ZBHBWG photovoltaic grid connected cabinet is an important component that undertakes centralized inverters and step-up transformers, or AC combiner boxes and 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 with electroplated or purified busbar, and can provide primary 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 voltage greater than 1.0mm2. The measuring current transformer is a 0.5 level current transformer, and the measuring current transformer is a 0.2S level current transformer. Related 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.
? Both fixed installation and plug-in designs can be used;
? We use our company or well-known domestic and foreign brand circuit breakers and component combinations to successfully assemble functional units, which have excellent technical performance and are safe and reliable;
? Various standard unit modules can be formed separately for customers to choose and assemble at will;
? Adopting isolation between regions and mutual isolation between incoming and outgoing lines of functional units, effectively enhancing safety protection performance;
? Combined assembly structure, all structural components of the frame are firmly connected with screws, and the frame, doors, and panels are treated with phosphating and electrostatic spraying. Non spraying components are all galvanized and passivated. Capable of meeting the requirements of various components and meeting different working environments, achieving corresponding protection levels;
? The skeleton is made of high-quality steel plate, which can have holes with a modulus of 25mm on the skeleton, which can be expanded for various purposes. There are two ways to enter the wire: upper and lower;
? High breaking capacity, good dynamic and thermal stability, flexible and convenient electrical scheme combination, strong practicality, and main parameters reaching international advanced level;
? Light reset, high mechanical strength and assembly accuracy, and beautiful appearance.
