三、正确掌握使用变压器保护设备 为了防止变压器在运行中发生故障,造成设备的严重损坏和对供电系统带来影响,变压器运行时必需设有各种保护设备。保护设备的种类有: (一)低压侧的过电流保护。作用为防止负荷侧产生过电流,侵入变压器内部造成变压器过电流,甚至穿越变压器造成一 Third, the correct grasp of the use of transformer protection equipment In order to prevent transformer failure in operation, resulting in serious damage to the equipment and the impact on the power supply system, transformer operation must be equipped with a variety of protective equipment. The types of protection equipment are: (A) low-voltage side of the over-current protection. The role of the load side to prevent over-current, invade the transformer internal transformer over-current caused, or even through the transformer caused by a
