In order to promote the trial operation of 10KV open dry transformer and improve the reliability of dry transformer, the state grid department organized a seminar on the technical specifications of 10KV open dry transformer in Beijing on April 19.State grid Beijing, Tianjin, Shandong, Shanghai, Jiangsu, Zhejiang, Anhui, Fujian electric power, Nanrui group Shanghai zhenxin electric co. LTD. Shandong electric, China electric power research institute, state grid economic research institute, dupont China group co, LTD.The meeting heard dupont company on dupont NOMEX insulation system based on the open three-dimensional coil core dry distribution transformer technology advantages report that reviewed the 10KV open dry transformer technical specifications, identified the pilot unit, and the follow-up work deployment, summary is as follows:
1, the open-type solid coil dry-type distribution transformer based on dupont NOMEX insulation system is convenient in insulation performance, no-load loss, noise level, etc and has obvious technical advantages over the traditional dry-type transformer with epoxy resin insulation and laminated core structure.
2, Before May 10, China institute of electric power technology will lead the efforts to organize experts to improve the technical specifications and dry change material sequence and put them into the demonstration catalogue according to the revision opinions put forward at the meeting.
Three, the meeting identified the state grid Beijing, tianjin, shandong, Shanghai, jiangsu, zhejiang, anhui, fujian electric power open-type three-dimensional coil dry type distribution transformer pilot units.Before July 30, the number of each pilot unit will be no less than 100.After each pilot unit feedbacks the application situation next year, further clarifies the promotion application related guidance.
