Small transformers have enough tank surface to radiate all the heat caused by their losses without exceeding the permissible temperature rise.
小型变压器具有足够的油箱表面积来散发所有由损耗引起的热而使之不超过允许的温升。
Thed ry-type transformers have been widely used in high buildings and power stations in cities due to its superiorities of flame retardancy, safety, easy maintenance, small volume, etc.
干式变压器由于具有难燃、安全、维护方便、体积小等特点,已在城市的高层建筑和电站等场所得到广泛的应用。
And unlike voltage regulators that employ ferro-resonant transformers, the AR-PRO is not sensitive to small errors in line frequency, making it ideal for use with generators.
而且不像雇用铁谐振变压器稳压器的AR - PRO是不敏感的线频率误差小,非常适合搭配发电机使用。
