要是没有变压器来调节电压，远距离输送电力是不可能的。
Were there no transformers to adjust the voltage, long-distance transmission of electricity would be impossible?
该电路是指由一个电源，这就是为什么没有变压器，整流器，或者过滤器供电电容的示意图。
The circuit was meant to be powered by a power supply, which is why there is no transformer, rectifier, or filter capacitors on the schematic.
我并没有说明，其工作原理的细节，但这些方程，是电容器和变压器运作的基本原理。
I don't really claim that I have given you enough details to understand how they work, but basically these equations are the heart of understanding how things like capacitors and transformers work.
这是最有趣的，因为它没有差别的位置，间接电话线或变压器的杆位。
This is most interesting because it makes no difference concerning the location of the overhead phone wires or the pole transformer.
我没有遇到任何配件或者变压器的问题，同时，可以带着它去任何地方。
I have not had an issue with any of the parts or AC adaptor and it has travelled everywhere with me.
国外公司还没有遇见到他们崭新的牵引变压器最终会在中国工厂被重建并被应用到其他地方甚至被出口。如果有一天他们开始喊冤会怎样呢？
What if the foreign firm, who did not foresee that their shiny new traction transformers would end up being rebuilt in Chinese factories and redeployed elsewhere, or even exported, cries foul?
特种变压器的电抗计算非常复杂，又没有现成公式可用。
It's very complex to calculate the reactance of special transformer, and no formula can be made use of.
公司以前设计开发时，设计文档不是强制的，所以我没有太多制作新变压器的基础。
The company developed the previous design when design documentation was not mandatory, so I did not have a set of requirements on which to base the new transformer.
本文描述了一种非接触式电力传输系统，使用可拆卸的变压器，这是火花自由和没有揭露的行为暴露于环境。
This paper describes a contact-less power transmission system using detachable transformer, which is spark free and no uncovered conduct is exposed to the environments.
鉴于目前国内对于变压器中性点直流电流还没有一个统一的标准，有必要尽快加以制订和实施。
Since there is no unified standard for DC current through the neutral point of transformer in China, it is necessary to define and enforce a unified one as soon as possible.
我想问一下你们的使用环境(场合)，周围有没有大型变压器？
I want to know the circumstances while you use it. Is there any large-scale transformer around you?
由于变压器和滤波电容(假定)足够大，因此当负载阻抗改变时供电电压几乎没有变化。
Depending upon the transformer and storage capacitor sizes in the power supply the output voltage will not vary significantly when the load impedance is changed.
但我们将变压器产品移到海外工厂生产，工厂正确地使用没有空气缺口的变压器。
Once we moved production of the transformers to the overseas factory, that facility correctly built the transformers without an air gap.
这种方法有很多优点，可以多选择性，长时间跟踪，并且对油箱内气体的没有影响，对变压器本身也没有电磁影响等。
This method offers high selectivity, long life, no influence of surroundings gases, no electromagnetic induction and so on.
