Description

Technical Field

[0001] The utility model relates to the technical field of voltage transformers, and particularly relates to a voltage transformer assembly for preventing frequent fusing of voltage transformer fuses. Background Technique

[0002] High-voltage fuses of voltage transformers often experience two-phase fusing. For the voltage transformer, internal coil short-circuit grounding, loose screws, damp wires, insulation damage leading to overheating, etc.; sleeve or external insulation breakage and discharge, or spark discharge and arcing phenomena can all cause fusing. Adding a voltage transformer at the neutral point of the voltage transformer can reduce the frequent fusing of the voltage transformer fuses caused by low-frequency oscillations in the system. Specifically, multiple voltage transformers are connected in a three-phase star connection through wires. This voltage transformer assembly is mainly used in power systems, especially those systems with a risk of low-frequency oscillations, to ensure that the voltage transformer can operate stably and reliably, reduce the frequency of fuse fusing, and thus ensure the safe and stable operation of the power system.

[0003] Under the existing technology, on the basis of solving the problem of frequent fusing of voltage transformer fuses, multiple voltage transformers are assembled on the same support base. Each voltage transformer needs to be locked and fixed to the installation base one by one through multiple groups of bolts or multiple groups of clamps to complete the sequential assembly. This operation is cumbersome and complex, and this method has poor stability and often loosens, leading to equipment failures and potential safety hazards. Content of the Utility Model

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0025] Please refer to Figures 1-3 , the present utility model provides a new technical solution: a voltage transformer assembly that prevents the fuse of the voltage transformer from frequently blowing, including a voltage transformer assembly housing 1, on which a plurality of voltage transformer assembly bodies 17 are provided, and a plurality of adjustment and fixing assemblies for fixing the voltage transformer assembly bodies 17 are provided on the voltage transformer assembly housing 1, and the adjustment and fixing assemblies are used to control and adjust the tightness of the voltage transformer assembly bodies 17;

[0026] The adjustment and fixing assemblies include a plurality of anti-slip convex blocks 4, springs 8, worms 10, worm gears 11, small gears 14 and racks 15;

[0027] The adjusting and fixing component further includes a first fixing post 2. Two clamping plates 3 are rotatably connected to the outer surface of the voltage transformer component housing 1. A plurality of anti-slip bumps 4 are fixedly connected to the opposite sides of the arc-shaped plates of the two clamping plates 3. The anti-slip bumps 4 are used to increase the friction force.

[0028] A worm gear shaft 5 is rotatably connected inside the voltage transformer component housing 1. A worm gear 11 is fixedly sleeved on the outer surface of the worm gear shaft 5.

[0029] Furthermore, a turntable 6 is fixedly sleeved on the outer surface of the worm gear shaft 5. Two rotating lock blocks 7 are rotatably connected to the upper surface of the turntable 6. The two rotating lock blocks 7 are adapted to the straight plates of the corresponding clamping plates 3. A spring 8 is fixedly connected between the straight plates of the two clamping plates 3.

[0030] Furthermore, two springs 8 are fixedly connected inside the voltage transformer component housing 1. A long shaft 9 is rotatably connected between the two springs 8.

[0031] Furthermore, a worm 10 is fixedly sleeved on the outer surface of the long shaft 9. The worm 10 is meshed with the worm gear 11. A bevel gear 13 is fixedly sleeved on the outer surface of the long shaft 9.

[0032] Furthermore, a gear shaft 12 is rotatably connected inside the voltage transformer component housing 1. The lower end of the gear shaft 12 is fixedly connected with a bevel gear 13 of the same kind. The two bevel gears 13 are meshed with each other.

[0033] Furthermore, a small gear 14 is fixedly sleeved on the upper end of the gear shaft 12. A sliding adjustment shell 18 is fixedly connected to the voltage transformer component housing 1. A rack 15 is slidably connected inside the sliding adjustment shell 18. A sliding button 16 is fixedly connected to the upper surface of the rack 15.

[0034] Furthermore, when in use, the voltage transformer component body 17 to be placed is slid by the sliding button 16. The sliding button 16 can drive the rack 15 to move inside the sliding adjustment shell 18. When moving, it can drive the small gear 14 to rotate through the teeth on it. When the small gear 14 rotates, it can drive the long shaft 9 on the other bevel gear 13 to rotate through the bevel gear 13 on the gear shaft 12. When the long shaft 9 rotates, it can drive the worm 10 to rotate. When the worm 10 rotates, it can drive the worm gear 11 and the turntable 6 on the worm gear shaft 5 to rotate slightly. When the turntable 6 rotates, it can drive the two clamping plates 3 to move closer to each other through the mutual approach of the rotating lock blocks 7 on it. At this time, the two clamping plates 3 can rotate around the axis of the first fixing post 2, so that the anti-slip bumps 4 on the two clamping plates 3 can move closer to each other, thereby firmly fixing the voltage transformer component body 17 therein.

[0035] Furthermore, by means of the provided adjusting and fixing assembly, the operator can control the tightness of the fixation of the voltage transformer component body 17 only through a simple sliding action, enabling effective control of the voltage transformer component body 17 without a complex operation process. This improves work efficiency, avoids problems such as complex operations and unstable fixation that may exist in traditional fixation methods, enhances safety, and also reduces equipment failures and potential safety hazards caused by frequent fuse blowing due to loosening, thereby improving the safety of the entire system.

[0036] Furthermore, the self-locking property of the worm 10 and the worm gear 11 provided in the adjusting and fixing assembly ensures that the voltage transformer component body 17 remains stable after being fixed, is not easily loosened by external factors, improves the stability and safety of the equipment, avoids problems such as complex operations and unstable fixation that may exist in traditional fixation methods, and reduces maintenance costs and time costs.

[0037] Working principle: When in use, the voltage transformer component body 17 to be placed is slid by the sliding button 16. The sliding button 16 can drive the rack 15 to move within the sliding adjustment housing 18. When moving, it can drive the small gear 14 to rotate through the teeth thereon. When the small gear 14 rotates, it can drive the long shaft 9 on another bevel gear 13 to rotate through the bevel gear 13 on the gear shaft 12. When the long shaft 9 rotates, it can drive the worm 10 to rotate. When the worm 10 rotates, it can drive the worm gear 11 and the turntable 6 on the worm gear shaft 5 to rotate slightly. When the turntable 6 rotates, the rotating lock blocks 7 thereon can move closer to each other, thereby driving the straight plates of the two clamping plates 3 to move closer to each other. At this time, the two clamping plates 3 can rotate around the axis of the first fixing column 2, so that the anti-slip protrusions 4 on the two clamping plates 3 can move closer to each other, thereby firmly fixing the voltage transformer component body 17 therein.
