摘　　要：干式空心电抗器能够改善电力系统电能质量、提升电流稳定性,但在工作时漏磁较大,对周围环境造成不良影响。为解决电抗器漏磁过大的问题,本文提出一种新型多单元串并联环形低漏磁电抗器拓扑结构,在进行原理分析的基础上,对试品分别进行工频耐压试验、温升试验、雷电冲击试验和最大短时电流试验,结果表明该试品性能达到了相关国家标准要求,能够应用于实际电网中。The dry-type air-core reactor can improve the power quality of the power system and improve the current stability, but the magnetic flux leakage is large during operation, which will cause adverse effects on the surrounding environment. To solve the problem of excessive magnetic leakage of the reactor, this paper proposes a new type of multi-unit series-parallel toroidal low-leakage magnetic reactor topology. Based on the analysis of the principle, the power frequency withstand voltage test,temperature rise test, lightning impulse test and maximum short-time current test are carried out respectively. The test results show that the performance of the test product meets the requirements of relevant national standards and can be applied to the actual power grid.
