Static pressure testing device of solar cell assembly

Abstract

The invention relates to a static pressure testing device of a solar cell assembly. The static pressure testing device comprises a stander, an assembly support frame, a water channel, a pressure sensor, a circulating cistern, a self-priming water pump and a lifting device. In the static pressure testing device, the theory of static pressure testing by adding water into the water channel is adopted, wherein the water channel is arranged on a load-bearing plate on the upper surface of the solar cell assembly through an electric block; pressure can be uniformly exerted on the surface of the solar cell assembly by water due to high flowability thereof; as the weights of the water channel and the load-bearing plate are known and not changed, the pressure exerted on the surface of the solar cell assembly can be regulated only by adding the water into the water channel; and the exerted pressure can be precisely controlled by arranging a pressure sensor at the bottom of the water channel. The static pressure testing device has the advantages of simple and precise pressure control, simple, convenient and quick operation, strong practicality, recyclable balance water, no water resource waste, no pollution to the environment, and no damage to the surface of the solar cell assembly during the whole testing process.

Description

Technical field: [0001] The invention relates to a testing device for a solar battery module, in particular to a pressure-resistant testing device for a solar battery module. Background technique: [0002] Solar cell modules must bear the pressure of strong winds and the gravity of ice and snow during long-term outdoor use. In order to simulate the real situation to test the pressure-bearing performance of solar cell modules, according to national standards, the surface bearing pressure of solar cell modules must be greater than 2400Pa or 5400Pa. For this reason, people must test the pressure bearing capacity of the surface of the solar cell module. People try to observe whether the glass of the solar cell module is crushed after uniformly increasing the pressure of 2400Pa or 5400Pa on the surface of the solar cell module. The existing testing device includes a manipulator testing device, which evenly distributes a number of manipulators on the surface of the solar cell modu...

Problems solved by technology

However, in the actual operation process, the process of applying the above-mentioned pressure with sand is complicated and lengthy. It not only takes a long time to remove the sand, but also scratches the glass if you are not careful. The operation is demanding and difficult, and the pressure control is also difficult to be accurate. master
