产品详细资料
每赫兹电压设置可在S4元件中找到 过励磁 VOLTSPER-HERTZ 1设定点菜单。 施加从60赫兹开始的电压,并增加幅度,直到元件工作。 以5 Hz为步长降低频率,并重复测量。该元件应在等于该元件设置的电压/赫兹的一致值下工作。 检查跳闸和拾取指示灯是否亮起,并显示以下跳闸信息之一:第7章:调试保护方案745变压器保护系统-说明手册7–53锁定:伏特/赫兹1或操作:伏特/Hz 1 对于定时测试,根据元件的选定定时曲线,准备一份预期工作时间与施加V/Hz信号的关系表。 使用变频函数发生器模拟不同的V/Hz比,突然施加到继电器上并测量操作时间。五次谐波方案如果连接到继电器的任何电流信号的五次谐波含量超过阈值设置,则五次谐波计划在设置的时间内运行,前提是电平高于设置的阈值。 禁用除五次谐波功能外的所有保护功能。第五谐波方案设置在S4 ELEMENTS中 过励磁 第5谐波电平设定点菜单。
The Volts-per-hertz settings are found in the S4 ELEMENTS  OVEREXCITATION  VOLTSPER-HERTZ 1 setpoints menu.  Apply a voltage starting at 60 Hz and increase the magnitude until the element operates.  Reduce the frequency in steps of 5 Hz and repeat the measurement. The element should operate at a consistent value of volts/hertz equal to the setting of the element.  Check that the Trip and Pickup LEDs are on and one of the following trip messages is displayed: CHAPTER 7: COMMISSIONING PROTECTION SCHEMES 745 TRANSFORMER PROTECTION SYSTEM – INSTRUCTION MANUAL 7–53 LATCHED: Volts-Per-Hertz 1 or OPERATED: Volts-Per-Hertz 1  For timing tests, prepare a table of expected operating time versus applied V/Hz signal from the selected timing curve for the element.  Using the variable frequency function generator to simulate the different V/Hz ratios, apply suddenly to the relay and measure the operating time.Fifth Harmonic Scheme The 5th harmonic scheme operates if the 5th harmonic content of any current signal connected to the relay exceeds the threshold setting, for the set time, provided that the level is above the set threshold.  Disable all protection functions except the 5th harmonic function. The 5th harmonic scheme settings are in the S4 ELEMENTS  OVEREXCITATION  5th HARMONIC LEVEL setpoints menu.
