Safe and reliable high-voltage-resistant testing equipment for flexible CIGS solar module
Technical Field
The invention belongs to the field of new energy, relates to solar module production test equipment, and particularly relates to safe and reliable flexible CIGS solar module high-voltage resistance test equipment.
Background
The high-efficiency thin-film solar cell taking copper indium gallium selenide as an absorption layer is generally called a copper indium gallium selenide cell (CIGS cell), and the CIGS thin-film solar cell is taken as a flexible solar cell and is characterized by high technical requirement, portability, no phenomenon of light-induced decay, high conversion efficiency and stable performance. According to the traditional high-voltage-resistant test of the flexible CIGS solar module, the module is placed on a test platform, an operator connects a cable to a power supply of a tester for power-on test, no related protection measures are provided, the CIGS module is also exposed in the environment, and if the operator accidentally touches the module, an accident situation can occur. In the newly developed flexible CIGS solar module, because the CIGS solar module is flexible and deformable, when the flexible CIGS module is tested, a pressing plate is required to be matched with a test platform to press the module so as to ensure that the test is carried out smoothly. The traditional pressing plate action is manually completed, and the production efficiency is low. For the automatically lifting pressing plate, a tester is possibly clamped and injured by the automatically lifting pressing plate in the testing process, and the automatically lifting pressing plate improves the production efficiency but has potential safety hazards.
Disclosure of Invention

The clamp plate is pressed flexible solar energy component and is established and test on test platform, the clamp plate encircles and inlays that the clamp-proof insulated strip of establishing be elastic structure, when the people hand, foreign matters such as rod stretch into the clamp plate below from the outside, prevent pressing from both sides the insulated strip and contact with the foreign matter earlier than clamp plate, under the foreign matter extrusion effect, prevent pressing from both sides the insulated strip and warp, last electrically conductive sheetmetal and lower electrically conductive sheetmetal in the cavity contact each other and lean on, the scram switch-on triggers the scram action, realize emergency stop, reduce the clamp injury accident. Compare traditional anti-pinch system that detects scram behind certain pressure, this device trigger sensitivity is high, and the mistake rate of touching is low, because prevent that the clamp insulating strip contacts with the foreign matter earlier when warping, the clamp plate has not contacted the foreign matter yet, even there is certain delay in the scram trigger process, also can not produce very big clamping-force to the foreign matter.
Preferably, the test platform is circumferentially provided with a lower insulating strip, and the anti-pinch insulating strip and the lower insulating strip are arranged in a staggered mode inside and outside. Prevent that normal during operation from preventing pressing from both sides the insulator strip and support from top to bottom with lower insulator strip and lean on, influence clamp plate and test platform's clamp tightly. The anti-pinch insulating strip and the lower insulating strip can be rubber strips, silica gel strips, polyimide composite glass cloth, composite films, polyimide paint and the like.
Preferably, the clamp plate is circumferentially provided with clamp grooves, and the upper end of the anti-clamping insulating strip is provided with a clamp connector matched with the clamp grooves of the clamp plate.
Preferably, the height of the upper conductive metal sheet is not higher than the bottom surface of the pressing plate.
Preferably, the anti-pinch insulating strip is provided with a plurality of cavities in an up-and-down distribution mode, and the upper conductive metal sheet and the lower conductive metal sheet are arranged in the cavity at the lowest position. The height difference between the emergency stop trigger point and the bottom surface of the pressure plate is increased as much as possible, the fault tolerance rate is improved, the sensitivity of deformation contact of the cavity which is lower is higher, the emergency stop trigger reaction time is shortened, and the safety is improved.
Preferably, a group of linked switches which can control the pressing plate to press down only by pressing simultaneously are arranged on the rack, and the group of linked switches comprise a pair of switches operated by one person or two pairs of switches operated by two persons. During one-man operation, a pair of linked switches must be pressed simultaneously to both hands, and during two-man operation, two pairs of linked switches must be pressed simultaneously to four hands, just can start the clamp plate and push down, and the mistake is started when avoiding the cooperation error to lead to the flexible solar energy component of manual adjustment.
Preferably, the distance between a pair of switches operated by the same person is not less than 30cm and not more than 150 cm.
Preferably, the feeding side of the test platform is provided with a blowing dust removal device, and the blowing dust removal device is provided with a strip-shaped air outlet blowing air downwards and outwards in an inclined mode.
Preferably, the upper surface of the test platform and the lower surface of the pressing plate are flexible carbon fiber conducting layers. The measured CIGS component can be wrapped by the sponge body made of the carbon fiber conductive material well, and a test blind area is avoided.
Preferably, the flexible carbon fiber conductive layer uses graphite felt or conductive cotton.
According to the invention, the anti-pinch insulating strips triggered to stop suddenly by extrusion are arranged around the pressing plate, so that when a hand of a user stretches into the lower part of the pressing plate in a starting state of the pressing plate, the pressing plate can be stopped suddenly, and the operation safety is ensured; this device triggers sensitivity height, and the mistake rate of touching is low, because prevent pressing from both sides the insulated strip earlier with the foreign matter contact when warping, the clamp plate still does not contact the foreign matter, even there is certain delay in the scram triggering process, also can not produce very big clamping-force to the foreign matter.
