Summary of the invention
The purpose of this utility model just there is provided a kind of Novel lapping structure made for a bus of drawer of low-voltage switch cabinet unit, and its technical scheme taked is:
This structure comprises switch cubicle unit drawer, is distributed in six groups of plug-in units of switch cubicle unit drawer internal upper part and is located at the breaker of plastic casing of bottom in switch cubicle unit drawer, this structure also comprises six roots of sensation multiply copper core cable, the two ends up and down of each multiply copper core cable are crimped with OT line nose respectively, the lower end of each multiply copper core cable is crimped on turnover line end corresponding on breaker of plastic casing respectively by OT line nose, and their upper end connects a corresponding plug-in unit respectively by OT line nose.
Or this structure comprises switch cubicle unit drawer, be distributed in six groups of plug-in units of switch cubicle unit drawer internal upper part, and be located at the breaker of plastic casing of bottom in switch cubicle unit drawer, this structure also comprises 12 multiply copper core cables and six overlap joint copper bars, the two ends up and down of each multiply copper core cable are crimped with OT line nose respectively, each multiply copper core cable is divided into six groups that match between two, the lower end often organizing multiply copper core cable connects one end of corresponding overlap joint copper bar respectively by OT line nose, their upper end connects a corresponding plug-in unit respectively by OT line nose, the other end of each overlap joint copper bar is separately fixed on turnover line end corresponding on breaker of plastic casing.
Or this structure comprises switch cubicle unit drawer, be distributed in six groups of plug-in units of switch cubicle unit drawer internal upper part, and be located at the breaker of plastic casing of bottom in switch cubicle unit drawer, this structure also comprises six overlap joint copper bar groups, each overlap joint copper bar group is respectively by upper overlap joint copper bar, transverse lap copper bar and lower overlap joint copper bar composition, wherein the lower end of upper overlap joint copper bar is fixedly connected with one end of transverse lap copper bar, the upper end of lower overlap joint copper bar is fixedly connected with the other end of transverse lap copper bar, in each overlap joint copper bar group, the upper end of upper overlap joint copper bar connects a corresponding plug-in unit, the horizontal bending in lower end of lower overlap joint copper bar in each overlap joint copper bar group, and be crimped on turnover line end corresponding on breaker of plastic casing.
As breaker of plastic casing rated current In≤225A, bus can be made by direct cable, as breaker of plastic casing rated current 225A < In < 630A, breaker outgoing line end tin-coated copper bar overlaps, overlap joint row again with cable bond, a cable nose is replaced directly to be pressed in breaker of plastic casing leading-out terminal, the cable other end is directly pressed on the line busbar of drawer, good insulation preformance, particularly when requiring through current transformer, cable is easily out of shape, convenient processing.As breaker of plastic casing rated current In >=630A, all make bus with tin-coated copper bar.
This bridging arrangement can be used in the production of the low-tension switch cabinets such as MNS, GCS, GCK, substantially increases production efficiency and switch cabinet drawer unit insulating capacity, and the reliability of safe operation.
