The BWG-R mainly consists of isolation switch, circuit breaker and relevant control components, and is called “grid-connected cabinet” because it connects the power generation system and the power grid system and is installed with complete grid-connecting protection devices to play the role of power generation and grid connection. Existing in the photovoltaic system as the main outlet of the photovoltaic power station, the photovoltaic grid-connected cabinet is the distribution device connecting the photovoltaic power station and the power grid, and can protect and measure the total photovoltaic power generation, facilitate troubleshooting and management, and improve the safety and economic efficiency of the power generation system. It has such all-round protection functions as voltage loss opening, voltage presence closing, over-current protection, over-voltage protection, islanding protection, anti-reverse-current protection, harmonic control and reactive power compensation, and it can display the operating parameters and status of the photovoltaic power generation system, so it is widely applied to the photovoltaic power generation systems; it can be used in combination with the grid-connected inverter to form a complete photovoltaic power generation system solution.
◆Either draw-out air circuit breaker or isolation switch + fixed air circuit breaker can be used;
◆Circuit breakers and components from the Company or of well-known brands at home and abroad are combined into functional units to achieve excellent technical performance;
◆The isolation between zones and the mutual isolation between incoming and outgoing lines of functional units are used to effectively enhance the safety protection performance;
◆With combined assembly structure, all structural parts of the frame are connected and fastened by screws, the frame and door panel undergo phosphating and electrostatic spraying, and all parts not sprayed are galvanized and passivated. The requirements for various components and different working environments can be met, and the corresponding ingress protection rating is reached;
◆The skeleton is made of high-quality steel plate;
◆High breaking capacity, good dynamic and thermal stability, flexible and easy combination of electrical schemes, strong practicality, and main parameters reaching international advanced level;
◆Light weight, high mechanical strength and assembly precision, and aesthetic appearance.
