Description
Дл зашиты линий св зи от пмдуктивного вли ни электрот говои сети электрифицирсванлых железных дорог однофазного тока примен ют отсасывающие трансформаторы , включенные в электрот говую сеть без обратного провода.For protection of communication lines from the inductance of the electric current of a network of electrified single-phase railways, suction transformers are used that are included in the electric network without a return wire.
Предлагаемый трансформатор более совершенен, по сравнению с известными трансформаторал и подобного рода, так как обеспечивает повынление защитного действи при синусоидальной форме тока в копта ктной сети.The proposed transformer is more perfect in comparison with the known transformers and of the similar kind, since it provides an increase in the protective action with a sinusoidal form of current in the Coptic network.
Дл этой цели предлагаетс первичную или вторичную обмотку трансформатора шунтировать ппдуктивным сопротивлением.For this purpose, the primary or secondary winding of the transformer is proposed to be shunted by means of a productive impedance.
При таком выполнении трансформатора он будет иметь комплексный коэффициент трансформации, который обеспечивает увеличение зашитного действи в 1,5 - 2 раза по сравнению с трансформатором, имеюнщм коэффициент тран:ч|)о;)мации , равный единице, даже при изменении переходного сопротивлени «рельсы-земл к весьма широких пределах.With this implementation of the transformer, it will have a complex transformation ratio, which provides an increase in protective action of 1.5 - 2 times compared to the transformer, which will have a ratio equal to one, even if the transition resistance of the rails changes - Land to very wide limits.
Кроме шунтировани обмоток трансформатора 1П1дуктн15Ны.м .Л ротивлением , комплексный коэффициент трансформации можно получить также путем изменени еоотношени числа витков обмоток трансформатора и,1и увеличени 1;оздуип-1ого зазора в магнитопроводе .In addition to shunting the windings of a 1P1 inductive transformer, the complex transformation ratio can also be obtained by varying the ratio of the number of turns of the transformer windings and, 1 and increasing 1;
Предмет и з о б р е т е н и Subject and title
Отеасывающнй трансформатор д.т зашиты линий слабого тока от индуктивного вли ни электрот говых сетей, о т л н ч а ю ш и и с тем. что, с целью повышени зашитного дейетви при сииусоидальной форме тока в контактной сети, первична или вторична обмотки трансОрорматора шунтироваиы индуктивным сопротивлением.The transformer transformer protects the weak current lines from the inductive influence of the electric networks, so that it is. that, in order to increase the protective action in case of a sius-shaped current in the contact network, the primary or secondary windings of the transformer are shunt induced by inductive resistance.
