可移动高压大容量链式STATCOM系统集装箱结构
摘要：
可移动高压大容量链式STATCOM系统集装箱结构，包括：两个并联的链式STATCOM系统，每个系统，包括三相链式H桥功率单元组，每单元组包括串联的若干个H桥功率单元，再加上两端各一个电抗器，每单元组安置在一个阀组集装箱中，每单元组的两个电抗器上下放置，安置在集装箱外，两个并联系统可分别通过QF1和QF2两个高压开关与35kV电网直挂；链式STATCOM系统集装箱共7个，6个为阀组集装箱，1个为控制集装箱。本实用新型造价低、散热好，方便不同电压和不同容量的STATCOM批量生产，且结构紧凑，安装、调试、维修、拆卸及运输都相当放便，野外放置安装简单，还便于功率扩展和安全运行，可满足大容量装机需要。
摘要（英）：

A removable high-voltage high-capacity chained STATCOM system container structure comprises two parallel chained STATCOM systems. Each system comprises three-phase chained H bridge power unit groups. Each unit group comprises several series-wound H bridge power units with one electric reactor disposed at two ends of each unit group. Each unit group is arranged in a valve group container. Two electric reactors of each unit group are arranged up and down and disposed outside the containers. The two parallel systems can be directly suspended on 35kV power grid respectively through two high-voltage switches of QF1 and QF2. There are seven chained STATCOM system containers, six of which are valve group containers and one of which is a control container. The removable high-voltage high-capacity chained STATCOM system container structure provided by the invention has advantages of low construction cost and good heat dissipation, is convenient for batch production of STATCOM of different voltages and different capacities, has a compact structure, is very convenient to install, debug, maintain, dismantle and transport, is simple to install when placed outdoors, is also convenient for power scaling and safe operation, and can satisfy high-capacity installation requirements.
