[0002] In power transmission and distribution systems, busbar trunking, as a highly efficient and reliable power transmission device, is widely used in the power distribution systems of various industrial, commercial, and civil buildings. It safely and stably transmits electrical energy from the power source to various electrical devices, making it an indispensable and important component of the power system.
[0003] With the continuous growth of electricity demand and the increasing demands for the safety and reliability of power systems, higher requirements are being placed on the performance of busbar trunking. Insulation performance is one of the key indicators for evaluating the quality of busbar trunking. Good insulation performance can effectively prevent faults such as current leakage and short circuits, ensuring the safe operation of the power system and avoiding personal injury and property damage caused by electrical accidents.
[0004] However, existing busbar structures still have some shortcomings in terms of insulation performance. Due to unreasonable structural design, some busbars suffer from poor sealing between internal components, allowing dust, moisture, and other impurities to enter the busbar. These impurities adhere to the busbars, reducing their insulation performance and increasing the risk of electrical faults. Furthermore, in some busbars, the connections between components are not tight enough during assembly, leaving gaps that also affect insulation. Moreover, existing busbars are inconvenient to inspect and maintain. Inspection or repair often requires disassembling numerous components, making the process cumbersome and increasing maintenance costs and time. Utility Model Content

[0021] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.
[0022] Example
[0023] like Figures 1 to 4 As shown, a high-insulation busbar trunking structure includes an outer top plate 11, an outer bottom plate 12 at the bottom of the outer top plate 11, a fixing sealing plate 13 on one side of the outer bottom plate 12 and on the other side of the outer top plate 11, a maintenance sealing plate 14 on the other side of the outer bottom plate 12 and on the other side of the outer top plate 11, end caps 15 at both ends of the bottom of the outer top plate 11, top blocks 16 at both ends of the top of the outer bottom plate 12, and pads 17 fitted on the top and bottom of the fixing sealing plate 13.
[0024] The outer top plate 11 has linear square grooves 111 on both sides, top screws 112 at both ends of the top of the outer top plate 11, and pressure blocks 113 at the bottom of the outer top plate 11 and at the bottom of the top screws 112.
[0025] The outer bottom plate 12 is also provided with linear square grooves 111 on both sides, and the linear square grooves 111 on both sides of the outer top plate 11 are located on the same vertical line as those on both sides of the outer bottom plate 12.
[0026] The fixed sealing plate 13 includes a side plate 131 near the outer top plate 11. The top and bottom of the side plate 131 are provided with square clips 132. The other side of the side plate 131 is provided with multiple parallel connecting ribs 133. The other side of the connecting ribs 133 is provided with a mounting plate 134. The top and bottom of the side wall of the mounting plate 134 are provided with multiple mounting holes 135.
[0027] Mounting hole 135 is set to correspond to pad 17.
[0028] A square locking block 132 is also provided on the top of one side of the inspection sealing plate 14. The top and bottom of the inspection sealing plate 14 are embedded with sliding grooves 141, which are slidably connected to one side of the linear square groove 111.
[0029] The end cap 15 has a slot 151 at one end, and the inner wall of the end cap 15 is slidably connected to the outer wall of the top block 16.
[0030] It should be noted that in this embodiment, the outer top plate 11 is generally elongated, with linear square grooves 111 on both sides. These linear square grooves 111 are used to engage and position with the square locking blocks 132. At both ends of the top of the outer top plate 11, pressing screws 112 are installed. The pressing screws 112 are connected to the outer top plate 11 by threaded connection. At the bottom of the outer top plate 11 and at the bottom position of the pressing screws 112, a pressure block 113 is provided. When the pressing screws 112 are rotated, the pressing screws 112 will push the pressure block 113 downward, thereby pressing and fixing the internal busbars and other components, ensuring that the busbars are stably placed in the busbar groove and preventing the electrical performance from being affected by shaking.
[0031] The outer bottom plate 12 is also long and narrow, with linear square grooves 111 on both sides. The linear square grooves 111 on both sides of the outer top plate 11 and the linear square grooves 111 on both sides of the outer bottom plate 12 are located on the same vertical line. This design makes the fit between the components more precise during the assembly of the busbar, which is conducive to improving the stability and sealing of the overall structure.
[0032] The outer base plate 12 has top blocks 16 at both ends for cooperating with the end cap 15 to achieve end sealing and positioning. In addition, the end cap 15 has a slot 151 at one end for facilitating the introduction and exit of the busbar. The inner wall of the end cap 15 is slidably connected to the outer wall of the top block 16. During assembly, the end cap 15 is fitted onto the top block 16, and the end cap 15 is installed through sliding cooperation, thereby sealing the end of the busbar trough and preventing dust, moisture, etc. from entering the busbar trough and affecting the insulation performance and service life of the busbar. As the upper and lower clamping process proceeds, the slot 151 becomes smaller and smaller. Finally, when the top pressing screw 112 is rotated, the top pressing screw 112 will push the pressing block 113 downward to achieve the pressing and fixing of the internal busbar and other components, ensuring the stability of the busbar in the busbar trough.
[0033] The fixed sealing plate 13 includes a side plate 131 near the outer top plate 11. The top and bottom of the side plate 131 are provided with square clips 132. During assembly, the square clips 132 will be inserted into the corresponding slots on the outer top plate 11 and the outer bottom plate 12 to achieve initial fixation of the fixed sealing plate 13 to the outer top plate 11 and the outer bottom plate 12. The other side of the side plate 131 is provided with multiple parallel connecting ribs 133, which enhance the overall strength of the fixed sealing plate 13. The other side of the connecting ribs 133 is provided with a mounting plate 134. The bottom and top of the side wall of the mounting plate 134 are provided with multiple mounting holes 135, which are correspondingly provided with pads 17. By passing fasteners such as bolts through the mounting holes 135 and pads 17, the fixed sealing plate 13 can be firmly installed on one side of the outer top plate 11 and the outer bottom plate 12 to achieve the closure of one end of the busbar trunking. The use of plastic pads 17 to separate the busbar box from the housing or wall of the installed equipment further increases the protection.
[0034] The top of one side of the maintenance sealing plate 14 is also provided with a square locking block 132, which is used to cooperate with the locking grooves on the outer top plate 11 and the outer bottom plate 12; the bottom and top of the maintenance sealing plate 14 are embedded with sliding grooves 141, which are slidably connected to one side of the linear square groove 111; when it is necessary to inspect the inside of the busbar trunking, the maintenance sealing plate 14 can be slid along the sliding groove 141 and the linear square groove 111 to open one side of the busbar trunking, making it convenient for operators to carry out inspection and maintenance work; after the inspection is completed, the maintenance sealing plate 14 is slid back to its original position to achieve a seal.
[0035] In practical applications, the outer top plate 11 and outer bottom plate 12 are first placed in parallel. Then, the fixing sealing plate 13 and the maintenance sealing plate 14 are installed on both sides of the outer top plate 11 and outer bottom plate 12, respectively. The initial positioning is achieved by the cooperation of the square locking block 132 and the sliding groove 141 with the linear square groove 111. Next, the fixing sealing plate 13 is firmly installed using bolts and other fasteners, and the maintenance sealing plate 14 is adjusted to a suitable position. After that, the busbar is placed between the outer top plate 11 and outer bottom plate 12, and the pressure block 113 is pushed to press the busbar by rotating the top pressing screw 112. Finally, the end cap 15 is installed on the top block 16 to complete the assembly of the entire busbar trunking structure.
[0036] The above embodiments are only for illustrating the technical concept of this utility model and should not be construed as limiting the scope of protection of this utility model. Any modifications made to the technical solution based on the technical concept proposed by this utility model shall fall within the scope of protection of this utility model.
