摘要
针对电磁开关和电力电子开关投切电容器无功补偿装置应用中存在的问题,开发、研制了一种基于复合开关投切电容器的无功补偿装置。采用三相共补Δ接线与单相分补Y接线相结合的接线方式,实现了对三相负载分相、分级、快速的无功补偿。试验和现场运行情况表明,这种无功补偿装置运行可靠性高、性能稳定,能满足绝大多数场合的应用需要。对复合开关的组成原理、电路结构和装置的整体性能等进行了详细描述。
Aiming at the disadvantages in the application of reactive power compensation device with electromagnetic or power electronic switches for pulling in or out the capacitor,a reactive power compensation device based on the compound switch ,which can realize grading and fast compensation for each phase using both delta and star connection capacitor,is developed to switch capacitor.The test results and cite operation show that this device with high reliability and stability can meet the application demands of almost all situations.This paper describes the principle,circuit structure of compound switch and overall performance of the device in detail.
