Technical field
The utility model relates to a kind of proving installation of photovoltaic component terminal box thermal behavior, for assessment of the mechanical property of photovoltaic module terminal box adstante febre shell at work.
Background technology
Terminal box plays very important effect in photovoltaic module.It utilizes the performance of himself at photovoltaic module in shading, when electric current adaptation waits other unfavorable factor to occur, can also ensure its work, suitably reduce loss.Its principle of work is in photovoltaic module shading, and when electric current adaptation, internal by-pass diode operation, makes the power stage that photovoltaic module acquires a certain degree, and can not cause local overheating.But when its bypass diode work, the heating of terminal box also can be caused.If due to junction box unreasonable structure, or when bypass diode temperature is too high, when junction box is closed, heating causes material expansion, then terminal box casing deformation or shell is caused to throw off terminal box, the situation that this type of situation can cause terminal box to be leaked electricity.
Summary of the invention
The purpose of this utility model overcomes above-mentioned situation, provides a kind of proving installation of photovoltaic component terminal box thermal behavior, for assessing photovoltaic component terminal box thermal behavior.
According to the technical scheme that the utility model provides, the proving installation of described photovoltaic component terminal box thermal behavior comprises: pressure ball, load beam, ballast support bar, weight and sample holder, horizontal positioned test sample terminal box on described sample holder, pressure ball is pressed in test sample terminal box upper surface, pressure ball is arranged on load beam bottom, ballast support bar is installed in load beam side, and weight is arranged on ballast support bar.
Concrete, described ballast support bar and weight symmetry be distributed in load beam both sides.Described pressure ball, load beam, ballast support bar and sample holder all adopt stainless steel to make.
Described pressure ball diameter is 2.1mm ~ 2.5mm.
The utility model has the advantages that: the proving installation devising a kind of special photovoltaic component terminal box thermal behavior, is configured with a pressure ball at pressure point locations, apply fixing pressure on terminal box body surface; Binding experiment condition carries out analog operation, can test the compression resistance performance of box body insulating material.
