125-252kV GIS Insulation cylinder

IEE-Business 125-252kV GIS insulation cylinder na a kan wani muhimman komponento a cikin gas insulated metal enclosed switchgear, domin ya kunshi da taimakawa da kuma kula da abubuwan kwafi, amma haka yana da kyau zuwa bayanai masu inganci game da ita:
Muhimmancinta
Abincin: Ana yi daga abincin insulation kamar epoxy resin, wanda yana da kyau zuwa insulation performance da mechanical strength.
Sahihohin: Yana da shaida cylindrical, ana iya amfani da shi a cikin don yanayin abubuwan kwafi da kafin a kan metal casing of GIS. Wasu insulation cylinders zai iya girma da shugaban fanni da sassan da za su iya aiki a cikin hanyar abubuwan installation positions da electrical connection requirements. Misali, a wasu GIS equipment, insulation cylinder zai iya da flanges don yanayin da abubuwan komponento.
Tashar gida: Wasu insulation cylinders zai iya seal vacuum arc extinguishing chamber of the switch, main electrical part of the isolation and grounding switch a cavity sealed with epoxy resin, wanda yana da kyau zuwa space and materials, kuma yana haɗaƙa tsaroce ta aiki.
Talabun Performance
Electrical performance: Yana bukata a yi da kyau zuwa insulation performance da kuma zama mai ban sha'awa a cikin electric field effects a voltage levels of 125-252kV. Misali, rated power frequency 1-minute withstand voltage (relative to ground) of the 252kV GIS insulation cylinder yana da 460kV, da kuma rated lightning impulse withstand voltage peak (1.2/50 μ s) (relative to ground) yana da 1050kV.
Mechanical performance: Yana bukata a yi da kyau zuwa mechanical strength don yanayin weight of conductive components inside GIS equipment, electromagnetic forces, and impact forces generated during operation. Misali, idan short-circuit current ya haɗa, insulation cylinder ya bukata a yi da kyau zuwa integrity of the structure ba su dogara ko lala.
Sealing performance: Insulation cylinder yana bukata a yi da kyau zuwa sealing performance don yanayin SF6 gas inside the GIS equipment ba su fitowa, kuma yana da kyau zuwa insulation and arc extinguishing performance inside the equipment. Yana bukata cewa SF6 gas leakage rate of each compartment of GIS equipment ba su iya bincika 0.5% per year.
Environmental resistance: yana da kyau zuwa different environmental conditions, kamar changes in temperature, humidity, altitude, etc. Misali, a temperature range of -35 ℃ to 40 ℃ and in areas with an altitude not exceeding 2000m, insulation cylinder zai iya aiki da kyau.
Farkon
Insulation isolation: Yana da kyau zuwa insulate the conductive components in GIS equipment from the casing and conductive components of different phases don kula da electrical short circuits and discharges, kuma yana da kyau zuwa safe operation of the equipment.
Supporting and fixing: Yana da kyau zuwa supporting and fixing the conductive components inside GIS equipment don yanayin correct position and spacing, kuma yana da kyau zuwa reliability and stability of electrical connections.
Protect internal components: Yana da kyau zuwa seal key components such as vacuum arc extinguishing chambers inside the chamber don kula da muka da external environmental factors such as dust, moisture, etc., kuma yana haɗaƙa tsaroce da service life of the equipment.
