GE Power Management 50:0.025接地CT。还提供用于相位差保护的CT输入。提供的12个RTD输入可以针对不同的RTD类型单独进行现场编程。电压互感器输入允许基于电压和功率量的多种保护功能。四个4至20 mA模拟输入可用于任何传感器输入（如振动、压力、流量等）的跳闸和报警。图1-2：保护特征51过载86过载锁定66启动/小时和启动间隔时间重启块（防反冲计时器）50短路和短路备用机械堵塞37 32欠电流/欠功率反向功率46电流不平衡50G/51G接地故障和接地故障备用87差速49定子RTD 38轴承RTD其他RTD和环境RTD开路RTD报警短路/低RTD 27/59欠压/过压47相位反转81频率无功功率55/78功率因数模拟输入需求报警：A kW kvar kVA SR469自检，维修跳闸线圈监控焊接接触器断路器故障远程开关14速度开关和转速表跳闸减载开关压力开关振动开关19减压启动48过转矩远程启动/停止PROCTLA5.CDR不完整顺序（减压启动）强制继电器操作GE Power Management 469电机管理继电器1-3 1简介1.1概述1故障诊断通过预处理数据、事件记录、跟踪内存和统计信息提供。在发出跳闸之前，469对测量参数进行快照，并将其与跳闸原因一起存储。在行程重置之前，可使用钥匙或通过访问A1状态/最后行程数据实际值来查看行程前数据。469事件记录器可存储多达40个时间和日期戳事件，包括行车前数据。每次发生跳闸时，469存储所有测量的交流电量的跳闸前8个周期和跳闸后8个周期的轨迹。跳闸计数器记录每种类型跳闸的发生次数。还记录RTD和模拟输入的最小值和最大值。这些功能使操作员能够快速确定问题。功率计量作为标准功能内置于469中。下表列出了通过前面板或通信端口可用的计量参数。469配备了3个功能齐全且独立的通信端口。
GE Power Management 50:0.025 Ground CT. CT inputs for phase differential protection are also provided. The 12 RTD inputs provided may be individually field programmed for different RTD types. Voltage transformer inputs allow for numerous protection features based on voltage and power quantities. Four 4 to 20 mA analog inputs may be used for tripping and alarming on any transducer input such as vibration, pressure, flow, etc. Figure 1–2: PROTECTION FEATURES 51 Overload 86 Overload Lockout 66 Starts/Hour & Time Between Starts Restart Block (Anti-Backspin Timer) 50 Short Circuit & Short Circuit Backup Mechanical Jam 37 32 Undercurrent/Underpower Reverse Power 46 Current Unbalance 50G/51G Ground Fault & Ground Fault Backup 87 Differential Acceleration 49 Stator RTD 38 Bearing RTD Other RTD & Ambient RTD Open RTD Alarm Short/Low RTD 27/59 Undervoltage/Overvoltage 47 Phase Reversal 81 Frequency Reactive Power 55/78 Power Factor Analog Input Demand Alarm: A kW kvar kVA SR469 Self-Test, Service Trip Coil Supervision Welded Contactor Breaker Failure Remote Switch 14 Speed Switch & Tachometer Trip Load Shed Switch Pressure Switch Vibration Switch 19 Reduced Voltage Start 48 Over Torque Remote Start/Stop PROCTLA5.CDR Incomplete Sequence (Reduced Voltage Start) Forced Relay Operation GE Power Management 469 Motor Management Relay 1-3 1 INTRODUCTION 1.1 OVERVIEW 1 Fault diagnostics are provided through pretrip data, event record, trace memory, and statistics. Prior to issuing a trip, the 469 takes a snapshot of the measured parameters and stores them with the cause of the trip. This pre-trip data may be viewed using the key before the trip is reset, or by accessing the A1 STATUS / LAST TRIP DATA actual values. The 469 event recorder stores up to 40 time and date stamped events including the pre-trip data. Each time a trip occurs, the 469 stores a trace of 8 cycles pre-trip and 8 cycles post-trip for all measured AC quantities. Trip counters record the number of occurrences of each type of trip. Minimum and maximum values for RTDs and analog inputs are also recorded. These features enable the operator to pinpoint a problem quickly and with certainty. Power metering is built into the 469 as a standard feature. The table below outlines the metered parameters available either through the front panel or communications ports. The 469 is equipped with 3 fully functional and independent communications ports.
