Abstract
The utility model discloses a photovoltaic intelligence alternating current -direct current collection flow box, orientation about the little current breaker mode of arranging is in the alternating current -direct current collection flow box, the big current breaker mode of arranging is upper and lower orientation, and the output of little circuit breaker is connected to the short busbar of many mounting holes by the patchcord, installs big current breaker's input according to the order after many mounting holes weak point busbar makes up again. The utility model discloses compact structure, simple to operate has avoided the copper bar to connect big, the with high costs problem of volume.
Description
Technical field
This utility model relates to exchange header box in a kind of photovoltaic generating system.
Background technology
At present, exchanging header box and adopt the arrangement of various chopper above-below directions, conflux mode with copper bar in photovoltaic generating system, the shortcoming of which is that volume is big, and cost is high.
Summary of the invention
The purpose of this utility model is to provide a kind of photovoltaic intelligent alternating current-direct current header box, and compact conformation, volume is little, easy for installation, and cost is low.
The technical solution of the utility model is: a kind of photovoltaic intelligent alternating current-direct current header box, it is characterized in that: in alternating current-direct current header box, minimum circuit breaker arrangement mode is left and right directions, heavy current breaker arrangement mode is above-below direction, the output of little chopper is connected to the short bus-bar of many installing holes by flexible cord, and the short bus-bar of many installing holes is installed to the input of heavy current breaker again after combining in order.
Wherein the short bus-bar of many installing holes is double-deck or three layers.
The beneficial effects of the utility model are, compact conformation is easy for installation, it is to avoid it is big that copper bar connects volume, the problem that cost is high.
Accompanying drawing explanation
Fig. 1 is layout of the present utility model (7 converge 1).
Fig. 2 is one of short bus-bar schematic diagram of many installing holes.
Fig. 3 is the two of the short bus-bar schematic diagram of many installing holes.
Fig. 4 is the short bus-bar schematic diagram of the many installing holes of three layers.
Fig. 5 is the short bus-bar schematic diagram of double-deck many installing holes.
Detailed description of the invention
Below in conjunction with drawings and Examples, this utility model is further illustrated.
In FIG, connect each chopper with flexible cord, the short bus-bar 1 of many installing holes of an individually designed bilayer or three layers.
Multichannel (such as 7 tunnels) photovoltaic group string formula inverter inputs many group three-phase alternating currents respectively to the minimum circuit breaker exchanging the multiple left and right directions layout of header box.
The output of little chopper is connected to the short bus-bar of many installing holes such as Fig. 2 or Fig. 3 by flexible cord.
The short bus-bar of many installing holes 1 of Fig. 2 and Fig. 3 is combined into the three layers as shown in Fig. 4 and Fig. 5 or the double-deck short bus-bar of many installing holes.
Three layers or the short bus-bar 1 of double-deck many installing holes are installed to the input of heavy current breaker again after combining in order.Exported by the outfan of last heavy current breaker.
Outer profile size after three layers or the combination of double-deck many installing holes short bus-bar 1 should be effectively isolated in scope at insulating barrier, it is to avoid separately does insulation processing.
If mounting base is metallic plate it should be noted that Insulation Problems.
The short bus-bar of many installing holes 1 recommends the tin plating process of red copper, and its sectional dimension, except meeting mechanical erection requirement, also should meet electric current current-carrying requirement, it is recommended that its sectional dimension is chosen by the upper limit in handbook.
