Chinese box change

Chinese-style prefabricated substations scientifically combine high-voltage and low-voltage distribution cabinets, transformers, and other components according to a specific wiring scheme, installing them in a fully enclosed, movable steel structure enclosure. Compared to European-style prefabricated substations, they are more compact in size; compared to American-style prefabricated substations, they are easier to inspect and maintain. They are widely used in photovoltaic and wind power applications.

1. Compact structure, small size, easy and flexible installation;

2. Fully insulated, fully sealed structure, safe, reliable, maintenance-free, and reliably protects personal safety;

3. High-voltage side uses double fuse protection, with the plug-in fuse having dual-sensitive fuse wires (temperature and current), and the backup fuse being a current-limiting fuse, reducing operating costs;

4. High-voltage incoming line adopts cable connector structure, fully insulated, safe, reliable, and easy to operate;

5. Can be used in both ring networks and terminal systems, with convenient switching and improved power supply reliability;

6. The transformer has a three-phase three-limb or three-phase five-limb structure, and the iron core adopts stepped joint technology or rolled iron core technology, resulting in low noise, low loss, and strong resistance to short circuits and overloads.

7. The enclosure can be designed with anti-corrosion and specially painted according to the requirements of the operating environment, with "three-proof" functions, namely anti-condensation, anti-salt spray, and anti-mildew functions, and can meet the anti-corrosion requirements of high temperature and high humidity environments.
