Pneumatically controlled device for manual and automatic shutdown of photovoltaic modules, has pneumatic switches attached parallel to generator outputs by using photovoltaic modules, which electrically short circuit generator outputs

摘要

The device has pneumatic switches (2, 4) attached parallel to generator outputs by using photovoltaic modules (1), which electrically short circuit the generator outputs. The switches are electrically closed in pressure less state. The pneumatic switches are connected with a pneumatic control line (3), so that pressure in the control line prevails as the control inputs of the switches. The pneumatic control line does not withstand to operating pressure at super elevated temperatures by suitable material along with bending points of a girder construction.
