UR8LH GE  专为通用继电器系列设计的CT / VT模块 UR-8LH

【产品详情】

产品描述

通用电气Multilin的UR-8LH是专为通用继电器系列设计的CT / VT模块。该模块可用于替换当前模块、升级当前模块或为最初未随给定模块提供的通用继电器提供新功能。该特殊模块为继电器提供 4CT/4VT 和增强的诊断功能。

UR-8LH模块的这种变体配备了增强的诊断功能，为电力系统提供了许多好处。首先，该模块能够验证模拟信号的完整性并确保可靠性。该模块通过采用高级算法来实现这一点，该算法可以确定信号是否正常工作。

CT/VT 变压器将电流值和电压值缩小到继电器可以处理的数量，从而计算出输出与电流和电压相关的值的比率。此功能对于识别系统内的危险电压和电流条件以及建立适当的响应至关重要。这些数据可以通过前面板的液晶显示器或运行 EnerVista UR 软件程序的计算机查看。

关于 UR-8LH 的常见问题

UR-8LH 是一些通用继电器中的 CT/VT 模块（电流互感器和电压互感器）。每个通用继电器包含一个 CT/VT 模块、一个 CPU、一个电源、一个 IEC 过程总线、继电器间通信、一个通信开关、一个数字 I/O 和一个传感器 I/O。CT/VT 模块可包含多达 24 个信号，用于交流电源线的监控功能。一些CT/VT模块甚至具有敏感的接地输入，用于接地故障保护。如果是这种情况，订货号名称将为设备提供此功能。Multilin UR-8LH的订单规格包括标准的4CT / 4VT特性，但具有增强的诊断功能。8G、8J、8M 和 8R CT/VT 模块具有灵敏的接地故障保护功能。UR-8LH 是一个新的模块 CT/VT，因此它应该与新的 CPU 配对以避免硬件不匹配错误。至少 4.0x 的固件版本与新的 CPU 和新的 CT/VT 模块兼容。相比之下，通用继电器需要 3.4x 或更早固件版本的固件版本才能与较旧的 CPU 和 CT/VT 模块兼容。

【英文介绍】

Product description

The UR-8LH from GE Multilin is a CT/VT module designed for the general purpose relay family. This module can be used to replace the current module, upgrade the current module, or provide new functionality for generic relays not originally supplied with a given module. This special module provides 4CT/4VT and enhanced diagnostic capabilities for relays.

This variant of the UR-8LH module is equipped with enhanced diagnostic capabilities that provide many benefits to power systems. First, the module is able to verify the integrity of the analog signal and ensure reliability. The module does this by adopting advanced algorithms that can determine if the signal is working properly.

The CT/VT transformer narrates the current and voltage values to the number that the relay can handle, thereby calculating the ratio of the output value to the current and voltage. This function is essential for identifying dangerous voltage and current conditions within the system and establishing an appropriate response. This data can be viewed through the LCD display on the front panel or the computer running the EnerVista UR software program.

Frequently Asked Questions about UR-8LH

UR-8LH is a CT/VT module (current transformer and voltage transformer) in some general purpose relays. Each universal relay consists of a CT/VT module, a CPU, a power supply, an IEC process bus, relay to relay communication, a communication switch, a digital I/O, and a sensor I/O. The CT/VT module can contain up to 24 signals for AC power line monitoring functions. Some CT/VT modules even have sensitive ground inputs for ground fault protection. If this is the case, the order number name will provide this function for the device. The order specifications for the Multilin UR-8LH include standard 4CT / 4VT features, but with enhanced diagnostic capabilities. The 8G, 8J, 8M and 8R CT/VT modules feature sensitive ground fault protection. UR-8LH is a new module CT/VT, so it should be paired with the new CPU to avoid hardware mismatch errors. Firmware versions of at least 4.0x are compatible with new cpus and new CT/VT modules. In contrast, general-purpose relays require firmware versions of 3.4x or earlier firmware versions to be compatible with older cpus and CT/VT modules.
