室内并联补偿电容器组不宜串联空心限流电抗器

The Hollow Reactors Shouldn't be Chosen to be in Series with Large Capacity Shunt Capacitor Indoor

针对现场出现电抗器杂散磁场而使周围护栏发热的实际问题,分析并通过小型试验证明空心电抗器不可能通过调整线圈绕向消除(或减弱)竖直叠装时的“杂散磁场”,提出了以后设计室内并联电容器组串联限流电抗器时,不宜应用空心电抗器,而仍以采用油浸式铁心电抗器较好的观点。

According to gnardrail＇s exothermic problem arisen from reactor＇s stray magnetic field on site, the paper briefly analyzed that hollow reactors can＇t eliminate or weaken the stray magnetic field through adjusting their coils＇ wrapping direction when they were apeak fixed, and this analysis were proved through minitype simulation test. The paper brought forward the point that the hollow reactors shouldn＇t be in series and oil immersed type reactors should be chosen to connect with shunt capacitor indoor henceforth.
