Abstract
The invention discloses a split series solar junction box which comprises a base and a box body, wherein the base and the box body are connected and are made from heat conduction materials; multiple groups of terminal blocks are distributed in parallel between the base and the box body; and every two terminal blocks are connected through one or multiple diodes so as to perform a bypass protection function. Each terminal block is correspondingly connected with a bus bar on a solar component, and the terminal block and the diode are encapsulated by heat conductive adhesives. According to the junction box disclosed by the invention, the radiating effect of the junction box is enhanced, a solar photovoltaic cell component works more stably, and solar photovoltaic components with different power adopt the same junction boxes of three specifications, thereby being convenient in production and management.
Description
Technical field
The present invention relates to a kind of solar junction box, particularly a kind of solar junction box that adopts a plurality of splits to be connected in series.
Background technology
The terminal box of solar photovoltaic assembly all adopts terminal box connected mode of a block assembly at present, there are following two problems in this connected mode: the busbar of 1, guiding to terminal box in the assembly, and stube cable is oversize between the terminal box, its conductor resistance is big, loss is big, causes the power output of assembly to descend; 2, because only with a terminal box, the grouping of the battery sheet of solar photovoltaic assembly is few, because grouping causes every group voltage higher less.And there are following two problems in the terminal box that adopts this connected mode, 1, terminal box heat radiation is bad, directly influences the assembly operate as normal, 2, the assembly of different capacity uses different terminal boxes, various in stylely be unfavorable for management.
Adopt the split type mode that is connected in series then to overcome above-mentioned shortcoming, this connected mode has shortened the busbar of guiding to terminal box in the assembly, and the length of stube cable between the terminal box, reduced the decline of power output, owing to adopt the mode of a plurality of split type terminal box series connection, the battery sheet grouping of solar photovoltaic assembly can be divided into groups arbitrarily, and every group of voltage is reduced, and more helps the operate as normal of assembly.
Solar junction box of the present invention is specifically designed to the split type mode that is connected in series, and has the following advantages: 1, strengthened the heat radiation of terminal box, made solar photovoltaic battery component work more stable.2, terminal box of the present invention is as long as there are three kinds just can satisfy the requirement of various (PCC) powers.
