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.
