Puas yog servo tsav board muaj overcurrent, overvoltage, thiab overheat tiv thaiv?

Servo tsav boards feem ntau muaj overflow, overpressure thiab overheating tiv thaiv. Cov txheej txheem tiv thaiv no yog cov haujlwm tseem ceeb tsim los ua kom muaj kev nyab xeeb thiab ruaj khov ntawm lub servo system. Kev tsom xam tshwj xeeb yog raws li hauv qab no:

1.Overcurrent Protection: tiv thaiv cov cuab yeej los ntawm kev puas tsuaj los ntawm cov khoom siv tam sim no.
Muaj nuj nqi: Thaum lub cev muaj zog ua haujlwm tam sim no tshaj qhov kev nyab xeeb ntawm tus neeg tsav tsheb, kev tiv thaiv overcurrent yuav tshwm sim tam sim ntawd, txiav tawm lub hwj chim lossis txwv cov zis tam sim no los tiv thaiv lub cev muaj zog, cable lossis tsav lub rooj tsav xwm los ntawm kev kub dhau.
Tawg Scenario:
Sudden load hloov (xws li, mechanical jamming, impact).
Luv -circuit lossis winding grounding txhaum ntawm lub cev muaj zog.
Cov khoom siv hluav taws xob sab hauv (xws li IGBTs) ntawm lub rooj tsavxwm tau raug puas tsuaj.
Piv txwv li, nyob rau hauv kev txhaj tshuaj molding tshuab, lub hardening ntawm kev taw qhia rail lubricating roj muaj zog kev sib txhuam coefficient, uas ua rau ib tug tam sim ntawd nce ntawm lub cev muaj zog tam sim no. Qhov no ua rau muaj kev tiv thaiv overcurrent, nres lub tshuab thiab tiv thaiv kev puas tsuaj ntxiv.

2.Overvoltage Kev Tiv Thaiv: Kev cuam tshuam nrog qhov txawv txav ntawm qhov voltage.
Kev Ua Haujlwm: Thaum cov khoom siv hluav taws xob ntau tshaj qhov ntsuas hluav taws xob ntau ntawm lub rooj tsav xwm tsav tsheb (xws li 460V hauv 400V system), kev tiv thaiv overvoltage yog qhib kom tiv thaiv cov khoom siv hluav taws xob los ntawm kev puas tsuaj los ntawm overvoltage.
Qhov teeb meem tshwm sim: Instant voltage surges ((piv txwv li, xob laim, kev hloov pauv ntawm lub zog hluav taws xob tam sim ntawd.
Regenerative braking zog tsis dissipated nyob rau hauv lub sij hawm (rov qab voltage ua thaum lub sij hawm lub cev muaj zog deceleration).
Txoj kev daws teeb meem: Siv lub zog tiv thaiv sab nraud kom hlawv tawm lub zog ntau dhau.
Pab kom dynamic braking kom ncua sij hawm deceleration.
Configure lub zog tawm tswv yim units (xws li, siab inertial load mob).
Cov ntaub ntawv kawm: Ib qho Delta servo tsav ua rau muaj kev tiv thaiv overvoltage vim qhov hloov pauv ntawm qhov hluav taws xob hauv kab hluav taws xob; Qhov teeb meem no tau daws los ntawm kev txhim kho voltage regulator.

3. Kev tiv thaiv overheat: tiv thaiv kev ua haujlwm tsis zoo lossis kev puas tsuaj los ntawm qhov kub thiab txias.
Muaj nuj nqi: siv qhov ntsuas kub ntsuas los saib xyuas qhov kub ntawm lub phaj tsav lossis lub cev muaj zog hauv lub sijhawm. Thaum qhov kub siab tshaj qhov ceeb toom tus nqi (xws li . 85℃rau IGBT modules thiab 65℃rau cov dab dej kub), nws cia li kaw los yog ua haujlwm ntawm qhov kub thiab txias.
Cov xwm txheej tshwm sim: cua txias kiv cua tsis ua hauj lwm los yog cua ducts blockage.
Siab kub ambient kub los yog cov cuab yeej txuas ntxiv mus khiav ntawm kev thauj khoom siab.
Kev laus ntawm thermal roj ua rau txo qis thermal conductivity.
Cov Lus Qhia Txog Kev Kho: Ntxuav lub dab dej kub tsis tu ncua (txhua 2000 teev).
Hloov cov kua nplaum kub (Shin-Etsu X-23-7762 pom zoo).
Qhov ntsuas kub ntawm lub zog fais fab module tau kuaj xyuas siv lub tshuab hluav taws xob infrared thermal.
Cov ntaub ntawv kawm: Tus neeg tsav tsheb servo overheated vim muaj plua plav nyob rau hauv nws cov heatsink. Nws raug ntxuav thiab rov qab mus ua haujlwm li qub.
