Double-loop intelligent rack bus system

Abstract

A double-loop intelligent rack bus system comprises starting end boxes, bus ducts, bus bars, connectors, plugging devices, plugging boxes, power distribution cabinets and power strips. The number of the starting end boxes is two, and the starting end boxes are respectively arranged at two ends of the bus ducts. The bus ducts are arranged in a double-layer overlapping manner; the bus bars in each section of bus duct are connected end to end through the connectors; the plugging device is arranged on one side of each layer of bus duct, and the plugging device is electrically connected with the bus bar; each plugging box is fixed with the two ends of the bus duct through plugging, and the plugging boxes are electrically connected with the plugging devices; The power distribution cabinets are arranged on the bottom side of the bus duct, the power strips are fixedly arranged in the power distribution cabinets, and the power strips are electrically connected with the plugging boxes through cables. According to the bus system, structural design is carried out on the bus duct, the plugging device and the plugging box, the bus system has a more compact system structure, plugging and unplugging of the plugging box can be facilitated, and operation is convenient; electric arcs are avoided in the power taking process in the system, and high safety performance is achieved.

Description

technical field [0001] The invention relates to the field of busbar systems, in particular to a dual-circuit intelligent rack busbar system. Background technique [0002] The busway is a closed metal device composed of copper and aluminum busbar columns, which is used to distribute large power to various components of the decentralized system. It has increasingly replaced wires and cables in indoor low-voltage power transmission trunk line projects. In the power distribution room system, in order to distribute power to multiple distribution cabinets conveniently, the bus duct structure is used as the carrier of power transmission. However, the general structural space in the power distribution room is relatively compact, and good line planning for the bus duct structure is required. , Design and installation, adapt to the narrow space environment, and at the same time, the busway can be easily connected to the distribution cabinet. There are many defects in the existing tra...

AI Technical Summary

Problems solved by technology

(1) The arrangement of the busbars in the busbar system is also usually a single-way arrangement, and a single channel is used for power transmission. When multi-channel power transmission is required, it is necessary to set up multiple sets of busway structures, and use multiple sets of busway structures. Multiple groups of corresponding assembly structures are assembled separately, which greatly increases the complexity of the busway assembly, and the installation convenience is poor, and the multi-way busway structure that is assembled separately takes up a lot of space

(2) For the installation of plug-in boxes in different busway structures, in order to avoid the obstruction between the plug-in box and the busway, it is necessary to install the plug-in box on different operating surfaces of the busway, which is inconvenient for operators to plug in The same operation of receiving the box

(3) The plug-in box of the existing traditional busbar system is inserted into the busbar, and fixed with a clamp or front and rear locking feet. The fixing process of the plug-in box is cumbersome, and it is not very convenient to disassemble. Unable to achieve quick plug-in and disassembly of the plug-in box

The process of contacting the plug-in device with the busbar to take power, and the process of contacting the plug-in device with the plug-in box to get power are prone to arcing, which greatly affects the safety performance of the busway and the plug-in box , the plug-in box cannot be arbitrarily plugged in at any time
