Abstract
В отделни случаи при превключване на предизбирач на стъпален регулатор се налага да се използват полюсни резистори (4). Най-често те се монтират в изолационен цилиндър (3) и се разполагат под избирача (1). В повечето случаи полюсните резистори са включени постоянно, поради което техният брой нараства значително. Натоварването на полюсните резистори и техният брой чувствително се намаляват, ако те работят само по време на превключването на предизбирача. За целта се използва устройство за кратковременно включване, което е обособено в отделен възел (5) и е разположено под долната плоча (6) на предизбирача. По този начин конструкциите и габаритните размери на избирача (1), предизбирача (2) и възела на полюсните резистори (4) не се променят. Предлагат се два варианта на механизма на устройството. При първия се използва двупозиционна малтийска предавка (18-21), комбинирана с ускоряваща зъбна предавка (15-16). На вала (20) на малтийския сектор (21) е хваната трилъчева звезда (22), към коятоса монтирани контактни пластини (23) на подвижна контактна система. Неподвижните контактни елементи (8) са установени на изолационния цилиндър (3) и два изолатора (25) свързани с горната носеща планка(13). При завъртане на подвижната система (9) на предизбирача (2) механизмът осигурява контактуване с първата стъпка на малтийската предавка и отваряне при втората стъпка. При втория вариант на механизма се използва съчетание на ускоряващата зъбна предавка (15-16) с гърбичеIn individual cases, pole resistors (4) must be used when switching to a step switch. Most often, they are mounted in an insulating cylinder (3) and placed under the selector (1). In most cases, pole resistors are permanently switched on, so their number increases considerably. The load of the pole resistors and their number is considerably reduced if they work only during the preselector switching. For this purpose, a short-time switching device is provided which is disposed in a separate node (5) and is located below the lower plate (6) of the preselector. In this way, the structures and dimensions of the selector (1), preselector (2) and node of the pole resistors (4) do not change. Two versions of the device mechanism are available. The first one uses a two-position Maltese gear (18-21) combined with an accelerated toothed gear (15-16). On the shaft (20) of the Maltese sector (21) a triangular star (22) is housed, to which contact plates (23) of a movable contact system are mounted. The immovable contact elements (8) are located on the insulating cylinder (3) and two insulators (25) connected to the upper bearing plate (13). When the movable system (9) of the preselector (2) is rotated, the mechanism provides contact with the first step of the Maltese gear and opening in the second step. In the second embodiment of the mechanism a combination of the accelerating gear (15-16) with a cam
