Insulating sheath for connection point of overhead insulated conductor

Abstract

The invention provides an insulating sheath for a connection point of an overhead insulated conductor, and the insulating sheath employs a thermal contraction structure. The insulating sheath comprises an insulating protection layer which is made of an elastic insulating material, and wraps a conductor connection point. The insulating protection layer also comprises a thermochromic material whichchanges colors according to the temperature of the conductor connection point. The insulating sheath employs the thermal contraction structure, and is simple and easy in installation. The joint does not need to be sealed, and the insulating sheath can firmly wrap the insulated conductor. The insulating sheath is good in sealing performance, is good in age resistance, is long in service life, and wide in application range. Through the adding of the thermochromic material, the insulating sheath can reflect the temperature of the connection point of the overhead insulated conductor in real time,achieves the safety early warning effect, reduces the workload of line detection of a maintainer, and improves the work efficiency.

Description

technical field [0001] The invention relates to the field of electric equipment, in particular to an insulating sheath used for connection points of overhead insulated wires. Background technique [0002] With the in-depth transformation of urban and rural power grids, the original overhead bare wires are gradually replaced by insulated wires, which can reduce accidents due to external forces (conductive foreign objects such as branches, people and birds touching bare wires; motor vehicles touching poles, line cables etc.) lead to short circuit, grounding or insulator faults caused by blackout accidents, which will help reduce the accident rate and greatly improve the reliability of power supply; reduce the phase-to-phase distance between the wires in the line erection and the horizontal distance to the building, and reduce the risk caused by bare Unsafe factors caused by wires. After the line is insulated, the connection points of the wires (such as the lead wire connectio...
