电泳电源简介中英对照版

Power Supplies-电源：Rectifiers should be capable of voltage adjustment between 0-500 volts. Operating history has shown a power consumption of approximately 2.5 amp hours/100 ft for current electrocoat products. System design should include an allowance for an additional 50% amperage to provide for future developments. Average current requirements for coating a vehicle can be calculated by using this equation: 整流器电压能使电压在0-500V之间可调，实践经验表明厚膜电泳漆电流消耗大约为2.5安培 .小时/100平方英尺，系统设计要考虑50%的电流余量以供将来发展，可用以下公式计算泳涂一台车所需总电流。 Amps Required =(2.5 Amp Hrs/100 Ft ) x (Coatable Surface/Minute) x (60 Minutes/Hr) 所需安培数=（2.5安培.小时/100平方英尺）x（能涂的面积/分） x（60分/小时） Multiply the amps required by 1.5 to determine amplifier size to include the safety factor. The total amperage is divided into two zones; several rectifier modules are used in each zone (see Figure 12). Back-up rectifiers should be included in the design with proper switching to assure that production will be uninterrupted and quality undiminished in the event of rectifier failure. Current-limiting rectifiers are recommended for equipment protection. Variable-time, ramped-voltage circuitry is recommended for starting systems occurring after conveyor stops to prevent current surges which can damage coatings. Ramps of 10-15 seconds from 0 voltage to operating voltage have performed well. The rectifiers should be installed so that no power to the system is present when no production is in the tank (during lunch breaks, e.g.). 考虑安全系数，这个安培数乘以1.5来求出放大的规格，把总流量分成两份，每一部分单独配整流器（见图12），设计要考虑配有专用及独立启动的备用整流器，以确保即使整流器发生故障时生产也能继续进行且质量不降低。建议采用限流整流器以保护设备。考虑停链之后工艺槽中有工件在重新启动，要求有可调时间的渐升电压电路，这样的电路可防止电流脉冲损坏涂层继电器设备，从零伏升到工作电压的升压时间以10-15秒较好，要装有能控制不生产时（如午餐等）不为系统供电的控制器。 The degree of "smoothness of power" or ripple delivered by a rectifier is important. The D.C. power should be filtered such that the magnitude of peak voltages does not exceed 5% of the average D.C. with a voltage ripple of less than 5% under all load conditions. 整流器“供电平稳”度或输出脉动率很重要，直流电要经滤波，电压脉冲幅度不超过平均直流电压的5%，满负荷情况下，电压脉动率要小于5%。 Ripple is defined as: 脉动率定义为： 100 x RMS Voltage of the A.C. Wave on the D.C. / the Average D.C. 100 x在直流电压上的有效交流电压/平均直流电压 Grounded power-on entry provides the greatest personal safety, the least complicated switching system, and the longest coating times on lower body areas. It also reduces arcing and pitting of shoes and contact skids. 工件带接地电压入槽提供了最大的人身安全性，使开关系统更简化，且能得到对车身下部最长的电泳时间，同时也能减少电弧放电和烧坏电制，滑架等事故。
