Abstract
The invention discloses a distribution box used for a photovoltaic power station. The distribution box comprises a distribution box body. A plurality of conflux boxes are arranged in the distribution box body. The conflux boxes are arranged into one column or several columns. Each column includes a plurality of conflux boxes which are parallel to each other. Orientations of anode terminals of the plurality of conflux boxes located at the same column are consistent. Orientations of cathode terminals of the plurality of conflux boxes located at the same column are consistent. The anode terminals of the conflux boxes are located at one side of the conflux boxes. The cathode terminals of the conflux boxes are located at a side opposite to the side where the anode terminals are located. By using the distribution box provided in the invention, wiring is convenient and simultaneously a probability of generating a short circuit between an anode and a cathode of each conflux box is greatly reduced, which is good for achieving work reliability of the distribution box used for the photovoltaic power station.

Greatly reduce the probability being short-circuited between each header box positive and negative electrode, be conducive to photo-voltaic power generation station distribution box work can
By property.
Further technical scheme is：
The reliability of for the benefit of this distribution box wiring, is provided with the positive terminal of each header box and negative terminals
Binding post.
As needed, easily appropriate number of header box is installed, also includes being arranged at distribution for ease of in distribution box
Installing rack on case body, described installing rack is in strip, and described header box is installed on installing rack, and each header box is being installed
Position on frame is adjustable.
As a kind of distribution box way of realization with safeguard function, described distribution box body is the casing being provided with case lid
Structure, described header box is installed on inside body structure.
The invention has the advantages that：
Described header box is used for being arranged on photovoltaic module with inverter as a converging component, can reduce DC side cable
Wiring quantity, improve the efficiency of system and reliability, also can facilitate system maintenance simultaneously.And during header box uses,
Due to direct-current arc not zero crossing, header box positive terminal of the prior art and negative terminals are all arranged at header box
Homonymy in order to wiring, so, under some factors (such as foreign matter entrance, moisture, cable impaired etc. factor), positive pole connects
When producing electric arc between line end and negative terminals, electric arc is difficult to extinguish, and easily causes chain reaction, causes whole distribution box
Burn.
In this programme, by will be arranged in rows between header box, and the positive terminal of each header box and negative terminal
Both ends, in being oppositely arranged, so, are equivalent to and have made the positive and negative mode of connection being arranged alternately in prior art into positive and negative electrode
The separate mode of connection, meanwhile, the equal concentrated setting of positive and negative electrode of each header box, so, not only easy-to-connect, also significantly simultaneously
Reduce the probability being short-circuited between each header box positive and negative electrode, be conducive to the reliability of photo-voltaic power generation station distribution box work.
