6~35kV Dry-type Three-phase Double-winding No-load Tap-changing New Energy Power Generation Side Transformer for Photovoltaic, Wind Power and Energy Storage
6~35kV Dry-type Three-phase Double-winding No-load Tap-changing New Energy Transformer; adopts scenario-specific design, targeting the characteristics of high harmonic content and large load fluctuation in photovoltaic inverter and wind turbine frequency conversion output, using high harmonic-resistant insulation system with partial discharge ≤5 pC. The low-voltage winding is wound with aluminum foil or copper foil, effectively suppressing harmonic eddy current losses, improving the transformer's short-circuit resistance and extending service life. High reliability and low loss; the core is made of high-quality cold-rolled oriented silicon steel sheets with 45° full miter joints, reducing no-load loss by an additional 3%-5% compared to the GB energy efficiency Level 1 limit value. The windings are vacuum pressure impregnated (VPI), moisture-proof, dust-proof and salt-spray-proof, meeting long-term operation requirements for offshore wind power and high-humidity areas. Intelligent monitoring; standard three-phase temperature patrol inspection and RS485/Modbus communication interface, which can be connected to SCADA system to realize remote fan control, over-temperature alarm and trip functions. Modular and compact; volume is 30% smaller than traditional oil-immersed type, can be directly installed at the bottom of wind turbine tower or inside photovoltaic box-type substation, saving civil construction investment. Oil-free design, maintenance-free, meeting high environmental protection and fire protection requirements.
