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.

摘要翻译： 本发明涉及属于电力系统紧固件领域的自加压弹性垫圈，并且包括环形垫圈体。 通过利用中心轴作为对称轴将垫片体对称地折叠成V形，折叠边缘是加压位置，开口边缘是支撑位置。 垫圈主体的V形圆弧角α为140°-160°，圆弧半径R为10mm-30mm。 自加压弹性垫片由记忆合金制成，利用记忆合金记忆性能和超弹性特性的特点，有效地解决了普通的65Mn和60Si2MnA弹性垫片在下面的情况下可能失去弹性的问题 较高的温度，因此失去了防止固定件松动的效果，使得紧固件松动，接触不良导致接触阻力增加，从而使得加热更容易，从而使紧固件和紧固件燃烧，以及 从而导致电源故障。 自加压弹性垫片节省了定期更换所有紧固件所需的人力和物力资源，具有很好的经济和社会效益。
