Parts in accompanying drawing are labeled as: 1-the first rosette, 2-the second rosette, 3-the 3rd rosette, 4-the 4th rosette, 5-the 5th rosette, and 6-drags line, 7-rosette, 8-external dc cable, P-positive terminal port, N-negative terminal port.
Detailed description of the invention
Embodiment 1:
Rosette as shown in Figure 1 drags line length and novel component square array structure, including assembly square formation；Described assembly square formation its both positive and negative polarity two Wiring port P, N are electrically connected to inverter (not shown)；Described assembly square formation is made up of five rosettees 7；Described rosette 7 electrically connects by dragging line 6；Adjacent described rosette 7 is placed upside down with rosette 7 both positive and negative polarity Wiring port, it is placed upside down according to adjacent two rosette 7 both positive and negative polarity Wiring ports, connecting with the 4th rosette the 4, second rosette 2 according to the first rosette the 1, the 3rd rosette the 3, the 5th rosette 5 successively, row assembly square formation both positive and negative polarity two Wiring port P, a N is positioned over any one end of assembly square formation the most at last；Using the mode of connection of jumper connection, make both positive and negative polarity two Wiring port P, N of assembly square formation keep one end of assembly square formation in the case of outer ledger line, be effectively reduced the corresponding span of single component square formation drags line 6 long；7 positive terminal ports of multiple described rosettees are by dragging line 6 to electrically connect；Between multiple described rosettees, 7 negative terminal ports are by dragging line 6 to electrically connect.
Wherein, described assembly square formation its both positive and negative polarity two Wiring port P, N are arranged at any one end of assembly square formation, converge into inverter to facilitate, and effectively reduce additional AC line cable in traditional wired mode.
Rosette of the present utility model drags line length and the mode of connection of novel component square array structure, line length is dragged to add to 1000mm by original, adjacent two block assemblies are positive and negative reverse according to rosette, use the mode of connection of jumper connection, the positive and negative end mouth making assembly square formation keeps one end of square formation in the case of outer ledger line, is effectively reduced the line length of the corresponding span of single component square formation；Wherein, if rosette number is n, rosette drags line length=n*990mm+{(n-1) * 20mm}.
Embodiment described above is only to be described preferred implementation of the present utility model, is not defined spirit and scope of the present utility model.On the premise of without departing from this utility model design concept; various modification that the technical solution of the utility model is made by this area ordinary person and improvement; protection domain of the present utility model all should be dropped into, the technology contents that this utility model is claimed, all record in detail in the claims.
