Yog tias koj tab tom nrhiav cov khoom siv hluav taws xob hloov hluav taws xob rau cov chaw kuaj hluav taws xob hauv Suav teb, Lub Xeev Grid substation, lossis ib qhov kev xa tawm nrog ob txoj kev ua raws cai, "SH / T standard" yog ib kab lus uas koj yuav pom ntawm yuav luag txhua daim ntawv teev cov ntaub ntawv. SH / T cov lej yog cov qauv kev lag luam petrochemical uas tau tshaj tawm hauv Suav teb SH series. Lawv tsis hloov GB/T lub teb chaws tus qauv lossis DL/T lub zog- txoj hauv kev lag luam-tab sis rau ob peb lub hauv paus insulating- roj, lawv tseem yog cov ntaub ntawv siv cov cuab yeej tsim ua ib puag ncig.
SH/T 0206-1992 - Oxidation Stability Tester
Qhov no yog tus qauv ncaj nraim khi rau lub tshuab muaj npe. Nws qhia txog 164- teev oxidation khiav: 25 g ntawm roj, oxygen bubbling los ntawm cov qauv, ib tug tooj liab catalyst, thiab ntsuas tag nrho cov sludge thiab acidity tom qab ntawd. Cov txheej txheem rov qab mus rau IEC 74 (1974). Benchtop units ua lag luam raws li SYD{12}}0206 los yog GD{14}}0206 oxidation stability testers yog dimensioned rau SH/T 0206-feem ntau yog rau parallel da dej, hlau thaiv cua sov rau ± 0.2℃, thiab flow-controlled oxygen kab. Yog tias koj qhov kev pabcuam QC taug qab sai npaum li cas hauv kev pabcuam roj cov ntaub ntawv sludge, qhov no yog tus qauv koj tus neeg kuaj yuav tsum ua raws.
SH/T 0207 / NB/SH/T 0207-2010 - Trace Moisture Analyzer
Txoj kev xyoo 1992 Karl Fischer (SH/T 0207) rau insulating - roj cov ntsiab lus tau hloov dua tshiab hauv 2010 los ntawm NB/SH/T 0207-2010, uas ua raws li coulometric Karl Fischer titration{{9} tib lub hauv paus ntsiab lus ntawm cov dej tsis siv neeg tom qab. Hauv kev xyaum, ntau cov ntaub ntawv tseem hais txog SH / T 0207 rau kev sib raug zoo qub qub. Rau kev khiav-kev saib xyuas roj raws li GB/T 7595-2017, kev txwv tsis pub ya raws feem ntau cuam tshuam nrog GB/T 7600 ib yam, yog li paub meej tias tus lej twg koj cov npe tshuaj xyuas cov npe ua ntej yuav khoom.
SH/T 0304-1999 - Corrosive Sulfur Test
Cov qauv no suav nrog corrosive sulfur nyob rau hauv cov roj hluav taws xob hluav taws xob: ib qho polished tooj liab strips tiv tauj cov roj ntawm 140 degree, thiab discoloration yog graded tiv thaiv lub rooj siv. Nws ua ke nrog tooj liab- strip corrosion testers thiab cov chromatograph tshwj xeeb workflows suav nrog hauv transformer- cov kev pab cuam roj zoo.
Dab tsi SH/T tsis npog - thiab qhov twg tsis meej pem pib
Dielectric breakdown voltage-qhov kev ntsuam xyuas feem ntau cov neeg ua haujlwm koom nrog "transformer roj tester"- poob qis dua GB / T 507 (lub zog- zaus tawg) thiab DL / T 429.9 hauv lub zog hluav taws xob, tsis yog SH/T. ASTM D877, D1816, thiab IEC 60156 tswj electrode geometry thiab ramp tus nqi rau BDV cov cuab yeej muag thoob ntiaj teb. Ib qho tsis siv neeg 80 kV BDV tester yog li GB / T / IEC / ASTM sib tham; oxidation da dej los yog Karl Fischer titrator yog kev sib tham SH/T.
