TN系统中等电位联结对降低接触电压定量分析

Quantitative Analysis of Equal Potential Bonding Decreasing Contact Voltage in TN System

结合实际工程实例,分析了TN系统中不同等电位联结方式对降低接触电压的影响。提出建筑电气设计中总等电位联结可以更多地降低接触电压,减少保护电器动作的不可靠性,确保电气系统的可靠性和安全性。

Combining by the aetural engineering case, this paper analyzed the effect on decreasing the contact voltage at different equalpotential bonding modes in TN system. It is pointed out that the main equalpotential bonding can more decrease the contact voltage value, and reduce the action unreliability of protective device, which ensures the reliability and security of electrical system.
