摘　　要：文中对国家标准《GB 1984—2014高压交流断路器》及《GB/T 4473—2008高压交流断路器的合成试验》、国际短路试验联盟STL导则中关于三相全电压关合的内容进行了解读,通过对直接试验回路中三相全电压关合过程进行模拟明确关合过程中断路器两端电压和电流波形的变化,对两种合成关合试验回路进行模拟分析并比较,提出了一种便于实现且等价性较好的三相全电压关合试验回路。结果表明该回路与目前标准推荐回路相比,实现难度较小,笔者推荐实验室可选择该试验回路。This article analyzed the content about three phase full voltage making test in ＂GB 1984--2014 High- voltage alternating circuit-breaker＂, ＂GB/T 4473-2008 Synthetic testing of high-voltage alternating circuit-breaker＂ and ＂STL guide＂. According to the analysis, this article compared two test circuits for three phase full voltage making test depending on the simulation of voltage and current waveform during the short-circuit making process in direct test circuit. In the conclusion, this article puts forward a test circuit which is easy to implement and has a better equivalence for three phase full voltage making test. The results show that the circuit is less difficult than the current standard recommended circuit, and the laboratory can choose the test circuit.
