Compressors Used Three Phase Voltage Monitoring Relay 1-25s time delay protector
All electric appliances are very sensitive when using the grid voltage is too high too low, whether industrial equipment or household appliances have a rated voltage, the voltage range is usually specified as 170V-240V (can be seen on the nameplate or instructions of the electrical equipment). If this voltage is exceeded, the insulation strength and pressure resistance of the electric appliance are exceeded, and the electric appliance will thus generate heat, breakdown and burn or even cause a fire. At present, due to the theft of the zero line, aging equipment, technical failures, human failures, natural disasters, power outages, and other reasons, the voltage instability, the voltage is too low, resulting in a large number of electrical appliances are burned out and burned in large areas, People have suffered heavy losses, no claims, and labor and people’s misfortune have come one after another. Yimin’s overpressure, overpressure, and undervoltage protectors (also known as electrical protectors) should be added to prevent electrical fires and protect the safety of lives and property.
The state provides that the single-phase 220V power supply error shall not be greater than or equal to 10% of 220V, that is, when 220V is over 242V, it is called overvoltage; below 198V, it is called undervoltage. In the single-phase 220V power supply, 220V suddenly rises to 380V or 440V ultra high voltage, which is called overvoltage; when the grid voltage suddenly changes overvoltage, overvoltage and undervoltage, the device that can automatically cut off the power quickly and intelligently is called overvoltage. Overvoltage and undervoltage protectors.
