China's first Chuxiong ± 800kV HVDC Transmission Project converter station located in the state Chuxiong Lufeng, this project under the China Southern Power Grid peace EHV Bureau.

    ± 800kV Yun Guang HVDC transmission project in China and even the world's first HVDC transmission project, which is the China Southern Power Grid "Eleventh Five-Year" from west to east an important part of the main grid. The project not only to meet in Small Bay, and other large hydropower Jin'anqiao sent and the "Eleventh Five-Year" goes to send the Guangdong electricity needs, the promotion of energy resources in the optimal allocation within a larger, more importantly, will contribute to China's power industry design, manufacturing, building capacity to meet international advanced level.

    The project has bro-ken ability is strong, can save transmission corridor, hail, grounding electrodes converter extremely address resources, and improve the transmission efficiency of resources etc. It plays yunnan chuxiong prefecture of lufeng county, west east to guangzhou zengcheng, send a distance of about 1438 km, using HVDC voltage &; plusmn 800kV, rated power transmission 500 million kilowatts. Equipment autonomization rate will reach 60%, plan 2009 unipolar powerstation, 2010 bipolar substation.

April 2010, my Bureau of electricity in high pressure test equipment Anning procurement projects, by the Electric Power Research strict examination panel of experts successfully won the bid, in line with converter stations Yunguang Chuxiong HVDC bipolar transmission projects before the end of June production, should be the actual needs of Chuxiong converter station, the company arranged a sale in time technicians on the morning of May 21 arrived at the test site, together with the related organizations, testing personnel, the use of the projection of converter station equipment, the company has accumulated summary Training Materials (customer version) did show and explain in detail, mainly including the relevant test procedures, equipment, electrical properties, the main working principle, field wiring, the use of notes, solutions to common problems, and discrimination method, and with the presence of test converter station personnel for field test environment for the exchange of communication, training one day.

    22-23, with the Yunnan Electric Power Test & Research Institute in the relevant technical personnel and converter station under the coordination of test personnel to reach the test site, field test environment has become more complex, close to the main circuit 500KV are in normal operation, so the electric field interference and induction voltage are very large, in this environment to be measured in a reliable and accurate test data, test equipment and low anti-interference ability is a big part of the protection test. After-sales personnel understand the situation at the scene with comprehensive analysis of the characteristics of the device itself after the first power line near the case, use our precision loop resistance tester TE600, TE3036 high voltage switching characteristics Tester, TE6600CT polarity voltage characteristic variable ratio Tester and other test equipment, 500KV high voltage circuit breaker Siemens in Germany, Xi'an current transformers and other electrical power equipment, a circuit contact resistance, mechanical and timing characteristics, CT voltage characteristic series of tests.

    The test results are good, got praise staff field test, but also for improving the company's future product and service improvements gained valuable experience working with actual data. The two-day field test site.
