COMMAND AND PROTECTION AGAINST SUB AND ABOUT VOLTAGE FOR LOW VOLTAGE RESIDENTIAL AND COMMERCIAL SINGLE-PHASE POWER SUPPLY

摘要

Control and protection against undervoltage and overvoltage for low voltage residential and commercial single-phase mains The present invention of a control and undervoltage protection and overvoltage for single-phase residential and commercial low voltage mains is provided with an emergency circuit. For home there is a fault in the single-phase voltage supervision relay it will be activated until the fault is repaired and this system aims to protect the electronic equipment against voltage surges and thereby increasing their service life. the equipment is composed of electronic and electromechanical components according to the pvc control box drawing with the "signaling drawing" signs, layout drawing of the components in the pvc box "layout drawing", block diagram of the first stage circuits, circuit alarm and emergency actuation, 1 'diagram - 1', electrical surge protection 'diagram - 2', power circuit diagram 'diagram - 3', main stage diagram, 'diagram - 4', emergency, "diagram - 5", first main stage diagram and emergency circuit, "diagram - 6".
