Description

Technical Field

[0001] This utility model relates to the field of high-voltage power equipment technology, specifically a high-voltage phase-matching auxiliary vehicle. Background Technology

[0002] A phase-matching vehicle is a specialized vehicle that integrates phase-matching testing instruments and related auxiliary equipment. It is mainly used in power systems to confirm whether the phases of different power sources or lines are consistent. It can operate in places such as high-voltage power lines and substations, and quickly complete phase-matching operations through professional testing methods. It provides phase matching basis for power system grid connection, switching operations, and power restoration after line maintenance, and is an important mobile testing device to ensure the safe and stable operation of the power system.

[0003] The primary moving contact system in traditional voltage transformer trolleys has a significant defect: the rear end of the clover contact is usually rigidly connected to the primary conductive rod, which is then directly fixed to the insulating sleeve. This rigid structure means that when the trolley is pushed forward, the clover contact cannot effectively absorb and buffer the impact energy when it collides with the stationary contact (busbar drum). This huge instantaneous mechanical impact force is directly transmitted to the entire contact system, which can easily cause plastic deformation of the clover contact fingers, severe wear of the surface silver plating layer, and even damage to the substrate. Over a long period of time, this problem will drastically reduce the mechanical and electrical life of the clover contact, posing a potential hazard to the stable operation of the equipment. Utility Model Content

[0004] The purpose of this invention is to provide a high-pressure nucleation auxiliary vehicle to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A high-voltage phase-matching auxiliary vehicle includes a phase-matching auxiliary vehicle body. A connected insulator is fixedly connected to the front of the phase-matching auxiliary vehicle body. An insulating sleeve is fixedly connected to the front end of the connected insulator. A buffer mechanism is provided on the inner wall of the insulating sleeve. An installation mechanism is provided on the front of the buffer mechanism. A staggered contact piece is provided on the front of the installation mechanism.

[0007] The buffer mechanism includes a support cylinder, which is fixedly connected to the inner wall of an insulating sleeve. A spring is fixedly connected to the inner wall of the support cylinder. A round block is fixedly connected to the front end of the spring. A support shaft is fixedly connected to the front of the round block. A support plate is fixedly connected to the inner wall of the insulating sleeve. A sliding sleeve is fixedly connected to the side of the support plate away from the inner wall of the insulating sleeve.

[0008] The outer wall shape of the circular block matches the inner wall shape of the support cylinder, and the circular block is slidably connected to the inner wall of the support cylinder, so that the circular block can move stably and compress the spring.

[0009] The support cylinder has a through hole on its front side, and the support shaft passes through the through hole, allowing the support shaft to move through the through hole.

[0010] The inner wall shape of the sliding sleeve matches the outer wall shape of the support shaft, and the support shaft is slidably connected to the inner wall of the sliding sleeve, so that the support shaft can slide and be limited within the inner wall of the sliding sleeve.

[0011] The installation mechanism includes an internally threaded cylinder, which is fixedly connected to the front end of the support shaft. An externally threaded head is threadedly connected to the inner wall of the internally threaded cylinder. A primary contact arm is fixedly connected to the front end of the externally threaded head. A torsion sleeve is fixedly connected to the outer wall of the primary contact arm, which facilitates the disassembly and replacement of the plum blossom contact piece.

[0012] The outer wall of the torsion sleeve is fixedly connected with protrusions, which are distributed in a circumferential array to facilitate the rotation of the torsion sleeve by the protrusions.

[0013] The primary contact arm is fixedly connected to the rear side of the plum blossom contact piece. The front of the insulating sleeve has a circular opening, and the diameter of the circular opening is larger than the diameter of the twist sleeve. When the plum blossom contact piece moves backward, the opening is used for the twist sleeve and the protrusion to move.

[0014] Compared with the prior art, this utility model provides a high-voltage nucleation auxiliary vehicle, which has the following beneficial effects:

[0015] 1. This utility model, through its buffer mechanism, converts the enormous impact kinetic energy generated when the plum blossom contact plate contacts the stationary contact into the elastic potential energy of the spring, and ultimately dissipates it as heat energy through the relative sliding friction between the circular block and the inner wall of the support cylinder, and between the support shaft and the inner wall of the sliding sleeve. This mechanical buffering process effectively absorbs collision energy, reduces the rigid impact at the moment of contact, thereby significantly reducing the stress and wear of the plum blossom contact plate and its connecting components, effectively extending the mechanical and electrical life of the key contact components of the nuclear phase auxiliary vehicle, and ensuring the stability and safety of equipment operation;

[0016] 2. This utility model, through its installation mechanism, adopts a threaded connection installation mechanism consisting of an internal threaded cylinder, an external threaded head, a primary contact arm, and a twist sleeve, realizing modular and rapid assembly and disassembly of the plum blossom contact pieces. Operators only need to rotate the twist sleeve at the front of the insulating sleeve to complete the contact replacement, completely isolating the replacement operation outside the high-voltage chamber. No disassembly of the insulating sleeve or the coupled insulator is required, simplifying the maintenance process, shortening the power outage time, and improving the maintenance efficiency and operational safety of phase verification operations.

[0022] 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.

[0023] This utility model provides the following technical solution:

[0024] Example 1

[0025] Combination Figures 1 to 4 A high-voltage phase-matching auxiliary vehicle includes a phase-matching auxiliary vehicle body 1. A connected insulator 2 is fixedly connected to the front of the phase-matching auxiliary vehicle body 1. An insulating sleeve 3 is fixedly connected to the front end of the connected insulator 2. A buffer mechanism 6 is provided on the inner wall of the insulating sleeve 3. An installation mechanism 5 is provided on the front of the buffer mechanism 6. A plum blossom contact piece 4 is provided on the front of the installation mechanism 5. By integrating the buffer mechanism 6 and the quick-disassembly and assembly installation mechanism 5 into the interior of the insulating sleeve 3, a modular front-end contact system is formed, which realizes effective buffering of the impact during phase-matching operation and convenient replacement of contacts, thereby improving the service life of the equipment and the efficiency of operation and maintenance.

[0026] The buffer mechanism 6 includes a support cylinder 61, which is fixedly connected to the inner wall of the insulating sleeve 3. A spring 62 is fixedly connected to the inner wall of the support cylinder 61. A round block 63 is fixedly connected to the front end of the spring 62. A support shaft 64 is fixedly connected to the front of the round block 63. A support plate 65 is fixedly connected to the inner wall of the insulating sleeve 3. A sliding sleeve 66 is fixedly connected to the side of the support plate 65 away from the inner wall of the insulating sleeve 3. By utilizing the compression energy stored in the spring 62 and the sliding friction between the round block 63 and the support shaft 64, the instantaneous impact force is smoothly converted into elastic potential energy and heat energy and dissipated, effectively protecting key components such as the integrated insulator 2 from rigid collision damage.

[0027] The outer wall shape of the circular block 63 matches the inner wall shape of the support cylinder 61. The circular block 63 is slidably connected to the inner wall of the support cylinder 61. The precise sliding fit between the circular block 63 and the inner wall of the support cylinder 61 provides a stable and reliable axial guide for the compression and rebound of the spring 62, preventing the components from deviating or jamming during movement, and ensuring the smoothness and linearity of the buffer action.

[0028] The support cylinder 61 has a through hole on its front side, through which the support shaft 64 passes. The through hole provides a channel for the support shaft 64 to pass through the front wall of the support cylinder 61, and at the same time, it radially limits the movement of the support shaft 64, ensuring that the axial impact force on the support shaft 64 can be effectively and without loss transmitted to the internal spring 62.

[0029] The inner wall shape of the sliding sleeve 66 matches the outer wall shape of the support shaft 64. The support shaft 64 is slidably connected to the inner wall of the sliding sleeve 66. The sliding sleeve 66 provides a second support and guide point for the front end of the support shaft 64. Together with the support cylinder 61, it forms a statically indeterminate stable guide system, which enhances the bending stiffness and motion stability of the support shaft 64, and further improves the smoothness of the buffering process and the friction energy dissipation effect.

[0030] Example 2

[0031] See Figures 1 to 4 Furthermore, based on Embodiment 1, the installation mechanism 5 further includes an internal threaded cylinder 51, which is fixedly connected to the front end of the support shaft 64. An external threaded head 52 is threadedly connected to the inner wall of the internal threaded cylinder 51, and a primary contact arm 53 is fixedly connected to the front end of the external threaded head 52. A torsion sleeve 54 is fixedly connected to the outer wall of the primary contact arm 53. This achieves mechanical decoupling between the plum blossom contact piece 4 and the buffer mechanism 6, allowing the contact part to be quickly disassembled and assembled as an independent module, thus solving the problem of inconvenient replacement of traditional welding or integrated structures.

[0032] The outer wall of the torque sleeve 54 has protrusions that are fixedly connected and are distributed in a circumferential array. The protrusion design of the outer circumferential array of the torque sleeve 54 increases the friction and force application points during operation. Even when wearing thick gloves, it can be easily gripped and sufficient torque can be applied for twisting, which improves the ergonomics and convenience of disassembly and installation operations.

[0033] The primary contact arm 53 is fixedly connected to the rear side of the plum blossom contact piece 4. The front of the insulating sleeve 3 has a circular opening, and the diameter of the circular opening is larger than the diameter of the twist sleeve 54. The enlarged circular opening provides the necessary movement space for the twist sleeve 54 and the primary contact arm 53 connected to it to move backward during the buffering process, avoiding interference and collision with the end face of the insulating sleeve 3, ensuring the integrity of the buffering stroke and the freedom of the mechanism's movement.

[0034] In actual operation, when this device is used, when the plum blossom contact piece 4 contacts the stationary contact, the plum blossom contact piece 4 will move backward, pushing the support shaft 64 to move through the mounting mechanism 5. The support shaft 64 can drive the round block 63 to slide on the inner wall of the support cylinder 61, and the round block 63 can compress the spring 62, thereby converting the impact force of the contact into the elastic potential energy of the spring 62, and then into the frictional heat energy of the round block 63, thus achieving the purpose of buffering. At the same time, the support shaft 64 can slide and limit itself on the inner wall of the sliding sleeve 66, further ensuring friction and achieving a good buffering effect.

[0035] The rotating sleeve 54 drives the primary contact arm 53 to rotate, so that the external thread head 52 can be unscrewed from the inner wall of the internal thread cylinder 51, thereby realizing the disassembly of the plum blossom contact piece 4. During long-term use, it is convenient to disassemble and replace the plum blossom contact piece 4.
