Abstract
Description
Technical Field
[0001] The present application relates to the field of polymer materials and electrical insulation technology, and in particular to an electric high-voltage resistant self-repairing polyimide insulation sheath. Background Art
[0002] Polyimide insulation sheaths, a crucial component of insulation protection for power equipment, are widely used in high-voltage cable joints, transformer bushings, and switchgear. Their high-voltage resistance and self-healing capabilities are crucial for ensuring the safe operation of power systems. As power equipment evolves toward highly integrated and complex operating environments, insulation sheaths must simultaneously meet complex functional requirements such as stable clamping, adaptive adjustment, and long-lasting insulation under dynamic mechanical stress, irregular spatial installation, and compatibility with multiple equipment specifications. This poses new challenges to the sheath's structural design and material properties.
[0003] However, the current insulating sheath technology has some shortcomings: traditional supporting structures mostly adopt a fixed design, lacking the ability to dynamically adjust the angle and height. When installed at an angle or the base surface of the equipment is uneven, it is easy for the sheath to not fit tightly with the equipment interface. During long-term operation, it may cause displacement due to mechanical vibration, affecting the stability of protection; conventional clamping mechanisms rely on preset specifications to match, which is difficult to adapt to the contours of variable-diameter components or special-shaped equipment, and can easily cause local clamping force overload or contact failure, which not only reduces the clamping reliability, but may also accelerate the wear of the sheath structure; the existing insulating material system is single, and is prone to irreversible damage under the synergistic action of high-voltage electric fields and mechanical stress, and lacks a self-repair mechanism, resulting in the gradual degradation of insulation performance over the use cycle.
