Recently , The composite shell capacitor bushing by Nanjing Electric R&D independently has pass the national technology appraisal, and the main technology performance of products come to the international high-level in like products.
On 13&14 Sep,2014, Authorized by the national energy administration, China machinery industry federation hosted new product technology assessments meeting of the 550 KV composite shell capacitive bushing by Nanjing Electric R&D in Nanjing, Three gorges office of the state council, national energy administration, ministry of industry, to attend, from the west on the court, its electricity institute, its dc, south net electric institute, China electric institute, xi an jiaotong university, shen yuan, tianwei change, change especially electrician scale and other units of 15 experts appraisal committee.
Appraisal committee heard the development summary report, examine the identification information, give product sampling inspection. Appraisal suggestions after serious discussion as follows: submit identification of technical documents complete, correct, unified, conform to the requirements of the technical appraisal, can guide production. Products are test by the electric power industry electrical equipment and instrumentation quality inspection and test center, the test results accord with GB/T 4109-4109, IEC 60137:2003 and the provisions of the relevant technical specifications; By the state key laboratory of Tongji University civil engineering disaster prevention earthquake shaking table laboratory tests (0.4 g acceleration level, vertical acceleration of 0.26 g). Field sampling test results qualified; The air side for composite coat, the overall electrical and mechanical structure design is reasonable, electric performance is good, strong ability to resist earthquake; The company with complete production equipment, advanced process equipment, detection means complete, has passed the "three standard" management system certification, satisfies the requirement of mass production. Appraisal committee said: the product comprehensive technical performance reached the international advanced level of similar products, agreed to by the product technical appraisal, can batch production.According to information, 550KV composite shell capacitor bushing is made for Baoding Tianwei Baobian Electric Co.,ltd 550KV transformer by us. The bushing will be used in the southern power grid in Yunnan Jinsha river middle reaches station sending Guangxi HVDC project gold officer converter transformer station network measurement. Yunnan is a quake-prone region, which put forward higher requirements on the seismic resistance of electric power equipment including transformer bushing. The outer insulation of transformer bushing air end adopts hollow composite insulator, strong seismic performance, to meet the safe operation of the requirements of earthquakes and earthquake area, known as "anti-seismic" bushing.
To meet the needs of the national electric power construction, and improve the bushings series, since this year, Nanjing Electric actively organize technical personnel, relying on the long-term accumulation in enterprise in the research and development production of casing, insisting on independent innovation, R&D the 550 kv capacitive transformer bushing composite coat, and successfully conquer the bushing’s key technology, make the casing can satisfy products in electrical, bending, anti-seismic, sealing performance etc. In April 2014, complete prototyping and factory test, in May, 2014 complete product type test,, in June 2014 pass the seismic test.Copyright © 2015 All rights reserved by Nanjing Electric HV Bushing Co.,Ltd.
