Lub Tuam Txhab Txuj Ci

FAQ

1) Peb lub koom haum siv ntau hom relay, nrog rau cov qauv tam sim no thiab voltage relays, nruab nrab relays nrog tuav coils, thiab tshwj xeeb sib txawv relays. Cov cuab yeej no puas tuaj yeem ntsuas tag nrho cov hom no?

Teb:
Qhov ntsuas qhov ntsuas qhov ntsuas tag nrho npog tag nrho cov relay hom hais yam tsis tas yuav tsum muaj cov cuab yeej tshwj xeeb ntxiv. Cov ntsiab lus tshwj xeeb compatibility yog raws li hauv qab no:
Conventional Relays: Txhawb nqa tam sim no thiab voltage ntsuas relays, ua kom muaj kev ntsuas meej ntawm cov nqi khaws khoom, tso tawm tus nqi, thiab tso tawm coefficients. Lub sij hawm relays 'siv qhov tseem ceeb, tso tawm qhov tseem ceeb, thiab lub sijhawm ua haujlwm kuj tuaj yeem kuaj ncaj qha.
Intermediate relays nrog tuav coils: Tsis tsuas yog nws tuaj yeem ntsuas tus nqi thauj khoom, qhov nqi xa tawm, thiab lub sijhawm ua haujlwm, tab sis nws kuj tseem tuaj yeem ntsuas qhov "tsawg kawg tuav tus nqi"- los ntawm kev muab qhov hluav taws xob tsis tu ncua rau lub kauj ntawm lub ntsuas qhov tso zis, tom qab ntawd kho qhov tam sim no mus rau qhov tsawg kawg nkaus tus nqi yuav tsum tau tswj tus relay kev koom tes tom qab ua haujlwm.
Sib txawv relays: Siv BCH-1 qauv ua piv txwv, nws tuaj yeem ua qhov kev sim uas yuav tsum tau muaj xws li kev ntsuas ntsuas ntsuas ntsuas, qhov ntsuas hluav taws xob tam sim no, thiab ntsuas tus yam ntxwv braking (yuav tsum muaj cov ntsuas hluav taws xob sab nraud thiab cov boosters tam sim no). Nws kuj tseem txhawb nqa kev ntsuas kev ua tau zoo rau lwm qhov tshwj xeeb sib txawv relay specifications thiab ua kom haum raws li qhov xav tau rau ntau yam tsis yog qauv relays.

2) Lub tshuab ua haujlwm nyuaj npaum li cas? Peb cov neeg ua haujlwm tsuas muaj kev paub txog hluav taws xob yooj yim xwb. Lawv puas xav tau kev cob qhia kev cob qhia kom pib?

Teb:
Cov cuab yeej yog tsim los rau "kev ua haujlwm yooj yim." Cov neeg ua haujlwm uas muaj kev paub txog hluav taws xob yooj yim tuaj yeem paub sai sai yam tsis muaj kev cob qhia. Cov txiaj ntsig tseem ceeb muaj xws li:
Intuitive Vaj Huam Sib Luag: Txhua qhov haujlwm tau pom meej meej. Cov pob qhov tseem ceeb xws li Kev Xaiv Cov Tso Tawm (T1), Kev Kho Kom Zoo Tshaj Tawm (T2), thiab Kev Tiv Thaiv Tus Txheej Txheem Xaiv (T3) muaj cov ntawv sau meej meej. Tiag - lub sij hawm cov lus qhia yog muab los ntawm Current/Voltage Display (X1), Millisecond Timer (X2), thiab Output Type Indicators (ACV/ACA, etc.), tshem tawm qhov xav tau kev txiav txim tshwj xeeb.
Cov Txheej Txheem Tshaj Tawm: Tag nrho cov khoom tso tawm ua raws li peb - cov txheej txheem: "Xaiv ntau yam → Kaw Hloov → Kho qhov loj." Thaum ntsuas qhov tseem ceeb tsis zoo xws li cov nqi xa mus los yog lub sijhawm, cov neeg ua haujlwm tuaj yeem txiav txim siab raws li txoj cai los ntawm kev sib txuas ntawm cov xov hlau hauv phau ntawv qhia thiab saib xyuas lub teeb pom kev ua haujlwm. Kev sib txuas lus ntawm kev hloov txoj haujlwm thiab cov xeev kev sib cuag yog yooj yim thiab nco ntsoov (I / IV Range: "Kaw → Qhib"; II / III Range: "Qhib → Kaw").
Kev Txhawb Nqa: Phau ntawv muab cov kab kos tshwj xeeb (xws li, rau nruab nrab relays, sib txawv relays) thiab cov kauj ruam ua haujlwm rau ntau hom relay. Ua ke nrog intuitive taw qhia tawm tswv yim, cov neeg teb xov tooj tuaj yeem ua tiav kev sim los ntawm kev ua raws li phau ntawv tsis muaj kev txawj ntse ntxiv.

3) Thaum lub sij hawm sim teb, txav cov cuab yeej yuav tsim nyog. Lub cuab yeej tiv thaiv kev puas tsuaj los ntawm kev xaim tsis raug lossis kev ua haujlwm zoo li cas? Puas yog niaj hnub tu complex?

Teb:
Cov cuab yeej suav nrog cov qauv tsim tshwj xeeb rau kev tiv thaiv kev nyab xeeb thiab kev saib xyuas niaj hnub, txo qis kev pheej hmoo ntawm kev siv nrog cov nqi tu tsis tshua muaj:
Kev Tiv Thaiv Kev Nyab Xeeb:
Luv- tiv thaiv Circuit Court: Qhia meej meej txwv tsis pub luv luv ntawm cov khoom siv hluav taws xob thiab nruab nrab ntawm cov chaw sib txuas thiab cov khoom siv hluav taws xob. Internal fuse tuav tau teeb tsa; Nyob rau hauv cov ntaub ntawv ntawm overload los yog luv luv Circuit Court, tsuas yog hloov lub fuse nrog tib tus qauv kom rov ua haujlwm, tiv thaiv kev puas tsuaj rau cov khoom tseem ceeb.
Kev ceeb toom kev nyab xeeb ua haujlwm: Lub hwj chim yuav tsum raug tua thaum txuas lossis txiav cov xov hlau. Cov khoom siv hluav taws xob sab nraud yuav tsum tsis txhob txuas nrog kev sib cuag thaum ntsuas lub sijhawm ua haujlwm, tshem tawm cov kev pheej hmoo ntawm kev nyab xeeb los ntawm cov txheej txheem ua haujlwm.
Kev Ceeb Toom Tshaj Tawm: "Tsis txhob tshaj qhov ntsuas tam sim no" raug cim kom meej meej thaum lub sij hawm DC hloov tam sim no los tiv thaiv kev ntsuas kev puas tsuaj los ntawm kev ua haujlwm tsis raug.
Kev tu txhua hnub:
Tsis muaj kev tu vaj tse complex yuav tsum tau. Tsuas yog xyuas kom 5-10 feeb sov- lub sijhawm ua ntej kev sim (kom lav qhov ntsuas qhov tseeb).
Yog tias cov cuab yeej ua haujlwm tsis zoo, ua ntej tshawb xyuas lub fuse tuav - hloov yuav tsum tsis muaj cov cuab yeej tshwj xeeb. Rau qhov tsis yog - teeb meem fuse, hu ncaj qha rau cov chaw tsim khoom. Tsis txhob sim disassembly lossis kho koj tus kheej. Tus nqi tu qis thiab qhov nyuaj me ntsis.
