产品详细资料
745变压器保护系统™ 是一种高速、基于多处理器的三相、两绕组或三绕组变压器管理继电器，用于小型、中型和大型电力变压器的初级保护和管理。745将百分比差动、过电流、频率和过励磁保护元件与单个谐波和总谐波失真（THD）的监测结合在一个经济的包中。继电器提供各种自适应继电保护功能：•自适应谐波抑制，可解决浪涌期间的误跳闸问题•自适应时间过电流元件，在提供高次谐波含量的负载电流时，可根据计算的变压器容量调整其拾取设置•多个设定点组，允许用户输入和从多达四组继电器设置中进行动态选择，以满足不同电力系统配置的保护要求•动态CT比率失配校正，可监测有载抽头位置并自动校正CT比率失匹配•FlexLogic™ 这允许将基于逻辑输入和保护元件的PLC式方程分配给745个输出中的任何一个。745还包括强大的测试和模拟功能。这使保护工程师能够根据捕获的或计算机生成的波形数据测试继电器操作，这些波形数据可以转换为数字化格式并下载到745的模拟缓冲区中进行“回放”。还提供了一种波形捕获功能，用于记录故障、浪涌或警报条件的波形数据。自动配置功能消除了对任何特殊CT连接的需要，因为所有CT都以Y形连接。
The 745 Transformer Protection System™ is a high speed, multi-processor based, threephase, two or three winding, transformer management relay intended for the primary protection and management of small, medium and large power transformers. The 745 combines percent differential, overcurrent, frequency, and overexcitation protection elements along with monitoring of individual harmonics, and total harmonic distortion (THD) in one economical package. The relay provides a variety of adaptive relaying features: • Adaptive harmonic restraint which addresses the problem of false tripping during inrush • Adaptive time overcurrent elements which will adjust their pickup settings based on the calculated transformer capability when supplying load currents with high harmonic content • Multiple setpoint groups which allow the user to enter and dynamically select from up to four groups of relay settings to address the protection requirements of different power system configurations • Dynamic CT ratio mismatch correction which monitors the on-load tap position and automatically corrects for CT ratio mismatch • FlexLogic™ which allows PLC style equations based on logic inputs and protection elements to be assigned to any of the 745 outputs. The 745 also includes a powerful testing and simulation feature. This allows the protection engineer the ability to test the relay operation based on captured or computer generated waveform data which can be converted to a digitized format and downloaded into the 745’s simulation buffer for “playback”. A waveform capture function that records waveform data for fault, inrush, or alarm conditions is also provided. The auto-configuration function eliminates the need for any special CT connections by having all CTs connected in wye.
