Thaum cov khoom siv hluav taws xob siv, nws yuav raug txuas tsis raug lossis luv luv. Tsis tas li ntawd, lub zog hluav taws xob nws tus kheej tuaj yeem ua haujlwm tsis zoo thiab ua rau cov zis hluav taws xob tsis zoo. Yog li ntawd, hauv kev tsim thiab tsim cov khoom siv hluav taws xob, kev nyab xeeb specifications yog ib qho tseem ceeb heev. Muaj ob txoj hauv kev tiv thaiv lub zog hluav taws xob, ib qho yog tiv thaiv lwm yam khoom siv los ntawm kev kub hnyiab, thiab lwm yam yog tiv thaiv nws tus kheej los ntawm kev puas tsuaj.
Kev tiv thaiv ntawm cov khoom siv hluav taws xob rau sab nraud yog qhov tseem ceeb tshaj-voltage thiab under-voltage tiv thaiv, uas txhais tau hais tias thaum lub zog tso zis hluav taws xob ntawm lub zog hluav taws xob siab dhau lossis qis dhau los ua qhov txawv txav, lub zog hluav taws xob yuav tsum tsis ua haujlwm. Qhov no yog ib qho tseem ceeb heev rau tag nrho lub tshuab, vim hais tias feem ntau ntawm cov khoom kim heev yog cov tsis yooj yim, thiab nws yog ib qho yooj yim mus hlawv tawm vim high voltage.
Txhawm rau tiv thaiv qhov no, nws yuav tsum tau saib xyuas txhua qhov tso zis hluav taws xob ntawm lub zog hluav taws xob. Tus tsim hluav taws xob tsim txoj hauv kev yog los ua piv txwv qhov tso zis hluav taws xob los ntawm cov qauv ntsuas hluav taws xob, thiab cov teeb liab coj mus kuaj tau txuas nrog rau kev tswj hwm los ntawm kev sib piv. Thaum qhov tso zis voltage yog txawv txav, cov qauv teeb liab yuav tshwm sim tam sim ntawd, thiab qhov chaw tswj yuav raug ceeb toom kom kaw. Qhov no tuaj yeem tiv thaiv qhov kev sib txuas tom qab kawg. Txawm hais tias cov khoom siv hluav taws xob muaj kev tiv thaiv overvoltage yog qhov tseem ceeb heev rau tag nrho lub tshuab. Txhawm rau tiv thaiv kev kub nyhiab tshwm sim los ntawm ntau dhau tam sim no, lub zog hluav taws xob tau nruab nrog lub fuse.
