Abstract
Disclosed are an electrical penetration assembly, a manufacturing method thereof, and an electrical penetration device, which relate to the technical field of electrical penetration. The electrical penetration assembly comprises sealing glass (5), an outer tube (4) and a conductor (7) inserted into the outer tube (4), wherein both ends of the outer tube (4) are blocked by supporting and fixing blocks (8), and both ends of the conductor (7) respectively protrude from the corresponding supporting and fixing blocks (8); the sealing glass (5) is sintered between the conductor (7) and the outer tube (4) and is configured to divide an annular cavity jointly enclosed by the conductor (7), the outer tube (4) and the supporting and fixing blocks (8) into an upper cavity and a lower cavity; an optical fiber (14) penetrates the sealing glass (5), at least one end of the optical fiber (14) is connected to an optical fiber splice (3) after protruding from the corresponding supporting and fixing block (8), and a portion of the optical fiber (14) located in the sealing glass (5) is inscribed with a fiber Bragg grating to form a first fiber Bragg grating sensor (1). By utilizing the first fiber Br…
