Xaiv qhov ntsuas thiab qhov xav tau ntawm qhov ntsuas hluav taws xob
Qhov kev xaiv Performance index ntawm tus tiv thaiv voltage tester:
Qhov tseem ceeb tshaj plaws hauv kev xaiv lub ntsuas hluav taws xob tiv thaiv hluav taws xob yog ob qhov ntsuas, qhov siab tshaj qhov tso zis hluav taws xob tus nqi thiab qhov siab tshaj plaws lub tswb tam sim no tus nqi yuav tsum ntau dua li tus nqi hluav taws xob thiab lub tswb tam sim no koj xav tau. Feem ntau, cov khoom kuaj tus qauv qhia txog qhov siv high voltage tus nqi thiab lub tswb ntsuas tam sim no tus nqi. Yog hais tias qhov kev thov voltage siab dua thiab lub tswb ntsuas tam sim no loj dua, ces lub zog ntawm cov kauj ruam-up transformer ntawm qhov ntsuas hluav taws xob tiv thaiv yuav tsum muaj ntau dua. Feem ntau, lub zog ntawm cov kauj ruam-up transformer ntawm qhov ntsuas qhov ntsuas hluav taws xob yog 0.2kVA, 0.5kVA, 1kVA, 2kVA, 3kVA, thiab lwm yam. Cov hluav taws xob siab tuaj yeem ncav cuag kaum txhiab volts. Lub tswb nrov tam sim no 500mA-1000mA, thiab lwm yam. Yog li ntawd, koj yuav tsum xyuam xim rau ob qhov ntsuas no thaum xaiv lub ntsuas hluav taws xob tiv taus. Yog tias lub zog loj dhau lawm, nws yuav ua rau cov khoom pov tseg, thiab yog tias lub zog me me dhau lawm, qhov ntsuas hluav taws xob tiv thaiv tsis tuaj yeem txiav txim siab seb nws puas tsim nyog lossis tsis tau. Raws li IEC414 lossis (GB6738-86), txoj kev siv hluav taws xob ntawm kev xaiv lub ntsuas hluav taws xob tiv thaiv tau suav tias yog kev tshawb fawb ntau dua. "Ua ntej kho qhov tso zis hluav taws xob ntawm qhov ntsuas hluav taws xob tiv thaiv hluav taws xob mus rau 50 feem pua ntawm cov nqi teev, thiab tom qab ntawd txuas cov khoom ntsuas ntsuas. Thaum pom qhov ntsuas hluav taws xob poob qis dua 10 feem pua ntawm cov nqi hluav taws xob, lub zog ntawm qhov ntsuas hluav taws xob tiv thaiv yog txiav txim siab. txaus. "Qhov ntawd yog, yog tias tus nqi hluav taws xob ntawm qhov ntsuas qhov ntsuas hluav taws xob ntawm cov khoom yog 3000 volts, ua ntej kho qhov tso zis hluav taws xob ntawm qhov ntsuas hluav taws xob tiv thaiv rau 1500 volts thiab tom qab ntawd txuas cov khoom kuaj, yog tias tus nqi ntawm cov zis voltage poob. ntawm qhov ntsuas qhov ntsuas hluav taws xob tsis siab tshaj 150 volts, ces lub zog ntawm qhov ntsuas hluav taws xob tiv thaiv yog txaus. Muaj ib qho kev faib tawm ntawm qhov chaw nyob ntawm qhov khoom kuaj thiab cov casing. Lub capacitor muaj CX capacitive reactance, thiab thaum AC voltage siv hla CX capacitor, tam sim no yuav raug ntxias.
Qhov loj ntawm qhov tam sim no yog proportional rau lub peev xwm ntawm CX capacitor thiab tus nqi siv hluav taws xob. Thaum qhov tam sim no loj dua los yog tshaj qhov tso zis ntau tshaj tam sim no ntawm qhov ntsuas hluav taws xob, tus ntsuas hluav taws xob tsis tuaj yeem txiav txim siab seb qhov kev xeem puas tsim nyog lossis tsis tau.
