Description
довательно, не подвергаетс окислению. Так как при этом рабочие поверхности подвижного электрода 3 тоже не соприкасаютс с воздухом, то и они защищены от окислени . Это создает стабильный и надежный контакт с лентами 2. Дл лучщего облегани верхней поверхности подвижного электрода 3 верхним слоем ленты 2 подвижный электрод снабжен роликами 4, прижимаемыми к верхнему слою ленты 2 пружиной 5. Нижние слои ленты 2 креп тс к изол ционному основанию 6. Если основание 6 выполнить из дерева, то крепление нижнего сло ленты можно осуществить гвозд ми . Верхний слой ленты 2 крепитс к осноианию 6 лишь в своих оконечност х.consequently, it does not undergo oxidation. Since the working surfaces of the movable electrode 3 are also not in contact with air, they are also protected from oxidation. This creates a stable and reliable contact with the strips 2. For better fitting of the upper surface of the movable electrode 3 with the upper layer of the tape 2, the movable electrode is provided with rollers 4 pressed against the upper layer of the tape 2 by a spring 5. The lower layers of the tape 2 are attached to the insulating base 6. If the base 6 is made of wood, then the fastening of the lower layer of the tape can be done with nails. The upper layer of the tape 2 is fixed to the base 6 only in its extremities.
Перемеща но лентам 2 подвижный электрод 3, можно мен ть величину сопротавлени , включенного в цепь.By shifting the strips 2 of the movable electrode 3, it is possible to vary the amount of resistance included in the circuit.
Преимущество предложенного устройства в том, что не требуетс герметизаци как от утечки жидкого металла, так и дл предохранени от окислени контактируемых поверхностей электродов. Окисление верхнего сло ленты не играет существенного значени дл работы устройства. Реостат удобен и прост как при регулировании тока в цени, так и при производстве ремонта. Устройство устойчиво к пинчам и не подвержено влению плавани контакта.The advantage of the proposed device is that it does not require sealing against leakage of liquid metal, and to prevent oxidized contact surfaces of the electrodes. Oxidation of the upper layer of the tape does not play a significant role in the operation of the device. The rheostat is convenient and simple both in current regulation in price and in the manufacture of repairs. The device is resistant to pinch and is not subject to swimming contact.
