对电力变压器瓦斯保护的理解

摘要

电力系统运行的可靠性越来越受到重视，电力变压器作为电力系统中的重要电气设备，现目前的特点是电压等级高、容量大且造价十分昂贵，其故障会对电力系统的安全稳定运行带来严重的影响。因此应根据变压器容量和重要程度装设性能好，可靠性高的保护装置。其中瓦斯保护属于主保护。%The operation reliability of power system more and more attention, power transformer power system as the important electrical equipment, is now characterized by high voltage, large capacity and t, he cost is very expensive, its fault in power system safe and stable operation to bring serious effect,. So it should be based on the transformer capacity and important degree equipped with good performance, high reliability of protection device. The gas protection of main protection.
