How to install the Saudi Arabia 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.
(3) Before the installation is completed and the power is turned on, the wiring on each terminal should be checked and checked again to ensure that the input and output, AC and DC, single-phase and multi-phase, positive and negative, voltage and current values are correct. Prevent the occurrence of reverse and wrong connections.
(4) For high-power power supplies, there are generally two or more "+" output terminals and "-" output terminals. In fact, they belong to the same output electrode, but for the convenience of user wiring, they are connected together internally.
(5) The module power supply is not allowed to work at full load for a long time. The utilization rate of linear power supply should be controlled within 60%; the utilization rate of switching power supply should be controlled within 80%, otherwise it may cause early artificial failure of module power supply.
During operation, it can track and detect the Saudi Arabia 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.
Saudi Arabia It can be widely used in electrical equipment protection stations, meteorological telemetry stations, energy pipeline telemetry stations, petroleum Exploration, automatic pumping and other places.
