Technical field

The utility model relates to photo-voltaic power generation station infrastructure technique fields, specifically provide a kind of applied to photovoltaic plant Photovoltaic module intert wiring construction.

Background technique

The component string connection type of existing photo-voltaic power generation station be all each group of string is divided two rows be vertically arranged or it is upper, In, lower three row's lateral arrangements, component successively accesses in inverter system after annular concatenation, and this connection can only utilize 9 points of the morning To 3 period power generations in afternoon, the luminous energy of remaining time, which is unable to get, to be made full use of, and the waste of resource is caused.Therefore, it more fills The utilization resource and reasonable line arrangement divided, become people's urgent problem to be solved.

Utility model content

In order to solve the above-mentioned technical problem, it is interspersed to provide a kind of photovoltaic module applied to photovoltaic plant for the utility model Wiring construction, on the one hand makes full use of illumination resource, the PVF-1 type private cable in addition making full use of photovoltaic module included, most Construction investment is reduced in big degree, is reduced difficulty of construction, is shortened the construction period.

The utility model is realized in this way a kind of photovoltaic module applied to photovoltaic plant interts wiring construction, setting Multiple rows of photovoltaic module, photovoltaic module in every row is sequentially close to rack-mount, when the number of photovoltaic modules of every row is odd number When a, the cathode of the 1st photovoltaic module connects the anode of the 3rd photovoltaic module, and the cathode of the 3rd photovoltaic module connects the 5th photovoltaic The anode of component so repeats, until the cathode of the 2n-1 photovoltaic module connects the anode of the 2n+1 photovoltaic module；2n+1 The cathode of photovoltaic module connects the anode of the 2n photovoltaic module, and the cathode of 2n photovoltaic module connects the 2n-2 photovoltaic module Anode so repeats, until the cathode of the 4th photovoltaic module connects the anode of the 2nd photovoltaic module, the 1st photovoltaic module is just The cathode of pole and the 2nd photovoltaic module is separately connected cable, and cable is along installation with hanger to inverter；

When the number of photovoltaic modules of every row is even number, it is with every row's number of photovoltaic modules for the difference of odd number, The cathode of the 2n-1 photovoltaic module connects the anode of the 2n+1 photovoltaic module, and the cathode of the 2n+1 photovoltaic module meets 2n+2 The cathode of the anode of a photovoltaic module, the 2n+2 photovoltaic module connects the anode of the 2n photovoltaic module.

Further, 2 row's photovoltaic modulies are set on bracket, and 2 row's photovoltaic modulies are respectively connected to the different tracking of inverter In circuit, and n=10.

Further, the cable is the PVF-1 type private cable that photovoltaic module carries.

Compared with the prior art, the advantages of the utility model are: illumination is on the one hand made full use of, it is on the other hand sufficiently sharp With the length for the private cable that photovoltaic module carries, compared to the usual manner of adjacent component wiring, interspersed mode of connection can To save about 50% later period cable dosage.

Detailed description of the invention

With reference to the accompanying drawing and embodiment is described in further detail the utility model:

Fig. 1 is that two rows of photovoltaic modulies are arranged on bracket, and sheet is practical when every row is odd number photovoltaic module and n=10 Novel structural schematic diagram；

Fig. 2 is that two rows of photovoltaic modulies are arranged on bracket, and sheet is practical when every row is even number photovoltaic module and n=10 Novel structural schematic diagram.

Specific embodiment

In order to make the purpose of the utility model, technical solutions and advantages more clearly understood, with reference to the accompanying drawing and implement Example, the present invention will be further described in detail.It should be appreciated that specific embodiment described herein is used only for explaining The utility model is not used to limit the utility model.

With reference to Fig. 1, the utility model provides a kind of interspersed wiring construction of the photovoltaic module applied to photovoltaic plant, setting 2 Photovoltaic module is arranged, is called #1 string and #2 string respectively, the photovoltaic module in every row is sequentially close to rack-mount, the photovoltaic of every row Number of components is 21, is successively discharged to #21 from #1, and the cathode of the 1st photovoltaic module connects the anode of the 3rd photovoltaic module, the 3rd The cathode of photovoltaic module connects the anode of the 5th photovoltaic module, so repeats, until the cathode of the 19th photovoltaic module connects the 21st light Lie prostrate the anode of component；The cathode of 21st photovoltaic module connects the anode of the 20th photovoltaic module, the cathode of the 20th photovoltaic module The anode of the 18th photovoltaic module is connect, is so repeated, until the cathode of the 4th photovoltaic module connects the anode of the 2nd photovoltaic module, The cathode of the anode and the 2nd photovoltaic module of 1st photovoltaic module is separately connected cable, and cable is along installation with hanger to inverter；

With reference to Fig. 2, the number of photovoltaic modules of every row is 22, and the difference for being 21 with every row's number of photovoltaic modules is, The cathode of 19th photovoltaic module connects the anode of the 21st photovoltaic module, and the cathode of the 21st photovoltaic module connects the 22nd photovoltaic group The anode of part, the cathode of the 22nd photovoltaic module connect the anode of the 20th photovoltaic module.

The cable is the PVF-1 type private cable that photovoltaic module carries.

The photovoltaic group string of two adjacent positions is grouped, such as in flat land by the utility model according to illumination particularity The component of area's arrangement, can divide according to upper and lower structures, as shown in Figure 1, due to lower layer's group string sunrise at 9 points in the morning it Between, easily blocked by the other assemblies that south orientation is arranged, therefore upper layer be divided into #1 group in the at 3 points in afternoon to the time content between sunset String, lower layer are divided into #2 group string, are respectively connected in the different tracking loops of inverter.This packet mode can make #1 group go here and there It still can be unaffected with normal power generation during #2 group string is blocked；If it is on mountainous region or the ground for thering is protrusion to block Area arranges photovoltaic module, then should draw packet chain according to the position for blocking shade, the component not blocked divide #1 group into and go here and there, and have and block Component divides #2 group string into, equally, then two groups of strings is respectively connected in the different tracking loops of inverter.Its purpose is also for subtracting Be blocked a group influence of the string to whole generated energy less.It, can also be with same when system is upper, middle and lower-ranking lateral arrangement Group forming criterion, and illumination particularity is combined to be grouped to photovoltaic module.
