产品详细资料
禁用除过频以外的所有保护功能。 验证设置是否符合使用中的要求。S4 ELEMENTS中修改了过频设置 频率 OVERFREQUENCY(频率过高)设置菜单。电压输入功能(启用电压输入):使用连接到端子C11和C12的变频电压/电流源作为电压信号,连接到端子H1和G1作为电流信号, 将频率设置为60.00 Hz(或50.00 Hz),将电压幅度设置为额定VT二次电压。 将电流幅度设置为额定CT次级。 监测适当的跳闸和辅助继电器。 重置继电器上的所有警报和指示。745显示屏应保持不变,没有跳闸指示。 缓慢增加频率,直到输出继电器工作。 检查进行操作的频率是否为选定的频率设置。 随着频率的变化,验证A2 METERING 频率 SYSTEM FREQUENCY(系统频率)实际值表示系统频率的正确值。 慢慢降低电压。 注意输出继电器复位时的电压。 检查该压降是否等于S4元件 频率 过频 低工作电压电压水平。请注意,该电平可以设置为0.00 A,在这种情况下,元件保持工作在大约标称2%的电压电平。 缓慢增加电压,并在电压达到设定水平以上2%时检查元件是否工作。 将电压恢复到标称值。 慢慢减小电流,直到元件复位。 检查该漏电流电平是否等于S4元件 频率 过频 小工作电流设置。
Disable all protection functions except overfrequency. Verify that settings match in-service requirements. Overfrequency settings are modified in the S4 ELEMENTS FREQUENCY OVERFREQUENCY settings menu. Voltage input function (voltage input enabled): Using the variable-frequency voltage/current source connected to terminals C11 and C12 for the voltage signal and H1 and G1 for the current signal, Set the frequency to 60.00 Hz (or 50.00 Hz) and the voltage amplitude to the rated VT secondary voltage. Set the current amplitude to rated CT secondary. Monitor the appropriate trip and auxiliary relays. Reset all alarms and indications on the relay. The 745 display should remain unchanged with no trip indications. Slowly increase the frequency until the output relay(s) operate. Check that the frequency at which operation took place is the selected frequency setting. As the frequency is varied, verify that the A2 METERING FREQUENCY SYSTEM FREQUENCY actual value indicates the correct value of system frequency. Slowly reduce the voltage. Note the voltage at which the output relay(s) reset. Check that this dropout voltage is equal to the S4 ELEMENTS FREQUENCY OVERFREQUENCY MINIMUM OPERATING VOLTAGE voltage level. Note that this level can be set down to 0.00 A, in which case the element remains operated to a voltage level of approximately 2% of nominal. Slowly increase the voltage and check that the element operates when the voltage reaches 2% above the set level. Return the voltage to nominal value. Slowly decrease the current until the element resets. Check that this dropout current level is equal to the S4 ELEMENTS FREQUENCY OVERFREQUENCY MINIMUM OPERATING CURRENT setting.
