The phenomenon of discovering the lateral deviation of the core 20 of the GIS arrester after the assembly is completed is avoided, the rework time is reduced or avoided, the assembly efficiency and accuracy are improved, and the production progress is improved.

[0042] Optionally, in this embodiment, the through hole 310 of the lower fixing plate 300 can be set to be multiple, so as to improve the stability of the connection between the lower fixing plate 300 and the base plate 10 of the GIS lightning arrester, avoid shaking and instability, and improve the assembly accuracy.

[0043] Optionally, the lower fixing plate 300 in this embodiment is provided with a plurality of weight-reducing holes 320. The provision of the weight-reducing holes 320 can reduce the weight of the core assembly and positioning tooling as much as possible, and facilitate the use and transportation of the core assembly and positioning tooling. This embodiment does not specifically limit the number, shape and position of the weight-reducing holes 320.

[0044] The support member 200 and the lower fixing plate 300 in this embodiment are arranged at a right angle to ensure the verticality of the support member 200, thereby improving the verticality of the core 20 of the GIS arrester and improving the assembly accuracy.

[0045] Furthermore, if Figure 1-Figure 3 As shown, in this embodiment, a reinforcing rib 500 is provided between the lower fixing plate 300 and the support member 200, one side of the reinforcing rib 500 is connected to the lower fixing plate 300, and the other side of the reinforcing rib 500 is connected to the support member 200. The provision of the reinforcing rib 500 can improve the stability and reliability of the connection between the support member 200 and the lower fixing plate 300, and extend the service life; at the same time, it can ensure the verticality of the support member 200 as much as possible, and improve the assembly accuracy of the core 20 of the GIS arrester.

[0046] Optionally, the reinforcing rib 500 in this embodiment can be welded to the support member 200 and the lower fixing plate 300 by welding.

[0047] like Figure 1As shown, the support members 200 in this embodiment are arranged in two groups, the lower fixed plate 300 is located between the two groups of support members 200, and the two groups of support members 200 are arranged opposite to each other, each group of support members 200 is connected to a baffle 600, the two baffles 600 are arranged opposite to each other, the height of the baffle 600 is consistent with the height of the core 20 of the GIS lightning arrester, and the two ends of the upper fixed plate 100 are overlapped on the two baffles 600. In this embodiment, the number of support rods in each group of support members 200 is not specifically limited.

[0048] Further, the baffle 600 and the support member 200 can be integrally formed or welded, and the baffle 600 is located above the lower fixing plate 300, and the baffle 600 is configured to support the upper fixing plate 100. The upper fixing plate 100 can be placed on the baffle 600 and supported by the baffle 600. When the cover plate 30 of the GIS arrester core 20 is fixed to be flush with the upper end surface of the upper fixing plate 100, it can be determined that the horizontality of the GIS arrester core 20 meets the requirements.

[0049] like Figure 4-Figure 5 As shown, in this embodiment, the upper fixing plate 100 is provided with avoidance grooves 120 on both sides. When the upper fixing plate 100 is overlapped on the baffle 600, part of the support members 200 are placed in the avoidance grooves 120. The avoidance grooves 120 are used to avoid the support members 200 so that the upper fixing plate 100 can overlap on the baffle 600. At the same time, the number of avoidance grooves 120 on each side of the upper fixing plate 100 corresponds to the number of each group of support members 200. This embodiment does not specifically limit the shape of the avoidance grooves 120.

[0050] Optionally, the upper fixing plate 100, the support member 200 and the lower fixing plate 300 in this embodiment are all metal parts. For example, in order to reduce the weight of the core assembly and positioning tooling, the upper fixing plate 100, the support member 200 and the lower fixing plate 300 in this embodiment are all made of aluminum alloy.

[0051] In addition, the upper fixing plate 100 in this embodiment has various specifications to match the product models of different types of GIS lightning arresters. The first through hole 110 on the upper fixing plate 100 can also be matched with the cover plate 30 of the GIS lightning arrester core 20.
