Description
Technical field
The present invention relates to the improvement of photovoltaic panel inter-module connecting device in a kind of solar energy photovoltaic system, be specifically related to a kind of photovoltaic MC4 joint mounting structure that can effectively prevent photovoltaic MC4 joint short-circuit fire, take this to improve the fire resistance of MC4 joint.
Background technology
The utilization of solar energy is more and more universal, and solar energy photovoltaic system to be a kind of exposure will produce galvanic TRT in the sun, photovoltaic panel assembly therein can make different shape, and photovoltaic panel can be interconnected to obtain more electric power.
Existing solar energy photovoltaic system is to be connected in series by the direct current cables of photovoltaic panel inter-module, form again through square formation in parallel forms a system, the MC4 joint being connected between plate with plate is an easy short circuit and the place easily ignored, outside it is chronically exposed to, owing to production technology is uneven, link position easily causes loose contact, and causes there is disaster hidden-trouble.
Summary of the invention
It is an object of the invention to overcome the deficiency of prior art, it is provided that a kind of mounting structure that can be effectively improved photovoltaic MC4 joint fire resistance.
The technical scheme realizing the object of the invention is as described below:
A kind of photovoltaic MC4 joint fire-retarding device, it is characterized in that: described mounting structure includes an accommodating cavity, these accommodating cavity two ends respectively arrange a draw-in groove, MC4 joint is arranged in this containing cavity body, MC4 joint two ends are connected with direct current cables respectively, the direct current cables at these MC4 joint two ends each from top to bottom sticks into and in the draw-in groove of the accommodating cavity of its homonymy, arranges fire-proof packing in this containing cavity body.
It is provided with reinforcement bottom described accommodating cavity inner wall.
Four reinforcements it are provided with bottom described accommodating cavity inner wall.
Described reinforcement is low wide and up narrow taper.
Described draw-in groove is V-shaped, and this V-Bottom portion has a circular notch.
