Available in PDF, EPUB and Kindle. Book excerpt: Voltage breakdowns become a major concern in reducing the size of high-voltage power converter transformers. Even the smallest of voids can provide a path for corona discharge which can cause a dielectric breakdown leading to a transformer failure. A method of encapsulating small high voltage transformers has been developed. The method virtually eliminates voids in the impregnation material, provides an exceptional dielectric between windings and provides a mechanically rugged package. The encapsulation material is a CTBN modified mica filled epoxy. The method requires heat/vacuum to impregnate the coil and heat/pressure to cure the encapsulant. The transformer package utilizes a Diallyl Phthalate (DAP) contact assembly in which a coated core/coil assembly is mounted and soldered. This assembly is then loaded into an RTV mold and the encapsulation process begins.

Book Synopsis Improved Process for Impregnating High Voltage Transformers. Final Report by :
Download or read book Improved Process for Impregnating High Voltage Transformers. Final Report written by and published by . This book was released on 1976 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: High voltage transformers typically exhibit a 5 to 10% reject rate during corona and voltage breakdown tests because of incomplete impregnation. Sample coil assemblies were fabricated to provide data on the quality of four encapsulation processes: Bench Pour (pouring at atmospheric pressure and then deaerating), Vacuum Pour (placing units and material in a heated chamber and manually pouring under a vacuum) Vacuum-Pour-With-Positive-Pressure-Cure (same as Vacuum Pour except a positive pressure curing was used), and an Automated Encapsulation System (impregnating materials are stored in vacuum containers located in a heated chamber and then metered through static mixers). Results showed that an Automated Encapsulation System is equal to or better than the Vacuum Pour, Vacuum-Pour-With-Positive-Pressure-Cure, and Bench Pour processes.
