大型高电压铝电解电容器早期失效的探讨

Discussion on Early Failure of Large High Voltage Aluminum Electrolytic Capacitors

从目前的发展趋势看,全球范围内的铝电解电容器供应市场逐步完善,国内的生产供应技术已经在世界范围内名列前茅,尤其在日本产量萎缩减少的情况下,中国企业面临巨大的竞争机遇。在上行压力、下游需求的影响下,大型高电压铝电解电容器的生产量逐步提升,但依旧面临早期失效问题,包括击穿、短路、压力阀释放等。这些问题会影响高电压铝电解电容器的使用寿命与安全,需要采取有效的解决措施,本文就此进行了相关的阐述和分析。

From the current development trend,the global aluminum electrolytic capacitor supply market is gradually improving,and the domestic production and supply technology has been among the best in the world.Especially in the case of shrinking output in Japan,Chinese enterprises are faced with huge competitive opportunities.Under the influence of upstream pressure and downstream demand,the production of large high-voltage aluminum electrolytic capacitors has gradually increased,but they still face early failure problems,including breakdown,short circuit,pressure valve release,etc.These problems will affect the service life and safety of high voltage aluminum electrolytic capacitors,and effective measures need to be taken to solve them.
