Ayyuka da Kudin Kirkiro da Amfani da Tashar Bincike na Zane-zanen Lura a GIS

1. Misali da Kudin Farko na Mataimakin Mai Tsarki Don Rukunin GIS

Wannan makaranta ta yi amfani da misalai 126kV GIS don kula da fahimtata masu gina da kuma amfani da mataimakin mai tsarki a cikin gwamnatin GIS. Daga lokacin da wannan babban gwamna ta shiga sakamakon, an yi amfani da shi da kyau, ba a samu matsalolin muhimmanci, kuma yadda ake amfani da shi ya zama mafi kyau.

1.1 Fahimta da Amfaniya Mataimakin Mai Tsarki

A lokacin farko na gwamnati, takamattaka na gwamnatin GIS sun yi tashin bayanin kananan gini da ke faruwa da mataimakin mai tsarki. Yadda ake magana shi shine: idan za a iya koyar da shi a cikin gas SF₆ ko a cikin sauran hawa.

Sashe 1: Koyar da Shugaban Gas Sulfur Hexafluoride

Idan sashe na musamman ya zama, za a iya koyar da mataimakin mai tsarki a cikin gas sulfur hexafluoride mai kyau, kuma abin da ke duni game da shi da kamar kontrola ya zama da suka yi amfani da optical fibers. Amma a cikin yankin gas sulfur hexafluoride mai kyau, ya zama abin da ba ake so in yi amfani da optical fibers a kontrola. Idan za a iya koyar da optical fibers a cikin terminal ports kamar hanyar cables, ya kamata a yi amfani da sana'o'i mai sauƙi da ba ake faɗa; amma wannan sana'o'i ya zama da shi abin da ba ake so in yi amfani da ita, saboda hakan ya zama da shi abin da ke duni game da insulation performance na mataimakin mai tsarki, kuma abubuwan da ba ake so in yi amfani da su.

Sashe 2: Koyar da Shugaban Hawa

Sashe na musamman ba ake bukatar da ka duba abin da ke duni game da kyau, saboda haka baa ci gaba da abin da ke duni game da sana'o'i. Amma za a iya duba abin da ke duni game da tightness na mataimakin, kuma abin da ke duni game da eddy currents wajen kawo ma'ana da shiga da shaida, da kuma abin da ke duni game da shaida da za a iya shafi.

Ba da kula da kula da kula, takamattaka na gwamnatin GIS sun yan sashe 2. Sashe na musamman ya kunshi amfani da safety, reliability da stability na gwamnati, kuma ya duba abin da ke duni game da implementation.

2. Bayanin Da Suke Halarta Masu Abin Da Ba Ake So In Yi Amfani Da Su Na Sashe
Design da Connection

Ba da kula da kula da kula, ta yi amfani da design structure na mataimakin mai tsarki da traditional electromagnetic current transformer, an yi amfani da mataimakin mai tsarki a cikin hawa, kuma ta yi amfani da abubuwan da su:

Ta yi amfani da flange mai yawa, ta koyar da mataimakin mai tsarki a cikin flange, kuma ta koyar da optical fiber daga yawan flange. Haka, connection part bayan optical fiber da mataimakin mai tsarki ya zama a cikin mataimakin, kuma abin da ke duni game da flanges na transformers na sauran ya zama metal.

Saboda eddy currents za a iya shiga a lokacin da mataimakin ya yi amfani, wanda za a iya shiga da shaida da voltage na mataimakin mai tsarki. Don halartar wannan abin, an yi amfani da electrostatic spraying treatment a metal contact surfaces na flanges, don in kara eddy current loop da kuma in kula tightness na sulfur hexafluoride gas.

Simulation da Verification na Electric Field

Saboda ta yi amfani da flange structure a design, electric field distribution na mataimakin mai tsarki ya zama. Don in kula effectiveness na sashe, ya kamata a yi amfani da simulation calculation tools (kamar ANSYS software) don in kula testing da analysis work. An yi amfani da ANSYS don in kula field strength experiments a metal rings da conductors na flanges. Lightning impulse voltage da ake amfani a experiment shine 150kV. Ba da kula da kula da kula, ANSYS software ya nuna cewa field strength a edge parts na flange da shielding cover shine mafi yawa, kuma maximum value ya zama 20kV/mm. Wannan result ya zama da ya fi shirin da kula da kula da kula, saboda project team ya yi research da scientific da precise simulation calculations.

Yanzu, wannan gwamnati ya yi amfani da shi da kyau, kuma ya zama da shaida. Yanzu, a China, an yi amfani da mataimakin mai tsarki da shaida. Amma, a cikin abin da ke duni game da high voltage levels, akwai abin da ke duni game da reducing the influence of birefringence caused by stress and temperature, ensuring the long-term stable operation of the system, and further improving the measurement accuracy, wadannan abubuwan za a iya shafi a cikin ingantaccen.

3. Tausayi

Ba da kula da kula da kula, ta yi amfani da discussion na whole process from scheme selection, implementation to problem solving na mataimakin mai tsarki a cikin gwamnatin GIS, an yi amfani da shi da shaida. Mataimakin mai tsarki na musamman ya kunshi advantages daga traditional electromagnetic current transformer, kuma yadda ake amfani da shi ya zama da shaida. Akwai manufacturers da users wadanda suka yi amfani da shi. Ya kamata a cikin lokaci mai tsawo, mataimakin mai tsarki za a iya koyar da electromagnetic current transformer, kuma technology za a iya yi amfani da shi da shaida, kuma za a iya kula transformer technology da shaida.
