EPS topology design is not a simple combinationSome 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.
After approval by the provincial party committee, the provincial government, the second batch of environmental protection inspections in our province has been officially launched. On August 28, the reporter learned from the Leading Group of the Shaanxi Provincial Environmental Protection Inspector Inspector, the first, second and third environmental protection inspectors of the Provincial Party Committee entered Xianyang, Baoji, and Hanzhong, three cities. Environmental protection inspector work. The environmental inspector is subject to the supervised party committees, governments and relevant departments, and sinking to some districts. Specifically inspected the city's 18th National Congress, the city has implemented state environmental protection decision-making deployment, highlighting environmental issues and treatment, and the relevant departments of environmental protection perform their duties and key tasks of environmental protection.

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.
