GE UR8FV  CT/VT 模块 通用继电器系统

【产品详情】

产品描述

通用电气 Multilin 的 UR-8FV 是一种 CT/VT 模块，旨在替换旧模块或升级现有的通用继电器系统，为继电器提供 3-1A/5A 相位 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，这些手册提供了可以确定安装是否成功的重要细节和警告。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。其中一些模块包括敏感的接地保护和增强的诊断等功能，这对于高要求系统特别有用。敏感接地输入模块的灵敏度是其各自非敏感模块上的接地 CT 输入的 10 倍。

关于 UR-8FV 的常见问题

UR-8FV 是新型 CT/VT 模块的一部分。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 或标准或灵敏的 4CT/4VT，并具有增强的显示。某些 CT/VT 模块的敏感特性使它们能够为通用继电器提供接地故障保护。它们能够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，从而实现这一优势。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），以提高其对电力线的监控能力。附加的特殊功能模块可以额外检测由导体掉落情况引起的故障。重要的是，旧的 CT/VT 模块应放置在一个通用继电器中，该继电器也具有旧型号的 CPU。同样，将新的 CT/VT 模块与新的 CPU 相匹配也很重要，以避免显示屏上的错误指示器。旧型号在 RH-8（例如 RH-8A）之后将具有较低的字母数字代码。

Product description

Ge Multilin's UR-8FV is a CT/VT module designed to replace an older module or upgrade an existing general-purpose relay system with a 3-1A/5A phase CT, 1A/5A ground CT, and four-terminal voltage transformer for the 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 the success of an installation. 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 of these modules include features such as sensitive ground protection and enhanced diagnostics, which are particularly useful for demanding systems. The sensitive ground input modules are 10 times more sensitive than the ground CT inputs on their respective non-sensitive modules.

Frequently Asked questions about UR-8FV

The UR-8FV is part of 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 display. The sensitive nature of some CT/VT modules enables them to provide ground fault protection for general purpose relays. They achieve this advantage by being able to obtain sensitive ground inputs in the case of ground systems with high impedance characteristics. All CT/VT modules are capable of providing up to 24 CT and VT signals (analog) for universal relays to improve their ability to monitor power lines. Additional special function modules allow additional detection of faults caused by conductor drop conditions. It is important that the older CT/VT module be 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).
