产品详情

产品详细资料
•W1(3)相位时间OC复位:选择“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,例如大多数具有瞬时复位特性的静态装置。•W1(3)谐波降额校正:选择“启用”可启用绕组1(3)相时间过电流曲线的谐波自动降额校正。745计算提供非正弦负载电流时的变压器减额能力(根据ANSI/IEEE C57.110-1986),并且当启用该功能时,自动切换相位-时间过电流曲线拾取,以保持相对于变压器热损伤曲线所需的保护裕度,如下图所示。•W1(3)PHASE INST OC 1(2)PICKUP:输入相电流水平(以继电器标称电流为单位),超过该水平,绕组1(3)相瞬时过电流1元件将拾取并启动延迟定时器。•W1(3)相位INST OC 1(2)DELAY(延迟):输入元件工作前相电流必须保持在拾取电平以上的时间。注:对于相位瞬时过电流2元件,上面的设定点信息和下面的逻辑图是相同的。
• W1(3) PHASE 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. • W1(3) HARMONIC DERATING CORRECTION: Select “Enabled” to enable automatic harmonic derating correction of the winding 1(3) phase time overcurrent curve. The 745 calculates the derated transformer capability when supplying non-sinusoidal load currents (as per ANSI / IEEE C57.110-1986) and, when this feature is enabled, automatically shifts the phase time overcurrent curve pickup in order to maintain the required protection margin with respect to the transformer thermal damage curve, as illustrated below.• W1(3) PHASE INST OC 1(2) PICKUP: Enter the level of phase current (in units of relay nominal current) above which the winding 1(3) phase instantaneous overcurrent 1 element will pickup and start the delay timer. • W1(3) PHASE INST OC 1(2) DELAY: Enter the time that the phase current must remain above the pickup level before the element operates. Note The setpoint messages above and the following logic diagram are identical for the phase instantaneous overcurrent 2 element.
