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.
Guo Xinjun, Captain Captain Captain, Shati Buck District, said. The garbage transfer station in Chalbag Street is one of the 13 garbage transshipment stations in the sand area, undertakes the riding mountain area, Xishan District, Pingdingshan District, Sanitation Road District, The transfer quantity of the six regions of the red temple district and Bayi street. The transfer station of 600 square meters is around 180 tons daily. Guo Xinjun said that in order to transfer garbage in time, the government has also purchased the vehicle, and now the transport vehicle is reached. 19. The next step will establish a long-term mechanism, and the timing is fixed, and the responsibility is implemented. For the odorous trench, the people reflected in the masses, Zhang Jian, Jiujiawan Reservoir Management Station Station, Shayibak District, Immediately Rectification, use three days, overnight overtime laying lines into the urban drainage network.
