RadiSys 97-9525-23编码器

产品详细资料
对于定时测试，信号发生器必须能够在几毫秒内触发频率的逐步变化或斜坡下降到预先选择的频率。 连接信号源和定时器启动触发器，如图7-12所示：第7-44页的频率元件测试。 将电流设置为额定CT二次值，无电压连接，并将预触发频率设置为标称频率（60或50 Hz）。 将后置触发器设置为低于低频率1设置0.5 Hz。如有必要，重置所有目标和继电器。 重置计时器。 启动频率步进和定时器启动。间隔计时器将记录元件的工作时间。 将此时间与S4元素进行比较 频率 低频率1 欠频率1延迟设置 如果操作时间不分散在大范围内，则可能需要重复该测试几次并对结果进行平均。 如果存在大范围散射，请验证测试设置，并确保信号源以一致的方式工作。注意：如果启用了来自逻辑输入的阻塞，则可以按照前面对其他元素的测试所述进行测试。7.5.17.3低频2 禁用除低频率2功能外的所有保护功能。 验证设置是否符合使用中的要求。在S4元素中输入/修改设置和逻辑 频率 UNDERFREQUENCY 2设定点菜单。 对该元素重复第7–44页低频1的相应步骤。 将结果与低频率2元件的设置进行比较。
For timing tests, the signal generator must be capable of triggering into step-wise changing of frequency or ramping down to a pre-selected frequency in only a few milliseconds.  Connect the signal source and timer start triggers as shown in FIGURE 7–12: Frequency element testing on page 7–44.  Set the current to rated CT secondary value, no voltage connection, and the pre-trigger frequency to the nominal frequency (60 or 50 Hz).  Set the post-trigger to 0.5 Hz below the underfrequency 1 setting. If necessary, reset all targets and relays.  Reset the timer.  Initiate the frequency step and timer start. The Interval Timer will record the operating time of element.  Compare this time to the S4 ELEMENTS  FREQUENCY  UNDERFREQUENCY 1  UNDERFREQUENCY 1 DELAY setting  Provided that the operate times are not scattered over a wide range, it may be desirable to repeat this test several times and average the results.  If there is a wide scatter, verify the test setup and ensure the signal source behaves in a consistent manner. Note The blocking from logic input, if enabled, can be tested as described in earlier tests for other elements. 7.5.17.3 Underfrequency 2  Disable all protection functions except the underfrequency 2 function.  Verify that settings match in-service requirements. Enter/modify settings and logic in the S4 ELEMENTS  FREQUENCY  UNDERFREQUENCY 2 setpoints menu.  Repeat the appropriate steps of Underfrequency 1 on page 7–44 for this element.  Compare the results to the settings for the underfrequency 2 element.
