Detailed description of the invention
Further illustrate technical scheme of the present invention below in conjunction with accompanying drawing and by detailed description of the invention.
Fig. 1 is that the standard type MNS low pressure draw-out type of the half function plate that provides of the specific embodiment of the invention is openedClose the structural representation of cabinet. As shown in Figure 1, the standard type MNS low pressure draw-out type of this half function plate is openedThe frame structure of closing cabinet is identical with the switch cabinet of standard, adopts C type section bar to assembly, and assembling is simpleFast, framework is firmly attractive in appearance. The standard type MNS low voltage drawing-out switching carbinet body of half function plate comprise cabinet,Be fixed on multiple interlayer boards of the inside of cabinet, between adjacent two-layer interlayer board, be provided with one or more drawers,Cabinet is surrounded by crossbeam, longeron and column, and crossbeam, longeron and column are vertical between two, forms oneThe cabinet of rectangle.
The standard type MNS low voltage drawing-out switching carbinet body of half function plate comprises wire inlet unit 1, outgoing line unit.Fig. 2 is the structural representation of the wire inlet unit that provides of the specific embodiment of the invention. As depicted in figs. 1 and 2,Described wire inlet unit 1 comprises that half function plate 11, bus-bar sleeve plate and several are positioned at described half block meritThe L-type vertical row 12 of energy plate 11 front portions, described half function plate 11 rear portions are provided with leading-in box 13, inlet wireIn box 13, copper sheathing is housed, copper sheathing contacts and is connected with L-type vertical row 12; Bus-bar sleeve plate covers L-typeVertical row, leaving can be for the interface of inlet wire inserted sheet turnover. The quantity of described leading-in box 13 is vertical with L-typeRow 12 quantity is identical. In the present embodiment, described copper sheathing is vertical shape.
Further, crossbeam comprises interior crossbeam 3, and interior crossbeam 3 is positioned at the inside of cabinet, half function plate 11Be fixedly connected with interior crossbeam 3, half function plate 11 has good insulating properties, can effectively prevent from drawing because of faultThe arcing rising, avoids copper sheathing to shock by electricity to maintenance personal or operating personnel.
In the present embodiment, can contact easily described leading-in box with L-type vertical row for the ease of copper sheathingOn 13, be provided with the entrance hole 131 of vertical configuration, described entrance hole extends to L-type and hangs down from the upper surface of leading-in boxIn line place. Described copper sheathing is positioned at described entrance hole 131.
In the present embodiment, because wire inlet unit comprises half function plate and combines with half function plate and positionIn several L-type vertical row of half function prelaminar part, described half function plate 11 adopts high strength, high resistantCombustion engineering plastics thermoplastic shaping. The standard type MNS low voltage drawing-out switching carbinet body of described half function plate is relativeThan global function plate standard type MNS, cost is more economized, and wire is the half of standard type, vertical channel costMore economize. And this cabinet has good isolation effect, can effectively intercept switch element failed shorted and produceThe impact of raw arcing on adjacent cells, guarantees that out of order unit accident can not cause adjacent function unitRelated accident, ensures that the power supply of miscellaneous equipment is stable, reduces loss.
In the present embodiment, because copper sheathing is enclosed in half function plate 11, therefore, in the time that drawer is extracted out,Copper sheathing can not expose.
As preferred version, described half function plate 11 is spliced by several assemblies, and each assembly comprisesConnecting plate 111 and be arranged on the side shield 112 of connecting plate 111 1 sides. Because half function plate 11 is adoptedForm with identical multiple parts assemblies, only need the assembling of actual requirement quantity, so installation is very squareJust. In the present embodiment, described half function plate 11 is spliced by 3 assemblies, in order to facilitate half block meritEnergy plate 11 is connected with other assembly, and the left side of the Far Left assembly of composition half function plate 11 is connected with a left sideGripper shoe 113, the right of rightmost assembly is connected with right support plate 114, left support plate 113 and right support plate114 are fixedly connected with other assembly of switch cabinet respectively, and half function plate 11 is stabilized. Described L-typeThe quantity of vertical row 12 and leading-in box 13 is corresponding with the number of assembly that is spliced into half function plate 11.
Certainly, the assembly of composition half function plate 11 is not limited to 3, can also establish according to actual needsBe set to 2,4,5 or other value. Equally, the quantity of described L-type vertical row 12 and leading-in box 13Corresponding with the number of assembly that is spliced into half function plate 11.
In the present embodiment, in order to make leading-in box 13 more stable with being connected of half function plate 11, and justIn the installation of leading-in box 13, as preferred version, establish connecting plate 111 upper ends of described half function plate 11Be equipped with several grooves 115, described each leading-in box 13 is separately positioned in described groove 115.
In the present embodiment, as preferred version, described side shield 112 is by under a upper end-stopping plate and twoEnd-stopping plate composition. A sidewall of described overhead gage composition groove. In order to save material, described two lower endsBetween baffle plate, be provided with space.
In the present embodiment, the standard type MNS low voltage drawing-out switching carbinet body of described half function plate also comprisesOutgoing line unit 2, described outgoing line unit 2 can be provided with rear outlet and side goes out line cable assembly, also can be independentBe provided with rear outlet or side and go out line cable assembly.
Certainly,, as another kind of preferred version, described outgoing line unit can also be provided with outlet plug-in unit. AsPreferred version, described outlet plug-in unit adopts a plug-in unit to add secondary inserting piece outlet.
Because outgoing line unit is provided with rear outlet and/or side goes out line cable assembly; Or outgoing line unit also can be establishedBe equipped with outlet plug-in unit. Outlet plug-in unit adopt an Eco-power plug-in unit as outlet plug-in unit than the cable of standard typeAssembly cost is more economized, and it is very convenient, flexible to install, and efficiency is also higher.
In the present embodiment, in order to facilitate the installation of end of incoming cables and leading-out terminal, in described cabinet, be provided with single insertingSheet wire.
