摘要
介绍了电流上升率和电流增量2种保护的原理,以广州地铁一号线使用的3UB61保护装置为例,详细叙述了2种保护进行试验的原理和方法。实践证明,在对这2种保护的校验中,将原先的定性分析上升到定量分析的试验方法具有重要实际意义。
It introduces the theory of the rate of rise of current protection and current increment protection, uses 3UB61 protector on Guangzhou metro line 1 as an example, recounts the testing theory and method of these two protectors into particulars. It proves the testing method of these two protectors we applies from qualitative analysis to quantitative analysis has important practice meaning.
