Description

Technical Field

[0001] This utility model relates to the field of busbar technology, specifically an insulated busbar. Background Technology

[0002] With the emergence of modern engineering facilities and equipment, electricity consumption in all industries has increased rapidly. In particular, with the emergence of numerous high-rise buildings and large factory workshops, traditional cables, as power transmission conductors, can no longer meet the requirements of high-current transmission systems. The parallel use of multiple cables has brought many inconveniences to on-site installation and construction. Compared with traditional cables, busbar trunking fully demonstrates its superiority in high-current transmission.

[0003] Currently, most existing busbar trunking designs are compact busbar trunking. Compact busbar trunking has poor heat dissipation and is prone to overheating, which reduces the thermal stability and safe current carrying capacity of the busbar trunking. Over time and due to the degree of overheating, it causes aging of the insulation film, reduces the strength of the insulation strip, and may even lead to short circuit accidents, resulting in property damage and personal injury. Therefore, it is necessary to propose an insulated busbar trunking. Utility Model Content

[0004] To address the shortcomings of existing technologies, such as poor heat dissipation in existing busbar trunking which can accelerate insulation film aging and lead to safety accidents, this utility model proposes an insulated busbar trunking.

[0005] The technical solution adopted by this utility model to solve its technical problem is: an insulated busbar trunking, including a busbar trunking shell, the busbar trunking shell including a side plate and a sealing plate, the sealing plate being disposed on the opposite side of the side plate, end caps being fixedly connected to both ends of the busbar trunking shell, and a heat dissipation mechanism being provided in the inner cavity of the busbar trunking shell; The heat dissipation mechanism includes a fixing plate, which is fixedly connected to the opposite side of the sealing plate. A retaining sleeve is fixedly connected to the opposite side of the fixing plate. A busbar is clamped in the inner cavity of the retaining sleeve. An insulating film is provided on the outer wall of the busbar. The end of the busbar extends out of the outer side of the end cap. A first partition is provided on the opposite side of the side plate. A first ventilation hole is opened on the surface of the side plate. A second ventilation hole is opened on the surface of the first partition.

[0006] Preferably, the sealing plate is fixedly connected to the side edge of the side plate, and a second partition is provided on the opposite side of the sealing plate, with the end of the second partition contacting the opposite side of the side plate.

[0007] Preferably, the end of the first partition is in contact with the opposite side of the second partition, a gap is provided between the second partition and the sealing plate, and the fixing plate is fixedly connected to the opposite side of the second partition.

[0008] Preferably, the second partition has a third ventilation hole on its surface and the sealing plate has a fourth ventilation hole on its surface, with the third ventilation hole and the fourth ventilation hole being staggered.

[0009] Preferably, a gap is provided between the first partition and the side plate, and the first ventilation hole and the second ventilation hole are staggered.

[0010] Preferably, the top of the sleeve has a slot that extends through both sides of the sleeve, and the busbar is inserted into the inside of the slot.

[0011] Preferably, the card sleeve has a through hole on one side and a side hole on the other side, with the through hole penetrating both sides of the card sleeve and the side hole penetrating both ends of the card sleeve.

[0012] The advantages of this utility model are: This utility model divides the busbar trunking housing into side plates and sealing plates. A first partition is provided on the opposite side of the side plates. The ventilation and heat dissipation effect of the busbar trunking housing is enhanced by the first ventilation hole on the side plate and the second ventilation hole on the first partition.

[0017] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail. This application discloses an insulated busbar trunking. (Refer to...) Figures 1-5 An insulated busbar trunking includes a busbar trunking housing 1, which includes side plates 11 and end plates 12. The end plates 12 are disposed on opposite sides of the side plates 11. End caps 2 are fixedly connected to both ends of the busbar trunking housing 1. A heat dissipation mechanism 3 is provided in the inner cavity of the busbar trunking housing 1. By using the side plates 11 and end plates 12 to form the busbar trunking housing 1 and providing end caps 2 at both ends, the ventilation of the busbar trunking housing 1 is improved to enhance its heat dissipation effect. The heat dissipation mechanism 3 enhances the heat dissipation effect of the busbar 35 itself, thereby preventing the insulation film 36 from aging rapidly and causing safety accidents, and improving the service life of the insulation film 36. The heat dissipation mechanism 3 includes a fixing plate 31, which is fixedly connected to the opposite side of the sealing plate 12. A retaining sleeve 32 is fixedly connected to the opposite side of the fixing plate 31. A busbar 35 is clamped in the inner cavity of the retaining sleeve 32. An insulating film 36 is provided on the outer wall of the busbar 35. The end of the busbar 35 extends out of the outer side of the end cover 2. A first partition 13 is provided on the opposite side of the side plate 11. A first ventilation hole 14 is opened on the surface of the side plate 11. A second ventilation hole 15 is opened on the surface of the first partition 13. By utilizing the first ventilation hole 14 on the side plate 11 and the second ventilation hole 15 on the first partition 13, the ventilation and heat dissipation effect of the busbar housing 1 can be effectively improved. By setting the fixing plate 31 inside the upper and lower sealing plates 12, and clamping the busbar 35 with two opposite retaining sleeves 32 on the two fixing plates 31, the busbar 35 is suspended and installed, thereby improving the heat dissipation effect of the busbar 35, thereby preventing the insulation film 36 from aging rapidly and increasing the service life of the insulation film 36.

[0018] Reference Figure 1, Figure 2 and Figure 5 The sealing plate 12 is fixedly connected to the side edge of the side plate 11. A second partition 16 is provided on the opposite side of the sealing plate 12. The end of the second partition 16 contacts the opposite side of the side plate 11. The end of the first partition 13 contacts the opposite side of the second partition 16. A gap is provided between the second partition 16 and the sealing plate 12. A fixing plate 31 is fixedly connected to the opposite side of the second partition 16. A third ventilation hole 17 is provided on the surface of the second partition 16. A fourth ventilation hole 18 is provided on the surface of the sealing plate 12. The third ventilation hole 17 and the fourth ventilation hole 18 are offset. A gap is provided between the first partition 13 and the side plate 11. The first ventilation hole 14 and the second ventilation hole 15 are offset. The second partition 16 is provided on the inner side of the sealing plate 12. The gap between the second partition 16 and the sealing plate 12 can ensure ventilation stability. The ventilation of the sealing plate 12 is improved by the third ventilation hole 17 on the second partition 16 and the fourth ventilation hole 18 on the sealing plate 12. This further improves the ventilation and heat dissipation effect of the busbar trunking housing 1. The first ventilation hole 14 and the second ventilation hole 15 are staggered to reduce the probability of dust entering the busbar trunking housing 1 from the side plate 11. The third ventilation hole 17 and the fourth ventilation hole 18 are staggered to reduce the probability of dust entering the busbar trunking housing 1 from the sealing plate 12. This further improves the dustproof effect of the busbar trunking housing 1.

[0019] Reference Figure 2 , Figure 3 and Figure 4 The top of the sleeve 32 has a slot 33 that extends through both sides of the sleeve 32. The busbar 35 is inserted into the inside of the slot 33. One side of the sleeve 32 has a through hole 37 and the other side has a side hole 34. The through hole 37 extends through both sides of the sleeve 32 and the side hole 34 extends through both ends of the sleeve 32. The two sets of sleeves 32 are secured to the busbar 35 by the slots 33, allowing the busbar 35 to be suspended in the air, thereby increasing the contact area between the busbar 35 and the air and improving the heat dissipation effect. The through hole 37 is opened in the inner cavity of the sleeve 32 and the side hole 34 is opened on the side of the sleeve 32, thereby reducing the contact area between the sleeve 32 and the busbar 35 and further improving the heat dissipation effect of the busbar 35.

[0020] Working principle: In use, a complete busbar trunking is assembled using the side plate 11, the sealing plate 12, and the end cover 2. The ventilation of the busbar trunking housing 1 is improved to enhance its heat dissipation. The heat dissipation mechanism 3 further enhances the heat dissipation of the busbar 35 itself, thereby preventing the insulation film 36 from aging rapidly. The busbar 35 is secured in the slot 33 of the sleeve 32. The fixing plate 31, in conjunction with the sleeve 32, allows the busbar 35 to be suspended in the air, increasing the contact area between the busbar 35 and the air. The sleeve 32... The through hole 37 on the top, in conjunction with the side hole 34, reduces the contact area with the busbar 35, thereby improving the heat dissipation effect of the busbar 35. The first ventilation hole 14 on the side plate 11, in conjunction with the second ventilation hole 15 on the first partition plate 13, enhances the ventilation and heat dissipation effect of the side plate 11. The fourth ventilation hole 18 on the sealing plate 12, in conjunction with the third ventilation hole 17 on the second partition plate 16, enhances the ventilation and heat dissipation effect of the sealing plate 12. This achieves the purpose of preventing the insulation film 36 from aging rapidly and improves the service life of the insulation film 36.
