悬浮导体感应电压的估算及对策
Estimation and Countermeasures of Floating Conductor Induced Voltage
摘要
Abstract
A floating conductor below the direct current (DC) transmission lines will produce certain induction voltage and the human body would be affected by transient shock when contacting the conductor.In order to estimate the induction voltage,the total electric field under DC lines is obtained by the Deutsch-based numerical calculation method,and the potential of floating fine conductors in the nominal electric field under DC lines is gotten by the charge simulation method,For the purpose of engineering simplification,a method is proposed for estimating conductor induction potential in the total field by multiplying the potential of floating fine conductors with the potential proportion coefficient.Finally measures are proposed to reduce the induced voltage of floating conductors.关键词
