Radisys P945GM自动化工控设备

产品详细资料
•小工作电流：输入允许THD电平元件工作所需的小电流值（以继电器标称电流为单位）。•W1（3）THD拾取电平：输入总谐波失真（单位：%ƒ0），超过该值，绕组1（3）总谐波失真元件电平将拾取并启动延迟定时器。•W1（3）THD LEVEL DELAY（THD电平延迟）：输入总谐波失真在元件工作之前必须保持在拾取电平以上的时间。•小工作电流：输入允许谐波降额元件运行所需的小电流值（以继电器标称电流为单位）。•W1（3）谐波降额拾取：输入谐波降额，低于该值，绕组1（3）的谐波降额将拾取并启动延迟定时器。•W1（3）谐波降额延迟：输入谐波降额必须在元件运行前保持在拾取水平以下的时间。745绝缘老化/寿命损失特征基于IEEE标准C57.91–1995、IEEE矿物油浸入式变压器加载指南和C57.96–1989中提出的计算方法，IEEE干式配电变压器和电力变压器负载指南。这些标准提供了一种计算顶部油温、变压器内部热点、老化系数和总累积寿命损失的方法。
• MINIMUM OPERATING CURRENT: Enter the minimum value of current (in units of relay nominal current) required to allow the THD level element to operate. • W1(3) THD PICKUP LEVEL: Enter the total harmonic distortion (in %ƒ0) above which the winding 1(3) total harmonic distortion element level will pickup and start the delay timer. • W1(3) THD LEVEL DELAY: Enter the time that the total harmonic distortion must remain above the pickup level before the element operates.• MINIMUM OPERATING CURRENT: Enter the minimum value of current (in units of relay nominal current) required to allow the harmonic derating element to operate. • W1(3) HARMONIC DERATING PICKUP: Enter the harmonic derating below which the winding 1(3) harmonic derating will pickup and start the delay timer. • W1(3) HARMONIC DERATING DELAY: Enter the time that the harmonic derating must remain below the pickup level before the element operates.The 745 insulation aging / loss of life feature is based on the computational methods presented in IEEE standards C57.91–1995, IEEE Guide for Loading Mineral-Oil-Immersed Transformers, and C57.96–1989, IEEE Guide for Loading Dry-Type Distribution and Power Transformers. These standards present a method of computing the top oil temperature, the hottest spot inside the transformer, the aging factor, and the total accumulated loss of life.
