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。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.
