Abstract
The present invention relates to an on-load tap changer device, which allows the automatic regulation of voltage in the secondary winding (28) of high-voltage electrical equipment (26, 65) by selecting the number of turns of the primary winding (27) by means of an on-load tap changer device (1, 40), having reduced volume and weight, obtaining the highest possible number of transformation ratios without changing the constructive arrangement of the high-voltage electrical equipment (26, 65).
Claims29
“Three-phase” on-load tap changer device comprising:
- at least one switching means per phase,
- at least one tap per phase,
- one selecting means per phase for selecting said at least one tap, provided with at least one electrical contact,
- one current-limiting element per phase,
- a first plate of insulating material,
- at least one protection element per phase,
- a second plate also of insulating material, and,
- an actuation element mounted between both plates, said actuation element being mechanically linked, as a single part, directly and simultaneously with the switching means and with the selecting means
- wherein the at least one switching means installed on the second plate and the taps installed on the first plate, the taps, the switching means and the selecting means thereby being mounted between both plates.
“Single-phase” tap changer device comprising:
- at least one switching means,
- at least one tap,
- at least one current-limiting element (18),
- a first plate of insulating material,
- at least one protection element,
- a second plate also of insulating material, and
- an actuation element mounted between both plates,
- wherein said actuation element in turn comprises at least one electrical contact,
- said actuation element (48) is mechanically linked, as a single part, directly with the switching means and electrically linked with at least one tap through at least one electrical contact, and
- the at least one switching means installed on the second plate and the taps installed on the first plate, the taps, the switching means and the actuation element thereby being mounted between both plates.
