10kV overhead insulated conductors governed by a power distribution management institute are all aluminum core cross-linked insulated overhead conductors (the insulated overhead conductors are mainly JKLYJ-70mm 2-JKLYJ-240 mm 2), and the conventional connection of the overhead insulated conductors needs to be realized by stripping off conductor insulating layers and adopting a traditional parallel groove clamp or cross-connection winding mode.
The line breakage accident is more frequent (3 to 5 times per year) in the operation of 10kV insulated overhead line, 90 percent of line breakage faults are at the connecting position or the damaged position of a wire insulating layer, rainwater permeates into a seriously corroded wire core along the position of the insulating layer fracture, and deep analysis is carried out on each line breakage, which mainly comprises the following points:
(1) the insulation layer of the wire is damaged and not repaired, the insulation layer of the wire plays an insulation role and also bears corresponding tensile capacity, the wire is very easy to stretch particularly in hot summer under the action of force for a long time, and the cross section of the wire changes, so that a gap is generated on a contact surface to ignite, and the wire breakage is caused.
(2) And the connection is in a cross connection and winding type. The method has the advantages that the materials are convenient to obtain, but the defects of poor construction process and high construction technical difficulty are overcome, and some operation and maintenance personnel easily loose contact failure and cause ignition and wire breakage due to long-time operation because the wire cross-connection method is not skillful and the cross-connection key is not understood; because the connecting part is exposed in the open air for a long time, the joint is easily oxidized by exposure to the sun and rain, and the damaged insulating layer is not recovered.
(3) The traditional simple and convenient parallel groove clamp is adopted to connect the wires, although the construction is simple and convenient, the traditional parallel groove clamp can only be used as a connecting hardware fitting and does not have the function of splicing stressed hardware fittings, and the wire breakage fault is easily caused due to the incorrect use mode.
The occurrence of the disconnection condition directly threatens the healthy operation of equipment and the potential safety hazard of personnel electric shock particularly in urban area personnel intensive sections, and influences the stable operation of a power grid for preventing the occurrence of the disconnection and personnel electric shock events.
