摘要
建筑电气系统的接地装置的好坏直接关系到整个建筑电气系统设备的安全和正常运行。评价接地网的性能时主要考虑两个参数,接地阻抗和接地网电气完整性。讨论了接地电阻、接地网完整性的测试及实例,提出了接地电阻测试在准确性方面有待解决的问题,以及工程中接地网完整性不合格的整改方法。
The quality of grounding equipment can relates directly to the security and normal operation of the construction electrical system.When we evaluate the performance of grounding grids,we mainly consider two parameters,grounding impedance and completion of electrical grounding.This article discusses tests and examples referring on the completion of grounding impedance and grounding grids.It also proposes unresolved problems to the accuracy of grounding resistance test and improving methods to the unqualified grounding in project.
