说明绝缘老化特性下的三个元件,热点极限、老化因子极限和寿命损失极限,必须使用编程到继电器中的一组有效变压器数据进行测试。环境温度也必须编程(从电阻式温度检测器获得或编程为12个月的平均值)。试验包括通过向绕组1相a施加正确频率的电流信号来模拟变压器负载。7.5.19.2热点极限热点温度值是负载、环境温度和变压器额定值的函数。 向绕组1相a施加电流,以表示变压器上至少有100%的负载。 使用A2计量 生命损失 HOTTEST-SPOT WINDING TEMPERATION(热点绕组温度)实际值用于观察热点的温度逐渐升高。为了更快的温度上升,可以增加模拟负载。当热点温度达到S4元件时 绝缘老化 热点极限 HOTTEST-SPOT LIMIT PICKUP操作水平,元件应运行。 根据FlexLogic验证所有编程的继电器操作™ 设置。 验证所有目标和信息是否符合预期和编程设定。可以用手表验证时间延迟,因为延迟通常设置为分钟
Description The three elements under the insulation aging feature, hottest-spot limit, aging factor limit, and loss of life limit, must be tested with a valid set of transformer data programmed into the relay. The ambient temperature must also be programmed (obtained from an RTD or programmed as 12-month averages). The tests consist of simulating transformer loading by applying a current signal to winding 1 phase A at the correct frequency. 7.5.19.2 Hottest-spot Limit The hottest-spot temperature value is a function of load, ambient temperature, and transformer rating. Apply a current to winding 1 phase A to represent at least a 100% load on the transformer. Use the A2 METERING LOSS OF LIFE HOTTEST-SPOT WINDING TEMPERATURE actual value to observe the hottest spot temperature increases gradually. The simulated load to may be increased for a faster temperature rise. When the hottest spot temperature reaches the S4 ELEMENTS INSULATION AGING HOTTEST-SPOT LIMIT HOTTEST-SPOT LIMIT PICKUP operating level, the element should operate. Verify all programmed relay operations as per FlexLogic™ settings. Verify that all the targets and messages are as expected and programmed. The time delay can be verified with a watch as the delay is normally set in minutes
