Abstract: An encapsulated fuse (10) for power distribution systems and method for producing such fuses is provided. A fuse includes a body (20) with opposing terminals (30, 40). A corona shield (50) is generally coaxial with the fuse (10) and substantially extends the full length of the fuse body (20). The corona shield (50) is electrically coupled at its first end (70) with a first fuse terminal (30). The second end (80) of the corona shield (50) has a slightly larger cross-section than the first end (70) to provide electrical isolation from the second fuse terminal (40). The fuse (10) and attached corona shield (50) are molded in an encapsulating material (150).

Abstract: A shielded encapsulated vacuum interrupter with a ceramic vacuum chamber and opposing conductive end caps is provided. One end cap is electrically connected to a fixed contact, while an opposing end cap is connected to a moving contact. The moving contact is actuatable with the fixed contact for opening or closing an electric circuit. A floating shield inside the vacuum chamber connected to the vacuum chamber ceramic wall and spaced from the fixed and moving contacts is isolated and has a floating voltage potential. A portion of the vacuum chamber exterior ceramic wall is coated with a semi-conductive material and conductive voltage screens enclose a portion of the vacuum chamber exterior and are electrically connected to each conductive end cap of the vacuum chamber. The chamber and connected screens are encapsulated in a molded dielectric housing.
