Dry type transformer is a power equipment that achieves electrical isolation between windings through air or solid insulation materials. The main difference between its core structure and oil immersed transformer is that it does not require the use of insulation oil, thus having higher safety and environmental protection. Its winding is usually cast with epoxy resin or wrapped with Nomex paper to ensure insulation strength and mechanical stability, suitable for scenarios with high requirements for fire and explosion prevention.
Core strengths
Safe and reliable: No flammable liquid medium, can effectively reduce the risk of fire, suitable for densely populated areas or indoor installation.
Convenient maintenance: No need for regular replacement or monitoring of insulation oil, low operation and maintenance costs, and good anti pollution ability.
Strong environmental adaptability: It can operate stably within a wide temperature range of -25 ℃ to 40 ℃, and has good resistance to moisture and corrosion.
Energy saving and environmental protection: Low no-load loss, operating efficiency of over 98%, and no oil pollution in the production process and after disposal.
Application field
Dry type transformers are widely used in high demand industries such as commercial complexes, rail transit, data centers, new energy power stations, and chemical metallurgy. For example, in photovoltaic power generation systems, their high temperature resistance characteristics can be adapted to the high load requirements of the inverter output end; In high-rise buildings, compact design can save space in the distribution room.
development trend
Currently, the industry is further improving product performance by optimizing materials such as amorphous alloy iron cores and integrating intelligent monitoring modules such as temperature control and partial discharge sensors. In the future, with the increasing demand for low-carbon and digitalization, dry-type transformers will play a more critical role in the fields of smart grids and green energy.
