Renewable Energy Dual-Split Transformer
The SF series split-type Scott transformer for new energy photovoltaic and energy storage applications features a relatively large rated capacity. The low voltage side is split into two windings, allowing it to serve two unit substations simultaneously. The two unit substations can be used together or independently, providing users with flexible switching options. The main body adopts an oil-immersed self-cooling off-circuit tap-changing fully sealed structure. It is mainly composed of the transformer core and windings assembly, tank, radiators, high and low voltage insulating bushings, oil level gauge, pressure release valve, temperature controller, Buchholz relay, breather, etc. It is a key core component of the Scott-type unit substation. This product series offers a wide capacity range and is available for voltage levels up to and including 40.5kV.
