Definitions

  • the invention relates to an on-load tap-changer head and an on-load tap-changer with an on-load tap-changer head.
  • the on-load tap-changer and the transformer are subject to the highest demands when used in electrical energy systems for reasons of supply security.
  • the transformers and on-load tap-changers are among the most financially complex parts of the system in this system.
  • the protection of these system parts is therefore a top priority and is prescribed in the standards.
  • the diverter switch oil tank is filled with a special insulating oil to cool and insulate the electrical lines. In the event of a fault, such as a breakdown due to the insulation effect of the insulation medium reduced by aging or moisture, there can be a sharp increase in temperature with a partial decomposition of the oil into gas and a sudden sudden increase in pressure.
  • Flow relays are used to detect an insulating oil flow from the interior of the on-load tap-changer out to the oil expansion tank caused by a pressure rise as a result of a fault.
  • a flow relay - also called a protective relay - is for example from the DE 1 952 048 A known.
  • the protection relay comprises a housing arranged outside the transformer, which is connected on the one hand to a pipe that comes out of the tap changer head, and on the other hand to a pipe that leads to the oil expansion tank.
  • a storage flap with a permanent magnet and a magnetically actuated reed switch are arranged inside the housing.
  • the lines of the reed switch are usually routed through ceramic bushings from the inside of the housing to the outside and above the housing.
  • the invention makes it possible to cleverly combine two components, namely an on-load tap-changer head and a detector device, for example in the form of a flow relay.
  • the flow flap By placing the flow flap in a separate area and the associated separation of the control room in a second area, the costs of the detector device are reduced enormously. Since the switches in the second area are no longer under oil, commercially available microswitches or the like can be used here. Costly implementation and switching elements that have to master the influences (corrosion, pressure, temperature) of the insulating oil are superfluous.
  • the transmission of the movements by means of the magnetic couplings is particularly durable and reliable.
  • the on-load tap-changer head can be designed in any manner, preferably as a flange cast from metal.
  • the first region can be formed in any manner, preferably by Pouring or milling into the on-load tap-changer head.
  • the flow flap can be designed in any manner and can preferably be mechanically connected to the first clutch magnet directly or via a first shaft.
  • the second clutch magnet in the second area can directly or indirectly actuate one or more switches. Furthermore, each position of the flow flap in the first area can be detected with a switch in the second area via a corresponding arrangement of the clutch magnets.
  • the second area can be designed in any manner and can be formed in the on-load tap-changer head or separately.
  • the second area can be formed above the first area outside the on-load tap-changer, next to and / or below the first area in the on-load tap-changer and / or outside of the on-load tap-changer in the tap changer and can consist of a separate housing.
  • the switches can be actuated in any manner, for example by a rotatable second shaft with cams for the respective switch.
  • the switches can be actuated directly or via a shaft by a preferably linear or radial movable second clutch magnet.
  • the switches can be closed or operated or opened or not operated in any position. For example, when the flow flap is folded over, a first clutch magnet can be removed from the immediate vicinity of the second clutch magnet and a switch can thus be opened or no longer actuated.
  • the switches can be designed in any way, for example as a microswitch, inert gas magnet switch, reed switch, flip switch, Hg toggle switch tube, proximity sensor or Hall sensor.
  • the flow flap has a recess or an aperture.
  • the size of the flow flap and the recess determine the flow rate at which the insulating fluid flips over the flow flap.
  • a reset device is mechanically connected to the second clutch magnet via the second shaft, and by actuating the reset device the first clutch magnet and thus the flow flap can be folded over from a second position into a first position by the second clutch magnet.
  • a reset is formed on the flow flap and the flow flap is actuated from a second position by actuating the reset a first position can be folded down.
  • the reset device is arranged in the first or second area and serves to directly or indirectly reset the flow flap from the first position to the second position.
