The syndeton of a kind of net top-cross flow branching bus and its leading-out terminal and end of incoming cables
Technical field
The utility model relates to the syndeton of a kind of net top-cross flow branching bus and its leading-out terminal and end of incoming cables, the particularly a kind of net top-cross flow branching bus of great power conversion circuit unit and the syndeton of its leading-out terminal and end of incoming cables.
Background technology
Modern great power conversion circuit unit is usually by voltage regulating transformer, and rectifier transformer and rectifier constitute.The net top-cross flow branching bus current of aluminium electrolysis commutator change unit generally more than the training of 1 Wan An, exchanges branch bar and generally makes of copper busbar, links to each other with the transformer outlet terminal through the bus telescopic head.Because the size of transformer leading-out terminal is fixed, the transformer orbital plane and the rectifier installed surface of design are also definite, the ground size has deviation slightly when as the size of transformer leading-out terminal in the device fabrication process or rectifier end of incoming cables deviation or civil engineering being arranged slightly, will install to bus and bring difficulty even waste.
The utility model content
Technical problem to be solved in the utility model provides a kind of avoiding because the net top-cross flow branching bus of the inconvenience that the error that the rectifying transformer alternating leading-out terminal exchanges the end of incoming cables size in construction or the design with rectifier cabinet is brought to construction and installation and the syndeton of its leading-out terminal and end of incoming cables can overcome the deficiencies in the prior art.
The technical solution of the utility model is: it comprises the rectifier transformer leading-out terminal of an end, the rectifier cabinet end of incoming cables of the other end and middle rigid copper bus, the rectifier transformer leading-out terminal connects with the copper coin that is connected of their top and bottom by bolt respectively with the rectifier cabinet end of incoming cables, the connection steel plate of the top and bottom on both sides is connected with middle two rigid copper bus, connection soft copper band is set at rigid copper bus with being connected between the steel plate.
The soft copper band is a temperature-compensating soft copper band.
Compared with prior art, because the size of transformer leading-out terminal is fixed, the transformer orbital plane of design and rectifier installed surface are also definite.The ground size has deviation slightly when as the size of transformer leading-out terminal in the device fabrication process or rectifier end of incoming cables deviation or civil engineering being arranged slightly, will install to bus and bring difficulty even waste, this is suitable for novel because the utilization of soft copper band makes rigid copper bus straight, and is flexible during installation; The inconvenience that the error that while has been avoided owing to construction again or the rectifying transformer alternating leading-out terminal exchanges the end of incoming cables size in designing with rectifier cabinet is brought to construction and installation.Temperature-compensating soft copper band is established at turnover line two ends, can reduce arrangement terminal because of the vibration and the stress deformation that expands with heat and contract with cold.

Embodiment
Embodiment 1 of the present utility model: as shown in Figure 1, earlier with connecting copper coin 5 and rectifier transformer leading-out terminal 1 and rectifier cabinet end of incoming cables 2 bolted crimping, to connect 4 on 4 on copper coin 5 and soft copper band and rigid copper bus 3 and soft copper band all adopts powerful argon arc welding machine directly to weld, rigid copper bus 3 is straight busbar, for remedying the dislocation of 2 of rectifier transformer leading-out terminal 1 and rectifier cabinet ends of incoming cables, with the 4 processing simmering and bending adjustment of soft copper band, on two rigid copper bus 3, add cleat insulator 6, be used for suppressing 3 electric and magnetic oscillation voices of two rigid copper bus and in hole through walls, rise clamping and supporting role.
