4, for skyscraper, if adopt cable power supply, then every layer of at least one cable leads to ground floor general supply control cubicle, and the cable laying trouble adopts the three-dimensional electric power system of dendroid of the present utility model, and then simple in structure, it is convenient to lay.

5, can the power various temporary electricities of tool and so on of starting building of standby current collector pick out power supply in moulding the shell bus duct, avoid patch.Avoid power supply-distribution system is revised.

6, slip pipe of the present utility model has the position of five conductive guides, and both applicable three-phase four-wire system is applicable to three-phase five-wire mode again.

7, change simple, the highly versatile of joint design of direction, reduced the mould of making parts, cost is low, is convenient to produce in batches.

Now in conjunction with the accompanying drawings:

Fig. 1 is the structural representation of a kind of embodiment of combination of the present utility model.

Fig. 2 is the A-A office parting view of Fig. 1.

Fig. 3 is that the utility model is used for the structural representation to the embodiment of the closed straight line power-feed section of permanent plant power supply.

The shell bus duct device of moulding of the present utility model, by straight line power-feed section (as Fig. 2, shown in Figure 3), the joint (as shown in Figure 1), switch-box and the installation accessories that change direction or current capacity are formed, the whole shell bus duct device of moulding generally is the three-dimensional distribution of dendroid in building, utilize various terminal to be branched to several one-level branch straight line power-feed sections by a dried straight line power-feed section, each one-level branch is branched into several secondary branches again, is branched to three grades of branches again by secondary branch ...The current capacity maximum of trunk, the current capacity of branch reduces step by step, has so just realized the distribution that supplies to any locus power consumption equipment in building.

The straight line power-feed section can have Fig. 2 and two kinds of structures shown in Figure 3, straight line power-feed section shown in Figure 2 is made up of slip pipe 3, cover plate 2 and current collector 1, it is that 91202971.4 the compound safety sliding contact line device of extruding is improved that structure adopts number of patent application, increased a cover plate 2, the shell opener of moulding of slip pipe 3 can be built, being used for only need be to the section of permanent plant power supply.When taking off cover plate 2, straight line power-feed section shown in Figure 1 promptly can be used for the power supply to mobile device, five conductive guides 4 and 5 are arranged in the plastic housing of slip pipe 3, equipment 7 during the bottom of current collector 1 is moved is stirred down same moved further through shift fork 8, the top of current collector 1 is contained in the slip pipe 3, and the brush 6 on the current collector 1 is slided on conductive guide 4 and 5 by spring compression.By total power distribution cabinet or power bus power supply is introduced conductive guide, on the brush 6 of current collector 1 and stub cable pass to electric current power consumption equipment 7 in moving, realized the equipment 7 in moving is powered incessantly, the motion track at equipment 7 centers is straight line or camber lines parallel with slip pipe 3, slip pipe 3 is that scale is a certain-length, so that production and transport, can utilize when mounted to connect folder 9 slip pipe 3 is longitudinally coupled together, satisfy the length requirement that uses. Conductive guide 4 and 5 termination are at outside lateral bending 90 degree of slip pipe two ends, and the boring back couples together conductive guide with bolt on the termination, and electric current is not interrupted, and is convenient to the junction of current collector 1 by adjacent two slip pipes again.

In the occasion that need not move power supply, in order to increase electric current and to be more suitable for moist or the use down of with serious pollution environment, adopt straight line power-feed section shown in Figure 3, by conductive guide 4 and 5 and the metal-back 14 of closed slip pipe 13 and band reinforcement form, this sealing structure and good insulation preformance, corrosion-resistant, but in order to satisfy the mechanical requirement that large span is installed, can outside slip pipe 13, put the metal-back 14 of band reinforcement, generally adopt aluminium alloy extrusions, can improve strength and stiffness.Three conductive guides 5 have bigger sectional area, be used to transmit 380 volts of voltages, the sectional area of two conductive guides 4 be conductive guide 5 half or 60%, be used to transmit 220 volts of voltages, it is bigger to have adapted in the three-way five-wire system 380 volts of electric currents like this, 220 volts of different power load requirements that electric current is less.When adopting three-phase four-wire system, the conductive guide 4 of a small bore can be made center line uses, mill out 5 parallel slotted holes from the upper surface of closed slip pipe 13, the top and a side of conductive guide 4 and 5 are exposed, distinguish corresponding contacts with conductive guide 4 with 5 and charged for the grafting reed of jack switch case, like this can be through the plug-in type switch-box directly to the power consumption equipment output current.

The joint of change direction shown in Figure 1 or current capacity inserts as parts by utilizing slip pipe 3 or 13 to be processed into short slip pipe 12 that case 10 forms, its inner conductive copper sleeve then fuses, when adopting 4 roots and tops is the short slip pipe 12 insertion cases 10 of 90 degree, just become four-way connection, when reducing by one or two short slip pipes 12 again, then become threeway or quarter bend, not putting short slip pipe 12 places builds with lid 11, Figure 2 shows that a three-way connection, every kind of four-way, threeway or quarter bend all divide level and vertical two classes, so that up and down to any spatial spread, it is long-pending that the varying capacity joint then is reduced to the larger sectional area of conductive guide small cross sections, make on the conductive guide electric current from large to small, guarantee the economy of electric power system.
