Description

Technical Field

[0001] This utility model relates to the field of power engineering technology, specifically to an integrated disconnecting switch conductive circuit structure for outdoor high-voltage circuit breakers. Background Technology

[0002] In outdoor high-voltage power transmission and distribution systems, disconnect switches, as an important component of circuit breakers, play a crucial role in establishing visible insulation breaks and ensuring maintenance safety. Traditional outdoor disconnect switches often employ a split-type structure design for their conductive circuits, with their contact system, insulation support mechanism, and operating mechanism arranged separately.

[0003] The components of the split structure rely on multiple connections. Under long-term outdoor wind vibration, temperature difference deformation and operational impact, the structure is prone to loosening, which leads to contact pressure imbalance, increased contact resistance, and risks of local overheating or even ablation. In addition, the torsional stiffness of the traditional single-pillar support structure is limited, and the pillar is prone to tilting under extreme weather conditions, affecting the alignment accuracy of the moving and stationary contacts. At the same time, the distributed structure requires regular tightening and verification of each connection node, and the contact system maintenance requires disassembling multiple sets of components, which is time-consuming and carries the risk of misassembly.

[0004] The existing rotary transmission system of the conductive circuit of outdoor disconnect switches mostly adopts multi-stage linkage and gear set cooperation. The long transmission chain leads to large mechanical losses and asynchronous opening and closing. Especially in low temperature environment, the change of lubricant viscosity can easily cause a sharp increase in operating torque, which poses a risk of failure to operate. In addition, the exposed rotating shaft lacks a sealing design, and the intrusion of sand and dust can easily accelerate the wear of components.

[0005] Therefore, in order to address the above problems, the applicant needs to design an integrated disconnect switch conductive circuit structure for outdoor high-voltage circuit breakers to solve the problem. Utility Model Content

[0006] The purpose of this utility model is to provide an integrated disconnecting switch conductive circuit structure for outdoor high-voltage circuit breakers to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: an integrated disconnecting switch conductive circuit structure for outdoor high-voltage circuit breakers, including a base,

[0008] It also includes: a bracket set on the base, and a support member is fixedly set on the bracket, a first pillar is fixedly set on the support member, and a contact seat is set on the first pillar;

[0009] A conductive component is mounted on a support, and the conductive component includes a second support column. A connecting plate is fixedly mounted on the second support column, and a stabilizing seat is fixedly mounted on the connecting plate. A fixing rod is fixedly mounted on the stabilizing seat, and a rotating component is rotatably mounted on the fixing rod. A contact is rotatably mounted on the rotating component, and the contact is adapted to a contact seat. A connecting component is mounted on the rotating component, and a control component is mounted on the connecting component. The control component works with the connecting component to drive the rotating component to rotate.

[0010] Furthermore, the connecting component includes a rotating shaft rotatably connected to the rotating component, and a pull rod is fixedly mounted on the rotating shaft. A linkage block is provided at the end of the pull rod away from the rotating shaft, and a linkage shaft is fixedly mounted on the linkage block. A rotating plate is rotatably mounted on the linkage shaft, and the rotating plate is fixedly connected to the control component.

[0011] Furthermore, the control component includes a mounting plate fixedly connected to the bracket, and a rotating rod is rotatably mounted on the mounting plate, with the rotating rod fixedly connected to the rotating plate.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] This integrated disconnect switch's conductive circuit structure significantly improves the operational performance and reliability of outdoor high-voltage equipment through its integrated design. Employing a dual-support architecture and a linked rotary system, it enhances mechanical stability within a compact layout, effectively resisting vibration and stress deformation in complex outdoor environments. Simultaneously, the composite insulation sleeve, through layered material combinations, forms a dual barrier against arcing and flashover, greatly enhancing electrical safety.

The contact and contact seat mating structure, combined with a guiding design, optimizes contact pressure distribution, ensuring low-impedance conduction of the conductive circuit. The overall structure saves installation space while extending maintenance cycles, meeting the power grid's requirements for long lifespan, maintenance-free operation, and high environmental adaptability of outdoor switchgear.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] like Figures 1-5 As shown, the present invention discloses an integrated disconnecting switch conductive circuit structure for an outdoor high-voltage circuit breaker, comprising a base 1, and further comprising: a bracket 10 disposed on the base 1, wherein a support member 11 is fixedly disposed on the bracket 10, a first pillar portion 12 is fixedly disposed on the support member 11, and a contact seat 13 is disposed on the first pillar portion 12; a conductive component 2 disposed on the bracket 10, wherein the conductive component 2 includes a second pillar portion 21, a connecting plate 22 is fixedly disposed on the second pillar portion 21, a stabilizing seat 23 is fixedly disposed on the connecting plate 22, a fixing rod 24 is fixedly disposed on the stabilizing seat 23, and a rotating member 25 is rotatably disposed on the fixing rod 24, a contact 250 is rotatably disposed on the rotating member 25, and the contact 250 is adapted to the contact seat 13; a connecting component is disposed on the rotating member 25, and a control component 28 is disposed on the connecting component, the control component 28 cooperating with the connecting component to drive the rotating member 25 to rotate.

[0025] The connecting component includes a rotating shaft 26 rotatably connected to the rotating component 25, and a tie rod 27 is fixedly mounted on the rotating shaft 26. A linkage block 270 is provided at the end of the tie rod 27 away from the rotating shaft 26, and a linkage shaft 271 is fixedly mounted on the linkage block 270. A rotating plate 272 is rotatably mounted on the linkage shaft 271, and the rotating plate 272 is fixedly connected to the control component 28. The rotational motion is converted into linear displacement through the cooperation of the linkage block 270 and the linkage shaft 271, and then converted into circumferential rotation through the rotating shaft 26, forming an efficient transmission chain and reducing mechanical losses.

[0026] The control component 28 includes a mounting plate 280 fixedly connected to the bracket 10. A rotating rod 281 is rotatably mounted on the mounting plate 280 and is fixedly connected to a rotating plate 272. The fixed connection between the mounting plate 280 and the rotating rod 281 forms a rigid support base. Combined with the direct transmission between the rotating plate 272 and the rotating rod 281, the stability of torque transmission is enhanced. The axial rotation of the rotating rod 281 is constrained by the mounting plate 280, which avoids the influence of eccentric load on the transmission mechanism, further suppresses the vibration caused by operational impact, thereby extending the service life of the transmission components and ensuring the smoothness and repeatability of the opening and closing actions.

[0027] A connecting plate 282 is fixedly installed at one end of the rotating rod 281. A connecting piece 283 is fixedly installed on the connecting plate 282, and the connecting piece 283 is fixedly connected to an external switch. The fixed connection between the connecting plate 282 and the rotating rod 281 achieves seamless docking with the external switch. The external switch can easily control the rotation of the connecting plate 282, and the rotation of the connecting plate 282 will easily drive the rotating rod 281 to rotate.

[0028] A second support member 20 is fixedly installed below the second pillar 21, and the second support member 20 is fixedly connected to the bracket 10. The fixed connection between the second support member 20 and the bracket 10 provides additional support for the second pillar 21. Together with the first support member 11, they form a double support structure. Through bidirectional constraint, the mechanical stability of the conductive component 2 is enhanced, stress concentration is dispersed during opening and closing operations, and structural deformation caused by strong outdoor winds, vibrations, or operational impacts is suppressed. This ensures that the contact pressure between the contact 250 and the contact seat 13 is evenly distributed, thereby maintaining the low impedance characteristics of the conductive circuit.

[0029] The rotating rod 281 is surrounded by a composite insulating sleeve, which consists of an inner rubber layer and an outer silicone rubber shed. The layered composite structure of the inner rubber layer and the outer silicone rubber shed forms a double insulation protection system: the inner rubber layer compensates for the assembly tolerance between the rotating rod 281 and the mounting plate 280 through elastic deformation, avoiding partial discharge; the alternating rib structure of the outer silicone rubber shed significantly extends the creepage distance and maintains high pollution level tolerance in salt spray and polluted environments, thereby effectively resisting the risk of arc erosion and flashover, and improving the electrical safety of the equipment in humid and highly polluted outdoor environments.

[0030] Working Principle: When using the integrated disconnecting switch conductive circuit structure of this outdoor high-voltage circuit breaker, in the open state, an isolation break is formed between contact 250 and contact base 13. The composite insulating sleeve and the air gap constitute a double insulating medium, which can withstand the impact of short-circuit current. The entire operation process is achieved by a mechanical self-locking mechanism to maintain the position, without the need for continuous operating force input. Combined with a fully sealed bearing unit, it ensures a long mechanical life under harsh environmental temperatures, achieving maintenance-free operation under harsh outdoor conditions. When an external switch is driven through connector 283, the connecting plate 282... The rotating rod 281 rotates axially on the mounting plate 280. The rotating rod 281 transmits torque to the linkage shaft 271 through the rotating plate 272 fixedly connected to it, forcing the linkage block 270 to pull the rod 27 to produce linear displacement. This displacement is converted into circumferential rotation of the rotating member 25 through the rotating shaft 26, and finally drives the contact 250 to achieve precise opening and closing action with the contact seat 13 along the guide trajectory. The operation is convenient, thereby extending the maintenance cycle while saving installation space, and meeting the power grid's requirements for long service life, maintenance-free operation and high environmental adaptability of outdoor switchgear.

[0031] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
