Moisture absorption device for electrical apparatus containing dielectric gas |
摘要 |
A molecular sieve moisture absorption device for electrical apparatus containing a dielectric gas includes a box in which the molecular sieve is placed. The box is closed by a plate provided with a valve through which the inside of the box is evacuated. The plate is held in place on a shoulder of the box by the action of pressure difference between the inside and the outside of the box after the inside of the box has been evacuated. A gasket is placed between the plate and the shoulder to ensure that the inside volume of the box is leakproof. The device can be stored independently of the apparatus. When the device is mounted on the apparatus, evacuating the case of the apparatus causes the plate to separate from the box, thereby putting the molecular sieve into contact with the inside volume to be treated of the case.
