How to install the Mongolia 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 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 Mongolia Marine boost voltage power supply voltage, neutral line disconnection, phase loss / disconnection, etc., and cut off the Marine boost 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.
HVDC module power supply
High-power switching high-voltage DC power supplies are widely used in large-scale equipment such as electrostatic dust removal, water quality improvement, medical X-ray machines and CT machines. The voltage is as high as 50~159kV, the current reaches more than 0.5A, and the power can reach 100kW.
Since the 1970s, some Japanese companies have begun to use inverter technology to rectify the mains and invert it to an intermediate frequency of about 3kHz, and then boost it. In the 1980s, high-frequency switching power supply technology developed rapidly. Siemens of Germany uses power transistors as the main switching elements to increase the switching frequency of the power supply to above 20kHz. And the dry-type transformer technology is successfully applied to the high-frequency high-voltage power supply, the high-voltage transformer oil tank is cancelled, and the volume of the transformer system is further reduced.
Mongolia It can be widely used in electrical equipment protection stations, meteorological telemetry stations, energy pipeline telemetry stations, petroleum Exploration, automatic pumping and other places.
