摘　　要：电力线通信中电压瞬变的强大破坏能力及其出现的时间、位置无法预测,不仅使数据瞬间乱态、丢失,严重制约了高速数据的传输,还会导致电子产品的损坏。因此,电压瞬变防护问题已经得到越来越多设计者的重视。文章在指出防护的必要性的同时,还介绍了浪涌的产生和抑制技术,并重点介绍了两种满足高速电力线通信的浪涌抑制方法。The powerful damage and unpredictability of transient voltage in power line communication not only leads to data chaos, but also seriously restricts high data speed in power line and destroys electric apparatus. Therefore, designers pay more and more attention to protection apparatus from transient voltage. This thesis points out the necessity of transient voltage protection, and introduces the emerging and protection methods that suffice high data transmission in power line communication.
