On-Load Tap-Changing Dry-Type Transformer
The on-load tap-changing dry-type transformer integrates a vacuum on-load tap-changer, enabling stepless voltage regulation under load based on epoxy resin cast insulation. Rated voltage ranges from 10kV to 35kV, with capacity from 800kVA to 25MVA. It offers a wide voltage regulation range and short response time. It is suitable for applications requiring high voltage stability, such as power grid reactive power compensation hubs, photovoltaic/wind power grid connection points, and precision manufacturing industries.
The on-load tap-changing dry-type transformer is a transformer capable of adjusting voltage under load conditions, suitable for applications requiring frequent voltage adjustment to maintain power supply stability. This type of transformer is highly useful in various power systems and industrial applications. It is primarily used in urban power grids, factories, offshore platforms, substations, and other scenarios.
