XU2-AC 数字测量继电器

电压继电器，类型XU2-AC，专业线，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，PROFESSIONAL LINE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:
•数字数据处理，测量精度高
•通过led显示故障•通过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
•紧凑设计的smd技术
除此之外，XU2-AC继电器还具有以下特殊功能:
•不同的开关迟滞可调
•过压/欠压监控的脱扣时间单独可调
•相序监督可切换
•测量相对中性点或相对相电压可能

XU2-AC

XU2-AC 数字测量继电器

The voltage relay, type XU2-AC, of the PROFESSIONAL LINE, is a digital measuring relay for thesupervision of two, three and four wire systems. It protects electrical power generators, consumersor general equipment against inadmissible overvoltage or undervoltage and can be used for lowvoltage and for medium voltage systems.

In addition it is possible to supervise the phase sequence

When compared to conventional protection equipment all relays of the PROFESSIONAL LINE reflect the superiority of digital protection techniques with the following features:
• High measuring accuracy by digital data processing
• Fault indication via LEDs• Extremely wide operating ranges of the supply voltage by universal wide rangepower supply
• Very fine graded wide setting ranges
• Data exchange with process management system by serial interface adapter XRS1which can be retrofitted
• RMS – measurement• Extremely short response time
• Compact design by SMD-technology
In addition to this relay XU2-AC has the following special features:
• Different switching hysteresis adjustable
• The tripping periods for overvoltage/undervoltage supervision separately adjustable
• Phase sequence supervision switchable
• Measurement phase-to-neutral or phase-to-phase voltage possible
