摘要： A tap selector for a power transformer switchable under load is monitored by detecting the effective values of current and voltage of the drive motor of the tap changer. The power is calculated and from that the instantaneous torque and the latter is compared with setpoint values either of the torque and position of the tap selector or in terms of characteristic segments of the torque versus time graph with normalized segments of a setpoint graph so that, with serious deviation an immediate shutdown of tap selector operations is ensured or information can be generated as to trends or the need for maintenance.

摘要： The invention relates to a step switch. Two vacuum switchgear cells (34, 35) are provided as electrical switching means. The fixed selector contacts (n) are arranged alternately in parallel strips and are interconnectedy means of two moveable mechanical contacts (8, 9) existing in a fixed relationship to each other. A mechanical changeover contact (28) is actuated by means of an energy storage mechanism that is triggered after a prior lifting movement and both vacuum switchgear cells (34, 35) for each phase are simultaneously actuated.

摘要： A position indicator for a motor drive for actuating a step switch, tap changer, or dipping coil, has a display board having front and back faces and a first circular array of symbols on the front face corresponding to individual switching phases traversed during changeover of the motor drive from one operational position into another neighboring operational position. A first shaft extending through the board centrally of the first array and defining a first axis carries a pointer at the front face rotatable about the first axis through positions aligned with the symbols. A second circular array of symbols on the front face is associated with individual possible stationary operational positions of the step switch, the tap changer, or the dipping coil. A second pointer shaft projecting through the board centrally of the second array and defining a second axis carries a second pointer at the front face rotatable about the second axis through positions aligned with the symbols of the second array. Respective trailing pointers pivotal on the second axis and not driven by the second shaft flank the second pointer and have entrainment formations engageable therewith. Thus as the second pointer moves and engages either of the pointers it displaces same. A gear mechanism on the back face connects the second shaft to the first shaft for movement of the second pointer angularly codirectionally with the first pointer between adjacent symbols of the second display on rotation of the first pointer through 360°.

摘要： The invention relates to a selector switch for tapped transformers to enable continuous tap switching with respect to a tapped winding, whereby fixed stepped contacts are arranged inside a cylinder made of insulating material on a horizontal plane for each phase. A rotating actuating shaft is located inside the insulating cylinder. The actuating shaft has a moveable hinged contact carrier for each phase that is to be switched and vacuum switching cells are respectively and vertically arranged on said contact carrier.

摘要： The invention relates to a method by which measured valuerelevant for functioning corresponding to the respective positionof the stepping switch during the switching is registered and isdistributed in subsequent individual sections which during onereswitching correspond to functions occurring one after the other.Within the framework of each individual section, after a specifiedprescribed calculation, one sole characteristic value is formed.The latter is compared with an array of parametric data and as aresult of it one characteristic is isolated. Further on thischaracteristic is processed, memorized and serves for thegeneration of messages or information, respectively, depending onthis characteristic.6 claims, 3 figures

摘要： A stepped transformer has its winding switched to maintain a constant voltage at the secondary side by connecting parts of the primary together and with a winding part which can be energized in an opposite direction to the other winding parts on the primary side. An array of switches which are individually controllable serves to connect the winding of parts in combinations with each other for the voltage regulation.
