Embodiment 1

[0018] The ceramic welded electrical penetration joint includes a metal conductor 4, which also includes a ceramic insulator 5, and a metal connecting flange 6, which separates the medium from the atmosphere, and the metal conductor 4 passes through the metal connecting flange 6, and the metal conductor 4 and the Metal connecting flange 6 runs through metal conductor 4 and ceramic insulator 5 is covered, and metal connecting flange 6 is equipped with a pressure monitoring device 8 on the atmospheric side.

[0019] The ceramic welding electrical penetration joint is installed between the power cable 1 on the medium side and the power cable 2 on the atmosphere side to separate the atmosphere from the medium, and can effectively prevent the medium from leaking to the atmosphere. The power cable 2 on the atmosphere side is connected to the connection box 3. The metal connection flange 5 is used to isolate the medium from the atmosphere in the ceramic welding electrical penetration ...

Embodiment 2

[0024] Double-layer ceramic welding electrical penetration joint, which includes ceramic welding electrical penetration joint I9, ceramic welding electrical penetration joint II10, one side of the ceramic welding electrical penetration joint I9 is ​​the medium end, and the other side is the pressure monitoring cavity. One side of the through joint II10 is an intermediate pressure monitoring cavity, and the other side is the atmosphere. The pressure monitoring cavity is a sealed space, and a pressure detection device is installed in the pressure monitoring cavity. The pressure monitoring chamber is filled with inert gas.

[0025] Such as image 3 As shown, the double-layer ceramic welding electrical penetration joint is improved on the basis of the ceramic welding electrical penetration joint, and the double-layer ceramic welding electrical penetration joint is used. The cavity formed between the ceramic welding electrical penetration joint I9 and the ceramic welding electrical...

Abstract

The invention relates to a packaging connector, in particular to an electrical penetrating packaging connector used in a low-temperature environment. An electrical penetrating connector for ceramic welding comprises a metal conductor and further comprises a ceramic insulator and a metal connecting flange, the metal connecting flange separates a medium side and an atmosphere side, the metal conductor penetrates through the metal connecting flange, and the metal conductor at the penetrating position of the metal conductor and the metal connecting flange is sleeved with the ceramic insulator. The low-temperature medium side is separated from the atmosphere side through welding sealing, electric power transmission is carried out well, and meanwhile the flammable and combustible media in a pump are prevented from leaking towards a connecting box along a cable. Meanwhile, a pressure monitor device arranged on the atmosphere side can discover the leakage situation through real-time detection. The sealing connector has the advantages of being simple in structure and safe and reliable in operation, and can meet the requirement of safe operation in a low-temperature work temperature. A ceramic-metal welding technology is adopted, the service life of a sealing boundary is long, and maintenance is avoided.

Description

technical field [0001] The invention relates to a packaging joint, in particular to an electrical penetration packaging joint used in a low-temperature environment. Background technique [0002] At present, such as LNG receiving station, LNG liquefaction plant, LNG carrier, floating LNG liquefaction storage device, coal coke oven gas methanation to produce LNG device, and the transportation of low-temperature media such as alkanes and olefins in chemical devices. Cryogenic submersible pumps are required for the transportation, loading and unloading of low-temperature media, because low-temperature media such as LNG, alkanes, and olefins have the characteristics of low temperature, flammability, explosion and vaporization. Therefore, the working conditions of the pumps conveying this medium are harsh, and the requirements for materials, sealing and other aspects are very strict, and the equipment is required to have safe and reliable sealing. Due to the difficulty in design,...
