摘要
电网损耗占供电容量7.7%,而变压器损耗占其中大部分,因此采用节能变压器是节能工作的重大措施。降低变压器损耗可从降低铜损、铁损、杂损,消除"大马拉小车",提高运行性能着手,采取改进材质、改造部件结构、使工作原理与工作特性相适应等措施。介绍了超导、非晶、卷铁心、R型卷铁心、立体铁心、单相柱上、调容量、有载调压、中阻抗除尘、低压节电器、铜铁损耗比适配、采用细磁畴高导磁硅钢片、低阻低损导线等13种节能变压器的原理、结构、特点并加以对比。如措施组合,节能会更多。指出S7、S9、S11系列变压器的损耗比较适宜单班制生产,对连续负载和农村负载并不节能。
It is the significant measure to use the energy saving transformer for the work of energy saving, because the power grid losses take 7.7% of power supply capacity, in which transformer loss takes the most. It can be reached to reduce transformer loss from the idea of reducing the losses in copper, iron and stray loss, and having operation performances with high efficiency and eliminating the phenomenon of ＂large power supply with small load＂, and through the measures such as improving material quality, retrofitting structure of parts, and corresponding of working principle with working property etc. The principles, structure, characteristics and contrast of the 13 kinds of energy saving transformer were introduced including super conduction, amorphous, rolled core, R type core, three-dimension core, single-phase pole-mounted, capacity-adjustable, on load voltage regulation, dust clearing of medium impedance, electricity saving device of low voltage, loss ratio matching of copper and iron, adopting silicon steel sheet with thin magnetic domain and high magnetic conductivity and wire of low resistance and loss. As the measures are combined, energy saving can be more. The demonstration points out that the loss ratio of S7, S9, S11 series is suitable for work in one shift, and not for continuous and rural load.
