摘要:
海南三亚有轨电车示范线的有轨电车充电装置在恒压充电过程中频繁发生输出过电压故障。对输出电压进行实测，并对过电压原因展开分析。分析发现：在充电装置充电末期，一旦超级电容端电压超过821 V并持续10 s，就会触发故障保护，高速断路器保护断开。通过分析定位过电压产生原因，最后提出解决建议。
Abstracts:
Since the over-voltage failure frequently occurred in constant voltage charging process of the charging device, which is installed in trams on Sanya Demonstration Line in Hainan Province, the output voltage is measured and the causes of over-voltage are analyzed. According to the analysis, at the charging end of the device, when the super capacitor terminal voltage is over 821 V for 10 s, the fault protection will be triggered and the high-speed breaker protection be disconnected. After detection of the over-voltage causes, solutions are proposed accordingly.
