捡拾器液位 在禁用间隔计时器的情况下,施加电流信号并增加其幅值,直到跳闸继电器(以及所有选定的辅助继电器)工作。 将测量的操作水平与S4元件进行比较 相位OC W1相位INST OC 1 W1 PHASE INST OC 1 PICKUP设定值。 检查元件运行时跳闸、拾取和相位A(C)指示灯是否点亮。 检查是否显示以下消息之一:LATCHED a:W1 Phase Inst OC 1或OPERATED a:W1相位仪表OC 1减小电流,直到元件复位。复位电平应为操作电平的97%。当元件复位时,如果W1 Phase INST OC 1 TARGET(W1相位安装OC 1目标)被选择为Latched(锁定),则跳闸和相位LED应保持点亮。否则,只有跳闸指示灯应保持亮起。 重置指示灯并清除信息。7.5.5.4操作时间 使用图7-9中所示的设置:第7-25页的常规测试设置,并启用间隔计时器,将电流水平设置为元件工作水平的1.5倍。 通过闭合双极开关来突然施加电流。 记录操作时间,并将其与S4元素进行比较 相位OC W1相位INST OC 1 W1 PHASE INST OC 1 DELAY设定点值。7.5.5.5 B相和C相元件如果A相元件运行正确且符合规范,则对绕组1的B相和C相位重复上述测试的拾取水平部分。对于相位B,X=H2,Y=G2。对于相位C,X=H3,Y=G3。显示的信息应发生变化,以指示正确的相位、绕组和运行元件。
Pickup level With the interval timer disabled, apply the current signal and increase its magnitude until the trip relay (and all selected auxiliary relays) operate. Compare the measured operating level against the S4 ELEMENTS PHASE OC W1 PHASE INST OC 1 W1 PHASE INST OC 1 PICKUP setpoint. Check that Trip, Pickup, and Phase A(C) LEDs turn on when the element operates. Check that one of the following messages is displayed: LATCHED a: W1 Phase Inst OC 1 or OPERATED a: W1 Phase Inst OC 1Reduce the current until the element resets. The reset level should be 97% of the operate level. When the element resets, the Trip and Phase LEDs should remain on if the W1 PHASE INST OC 1 TARGET was selected as Latched. Otherwise, only the Trip LED should stay on. Reset indicators and clear messages. 7.5.5.4 Operating Time Using the setup shown in FIGURE 7–9: General test setup on page 7– 25 and the Interval Timer enabled, set the current level to 1.5 times the operating level of the element. Apply current suddenly by closing the double-pole switch. Record the operate time and compare it to the S4 ELEMENTS PHASE OC W1 PHASE INST OC 1 W1 PHASE INST OC 1 DELAY setpoint value. 7.5.5.5 Phase B and C Elements If the phase A element performed correctly and met specifications, repeat the pickup level portion of the above test for phases B and C of winding 1. For phase B, X = H2 and Y = G2. For phase C, X = H3 and Y = G3. The displayed message should change to indicate the correct phase, winding, and element that operated.
