qhib. Lub hom phiaj ntawm lub fuse yog khaws cov tam sim no ntau dhau los ntawm kev khiav ntawm hluav taws xob hluav taws xob thiab tiv thaiv kev puas tsuaj rau cov khoom hauv Circuit Court. Thaum lub fuse tshuab no yog vim ntau dhau tam sim no tau khiav dhau nws. Tshuab lub fuse nres qhov tam sim no los ntawm kev qhib lub voj voog.
Thaum xaim hluav taws xob coated nrog solder txheej txheem no hu ua?
Tinning yog txheej txheem ntawm kev siv cov hlau nplaum kom yaj cov hlau nyob ib ncig ntawm cov xaim hluav taws xob.
Tus qauv multimeter tsis ntsuas dab tsi?
Nws yog siv los ntsuas peb qhov yooj yim hluav taws xob yam ntxwv ntawm voltage, tam sim no, thiab tsis kam. Nws kuj tseem tuaj yeem siv los ntsuas kev txuas ntxiv ntawm ob lub ntsiab lus hauv hluav taws xob hluav taws xob. Multimeters tsis tuaj yeem siv rau ntsuas hluav taws xob ntau xws li zaus, nqi thiab lwm yam.
Yuav ua li cas tam sim no ua lub tuam txhab hluav taws xob hluav taws xob nqa?
Cov kab sib kis feem ntau yog high-voltage peb-theem alternating tam sim no (AC), txawm tias ib theem AC qee zaum siv hauv kev tsheb ciav hlau hluav taws xob. High-voltage direct-current (HVDC) thev naus laus zis yog siv rau kev ua haujlwm zoo dua nyob rau qhov deb heev (feem ntau pua mais).
Lub cev muaj zog yog dab tsi?
Hauv DC yooj yim thiab universal motors, lub rotor tig hauv tus stator. Lub rotor yog ib lub kauj txuas nrog lub zog hluav taws xobthiab tus stator yog cov hlau nplaum ruaj khov lossis electromagnet.

Dab tsi yog qhov txawv ntawm lub tshuab hluav taws xob thiab lub tshuab hluav taws xob?
Gramophone: Txhua lub suab kaw suab, lossis cov cuab yeej ua si yav dhau los-cov suab kaw, tshwj xeeb tshaj yog tias nws siv lub tiaj tiaj tiaj. Phonograph: Txhua lub suab kaw suab, lossis cov cuab yeej siv rau kev ua si cov suab uas tau kaw dhau los, tshwj xeeb tshaj yog tias nws siv lub tog raj kheej tig.
Puas yog lub tshuab hluav taws xob xav tau lub tshuab hluav taws xob?
Diesels tsis xav tau lawv - pob tseg li qub / tshuab tawm li qub yog tsim los rau qhov chaw nruab nrab ntawm lub turbo thiab lub throttle. Nyob rau hauv ib tug petrol engine, ntawm siab boost, thaum koj snap lub throttle kaw lub turbo tseem tig.
Puas hluav taws xob hluav taws xob puas tsim hluav taws xob?
Coal feem ntau siv roj los tsim hluav taws xobhauv Tebchaws Meskas. Hauv cov chaw tsim hluav taws xob hluav taws xob hluav taws xob, cov hluav taws xob bituminous, subbituminous thee, lossis lignite raug hlawv. Cov cua kub uas tsim los ntawm kev sib xyaw ntawm cov thee yog siv los hloov cov dej mus rau hauv qhov chaw siab zog, uas tsav lub turbine, uas tsim hluav taws xob.
Lub tshuab hluav taws xob hluav taws xob tsim hluav taws xob li cas?
Piav seb lub twj hluav taws xob hluav taws xob tsim hluav taws xob hla lub membrane li cas. Los ntawm pum electrons hla lub membrane, sab uas cov electrons raug tshem tawm muaj qhov zoo dua, thaum sab tau txais cov hluav taws xob ntau muaj qhov tsis zoo.
Puas yog lub tshuab hluav taws xob puas muaj lub tshuab hluav taws xob?
Vim li cas lub tshuab hluav taws xob sab hauv combustion yuav tsum tsis muaj lub tshuab hluav taws xob los ua kom cov roj tsis zoo li roj av? Spark plugs yog siv nyob rau hauv cov roj cav mus ignite cov pa roj sib tov whereas nyob rau hauv diesel engines lub xub ntiag ntawm lub txim plugs yog tsis tsim nyog.
