关于269PLUS-100N-120的常见问题

269PLUS-100N-120 Multilin 269PLUS数字电机管理和保护继电器的一些保护特性是什么?

269PLUS-100N-120 Multilin GE继电器设计用于保护中型工业交流电机及其机械系统。当电机加速到全速运行时，电机在运行和启动条件下由269PLUS-100N-120提供保护。如果电机过载，如果启动之间的时间不够，或者如果加速时间或每小时启动不理想，那么根据特定的电机可能会发生报警或跳闸。

对于Multilin GE电机管理269PLUS-100N-120数字继电器，什么是不平衡负序电源电压?

269PLUS-100N-120 Multilin GE继电器用于电机管理和保护，提供防止不平衡或缺相的保护。电源电压不平衡是指负序电流大幅增加。这种情况会导致高转子加热，从而缩短转子的寿命。269PLUS-100N-120 Multilin GE数字继电器将计算负序和正序电流之间的比率，以产生a

269PLUS-100P-120 is a motor management relay that is manufactured by GE Multilin. This relay is 100 Ohm and has a platinum RTD. The shipping box is 11.40 inches x 7.50 inches x 16.00 inches (W x H x D). The shipping weight is 7.75 lb. The ambient temperature for storage and operation must fall between -25°C-60°C. Applications of the relay include statistical record-keeping and communication with programmable controllers and computers for integrated plant control. The operational features on the relay are that the relay is microcomputer-controlled and keypad programmable. When installing this relay, remember to follow all national and local electrical codes.

This relay is designed for applications that require medium-sized motors. The protection and control features on this unit include

pre-trip alarm warnings
emergency restart capability
2 auxiliary relays
latched main trip relay
alarm relay
variable lock-out time
phase reversal
ground fault
short-circuit protection
unbalance/single phasing
trip/mechanical jam
locked rotor
undercurrent for load loss
user-defined overload FlexCurve
8 standard overload curves

The unit also offers motor multiple starts, stator winding and bearing overtemperature, and a thermal model biased with RTD and negative sequence current feedback. The monitoring and metering features on the drive include optional voltage and power metering, learned and statistical data, data logger, and current and thermal capacity metering. On the drive, there are 12 programmable RTDs, 5 factory-programmed digital inputs, 4 output relays, and 1 programmable analog output. The drive uses EnerVista software.
