How to install the Austria AC power supply so that it can function as a protection switch?(2)

Austria The three-phase AC power intelligent protector has major electrical fault protection functions such as overvoltage, low voltage, neutral wire disconnection, short circuit, phase loss/opening, etc., and has fault identification, fault indication, voltage before closing, neutral live wire reverse connection, Zero line disconnection, phase loss/phase failure detection, remote monitoring, online parameter modification and software upgrade functions.

The size of the magnetic components is closely related to the switching operating frequency. Within the allowable operating frequency range of the magnetic components, the size of the magnetic components is inversely proportional to the switching operating frequency. To reduce the high-frequency switching transformer and inductance of the module switching power supply The volume of magnetic components and other magnetic components need to increase the switching frequency.

The three-phase AC power intelligent protector has developed and created the function of "fault detection before closing", which has greatly improved its performance and reliability. The three-phase AC power intelligent protector detects the Marine boost voltage power supply voltage, the reverse connection of the neutral line, the disconnection of the neutral line, and the lack of phase/phase failure through the single-chip microcomputer before the main switch is closed.
