产品详细资料
因此,在抽头变换器位于位置33的情况下,绕组2的CT比必须为1428.6/1才能完全匹配。在这种情况下,失配系数为1428.6/1500=0.952。745允许通过分接位置输入来监控分接开关的位置。利用该输入,745基于抽头变换器设置的实际变压器电压比来动态调整CT比失配因子。分接开关通过安装在变压器箱外部的电机驱动装置进行操作。电机驱动器放置在一个保护壳中,该保护壳包含操作所需的所有设备,包括抽头位置指示电路。该指示电路具有用于每个抽头的端子,每个抽头具有固定的电阻增量。驱动轴上提供局部抽头位置指示的凸轮还控制指示电路中的刮水器端子,如下所示。三相变压器上的相移根据ANSI和IEC标准制造的电力变压器需要识别绕组端子和变压器绕组之间的相位关系。ANSI标准C.37.12.70要求端子的标签包括字符1、2和3,以表示各个阶段的名称。绕组之间的相位关系必须在铭牌上以相量图的形式显示,并清楚地标记绕组端子。
Thus, with the tap changer at position 33, the Winding 2 CT ratio must be 1428.6 / 1 to be perfectly matched. In this case, the mismatch factor is 1428.6 / 1500 = 0.952. The 745 allows monitoring of the tap changer position via the tap position input. With this input, the 745 dynamically adjusts the CT ratio mismatch factor based on the actual transformer voltage ratio set by the tap changer. Tap changers are operated by means of a motor drive unit mounted on the outside of the transformer tank. The motor drive is placed in a protective housing containing all devices necessary for operation, including a tap position indication circuit. This indication circuit has a terminal for each tap with a fixed resistive increment per tap. A cam from the drive shaft that provides local tap position indication also controls a wiper terminal in the indication circuit, as illustrated below.Phase Shifts on Three-phase Transformers Power transformers that are built in accordance with ANSI and IEC standards are required to identify winding terminals and phase relationships among the windings of the transformer. ANSI standard C.37.12.70 requires that the labels of the terminals include the characters 1, 2, and 3 to represent the names of the individual phases. The phase relationship among the windings must be shown as a phasor diagram on the nameplate, with the winding terminals clearly labeled.
