Description

Предлагаемое -стройство предназначаетс  дл  сигнализации 1П)к однофазных замыкани х на землю в электрической установке с изолированной или комнененрованной нейтралью и с несколькими нрисоедине11 и  м и.The proposed device is intended to signal 1P) to single-phase earth faults in an electrical installation with an isolated or room neutral and with several connections.

Подобно известным устройствам Toio же целевого назначени  предлагаемое устройство основано на фиксации нанравлени  первой ПОЛУВОЛНЫ тока нулевой носледовательностн и содержит на выходе тиратроны н общее реле, включенные в анодные цепи этих тиратронов.Like the well-known Toio devices of the same purpose, the proposed device is based on fixing the current of the first HALF-WAY to zero current and contains at the output tiratrons and a common relay included in the anode circuits of these thyratrons.

Особенностью предлагаемого устройства, обеспечивающей повыщение селективности и ynpoHieiiHe конструкции,  вл етс  применение дл  определени  направ,лени  нолуволны тока Hy,ieBO i: последовательности магнитных элементов, вынолненных на тороидальных ферритовых сер дечниках с нр моугольной петлей гистерезиса. Магнитные элементы приключены по двоичпой схеме к общему трансформатору напр жени  нулевой последовательностн н к трансформаторам тока нулевой носледовательности каждого присоедине1Н1  н возде1 ств ют через каза1П1ые тиратроны на одно общее реле.A feature of the proposed device that enhances the selectivity and ynpoHieiiHe structure is the use to determine the direction, the generation of the current zero wave Hy, ieBO i: a sequence of magnetic elements mounted on toroidal ferrite cores with a rectangular hysteresis loop. The magnetic elements are coupled in a binary manner to a common zero voltage transformer sequentially to the current transformers of the zero continuity of each 1H1 connection and emitted via a single copper relay to one common relay.

На чертеже изображена принциниальпа  схема предлагаемо1 устройства.The drawing shows the principle of the circuit proposed 1 device.

Два тороидальных ферритовых сердечника (тора) Т получают одинаковый тактовый импульс от трансформатора напр женн  нулевой иоследовательностп ТННП. Оба тора предварительпо иамагпнчиваютс.: (при нажатии кпонки Л ). Один из них дает импульс на выходе при по ложнтельном значении напр жени  нулево пос,ледовате,1ьпоетн, др гоii - н)и отрицательном.Two toroidal ferrite cores (torus) T receive the same clock pulse from the transformer, the voltage zero and the sequence of the TNNP. Both tori are prefixed and compressed: (when pressing key L). One of them gives a pulse at the output, with a positive value of the voltage of zero-point, second, second, second, and negative.

К этому же трансформатору напр жени  нулево последовательности ТННП подключены пары торов Т, Т . . ., прпсоедпнеппые, кромтого , к соответствующим трансформаторам тока нулевой носледоватсм ; лости ТТИП. К выходу пар торов Т, Го ... подключены тиратроны У,. -11 ... с хо,тодным катодом. В обтзединенную це1н анодов тиратроноCouples of tori T, T are connected to the same voltage transformer of the zero-sequence TNNP. . ., for example, to the corresponding current transformers zero nosledovatsm; losti ttyp. To the output of pairs of tori T, Go ... are connected tiratrons U ,. -11 ... with ho, the cathode. In the open circuit of Tiratrono anodes
