说明：  本高压脉冲式电子围栏设计主要采用高频脉冲，进行开关式充放电使得磁环次级的电压升高，用4倍压电路再次升高电压，次电路可以得到5KV-10KV电压，是人的触感强烈，但是不会伤害人体。
(The high voltage pulse type electronic fence design mainly adopts high frequency pulse, to switch type charging and discharging the circular and the secondary voltage rise, voltage doubler circuit to rise again in 4, times of circuit can get 5 kv and 10 kv voltage, is a person feels intense, but won't harm the body.)
