Hluav taws xob ntes, tseem hu ua Surge Protective Device (SPD), Surge Protector Device), Nws yog ib qho khoom siv hluav taws xob uas muab kev tiv thaiv kev ruaj ntseg rau ntau yam khoom siv hluav taws xob, cov cuab yeej siv, thiab cov kab sib txuas lus. Thaum muaj qhov hluav taws xob tam sim no lossis qhov hluav taws xob tam sim no tshwm sim hauv hluav taws xob los yog kab sib txuas lus vim muaj kev cuam tshuam sab nraud, SPD tuaj yeem ua thiab hloov mus rau lub sijhawm luv luv, yog li zam kev puas tsuaj rau lwm yam khoom siv hauv Circuit Court los ntawm qhov surge.
Ua xob ntes yuav tsum tau muab ntsia rau hauv lub thawv sab nraud ntawm lubchaw nres tsheb them nqi?
Teb: Feem ntau tsis xav tau. Rau AC charging chaw nres tsheb, muaj ib qho hluav taws xob tiv thaiv hluav taws xob; Rau DC charging chaw nres tsheb, ib qho hluav taws xob sib cais raug teeb tsa ntawm AC input kawg hauv qhov chaw them nyiaj.

Lub teeb hluav taws xob ntes hluav taws xob yog ib theem ib ntus tiv thaiv hluav taws xob hluav taws xob raws li varistors thiab cov roj tso tawm. Nws muaj qhov sib xyaw ua ke sib xyaw ua ke uas muaj peb lub varistors thiab ib lub raj xa tawm, muab kev tiv thaiv tag nrho rau hom hom thiab hom sib txawv. Lub varistor MOV4 txuas nrog rau qhov sib npaug nrog cov khoom siv hluav taws xob L thiab N, feem ntau yog clamp qhov voltage ntawm L thiab N kab. Cov varistors MOV1 thiab MOV3 txuas nrog hauv cov koob nrog lub raj xa tawm FDG1 thiab hauv av. Cov kev sib txuas ntawm MOV1 thiab FDG1 feem ntau yog siv los tso tawm cov surge tam sim no ntawm N kab, thaum lub koob txuas ntawm MOV3 thiab FDG1 feem ntau yog siv los tso tawm cov surge tam sim no ntawm L kab. Thaum overvoltage tshwm sim ntawm L / N kab, qhov kev tiv thaiv ntawm varistor txo qis, thiab cov surge tam sim no tau tawm mus rau hauv av los ntawm cov raj xa tawm FDG1 los tiv thaiv lub zog ntawm kev puas tsuaj. Thaum lub siab-rhiab heev luv Circuit Court tsis ua hauj lwm, fuse F4 melts, disconnecting lub luv luv Circuit Court.
