Kev daws rau Inverter Overload Faults

Inverteroverload faults feem ntau manifest raws li ib tug sustained tso zis tam sim no tshaj tus nqi ntsuas. Qhov teeb meem tseem ceeb yog qhov tsis sib haum xeeb ntawm qhov kev xav tau ntawm lub tshuab hluav taws xob (lossis lub cev muaj zog) tso zis muaj peev xwm.

Kauj Ruam 1: Kev soj ntsuam tam sim ntawd thiab pib tuav

1. Fais fab-tawm pib dua:Thaum ua kom muaj kev nyab xeeb, sim txiav lub inverter los ntawm lub hwj chim mov, tos ob peb feeb, thiab rov txuas nws. Qee zaum qhov no yuav yog vim muaj kev cuam tshuam ib ntus lossis lub tswb tsis raug.

2. Sau Cov Lus Qhia Tseem Ceeb:Sau cov cai txhaum cai, kev khiav hauj lwm zaus thaum lub sij hawm tshwm sim, tam sim no, thiab lub load tej yam kev mob.

3. Txheeb xyuas cov xwm txheej Load:Tshawb xyuas cov khoom siv hluav taws xob txuas nrog lub cev muaj zog, xyuas seb qhov hnyav hnyav lossis jamming.

Xyuas cov cuab yeej siv tshuab rau kev thaiv, hnav, lubrication tsis txaus, cov kabmob puas, lossis lwm yam teeb meem.

4. Tsis muaj -load Run Test:Disconnect lub cev muaj zog los ntawm lub load mechanically, cia nws mus nyob twj ywm, thiab khiav lub inverter, maj mam nce qhov zaus.

Yog hais tias tsis muaj - load mob kuj yog overloaded: Qhov teeb meem nyob nrog lub cev muaj zog, cables, los yog lub inverter nws tus kheej.

Yog tias tsis muaj -load mob yog ib txwm: Qhov teeb meem yog nyob rau sab load lossis hauv cov khoom sib kis ntawm cov tshuab.

 

Kauj Ruam 2: Hauv - tshawb xyuas qhov tob rau kev ua haujlwm tsis muaj -load

Yog tias tsis muaj - kev ua haujlwm thauj khoom yog qhov qub, tab sis overload tshwm sim nyob rau hauv load, nws qhia tau hais tias lub inverter lub peev xwm tsav yog txaus, tab sis lub load yog hnyav heev.

1. Tshawb xyuas cov tshuab kis tau tus mob:

Bearings: Xyuas seb cov bearings ntawm lub cev muaj zog thiab lub tshuab thauj khoom tsis muaj lubrication, puas, lossis raug ntes.

Kev sib txuas mechanism: xyuas seb txoj siv tawv nruj dhau, plam, lossis puas; yog hais tias lub gearbox tsis muaj lubrication los yog hnav; yog hais tias lub coupling yog misaligned.

Qhia rails/slides: Xyuas seb puas muaj kev cuam tshuam los yog lubrication tsis txaus.

2. Txheeb xyuas qhov load nws tus kheej:

Overload: Piv txwv li, yog cov khoom thauj khoom hnyav dhau los yog pawg; yog cov twj tso kua mis qhib dav dhau, ua rau cov dej ntws mus deb tshaj qhov tsim; Cov kiv cua dampers puas txawv txav?

Cov txheej txheem hloov pauv: Puas yog cov txheej txheem yuav tsum tau hloov pauv, ua rau muaj kev nce ntxiv hauv kev thauj khoom?

3. Tshawb xyuas lub cev lub cev:

Rwb thaiv tsev: Siv lub megohmmeter los ntsuas cov rwb thaiv tsev tiv thaiv ntawm lub cev muaj zog windings mus rau hauv av, xyuas seb cov dej noo los yog kev laus puas ua rau cov rwb thaiv tsev txo qis, ua rau muaj zog tam sim no.

 

Kauj ruam 3: Nyob rau hauv - qhov tob daws teeb meem rau Tsis muaj -Load thiab overload teeb meem

1. Tshawb xyuas lub cev muaj zog thiab Cables:

Cables: Tshawb xyuas lub cav fais fab cable rau kev puas tsuaj, kev laus, thiab xoob lossis oxidized terminals.

Lub cev muaj zog: Ntsuas qhov DC tsis kam ntawm lub cev muaj zog windings thiab xyuas peb -theem imbalance. Kev tsis txaus siab hnyav qhia tau hais tias muaj kev cuam tshuam hauv lub cev muaj zog.

2. Xyuas thiab optimize Inverter Parameters:

Lub cev muaj zog Parameter Tus Kheej-Tuning: Muab cov ntaub ntawv npe lub cev muaj zog rau hauv lub inverter thiab ua qhov zoo li qub lossis dynamic tus kheej-tuning. Qhov no zoo heev txhim kho kev tswj kev ua haujlwm thiab zam dhau overcurrent tshwm sim los ntawm qhov tsis raug.

Acceleration/Deceleration Time: Yog hais tias lub sij hawm acceleration yog luv heev, qhov pib tam sim no yuav siab dhau, yooj yim ua rau overload. Tsim nyog ncua lub sij hawm acceleration.

Overload Protection Factor: Tshawb xyuas seb lub cev muaj zog tiv thaiv kev tiv thaiv lossis kev txwv tam sim no ntawm lub inverter puas tsim nyog.

3. Txheeb xyuas Inverter thiab lub cev muaj zog xaiv:

Fais fab sib piv: Lub zog inverter yuav tsum siab dua los yog sib npaug ntawm lub cev muaj zog. Rau qhov hnyav - load pib thiab cuam tshuam rau lub sijhawm, yuav tsum xaiv qhov siab dua - lub zog inverter (ib lossis ob qhov nrawm) yuav tsum tau xaiv.

Kev sib piv tam sim no: xyuas kom meej tias qhov ntsuas qhov tso zis tam sim no ntawm lub tshuab hloov zaus ntau dua li qhov ntsuas tam sim no ntawm lub cev muaj zog.
