Description
The utility model is a kind of low pressure combination draw out switchgear cabinet, belongs to the electric power system controller switching equipment.
At present, the drawer runner of the MNS draw out switchgear cabinet of external as Switzerland ABB AB production is the dove-tail aluminium section bar, and the drawer runner of Denmark DOMINO cabinet is the steel plate that bends, and the drawer runner of the up-to-date GCS drawout cubicle of domestic production is the bent plate that has bearing.All be to slide on the metal runners plane in the drawer bottom surface.This force of sliding friction is bigger, requires great effort very much during pulling.It is with the handle pull drawer on the drawer panel that the drawer of MNS, IOMINO cabinet advances, relatively require great effort, especially big drawer is more required great effort, and the propelling of the drawer of the GCS cabinet that latest domestic is produced is with pull drawers such as the handle on the drawer and arachnoid mechanism and gears, though operate more laborsaving, but mechanism is the complex operations inconvenience too, and above-mentioned domestic and international two kinds of products all do not have conversion position device.Be provided with 1/2 little drawer in MNS, the GCS cabinet and be provided with the bus boxcar, but design complicated, cost an arm and a leg and unreliable, especially auxiliary circuit patches switching device, easily dislocation when operation.And the DOMINO cabinet is not established the little drawer of 1/2M.Therefore, little current circuit also must occupy big drawer, thereby increases the design investment.The project plate of fixed vertical bus, horizontal bus, main circuit plug-in unit, auxiliary circuit plug-in unit is to adopt flame retardant type insulating material, the big mould compacting of employing to form in MNS, the GCS cabinet.Because mould is big, compression moulding is difficulty relatively, and rate of finished products is low, so cost an arm and a leg.
It is to adopt the embedded steel ball of shape groove that the purpose of this utility model provides a kind of drawer runner, makes drawer change rolling into from slip, and is provided with 1/2M bus boxcar, on the little drawer of 1/2M the handle propulsive mechanism is housed.Big drawer is provided with the technical practicality of rotation propulsive mechanism, cheap low pressure combination draw out switchgear cabinet.
The utility model is realized with following technical scheme: the rolling slideway 12 in low pressure cabinet 1 is that and arranged on left and right sides is equipped with pressing plate 18 and metal guide rail 17 respectively on drawer space bar 16, on pressing plate 18 He in metal guide rail 17 grooves, steel ball 19 is housed, drawer 2 or 3 or 4 or 5 base plate be contained on the steel ball 19 and metal guide rail 17 in.Rotation propulsive mechanism 14 is housed on big drawer 3,4,5.Rotation propulsive mechanism 14 is with cam 25, and bearing 26 is contained on the axle 31, and is by screw that 31 on cam 25 and axle is tight.One end face of cam 25 is provided with positioner, and cover 28 is contained in place, cam 25 band positioner one side end face, and steel ball 27, spring 29, holding screw 30 and cover 28 threaded engagement are housed in the cover 28, plays corrective action.Be contained in after the combinations such as axle 31, cover 28 on the part 24, a part 24 is contained in respectively on big drawer 3 or 4 or 5, and alignment pin 32 is contained on the drawer space bar 16.On big drawer 3,4,5 other ends plug connector 22 is housed, bus clip 20 is fixed on the space bar of central post 23, and vertical bus 21 is inserted on the bus clip 20.On the little drawer 2 of 1/2M, handle propulsive mechanism 10 is housed; Between vertical bus chamber 8 and the little drawer 2 of 1/2M, bus boxcar 7 is housed.Handle propulsive mechanism 10 is the end faces that handle 33 are contained in the little drawer 2 of 1/2M.Securing rod 37 is contained in the lock hole of handle, and trip lever 36, spring 34 are contained in the handle unlock hole, and button 35 is contained in spring 34 rear ends in the unlock hole.Support 38 is contained on the drawer space bar 16, on the cover 39 spring 40, jam plate 41 is housed; Cover 39 is contained on the support 38 by screw and nut.Plug 50 is housed on the other end of the little drawer 2 of 1/2M, inlet wire master plug-in unit 44 is housed on the bus box plate 48 of its adjacent bus boxcar 7, terminal board 45, secondary connector 46, feed out connection plug 47, vertical bus 21 is inserted on the inlet wire master plug-in unit 44, and bus assembled group component 49 is contained in the bus box 7, bus lid 42 is contained on the bus box plate 48 by screw, and protective cover 43 is contained on the bus lid 42.
The utility model compared with prior art has following outstanding advantage.
1, all slideway changes steel ball into by planar slide and rolls at the bottom of the drawer, reduces the frictional force between slideway and the drawer, and is free and relaxed when making the pull drawer, laborsaving, alleviates operator's labour intensity.
2, the handle propulsive mechanism is adopted in the push-and-pull of the little drawer of 1/2M, and rotary propulsive mechanism is adopted in the push-and-pull of 1M, 2M, the big drawer of 3M.Laborsaving when these two kinds of mechanisms can make the pull drawer, can guarantee again that three positions of connection, test, separation of drawer are located automatically, accurately and reliably.
3, a cover bus boxcar is housed between vertical bus chamber and the little drawer of 1/2M.No matter all adorn the little drawer of 1/2M like this in a cabinet, or the little drawer of 1/2M and 1M, 2M, 3M are big, and drawer loads in mixture, and only establishes a cover vertical bus chamber and get final product in same cabinet, and like this, same set of device can reduce cupboard quantity, the saving equipment expense.
4, it is indoor that vertical bus is arranged on the vertical bus of sealing, thereby drawer master plug-in unit and the vertical bus place of patching are provided with the fail safe that automatic guard mechanism has strengthened operation and power supply.
