SR745-W2-P5-G5-HI-A 变压器保护继电器

SR745-W2-P5-G5-HI-A 变压器保护继电器

产品描述
作为通用电气 Multilin 745 系列的一部分，745-W2-P5-G5-HI-A 是一款变压器保护继电器，可作为自动化变电站的独立单元或组件。该器件利用高度可配置的设定点来监控、记录和响应变压器、自耦变压器和/或电抗器中不断变化的条件。由于变压器保护系统具有内置计量功能，因此该装置有助于降低与辅助计量设备相关的成本。

745-W2-P5-G5-HI-A 是该型号的每相两绕组版本。两个绕组的相电流输入额定值均为 5A，由型号中的“P5”修饰符表示。该版本的器件还包括模拟输入/输出，这是基本型号的附加功能。可选的通用传感器输入可以监控用户设定的数量，然后可用于GE Multilin的745继电器的保护功能。

这种特殊型号的 745 带有 7 个传感器输出通道，可单独编程为 4 至 20mA、0 至 20mA、1 至 10mA 和 0 至 1mA 的范围。745-W2-P5-G5-HI-A 与低功率同类产品不同，提供 90 至 300 VDC 的控制功率范围;48 至 62 Hz 时为 70 至 265 VAC，而不是 20 至 60 VDC;20 至 48 VAC，48 至 62 Hz。这使其成为高控制电力变压器系统的zui佳选择。

Product description
Part of the General Electric Multilin 745 series, the 745-W2-P5-G5-HI-A is A transformer protection relay that can be used as a stand-alone unit or component in an automated substation. The device utilizes highly configurable set points to monitor, record, and respond to changing conditions in transformers, autotransformers, and/or reactors. Since the transformer protection system has a built-in metering function, the device helps to reduce the costs associated with auxiliary metering equipment.

745-W2-P5-G5-HI-A is a two-winding per phase version of this model. The phase current input rating for both windings is 5A, indicated by the "P5" modifier in the model number. This version of the device also includes analog input/output, which is an additional feature of the basic model. An optional universal sensor input can monitor user-set quantities and can then be used for the protection function of GE Multilin's 745 relays.

This special model 745 comes with seven sensor output channels that can be individually programmed for ranges of 4 to 20mA, 0 to 20mA, 1 to 10mA, and 0 to 1mA. The 745-W2-P5-G5-HI-A differs from its low-power counterparts by offering a control power range of 90 to 300 VDC; 70 to 265 VAC at 48 to 62 Hz instead of 20 to 60 VDC; 20 to 48 VAC, 48 to 62 Hz. This makes it the best choice for high-control power transformer systems.
