Kev Txuas Lus

RST 25 tuaj yeem txuas tau raws li hauv qab no hauv cov teeb duab teeb tsa:
FlG1: Kev sib txuas ntawm cov relay ua ntej kev ua haujlwm.
Thaum cov relay tau txuas nrog xws li hauv FIG 1, peb lub teeb daj LED L1, L2 thiab L3 teeb tawm thaum lub zog mov A1 theem L, A2 nruab nrab, thiab peb theem "L1," L2 ″ thiab "L3 ″ txuas nrog kom zoo. Cov.
Yog tias tsis muaj nyob hauv overvoltage, theem tsis ua haujlwm ntawm theem kab hluav taws xob, lub teeb ntsuab LED teeb, (cov davhlau ya nyob 11 thiab 14 raug kaw) thiab cov relay tau npaj rau kev ua haujlwm.
FIG2: Kev sib txuas ntawm lub relay tom qab ua haujlwm.
Thaum cov relay tau txuas nrog nyob rau hauv FIG 2, (lub zog hluav taws xob Al theem L, A2 Nruab Nrab txuas nrog tau zoo) tom qab kev ua haujlwm, peb theem "L1 ″," L2 ″ thiab "L3 ″ txuas nrog, thiab tsis muaj ib yam dab tsi nyob hauv overvoltage, theem poob, theem ua ntu zus, lub teeb ntsuab LED teeb (xaus 11 thiab
14are kaw) thiab qhov xa tawm yog npaj rau kev khaws tus kheej.
Nws tseem muaj peev xwm txuas tau lub zog muab hluav taws xob tom qab ua haujlwm hauv FIG2.
Los ntawm ob lub ntsej muag FIG 1 thiab 2, lub davhlau ya nyob twg “PE” yuav tsum yog av.

Cuag tsis taus
Qhov xav tau ntawm qhov qis qis dua tuaj yeem hloov kho kom tsawg rau -25% UN.

Siab dua
Qhov xav tau overvoltage cov kev txwv yuav raug kho kom nce mus txog + 25% UN.

Asymmetry
Thaum kho kho dhau-thiab undervoltage txwv, lub asymmetric txwv kuj tseem hloov kho.

Ncua Sijhawm
Lub sijhawm hloov pauv thaum lub sijhawm tuaj yeem hloov kho los ntawm tus tsim hluav taws xob "Lub Sij Hawm Qeeb" txij li 0.1… .5 lub vib nas this. Nrog txoj haujlwm no nws yog tuaj yeem hloov kho lub sijhawm rau kev txheeb xyuas qhov tsis ua tiav.

Tus Tswj Xov Tooj
Yog tias ib theem tsis ua haujlwm thaum lub sijhawm ua haujlwm thaum lub sijhawm thauj khoom lossis ib qho kev sib cuag ntawm tus hu lossis hluav taws xob sib kis yog qhov tsis xws luag, (kev sib chwv lossis sib chwv sib luag), RST 25 lees paub qhov tsis ua haujlwm, thiab tseem muaj qhov tawm tswv yim voltage, thiab hloov mus rau ntawm qhov teeb tsa ntawm “Lub sij hawm qeeb”
RST 25 tswj hwm lub sijhawm hloov. Yog tias muaj theem tsis ua haujlwm thaum lub sijhawm ua haujlwm lub kaum sab xis los ntawm lub tswv yim voltage yog 30 ° thiab RST 25 lees paub qhov tsis ua haujlwm.
