How to install the Ireland AC power supply so that it can function as a protection switch?(3)

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/buck 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.

Drive module power supply
The frequency converter power supply is mainly used for the frequency conversion and speed regulation of the AC motor. The main circuit of the inverter power supply adopts the AC-DC-AC scheme. The power frequency power supply becomes a fixed DC voltage through a rectifier, and then a PWM high-frequency converter composed of high-power transistors or IGBTs inverts the DC voltage into an AC output with variable voltage and frequency. The output waveform of the power supply is similar to a sine wave. It is used to drive the AC asynchronous motor to realize stepless speed regulation.

During operation, it can track and detect the Ireland   Marine boost/buck voltage power supply voltage, neutral line disconnection, phase loss / disconnection, etc., and cut off the Marine boost/buck voltage power supply in time when a fault occurs, making it safer and safer to use electricity. More reliable; at the same time, through a set of attached indicator lights, it shows the fault situation, which provides convenience for line maintenance.

Ireland It can be widely used in electrical equipment protection stations, meteorological telemetry stations, energy pipeline telemetry stations, petroleum Exploration, automatic pumping and other places.
