Radisys 61-0475-10工控DCS系统自动化设备

产品详细资料
所有差动电流均采用第7-11页“变压器选型”中所示的相同原理进行计算。差分电流的推导受到相移补偿和零序去除的影响。7.5.3.4目标、输出触点和显示操作 验证所有目标和输出触点的正确操作，并在测试期间显示消息。7.5.3.5逻辑输入的闭锁每个元件都可编程为通过逻辑输入、虚拟输入、虚拟输出、输出继电器操作或自检继电器操作进行闭锁。此测试验证差动元件是否可以被逻辑输入1阻断。 通过设置S4 ELEMENTS（S4元件）选择逻辑输入1 有差别的 差分百分比 差速块百分比设定值至Logc Inpt 1。 施加电流以操作差分元件，然后断言逻辑输入1。 验证元素是否已重置，并且所有目标都可以重置。 在逻辑输入1被断言的情况下，移除电流并重新施加。 验证元件是否未运行。说明本程序验证相位时间过电流元件性能是否与在用设置相匹配。由于这些元件可以具有多个时序曲线中的任何一个，因此在测试元件之前，应该准备预期操作时间与施加电流的关系表。有关时序曲线的信息，请参阅第5-58页的时间过电流曲线。
All differential currents are calculated using the same principal shown in Transformer Type Selection on page 7–11. The differential current derivation is affected by phase shift compensation and zero sequence removal. 7.5.3.4 Target, Output Contact, and Display Operation  Verify the correct operation of all targets and output contacts and display messages during testing. 7.5.3.5 Blocking from Logic Inputs Each element is programmable to be blocked by a logic input, virtual input, virtual output, output relay operation, or self-test relay operation. This test verifies that the differential element can be blocked by logic input 1.  Select Logic Input 1 by setting the S4 ELEMENTS  DIFFERENTIAL  PERCENT DIFFERENTIAL  PERCENT DIFFERENTIAL BLOCK setpoint to Logc Inpt 1.  Apply current to operate the differential element then assert logic input 1.  Verify that the element has reset and that all targets can be reset.  With logic input 1 asserted, remove the current and reapply.  Verify that the element did not operate.Description This procedure verifies that the phase time overcurrent element performance matches the in-service settings. Since these elements can have any one of a multitude of timing curves, a table of expected operating times versus applied current should be prepared prior to testing the elements. Refer to Time Overcurrent Curves on page 5–58 for information on timing curves.
