Title:
SHUTDOWN SYSTEM FOR PHOTOVOLTAIC ASSEMBLY ARRAY
Document Type and Number:
WIPO Patent Application WO/2019/148483
Kind Code:
A1
Abstract:
A shutdown system for a photovoltaic assembly array, for performing shutdown control on a photovoltaic assembly array. The system comprises a shutdown controller and a plurality of shutdown devices. The shutdown devices each have a first connection terminal and a second connection terminal. The shutdown devices and photovoltaic assemblies are connected in series by means of the first connection terminals between a direct current bus. Each of the shutdown devices is located between adjacent photovoltaic assemblies. The shutdown devices and the shutdown controller are connected in series by means of the second connection terminals. The shutdown controller controls all of the shutdown devices in a control circuit to simultaneously turn on or shut down the same under a pre-determined condition, such that a photovoltaic assembly circuit is connected or disconnected. The shutdown system achieves automatic, fast, and safe shutdown of each assembly in a system, thereby ensuring safety of maintenance personnel.
