BWG Photovoltaic Grid-Connection Cabinet

Overview

The BWG photovoltaic grid-connection cabinet is an important component connecting centralized inverters to step-up transformers or AC combiner boxes to step-up transformers. The input of this photovoltaic grid-connection cabinet uses circuit breaker input or direct input, and the output uses circuit breakers or load disconnectors. The busbar is connected using electroplated or passivated busbars, and provides secondary lightning protection. The maximum system rated voltage is AC690V. The protection level is IP40 for indoor use and IP65 for outdoor use. Cables for secondary measurement and control: current cables > 2.5mm2, voltage cables > 1.5mm2, control cables > 1.0mm2. Measurement current transformers are class 0.5, and metering current transformers are class 0.2S. Additional functions can also be added according to customer requirements. This product uses professional electrical design and component selection, ensuring a safe, simple, and aesthetically pleasing internal structure, convenient on-site wiring and maintenance, and long-term stable operation of the equipment.

Functions and Features

? Can be designed with either fixed installation or plug-in design;

? Uses our company's or well-known domestic and international brands of circuit breakers and component functional units, with excellent technical performance, safety, and reliability;

? Can form various standard unit modules for customers to choose and assemble freely;

? Uses isolation between areas and mutual isolation between functional unit incoming and outgoing lines, effectively enhancing safety protection performance;

? Combined assembly structure; all structural parts of the frame are securely connected with screws. The frame, doors, and panels are all phosphated and then electrostatically sprayed with plastic. Non-sprayed parts are all galvanized and passivated. It can meet the requirements of various components and adapt to different working environments, achieving corresponding protection levels;

? The skeleton is made of steel plate, with holes on the skeleton at a module pitch of 25mm for various extensions. There are two incoming methods: top and bottom incoming;

? High breaking capacity, good thermal stability, flexible and convenient electrical scheme combination, strong practicality, with main parameters reaching advanced international levels;

? Light weight, high mechanical strength and assembly accuracy, beautiful appearance.
