    摘要: A switching system for a step transformer having at least two adjacent taps and a pair of terminals shiftable between the taps has a pair of fixed contacts normally connected to the terminals, a vacuum interrupter connected between the terminals and displaceable between an open-circuit position and a closed-circuit position, a pair of movable contacts each engageable with a respective one of the fixed contacts and forming therewith a respective bypass switch, and a cam rotatable about a cam axis and having a contact face and an axially oppositely facing interrupter face each formed with a respective operating formation. A drive rotates the cam about its axis through steps of a half revolution. A respective cam follower engaged between each of the movable contacts and the contact-face formation opens and closes one of the bypass switches on rotation of the cam through a half revolution and thereafter opens and closes the other of the bypass switches on rotation of the cam through a succeeding half revolution. Another cam follower and a force storer engaged between the interrupter and the interrupter-face formation snap the interrupter open and then snap it closed each time the cam is rotated through a half revolution.

    摘要: The invention relates to an arrangement for automatically influencing a mains supply. A voltage transformer is provided as a pilot transformer which detects the real value of the voltage which is to be adjusted and which transmits said value to a motor drive via an individual electric measuring circuit in which means are provided for comparing said real value to a set point value and for producing an adjustment command which is dependent upon said comparison. The invention also relates to a correspondingly equipped motor drive provided with an additional control module which directly actuates an electric motor independently from the direction of rotation when required. Said electric motor drives a step-switching mechanism on the variable-voltage transformer, whereby the voltage is adjusted, thereby influencing the mains supply.

    摘要: A multiphase reactor-switching tap selector has a single geneva mechanism operating three shafts which traverse phase plates carrying all of the contacts and the vacuum switching cell and rapid release mechanism for each of the phases. The geneva mechanism operates the tap selection contacts directly through its shaft and is coupled to other shafts for operating the preseslector contacts, the bypass contacts and the vacuum switching cells. All three shafts traverse all of the phase plates.

    摘要: A motor-driven step switch for step transformers includes a drive motor connected to the step switch, display, input, and control units, a controller for actuating the drive unit in accordance with rotation direction, an information unit which obtains and transmits the step position and which is connected with the controller which delivers commands for controlling the drive motor and a switching operation, and an electrical connection between the controller and display, input, and control units. In accordance with this invention the information unit has a sensor for determining the absolute value of the actual position of the step switch, a nonvolatile memory unit for storing the position of the step switches with a range of step positions, and a unit for determining an end position of the step switch. It also has a programmable unit for storing specific data about the step switches to be actuated, an electronic unit for converting the stored data into serial form, and another electronic unit for controlling and monitoring the switching operation. The electrical connection with the controller and other display, input, and control units is formed by a single serial data line.
