The invention provides a bus end connecting metal ware and a using method thereof. The bus end connecting metal ware comprises an upper jaw part, a lower jaw part and a cam; wherein the cam is arranged at inside of the upper jaw part and furthermore two ends of the cam are hinged with two ends of the upper jaw part. The lower jaw part is arranged between the upper jaw part and the cam and furthermore two ends of the lower jaw part are hinged with two ends of the upper jaw part. The upper jaw part comprises an upper jaw plate, a first side plate and a second side plate; wherein the upper ends of the first side plate and the second side plate are respectively with two ends of the upper jaw plate for forming a U-shaped chamber. The lower surface of one end of the upper jaw plate is provided with an upper jaw oblique opening. The bus end connecting metal ware has advantages of simple structure, high practicability and convenient operation. The bus end connecting metal ware can be widely used for connection between a transformer station bus end and a plate-shaped connector.
Description
technical field [0001] The invention relates to a connection structure at the end of a busbar, in particular to a fitting for connecting a busbar end and a method for using the same. Background technique [0002] At present, one type of conductive pipe busbar used in power transmission lines in China is to process the rectangular connection surface of the round bar busbar end by washing and planing, and then connect to each other through the rectangular surface. Generally, it is not detachable and belongs to hard busbar overcurrent. Since the new generation of smart substation cancels the isolating switch on the busbar side, in order to avoid the need to stop other electrical equipment at the same time when the isolating circuit breaker is overhauled, it is necessary to change the hard busbar overcurrent to the soft wire overcurrent. [0003] Among the flexible wire connecting fittings used in the existing foreign substations, the common type of the pipe bus connector is con...
