UPS repair bypass mode, UPS power supply ECO economy mode. When our UPS power is faulty, our equipment can't stop power, and then use maintenance bypass. ECO energy-saving operation mode, there is a detection board in the UPS power supply, if the city's electricity is relatively high, the city is refined bypass, reducing the power loss of the city, the use of power supply is not high, but there is energy-saving demand.
occasion. What is the UPS repair bypass mode? When the UPS device is going to perform routine maintenance or the DC screen of the power plant to be replaced, the user can stop the inverter first, and then close the maintenance bypass air switch, then disconnect the rectifier and spare bypass. air switch.
Thus, the AC power supplied to the load does not interrupts during the switching process, but in addition to the output terminal transformer, the UPS does not communicate or DC power, so it can effectively ensure the safety of the maintenance personnel. The maintenance bypass is to use the UPS to be used to power up the UPS! At this time, the load is powered by the maintenance bypass, the same is no purified market. Under normal circumstances, switching ups to maintenance bypass, first switch to static bypass.
How does UPS switch repair bypass? First turn off the UPS inverter, the UPS combines bypass switch, and then divides other switches, and the internal discharge of the UPS is complete, the multimeter measures no voltage to carry out maintenance work. The maintenance bypass switching of each manufacturer UPS power supply is not the same. It is recommended to contact the manufacturer consultation service, or view the UPS power usage and repair manual.
Switch UPS to repair bypass, first switch to static bypass. Switching UPS to repair bypass First switching to static bypass to ensure constant electricity, because this is to make two electric overlap to ensure constant electricity, if directly cut to repair bypass is two different points overlap will result in short circuits Burning the UPS, and the two electricity overlapping the first-cutly static bypass is the same. UPS Power ECO Economy Operation mode In addition to improving the efficiency of the UPS power supply, the UPS can also be utilized.
For example, the principle is like ECO's economy, which is to activate this function in a preferred market environment, so that the UPS is powered directly by static bypass. At this time, the inverter is in standby, but does not output energy, _ once The main electricity, the UPS power source is immediately switched to the inverter power supply, and the switching time is generally within 1 millisecond. Since the inverter is in standby, it is small, and the UPS can reach ~ 1j97%.
, Reduce loss of 3% higher than normal mode. The UPS power supply uses ECO mode to have 2 conditions: First, the static bypass must use two sets of high-reliable thyristors, and must not use the contactor to add a combination of gate, because the contact point will fire when the contactor can be fired, and hundreds of times work There is no normal work, and the thyristor does not exist, while the switching time can be shortened. Second, it is recommended to use in a good power environment, such as first-level power supply units, etc.
ECO mode of operation refers to the UPS power supply economy module. It is important for energy-saving and power-saving and power saving, high-power UPS electricity through inverter AC / DC, DC / AC, consumes a lot of power supply, if the power supply is calculated, the general UPS power efficiency It is 90%, then 10% consumption, this is 30 degrees of electricity, one year down UPS power consumption = 30 * 24 * 365 = 262800kw, if the electricity is one yuan, the electricity fee is required for one year 262800 yuan, it is especially important for energy conservation. In ECO mode, when the bypass is normal, the UPS power system is powered by bypass to load, inverter standby; when the bypass voltage / frequency exceeds a certain range, the UPS output is switched to inverter, and the operating efficiency can be as high as 98%.
80% of electricity can save 80% compared to a general UPS operating mode. ECO Working Principle: When the market is excellent, the UPS host system is powered by the bypass EMC filter output to the load, the inverter standby; when the market voltage or frequency is exceeded, the UPS is converted to a dual transform mode. Summary: ECO mode is one of the most advantageous technologies in UPS, important for energy-saving and environmental protection.
ECO energy-saving mode, allows the UPS power host to achieve 98%, saving 8% loss than the general working mode. .
