Takarda na Insulation Performance

• Yadda Aikace-Aikacen Da Take Da Mafi Yawan Tashin Tsari: Fadada AIS voltage transformers ta yi amfani da hawa a matsayin tashin tsari, kuma ana da mafi yawan tashin tsari masu karami, kamar insulating paper da insulating bushings. Idan yawan jiki yake sake zama, yanwuce da yaɗuwar ruwan da ke insulating materials kamar insulating paper zai sake zama, wanda zai haifar da tsarin jirgin ruwa da take da mafi yawan tashin tsari da take da yawan aiki na tashin tsari. Idan yawan jiki yake sake rage, tashin tsari masu karami zai iya sake zama shida, tare da nasarorin kayayyakin mutane suka rage. Idan ana baka wa kayayyaki ko jirgin ruwa, za a iya samun fage, wanda zai haifar da takarda na tashin tsari.

• Yadda Aikace-Aikacen Da Take Da Mafi Yawan Tashin Hawa: Idan yawan jiki yake sake zama, maƙasun hawa zai sake rage, kuma faɗinsu daga gas molecules zai sake zama, da yake haifar da mafi yawan tashin hawa. Wannan yana nufin cewa idan an yi amfani da hukumomi mai yawa, za a iya samun gas discharge phenomena kamar corona discharge da spark discharge, wanda suke haifar da aiki na fadada voltage transformer. Idan yawan jiki yake sake rage, mafi yawan tashin hawa zai sake zama daidai. Amma, yawan jiki mai gaba da gaban da ke rage zai iya haifar da kanjiyar ruwa a wuraren wuraren equipment. Ruwan da ke canza a wuraren equipment zai haifar da mafi yawan tashin wuraren equipment da take da yawan aiki, kuma za su iya haifar da faults kamar flashover.

Takarda na Electrical Parameters

• Yadda Aikace-Aikacen Da Transformation Ratio: Yadda aikace-aikacen da yawan jiki yake sake zama, zai haifar da resistance na winding na fadada voltage transformer. Daga binciken tsarin resistance, resistance na metal materials masu yawan jiki yake sake zama. Yadda aikace-aikacen da winding resistance zai haifar da accuracy na transformation ratio na fadada voltage transformer. Misali, idan yawan jiki yake sake zama, resistance na primary winding zai sake zama. Idan an yi amfani da hukumomi mai yawa na primary, current na primary zai sake rage. Daga binciken electromagnetic induction, secondary voltage zai iya samun yadda, wanda zai haifar da deviation a measured voltage value da take da accuracy na metering da protection devices.

• Yadda Aikace-Aikacen Da Capacitance Parameters: Ana da capacitance components a cikin fadada voltage transformer, kamar bushing capacitance. Yadda aikace-aikacen da yawan jiki yake sake zama, zai haifar da properties na capacitance medium, wanda zai haifar da capacitance value. Yadda aikace-aikacen da capacitance parameters zai haifar da voltage distribution da phase characteristics na fadada voltage transformer, da yake haifar da correct operation na relay protection device.

Takarda na Mechanical Structure

• Thermal Expansion and Contraction: Fadada AIS voltage transformers ana dole da materials masu karami, kuma materials daban-daban suna da coefficients of thermal expansion masu karami. Idan yawan jiki yake sake zama, components masu karami zai iya samun thermal expansion and contraction da take da yawan karami. Idan wannan thermal stress ba zai iya sake zama da effective release, zai iya haifar da loosening na connections bayan components, kamar connection between the winding and the iron core, da kuma connection of the secondary terminal, wanda zai haifar da faults kamar poor contact.

• Sealing Performance: Yadda aikace-aikacen da yawan jiki yake sake zama, zai haifar da sealing structure na fadada voltage transformer. Yawan jiki mai gaba da gaban da ke zama zai iya haifar da aging and deformation na sealing material, wanda zai haifar da sealing performance da take da external dust, moisture, etc. suka zama a cikin interior na equipment, wanda zai haifar da aiki na equipment. Yawan jiki mai gaba da gaban da ke rage zai iya haifar da sealing material zai sake zama hard and brittle, da yake lose its elasticity, wanda zai haifar da sealing effect.
