Abstract
A feed-through for feeding electric power to a submerged pump installed in a tank for cryogenic liquefied gases such as LNG and LPG. In the feed-through, a bushing made of an insulating material is inserted in the bushing insertion hole of a flange, and a conductor is inserted in the hollow part of the bushing. A gap between the flange and each end of the bushing insertion hole and a gap between each end of the bushing and the conductor are sealed airtight by seal members. A through-hole is formed in the wall of the bushing, and a space part communicating with the through-hole is formed in the flange. The pressure in the space part of the flange is detected by a pressure detector.
Claims7
A feed-through in which a bushing made from an insulating material is inserted into a bushing insertion hole in a flange, a conductor is inserted into a hollow portion of the bushing, and gaps between the flange and both ends of the bushing through-hole and gaps between both ends of the bushing and the conductor are each hermetically sealed, wherein:
- a through-hole passing through a wall section is formed on the bushing, and
- a space part communicating with the through-hole is formed on the flange.
A bushing that is made from an insulating material and is inserted into a bushing insertion hole in a flange of a feed-through, wherein a through-hole passing through a wall section is formed.
