Novel connecting and sealing structure for wire and pressure-resistant shell

The invention provides a novel connecting and sealing structure for a wire and a pressure-resistant shell, which is characterized in that the wire is led out from the pressure-resistant shell side of a condenser, the wire penetrates through a reserved flange cover and a lug (argon arc welding bottoming) with twelve holes in the inner ring and the outer ring, the lug serves as a thermal resistor penetration piece, and outlets of the lug are connected through hexagonal head bolts; wires of internal measuring points are led out through holes in the lug and the hexagon head bolt respectively, and after the lug and the hexagon head bolt are connected, resin adhesive is adopted as filler in an internal cavity to guarantee the air tightness of the internal cavity. According to the invention, the lead led out from the measuring point in the condenser passes through the pressure-resistant shell, so that the sealing performance of the pressure-resistant structure can be ensured under the condition of ensuring the norma
