Description

Technical Field

[0001] This invention relates to the field of busbar technology, and more specifically, to a busbar that is easy to install and its installation method. Background Technology

[0002] In the field of power transmission trunk lines, busbar trunking is a substitute for power cables. It is a closed metal device made of copper or aluminum busbar columns, used to distribute large amounts of power among various components of the system. The busbar trunking system is a highly efficient power distribution device for transmitting current. It has increasingly replaced wires and cables in indoor low-voltage power transmission trunk line projects. Today, it has become an indispensable wiring method in high-rise buildings, factory electrical equipment, and power systems, and the demand is increasing year by year.

[0003] Existing busbar trunking is relatively complex to install, and is generally installed in the factory and then transported to the construction site for installation. Due to the large size of the finished busbar trunking, transportation and storage are inconvenient and the transportation and storage costs are high.

[0004] Therefore, a new technical solution is urgently needed to solve the above-mentioned technical problems. Summary of the Invention

[0005] In view of the shortcomings of the existing technology, the purpose of this invention is to provide a busbar trunking that is easy to install and its installation method.

The mounting plates are provided with bends at 45° to the plane of the mounting plates on both sides. The bends of two adjacent mounting plates are fixedly connected by a first bolt. The outer frame is also provided with a conductive plate and a positioning plate for positioning the conductive plate.

[0007] By adopting the above technical solution, the mounting plates, conductive plates and connectors can be stored and transported before the busbar trunking is installed. They are then manually assembled at the construction site. The four identical mounting plates are assembled by the first bolt through a 45° bend, and the conductive plates are positioned by the positioning component. By transporting and storing the detachable parts separately, the production and transportation costs are greatly reduced.

[0008] The present invention is further configured such that: the connector includes an upper U-shaped frame and a lower U-shaped frame, the upper U-shaped frame and the lower U-shaped frame are fixedly connected by a second bolt, and the outer edge of the bent portion of the mounting plate abuts against the four corners of the connector.

[0009] The invention is further configured such that: the inner surface of the mounting plate is provided with a wedge-shaped groove penetrating through its two end sidewalls; the bottom of the positioning plate is provided with a first wedge-shaped block slidably connected in the wedge-shaped groove; the surface of the positioning plate is provided with a plurality of positioning grooves; and the positioning plate is provided with two plates and is provided with a top and a bottom within an outer frame.

[0010] The present invention is further configured such that: the inner walls on both sides of the upper U-shaped frame are provided with fixing blocks, and the two ends of the fixing blocks are provided with second wedge blocks inserted into the wedge grooves.

[0011] The present invention is further configured such that: a threaded groove for threaded connection of a second bolt is provided on one side of the second wedge block.

[0012] The present invention is further configured such that: the top inner wall of the upper U-shaped frame and the bottom inner wall of the lower U-shaped frame are provided with an abutting block, the abutting block being located at one end of the first wedge block.

[0013] The present invention is further configured such that the positioning plate is made of an insulating material.

[0014] The present invention is further configured such that: a U-shaped pad is provided in the positioning groove, and the U-shaped pad is made of an insulating elastic material.

[0028] As shown in the figure, a busbar trunking that is easy to install includes an outer frame 1 composed of four mounting plates 3, and a connector 2 between two adjacent outer frames. The mounting plates have bends 4 at 45° to the plane of the mounting plates on both sides. The bends of two adjacent mounting plates are fixedly connected by a first bolt 5. The bends have three evenly spaced screw holes 6 along their length for the first bolt to fix them. The outer frame also has a conductive plate 7 and a positioning plate 8 for positioning the conductive plate 7.

[0029] Before the busbar trunking is installed, the mounting plates, conductive plates 7 and connectors can be stored and transported. When they are delivered to the construction site, they are assembled manually. The four identical mounting plates are assembled by the first bolt through the 45° bend and the conductive plates 7 are positioned by the positioning parts.

During installation, the second wedge blocks 16 are inserted into the wedge grooves 12 of the mounting plates on both sides to improve the stability between the connector and the outer frame and ensure the stability of the connection between adjacent busbars.

[0033] The second wedge block 16 has a threaded groove 17 on one side for the second bolt 11 to be threaded. By tightening the second bolt 11, it passes through the mounting plate and is screwed into the threaded groove 17, thereby further improving the stability of the connection between the connector and the housing.

[0034] The upper U-shaped frame 9 has an abutment block 18 on its top inner wall and the lower U-shaped frame 10 has an abutment block 18 on its bottom inner wall. The abutment block 18 is located at one end of the first wedge block 13. After installation, the two ends of the abutment block abut against the ends of the two first wedge blocks 13 respectively, so as to fix the positioning block.

[0035] The positioning plate 8 is made of insulating material, and a U-shaped pad 19 is provided in the positioning groove 14. The U-shaped pad 19 is made of insulating elastic material. By setting the U-shaped pad 19, the conductive plate 7 is inserted into the U-shaped pad 19 to ensure the stability of the conductive plate 7.
