产品详细资料
在745中,“中性”是指残余电流(3I0),内部计算为三相的矢量和。继电器包括中性时间过电流和每个绕组的两个中性瞬时过电流水平•W1(3)中性时间OC PICKUP:输入中性电流水平(以继电器标称电流为单位),超过该水平,绕组1(3)的中性时间过流元件将拾取并开始计时。•W1(3)空档时间OC形状:选择绕组1(3)中性时间过电流元件要使用的时间过电流曲线形状。第5-58页的时间过电流曲线描述了时间过电流的曲线形状。•W1(3)NEUTRAL TIME OC MULTIPLIER(空档时间OC乘数):输入乘数常数,所选时间过电流曲线形状(基准曲线)将通过该乘数常数在时间上偏移。•W1(3)NEUTRAL TIME OC RESET(空档时间OC复位):选择“Linear”(线性)复位以与机电时间过电流继电器协调,其中复位特性(当电流在跳闸前降至复位阈值以下时)与累积能量与跳闸所需能量之比成比例。选择“瞬时”复位与继电器协调,如大多数具有瞬时复位特性的静态装置。
In the 745, “neutral” refers to residual current (3I 0), calculated internally as the vector sum of the three phases. The relay includes neutral time overcurrent and two levels of neutral instantaneous overcurrent for each winding • W1(3) NEUTRAL TIME OC PICKUP: Enter the level of neutral current (in units of relay nominal current) above which the winding 1(3) neutral time overcurrent element will pickup and start timing. • W1(3) NEUTRAL TIME OC SHAPE: Select the time overcurrent curve shape to be used for the winding 1(3) neutral time overcurrent element. The Time Overcurrent Curves on page 5–58 describe the time overcurrent curve shapes. • W1(3) NEUTRAL TIME OC MULTIPLIER: Enter the multiplier constant by which the selected time overcurrent curve shape (the base curve) is to be shifted in time. • W1(3) NEUTRAL TIME OC RESET: Select “Linear” reset to coordinate with electromechanical time overcurrent relays, in which the reset characteristic (when the current falls below the reset threshold before tripping) is proportional to ratio of energy accumulated to that required to trip. Select “Instantaneous” reset to coordinate with relays, such as most static units, with instantaneous reset characteristics.
