EPS topology design is not a simple combination
Some people think: EPS (electronic part) = rectified / charger + inverter + output conversion switch (kit) + control unit and other components can constitute a emergency power supply. Nice, the basic unit of the EPS is composed of the above part, but in order to meet the whole machine reliability (MTBF), how the reliability of each basic unit is * reasonable? The following formula tells us: EPSMTBF = (Rectifier / Charger) MTBF + (inverter) MTBF + (Conversion Switch) MTBF + (Control Unit) MTBF
As can be seen from the above formula, the MTBF of the EPS machine is superimposed by MTBF of most parts, so the overall design of the EPS requires detailed research, analysis, calculating MTBF of most parts, improves the MTBF of weak components, and the overall safety life from EPS The needs of the cycle are configured to configure the safety life cycle of the major components.
Case 6: Liuhe County Liangshui Town destroyed forest land reclamation, destroying the ecological environment on August 23, 2017 The forest land is destroyed, especially in Liangdong Village, Liangxi Village, Yao Dawang Village, Waist Station Village, Xuchang Village, Tahe Village Destroyed Forest Wilderness Corn Phenomenon; the town Linfang forest staff was managing the above problems, Cadre obstructive. After investigation, the people reflect the part. According to the research decisions of the discipline committee of Liangshui Town, Liuhe County, Wang Kuiren, for the former deputy secretary of the Party branch of Xitu Village, gave a notification of the party’s internal positions and announced the newspaper of the Party Branch of Xitu Village.
Introduction to the emergency power supply valve controlled lead-acid battery life
Depth discharge, periodically depth discharge is the main measures for the necessary maintenance of the battery, although the lead-acid battery does not have memory, the battery is maintenance, but it is not to maintain, this is a misunderstanding, depth discharge can increase the activity of the battery. It is a great role in improving the capacity of the battery.
The reason for physical damage, physical damage is generally not known by consumers, and its severity is very terrible. Physical damage is necrosis of polar corrosion, falling off, and breakage caused battery cells, not repaired. This situation is generally liquid There are many types of battery, due to the precursor of charging, the concentration of liquid is increased, and the plates of the top end of the plate do not have a liquid circulation, and the phenomenon of corrosion falling off. If it is not added, it will break, so There are many phenomena, and the dryness will happen.
