Definitions

  • the invention relates to an on-load tap according to the reactor switching principle for uninterrupted load switching between different winding taps of a tapped transformer.
  • a control transformer with a tap changer is known.
  • the transformer has a main winding and a control winding for each phase.
  • each phase is associated with a throttle (preventive autotransformer), which is used as a switch-over reactance of the, separately arranged outside the control transformer, tap changer during the switching operations.
  • the three over-reactances of the three phases are arranged on the upper yoke of the trunk and control windings.
  • throttles Since the throttles are arranged directly on the yoke, they must be particularly well insulated in the arrangement of the tap changer on the high voltage side, ie the high voltage potential, compared to the on the ground potential transformer yoke. This has a strong effect on the manufacturing costs of such chokes.
  • the wiring of the chokes with the respective tap changers is complex and must also be isolated very well against the ground potential.
  • the object of the invention is to provide an on-load tap according to the reactor switching principle, with the help of the chokes produce cheap, simple and easy to wire with the on-load tap-changer.
  • This object is achieved with an on-load tap changer according to claim 1.
  • the features of the subclaims form advantageous developments of the invention.
  • the invention proposes an on-load tap changer according to the reactor switching principle for the uninterrupted load switching between different winding taps of a tapped transformer, comprising:
  • the throttle is a component of the on-load tap-changer or integrated in the on-load tap-changer.
  • the choke which may be, for example, a coil or inductance
  • the choke must be insulated less, ie with fewer layers of insulating paper on the windings, from the earth potential. This simplifies the production of the throttles and the Costs reduced.
  • the connection in particular the wiring of the throttle with the on-load tap-changer is less expensive, since the distance between the two parts is shortened to each other.
  • the throttle may be formed in any manner, for example comprising one, two or three windings, which are secured to the adapted iron core with a yoke.
  • the on-load tap changer can be configured as desired in any desired manner and, for example, comprise at least one additional or additional throttle and / or be designed for single-phase, two-phase or three-phase applications. If there is more than one phase, at least one throttle is provided for each phase.
  • the on-load tap-changer is designed as a load selector.
  • the load selector can be designed in any desired manner and include, for example, vacuum interrupters or simple switching contacts in oil for switching under load.
  • the throttle is disposed at an upper end or at a lower end of the load selector.
  • the arranging can be carried out in any desired manner, for example via holders or over the iron core of the throttle.
  • the on-load tap-changer is designed as a combination of diverter switch and selector.
  • the diverter switch can be designed in any desired manner and can include, for example, vacuum interrupters or simple switch contacts.
  • the selector can be designed in any desired manner, for example with or without a preselector and / or as a linear selector or rotary selector.
  • the throttle is arranged at the upper end or at a lower end of the diverter switch and / or
  • the throttle arranged at the upper end or at a lower end of the selector is.
  • the arranging can be carried out in any desired manner, for example via holders or the iron core of the throttle.
  • the diverter switch and the selector are connected via an iron core of the throttle and
  • the throttle is arranged on the iron core between the diverter switch and selector.
  • the on-load tap changer is or can be arranged on an upper part of a transformer housing.
  • the on-load tap-changer is or can be arranged on an insulating foot on a lower part of a transformer housing.
  • the Isolierfuß can be performed in any manner, for example as a cylinder, scaffolding or block, and / or be made of fiberglass, kraft paper cylinder and / or wood.
  • the on-load tap-changer and the choke are wired in such a way that both have the same voltage potential to the ground potential.
  • the on-load tap-changer is or may be used in a tapped transformer.
