Radisys 135837-008数字量输入卡件

产品详细资料
•OVERFREQUENCY DELAY（过频延迟）：输入元件工作前频率必须保持在拾取电平以上的时间。变压器设计为在变压器铁芯中的大磁通密度或以下工作。超过该设计限制，堆芯和附近导电部件中的涡流会导致过热，在很短的时间内可能会造成严重损坏。磁芯中的磁通量与施加到绕组的电压除以绕组的阻抗成比例。堆芯中的磁通量随着电压的增加或频率的降低而增加。在发电机连接的变压器启动或关闭期间，或甩负荷后，变压器可能会出现过大的伏赫兹比，即过励磁。当变压器铁芯过励磁时，铁芯在非线性磁区工作，并在励磁电流中产生谐波分量。5次谐波的大量电流是过励磁的特征。
• OVERFREQUENCY DELAY: Enter the time that the frequency must remain above the pickup level before the element operates.A transformer is designed to operate at or below a maximum magnetic flux density in the transformer core. Above this design limit the eddy currents in the core and nearby conductive components cause overheating which within a very short time may cause severe damage. The magnetic flux in the core is proportional to the voltage applied to the winding divided by the impedance of the winding. The flux in the core increases with either increasing voltage or decreasing frequency. During startup or shutdown of generatorconnected transformers, or following a load rejection, the transformer may experience an excessive ratio of volts to hertz, that is, become overexcited. When a transformer core is overexcited, the core is operating in a non-linear magnetic region, and creates harmonic components in the exciting current. A significant amount of current at the 5th harmonic is characteristic of overexcitation.
