Technical Field

[0001] This utility model relates to the field of substation busbar technology, and in particular to a structure for preventing loosening of substation busbar connecting bolts. Background Technology

[0002] Substation busbars are the core conductive components connecting various electrical equipment within a substation, primarily responsible for the collection, distribution, and transmission of electrical energy. They are manufactured using copper, aluminum, or copper alloys and must meet requirements for high conductivity and mechanical strength. Based on power supply reliability requirements, they can be classified into three types: single busbar, double busbar, and ring busbar. Double busbar systems utilize bus tie switches to achieve fault isolation and load transfer. The design must comprehensively consider current load capacity, arc thermal protection, and safety grounding measures, and ensure operational stability through voltage monitoring systems and protection devices.

[0003] While the above technologies have achieved stable operation of the protection device, in actual use, when the busbars of the substation are connected by bolts, there is a risk of the bolts loosening over time, which is inconvenient to use.

[0030] 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.

[0031] Reference Figures 1-3An embodiment of this utility model provides a substation busbar connection bolt anti-loosening fastening structure, including a busbar plate 1, a top screw anti-loosening component 2 provided at the rear end of the busbar plate 1, side screw anti-loosening components 3 provided on the front and rear sides of the rear end of the busbar plate 1, and a dustproof component 4 provided on the top of the top screw anti-loosening component 2.

[0032] The top screw anti-loosening assembly 2 includes a support frame 21 that supports the foundation. The front end of the support frame 21 has a slot 22 for installing a heat dissipation shield 28. The heat dissipation shield 28, which can tightly fit the screw, is slidably connected inside the slot 22. The front end of the heat dissipation shield 28 is fixedly connected to an anti-slip plate 29 that enhances friction. The bottom of the support frame 21 is fixedly connected to a locking post 24 that cooperates with a slot 25 to limit displacement. The top of the busbar board 1 is fixedly connected to a heat dissipation plate 26 that assists in heat dissipation. The top of the heat dissipation plate 26 has a groove 27 for accommodating a spring 23. A slot 25 is provided at the top. The bottom of the support frame 21 is elastically connected to the inside of the groove 27 by a spring 23. The outer wall of the locking post 24 is slidably connected to the inside of the slot 25. The bottom of the heat dissipation baffle 28 is attached to the screw on the top of the heat dissipation plate 26 to prevent the screw from loosening. One end of the spring 23 is fixedly connected to the bottom of the support frame 21, and the other end of the spring 23 is fixedly connected to the inside of the groove 27. In the top screw anti-loosening assembly 2, the support frame 21 is elastically connected to the groove 27 of the heat dissipation plate 26 by the spring 23. The cooperation between the locking post 24 and the slot 25 restricts the lateral displacement of the support frame 21. Under the action of the spring 23, the support frame 21 always has downward pressure, which causes the heat dissipation baffle 28 to be tightly attached to the screw on the top of the heat dissipation plate 26. The anti-slip plate 29 further enhances the friction and prevents the screw from loosening through continuous axial pressure.

[0033] Reference Figures 2-4The side screw anti-loosening assembly 3 includes a second heat sink 31. The outer wall of the second heat sink 31 has a groove 32 for sliding the second support frame 34. The second support frame 34 is elastically connected inside the groove 32 via a return spring 33, providing thrust. A slot 38 is provided on the left side of the second support frame 34, and a heat dissipation baffle 36 is slidably connected inside the slot 38 to fit the side screw. An anti-slip strip 37 is fixedly connected to the front end of the heat dissipation baffle 36 to enhance anti-slip effect. A sliding column 35 is fixedly connected to the rear wall of the second support frame 34. The return spring 33... One end is fixedly connected to the inside of the slide groove 32, and the other end of the return spring 33 is fixedly connected to the rear wall of the second support frame 34. The rear wall of the second heat sink 31 is fixedly connected to the front and rear sides of the rear end of the busbar 1 by screws. The outer wall of the second heat sink 31 has an opening, and the outer wall of the slide column 35 is slidably connected to the inside of the opening to ensure the sliding trajectory. The side screw anti-loosening component 3 elastically connects the second support frame 34 to the slide groove 32 of the second heat sink 31 through the return spring 33. The cooperation between the slide column 35 and the opening ensures that the second support frame 34 slides stably. The spring force of the return spring 33 ensures that the second support frame 34 always has a forward thrust, causing the heat dissipation baffle 36 to fit tightly against the screw on the rear wall of the second heat dissipation plate 31. The anti-slip strip 37 enhances the anti-slip effect and forms continuous pressure on the screw from the side to prevent it from loosening. The dustproof component 4 includes a filter screen 41 that can filter dust. The bottom of the filter screen 41 is fixedly connected to a sliding strip 42. The top of the support frame 21 has a slide rail 43 for the sliding strip 42 to slide. The sliding strip 42 is slidably connected inside the slide rail 43, which facilitates the installation and removal of the filter screen 41. The bottom of the filter screen 41 fits against the top of the support frame 21. The filter screen 41 is slidably connected to the slide rail 43 on the top of the support frame 21 through the sliding strip 42. The filter screen 41 fits tightly against the top of the support frame 21, which can effectively prevent dust from entering the interior of the top screw anti-loosening component 2, avoiding dust accumulation that affects the screw connection stability and heat dissipation effect. At the same time, the cooperation between the sliding strip 42 and the slide rail 43 facilitates the disassembly, cleaning and replacement of the filter screen 41.

[0034] Working principle: During use, in the top screw anti-loosening assembly 2, the support frame 21 is elastically connected to the groove 27 of the heat sink 26 by the spring 23. The cooperation between the locking post 24 and the locking groove 25 restricts the lateral displacement of the support frame 21. Under the elastic force of the spring 23, the support frame 21 always has downward pressure, which drives the heat dissipation shield 28 to fit tightly against the screw on the top of the heat sink 26. The anti-slip plate 29 further enhances the friction and prevents the screw from loosening through continuous axial pressure. The side screw anti-loosening assembly 3 elastically connects the second support frame 34 to the slide groove 32 of the second heat sink 31 by the return spring 33. The cooperation between the sliding post 35 and the opening ensures the stable sliding of the second support frame 34. The elastic force of the return spring 33 ensures that the second support frame 34 always has a forward thrust, causing the heat dissipation baffle 36 to fit tightly against the screw on the rear wall of the second heat dissipation plate 31. The anti-slip strip 37 enhances the anti-slip effect and applies continuous pressure to the screw from the side to prevent it from loosening. The filter screen 41 is slidably connected to the slide rail 43 on the top of the support frame 21 through the sliding strip 42. The filter screen 41 fits tightly against the top of the support frame 21, which can effectively block dust from entering the top screw anti-loosening component 2 and prevent dust accumulation from affecting the screw connection stability and heat dissipation effect. At the same time, the cooperation between the sliding strip 42 and the slide rail 43 facilitates the disassembly, cleaning and replacement of the filter screen 41.
