摘要： Embodiments of the disclosure pertain to a voltage regulator system having a voltage regulation controller and a transformer assembly. The transformer assembly includes a coil winding, a multi-contact tap arrangement connected to the coil winding, and a multifurcated tap changer system that includes a first tap changer having a contactor element which makes contact with a first contact of the multi-contact tap arrangement when the controller provides a positioning stimulus based on sensing a voltage deviation from a nominal output voltage of the voltage regulator system. The multifurcated tap changer system further includes a second tap changer that is mechanically ganged to the first tap changer and includes another contactor element arranged to automatically make contact with a second contact of the multi-contact tap arrangement when the contactor element of the first tap changer makes contact with the first contact of the multi-contact tap arrangement.

摘要： Automatically changing the tap position in a load tap changer includes noting a polarity of a first tap position of a load tap changer. A duration for which one or more consecutive tap positions of the load tap changer collectively have had the noted polarity also is noted. The one or more consecutive tap positions include the first tap position. The duration for which the one or more consecutive tap positions collectively have had the noted polarity is compared to a threshold value. A change is made from the first tap position to a second tap position with a polarity that is different than the noted polarity when the duration for which the one or more consecutive tap positions collectively have had the noted polarity is longer than the threshold value. A change may be made from the second tap position back to the first tap position.

摘要： A tap changer including a tap positionable to vary the winding ratio of the transformer in response to changes in an electric load on the transformer is disclosed herein. The transformer includes an electric drive which is responsive to raise or lower signals applied thereto in order to selectively position the tap by the raising or lowering of the tap and thereby raising or lowering the transformer winding ratio. Upon sensing the current of the motor control signals, an up/down counter is incremented or decremented. Accordingly, when a tap change signal is detected, the direction of tap changer movement may be determined, based upon the value of the up/down counter. In this way the tap position is also accurately determined and known.
摘要翻译： 本文公开了一种分接开关，其包括可分接位置以根据变压器上的电负载变化来改变变压器的绕组比。 变压器包括电驱动器，其响应于施加到其上的信号的升高或降低，以便通过提升或降低抽头来选择性地定位抽头，从而提高或降低变压器绕组比。 一旦检测到电机控制信号的电流，增/减计数器就会递增或递减。 因此，当检测到抽头变换信号时，可以基于上/下计数器的值来确定抽头切换器移动的方向。 以这种方式，也可以精确地确定和知道抽头位置。
