1.Pneumatic transmit system

2.Machine shift device

3.Sample holder:

4.Optical fiber Superhigh speed measure system

purpose 

To verify that the module is capable of withstanding the impact of hailstones 

Parameter

1 Pneumatic transmit system :  adjust the transmit speed of ice ball which in thetransmit tube

2.Machine shift device: manual move the place of barrel ,Microcomputer change the place of the barrel through control Gearing. tracing point with   infrared ray
3.Sample holder: Design the machine shift device and sample holder conform to sample size,standard size :2000*1350(L*H)

4.Speed test system: include detection sensor ,High-speed response module,Software modules,

 Principle

Make a ball mould which inner diameter in 25mm,put the ice ball in the in the barrel,then open the solenoid valve,pushing the ice ball impact the PV module with speed in 23m/s.detection the impact range,Determine  whether the PV mould qualified or not ,after appearance inspection,measurement to insulation resistance and maximum power

Effective impact area: >2.0m×1.35m
Send speed setting: 23.0m/s
Speed measure accurately: ±2%
Speed windage range: ±5%

 basic structure:
Gun automatic positioning
Pneumatic send system
Module bracket (removable)
Optical fiber Superhigh speed measure system

Hail mold (inside diameter:25mm+5%)
Hail diameter: 25mm±2%
Hail mass: 7.53g±2%
