产品详细资料
绕组1限制性接地故障设置点如下所述：•W1（3）RESTD GND fault PICKUP：输入绕组1（3）限制性接地点故障元件的小接地差动电流水平（以与绕组相关的CT初级相为单位，其中设置了限制性接地线故障）。•W1（3）重启接地故障斜率：输入斜率百分比（接地差动电流与大线路电流的斜率）。•W1（3）RESTD GND FAULT DELAY（重启接地故障延迟）：输入绕组1（3）受限接地故障元件在元件运行之前必须保持拾取的时间。本节包含配置负序过电流元件的设置。包括每个绕组的负序时间过电流，以及每个绕组的负序瞬时过电流。•W1（3）NEG SEQ TIME OC PICKUP：输入负序电流水平（以继电器标称电流为单位），超过该水平，绕组1（3）负序时间过电流元件将拾取并开始计时。•W1（3）NEG SEQ TIME OC SHAPE：选择要用于绕组1（3）负序时间过电流元件的时间过电流曲线形状。有关时间过电流曲线形状的描述，请参阅第5-58页的时间过电流图。•W1（3）NEG SEQ TIME OC MULTIPLIER：输入所选时间过电流曲线形状（基准曲线）在时间上偏移的乘数常数。•W1（3）NEG SEQ TIME OC RESET：选择“线性”复位以与机电时间过电流继电器相协调，其中复位特性（当电流在跳闸前降至复位阈值以下时）与累积的“能量”与跳闸所需能量的比率成比例。选择“瞬时”复位与具有瞬时复位特性的继电器（如大多数静态装置）相协调。
The winding 1 restricted ground fault setpoints are described below: • W1(3) RESTD GND FAULT PICKUP: Enter the minimum level of ground differential current (in units of phase CT primary associated with the winding, where the restricted ground fault is set) for the winding 1(3) restricted ground fault element. • W1(3) RESTD GND FAULT SLOPE: Enter a slope percentage (of ground differential current to maximum line current). • W1(3) RESTD GND FAULT DELAY: Enter the time that the winding 1(3) restricted ground fault element must remain picked up before the element operates.This section contains the settings to configure the negative sequence overcurrent elements. Included are negative sequence time overcurrents for each winding, and negative sequence instantaneous overcurrents for each winding.• W1 (3) NEG SEQ TIME OC PICKUP: Enter the level of negative sequence current (in units of relay nominal current) above which the winding 1(3) negative sequence time overcurrent element will pickup and start timing. • W1 (3) NEG SEQ TIME OC SHAPE: Select the time overcurrent curve shape to be used for the winding 1(3) negative sequence time overcurrent element. Refer to Time Overcurrent Curves on page 5–58 for a description of the time overcurrent curve shapes.• W1 (3) NEG SEQ 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) NEG SEQ TIME OC RESET: Select the “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 the “Instantaneous” reset to coordinate with relays, such as most static units, with instantaneous reset characteristics.
