UPS manufacturers Interpret three types of use skills of uninterruptible power systems. For uninterruptible power supply, most people have awareness, it is important to continue power supply for computer network systems, in power outages, and prevent data loss. In the daily use, in order to ensure the service life of the power supply, it is also critical to the relevant use skills at the same time.
UPS manufacturers Interpretation of the three types of use skills of uninterruptible power systems UPS is divided into rear preparation in work principle, online interactive formula three categories. First, the rear pre-pre-preparative uninterrupted power system use skills 1, can not increase the fuse capacity inverter, have overloaded and short-circuit automatic protection function, but when power is supplied, it is generally overloaded. Task, users can easily increase the capacity of the main electric input fuses, once the UPS outputs short circuit accidents, there may be an input insurance wire, the printed line on the printed line is burned, but the dangerous phenomenon of burning.
2, according to the capacity configuration load, there are many types of loads, in addition to the resistive load, there is also an inductive, capacitive and rectifier load, so the output current of the UPS includes a certain amount of reactive components in addition to the output current. The user should ensure that the power and capacity do not exceed the output indicators of uninterrupted power supply, and there is a certain margin to prevent AC motor load. 3, UPS is not suitable for booting and shutdown without delaying the high-power reserve UPS power supply, the boot boot is easy to start in the start-up, burn the end-class drive element of the inverter, because the control circuit is controlled The work has not yet entered a steady state, and the moment of starting will have a large surge current, and the final drive element may not bear.
When the load is included in the load, the load shutdown is also possible to cause damage to the end-level drive element. 4. When the UPS power supply in the correct order is in use, it should prevent the prisoner load and sudden reduction, and its voltage output fluctuates often, leading to the normal operation.
Therefore, to operate according to the correct switching sequence. 5, work environment high-power UPS power environment has - some standards, important temperature, humidity, dustproof. The device should be placed in a dry, ventilated, clean environment, preventing direct sunlight from being in the equipment, and the ambient temperature is preferably maintained between 18c to 25c.
Second, online uninterrupted power supply system usage skills 1, most small online UPS power supply. 2. The switch of the exchange cabinet using the online UPS power supply can be connected with a swivel switch or a fuse fuse.
Need to use air switch, it has the function of arc. When the load or online UPS power is short-circuited, the response speed is fast, and the function of leakage protection and overheating protection. 3, according to the relevant provisions of the UPS manufacturer's product manual to ensure the phase line, neutral line, and ground wire connected to the online UPS power supply can meet the requirements, and cannot change the order between each other.
4, most online UPS power supplies have the function of anti-interference and automatic regulator, the maintenance of the city electricity voltage needs to meet the requirements of the online UPS power supply for input voltage as much as possible. 5, moderate discharge is conducive to activating the battery, if it does not stop the market for a long time, it is also necessary to discharge it every 3 months. Use the UPS power supply with load to discharge once, extend the battery life.
Third, the online interactive uninterrupted power supply system is used, the voltage polarity is correct when the battery is connected; UPS first on the market, then pick up the battery. 3. When the voltage of the mains power supply is between 175 to 264V, at the purpose of the logic control circuit of the UPS power supply, the switch K0 is closed, and the small relay used as the translation switch used as the conversion switch is normally closed.
The contact is turned on, so that the unstable market power supply is delivered directly to the load. 4, the main state of the main network: The grid input current enters the two-way converter for rectification, and the rectified current is charged all the way to the UPS battery pack, and the other path is converted to an alternating power supply to the load. 5, the city's abnormal state: the power grid input current is abnormal or interrupted, the UPS power will immediately interrupt the market power supply.
Since the online interactive UPS power inverter has been working in a working state, its conversion time is 0ms, and the device does not have any impact. The use of uninterruptible power systems is first, and when performing, it should be clearly related issues. How to extend the power supply time of uninterrupted power supply, there are currently two ways, which are external large-capacity battery packs, buy larger power systems.
Of course, different solutions, the specific operation skills are different. When the method of external large-capacity battery pack is selected, it is clear that the specific power supply time is specifically, the load power is specifically, and then select the corresponding external battery pack. When this method is adopted, the battery pack is relatively added.
And use a larger power system, which can reduce maintenance costs relatively. Even if the load device is to be expanded, the large-capacity uninterrupted system can also function properly. Second, in the boot operation, it should be in order to select the battery switch, the automatic bypass switch, and the output switch is placed in the open file.
When the button is turned on, the power system will start slowly, and at this time, there should be carefully observation of the change in indicator light about the majority of users. Third, during the daily switching process, as long as the opening button is pressed, it can open other instruments to use it about twenty minutes. When the power is started to enter the stable working state, the load device power switch can be turned on.
At this time, it should also be clear that the power supply should be closed when the switch is maintained in normal operation. If you need to get the relevant functions of the UPS power supply, you must extend the power supply time and service life of the UPS uninterrupted power supply, understand the specific use skills, which is especially important.
