Problems solved by technology

The design idea of ​​the intrinsically safe power supply is to stabilize the input power so that the output power will not mutate with the instantaneous mutation of the input voltage and affect the electrical equipment at the back end. Most of the existing intrinsically safe power supplies are for the DC section of the back end. Do voltage stabilization processing, but when the

Abstract

The invention provides a magnetic-saturation intrinsically-safe power supply. The power supply comprises an alternating current power supply input module, a rectifying and filter circuit module, a voltage regulating circuit module and an intrinsically-safe power supply output module which are electrically connected sequentially. The power supply is characterized by also comprising a magnetic-saturation voltage stabilizing circuit module which is electrically connected between the alternating current power supply input module and the rectifying and filter circuit module. The magnetic-saturation intrinsically-safe power supply is good in voltage output stability, wide in voltage stabilizing range, high in reliability, capable of improving the voltage stabilizing effect further so as to achieve explosion-isolation and explosion-proof effects and particularly suitable for power supply to electrical devices in hazardous environments with explosive or flammable gases, steam, liquids and the like.

Description
