Product Brief

YBW‑G series European‑style box‑type substation dedicated for photovoltaic application is a complete‑set power distribution equipment composed of high‑voltage switchgear, power transformer, low‑voltage switchgear, intelligent control equipment, connecting parts and auxiliary devices. It is specially applied in photovoltaic power generation systems to step‑up the low‑voltage output from inverters (0.69 kV, 0.27 kV or 0.315 kV) to grid voltage (10 kV or 35 kV) for grid‑connection. Its transformer is generally oil‑immersed or dry‑type with double‑split or double‑winding configuration.

Product Features

1. The design complies with the requirements of GB/T 17467‑2010 and GB/T 8754‑2007.
2. The high‑voltage power supply system supports ring‑network power supply, terminal power supply, dual‑source power supply and other modes, and can be customized for users. High‑voltage metering components can be equipped to meet high‑voltage metering requirements. The high‑voltage cabinet provides multiple protection functions against transformer short‑circuit, overload and other faults.
3. Either oil‑immersed transformer or dry‑type transformer is optional for the transformer compartment. Room‑temperature monitoring device and self‑starting ventilation and cooling device can be installed as required.
4. According to user requirements, the low‑voltage compartment adopts panel‑mounted cabinet structure to form customized power‑supply schemes. Inverter outgoing circuits can also be tailor‑made. Moulded‑case circuit breakers are equipped in the low‑voltage compartment, and air‑circuit breakers are optional upon request, providing full‑range protection against overload and short‑circuit of transformers and inverters.
5. Fixed‑type installation is adopted for high‑voltage and low‑voltage complete‑set assemblies as well as transformers. Man‑holes and operation space are reserved inside the substation for convenient installation and maintenance.
6. A control (auxiliary) transformer compartment is arranged inside the substation. It converts the output voltage from inverters to utility power (single‑phase 220 V, three‑phase 380 V) for powering auxiliary equipment and lighting devices, ensuring reliable operation of the box‑type substation.
7. The high‑voltage and low‑voltage compartments adopt reasonable layout with comprehensive anti‑mis‑operation interlock functions for flexible performance. All components installed in high‑voltage and low‑voltage compartments feature reliable performance and easy operation. Operating status can be directly observed and operated through meters and indicators on cabinet panels for clear status indication.
8. With attractive appearance, the European‑style box‑type substation can be customized into landscape‑style appearance according to user preferences. The enclosure color can be well harmonized with surrounding environment for environmental embellishment and beautification.
9. Photovoltaic‑specific surge protective devices are adopted on the low‑voltage side to provide professional protection against inverter‑generated harmonics, overvoltage and electromagnetic interference.

Intelligent integrated measurement and control devices (comprehensive protection or relay protection) can be configured for remote monitoring and operation upon user requirements.
