1. Selection Notes
In evaluating transformers, attention is directed towards their efficiency, temperature rise, insulation levels, and other pivotal performance indicators, which are crucial in determining their operational proficiency and dependability. To ensure cost-effectiveness, the decision-making process must consider the totality of costs, including those for equipment, transportation, installation, and related factors, ultimately selecting the transformer model that offers the best value for money.
2. Application Scenarios
Electric Energy Transformation & Dispatch: Three-phase, three-winding transformers serve as pivotal components in power systems, facilitating power conversion, transmission, and subsequent distribution. They seamlessly interconnect various voltage-level transmission systems, bolstering transmission efficiency, and guaranteeing the steadfast operation of the power grid.
Transformers in Substation Infrastructure: Within substations and distribution hubs, these transformers are instrumental in regulating power supply levels, either stepping it up or down, to preserve the consistency of power transmission. They underpin the reliability and stability of the grid, ensuring a reliable power flow to end-users.
