Overview

CYBWG photovoltaic grid-connected cabinet is an important part of undertaking centralized inverter and step-up transformer or AC combiner box and step-up transformer, the inlet line of this photovoltaic grid-connected cabinet adopts circuit breaker input or direct input, output adopts circuit breaker or load isolation switch, bus is connected by electroplating or purified busbar, and provides secondary lightning protection, the system rated voltage is AC690V, and the protection level indoor is IP40, IP65 outdoors; Cables for secondary measurement and control, cables with currents greater than 2.5mm^2, cables with voltages greater than 1.5mm^2, cables with control greater than 1.0mm2, current transformers with 0.5 current transformers for measuring current, and 0.2S current transformers for metering transformers. It is also possible to add related functions according to customer requirements. This product adopts professional electrical design and component selection, so that the internal structure of the cabinet is safe, concise, beautiful, convenient for on-site wiring and maintenance, and ensures the stable operation of the equipment for a long time.

Functions and Features

▪ It can be either fixed installation design or plug-in design;

▪ The use of Feng company or domestic and foreign brand circuit breakers and components combined into a functional unit, with excellent technical performance, safe and reliable;

▪ It can be composed of various standard unit modules for customers to choose and assemble at will;

▪ The isolation between areas and the mutual isolation between the incoming and outgoing lines of the functional unit is adopted to effectively strengthen the safety protection performance;

▪ Combined prefabricated structure, all structural parts of the frame are firmly connected with screws, the frame, doors and panels are electrostatically sprayed after phosphating treatment, and all non-sprayed parts are galvanized and passivated. It can meet the requirements of various components and meet different working environments to achieve the corresponding protection level;

▪ The skeleton is made of steel plate, and the skeleton can be equipped with a hole with a module of 25mm, which can be expanded for various purposes.

▪ High breaking capacity, good dynamic and thermal stability, flexible and convenient combination of electrical schemes, strong practicability, and the main parameters reach the level;

▪ The reset is light, the mechanical strength and assembly accuracy are high, and the appearance is beautiful.
