ENCAPSULATED FUSE WITH CORONA SHIELD

摘要

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).
