Present invention is described according to following accompanying drawing in addition.
Fig. 1 is the cable access device that is used for bus system with housing, and
Fig. 2 has at least one electrical interface that is used for cable and at least one cable access device that is used for bus system for the electrical interface of bus-bar.
Embodiment
Figure 1 illustrates the cable access device 100 for bus system.This cable access device 100 comprises the electrical interface 401,402,403,404 for each cable; 411; 421 and the electrical interface 201,202,203,204,205,206,207 that is used for each bus-bar; 301,302,303.In the inside of cable access device 100, the electrical interface that is used for cable is electrically connected with the electrical interface that is used for bus-bar.
Cable access device 100 comprises housing 500, has settled the electrical interface 401,402,403,404 that is used for cable at this housing; 411; 421 and the electrical interface 201,202,203,204,205,206,207 that is used for bus-bar; 301,302,303.This housing 500 is formed by the side 501,502,503 shown in Fig. 1.According to the view of Fig. 1, the side 501 of described housing 500 is provided with the ventilation line of rabbet joint.The ventilation line of rabbet joint can be arranged on other side 502,503 equally.
The electrical interface that is used for cable and bus-bar is placed in the side 502 of housing 500 according to Fig. 1.Described side 502 be described square housing 500 have the side of minimum area with respect to other two sides 501,503.
According to the view of Fig. 1, be used for the electrical interface 401,402,403,404 of cable; 411; 421 with the electrical interface 201,202,203,204,205,206,207 that is used for bus-bar; 301,302,303 be placed on the same side 502 of square housing 500.Can consider equally will be for the electrical interface 401,402,403,404 of cable; 411; 421 with the electrical interface 201,202,203,204,205,206,207 that is used for bus-bar; 301,302,303 be placed on the side of opposed layout of square housing 500.
If will be placed on the wind energy plant by cable access device 100 of the present invention, under pointing to together with interface in described side 502 under the state that assembles so.This means at the inner bus-bar that guides of the pylon of wind energy plant and for example can be electrically connected with cable access device 100 by the bolt connection.Guiding is by electrical interface 401,402,403,404; 411; Under 421 cable points in it is implemented equally.This is particularly advantageous, because for example moisture can not enter the inside of cable access device 100 along cable.Also advantageously, if the cable that is connected with cable access device 100 can directly import in the pylon head of wind energy plant and needn't pass through transfer (for example slewing rollers) channeling conduct on described interface points to the time.
Figure 2 illustrates cable access device 100, and it there is not housing 500.In Fig. 2, exemplarily show guiding by the cable 921 of electrical interface 421.This cable 921 imports the inside of cable access device 100 and goes up at contact position 707 ' there and is electrically connected with bus-bar 207.Bus-bar 207 is guided again by cable access device 100 and on its side 502 and is stretched out from cable access device 100.On the end of the hook construction of bus-bar 207, for example can connect outside bus system by bolt.
Cable access device 100 comprises the support plate 592 at the right angle support arm 593 shown in Fig. 2 of having of U-shaped bending.Settling bearing 561,562,563,564,565,566 at support plate.Crossbeam 551,552,553 is used for stablizing housing 500.Can settle the support that is used for cable at crossbeam extraly.Described cable 921 for example remains on the crossbeam 551 by support 591.Described support plate 592 can be configured to be different from other favourable shape of U-shaped equally.
Pillar 581,582 is used for stationary housing 500.This housing 500 can be inserted on the described pillar 581,582 and by means of being threaded or riveting to prevent that housing 500 and cable access device 100 from unclamping by corresponding notch.
The support plate 592 of described U-shaped bending comprises for bus-bar 201,202,203,204,205,206,207; 301,302,303 support.Described bus-bar comprises the projection of side, has settled the contact point that is used for cable in described projection.Described bus-bar 303 for example comprise have contact point 603,603 ', 603 ' ' projection.Bus-bar 302 comprises and has contact point 602,602 ' projection.Bus-bar 207 comprise have contact point 707,707 ', 707 ' ' projection.On bus-bar, can settle a plurality of contact points for cable, make a plurality of cables to be placed on the bus-bar with littler cross section.This uses to such an extent that cost is more cheap than the cable with corresponding bigger cross section.In addition, cable should be able to carry out certain bending equally, and this can't carry out in the cable with very big cross section.
Can freely select the number of cables of each bus-bar, for example can use two, three or four cables and be electrically connected on the bus-bar for each bus-bar.
Cable access device 100 can comprise the electrical interface for the polytype bus-bar.According to Fig. 2, this cable access device comprises first electrical interface 202 for first bus-bar, 203,204,205,206,207 and second electrical interface 301,302,303 that is used for second bus-bar.The electrical interface that is used for first bus-bar is constructed with first cross section and is constructed with second cross section for the electrical interface of second bus-bar.This first cross section can be different with second cross section.The quantity of first bus-bar and second bus-bar equally can be different mutually.According to Fig. 2, for example described cable access device 100 can comprise seven first bus-bars and three second bus-bars.
The electrical interface 401,402,404 that is used for cable; 411; 421 can be the through hole by housing side 502.This through hole can import cable the inside of housing, and cable is electrically connected with the electrical interface that is used for bus-bar there.For example figure 2 illustrates cable 921, this cable imports the inside of housing 500 and goes up at contact position 707 ' there by through hole 421 and is electrically connected with bus-bar 207.Described through hole can be configured to cable sleeve, and this cable sleeve so surrounds described cable, thereby for example can not allow foul or moisture enter the inside of cable access device 100.
When using by cable access device 100 of the present invention in wind energy plant, the shape of elongation vertically of access device is favourable because provide hardly in the inside of wind energy plant the space and therefore the cable access device radially do not allow volume very big.The quantity that is used for the interface of bus-bar has been determined the axial length by cable access device 100 of the present invention.Make the expansion of external dimensions of cable access device 100 radially minimize and utilize the length that exists anyway of bus-bar as connection space thus.
Position is radially saved in the space that advantageously exists by the system orientation of using vertically by cable access device 100 of the present invention.Simplified the order of connection of the system that is used for having plural bus-bar or phase by cable access device 100 of the present invention.Additionally can settle the side 502 of interface to point to down by on its of described square housing 500, save platform or transfer for cable.
