Technical field
The present invention relates to solar-photovoltaic technology field, particularly a kind of fast and easy test photovoltaic is coated with the device of tin copper strips resistance.
(1) background technology
Be coated with the electrode extraction that tin copper strips is used for solar battery sheet when solar photovoltaic assembly is produced, connection in series-parallel photovoltaic cell; The resistance being coated with tin copper strips causes resistance in solar photovoltaic assembly larger compared with conference, the interior resistance of solar photovoltaic assembly when comparatively conference causes solar photovoltaic assembly to generate electricity internal consumption power larger, have influence on the output power of solar photovoltaic assembly, the sale of solar photovoltaic assembly is sold according to output power, so in order to improve the output power ensureing solar photovoltaic assembly, the main raw material(s) that strictly must control solar photovoltaic assembly is coated with the resistance of tin copper strips unit length.
Because photovoltaic is coated with the photovoltaic cell of tin copper strips for connection in series-parallel DC generation, so the resistance that measuring unit length is coated with tin copper strips generally uses digital D. C. bridge; The digital D. C. bridge that test photovoltaic is coated with tin copper strips has 2 current terminals, electric current is provided for giving tested painting tin copper strips, direct current bridge also has 2 potential ends, for testing the voltage drop between tested painting tin copper strips, thus draw the resistance of the painting tin copper strips between two potential ends, the unit length that general test is coated with the painting tin copper strips of tin copper strips resistance be 0.5 meter, 1 meter, 1.5 meters not etc., concrete steps are as follows:
1, the painting tin copper strips slightly grown than unit length of cutting;
2, two laboratory technicians are stretching being coated with tin copper strips, and it is unit length that 2 of being coated with on tin copper strips are selected in the 3rd laboratory technician's ruler measurement, and marks;
3, two of direct current bridge current terminals are clipped in the two being coated with tin copper strips, potential end is clipped in unit length two mark;
Be coated with tin copper strips more soft, stretching ability Measurement accuracy is needed to be coated with the length of tin copper strips, selecting 2 of being coated with on tin copper strips is unit length, unit length slightly length must be undertaken stretching by two laboratory technicians, it is unit length that 3rd laboratory technician selects 2 of being coated with on tin copper strips, employment is more, and experimental period is longer.
(2) summary of the invention
The present invention, in order to make up the deficiencies in the prior art, provides a kind of device just testing photovoltaic painting tin copper strips resistance fast, has the advantage that structure is simple, easy to operate, test employment is few, the test duration is short.
The present invention is achieved through the following technical solutions:
A kind of device just testing photovoltaic painting tin copper strips resistance fast, comprise the fixed head be made up of insulating material, it is characterized in that: described fixed head is rectangle, a long limit of fixed head indicates scale, and fixed head two ends are provided with the link post being wound around and being coated with tin copper strips.
More excellent scheme of the present invention is:
It is " ⊥ " font groove that the centre of described fixed head is provided with an xsect, groove is parallel with the scale face of fixed head, the link post being wound around and being coated with tin copper strips is installed in groove, described link post is cylindrical, link post is provided with the fixture block cooperatively interacted with groove, the outside surface of link post is provided with external thread and is provided with holding screw.
Being wound around by the painting tin copper strips cut during use is fastened on the link post at fixed head two ends, according to the calibration points be coated with on the unit length of tin copper strips and fixed head, the potential end of direct current bridge is connected and is coated with tin copper strips, current terminal is connected to the outside of potential end, tests.
The invention has the beneficial effects as follows: structure of the present invention is simple, easy to operate, a people can complete the test that unit length is coated with the resistance of tin copper strips, and the test used time is short, is suitable for wide popularization and application.
