Plaub yam tseem ceeb ntawm cov khoom siv tiv thaiv kev kub ntxhov (SPD)

Cov cuab yeej tiv thaiv hluav taws xob (SPD) yog ib lub cuab yeej hluav taws xob uas muab kev tiv thaiv kev nyab xeeb rau ntau yam khoom siv hluav taws xob, cov cuab yeej siv, thiab cov kab sib txuas lus. Thaum muaj hluav taws xob tam sim ntawd lossis hluav taws xob nce siab hauv cov kab hluav taws xob lossis cov kab sib txuas lus vim muaj kev cuam tshuam sab nraud, lub cuab yeej tiv thaiv hluav taws xob tuaj yeem ua thiab hloov pauv hluav taws xob kom tiv thaiv kev puas tsuaj rau lwm yam khoom siv hauv lub voj voog. Muaj plaub qhov tseem ceeb uas yuav tsum xav txog thaum tshuaj xyuas SPD:

1. Qhov siab tshaj plaws ntawm lub zog ua haujlwm tas mus li (Uc) Uc yog hais txog qhov siab tshaj plaws ntawm lub zog rms (RMS) lossis DC uas siv tau rau hom kev tiv thaiv SPD. Yeej, nws sawv cev rau qhov ntsuas hluav taws xob ntawm SPD. Tus nqi Uc muaj feem cuam tshuam rau lub neej ua haujlwm thiab qib kev tiv thaiv hluav taws xob ntawm SPD. Txawm hais tias kev xaiv tus nqi Uc siab dua tuaj yeem ua rau lub neej ua haujlwm ntawm cov khoom ntev dua, nws tseem yuav ua rau lub zog seem ntxiv, uas ua rau puas tsuaj rau cov khoom tiv thaiv.

2. Tus nqi tam sim no (In) In yog qhov siab tshaj plaws ntawm 8 / 20μs tam sim no nthwv dej ntws los ntawm lub tshuab tiv thaiv hluav taws xob. Tus qauv SPD qhia txog cov nqi In. Thaum tsim thiab tsim cov qauv tshwj xeeb ntawm SPD kom ua tiav qib tshwj xeeb, tus nqi In sib xws raug xaiv los ntawm cov koob In rau kev sim. Kev sim ua tiav txiav txim siab tus nqi xaiv ua tus nqi In ntawm SPD.

3. Qhov siab tshaj plaws tam sim no hauv chav kawm II xeem (Imax) Imax sawv cev rau qhov siab tshaj plaws tam sim no ntawm 8 / 20μs tam sim no nthwv dej ntws los ntawm tus tiv thaiv kev co hauv chav kawm II xeem. Txawm hais tias qhov kev txhais ntawm qhov parameter no zoo ib yam li qhov nominal discharge tam sim no (In), tus qauv SPD muab ntau yam ntawm Imax tus nqi nyob ib sab ntawm In series, thiab nyob rau hauv tib theem, Imax > In. Yog li ntawd, SPD dhau qhov kev xeem ntawm ib qib In tshwj xeeb tsis lav tias SPD nrog tib qib Imax kuj yuav dhau qhov kev xeem. Txawm hais tias In thiab Imax yog ob qho tib si qhov siab tshaj plaws ntawm 8 / 20μs tam sim no nthwv dej, qhov siab tshaj plaws thiab tus lej ntawm lub sijhawm tam sim no dhau thaum lub sijhawm xeem yog txawv.

4. Qib tiv thaiv hluav taws xob (Saum), tseem hu ua hluav taws xob seem, hais txog hluav taws xob hla SPD thaum tam sim no nrog lub waveform tshwj xeeb ntws los ntawm SPD tom qab SPD pib. Qhov parameter no yog qhov tseem ceeb los tiv thaiv lub zog hluav taws xob ntawm cov khoom siv tiv thaiv thiab yuav tsum qis dua lub zog hluav taws xob ntawm cov khoom siv tiv thaiv.

Kev nkag siab thiab kev txheeb xyuas cov kev ntsuas no yog qhov tseem ceeb rau cov khoom siv tiv thaiv hluav taws xob. Kev txiav txim siab zoo thiab kev xaiv SPDs raws li cov kev ntsuas no yuav ua kom ntseeg tau tias lawv muab kev tiv thaiv zoo rau cov khoom siv hluav taws xob, cov twj paj nruag thiab cov kab sib txuas lus, thaum kawg txo qhov kev puas tsuaj los ntawm kev nce thiab nce siab.
