二、何为 Transformer？. Transformer 架构擅长处理文本数据，这些数据本身是有顺序的。. 它们将一个文本序列作为输入，并产生另一个文本序列作为输出。. 例如，将一个输入的英语句子翻译成西班牙语。. Transformer 的核心部分，包含一个编码器层和解码器层的堆栈 ...
Power Transformers. Incorporating state-of-the-art technology and innovative design, modern power transformers play a crucial role in transforming electrical voltage from one level or phase to another. With high efficiency and the ability to adapt to various voltage levels, power transformers serve as essential components in power distribution ...
Transformer Ratings. Engineers rate power transformers according to the maximum output voltage and current they deliver. For a given unit, we'll often read or hear about the volt-ampere (VA) capacity, which equals product of the nominal output voltage and maximum deliverable current. A transformer with 12 V output, capable of providing up to 10 ...
Transformer 和 MLP 之间的主要差异在于它们是如何处理输入的。. Transformer 通过使用 self-attention 来捕获输入之间的全局依赖关系，而 MLP 则使用多层神经网络和全连接层来捕获输入之间的局部依赖关系。. 引用：Vaswani, Ashish, et al. "Attention is all you need." Advances in neural ...
Pole mounted transformers play a crucial role in the distribution of electrical power in residential and rural areas. By stepping down high voltage electricity to a lower voltage suitable for consumer use, these devices ensure a reliable and efficient power supply. This article delves into the purpose, capacity, installation requirements, and ...
Single-Phase Transformer Connections. Single phase transformers, like other electrical devices, may be connected into series or parallel arrangements. For example, distribution transformers are normally wound with the secondary or low-voltage windings that can be connected in series or parallel. The availability of primary voltages and the ...
Electrical power transformers are electrical devices commonly used in engineering that transforms both the voltage and the current of the electricity flowing through it. It is made up of a coil wrapped around an electromagnet that transfers the electricity. Unlike distribution transformers, power transformers are designed to operate at 100% ...
The underground transformer is essential in a modern electrical distribution system, providing a reliable and aesthetically pleasing solution for urban and suburban power distribution. It is an electrical device designed to convert high-voltage electricity to lower voltages suitable for residential and commercial use, installed below ground ...
Understanding transformer sizing is critical for optimal electrical system performance, safety, and efficiency. By considering the capacity, kVA rating, load calculation, voltage ratio, primary and secondary windings, impedance matching, efficiency, temperature rise, and short-circuit current, it is possible to select the ideal transformer size ...
Transformer Insulation. Insulation systems in power transformers consist of a fluid—either liquid or gas—together with solid materials. Petroleum-based oils have been used to insulate power transformers since 1886 and the mid-1970s when the flammability of mineral oil was a concern, but it has since been completely phased out of transformer ...
