Mai Transformer GK

Технические характеристики

Abun da ke ciki da kaddarorin darajar mai na mai canzawa GK an ƙaddara su ta ma'auni na GOST 982-80. Waɗannan dokokin suna nufin:

• Babban aikin rufin lantarki, gami da maɗaukakin yanayin zafi.
• Kasancewar abubuwan haɓakar antioxidant (ionol), ban da lalata a ƙarƙashin babban ƙarfin lantarki.
• Rashin alkalis mai narkewa da ruwa da ƙazanta na inji.
• Ƙarfafa alamun danko a cikin takamaiman kewayon zafin jiki.
• Mafi ƙarancin abun ciki na ions acid kyauta.

Madaidaitan ƙa'idodin physico-chemical don samfurin da aka kwatanta sune:

1. Yawan yawa, kg / m³, a dakin da zafin jiki - 890± 5.
2. Kinematic danko, mm²/ s, a zazzabi na 50 ^°C, ba kasa - 9 ... 10.
3. Kinematic danko, mm²/s a mafi ƙanƙancin shawarar zafin aikace-aikacen -30 ^°C, bai wuce 1200 ba.
4. Ragowar acid na dangi dangane da KOH, bai wuce 0,01 ba.
5. filashi, ^ºC, ba kasa da 135 ba.
6. Zazzabi mai kauri, ° C, bai kasa -40 ba.
7. Ƙayyadadden ƙididdiga na iskar shaka bayan ƙarewar lokacin garanti don amfani da samfurin, bai wuce 0,015 ba.

Rashin wutar lantarki don GK mai mai shine 2 kV, wanda ya cika cikakkiyar buƙatun fasaha na GOST 6581-75.

Menene bambance-bambance tsakanin mai na GK da VG?

VG mai ma'adinai an yi niyya don amfani da shi a cikin shigarwar lantarki - bankunan capacitor, ballasts da relays, waɗanda aka tsara don ƙarfin aiki har zuwa 1,15 kV. Wannan shi ne saboda kasancewar inhibitory additives a cikin abun da ke ciki na man fetur, wanda ya rage girman matakan lalata, amma a lokaci guda ya rage kaddarorin dielectric.

Mai Transformer GK ana la'akari da Semi-synthetic, tunda yana ƙunshe da ƙara yawan adadin anti-lalata, dielectric da ƙari masu hanawa. Anyi hakan ne domin a yi amfani da mai mai tsami da aka fi samun dama daga ma'ajiyar Yammacin Siberiya wajen samar da samfurin ƙarshe. Don haka, yana yiwuwa a kula da ƙimar zafin jiki mai ƙarfi a cikin rufaffiyar juzu'i na masu canji masu ƙarfi. Duk da haka, a cikin wannan yanayin, juriya na lalata na sassan karfe na na'urorin da ke cikin wanka tare da man GK ya ragu.

Shawarwari na fasaha suna ba da shawarar amfani da man GK har sai an maye gurbin na tsawon lokacin da bai wuce shekara guda ba. Ana gudanar da sarrafa ingancin samfur bisa ga halaye na gani - nuna gaskiya, kasancewar laka mai ƙarfi - da kasancewar ions acid wuce haddi. Ga mai GK, wannan ƙimar shine 0,015 (sama da wannan alamar, ƙarfin rushewar da aka yarda ya faɗi zuwa 750 V). A cikin man VG, saboda rashin ions kyauta, kusan babu tabarbarewar aiki cikin lokaci.

Fasalolin aikace-aikacen da sake dubawa

Ingancin man transfoma na GK ya dogara da masana'anta. Matsakaicin adadin mahadi na sulfur shine na yau da kullun don samfuran da aka ƙera a JSC Ufaneftekhim, kamfanin Kstovo Nefteorgsintez da matatar Omsk. Sauran masana'antun suna ƙara yawan adadin abubuwan da ke jure gas zuwa samfurin ƙarshe, wanda ke ƙara yawan zafin jiki da aka yarda, amma yana rage aikin dielectric. Irin nau'in mai a matsayin mai canzawa gabaɗaya kuma yana bin ka'idodin GOST 982-80, amma ba a ba da shawarar ga ƙarfin filin lantarki mai girma ba.

Farashin kowace lita

Tare da sayayya mai yawa, farashin ganga na mai (lita 200) zai kasance daga 14000 zuwa 16000 rubles. Farashin dillali na man GK a kowace lita (lokacin da aka cika shi a cikin gwangwani 20 l) daga 140 ... 150 rubles.
