UR8MH GE 通用继电器 增强的诊断功能

【产品详情】

GE Multilin的UR-8MH是一种CT / VT模块，可为通用继电器提供灵敏的接地4CT / 4VT和增强的诊断功能。“VT”代表电压互感器，而“CT”代表“电流互感器”，表示模块能够将电压和电流额定值缩小到太高，继电器无法监控和管理。安装模块后，继电器可以提供有价值的电流和电压数据，并利用这些数据来响应电力系统内的变化条件。

通用继电器手册提供了有关正确连接程序的更多信息，提供了最大效率的图表和指南。通常，CT/VT 模块可以在通道 1 到 4 或通道 5 到 8 上具有电压输入（包括通道 1 和 5），通道 2 和 6 连接到相位 B，依此类推。

UR-8MH模块用途广泛，可针对多种工艺和方案进行配置。例如，如果需要电力系统，用户可以建立并发分相保护和差动保护。继电器的可修改性允许根据用户独特的系统要求进行定制，无论是通过各种接线布置还是通过编辑继电器设置。

关于UR-8MH的常见问题

通用继电器的不同 CT/VT 模块的用途是什么？

通用继电器中使用的 CT/VT 模块有多种订购号。一些CT/VT模块可以通过订购号的使用年限来区分。例如 8A、8B、8C 和 8D被认为是原始模型。对于某些优傲继电器（如 F35），具有较旧的 CT/VT 模块意味着 CPU 也必须是旧型号的。否则，继电器的显示屏上只会出现错误代码。UR-8MH专门具有具有增强诊断功能的敏感接地4CT / 4VT。这种额外的敏感接地选项允许通用继电器具有接地故障保护。CT/VT 模块的某些订单变体不附带此选项。不同的CT/VT模块允许最终用户实现多种独特的方案，如差动保护或并发分相方案。继电器间通信模块还有助于UR继电器之间的模拟值或数字状态通信。每个可变选项都使最终用户能够通过各种订单规格定制其通用继电器，以实现最适合其手头用途的优傲继电器。

【英文介绍】

GE Multilin's UR-8MH is a CT/VT module that provides sensitive grounded 4CT / 4VT and enhanced diagnostic capabilities for general-purpose relays. "VT" stands for voltage transformer, while "CT" stands for "current transformer," indicating that the module is able to narrow the voltage and current ratings to too high for the relay to monitor and manage. When the module is installed, the relay can provide valuable current and voltage data and use this data to respond to changing conditions within the power system.

The General Relay Manual provides more information on proper connection procedures, providing charts and guidelines for maximum efficiency. Typically, a CT/VT module can have voltage inputs on channels 1 to 4 or channels 5 to 8 (including channels 1 and 5), channels 2 and 6 connected to phase B, and so on.

The UR-8MH module is versatile and can be configured for a variety of processes and scenarios. For example, if a power system is required, users can establish concurrent split phase protection and differential protection. The modifiability of relays allows customization to the user's unique system requirements, whether through various wiring arrangements or by editing relay Settings.

Frequently Asked Questions about UR-8MH

What is the purpose of the different CT/VT modules of the universal relay?

CT/VT modules used in general purpose relays are available in a variety of ordering numbers. Some CT/VT modules can be distinguished by the age of the order number. For example, 8A, 8B, 8C, and 8D are considered original models. For some UOs relays, such as the F35, having an older CT/VT module means the CPU must also be an older model. Otherwise, only error codes will appear on the display of the relay. The UR-8MH is specially equipped with a sensitive grounded 4CT / 4VT with enhanced diagnostic capabilities. This additional sensitive grounding option allows universal relays to have ground fault protection. Some order variants of CT/VT modules do not come with this option. Different CT/VT modules allow end users to implement a variety of unique schemes, such as differential protection or concurrent phase separation schemes. The relay-to-relay communication module also facilitates analog value or digital status communication between UR relays. Each variable option enables end users to customize their universal relays through various order specifications to achieve the best fit for their application at hand.
