How to install the Palestine 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.

During operation, it can track and detect the Palestine   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.

Power active filter is a new type of power electronic device that can dynamically suppress harmonics. It can overcome the shortcomings of traditional LC filters and is a promising harmonic suppression method. The filter consists of a bridge switching power converter and a specific control circuit. The difference from the traditional switching power supply is: (1) not only feedback the output voltage, but also feedback the average input current; (2) the current loop reference signal is the product of the voltage loop error signal and the full-wave rectified voltage sampling signal.

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