The CYBWG photovoltaic grid-connected cabinet is a key interface device used to connect centralized inverters to step-up transformers, or AC combiner boxes to step-up transformers, in photovoltaic power generation systems. It serves as an important node for power collection, protection, and grid connection.
The cabinet supports circuit-breaker input or direct input on the incoming side, while the outgoing side can be configured with a circuit breaker or load isolation switch, providing flexibility for different PV system architectures. With a robust electrical design and reliable protection configuration, the CYBWG cabinet ensures stable and safe long-term operation.
The CYBWG photovoltaic grid connected cabinet is an important component that connects centralized inverters with step-up transformers or AC combiner boxes with step-up transformers. The incoming line of this photovoltaic grid connected cabinet adopts circuit breaker input or direct input, and the output adopts circuit breaker or load isolation switch.
The busbar is connected by electroplated or purified busbar and provides secondary lightning protection. The maximum rated voltage of the system is AC690V, and the protection level is IP40 indoors and IP65 outdoors; The cables for secondary measurement and control include cables with a current greater than 2.5mm2, cables with a voltage greater than 1.5mm2, and cables with a control greater than 1.0mm2.
The measuring current transformer is a 0.5 level current transformer, andthe measuring transformer is a 0.2S level current transformer. Relevant functions can also be added according to customer requirements.
This product adopts professional electrical design and component selection, making the internal structure of the cabinet safe, simple, beautiful, convenient for on-site wiring and maintenance, and ensuring long-term stable operation of the equipment.
