Abstract

一种高压保护电路包括：主继电器（K1）、辅助继电器（K2）、第一电阻（R1）、第二电阻（R2）、第一电容（C1）和第二电容（C2）；所述主继电器（K1）一端连接至火线的输入端口，另一端连接至火线的输出端口；所述辅助继电器（K2）—端连接至火线的输入端口，另一端连接在所述第一电阻（R1）和第二电阻（R2）之间；所述第一电容（C1）的一端连接至火线的输出端口，另一端连接至与火线并行的零线；所述第二电容（C2）并接于主继电器（K1）两端；所述第二电阻（R2）和第一电阻（R1）依次串联于火线的输入端口与输出端口之间。本发明还公开了一种高压保护方法及包括上述高压保护电路的电源。本发明通过在主继电器（K1）两端跨接第二电容（C2），通过调节第一电容（C1）和第二电容（C2）的电容值，可有效解决节能模式下不能快速恢复的问题，使系统实现高效节能，并保证在节能模式下的高压保护。
