Line outgoing casing pipe applied to high-pressure superconductivity electrical equipment

Abstract

The invention discloses a line outgoing casing pipe applied to high-pressure superconductivity electrical equipment. The line outgoing casing pipe is composed of a fiber reinforce plastic protective cover (1), low-temperature glue soaking paper (2), a lead (3) and an umbrella skirt (4). A clamping mechanism composed of a clamp nut (5) and a sealing gasket (6) is arranged on a low-temperature container cover board. The upper ends of the fiber reinforce plastic protective cover (1), the low-temperature glue soaking paper (2) and the lead (3) are located in the room-temperature environment, and the lower ends of the fiber reinforce plastic protective cover (1), the low-temperature glue soaking paper (2) and the lead (3) are inserted into a low-temperature container. The umbrella skirt (4) is arranged on the upper portion of the fiber reinforce plastic protective cover (1) so as to reduce creepage along the surface of the low-temperature container upper cover board by the lead (1). The fiber reinforce plastic protective cover (1) and the umbrella skirt (4) are formed by machining fiber reinforce plastic bars, the glue soaking paper (2) is made of Nomex paper or PPLP or polyimide glass wool cloth composite paper with low-temperature glue or paint by utilizing the vacuum pressure encapsulation technology or the vacuum pressure impregnation technology, wherein the Nomex paper or the PPLP or the polyimide glass wool cloth composite paper is resistant to low temperature, high in pressure-resistant strength and easy to impregnate.

Description

technical field [0001] The invention relates to an outlet bushing of high-voltage superconducting power equipment. Background technique [0002] In recent years, great progress has been made in the research and development of high-voltage superconducting power equipment, and superconducting power equipment such as superconducting transformers, superconducting reactors, and superconducting current limiters have entered the demonstration operation stage. Different from strong-field superconducting devices used in scientific instruments and medical equipment, superconducting power equipment faces problems such as overvoltage and overcurrent shocks, and it is difficult to use liquid helium cooling or conduction cooling of refrigerators. Superconducting power equipment mostly operates in the liquid nitrogen temperature zone. Generally, superconducting coils are assembled in cryogenic containers with good thermal insulation performance, and liquid nitrogen evaporative cooling or f...
