Abstract

A találmány tárgya indukciósan szabályozottfeszültségszabályozó, különösen ilyen indukciósan szabályozottvillamos transzformátor vagy reaktanciatekercs. Ez afeszültségszabályozó transzformátor, vasmagon alapuló mágneskörttartalmaz, amelyben legalább egy fluxusút vagy oszlop (2) van, amelyetnagyfeszültségű tekercs (3) és kisfeszültségű tekercs vesz körül. Atalálmány tárgya továbbá a feszültségszabályozóban alkalmazottszabályozó tekercs, valamint eljárás feszültség szabályozására. Azoszlop (2) legalább két oszlopágra (2A, 2B) van osztva. Ezek közüllegalább az egyik oszlopág (2B) szabályozó elrendezést tartalmaz,amelyben változtatható permeabilitású zóna van. A permeabilitást alégrésként kialakított zónába befelé és abból kifelé mozgathatómágneses rúddal (4) lehet változtatni. Egy másik kiviteli alakban aváltoztatáshoz szabályozó tekercset használunk, amely a oszlopágon(2B) átmenő mágneses fluxusra hat. A változtatható permeabilitásúzónát tartalmazó oszlopág (2B) köré kompenzáló tekercset lehethelyezni. A kompenzáló tekercs (7) villamosan kondenzátorral van sorbakötve. Legalább az egyik tekercs villamos vezetőből, belső félvezetőelső rétegből, szigetelő rétegből és külső félvezető második rétegbőlálló nagyfeszültségű kábelből van tekercselve. Ó The subject of the invention is an inductively regulated voltage regulator, in particular such an inductively regulated current transformer or reactance coil. This voltage regulating transformer consists of a magnetic circuit based on an iron core with at least one flux path or column (2) surrounded by a high voltage winding (3) and a low voltage winding. The subject of the invention is also the regulating coil used in the voltage regulator, as well as a method for voltage regulation. Azo column (2) is divided into at least two column branches (2A, 2B). Among them, at least one of the column branches (2B) contains a control arrangement in which there is a variable permeability zone. The permeability can be changed with a magnetic rod (4) that can be moved in and out of the zone formed as a sub-air gap. In another embodiment, a control coil is used for the change, which acts on the magnetic flux passing through the column branch (2B). A compensating coil can be placed around the column branch (2B) containing the variable permeability zone. The compensating coil (7) is electrically connected in series with a capacitor. At least one of the coils is wound with a high-voltage cable consisting of an electrical conductor, an inner semiconductor first layer, an insulating layer, and an outer semiconductor second layer.
