Fig. 7 shows the schematic diagram of an embodiment of the first distribution group provided by the invention, as shown in Figure 7, this distribution group 7 comprises that at least two power distribution cabinets 71 form, and in Fig. 7, especially to comprise that two power distribution cabinets describe as example, the present invention is not as limit.
Between at least one pair of adjacent power distribution cabinet, be provided with the shared cable passage of this adjacent power distribution cabinet.In practice, the form of such cable passage can have a variety of, for example, can be, between this adjacent power distribution cabinet, cable passage cabinet is set, and this cable passage cabinet has formed cable passage.Take Fig. 7 as example, between two power distribution cabinets 71, be provided with shared cable passage cabinet 73.The cabinet space of this cabinet 73 is limited and is formed by the power distribution cabinet 71 of both sides and Qianmen, back door.
In the prior art in order to leave space to cable, need to cable passage be set separately at each power distribution cabinet, this makes the volume of power distribution cabinet excessive, and in the present embodiment, between adjacent power distribution cabinet 71, be provided with shared cable passage, this has improved the utilance of cable passage, and reduced the volume of single power distribution cabinet, therefore the volume of whole distribution group is reduced.
In addition, occur also very convenient by shared cable passage for adjacent power distribution cabinet.
Embodiment tri-
Fig. 8 shows the schematic diagram of another embodiment of the first distribution group provided by the invention, as shown in Figure 8, is mainly: for the optimal design of bus-bar room position in this distribution group 7 ' from the different of distribution group 7 in embodiment mono-.
In common power distribution cabinet, bus-bar room is arranged near the top of cabinet, and the equipment such as circuit breaker are all arranged on the below of bus-bar room, bus need to be guided to each equipment of below from bus-bar room always, this makes the use amount of bus larger, and the cost of actual median generatrix is also higher, therefore cause whole power distribution cabinet cost occupy over-evaluate under.
The present embodiment is a kind of prioritization scheme proposing after the problems referred to above considering.Refer to Fig. 8, this distribution group 7 ' has comprised at least two power distribution cabinets 71 ', between adjacent two power distribution cabinets 71 ', is provided with shared cable passage cabinet 73 '.
Power distribution cabinet 71 ' comprises cabinet, and the middle part of the height of cabinet is provided with bus-bar room 741, and circuit breaker 742,743 in power distribution cabinet 71 ' is arranged on the upper and lower of cabinet, is also arranged on the upper and lower of bus-bar room 741.Like this, the bus of drawing from bus-bar room 741 can extend respectively up and down, and use amount that can direct saving bus solves the cost of whole power distribution cabinet.
Two power distribution cabinets that above-mentioned the first distribution group is adjacent and the cable passage being arranged between adjacent two power distribution cabinets can share an integrated top.
Embodiment tetra-
Fig. 4 shows the schematic diagram of an embodiment of the second distribution group provided by the invention, this distribution group comprises at least two the first distribution groups 41,42, the concrete structure of this first distribution group is shown in above-described embodiment two or three, specifically, referring to Fig. 7,8, each the first distribution group comprises the power distribution cabinet described at least two embodiment mono-.And between at least one pair of adjacent power distribution cabinet, be provided with the shared cable passage of adjacent power distribution cabinet in each the first distribution group.The concrete structure of two the first distribution groups 41,42 can be the same or different.
In Fig. 4, the each several part in the first distribution group shares an integrated top.
In the second distribution group shown in Figure 4, also consider the waterproof problem in the gap of (actual is two adjacent power distribution cabinets of two the first distribution groups) between adjacent two the first distribution groups, therefore one preferred embodiment in, above the gap of the first distribution group 41,42, be provided with waterproof construction 3, this waterproof construction 3 is for carrying out water-proofing treatment to the gap between the first distribution group 41,42.Particularly, this waterproof construction 3 comprises the overlay 31 of strip, the upwardly extending barrier rib 32 in both sides (being shown label 31a and 31b Fig. 4) and barrier rib 33 from overlay 31.In the present embodiment, barrier rib 32 and barrier rib 33 are perpendicular to the rectangle of overlay 31 rectangular, and the rectangular preferred length of this rectangle is not less than the length of overlay 31.
Relative position relation between waterproof construction 3 and the first distribution group 41,42 is such: the length direction of overlay 31 is parallel with the gap bearing of trend between the first distribution group 41,42, and overlay 31 covers the gap between the first adjacent distribution group 41,42.
Like this, end and two barrier ribs 32 and 33 by overlay 31 length directions limit discharge outlet, the water flowing down from top can enter in the space of overlay and barrier rib restriction, and flows down by this discharge outlet, prevents from flowing in the gap between adjacent power distribution cabinet; In addition, overlay also can prevent that the water at adjacent two power distribution cabinet tops from flowing in the gap between power distribution cabinet.
Embodiment five
Fig. 5 shows the schematic diagram of another embodiment of the second distribution group provided by the invention, and the parts that in Fig. 5, label is identical with label in Fig. 4 are identical structure, repeat no more here.The present embodiment is mainly from the different of distribution group shown in Fig. 4: the concrete structure difference of waterproof construction 3 '.As shown in Figure 5, the waterproof construction 3 ' in the present embodiment comprise the overlay 31 ' of strip, upwardly extending barrier rib 32 ' and barrier rib 33 ' from the both sides (being shown label 31a ' and 31b ' Fig. 5) of overlay 31 '.It is rectangular that barrier rib 32 ' and barrier rib 33 ' are outward-dipping and aduncate cambered surface, and " outward " here refers to that " interior " here refers to towards two directions that barrier rib 32 ' is relative with 33 '.
Similarly, relative position relation between waterproof construction 3 ' and the first distribution group 41,42 is such: the length direction of overlay 31 ' is parallel with the gap bearing of trend between the first distribution group 41,42, and overlay 31 ' covers the gap between the first adjacent distribution group 41,42.
Can make equally the water flowing down from top can enter in the space of overlay and barrier rib restriction by the present embodiment, and flow down by this discharge outlet, prevent from flowing in the gap between adjacent power distribution cabinet; In addition, overlay also can prevent that the water at adjacent two power distribution cabinet tops from flowing in the gap between power distribution cabinet.
