O3EC HENF442581R1模块卡件

产品详情资料

将该设定点编程为“否”可确保电机跳闸，只有在总线重新通电后才能重新启动。如果启用了欠压报警或跳闸功能，一旦运行时Va、Vb或Vc的幅值低于拾取电平，或启动时启动拾取电平（延迟指定的时间段），将发生跳闸或报警（拾取电平是电机铭牌电压的倍数）。当电机停止且U/V ACTIVE ONLY IF BUS ENERGIZED（仅当总线通电）设定点编程为“否”时，运行拾取水平也适用。在恒定负载下运行的电机上的欠压会导致电流增加。继电器热模型通常会发现这种情况并提供充分的保护。然而，该设置点可与时间延迟一起使用，以提供额外的保护，该保护可编程为跳闸提前警告。当电源电压已经下降时，尝试启动大型电机也可能是不可取的。启动电机时持续存在的严重欠压可能会阻止电机达到额定转速。Programming "No" for this setpoint ensures that the motor is tripped and may be restarted only after the bus is re-energized. If the undervoltage alarm or trip feature is enabled, once the magnitude of either Va, Vb, or Vc falls below the pickup level while running or starting pickup level while starting (for a period of time specified by the delay), a trip or alarm will occur (pickup levels are multiples of motor nameplate voltage). The running pickup level also applies when the motor is stopped and the U/V ACTIVE ONLY IF BUS ENERGIZED setpoint is programmed to "No". An undervoltage on a running motor with a constant load results in increased current. The relay thermal model typically picks up this condition and provides adequate protection. However, this setpoint may be used in conjunction with the time delay to provide additional protection that may be programmed for advance warning by tripping. Attempting to start a large motor when the supply voltage is already down may also be undesirable. An undervoltage of significant proportions that persists while starting a motor may prevent the motor from coming up to rated speed.
