Electrified railways cast resin dry-type transformers

Vacuum casting resin insulation dry-type transformers are using new insulating materials and advanced technology production of a new transformer, because of its high adaptation filthy, hot, humid environment, flame retardant, fire, pollution, etc., are called energy type,  electric meter  protection, disaster prevention transformer, widely used at home and abroad. In order to develop suitable for China 275kV  electri cenergy meter  railways cast resin dry-type transformers. Through analysis that electrified railway transformer 275kV most characteristic and representative of traction substation, partitioning kiosks and other premises used for transformer, so make sure to start from the transformer research to develop a relevant  air circuit breaker  and technical specifications. 1999 completed three single-phase prototype design, manufacturing and various tests. Respectively, in Longhai line Yaocun partition kiosks and traction substation east of Xi'an, Baoji-Chengdu line Swallow acupuncture traction substation put into trial operation, normal operating conditions are safe.
