资料介绍

为了缓解电压偏移对变压器造成的硬性损伤,提出一种基于电子开关的配电变压器有载调压方法。利用电子开关的分接形式连接阻容吸收电路,以此为条件启动配电接触器,完成配电变压器的调压执行机构组成分析;根据完整的RC电子开关选型结果,完成连续无触点的有载调压及分级无触点的有载调压,实现配电变压器的有载调压。对比实验结果表明,与无弧化调压技术相比,应用基于电子开关的配电变压器有载调压方法后,配电变压器的调压绕组能力得到明显提升,过渡电压的实段波值也不再呈现直线攀升状态,由电压偏移造成的变压器硬性损伤问题得到了有效解决。

In order to alleviate the hard damage caused by voltage offset to the transformer,an on-load voltage regulation method for distribution transformer based on electronic switch is tap changer circuit is connected by the tapping form of the electronic switch,and the power distribution contactor is activated as a condition to complete the composition analysis of the voltage regulating actuator of the distribution transformer;according to the complete RC electronic switch selection result,the continuous non-contact is on-load voltage regulation and grading non-contact onload voltage regulation realizes the on-load voltage regulation of the distribution experimental results show that compared with the non-arcing voltage regulation technology,after applying the load regulation method of the distribution transformer based on the electronic switch,the capacity of the voltage regulating winding of the distribution transformer is obviously improved,and the real wave value of the transition voltage is also The straight-line climbing state is no longer present,and the hard damage problem of the transformer caused by the voltage offset is effectively solved.
