GE UR8AH CT/VT模块 电压互感器

【产品详情】

通用电气Multilin的UR-8AH是通用继电器系列的CT/VT模块，为UR继电器提供1A/5A相位CT、1A/5A接地CT和4个电压互感器。电压互感器和电流互感器将电力系统的电压和电流值缩小到通用继电器可以识别和调节的值。

该模块还提高了操作员的整体安全性，因为变压器次级绕组的一部分必须接地。此外，它们还允许故障识别和纠正，这些故障可能会在系统内产生不安全的情况。最后，所提供的数据使用户能够确保为整个机器和电网提供足够的保护。

与CT和VT相关的设置可以在通用电气Multilin的软件程序EnerVista UR中修改，该程序与通用继电器系列兼容。虽然所有通用继电器都有一个基本的键盘和LCD，用于导航系统设置和数据值，但EnerVista UR为系统配置和数据审查提供了改进的简化用户界面。该程序还可以趋势和导出系统生成的数据，使用户能够更好地评估系统趋势。

关于 UR-8AH 的常见问题

UR-8AH可以配置多少个信号来监控通用Multilin继电器的电源线？

通用Multilin继电器的GE系统具有一个全面的单元，其中包含CPU，CT / VT模块，I / O传感器，数字I / O和其他组件。CT/VT 模块组件具有各种具有独特特性的订购号。每个 CT/VT 模块最多可以配置 24 个模拟 CT 和 VT 信号，用于监控电力线。CT/VT 模块可接受 1 或 5 个电流互感器。UR-8AH是较旧的CT / VT模块，接受3.5x或更早的固件。它被描述为具有标准的4CT / 4VT，类似于新版本CT / VT（UR-8F）。UR-8AH CT/VT 模块应与旧版本的 Multilin CPU 模块（如 UR-9A、UR-9C 或 UR-9D 模块）匹配。UR 系列 Multilin 通用继电器系统的所有其他组件都与较新版本的 CT/VT 模块和新 CPU 兼容，例如 UR F35 继电器。Multiln 通用继电器系统记录的其他一些交流信号包括电压、功率、电流、能量、频率和需求。这些变量中的每一个都以高精度计量，作为每个 UR 中包含的标准。

【英文介绍】

Ge Multilin's UR-8AH is a CT/VT module in the general purpose relay family that provides a 1A/5A phase CT, a 1A/5A ground CT, and four voltage transformers for UR relays. Voltage transformers and current transformers narrow the voltage and current values of a power system to a value that a general purpose relay can recognize and regulate.

The module also improves the overall safety of the operator, as part of the transformer's secondary windings must be grounded. In addition, they allow for the identification and correction of faults that could create unsafe conditions within the system. Finally, the data provided enables users to ensure adequate protection for the entire machine and the grid.

The Settings associated with CT and VT can be modified in GE Multilin's software program EnerVista UR, which is compatible with the general purpose relay family. While all general-purpose relays have a basic keyboard and LCD for navigating system Settings and data values, EnerVista UR offers an improved simplified user interface for system configuration and data review. The program can also trend and export data generated by the system, enabling users to better evaluate system trends.

Frequently Asked Questions about UR-8AH

How many signals can the UR-8AH be configured to monitor the power cord of a universal Multilin relay?

GE systems with universal Multilin relays feature a comprehensive unit that contains CPU, CT/VT modules, I/O sensors, digital I/O and other components. CT/VT module components are available in a variety of ordering numbers with unique characteristics. Each CT/VT module can be configured with up to 24 analog CT and VT signals for monitoring power lines. CT/VT modules can accept 1 or 5 current transformers. The UR-8AH is an older CT/VT module that accepts firmware of 3.5x or earlier. It is described as having a standard 4CT / 4VT, similar to the new version CT/VT (UR-8F). The UR-8AH CT/VT module should match older versions of Multilin CPU modules such as UR-9A, UR-9C, or UR-9D modules. All other components of the UR Series Multilin universal relay system are compatible with newer versions of CT/VT modules and new cpus, such as the UR F35 relay. Some of the other AC signals recorded by Multiln universal relay systems include voltage, power, current, energy, frequency, and demand. Each of these variables is measured with high precision as the standard included in each UR.
