Contamination protection for high-voltage insulators

The device as claimed in one of the preceding claims,

• characterized in that
• at least one tab (40) has been attached in the attachment region (20) or on the protective screen (30).

The device as claimed in one of the preceding claims,

• characterized in that
• the protective screen (30) has been configured to be substantially circular, the radius of the protective screen (30) preferentially corresponding substantially to the outer radius of an arcing ring (6) of the high-voltage insulator (3).

The device as claimed in one of the preceding claims,

• characterized in that
• the protective screen (30) has been inclined toward the outside in such a manner that in the mounted state rainwater flows off outward, the inclination (α) preferentially amounting to 10° to 30°, more preferentially 20°.

The device as claimed in one of the preceding claims,

• characterized in that
• a drip edge (31) has been provided on the outer edge of the protective screen (30), and said drip edge (31) may take the form of a marginal element (31′) including a tab (40′″) extending across the mounting aperture (32).

The device as claimed in one of the preceding claims,

• characterized in that
• the attachment region (20), the protective screen (30) and/or the tab (40) are in one piece and/or made of synthetic material, preferentially of injection-moldable synthetic material.

An arrangement comprising a high-voltage insulator (3) with insulator cap (5) and a contamination-protection device (10) arranged on the insulator cap (5), wherein the contamination-protection device (10) has been designed as claimed in one of the preceding claims and has been connected to the insulator cap (5) by positive closure, wherein the insulator cap (5) is preferentially a clevis cap or a socket cap, and/or the high-voltage insulator (3) exhibits an arcing ring (6) in the region of the insulator cap (5).
