Description

Technical Field

[0001] The utility model relates to elastic equipment, in particular to an energy storage spring component of a solid insulation switch operating mechanism. Background Art

[0002] Due to the small installation space of existing solid insulated switches, the energy storage spring has always interfered with surrounding components such as the opening coil, closing coil, closing push plate and disconnector pull rod during the closing process, thereby affecting the overall performance of the mechanism. In addition, the switch sometimes fails to close properly due to fatigue failure of the energy storage spring at the site of use. During maintenance, the spring mechanism can only be replaced as a whole, which increases the workload and difficulty of after-sales service and increases the product cost. Due to the small remaining space of solid insulated switch products, it is difficult to improve the above situation even if the spring operating mechanism is redesigned. Utility Model Content

[0003] The technical problem to be solved by the utility model is to provide a solid insulated switch operating mechanism energy storage spring assembly which can avoid interference with surrounding parts, reduce the impact on the switch mechanism at the moment when the mechanism closing action is completed, and reduce the after-sales workload and difficulty.

[0004] In order to solve the above technical problems, this application provides the following technical solutions:

[0005] The utility model discloses an energy storage spring assembly for an operating mechanism of a solid insulated switch, comprising a spring body, a first pull plate, a second pull plate, and a core shaft, wherein the core shaft is clamped in the spring body, the core shaft is coaxially arranged with the spring body, one end of the spring body is connected with the first pull plate, and the other end is connected with the second pull plate, gaps are left between the core shaft and the first pull plate and the second pull plate, and when the spring body is stretched toward one end, the core shaft is driven to move synchronously, and the first pull plate and the second pull plate are both used to be connected to the solid insulated switch.

[0006] Furthermore, the first pull plate and the second pull plate have the same structure, wherein the first pull plate includes a pull plate body and a spring connecting end which are connected to each other, the pull plate body is a thin plate, the spring connecting end is a cylinder, and the outer wall of the spring connecting end is provided with a receiving groove for accommodating the spring body, and the two ends of the spring body are respectively accommodated in the receiving groove of one of the spring connecting ends.

[0007] Furthermore, the pull plate body is provided with a through hole, and the through hole is used to connect the first pull plate to the solid insulating switch element.

[0008] Furthermore, the spring body and the spring connecting end of the first pull plate and the spring connecting end of the second pull plate are welded to each other.

[0009] Compared with the prior art, the energy storage spring assembly of the solid insulated switch operating mechanism of the utility model has at least the following beneficial effects:

[0010] The energy storage spring assembly of the solid insulated switch operating mechanism of the utility model comprises a spring body and a core shaft, and the core shaft is clamped in the spring body. After the core shaft is clamped in the spring body, the core shaft has a certain rigidity, so the amplitude of the radial vibration of the spring body can be effectively reduced to avoid interference with surrounding parts. At the same time, at the moment after the closing action of the mechanism is completed, the spring body still has excess energy to be released, and the core shaft can resist and accept the excess energy, so as to avoid the impact on the solid insulated switch mechanism as a whole. In addition, when energy storage failure occurs, there is no need to disassemble the spring assembly as a whole, and only the spring body needs to be replaced, which not only reduces the cost but also greatly reduces the after-sales workload.

[0011] The energy storage spring assembly of the solid insulated switch operating mechanism of the utility model is further described below in conjunction with the accompanying drawings. BRIEF DESCRIPTION OF THE DRAWINGS

[0015] like Figure 1 As shown, the utility model is a solid insulated switch operating mechanism energy storage spring assembly, including a spring body 11, a first pull plate 12, a second pull plate 13, and a core shaft 14. The core shaft 14 is clamped in the spring body 11, and the core shaft 14 is coaxially arranged with the spring body 11. One end of the spring body 11 is connected to the first pull plate 12, and the other end is connected to the second pull plate 13. There is a gap between the core shaft 14 and the first pull plate 12 and the second pull plate 13. When the spring body 11 is stretched toward one end, it drives the core shaft 14 to move synchronously. The first pull plate 12 and the second pull plate 13 are both used to connect to the solid insulated switch. When in use, the utility model is connected to the solid insulated switch by the first pull plate 12 and the second pull plate 13. Figure 2 , Figure 3As shown, the energy storage spring assembly of the solid insulated switch operating mechanism is surrounded by the opening coil 21, the closing coil 22, the closing push plate 23 and other components. Specifically, the core shaft 14 is made of a material with a certain rigidity. The energy storage spring assembly of the solid insulated switch operating mechanism of the utility model includes a spring body 11 and a core shaft 14. The core shaft 14 is clamped in the spring body 11. After the core shaft 14 is clamped in the spring body 11, the core shaft 14 has a certain rigidity, which can effectively reduce the amplitude of the radial vibration of the spring body and avoid interference with surrounding parts. At the same time, at the moment after the closing action of the mechanism is completed, the spring body still has excess energy to be released, and the core shaft can resist and accept this excess energy, so as to avoid the solid insulated switch mechanism as a whole from being impacted. In addition, when the energy storage fails, there is no need to disassemble the spring assembly as a whole, and only the spring body needs to be replaced, which not only reduces the cost but also greatly reduces the after-sales workload.

[0016] Optionally, the first pull plate 12 and the second pull plate 13 have the same structure, wherein the first pull plate 12 includes a pull plate body 121 and a spring connecting end 122 that are connected to each other, the pull plate body 121 is a thin plate, the spring connecting end 122 is a cylinder, and the outer wall of the spring connecting end 122 is provided with a receiving groove for accommodating the spring body 11, and the two ends of the spring body 11 are respectively accommodated in a receiving groove of a spring connecting end 122.

[0017] Optionally, a through hole 123 is provided on the pull plate body 121, and the through hole 123 is used to connect the first pull plate 12 to the solid insulated switch element. Specifically, the pull plate body 121 of the first pull plate 12 is connected to the solid insulated switch mounting plate by screws, and the pull plate body of the second pull plate 13 is connected to the closing push plate. By providing the through hole 123 on the pull plate body 121, the energy storage spring assembly of the solid insulated switch operating mechanism of the utility model is more convenient to install.

[0018] Optionally, the spring body 11 and the spring connection end 122 of the first pull plate 12 and the spring connection end of the second pull plate 13 are welded to each other.
