UPS 1000W household mostly short delay following backup type. The basic component of such a UPS battery charger , battery pack, inverter three parts , some UPS on this basis also added exchange regulator power supply filter and other components, to further improve the performance of the UPS and practical sex .
Standby UPS or UPS failure in most parts of the battery pack , the battery pack as the price to account for the whole of 4O% or more, the replacement cost a lot. But usually as long as proper maintenance , you can make doubled to extend the life of the battery pack , even if there is some small problem, just take timely measures can be remedied.
General UPS battery pack consists of two 12V batteries in series 24V rabbit maintenance reserve power , which directly affects the performance and status of the UPS inverter and inverter startup time , a lot of trouble is caused by the battery pack . Although it is maintenance-free batteries, but in different conditions of use of its life is not the same . Maintenance-free battery block performance as usual using rechargeable nickel-cadmium batteries, require frequent charge and discharge in order to maintain its vitality, home users rarely encounter halfway down the block need UPS power inverter with battery supply situation is often battery block long floating state , so over time the battery capacity will gradually decline , early retirement . So artificially raised against this power inverter discharge , usually a home computer consumes about 200W , so the inverter load power would choose 200W. According to the characteristics of UPS inverter , pure resistive load to use , professional use of the optional high-power load wirewound resistors . In amateur conditions can make the best choice of a 200W incandescent bulb ( you can also use several small power light bulbs used in parallel ) , the choice of the benefits of this load is purely resistive load close to the power consumption is similar with the actual computer on the line, through inverter discharge can test out your actual UPS inverter power supply time . Benefits of doing so , one can later UPS mains power interruption would be able to know how much time support , two can be compared with the next discharge time , in order to understand the performance of the battery .
It should be noted yes. Bulbs for loads greater impact because the boot , in order to protect the safety of the UPS , you must perform the following steps : ( a ) the UPS is turned into phase power ; ( 2 ) Open the UPS; (3) Open the load ( lamp ) ; ( 4 ) disconnect the UPS charge 6 to 8 hours. As most of the UPS battery set up in order to protect the battery voltage is lower , once the battery voltage Yue Luo excessive inverter stops automatically . During the operation , we should pay attention to the inverter time record for future reference , note that UPS enclosure temperature , if the temperature rise is too large to be in time to stop the inverter , the inverter until the temperature returned to normal after discharge , until UPS automatically stops inverter ( the battery has run out ) . Above method because smaller power inverters , UPS left margin of the great power of the UPS inverter tube is not damaged , the general discharge once a month to maintain the vitality of the UPS battery .
Discharge method using the above , it is also a little trick is to determine your UPS is a sine wave or square wave inverter inverter . The UPS sine wave inverter better, while the square wave inverter inverter unsuitable for long-term use of some devices harmful . Sine wave inverter of the UPS inverter power supply into the state, as the load lamp brightness and the use of electricity as it was when the UPS square wave inverter in the inverter state , do load electricity than light bulbs when brighter.
The following is a further safeguard the UPS method that applies to certain electronic and electrical knowledge and have hands-on experience of the maintenance staff . In the fully discharged, the UPS stand for 3O minutes ( Do not turn on power charging ) , open the UPS cabinet , two were tested with a multimeter voltage of the battery block ( in the measurement when the best Multimeters parallel across the 120 ~ 200 ohm resistor as the load ) , two battery voltage difference should not be greater than 0.5V. If the voltage difference is greater than this , then the two batteries consistency is poor, this may cause a battery pack capacity is insufficient to allow them an early discharge termination of long-term effect on the two batteries are damaged. If detected early, can be artificially lower voltage battery block for supplement charge, so two of the battery voltage is maintained at the same level , and then replace the UPS can be. If you found a battery failure or aging , timely treatment or replacement. General conditions using the above method to check the battery every six months . If the conventional inverter discharge , found inverter inverter time than the last time was significantly reduced, this check can be carried out immediately .
As a complete microcomputer system support systems , UPS power to protect your equipment from damage data and has a very important role. Therefore , the proper use and maintenance of UPS, it is very important. To ensure normal operation and prolong its service life , the use and maintenance should pay attention to the following aspects:
( A ) in the left margin to match the power . As of 1000W UPS, at 80% load rate that is 800W to load.
( 2 ) new share of UPS power supply , the use of the former must be balanced on the back-up battery charging , the battery will each in parallel, according to the battery 's nominal value, to determine the charging voltage and current, charge 12 hours to 34 hours, in order to extend battery life.
( 3 ) during the UPS connection, should be properly connected to the AC input polarity , otherwise the failure rate will be greatly increased .
(4) UPS is switched long should minimize startup and shutdown times.
( 5 ) should not be in the UPS output load with thyristor , thyristor bridge rectifier or a half-wave rectifier load .
(6) UPS by mode of operation can be divided into Standby UPS and online UPS two kinds . On -line UPS should be noted: its former level should not be added with a large impedance element exchange regulator , because it will cause backup UPS mains power supply and the inverter transition time between the apparent increase is likely causing computer errors at run-time generated self start, resulting in loss of data ; on -line UPS should be noted : it is not the end of the access or the battery pack in the battery internal resistance varies greatly switched the case , it should not take the load turned on or off with a load .
( 7 ) regularly check inside the UPS battery terminal voltage and internal resistance , the battery pack in order to determine whether there is sufficient available capacity to prepare for the actual power interruption purposes. May take the following measures: a long period of only charging the battery does not discharge the UPS , the battery in order to prevent damage due to storage of aging should be every 2 to 3 months artificially interrupted electricity supply , so that the UPS battery discharge time in order to achieve the purpose of activating the battery . UPS for a long period of low voltage mains power supply or frequent users, in order to prevent battery damage due to charge long enough , you should take advantage of the peak power to charge the battery , in order to ensure that the battery after every discharge sufficient charging time. Non- compelling , do not let the battery depth of discharge . Because the number of deep discharge battery allows only 200 to 250 times.
( 8 ) When the UPS battery capacity is available for use when the majority let go , and had met with electricity from the battery when the power supply is interrupted , the UPS should not continue to be run under heavy load conditions , otherwise easily lead to battery failure or internal inverter failure.
( 9 ) the user themselves outside with time-lapse battery pack outside with charger with constant current and Huan should use pressure control characteristics of the brand , should not use ordinary constant-voltage charger , or likely to cause reduced battery life of the , severe burning charger ; external battery pack to the UPS connection between short and thick as possible .
( 10 ) use the UPS power, no need for AC regulator. If we must add , should be added to the UPS before the class, ie first by mains AC voltage regulator , and then by UPS, then to the load.
( 11 ) for non- maintenance-free batteries, should be checked regularly , control the temperature , add distilled water .
(12) UPS power supply should be used to avoid the short interval between the two boot . Otherwise , easy to burn out the machine components , the general wait time should be 1 minute or more .
(13) UPS should not be powered by a diesel generator , because of its frequent mutation frequency instability , affecting the normal operation of the UPS .
( 14 ) such as a UPS connected to more than one load equipment , power should be spaced in order to avoid load simultaneously when starting large current damage the power supply components.
( 15 ) Many UPS is equipped with an alarm switch, mains main role is to alert the user when to stop , as well as excessive battery discharge alarm , so in the course must take the buzzer switch.
