Abstract

The present invention is a thermocouple penetrating piece used in the containing vessel of the reactor in the technical field of measuring processing variables in the nuclear engineering. In order to provide a thermocouple penetrating piece having simple structure, mature manufacturing process, low cost, reliable properties and good gas-sealing and pressure-bearing properties, the thermocouple penetrating piece used in the containing vessel of the reactor disclosed by the present invention comprises a pre-buried tube, a leakage detecting device, a connecting flange, a body of the penetrating piece and a thermocouple penetrating assembly connected to a thermocouple cable, the thermocouple penetrating assembly comprising a thermocouple connector integrally formed with the sealing connecting material and the mechanical socket, an armored thermocouple and its sealing tube and a transition tube welded with the sleeve of said armored thermocouple. The end plates in both ends of the body of the penetrating piece are welded with the transition tube of the thermocouple penetrating assembly to form a gas-sealing chamber which is connected to the leakage detecting device through a connecting pipe. The present invention has the higher pressure-bearing ability and the lower gas leaking rate, its producing process being mature, its properties being reliable and its manufacturing cost being low.

Description

Technical field [0001] The invention relates to an electrical penetrating piece of a pressure vessel, in particular to a thermocouple penetrating piece applied to the containment of a nuclear power plant reactor, which is used for realizing the penetration of the temperature measuring thermocouple's reactor containment and the lossless transmission of thermoelectric signals. Background technique [0002] Existing electrical penetrations for reactor containment in foreign countries, such as the French company AUXITROL, whose key technology is: the use of polyimide for electrical conductor insulation, and the use of polysulfone swaging and sealing techniques to achieve double sealing and insulation of conductor components ; The conductor assembly and the end plate are connected and sealed in a ferrule type, and are connected to an external cable through a terminal block or a wire lug. For the thermocouple penetration, the electrical conductor adopts the thermocouple wire material. ...
