高压交流断路器电寿命试验方法探讨

Investigation on Testing Methods of Electrical Endurance for HV Alternating - Current Circuit Breakers

文章解释了高压交流断路器电寿命的含义,介绍了IEC62271-100、GB 1984-2003和DL 402-1999标准中断路器电寿命试验方法的规定。通过对比国内外的试验方法、分析电寿命试验对断路器生产和用户的意义,提出了对我国国家标准和电力行业标准中40.5 kV及以下电压等级的E2级断路器规定的修改建议。

The definition of electrical endurance of HV alternating - current circuit breakers is interpreted, and the testing methods specified in IEC62271 - 100, GB1984-2003 and DL402-1999 are illustrated in this paper. By comparing the testing methods of some countries and analyzing the influences of electrical endurance tests on circuit - breaker production and users, the revision of testing methods of class E2 circuit breakers is suggested for national standard and electric power industry standard in China.
