Description
Technical field
The present invention relates to the dedicated devices in a kind of low-voltage complete switch equipment, the bus box that is specifically related to a kind of 100A and the following multilayer wiring of using for medium and small electric current 1/2 unit drawer of draw out switchgear MCC cabinet, the invention still further relates to the circuit distribution adapter that this bus box is housed.
Background technology
According to Electrical Appliances Designing requirement, circuit distribution adapter has three-phase or three-phase and four-line two classes, has A, B, C three-phase and A, B, C, two kinds of wirings of N three-phase and four-line in circuit distribution adapter.A line of the circuit distribution adapter of existing little electric current 1/2 unit drawer all adopts individual layer plane formula wires design, and the circuit distribution adapter of using is at present 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 of version only has domestic GCS type extraction type low voltage switch apparatus set and the MNS of ABB AB type extraction type low voltage switch apparatus set to use in former design at present.Alternate distribution for two 1/2 unit drawers of individual layer is all that the every utmost point phase line of line all need be transferred to by the drawer on the left side right side drawer with the switching of individual layer plane wire laying mode.Be corresponding A, B, the C three-phase that is transferred to left side drawer of A, B, C tri-of right side drawer, each three buses of turnover are connected, and in one plane switching has increased wiring area in short transverse.For the connection of the copper busbar line length of 100A and following use is corresponding, also can increase, copper material waste is larger.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 cannot 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 for GCK type low-voltage complete switch equipment and economical MNS and GCS type cabinet, and its width and height dimension are with moulding shell structure adapter.Because metal structure adapter need to ensure 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 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 are 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 the first limiting plate 23 ' of insulation, the second limiting plate 24 ' of insulation, inlet wire copper busbar 20 ' and outlet copper busbar 19 ', described the first limiting plate 23 ' is provided with three outlet bus grooves 25 ', three inlet wire bus ducts 251 ', 26 ' and three inlet wire bus outlet 27 ' of three outlet bus outlets, described the second limiting plate 24 ' is provided with incoming line plug cover 30 ', described inlet wire copper busbar 20 ' is provided with inlet wire inserted sheet 291 ', described the first limiting plate 23 ' and the second limiting plate 24 ' mutually fasten and form cavity.Inlet wire copper busbar 20 ' and the outlet copper busbar 19 ' of this bus box are distributed on the first limiting plate 23 ' of insulation, in order to guarantee the electric clearance between inlet wire copper busbar 20 ' and outlet copper busbar 19 ', existing the first limiting plate 23 ' cannot increase outlet bus groove 25 ' and inlet wire bus duct 251 ' again, to realize the wire laying mode of three-phase and four-line.
After the two sides of the metal structure shell of existing circuit distribution adapter and metal shell, plate is integrative-structure in addition, be ∪ shape, sheet material for 540-550 millimeter width is used, it patches the requirement of intensity must to guarantee certain thickness guarantee, increased cost, and in half-finished storage and transportation process, take larger space, increased storage cost of transportation.
Now for 1/2 unit drawer in cable and the outlet copper busbar of circuit distribution adapter and/or inlet wire copper busbar connected mode as shown in Figure 20 and Figure 22: outlet copper busbar leading-out terminal and drawer line inserted sheet 29 ' are pegged graft, outlet copper busbar leading-out terminal and drawer line inserted sheet 29 ' are sleeved in drawer inlet wire socket after pegging graft, and drawer inlet wire socket is arranged on the metal structure shell of circuit distribution adapter.Inlet wire copper busbar leading-out terminal and drawer line inserted sheet 29 ' are pegged graft, and inlet wire copper busbar leading-out terminal and drawer line inserted sheet 29 ' are sleeved in drawer outlet socket after pegging graft, and drawer inlet wire socket is arranged on the metal structure shell of circuit distribution adapter.The lug plate 48 being connected with the cable of circuit distribution adapter 1/2 unit drawer during use is plugged on the mounting portion 15 ' of drawer line inserted sheet 29 '.Because outlet copper busbar leading-out terminal and inlet wire copper busbar leading-out terminal need to be pegged 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 circuit distribution adapter with drawer line inserted sheet 29 ', but not outlet copper busbar leading-out terminal and inlet wire copper busbar leading-out terminal are directly stretched out to 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; In addition in above-mentioned connected mode, outlet copper busbar and/or inlet wire copper busbar connect by drawer line inserted sheet 29 ' and lug plate 48, between line copper busbar and drawer line inserted sheet 29 ', form movable contact, between drawer line inserted sheet 29 ' and lug plate 48, also form movable contact, in use procedure, movable contact temperature rise is higher, and reliability is also poor than fixed contact.
