RADISYS 90009100输入输出模块

产品详细资料
中性点瞬时过电流2中性点瞬时过电流2元件与中性点瞬间过电流1元件相同。因此，可以使用相同的测试程序来验证它们的正确操作。禁用除中性瞬时过电流2以外的所有保护功能，并按照上一节中的步骤，对由中性瞬时过流2元件操作的LED和输出继电器进行适当的更改。7.5.10接地时间过电流7.5.10.1说明本程序验证接地时间的过电流性能是否与运行设置相匹配。由于这些元件可以分配大量的时序曲线，因此应在测试前准备一份预期操作时间与施加电流的关系表。接地元件测量连接到接地电流输入CT、H10和G10或F12和E12的电流信号。有关时序曲线的信息，请参阅第5-58页的时间过电流曲线。只能有一个或两个接地时间过电流元件同时使用。如果在测量操作时间时将继电器元件设置为“线性”复位特性，则确保在测试电流注入之间有足够的时间使元件完全复位。否则，将获得错误的定时测量值。这些元素的设置将在S4元素下找到 地面有机碳 W1 GND TIME OC设定点菜单。7.5.10.2绕组1元件为确保只有接地时间过电流元件操作逻辑选择的跳闸继电器（以及任何其他输出继电器）， 禁用除接地时间过电流以外的所有保护功能。使用图7-9所示的一般测试设置
Neutral Instantaneous Overcurrent 2 The neutral instantaneous overcurrent 2 elements are identical to the neutral instantaneous overcurrent 1 elements. Consequently, the same test procedure can be used to verify their correct operation. Disable all protection features except neutral instantaneous overcurrent 2 and follow the steps in the previous section, making the appropriate changes for the LEDs and output relays operated by the neutral instantaneous overcurrent 2 elements. 7.5.10 Ground Time Overcurrent 7.5.10.1 Description This procedure verifies that the ground time overcurrent performance matches the inservice settings. Since these elements can be assigned a multitude of timing curves, a table of expected operating times versus applied current should be prepared prior to testing. The ground element measures the current signal connected to the ground current input CT, H10 and G10 or F12 and E12. Refer to Time Overcurrent Curves on page 5–58 for information on timing curves. There can only be one or two ground time overcurrent elements in service at the same time. If the relay elements are set for the “Linear” reset characteristic when measuring the operating times, ensure there is sufficient time between test current injections for the element to reset fully. Otherwise, erroneous timing measurements will be obtained. The settings for these elements will be found under the S4 ELEMENTS  GROUND OC  W1 GND TIME OC setpoints menu. 7.5.10.2 Winding 1 Element To ensure that only the ground time overcurrent element operates the trip relays (and any other output relays) selected by the logic,  Disable all protection features except ground time overcurrent. Use the general test setup shown in FIGURE 7–9
