Phase dislocation preventing device for accurate connection of bus duct

Abstract

The invention discloses a phase dislocation preventing device for accurate connection of a bus duct. The phase dislocation preventing device comprises two bus cover plates, two bus side plates and a copper bar, wherein the two bus side plates are arranged at the two ends of the inner sides of the two bus cover plates and are fixedly connected with the two bus cover plates by virtue of first bolts, the copper bar is arranged in a cavity formed by the two bus cover plates and the two bus side plates, and heat dissipating plates are arranged outside the two bus side plates respectively. The invention provides a phase dislocation preventing device for accurate connection of the bus duct. According to the device, placing pore passages in a second sliding plate and a fourth sliding plate are respectively matched with a first fixing column and a second fixing column, so that phase sequence identification and mounting of the bus duct are further facilitated; meanwhile, phase sequence connection accuracy in a bus duct mounting process is enhanced, so that accuracy of mounting the copper bar in the bus duct is improved, security of the copper bar is improved, and the probability that a phase sequence error and an accident appear in the bus duct mounting process and workload of workers during subsequent maintenance are reduced.

Description

technical field [0001] The invention relates to the technical field of bus duct connection, in particular to a phase error prevention device for precise connection of bus ducts. Background technique [0002] Busway, a kind of power transmission equipment, with the emergence of modern engineering facilities and equipment, busway, as a new type of distribution wire, fully demonstrates its superiority in large current transmission, and the use of busway reduces the traditional cable connection. The resistance and temperature of the circuit improve the safety and reliability, and make the environment of the whole circuit system more perfect. [0003] At present, when the bus duct is installed and used, both ends of the bus duct are made the same, and some bus ducts do not have a phase sequence mark, which will affect the installation of the staff, thereby reducing the work efficiency of the staff. If the personnel do not recognize the phase sequence of the bus duct and install ...

Problems solved by technology

[0003] At present, when the bus duct is installed and used, both ends of the bus duct are made the same, and some bus ducts do not have a phase sequence mark, which will affect the installation of the staff, thereby reducing the work efficiency of the staff. If the personnel do not recognize the phase sequence of the bus duct and install the wrong phase, it will lead to failure after the bus duct is powered on, and in severe cases, it will lead to accidents. Some bus ducts will paste some phase sequence marking paper on the bus cover to distinguish , the marking paper will fall off during the transportation or installation of the bus duct, which will increase the workload of the staff during subsequent maintenance
