Description
Technical field.、
The utility model relates to the dedicated devices in a kind of low-voltage complete switch equipment, be specifically related to a kind of 100A and the following bus box that is used for the multilayer wiring that the medium and small electric current 1/2 unit drawer of draw out switchgear MCC cabinet uses, the utility model also relates to the circuit distribution adapter that this bus box is housed.
Background technology
According to the Electrical Appliances Designing requirement, the circuit distribution adapter has three-phase or three-phase and four-line two classes, and A, B, C three-phase and A, B, C, two kinds of wirings of N three-phase and four-line are arranged in the circuit distribution adapter.The once turnover line of the circuit distribution adapter of existing little electric current 1/2 unit drawer all adopts individual layer plane formula wires design, and at present the circuit distribution adapter of using is moulded two kinds of shell structure 1/2 element circuit distribution adapter and metal shell structure 1/2 unit drawer circuit distribution adapter:
1, mould shell structure 1/2 element circuit distribution adapter (hereinafter to be referred as adapter), the adapter of this kind version has only domestic GCS type pull-out type low-voltage complete switch equipment and the MNS of ABB AB type pull-out type low-voltage complete switch equipment to use in former design at present.Alternate distribution for two 1/2 unit drawers of individual layer all is that the every utmost point phase line of turnover line all needs to be transferred to right side drawer by the drawer on the left side with the wire laying mode switching of individual layer plane.Be A, B, C three corresponding A, B, the C three-phases that are transferred to left side drawer of right side drawer, each three bus of turnover link to each other, and in one plane switching has increased the wiring area on short transverse.Also can increase for the connection of the copper busbar of 100A and following use turnover line length is corresponding, the copper material waste is bigger.And the six roots of sensation bus of plane routing connects up at grade, taken most of height space, thereby, as adding protection N line, three-phase and four-line can't be realized in life size 175 height.，
2, metal shell structure 1/2 unit drawer circuit distribution adapter (hereinafter to be referred as adapter), this structural shape adapter is used for GCK type low-voltage complete switch equipment and economical MNS and GCS type cabinet, and its width and height dimension are with moulding the shell structure adapter.Because the metal structure adapter need guarantee enough electric clearances and insulation distance, and patch the degree of depth, its gauge is increased to 85 millimeters by 45 millimeters that mould shell structure, like this for 1/2 little unit drawer of spatial volume, uses deep space to reduce.It also with mould that the shell structure adapter is the same can only accomplish three-phase switching, three-phase and four-line just more not have the possibility of realization.
Figure 20-22 is the existing structural representation that is arranged on the bus box of circuit distribution adapter inside, this bus box adopts individual layer plane formula wires design, be specially: this bus box comprises first limiting plate 23 ' of insulation, second limiting plate 24 ' of insulation, inlet wire copper busbar 20 ' and outlet copper busbar 19 ', described first limiting plate 23 ' is provided with three outlet bus ducts 25 ', three inlet wire bus ducts 251 ', 26 ' and three inlet wire bus outlet 27 ' of three outlet bus outlets, described second limiting plate 24 ' is provided with inlet wire plug cover 30 ', described inlet wire copper busbar 20 ' is provided with inlet wire inserted sheet 291 ', and described first limiting plate 23 ' and second limiting plate 24 ' fasten mutually and form cavity.The inlet wire copper busbar 20 ' and the outlet copper busbar 19 ' of this bus box are distributed on first limiting plate 23 ' of insulation, in order to guarantee the electric clearance between inlet wire copper busbar 20 ' and the outlet copper busbar 19 ', existing first limiting plate 23 ' can't increase outlet bus duct 25 ' and inlet wire bus duct 251 ' again, to realize the wire laying mode of three-phase and four-line.
Plate is an integrative-structure behind the two sides of the metal structure shell of existing in addition circuit distribution adapter and the metal shell, be the ∪ shape, sheet material for 540-550 millimeter width uses, must guarantee that certain thickness could guarantee that it patches the requirement of intensity, increased cost, and in half-finished storage and transportation process, take, increased the storage cost of transportation than large space.
Now be used for 1/2 unit drawer in cable and outlet copper busbar and/or inlet wire copper busbar connected mode such as Figure 20 and shown in Figure 22 of circuit distribution adapter: outlet copper busbar leading-out terminal and drawer turnover line inserted sheet 29 ' is pegged graft, be sleeved in the drawer inlet wire socket after outlet copper busbar leading-out terminal and drawer turnover line inserted sheet 29 ' are pegged graft, drawer inlet wire socket is arranged on the metal structure shell of circuit distribution adapter.Inlet wire copper busbar leading-out terminal and drawer turnover line inserted sheet 29 ' are pegged graft, and are sleeved in the drawer outlet socket after inlet wire copper busbar leading-out terminal and drawer turnover line inserted sheet 29 ' are pegged graft, and drawer inlet wire socket is arranged on the metal structure shell of circuit distribution adapter.The lug plate 48 that is connected with the cable of circuit distribution adapter 1/2 unit drawer during use is plugged on the mounting portion 15 ' of drawer turnover line inserted sheet 29 '.Because outlet copper busbar leading-out terminal and inlet wire copper busbar leading-out terminal need pass in and out line inserted sheet 29 ' with drawer and peg graft and be inserted in as a whole in the drawer inlet wire socket and drawer outlet socket on the metal structure shell that is arranged on the circuit distribution adapter, but not outlet copper busbar leading-out terminal and inlet wire copper busbar leading-out terminal are directly stretched out the metal structure shell of circuit distribution adapter, thereby increased the thickness space of circuit distribution adapter, shortened the deep space of 1/2 unit drawer; Outlet copper busbar and/or inlet wire copper busbar connect with lug plate 48 by drawer turnover line inserted sheet 29 ' in the above-mentioned in addition connected mode, form movable contact between turnover line copper busbar and the drawer turnover line inserted sheet 29 ', also form movable contact between drawer turnover line inserted sheet 29 ' and the lug plate 48, the movable contact temperature rise is higher in the use, and reliability is also poor than fixed contact.
