【摘要】 干式空心电抗器安装的相间距通常为1.7倍电抗器外径（1.7D），当安装距离缩小时，电抗器周围磁场强度会发生变化从而影响其电气参数。本文以小型串联电抗器为例，采用仿真计算与实测相结合的方法，研究水平布置电抗器相间距与性能参数之间的关系。结果表明，相间距在1.3D～1.7D范围内时，虽对小型电抗器的技术参数有影响，但未使其超出标准允许范围。更多还原

【Abstract】 The inter-phase distance of dry-type air-core reactor is usually 1.7 times the outer diameter(1.7D). When the installation distance is reduced, the performance parameters of the reactor will be affected due to the change of surrounding magnetic field strength. The relationship between inter-phase distance and performance parameters of horizontally arranged reactors is studied by combining simulation calculation with actual measurement. It is concluded that although the inter-phase distance has an impact on the performance parameters of small reactors in the range of 1.3D to 1.7D, the performance parameters do not exceed the allowable range of the standard.更多还原
