Abstract

The invention discloses a pole-mounted transformer cable elbow-shaped head waterproof cover which comprises a waterproof cover shell, the waterproof cover shell comprises a transverse sleeve and a vertical sleeve which are integrally formed, the transverse sleeve is used for being arranged on the transverse part of a cable elbow-shaped head in a sleeving mode, and the vertical sleeve is used for being arranged on the vertical part of the cable elbow-shaped head in a sleeving mode. The waterproof cover is additionally arranged on the cable elbow-shaped head, so that the cable elbow-shaped headcan be effectively protected, the aging of the cable elbow-shaped head is delayed, and the problem of discharge of the cable elbow-shaped head due to damp is reduced in severe weather such as rain andsnow. A plurality of circles of rain skirts protruding outwards are arranged in the lower part of the outer wall of the vertical sleeve; the cable elbow-shaped head can be further protected, and water is prevented from entering the lower portion of the cable elbow-shaped head in rainy and snowy days. A tail end pipe hoop is arranged at an opening of the transverse sleeve and fastens the transverse sleeve to the wire end of the cable elbow-shaped head, and water is further prevented from entering the transverse sleeve.

Description

technical field [0001] The invention belongs to the technical field of waterproof appliances, and in particular relates to an elbow-shaped head waterproof cover for transformer cables on poles. Background technique [0002] The main reason for the accident of the outdoor power distribution 10kV elbow transformer is that the connection between the high-voltage flexible cable and the elbow is not tightly packaged and there are gaps in the manufacturing process, and moisture or moisture enters from the connection between the single-core cable and the conductor in rainy and snowy weather. Inside the cable core, under the action of the electric field, it discharges along the surface, and then causes a burning accident. [0003] The elbow-shaped head lacks protection, and it is prone to insulation tearing, aging and cracking of the outer insulation layer of silicone rubber under the action of outdoor ultraviolet radiation, natural external shaking, thermal effect of load current a...
