ZGS Type Photovoltaic Substation

The overall layout of the box transformer is compact, reasonable, and small in size; the main components are conveniently connected, and the amount of copper bars is greatly reduced; the incoming and outgoing cable wiring space and inspection space are large, making assembly and inspection easy. Box structure: All metal structural parts are sandblasted, hot-dip galvanized, and spray-painted to ensure that the equipment has strong corrosion resistance when used in humid and heavy salt spray environments. All door panels and wall panels have no interlayers and are filled in the middle. There are polyurethane and silicate composite insulation materials, which have excellent thermal insulation properties and ensure that the equipment can be put into operation safely and quickly in severe cold environments.

The transformer mainly adopts three-phase dual-winding oil-immersed no-load voltage-regulating low-loss power transformer. Other types of power transformers can also be configured according to requirements. The power transformer has adopted a series of reforms in materials, processes, and structure, making the electrical performance of the product reach the advanced level of similar international products. Its no-load loss and load loss are both lower than the national standard requirements, and it has the characteristics of high efficiency and low loss. It can save a lot of power consumption and operating costs, and has significant social benefits. The iron core is made of high-quality cold-rolled grain-oriented silicon steel sheets with full oblique joint stacking, and is filled with vacuum oil.

The low-voltage side can use intelligent circuit breakers or other series of low-voltage circuit breakers to distribute electric energy and protect lines and equipment from overload, undervoltage, short circuit, single-phase grounding and other faults. At the same time, a small maintenance transformer is installed on the low-voltage side to provide power at the user's maintenance site. The electrical beams of the low-voltage cabinet frame are all treated with hot-dip galvanizing for anti-corrosion.
