摘　　要：在电气设计中,电气安全净距的选择对电气运行可靠性及工作人员的安全至关重要。DL/T 5352—2006《高压配电装置设计技术规程》仅给出了几个常规电压等级下的安全净距,当设计电压变化时,无法从规程中直接选出安全净距。通过对比国内标准和国际标准,探讨了电气最小安全净距和最小电气安全距离的关系,从而得到电气安全净距的计算方法。In the electrical design,the selection of the electrical safety clear distance has important impact on the reliability of electrical operation and the safety of working personnel.In the file DL/T 5352—2006'Technical Code for Designing High Voltage Electrical Switchgear',only the safety clear distances for several conventional voltage classes were given.When the designed voltage is changed,it is unable to select the safety clear distance from the technical code directly.According to the comparison of the domestic standard with the international standards,the relation between the minimum electrical clear distance and the minimum safety distance was discussed,and the computing method of electrical safety clear distance was obtained.
