YBW‑series box‑type substation is a complete‑set power distribution equipment consisting of high‑voltage switchgear, power transformer, low‑voltage switchgear, intelligent control equipment, connecting components and auxiliary devices. It is specially used for various urban buildings, roads and building power‑consuming facilities. It can be configured for ring‑network power supply system or serve as terminal power‑supply equipment for radial power grids. Intelligent measurement and control devices can also be equipped to realize remote telemetry.
ZGS‑G series American‑style box‑type substation dedicated for photovoltaic application is a combined‑type transformer. Its high‑voltage fuse, multi‑position load switch and off‑circuit tap‑changer are integrated as internal components and installed inside the transformer oil tank, with low‑voltage complete‑set equipment mounted on the outside of the transformer. Applied in photovoltaic power generation systems, it steps 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. It generally adopts double‑split or double‑winding oil‑immersed transformer, and the high‑voltage switch is oil‑immersed type.
YBW‑G series European‑style box‑type substation dedicated for photovoltaic application is a complete‑set power distribution equipment consisting of high‑voltage switchgear, power transformer, low‑voltage switchgear, intelligent control equipment, connecting components and auxiliary devices. It is specially used 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.
YB□‑12 type prefabricated substation is a complete‑set product integrating switchgear, transformer and low‑voltage electrical equipment. It acts as power transformation and distribution equipment for urban buildings, residential communities, small‑ and medium‑sized factories, mines, oil fields and other power‑consuming users. It features high integration, small size, compact structure, high reliability, less on‑site installation work, short installation cycle and good movability. It can also serve as terminal power‑supply equipment for radial power grids and be equipped with intelligent measurement and control devices to realize remote telemetry. As a new‑type complete‑set equipment, its appearance and color can be adjusted to adapt to surrounding environments for landscape beautification.
The box‑type inverter all‑in‑one unit integrates DC cabinet, inverter, medium‑voltage transformer, ring main unit and system monitoring functions. Equipped with standard power dispatching interfaces, it provides a one‑stop inverter‑unit solution covering the whole process from DC output of photovoltaic modules to grid‑connection.
