Generally speaking, uninterrupted power supply can be divided into three categories according to its different working methods: backup, online and on-line interactive. The backup uninterrupted power supply operation is simple: when the power is normal, electricity will be provided directly to the computer equipment; when the utility power is disconnected, battery uninterrupted power supply inverter to the computer and other equipment power supply. That is to say that in most of the time is by city electric equipment for power supply, so the backup uninterrupted power supply for city power network exists on the surge, peak, frequency offset can be eliminated. But the uninterrupted power supply backup power capacity is small, but it has the advantages of simple technology, low cost, cheap price, and it will be suitable in voltage stability occasions.
The Daily Work of Uninterrupted Power Supply
In their daily work, should be familiar with their use of cell type, it has the basic characteristics and performance. It can guide us to correctly use and maintenance, have very important sense, to extend the service life of the battery is very important. When charging, the best control in 10 ℃ temperature 30 ℃, right above 30 degrees C best to take measures to cool down the battery, to avoid overheating deformation; And the room temperature below 5 degrees Celsius, will cause the charge is insufficient, affect the service life of the battery.
The species of Uninterrupted Power Supply
The Uninterrupted Power Supply classification methods varied, according to the power size can be divided into large and medium-sized mistress power capacity; the output waveform can be divided into square wave, trapezoidal wave or sine wave; according to the input and output can be divided into single phase into single-phase, three-phase to single-phase or three-phase to three-phase; according to the work principle can also be divided into dynamic Uninterrupted Power Supply and static Uninterrupted Power Supply two categories. Dynamic ups backup power is dependent on inertial flywheel stored energy to maintain the load power supply continuity, the uninterruptible power supply with heavy, large noise, low efficiency, long switching time and other shortcomings, has been replaced by a static uninterruptable power supply. Static Uninterrupted Power Supply to batteries as the energy storage tool, city normal AC power is rectified into a DC electrical and electrical energy stored in the batteries, when the utility power is cut off by the inverter will be stored in the storage battery DC power into AC power to maintain power to the load. According to the different working modes, static Uninterrupted Power Supply can be divided into the backup Uninterrupted Power Supply, on-line Uninterrupted Power Supply, on line interactive Uninterrupted Power Supply and Delta transformation Uninterrupted Power Supply four kind of types.
