| 摘 要： | 为验证某制造厂新型自动调谐消弧线圈装置性能,笔者进行了消弧线圈成套装置金属接地、电阻接地、弧光接地等现场试验,结果发现,当电网具有较高谐波时,单相接地电流含有丰富的谐波成分,消弧线圈并不能补偿谐波接地电流,造成以谐波为主的残流值超标,影响补偿效果,对此问题应引起关注。

| Abstract: | In order to test the performance of new type automatic tuning arc-suppression coil of some factory,the metal grounding、 resistance grounding and arc grounding test of arc-suppression coil whole set tests were carried out.By analyzed the test result,abundant harmonic component was discovered in single-phase grounding current when power grid have more harmonics,and arc-suppression coil can not compensate for harmonic grounding currents.This will cause harmonic residual grounding current exceed the standard value,compensation effects be affected.It needs more attention to this question. |
