GE UR8ZH CT/VT 模块 识别和调节的值

【产品详情】

产品描述

通用电气 Multilin 的 GE UR8ZH 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，因为变压器的次级绕组的一部分必须接地。此外，它们还允许识别和纠正可能在系统内产生不安全条件的故障。最后，所提供的数据使用户能够确保为机器和整个电网提供足够的保护。

与 CT 和 VT 相关的设置可以在 EnerVista UR 中修改，EnerVista UR 是通用电气 Multilin 的软件程序，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、简化的用户界面。该程序还可以对系统生成的数据进行趋势分析和导出，使用户能够更好地评估系统趋势。

关于 GE UR8ZH 的常见问题

GE UR8ZH可以配置多少个信号来监控通用Multilin继电器的电源线？

GE通用Multilin继电器系统具有一个综合单元，包括CPU、CT/VT模块、I/O传感器、数字I/O和其他组件。CT/VT 模块组件具有多种具有独特特性的订购号。每个 CT/VT 模块最多可配置 24 个模拟 CT 和 VT 信号，用于监控电力线。CT/VT 模块接受 1 个或 5 个电流互感器。UR-8AH 是较旧的 CT/VT 模块，接受 3.5 倍或更早的固件。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 模块匹配，例如 UR-9A、UR-9C 或 UR-9D 模块。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。

Product description

GE Multilin's GE UR8ZH is a CT/VT module in the general purpose relay family that provides a 1A/5A phase CT, a 1A/5A ground CT, and 4 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 winding must be grounded. In addition, they allow the identification and correction of failures that can create unsafe conditions within the system. Finally, the data provided enables users to ensure adequate protection for machines and the grid as a whole.

The Settings associated with CT and VT can be modified in EnerVista UR, a software program from GE Multilin that 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 perform trend analysis and export on the data generated by the system, enabling users to better evaluate system trends.

Common questions about GE UR8ZH

How many signals can the GE UR8ZH configure to monitor the power cord of a universal Multilin relay?

The GE Multilin relay system features an integrated unit that includes a CPU, CT/VT module, I/O sensor, 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 accept 1 or 5 current transformers. The UR-8AH is an older CT/VT module that accepts 3.5x or older firmware. 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 the Multilin CPU module, such as the UR-9A, UR-9C, or UR-9D module. 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.
