Abstract

The invention discloses a method for connecting a dry-type high-voltage bushing capacitor core and a flange. The method comprises the following steps: 1, turning a connecting thread on the inner wall of the flange; 2, turning a connecting thread on the outer wall of the dry-type capacitor core; 3, placing an O-shaped sealing ring and a buffering cushion in a sealing groove of the flange; 4, coating the connecting threads of the dry-type capacitor core with epoxy glue; 5, screwing the dry-type capacitor core on the flange through a tool; and 6, installing other parts such as an insulation sleeve to form the dry-type high-voltage bushing. The insulating sleeve in the sixth step comprises a ceramic sleeve and connecting flanges arranged at the two ends of the ceramic sleeve. The bushing is convenient and reliable to install, the assembling efficiency is remarkably improved, meanwhile, the mechanical strength of the flange part of the sleeve can be obviously improved, and then the mechanical performance of the bushing is improved.

Description

technical field [0001] The invention relates to a connection method between a capacitor core and a flange of a dry-type high-voltage bushing, belonging to the electrical field. Background technique [0002] The capacitive core and the flange of the conventional transformer bushing are fixed by a glued structure or a clamping structure. The glued strength of the glued structure fixed bushing mainly depends on the mechanical strength of the glued epoxy resin. There is a risk of stress concentration and long-term vibration loosening. Contents of the invention [0003] In order to solve the deficiencies of the prior art, the present invention provides a method for connecting the capacitor core and the flange of the dry-type high-voltage bushing, which is convenient and reliable to install, and can significantly increase the flange position of the bushing while significantly improving the assembly efficiency. Mechanical strength, which in turn improves the mechanical propertie...
