Yuav ua li cas nyeem qhov voltage nrog lub ntsuas hluav taws xob
Cov ntawv ntsuas ntsuas digital yog ib hom kev xeem cwj mem, uas yog cov cuab yeej hluav taws xob thiab hluav taws xob, thiab siv los ntsuas seb cov hlau puas raug them. Tus cwj mem lub cev ntawm cov ntawv ntsuas ntsuas digital muaj lub teeb ci LED, uas tuaj yeem nyeem qhov ntsuas qhov ntsuas hluav taws xob. Thaum ntsuas cov hluav taws xob hluav taws xob, lub teeb hluav taws xob hluav taws xob muaj qhov voltage ntawm U=220V nruab nrab ntawm cov hluav taws xob hluav taws xob thiab hauv av. Tam sim no (uas yog, tam sim no dhau los ntawm tib neeg lub cev) yog qhov tsawg heev, feem ntau tsawg dua 1 milliampere. Thaum xws li ib tug me me tam sim no dhau los ntawm tib neeg lub cev, nws yuav tsis ua mob rau tib neeg, thiab thaum xws li ib tug me me tam sim no hla lub neon noob ntawm lub xeem cwj mem, lub neon noob yuav emit teeb. .
Cov lus qhia rau kev siv cov nyees khawm:
(Ib tug yuam sij) DIRECT, ncaj qha ntsuas khawm (nyob deb ntawm lub vijtsam LCD), uas yog, thaum siv lub ntsis kom ncaj qha rau ntawm kab, thov nias lub pob no;
(B yuam sij) INDUCTANCE, inductive ntsuas khawm (ze rau ntawm lub vijtsam LCD), uas yog, thaum siv me ntsis kom nkag siab cov kab sib cuag, thov nias lub pob no.
Nco tseg: Txawm hais tias yuav luam tawm ntawm tus cwj mem hluav taws xob li cas, thov nco ntsoov tias qhov deb ntawm lub vijtsam LCD yog lub khawm ntsuas ncaj qha; ib qho ze rau lub LCD yog lub khawm sensor!
Cov cwj mem ntsuas no yog tsim nyog rau kev tshawb nrhiav ncaj qha ntawm 12-250v AC thiab DC thiab tsis pom kev ntawm cov xaim nruab nrab, theem xaim thiab qhov tawg ntawm AC lub zog. Nws kuj tseem tuaj yeem ntsuas qhov txuas ntxiv ntawm cov conductors tuag.
Direct detection:
a. Tus lej kawg yog ntsuas tus nqi hluav taws xob;
b. Thaum nws tsawg dua 70 feem pua ntawm cov khoom siv high-txiav zaub, nws yuav tso saib tus nqi txiav qis;
c. Thaum ntsuas tam sim no ncaj qha, kov lwm tus ncej nrog koj txhais tes;
Indirect detection:
Nias thiab tuav tus yuam sij B, thiab nqa qhov me ntsis ze rau ntawm txoj hlua hluav taws xob. Yog hais tias lub hwj chim qaum raug them, lub cim hluav taws xob siab yuav raug muab tso rau ntawm cov zaub ntawm tus cwj mem digital.
Breakpoint detection:
Nias thiab tuav tus yuam sij B, thiab thaum txav ntsug raws cov xaim, qhov chaw uas tsis muaj zaub nyob rau hauv lub qhov rais zaub yog qhov tawg.
Tus cwj mem tshiab digital zaub tuaj yeem kuaj 12V, 36V, 55V, 110V thiab 220V. Feem ntau, nias rau saum tus cwj mem ntsuas ntsuas qhov ntsuas hluav taws xob, thiab cov zaub siab tshaj plaws yog qhov ntsuas qhov ntsuas tam sim no; hauv qab yog qhov kev ntsuam xyuas induction los xyuas cov insulators Nyob rau hauv rooj plaub ntawm Circuit Court breakage, qhov no yog raws li kev paub.
Kev ntsuas hluav taws xob:
1. Kev kuaj pom ntau yog 12-250V AC/DC voltage.
2. Kov lub khawm ntsuas ncaj qha (DIRECT), thiab cov hlau pem hauv ntej kawg ntawm tus cwj mem ntsuas kov cov khoom yuav tsum tau kuaj. Tus cwj mem xeem tau muab faib ua tsib theem: 12V, 36V, 55V, 110V thiab 220V. Tus nqi kawg ntawm lub vijtsam LCD yog qhov ntsuas qhov ntsuas hluav taws xob (Thaum nws tsawg dua 70 feem pua ntawm cov khoom siv high-end, tus nqi qis kawg yog tso tawm).
3. Thaum ntsuas tsis yog hauv av ncaj qha tam sim no, tes yuav tsum kov lwm lub electrode (xws li qhov zoo lossis qhov tsis zoo).
Induction detection:
1. Maj mam kov lub induction, ntsuas qhov tawg (INDUCTANCE) khawm, thiab cov hlau pem hauv ntej kawg ntawm tus cwj mem ntsuas yog ze rau cov khoom kom kuaj pom. Yog tias "high voltage symbol" tshwm rau ntawm qhov screen, nws txhais tau hais tias cov khoom yog nqa alternating tam sim no.
2. Thaum ntsuas cov hlau tsis sib txuas, maj mam kov lub induction, ntsuas qhov tawg (INDUCTANCE) khawm, cov hlau pem hauv ntej kawg ntawm tus cwj mem xeem yog nyob ze rau lub insulating txheej txheej ntawm cov hlau, muaj qhov tshwm sim tsis sib xws, thiab "high voltage cim" disappears ntawm lub breakpoint.
3. Siv txoj haujlwm no kom yooj yim paub qhov xoom thiab theem kab (qhov kev ncua deb ntawm kab yuav tsum tau nce ntxiv thaum ntsuas cov kab sib txuas). Tshawb xyuas microwave tawg thiab to.
Cov kev ceev faj:
Cov nyees khawm tsis tas yuav tsum tau nias nyuaj, thiab ob lub khawm sim tsis tuaj yeem kov tib lub sijhawm thaum lub sijhawm kuaj, txwv tsis pub qhov kev xav tau thiab cov txiaj ntsig kev xeem yuav raug cuam tshuam.
