摘要:
The present invention relates to a self-pressurized resilient gasket, which belongs to the field of electric power system fasteners, and comprises an annular gasket body. The gasket body is symmetrically folded into a V-shape by utilizing the central axis as an axis of symmetry, the folded edges are the pressurization position and the open edges are the supporting position. The V-shaped circular arc angle α of the gasket body is 140°-160°, and the radius R of the circular arc is 10 mm-30 mm. The self-pressurized resilient gasket is made of a memory alloy, and utilizes the characteristics of the memory alloy—memory performance and superelasticity characteristic to effectively solve the problems that common 65 Mn and 60 Si2MnA spring gaskets may lose elasticity in case of being under a higher temperature frequently, thus losing the effect of preventing a fastened piece from being loosened, so that the fastened piece is loosened and contact resistance is increased due to poor contact, thus causing heating more easily, which burns the fastener and the fastened piece, and thereby causing faulted power failure. The self-pressurized resilient gasket saves a number of manpower and material resources required by regularly replacing all the fasteners, and has very good economic and social benefits.
