on October 12, device of ice of be in harmony of dc of stationary of first 60 thousand kilowatt is in field test of transformer substation of spring of 500 kilovolt blessing obtains Dou Yun of Guizhou electrified wire netting successful. This mark is worn the development of device of ice of be in harmony of dc of southern electrified wire netting, installation, debug the job to already obtained level sex positive result. = F#e | B_87

It is the directest that at present straight ice drifting be in harmony puts lead of built on stilts on the ice to Fu, effective, reliable be in harmony puts one of means on the ice. Be aimed at the characteristic that calamity of Xue Ning aspic puts on the ice at the beginning of this year, company of southern electrified wire netting relies on method of science and technology actively to increase the capacity of calamity of drive of take precautions against natural calamities of electrified wire netting, fixed the movable type between station of stationary of 60 thousand kilowatt, 25 thousand kilowatt and 500 kilowatt generator car be in harmony of 3 kinds of dc puts device on the ice. Among them, stationary dc be in harmony puts device on the ice to basically be used at be in harmony of 500 kilovolt circuitry to put on the ice, be in harmony of dc of the movable type between the station puts device on the ice to basically be used at be in harmony of 220 kilovolt circuitry to put on the ice. Before this, will mix on August 14 this year on September 5, two kinds of device are in the movable type of 500 kilowatt generator car, movable type between station of 25 thousand kilowatt early or late copper of Guizhou electrified wire netting benevolence Electricity Supply Board and installation of Dou Yun Electricity Supply Board are debugged end.

Will come 12 days on October 11, put on the ice in be in harmony of dc of stationary of 60 thousand kilowatt after device is electrified, technical personnel undertook function test and control protection function are debugged. During debugging, halt use 500 kilovolt blessing uses Ii loop-line means, change to 500 kilovolt Shi Bing carry three-phase weak point to receive undertake small electric current and big electric current experiment taking be in harmony to put circuit on the ice. Final, the be in harmony that as last big electric current experiments puts electric current on the ice with 400 / minute rate rises reach 4000, test line, gold is provided, it is normal that each equipment runs contact and unit of ice of dc be in harmony, blessing of the 500 kilovolt after 15 minutes uses Ii loop-line means highest temperature achieves 43 ℃ , each test data all reachs computational value, whole trial work achieves complete success.
