GE UR8CH 安装在通用继电器中 电流互感器

【产品详情】

产品描述

General Electric Multilin 的 UR-8CH 是一款 CT/VT 模块，设计用于安装在通用继电器中，作为系统的替代品或升级。该模块为继电器提供 3-1A/5A 相位 CT 和 1/5A 接地 CT。

除了提供有关电力系统的数据外，电流互感器还能够将系统与极端电流和电压隔离开来，从而延长系统寿命并降低一般维护成本。此外，电流互感器提供标准化的输出电压，无需额外的辅助保护。电压互感器还提高了用户的安全性，并能可靠地测量电力系统电压。

CT/VT 设置可以高度修改以创建独特的保护方案，从而增加模块的多功能性。这些方案包括差动保护、并发分相保护等。该模块某些版本的增强诊断功能能够验证模拟信号的完整性，采用先进的算法来保证可靠性。此功能与 UR 继电器的健康诊断功能相结合，可提供双层评估，以确保组件功能正常。

关于 UR-8CH 的常见问题

如何确定其通用继电器中包含的特定固件？

UR 系列 Multilin GE 通用继电器具有 EnerVista lauchpad 软件包，用于管理和编程通用继电器。每个继电器都包含该软件，该软件允许操作员管理可编程设定点和设定点文件。固件也可以通过该软件访问，以跟上最新版本。固件版本可能会影响特定继电器中的 CT/VT 模块和 CPU。例如，多年来，新的 CT/VT 模块和新的 CPU 已经发布，用于更广泛的通用继电器 Multilin 系列。使用 4.0x 及更高版本的固件，可以实现与硬件的兼容性。具体而言，新的 CT/VT 模块和 CPU 必须一起包含在固件为 4.0 倍或更新的同一通用继电器中。同样，旧版本的 CPU 和 CT/VT 模块与 3.5x 或更早的固件版本兼容。如果通用继电器中包含 UR-8CH CT/VT 模块，则无论特定继电器的功能如何，继电器的固件版本可能为 3.5 倍或更低，因为 UR-8CH 是 CT/VT 模块的旧订购代码。

Product description

General Electric Multilin's UR-8CH is a CT/VT module designed to be installed in general-purpose relays as a system replacement or upgrade. This module provides 3-1A/5A phase CT and 1/5A ground CT for relays.

In addition to providing data about the power system, current transformers are able to isolate the system from extreme currents and voltages, extending system life and reducing general maintenance costs. In addition, current transformers provide standardized output voltages without additional auxiliary protection. Voltage transformers also improve user safety and reliably measure power system voltage.

CT/VT Settings can be highly modified to create unique protection schemes, thereby increasing the versatility of the module. These schemes include differential protection, concurrent split phase protection and so on. Some versions of the module have enhanced diagnostic capabilities to verify the integrity of analog signals, using advanced algorithms to ensure reliability. This function, combined with the UR relay's health diagnostic function, provides a two-layer assessment to ensure that components are functioning properly.

Frequently Asked questions about UR-8CH

How do I determine which specific firmware is included in my universal relay?

The UR Series Multilin GE Universal relays feature the EnerVista lauchpad software package for managing and programming universal relays. Each relay includes the software, which allows the operator to manage programmable set points and set point files. Firmware can also be accessed through the software to keep up with the latest version. Firmware versions may affect CT/VT modules and cpus in specific relays. For example, over the years, new CT/VT modules and new cpus have been released for use in the broader Multilin family of general-purpose relays. With firmware versions 4.0x and higher, hardware compatibility can be achieved. Specifically, the new CT/VT module and CPU must be included together in the same universal relay with 4.0 times or newer firmware. Similarly, older versions of the CPU and CT/VT modules are compatible with firmware versions of 3.5x or earlier. If the UR-8CH CT/VT module is included in the general purpose relay, the firmware version of the relay may be 3.5x or lower, regardless of the function of the particular relay, because UR-8CH is the old order code for the CT/VT module.
