Description

Предлагаемый линейный штыревой изол тор отнооитс  к известному типу изол торов, на головке которых помещаетс  первична  обмотка трансформатора тока, а вторична  размещаетс  внутри изол тора . Такие изол торы используютс  как трансформатор тока и конденсатор в схемах защиты линий высокого напр жени  при коротких замыкани х на землю.The proposed linear pin insulator refers to a known type of insulator, on the head of which the primary winding of the current transformer is placed, and the secondary is placed inside the insulator. Such insulators are used as a current transformer and capacitor in the protection of high voltage lines during short circuits to earth.

Особенностью изол тора-трансформатора тока, составл ющего предмет изобретени ,  вл етс  размещение сердечника из трансформаторной стали с вторичной обмоткой внутри удлиненной головки изол тора , чем обеспечиваетс  повышение коэффициента св зи между обмотками трансформатора.A feature of the current transformer isolator, which is the subject of the invention, is the placement of a core of transformer steel with secondary winding inside an elongated insulator head, thus increasing the coupling coefficient between the transformer windings.

Дл  использовани  предлагаемого изол тора-трансформатора тока дл  емкостного отбора мощности предусмотрена незамкнута  прокладка из фольги, помещенна  на вторичной обмотке и  вл юща с  одной из обкладок конденсатора, второй обкладкой которого служит первична  обмотка трансформатора тока.To use the proposed current transformer isolator for capacitive power take-off, an unclosed foil gasket is provided that is placed on the secondary winding and is one of the capacitor plates, the second plate of which is the primary winding of the current transformer.

На чертеже изображен предлагаемый линейный щтыревой изол тор-трансформатор тока, продольный разрез.The drawing shows the proposed linear pin-type current transformer, longitudinal section.

Первичной обмоткой 1 трансформатора тока служит провод пр моугольного сечени , навитый на головку 2 изол тора, а вторичной 3- катущка с сердечником 4, расположенна  внутри головюи 2 изол тора.The primary winding 1 of the current transformer is a rectangular wire wound on the insulator head 2, and the secondary 3-core with core 4, located inside the head and insulator 2.

Использу  емкость между первичной обмоткой / и незамкнутой обкладкой 5 из фольги, наложенной на вторичную обмотку, можно тот же изол тор попользовать дл  емкостного отбора мощности от линии электропередачи. Три таких трансформатора тока, соединенные в фильтр тока нулевой иоследовательности, и три конденсатора (на тех же изол торах), соединенные в фильтр напр жени  нулевой последовательности , дают возможность получить схему, реагирующую на все основные виды повреждений в сети-короткие замыкани  и замыкани  на землю.Using the capacitance between the primary winding / and the open foil lining 5 superimposed on the secondary winding, the same insulator can be used for capacitive power take-off from the power line. Three such current transformers, connected to a zero-sequence current filter, and three capacitors (on the same insulators), connected to a zero-sequence voltage filter, make it possible to obtain a circuit that reacts to all main types of network faults — short circuits and short circuits the earth.
