摘　　要：针对电力行业经常使用的AC 220 V电源2种浪涌保护方案,从方案中所用的元器件特性、优缺点、方案在标准测试下的试验现象和残压等方面进行比较,最终确定在电源L对地和N对地之间分别接入气体放电管和压敏电阻,在L和N之间接入压敏电阻为最佳方案,对后续电源端口浪涌防护方案的选取具有一定参考作用。Two surge protection measures of AC 220 V power supply often use in the power industry,and compare the characteristics,advantages and disadvantages of the components used in the scheme.The test phenomenon and residual voltage of the scheme under the standard test.Finally,it is determined that the best scheme is to connect the gas discharge tube and metal oxide varistors separately between the power L and N to the ground.Connecting varistor between L and N is the best scheme,which plays a reference role in the selection of surge protection schemes for subsequent power ports.
