Abstract

The invention discloses a load pressure simulation device for a photovoltaic component. The load pressure simulation device comprises a static mechanical load device and a dynamic mechanical load device, wherein the static mechanical load device and the dynamic mechanical load device are arranged in a case (1); during the static load test, an intelligent digital instrument (3) is used for automatically inflating and deflating an air bag (4) to simulate static load pressure; during the dynamic load test, the dynamic load device is transferred onto the static load device, and the photovoltaic component to be tested is fixed on a lifting table (5) and is electrified; when the air bag (4) is inflated to corresponding pressure, the weight of a sand bag arranged on a back plate of the photovoltaic component can be calculated according to the area of the photovoltaic component, so that a motor rotates to drive the lifting table (5) to move up and down to be in full contact with the surface of the air bag (4), and thus a requirement on the test of simulating the dynamic load is met.

Description

technical field [0001] The invention relates to a test device, in particular to a device for static and dynamic load tests of photovoltaic components. Background technique [0002] Photovoltaic solar power generation is a new type of energy, clean energy. Under the condition of energy shortage in today's society, photovoltaic solar power generation has attracted more and more attention from the society, and more funds have been invested in the construction of photovoltaic power stations. Photovoltaic solar modules are made of individual cells connected in series / parallel and packaged. Due to the impact of static and dynamic loads such as long-distance transportation, unreasonable handling of personnel, wind pressure, and snow pressure, internal cells of photovoltaic solar modules will be cracked and deformed and damaged. [0003] In the prior art, the static load and dynamic load test devices of photovoltaic solar modules are independent of each other, and a set of static l...
