Abstract

The invention provides a special fitting for ground wire ice melting, and the fitting comprises: a drainage structure which has a conductive function and is connected with two wire clamp structures, wherein each wire clamp structure comprises a wire clamp body and a gland which are mutually hinged, the wire clamp body and the gland are provided with arc-shaped grooves which are correspondingly arranged, the arc-shaped grooves are formed in the wire clamp body, a cavity for placing an optical cable can be formed by the arc-shaped grooves of the wire clamp body and the arc-shaped grooves of thewire clamp body, a sheet conducting layer for coating the optical cable is arranged in the cavity, the sheet conducting layer and the wire clamp body are welded into a whole, and an elastic deformation layer for filling space is arranged between the sheet conducting layer and the inner wall of the cavity; and a locking structure which is used for fixing the relative positions of the gland and thewire clamp body.

Description

technical field [0001] The invention relates to the technical field of electrical fittings, in particular to a special fitting for melting ice from ground wires. Background technique [0002] Optical cable parallel fittings are used to melt ice for ground wires of overhead transmission lines. They have the advantages of strong flow capacity, light weight, portability, and flexible disassembly. Optical cable parallel fittings are used to break the connection between optical cables to form a closed loop. [0003] The traditional parallel wiring device for melting ice uses ordinary parallel trench clamps. The body and the gland are processed by profile cutting, and the bolts are prevented from loosening by using traditional spring washers. When the ice is melted and passed through a large current, it is easy to loosen due to the difference in thermal expansion coefficient of the material, thereby generating more heat. Ordinary parallel trench clamps have a small current flow c...
