一起10kV开关柜异常声音的原因分析及解决方案

Cause Analysis and Solution of an Abnormal Sound in 10kV Switchgear

针对某开关站10 kV开关柜在正常运行期间产生异常声腔音的原因进行分析,系统内由于现场无功补偿装置的选型及配置不合理等原因而引起的异常声音和系统谐振,通过对现场无功补偿装置的选型及配置的分析,对该开关站的电能质量进行检测,提出了具体的异常声音改进治理措施,解决了由于系统谐振使开关柜产生了异常声音的问题。

This paper analyzes the causes of an abnormal sound in a 10 kV switch cab⁃inet during normal operation.The abnormal sound and system resonance were caused by un⁃reasonable selection and configuration of on-site reactive power compensation device in the system.Through analysis of the selection and configuration of on-site reactive power compen⁃sation device,the power quality of the switch station was inspected,and specific measures for improving the abnormal sound were put forward,which solved the problem of switch cab⁃inet producing abnormal sound due to system resonance.
