Description
Technical field
The utility model belongs to low-voltage cabinet technical field, relates to a kind of vertical bus system structure of low-voltage distribution cabinet.
Background technology
Low-voltage drawer type power distributing cabinet all has vertical bus, but the vertical bus of often kind of cabinet type is different.Low-voltage cabinet MNS is former is designed to low smoke halogen-free function template vertical bus, and it is L-type busbar; Domestic modified model is that bus clip is fixed on drawer laminate, installs busbar, installs steel plate and drawer unit separate with contact, and rear portion steel plate is converted into U-shaped and covers on bus and isolate outward.Analyze the vertical bus of above 2 kinds of structures, it cuts both ways.The first shortcoming is that cost is high, and current value is fixed, and cannot regulate, poor radiation.The size of its vertical bus is fixed, and the current value of its conduction is just fixing, for the power distribution cabinet of small area analysis, and some waste of vertical bus; For the power distribution cabinet of big current, bus current cannot meet the demands; And vertical bus mother is enclosed in feature board, insulate relatively good, but it is not all right to dispel the heat, as power distribution cabinet uses in the place that the temperature difference is larger, produce condensation, condensate, in vertical bus, cannot be evaporated the short time, affects its insulation property.The second vertical bus, fix with bus clip, vertical bus is round edge monolithic bus, and width size is selected according to current value size, but, be enclosed in the passage of steel, little to shell distance, insulation property are poor, and drawer contact insert port needs special isolation guard shield to separate, when drawer contact slap or loosening, the short circuit accident of busbar and steel dividing plate will be produced, affect the performance of power distribution cabinet; Or when falling into the foreign matter of any conduction in vertical bus, all can there is shorted to earth accident, although so the second vertical bus system overcomes the first shortcoming.Cost is low, and electric current is large, but failure rate increases.
Summary of the invention
Goal of the invention: in order to overcome the deficiencies in the prior art, the utility model provides a kind of low-voltage cabinet vertical bus system, reasonable in design, and install simple insulation property reliably, range conduction currents is wide, and intensity is high.
Technical scheme: for achieving the above object, the technical solution of the utility model is as follows:
A kind of low-voltage cabinet vertical bus system, comprise bus bar, busbar fixed support, inlet wire protective plate, bus clip and busbar isolating and protecting cover, on described busbar fixed support and inlet wire protective plate, under be disposed on bus bar vertical direction a straight line on, form busbar isolated grid plate, described busbar fixed support and bus clip match in opposite directions and arrange, described bus bar is arranged in the groove in opposite directions between busbar fixed support and bus clip, described busbar isolation guard shield is arranged on busbar isolated grid plate, described bus bar is between busbar isolation guard shield and busbar isolated grid plate.
Further, described groove is in opposite directions three.
Further, the guard shield of described busbar isolation guard shield to be cross section be U-shaped, comprise left side cover plate, shrouding and right side cover plate after bus, one side of described left side cover plate is integrated with a side of shrouding after bus to be connected, one side of described right side cover plate is integrated with another side of shrouding after bus to be connected, described left side cover plate is fixedly connected with busbar isolated grid plate with another side of right side cover plate, described bus bar, between busbar isolation guard shield and busbar isolated grid plate, prevents operation maintainer from encountering charged bus bar by mistake.
Further, after described bus, shrouding has contact busbar and observe square hole, on hole, card has transparent windows.
Further, described left side cover plate and right side cover plate have some long strip type louvres, and louvre width is less than 10mm, meets the requirement of degree of protection IP20, the heat that busbar line produces can be distributed simultaneously; Described inlet wire protective plate has the oblong aperture that width is less than 10mm, drawer contact can be inserted on vertical bus bar line by oblong aperture, connects conduction, and meets the requirement of degree of protection IP20, and the heat that busbar line produces can be distributed.
Beneficial effect: the utility model reasonable in design, install simple insulation property reliably, range conduction currents is wide, and intensity is high.
