XU2-AC  数字测量继电器  通过led显示故障

XU2-AC 电压继电器，是一种数字测量继电器，用于二线，三线和四线系统的监督。它保护发电机，用户或一般设备免受不允许的过压或欠压，可用于低压和中压系统。

此外，还可以监督相序。与传统的保护设备相比，PROFESSIONALLINE的所有继电器都体现了数字保护技术的优越性，具有以下特点:

采用数字数据处理，测量精度高

通过led显示故障

通用宽量程电源提供极宽的工作电压范围

非常精细的分级宽设置范围

通过可改装的串行接口适配器xrs1与过程管理系统进行数据交换

RMS -测量

极短的响应时间

采用smd技术设计紧凑

除此之外，XU2-AC继电器还具有以下特殊功能:

不同开关迟滞可调

过压/欠压监控脱扣时间可单独调节，相序监控可切换

可以测量相对中性点或相对相电压

电压继电器是一种常用的电磁式继电器，用于电力拖动系统的电压保护和控制，在电路中起着自动调节、安全保护、转换电路等作用，主要用于发电机、变压器和输电线的继电保护装置中，作为过电压保护或低电压闭锁的启动原件。

XU2-AC电压继电器包括过电压继电器和欠电压继电器两种，过电压继电器用于设备的过电压保护，其动作阈值为设备额定电压1.05～1.2倍；欠电压继电器用于设备的欠电压保护，其释放整定值为设备额定电压的0.1～0.6倍。

XU2-AC voltage relay is a digital measuring relay for the supervision of two -, three -, and four-wire systems. It protects generators, users or general equipment from impermissible overvoltages or undervoltages and can be used in low and medium voltage systems.

In addition, the phase sequence can be monitored. Compared to traditional protection equipment, all relays in PROFESSIONALLINE demonstrate the advantages of digital protection technology with the following features:

Using digital data processing, the measurement accuracy is high

Fault is indicated by led

Universal wide range power supplies provide an extremely wide operating voltage range

Very fine grading wide setting range

Data is exchanged with the process management system via the retrofit serial interface adapter xrs1

RMS - Measurement

Very short response time

Compact design with smd technology

In addition, the XU2-AC relay has the following special functions:

Different switching hysteresis can be adjusted

The overvoltage/undervoltage monitoring trip time can be adjusted separately, and the phase sequence monitoring can be switched

Relative neutral or relative phase voltage can be measured

Voltage relay is a commonly used electromagnetic relay, used for voltage protection and control of electric drive system, in the circuit plays the role of automatic regulation, safety protection, conversion circuit, etc., mainly used in the relay protection device of generators, transformers and transmission lines, as the starting element of overvoltage protection or low voltage lock.

XU2-AC voltage relays include overvoltage relays and undervoltage relays. Overvoltage relays are used for overvoltage protection of equipment. The operating threshold of the overvoltage relay is 1.05 ~ 1.2 times of the rated voltage of the equipment. The undervoltage relay is used to protect the undervoltage of the equipment, and its release setting value is 0.1 ~ 0.6 times of the rated voltage of the equipment.
