摘要
10 kV复合外套避雷器在电力系统中有着较庞大的应用数量,而大电流耐受能力是制约复合外套避雷器应用的重用因素。对10 kV复合外套避雷器开展整只4/10μs、65 kA大电流冲击耐受试验,并对试验结果进行分析,得出生产工艺与大电流冲击耐受能力存在密切关系,因此在非电阻片因素下对生产工艺进行改进,从而最大程度提高其大电流冲击耐受能力。
10 kV composite sheathed arresters have a relatively large number of applications in power systems,and the large current withstand capability is a factor restricting the reuse of composite sheathed arresters.In this paper,a whole 4/10μs,65 kA high-current impulse withstand test is carried out on the 10 kV composite sheathed arrester and the test results are analyzed.It is concluded that the production process is closely related to the high-current impulse withstand capability.Therefore,the production process is improved under the non-resistor factor,so as to maximize its high current impact tolerance.
