Analysis and Disposal of a 10 kV Zinc Oxide Arrestor
Regarding the fault of a 10 kV zinc oxide arrester,first,through visual inspection,routine test detection,and test anal-ysis of disassembling key parts,problems such as poor sealing,defects in process design,and unqualified valve plates were found.Then,spot checks and analysis were carried out on the inventory(in-service)equipment,and the fault mechanism of the arrester was discussed.It was concluded that the sealing performance of the arrester,the compactness of the equipment's process design,and the quality of the internal valve plates are the key factors affecting the overall operating performance of the equip-ment.Finally,improvement suggestions were put forward in terms of arrester selection,daily operation and maintenance,and ar-rester installation,which will undoubtedly promote the continuous improvement of equipment quality and ensure reliable power supply for users.
