摘　　要：结合某110 kV变电站35 kV开关柜绝缘缺陷案例,采用局部放电检测方法证实了该开关柜存在局部放电问题,并采用紫外成像技术对缺陷进行定位,最后根据定位结果提出了开关柜绝缘改造方案。研究结果表明,通过局部放电检测能够有效地发现设备内部存在的放电缺陷,为绝缘改造提供可靠依据。Combined with a case of insulation defects in a 35 kV switchgear in a 110 kV substation,the partial discharge detection method was used to prove that the switchgear had partial discharge problems.The ultraviolet imaging technology was used to locate the defects.Finally,the insulation modification plan of the switchgear was proposed based on the location results.The research results show that the partial discharge detection can effectively find the discharge defects inside the equipment and provide a reliable basis for insulation modification.
