摘　　要：根据电磁暂态程序——ATP建立仿真模型,计算和分析750 kV同塔双回输电线路间的感应电压和感应电流。为了检验接地开关的分断能力,利用ATP计算接地开关的稳态感应电压和瞬态恢复电压,并以一800 kV接地开关为对象进行开断容性电流和感性电流的试验。ATP仿真结果和试验结果表明,该800 kV接地开关可适用于750 kV同塔双回输电线路。According to electro-magnetic transient program ATP, this paper establishes a simulation model, calculates and an- alyzes induced voltage and current of 750 kV double-circuit transmission line. For examining disjunction of grounding switch, it carries out tests for switching capacitive current and reactive current by using ATP to calculate steady state induced voltage and transient recovery voltage of grounding switching and taking one 800 kV grounding switching as an object. ATP simulation result and testing result show that this 800 kV grounding switching is suitable for 750 kV double-circuit transmis- sion line.
