Description

Technical Field

[0001] The utility model relates to an air-cooling bus duct with a multiple protection structure. Background Art

[0002] Bus duct is a metal device made of copper and aluminum busbars. It mainly consists of copper bars, insulators, brackets, bus boxes, low-voltage cabinets and other components. It is used to distribute high power to various components of the distributed system. It has increasingly replaced wires and cables in indoor low-voltage power transmission trunk line projects.

[0003] Bus ducts are usually designed with certain mechanical shocks and external impacts in mind, so they usually have a certain impact resistance. If the impact is small, the bus duct may only have slight surface scratches or dents without causing significant impact on the internal conductors or overall performance. In extreme cases, strong impacts may cause the structural integrity of the bus duct to be severely damaged or even broken. Such damage may cause power transmission interruption and pose a serious safety hazard.

[0004] Therefore, an air-cooled bus duct with a multiple protection structure is needed, which can maintain the structural integrity of the bus duct when it is subjected to strong impact in extreme conditions. Utility Model Content

[0005] The purpose of the utility model is to solve the above shortcomings of the prior art and provide an air-cooled bus duct with multiple protection structures. The bus duct body is protected by setting a shell and a protection unit. The following is a specific solution:

[0006] An air-cooled bus duct with a multiple protection structure comprises a main body, an outer shell and a protection unit. The main body is provided with a mounting frame, the outer shell is sleeved on the main body through the mounting frame, the outer shell is provided with a plurality of inlay grooves, and the protection unit is arranged in the inlay grooves.

[0007] In order to more conveniently install the mounting frame, the mounting frame is provided on both the upper and lower sides of the main body, and the mounting frame is provided with a plurality of mounting notches.

[0008] In order to more conveniently fix the mounting frame, the shell is provided with a mounting protrusion that cooperates with the mounting notch, and both the mounting protrusion and the mounting notch are provided with threaded holes. The shell and the mounting frame are fixed by a connecting plate, and the connecting plate is installed above the threaded hole.

[0009] In order to ensure the installation strength of the protection unit, the inlay groove is a quadrilateral, the depth of the inlay groove is half of the thickness of the protection unit, and the protection unit is fixed in the inlay groove by an adhesive or a bolt structure.

[0010] In order to increase the protection range of the shell, the length of the main body is m centimeters, and the length of the shell is m+20 centimeters. The lengths of the main body and the shell can be controlled by changing the value of m.

[0011] By increasing the number of inlay grooves, personnel can install the protection unit in different positions according to actual needs, thereby reducing material waste. Inlay grooves are provided on the four sides of the shell, and the inlay grooves are evenly arranged on the surface of the shell. At least 6 inlay grooves are provided on any one side.

[0012] Furthermore, the upper surface of the protection unit is square, and a buffer portion is provided inside the protection unit.

[0013] In order to increase the buffering performance, the buffering part is composed of a plurality of arches, and the material of the buffering part is a high-toughness metal.

[0014] In order to increase the cushioning performance, two arches are provided.

[0015] In order to reduce the complexity of the structure and lower the cost, the buffer part is composed of an acute angle steel, and the material of the angle steel is a high-toughness metal.

[0016] Beneficial effect: The bus duct body is protected by the cooperation of the shell and the protection unit, so that personnel can install only the shell and install the protection unit on the shell as needed, which increases flexibility. Through the cooperation of the two, the bus duct can maintain structural integrity under extreme impact to reduce the direct impact of the impact on the conductor. BRIEF DESCRIPTION OF THE DRAWINGS
