Description

Technical Field

[0001] This utility model belongs to the field of busbar technology, and in particular relates to a busbar with safety protection function. Background Technology

[0002] Busbar trunking, as a key piece of equipment for power transmission, is widely used in the power supply systems of various buildings, industrial plants, and large equipment. It is mainly responsible for efficiently distributing power from the power source to various electrical devices, playing an important role as a bridge and link in the power transmission process.

[0003] In existing busbar structures, the common configuration consists of a simple outer shell enclosing conductive busbars, with an insulating filler layer covering the busbars, through which electrical energy is transported. However, existing busbar systems have the following drawbacks in practical use:

[0004] First, existing busbar trunking has poor structural sealing, allowing dust and moisture from the external environment to easily intrude, affecting the normal operation of the conductive busbars and potentially causing short circuits and other malfunctions. Second, existing busbar trunking relies solely on natural heat dissipation from the outer casing or has only a few ventilation holes, lacking a dedicated ventilation mechanism to enhance heat dissipation. Furthermore, existing busbar trunking cannot flexibly adjust the airflow entry and exit points according to the complex installation environment during heat dissipation, and the extraction and exhaust processes may interfere with other surrounding equipment, leading to unstable equipment operation.

[0005] Therefore, it is essential to invent a busbar trunking system with safety protection features. Utility Model Content

[0006] To address the above problems, this utility model proposes a busbar trunking with safety protection function. The technical solution used is as follows:

[0007] A busbar trunking system with safety protection features includes a sleeve, a cover plate, a ventilation mechanism, side plates, a heat-conducting plate, an insulating filling layer, and a conductive busbar. The sleeve has a cover plate bolted to both ends, and through holes are provided on the sides of each sleeve. A corresponding ventilation mechanism is installed at each through hole, and these mechanisms are bolted to the corresponding positions on the sleeve. The sleeve has four side plates inside, forming a hollow cylinder, with adjacent side plates bolted together. A heat dissipation cavity is provided between each side plate and the corresponding inner wall of the sleeve. An insulating filling layer is fixed inside the hollow cylinder formed by the side plates, and a conductive busbar is fixed inside the insulating filling layer, with both ends of the conductive busbar sealed through the corresponding cover plate. A heat-conducting plate is fixed to each side plate, with its two ends positioned on opposite sides of the side plate.

[0008] Furthermore, the ventilation mechanism includes guide rails, baffles, mounting plates, and fans. Two guide rails are provided, each bolted to a sleeve on one side of the through hole. Several baffles are slidably mounted on the guide rails, and two mounting plates are bolted to the guide rails. Fans are bolted to each mounting plate, with one fan's output facing the heat dissipation cavity between the sleeve and the side plate, and the other fan facing outwards from the sleeve. The total length of all baffles and mounting plates is equal to the length of the through hole on the sleeve. This arrangement allows for heat dissipation of the heat dissipation cavity through gas flow. Furthermore, the positions of the air intake and exhaust can be adjusted according to the actual installation environment, thereby preventing interference with other external equipment caused by air extraction and exhaust.

[0009] Furthermore, the heat-conducting plate includes a heat-absorbing plate, heat-dissipating fins, and a sealing ring. The heat-absorbing plate is fixed to the inner wall of the side plate, and the side of the heat-absorbing plate is fitted with the insulating filling layer. Several heat-dissipating fins are fixed to the side of the heat-absorbing plate, and the heat-dissipating fins move through the side plate. Each heat-dissipating fin is fitted with a sealing ring, which is fitted with the side plate. This arrangement can transfer the heat of the insulating filling layer to the interior of the heat dissipation cavity.

[0010] Furthermore, the side plate is shaped like a "U", and two corresponding side plates are symmetrically arranged. Two other symmetrical side plates are fixed between the two side plates by bolts. This arrangement can seal the outer surface of the insulating filling layer and the conductive busbar.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] In practical use, the four side plates and two cover plates work together to form a sealed protection between the insulating filling layer and the middle of the conductive busbar, effectively preventing external environmental factors from interfering with the normal operation of the conductive busbar. Secondly, the heat-conducting plate can transfer the heat generated by the insulating filling layer to the heat dissipation cavity, and then the ventilation mechanism can dissipate the heat in the heat dissipation cavity, thereby preventing the conductive busbar from being damaged due to overheating. The ventilation mechanism can flexibly adjust the position of the air intake and exhaust according to the actual installation environment, avoiding adverse effects on other external equipment during the air extraction and exhaust process.

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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0023] In the description of this utility model, it should be understood that the terms "upper", "middle", "outer", "inner", "around", etc., which indicate orientation or positional relationship, are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0024] Please see Figures 1 to 6As shown, this utility model is a busbar trunking with safety protection function, including a sleeve 1, a cover plate 2, a ventilation mechanism 3, side plates 4, a heat-conducting plate 5, an insulating filling layer 6, and a conductive busbar 7. The two ends of the sleeve 1 are respectively fixed to the cover plate 2 by bolts, and the sides of the sleeve 1 are all provided with through holes, and the corresponding ventilation mechanism 3 is provided at the position of each through hole. The ventilation mechanism 3 is fixed to the corresponding position of the sleeve 1 by bolts. The inside of the sleeve 1 is provided with four side plates 4, which form a hollow cylinder, and the adjacent side plates 4 are fixedly connected by bolts. A heat dissipation cavity is provided between the side plates 4 and the corresponding inner wall of the sleeve 1. The hollow cylinder formed by the side plates 4 is fixed with an insulating filling layer 6, and the conductive busbar 7 is fixed inside the insulating filling layer 6. The two ends of the conductive busbar 7 are sealed through the corresponding cover plate 2. The side plates 4 are all fixed with heat-conducting plates 5, and the two ends of the heat-conducting plates 5 are respectively provided on both sides of the side plates 4.

[0025] Specifically, the ventilation mechanism 3 includes a guide rail 31, baffles 32, mounting plates 33, and fans 34. Two guide rails 31 are provided, each fixed to a sleeve 1 on one side of the through hole by bolts. Several baffles 32 are slidably mounted on the guide rails 31, and two mounting plates 33 are fixed to the guide rails 31 by bolts. Fans 34 are fixed to each mounting plate 33 by bolts. One fan 34's output end faces the heat dissipation cavity between the sleeve 1 and the side plate 4, while the other fan 34 faces outwards from the sleeve 1. The total length of all baffles 32 and mounting plates 33 is equal to the length of the through hole in the sleeve 1. During use, one fan 34 can draw in external cold air into the heat dissipation cavity, and then the other fan 34 draws out the gas from the heat dissipation cavity, thus cooling the interior of the cavity through the airflow. Furthermore, the position of the baffles 32 can be changed according to the actual installation environment, and the mounting plates 33 can be fixed to the notches of the baffles 32, thereby preventing the air extraction and exhaust from interfering with other external equipment.

[0026] Specifically, the heat-conducting plate 5 includes a heat-absorbing plate 51, heat dissipation fins 52, and a sealing ring 53. The heat-absorbing plate 51 is fixed to the inner wall of the side plate 4, and the side of the heat-absorbing plate 51 is attached to the insulating filling layer 6. Several heat dissipation fins 52 are fixed to the side of the heat-absorbing plate 51, and the heat dissipation fins 52 move through the side plate 4. Each heat dissipation fin 52 is fitted with a sealing ring 53, which is attached to the side plate 4. When in use, the heat-absorbing plate 51 can absorb the heat of the insulating filling layer 6 and conduct it to the heat dissipation fins 52. The sealing ring 53 can seal the heat dissipation fins 52 and the side plate 4, thereby preventing gas or liquid inside the heat dissipation cavity from entering the hollow cylinder formed by the side plate 4.

[0027] Specifically, the side plate 4 is shaped like a "U", and two corresponding side plates 4 are symmetrically arranged. Two other symmetrical side plates 4 are fixed between the two side plates 4 by bolts. When in use, the hollow cylinder composed of the four side plates 4 can seal the outer surface of the insulating filling layer 6 and the conductive busbar 7.

[0028] Please see Figure 1-6 As shown, this utility model is a busbar trunking with safety protection function. Its working principle is as follows: During installation, the two ends of the conductive busbar 7 are first electrically connected to the corresponding external equipment, and then the sleeve 1 is fixed to the external support frame by bolts. During use, the conductive busbar 7 can conduct electricity to the corresponding external equipment. The insulating filling layer 6 can prevent the conductive busbar 7 from short-circuiting. In addition, the heat-conducting plate 5 can absorb the heat on the insulating filling layer 6 and conduct it into the heat dissipation cavity. Then, the ventilation mechanism 3 dissipates heat into the heat dissipation cavity.
