RadiSys PRE-913423数字量输入卡件

产品详细资料
本节包含配置过励磁监测元件的设置。包括一个五次谐波电平和两个伏特/赫兹元件，每个元件都有一个拾波电平和一个延时小工作电流：输入允许五次谐波水平元件工作所需的小电流值（以继电器标称电流为单位）。•第五谐波电平拾取：输入第五谐波电流（单位：%ƒ0），超过该电流，第五谐波水平元件将拾取并启动延迟定时器。•第五谐波电平延迟：输入在元件工作之前，第五谐波电流必须保持在拾波电平以上的时间。伏特/赫兹元件使用电压端子的实际测量电压与测量系统频率的比值。例如，在60Hz下测得的120伏的相电压与相电压的比值为2V/Hz。对于115%的过载，每赫兹小拾取电压的设置为2.3 V/Hz。该元件具有线性复位特性。重置时间可以编程为与受保护设备的冷却特性相匹配。电压-珀-赫兹复位值后，元件将完全复位。伏特/赫兹函数可以用作没有故意延迟的瞬时元件，用作确定的时间元件，或用作逆定时元件。
This section contains the settings to configure the overexcitation monitoring elements. Included are a 5th harmonic level, and two volts-per-hertz elements, each with a pickup level and a time delay MINIMUM OPERATING CURRENT: Enter the minimum value of current (in units of relay nominal current) required to allow the 5th harmonic level element to operate. • 5TH HARMONIC LEVEL PICKUP: Enter the 5th harmonic current (in %ƒ0) above which the 5th harmonic level element will pickup and start the delay timer. • 5TH HARMONIC LEVEL DELAY: Enter the time that the 5th harmonic current must remain above the pickup level before the element operates.The volts per hertz element uses the ratio of the actual measured voltage at the voltage terminal and the measured system frequency. For example, a measured phases-to-phase voltage of 120 volts at 60 Hz, results in a ratio of 2 V/Hz. For 115% overload, the setting of the volts per hertz minimum pickup would be 2.3 V/Hz. The element has a linear reset characteristic. The reset time can be programmed to match the cooling characteristic of the protected equipment. The element will fully reset after the VOLTS-PER-HERTZ RESET value. The volts per hertz function can be used as an instantaneous element with no intentional delay, as a definite time element, or as an inverse timed element.
