开放式空心试验电抗器的设计研究

Design Research on Open-Type Air-Core Test Reactor

电抗器在低电压穿越测试装置中起到阻抗分压作用,对一种开放式空心电抗器的设计方法进行研究。介绍了该电抗器的电感计算、绝缘设计和温升计算,基于VB软件编制了电感计算程序,使用Maxwell软件对电感和损耗进行了仿真验证。实测结果表明,样机电感偏差小,顺利通过绝缘试验,温升略高于设计值,能满足工程需求。

The reactor plays the impedance and partial pressure part in low voltage ride through test device. This paper carried out re-search on the design method for a kind of open-type air-core test reactor. Introduction was made to its inductance calculation, insulation design and calculation of temperature rise. This paper compiled the software of inductance calculation based on VB and carried out simu-lation verifcation for the inductance and coil loss by Maxwell. The actual measurement result shows that the prototype has a little bias inductance, sweeping through insulation test with a little higher temperature rise than the designed value, which meets the engineering requirement of the project.
