Description

Игобретеиие относитс  к герметизированным маслорасширител м дл  маслонаполненных высоковольтных электрическнх аппаратов, например дл  трансформаторов тока высокого напр жени .The invention relates to pressurized oil expanders for oil-filled high-voltage electrical equipment, for example for high voltage current transformers.

Известные маслорасшнрители такого рода, также работающие при посто нном объеме и сообщающиес  с анпаратом через отверстие в нижней части корпуса последнего, не обеспечивают возможности отсоединени  маслорасщирител  от аппарата, что затрудн ет транспортировку их и усложн ет ревизию н ремонт аппарата.Known oil diffusers of this kind, also operating at a constant volume and communicating with the device through the opening in the lower part of the body of the latter, do not provide the possibility of disconnecting the oil expander from the apparatus, which complicates their transportation and complicates the revision and repair of the apparatus.

Дл  устранени  указанных недостатков предлагаетс  маслорасщиритель выполн ть в виде отдельного бака, соединенного с аппаратом трубкой.To eliminate these drawbacks, it is proposed that the oil expander be made as a separate tank connected to the apparatus with a tube.

Предлагаемый маслорасщиритель совместно с высоковольтным трансформатором тока представлены на чертеже.The proposed lubricator together with a high-voltage current transformer is shown in the drawing.

Маслорасщиритель I представл ет собой тонкостенный сварной бак, закрытый герметически и расположенный отдельно от трансформатора тока 2. Нижн   часть бака соедин етс  с нижней частью корпуса трансформатора посредством металлической трубки 3 с краном 4. Кожух 5 предохран ет кран от поврежденийУровень масла контролируетс  по маслоуказателю 6.The oil remover I is a thin-walled welded tank, hermetically sealed and located separately from the current transformer 2. The lower part of the tank is connected to the lower part of the transformer housing by means of a metal tube 3 with a tap 4. The hood 5 protects the tap from damage. The oil level is monitored by oil indicator 6.

Маслорасщиритель работает по принципу воздушного колокола. Корпус трансформатора заполн ют маслом при открытом кране. Бак маслорасщирител  при этом заполн етс  маслом так, что давление газа в баке уравновещиваетс  гидростатнчееким напором масла в трапсформаторе .The oil conditioner works on the principle of an air bell. The transformer housing is filled with oil when the faucet is open. At the same time, the oil diluent tank is filled with oil so that the gas pressure in the tank is balanced by the hydrostatic pressure of the oil in the trapsformator.

Дл  сушки и пропитки трансформатора кран закрываетс , после чего в трансформатор может быть подан вакуум. По окончании пропитки вакуум снимаетс , открываетс  кран и если нужно в трансформатор доливаетс  масло. Кран закрываетс  герметическим кожухом.For drying and impregnating the transformer, the tap is closed, after which a vacuum can be applied to the transformer. At the end of the impregnation, the vacuum is removed, the valve opens and, if necessary, oil is added to the transformer. The valve is sealed with a hermetic enclosure.
