AMAT 0020-24007自动化控制模块

产品详细资料
降低直流部件，直到元件复位。重置值应比操作值大大约2%。 如果目标功能设置为“自复位”，则验证拾取和报警指示灯是否复位。跳闸LED应保持锁定状态。7.6.2.2操作时间为了测量该元件的基本操作时间， 预设一个基波和直流分量复合电流信号，使元件工作。 使用第7–4页图7–1的设置：测试设置，在触发计时器的同时，突然施加电流。测量的操作时间应与元件的时间延迟设置相对应。7.6.3变压器过载变压器过载元件使用每个绕组的A相电流来计算变压器负载。计算假设wInding上有额定电压，因此负载实际上是额定负载电流的百分比。7.6.3.1操作水平 向绕组1的a相注入基频电流。 将电流信号增加到刚好高于变压器过载拾取设置的值（考虑CT比和额定MVA相电流以正确设置电流）。该元件应在其设置的时间延迟之后运行。 检查跳闸、拾取（和报警，如果选择）指示灯是否亮起，并显示以下其中一项：锁定：前过载或操作：前过载 降低电流，直到元件复位。复位值应约为操作值的97%。 如果目标功能设置为“自复位”，则验证拾取和报警指示灯是否复位。跳闸LED应保持锁定状态。
Lower the DC component until the element resets. The reset value should be approximately 2% larger than the operate value.  Verify that the Pickup and Alarm LEDs reset if the target function is set to Self-resetting. The Trip LED should remain latched. 7.6.2.2 Operating Time To measure the basic operating time of this element,  Preset a fundamental and DC component composite current signal to cause the element to operate.  Using the setup of FIGURE 7–1: Test setup on page 7–4, apply the current suddenly, at the same time the timer is triggered. The measured operating time should correspond to the time delay setting for the element. 7.6.3 Transformer Overload The transformer overload element uses the phase A current of each winding to compute a transformer loading. The computation assumes a rated voltage on the wInding, hence the loading is effectively a percent of rated load current. 7.6.3.1 Operating Level  Inject a fundamental-frequency current into phase a of winding 1.  Increase the current signal to a value just above the transformer overload pickup setting (take into account the CT ratio and the ratedMVA phase current to set the current correctly). The element should operate after its set time delay.  Check that the Trip, Pickup (and Alarm if selected) LEDs are on, and one of the following is displayed: LATCHED: Xformer Overload or OPERATED: Xformer Overload  Lower the current until the element resets. The reset value should be approximately 97% of the operate value.  Verify that the Pickup and Alarm LEDs reset if the target function is set to Self-resetting. The Trip LED should remain latched.
