产品详细资料
•模拟输入范围:选择连接到模拟输入的转换器的电流输出范围。单位由模拟输入单位设置点定义。•模拟输入小值/大值:输入测得的量值,该值对应于传感器的小/大输出值。单位由模拟输入单位设置点定义。本节分配了用于监测每个绕组所有三相电流需求的需求设置点。745的电流需求是通过三种方式之一执行的:热需求、滚动需求或闭塞间隔。•电流需求表类型:选择用于电流需求测量的方法。选择“Thermal”模拟峰值记录热需求表的动作。745每秒测量一次每相上的电流,并假设电路量保持在这个值,直到下一次测量更新为止。它计算“热需求当量”如下:(EQ 5.3),其中d=施加输入后的需求时间t(以分钟为单位)d=输入量(常数)选择“块间隔”以计算编程需求时间间隔内的电流线性平均值,从每天00:00:00(即上午12点)开始。每天1440分钟被划分为由编程时间间隔设置的块的数量。每个新的需求值在每个时间间隔结束时都可用。
• ANALOG INPUT RANGE: Select the current output range of the transducer that is connected to the analog input. The units are defined by the ANALOG INPUT UNITS setpoint. • ANALOG INPUT MINIMUM/MAXIMUM: Enter the value of the quantity measured which corresponds to the minimum/maximum output value of the transducer. The units are defined by the ANALOG INPUT UNITS setpoint.This section assigns the demand setpoints for monitoring current demand on all three phases of each windings. Current demand on the 745 is performed one of three ways: thermal, rolling demand, or block interval. • CURRENT DEMAND METER TYPE: Select the method to be used for the current demand metering.Select “Thermal” to emulate the action of an analog peak-recording thermal demand meter. The 745 measures the current on each phase every second, and assumes the circuit quantity remains at this value until updated by the next measurement. It calculates the ‘thermal demand equivalent’ as follows: (EQ 5.3) where d = demand after applying input for time t (in minutes) D = input quantity (constant) Select “Block Interval” to calculate a linear average of the current over the programmed demand TIME INTERVAL, starting daily at 00:00:00 (that is, 12 am). The 1440 minutes per day is divided into the number of blocks as set by the programmed time interval. Each new value of demand becomes available at the end of each time interval.
