Jan 20, 2024 · Transformer整体结构（输入两个单词的例子）. 为了能够对Transformer的流程有个大致的了解，我们举一个简单的例子，还是以之前的为例，将法语"Je suis etudiant"翻译成英文。. 第一步：获取输入句子的每一个单词的表示向量 ， 由单词的Embedding和单词位置的Embedding ...
Standard sizes for single-phase transformers include 15 kVA, 25 kVA, 50 kVA, and 100 kVA. They are designed to handle the power needs of homes and small businesses. Three-Phase Transformers: Used in industrial and large commercial applications, three-phase transformers come in sizes such as 150 kVA, 300 kVA, 500 kVA, 750 kVA, and up to 5000 kVA ...
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 ...
Transformer overcurrent protection is required to protect the primary windings from short circuits and overloads and the .secondary windings from overloads. Section 450.3 of the National Electrical Code (NEC) contains the requirements for overload protection of transformers. Overcurrent protection requirements depend on the following factors:
Control Transformer Explained. A control transformer is designed to provide stable voltage for control circuits in various applications. This transformer steps down the supply voltage to a lower, more manageable level suitable for controlling machinery and other electrical devices. Typically, the primary voltage is high, while the secondary ...
A high voltage transformer is an electrical device that transfers electrical energy between two or more circuits through electromagnetic induction. It operates by stepping up (increasing) or stepping down (decreasing) the voltage levels in power systems. High voltage transformers are typically used in transmission and distribution networks to ...
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 ...
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 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 ...
