如图2所示,所述浪涌保护器是一种端口并联形式的电涌保护电路,包括由两个内含温度保险丝的氧化锌压敏电阻TMOV1、TMOV2以及一个二级气体放电管G1组成的单相平衡电路。两个氧化锌压敏电阻TMOV1、TMOV2串联后并接在电源插头的相线L和中性线N之间,组成差模保护电路,保证线间残压;二级气体放电管G1的一脚连接在两个氧化锌压敏电阻TMOV1、TMOV2之间的中点位置,另一脚与电源插头的地线PE连接,形成两组共模保护电路,其中氧化锌压 敏电阻TMOV1与二级气体放电管G1串联形成一组共模保护电路,氧化锌压敏电阻TMOV2与二级气体放电管G1形成另一组共模保护电路。  As shown in Figure 2, the surge protector is a surge protection circuit in the form of port parallel connection, which consists of two zinc oxide varistors TMOV1 and TMOV2 with built-in thermal fuses and a secondary gas discharge tube G1 single-phase balanced circuit. Two zinc oxide varistors TMOV1 and TMOV2 are connected in series and connected between the phase line L and the neutral line N of the power plug to form a differential mode protection circuit to ensure the residual voltage between the lines; one leg of the secondary gas discharge tube G1 Connected at the midpoint between the two zinc oxide varistors TMOV1 and TMOV2, and the other pin is connected to the ground wire PE of the power plug to form two sets of common mode protection circuits, in which the zinc oxide varistor TMOV1 is connected to the secondary gas The discharge tube G1 is connected in series to form a set of common-mode protection circuits, and the zinc oxide varistor TMOV2 and the secondary gas discharge tube G1 form another set of common-mode protection circuits. the
