Description

Дл защиты изол ции электрических двигателей, работающих в воде , их устанавливают в водоиепроницаемые кожухи, заполн емые изо-лирующей жидкостью (например маслом), наход щейс под давлением.To protect the insulation of electric motors operating in water, they are installed in water-permeable housings filled with insulating fluid (for example, oil) under pressure.

Предлагаемый способ по Сравнению с известными более соверщенен , так как позвол ет повысить давление, под которым находитс изолирующа жидкость.The proposed method is more perfect in comparison with the known ones, since it allows to increase the pressure under which the insulating liquid is located.

Это достигаетс тем, что кожух двигател заполн ют жидкостью, имеющей удельный вес больщий, чем удельный вес воды.This is achieved by filling the engine cover with a fluid having a specific gravity greater than that of water.

Дл осуществлени предлагаемого способа над кожухом двигател может быть установлен запасной бак (консерватор), который сообщаетс трубкой с кожухом двигател . Верхн часть этого бака закрываетс порщн.ем или свободно сообщаетс с водой через фильтр.In order to carry out the proposed method, a spare tank (a conservator) can be installed above the engine casing, which is connected by a pipe with the engine casing. The upper part of this tank is covered with a liquid or freely communicated with water through a filter.

С целью уменьщени содержани воды в изолирующей жидкости, лубрикатор заполн ют жидкостью, удельный вес которой больще удельного веса воды и меньще удельного веса жидкости, заполн ющей кожух двигател .In order to reduce the water content of the insulating liquid, the lubricator is filled with a liquid whose specific gravity is greater than the specific gravity of water and less than the specific gravity of the liquid filling the engine cover.

Предмет изобретени Subject invention

Claims

1. A method of protecting an electric motor operating in water from water by filling the waterproof casing of the engine with insulating fluid under increased pressure, characterized in that, in order to realize the increased pressure, a liquid having an individual weight of more than than the specific gravity of water.

2. Acceptance of the implementation of the method according to claim 1; and in order to reduce the water content of the insulating liquid, the soil taper is filled with a liquid, the specific weight of which is more than specific No. 113958-2 -

the weight of the water and the less-than-average weight of the fluid that fills the engine so that it prevents direct contact of the latter with water.

3. For carrying out the method according to claims. 1 and 2 is the use of a spare tank (conservator) located above the engine casing, connected by a tube to KostytffOM and in its upper part closed with a tank or freely through a filter that communicates with water.
