GE UR8FV 四端电压互感器

【产品详情】

通用电气Multilin的UR-8FV旨在更换旧模块或升级现有的通用继电器系统，是一种CT / VT模块，可为该继电器提供3-1A / 5A相CT，1A / 5A接地CT和四端电压互感器。 该模块对于监控和管理交流电力线至关重要，还可以提高用户和电力系统设备的总体安全性。

有关如何正确连接模块的信息可以在大多数通用继电器手册中找到，这些手册提供了重要的细节和警告，可以确定安装是否成功。买家最常使用 12 号美国线规 （AWG） 来连接模块，尽管继电器最多接受 10 号美国线规。

通用电气Multilin为通用继电器系列生产了大量的CT / VT模块，因此建议买家在购买前适当研究所有选项。一些模块包括灵敏的地面保护和增强的诊断等功能，这对于高要求系统特别有用。灵敏的接地输入模块提供的灵敏度是其各自非灵敏对应模块的地面CT输入的十倍。

关于 UR-8FV 的常见问题

UR-8FV是新的CT / VT模块。它的特点是具有标准的4CT / 4VT。相比之下，其他 CT/VT 模块可能具有标准或灵敏的 8CT 或带有增强型显示器的标准或灵敏 4CT/4VT。某些CT/VT模块的敏感特性使其能够为通用继电器提供接地故障保护。它们能够在存在具有高阻抗特性的接地系统的情况下获取敏感的接地输入，从而具有这一优势。所有 CT/VT 模块都能够为通用继电器提供多达 24 个 CT 和 VT 信号（模拟），以增强其对电力线的监控能力。附加的特殊功能模块还可以检测由导体掉落情况引起的故障。重要的是，旧的CT / VT模块放置在通用继电器中，该继电器也具有较旧型号的CPU。同样，将新的CT / VT模块与新的CPU相匹配也很重要，以避免显示器上的错误指示器。较旧的型号在 RH-8 之后将具有较低的字母数字代码（例如 RH-8A）。

【英文介绍】

Designed to replace an older module or upgrade an existing general-purpose relay system, GE Multilin's UR-8FV is a CT/VT module that provides a 3-1A / 5A phase CT, 1A / 5A ground CT, and four-terminal voltage transformer for this relay. This module is essential for monitoring and managing AC power lines and also improves the overall safety of users and power system equipment.

Information on how to properly connect modules can be found in most general purpose relay manuals, which provide important details and warnings that can determine whether the installation was successful. Buyers most often use 12 gauge American Wire (AWG) to connect modules, although relays accept up to 10 gauge American wire.

Ge Multilin produces a large number of CT/VT modules for the general purpose relay family, so buyers are advised to properly research all options before purchasing. Some modules include features such as sensitive ground protection and enhanced diagnostics, which are particularly useful for demanding systems. The sensitive ground input modules provide ten times more sensitivity than the ground CT inputs of their respective non-sensitive counterparts.

Frequently Asked questions about UR-8FV

UR-8FV is the new CT/VT module. It features a standard 4CT / 4VT. In contrast, other CT/VT modules may have standard or sensitive 8CT or standard or sensitive 4CT/4VT with enhanced displays. The sensitive nature of some CT/VT modules enables them to provide ground fault protection for general purpose relays. They have this advantage by being able to obtain a sensitive grounding input in the presence of a grounding system with high impedance characteristics. All CT/VT modules are capable of providing up to 24 CT and VT signals (analog) for universal relays to enhance their ability to monitor power lines. Additional special function modules can also detect faults caused by conductor drop conditions. Importantly, the old CT/VT module is placed in a general purpose relay that also has an older model CPU. Similarly, it is important to match the new CT/VT module with the new CPU to avoid false indicators on the display. Older models will have a lower alphanumeric code after RH-8 (e.g. RH-8A).
