| Abstract: | The safety protecting device of model DB 1 electrical system is a new kind of multifunctional double action safety device which can be used in the system of power supply and electric apparatuses. When it is used in the 220 V circuit with an industrial frequency alternating current,it can give good protection against overvoltage,under voltage,interference of strong current,thunder and lightning,electric shock,electric leakage,electric wire fire and circuit fire.In particular,it has the function of power supply delay and the function to protect expensive important electric apparatuses from damage.Its control circuit,which has been designed on the basis of functional modular block,can be combined flexibly according to different needs.The safety device is very convenient and reliable in application. |
