A busbar system with compact commutation unit and boxless tap-off unit

Abstract

Disclosed is a bus system with a compact phase-changing unit and a box-free branching unit. The bus system comprises a phase-changing unit and a branching unit, wherein the phase-changing unit comprises an adapter front bus duct, an adapter rear bus duct, a first busbar adapter row, a second busbar adapter row, a fourth busbar adapter row, a fifth busbar adapter row, a polyester thin film, a sideplate and a cover plate; the branching unit comprises a branching plate, pile heads, pile head fixing blocks, a circuit breaker and a circuit breaker connecting piece; the adapter rear bus duct and the branching plate run through a branching plate positioning hole and the adapter rear bus duct through fasteners in sequence to realize fixation connection; the pile head bottom ends run through pilehead holes and the adapter rear bus duct in sequence to be fixedly connected with the busbar; and the circuit breaker runs through a circuit breaker connecting piece hole and a branching plate connecting hole in sequence through fasteners to realize fixation connection with the branching plate. The bus system integrates the phase-changing unit and the branching unit, so that the system function integration degree is high, the structure size is reduced, the safety performance is high, the structural connection strength is high, and the system structure is stable.

Description

technical field [0001] The invention belongs to the technical field of power distribution systems, in particular to a bus bar system with a compact phase commutation unit and a boxless tapping unit. Background technique [0002] With the emergence of modern engineering facilities and equipment, the power consumption of all walks of life is increasing rapidly, especially the emergence of many high-rise buildings and large workshops. The traditional cables used as power transmission wires can no longer meet the requirements in large current transmission systems. The parallel use of multiple cables brings a lot of inconvenience to the site installation and construction connection. As a new type of distribution wire, the busway came into being. Compared with the traditional cable, it fully demonstrates its superiority in the transmission of large currents. The contact resistance and temperature rise of the internal connection and the branch outlet socket, and high-quality insul...

Problems solved by technology

[0003] The main function of the low-voltage bus system is to conduct current. At the same time, in the actual installation process of the bus duct, it also needs to meet different installation and use requirements, such as the phase change function between the bus duct and the bus bar, and the tap function of the bus duct. , transfer function between bus ducts and many other requirements, among them, the commutation unit of bus duct is bulky, and the phase commutation unit uses fasteners to realize the connection between busbars, which is cumbersome to install and has potential safety hazards; the tap of bus duct The unit is also large in size, complex in internal structure, complex in manufacture and installation, easy to cause loosening of graded pile heads and busway, and low safety performance

There are also the following technical defects in the prior art: (1) The prior art fails to integrate the commutation unit and the tapping unit, so that the phase commutation function and the tapping function of the busway are integrated into one, forming a Low-voltage busbar system with busbar commutation and busbar tapping

(2) The commutation unit and tap unit of the bus duct are bulky, and the strength of the connection structure is low, and the safety performance is low
