Description

Technical Field

[0001] The utility model relates to the technical field of busbar trunking processing, in particular to a compact busbar trunking. Background Technique

[0002] A busbar trunking, also known as an electrical busbar, is a metal device used to transmit electric energy. It is usually composed of busbar columns made of copper or aluminum and enclosed in a metal shell. Its main function is to distribute a large amount of power to each component in a distributed system. Especially in indoor low-voltage power transmission trunk line engineering projects, busbar trunkings have increasingly replaced traditional wires and cables. In the power system, busbar trunkings are often used to connect the loop between the transformer and the incoming line cabinet or low-voltage cabinet, playing the role of power connection. In addition, it is also applicable to low-voltage distribution room power supply circuits, horizontal power distribution trunks, and building shaft power distribution, etc.

[0003] After retrieval, it is found that a Chinese patent with the application number 202221933275.7 discloses a compact busbar trunking, including a busbar trunking body. The busbar trunking body includes a fixing frame and a support frame. One end of the fixing frame and the support frame is fixed with a fixing plate. The fixing plate is fixed with a first connection mechanism and a second connection mechanism. The second connection mechanism is installed inside the first connection mechanism. The first connection mechanism cooperates with the second connection mechanism. One end of the fixing frame and the support frame is provided with an opening. A sealing plate is movably installed on the inner wall of the opening. A handle is fixed on the sealing plate. In this compact busbar trunking, the angle between the fixing frame and the support frame is finely adjusted by rotating through the connection mechanism. After fine adjustment, the connection mechanisms are arc-connected, and the connection position is sealed to prevent external impurities from entering the inside of the fixing frame and the support frame and causing an impact.
