摘要
通过定量分析,论述了三相四线制供电系统中中性线的重要作用;强调指出,若要保证三相相电压在允许的电压范围内,必须使中性线连接完好,电压偏移在允许的范围内;并利用PSPICE仿真,说明了中性线阻抗变化对中性点电压偏移的影响,从而提出了保护措施。
Based on quantitative analysis,the key role of neutral line in the three-phase and four-wire power supply system is discussed.It is emphatically indicated that if the three-phase phase (voltage) within the range permitted is ensured,the neutral line must be well joined and the deviation of (voltage) is within the range permitted.By applying PSPICE to imitate the real situation,the influence of the change of impedance of the neutral line on the deviation of voltage at neutral point is given,and then the protective measures are put forward.
