AI Technical Summary
Existing high-voltage dry-type reactors are prone to problems such as decreased insulation performance, excessive partial discharge, and insulation failure under vibration and thermal cycling. Traditional structures cannot meet the stability requirements under high-voltage operating conditions under long-term vibration and thermal cycling.
Insulating support bars are installed between the insulating board and the iron core, and insulating varnish is poured in. Insulating elastic spacers are installed between the winding and the insulating board. Combined with the lower bearing platform, the upper bearing platform and the prestressed tensioning assembly, a rigid-flexible structure is formed. The insulating board, insulating support bars and the cured varnish layer form an interface bond constraint with each other. A vibration buffer layer is introduced to reduce the vibration coupling effect.
It improves the mechanical strength and deformation resistance of the reactor, reduces vibration transmission efficiency, reduces fatigue damage and insulation failure risk, and enhances the overall structural stability and insulation reliability.
