Ct energy extraction device

A CT energy extraction device, comprising:

• a first housing and a second housing, wherein a first accommodation cavity is provided in the first housing, a second accommodation cavity is provided in the second housing, and the first housing can be connected and joined with the second housing to form a ring shape, which is used to be placed on outside of a high-voltage line;
• a first iron core disposed in the first accommodation cavity, wherein an energy- extraction coil is wound around the first iron core, a cable outlet is provided on the first housing, and the energy-extraction coil has pins extending from the cable outlet;
• a second iron core disposed in the second accommodation cavity, wherein when the first housing and the second housing are connected and joined, the first iron core and the second iron core are joined to form a closed ring structure;
• wherein an inflating assembly is provided on the first housing and/or the second housing, the inflating assembly comprises an inflating nozzle, an air bag, and a cover, the inflating nozzle is connected to the air bag and is used to inflate the air bag, the cover is used to block the inflating nozzle after inflation is completed;
• wherein after the air bag is inflated, the air bag is able to squeeze the first iron core and/or the second iron core, so as to reduce an air gap between joint surfaces of the first iron core and the second iron core.
