Puas yog cov khoom siv rwb thaiv tsev ntawm lub cev muaj zog txiav txim siab los ntawm qhov loj ntawm qhov tam sim no lossis qhov voltage?

Yog lub rwb thaiv tsevkhoomntawm lub cev muaj zog txiav txim los ntawm qhov loj ntawm qhov tam sim no lossis qhov voltage?

Cov khoom siv rwb thaiv tsevyog ib qho tseem ceeb ntawm cov khoom siv lub cev muaj zog. Cov motors uas muaj qhov sib txawv ntawm qhov sib txawv muaj qhov sib txawv ntawm cov qauv rwb thaiv tsev ntawm lawv cov windings thiab lawv cov khoom tseem ceeb. Piv txwv li, lub rwb thaiv tsev qauv ntawm high-voltage motor thiab low-voltage motor windings yog txawv heev. .

Cov ntaub ntawv insulating, tseem hu ua dielectrics, yog cov khoom uas muaj siab tiv taus thiab tsis zoo conductivity. Lawv kuj tseem siv rau hauv cov khoom siv lub cev vim lawv cov conductivity tsis zoo. Hauv cov khoom siv lub cev, los ntawm cov ntaub ntawv insulating, ntawm ib sab, cov xov hlau conductive txuas nrog lwm cov khoom. Kev sib cais, ntawm qhov tod tes, yog cais cov ntsiab lus sib txawv ntawm cov kab hluav taws xob, xws li kev cuam tshuam kev cuam tshuam thiab kev cuam tshuam ntawm cov txheej txheem. Cov ntaub ntawv insulating sib txawv kuj tuaj yeem muaj ntau yam khoom xws li kev txhawb nqa, kho, arc extinguishing, mildew kuj, hluav taws xob tiv thaiv thiab corrosion kuj.

Kev kub hnyiab ntawm lub cev muaj zog windings yog ib qho kev tshwm sim ntawm kev puas tsuaj los yog ploj ntawm kev ua haujlwm rwb thaiv tsev. Tom qab ntawd, puas yog lub rwb thaiv tsev kev ua tau zoo ntawm lub cev muaj zog degraded vim qhov loj winding tam sim no los yog high voltage?

When the motor winding current is too large, the higher current density will cause the winding resistance to increase and cause serious heat generation. The heat generated by the motor will be dissipated through the insulation. When the heat reaches a certain level, the structure of the insulating material will undergo qualitative changes, such as the motor The performance requirements of different insulation grades such as B, F, and H involved in the table correspond to the maximum working temperature that the cov khoom siv insulatingtuaj yeem tiv taus.

Rau lub cev muaj zog winding, lub rwb thaiv tsev yuav tsum tau nruab nrab ntawm kev tig thiab tig, ntawm qhov sib txawv ntawm ntau theem ntawm lub cev muaj zog, thiab nruab nrab ntawm tus neeg xyuas pib thiab hauv av tau koom nrog. Thaum lub ntsuas hluav taws xob ntawm lub cev muaj zog siab dua, qhov hluav taws xob ntawm lub rwb thaiv tsev winding kuj siab dua, uas tuaj yeem yooj yim xav txog qhov no raws li cov khoom sib txawv. Yog hais tias qhov voltage ntawm lub capacitors siab dhau lawm, nws yuav ua rau muaj teeb meem ntawm lub capacitor breakdown, uas yog, lub rwb thaiv tsev tsis ua hauj lwm ntawm lub cev muaj zog winding mus rau hauv av, ntawm lem thiab ntawm theem.

Los ntawm cov ntsiab lus saum toj no, peb tuaj yeem nkag siab tias txawm hais tias tam sim no ntawm lub tshuab hluav taws xob high-voltage me me, qhov hluav taws xob rwb thaiv tsev ntawm cov windings yog siab, yog li cov txheej txheem rwb thaiv tsev tshwj xeeb yuav tsum tau siv los xyuas kom meej tias cov hluav taws xob ua tau zoo ntawm lub cev muaj zog ua tau raws li qhov yuav tsum tau ua. ; Thaum lub tshuab hluav taws xob tsis tshua muaj hluav taws xob, vim tias qhov hluav taws xob rwb thaiv tsev yog qhov siab heev Yog li ntawd, kev xaiv cov ntaub ntawv insulating yog qhov yooj yim, tab sis tam sim no qhov ntom ntom, qhov cua thiab cua kub dissipation yog qhov tseem ceeb los xyuas kom meej qhov hluav taws xob ua haujlwm ntawm lub cev muaj zog. Tam sim no thiab voltage ntawm lub cev muaj zog muaj kev cuam tshuam sib txawv ntawm qhovcov khoom siv insulatingthiab yuav tsum tau coj mus rau hauv tus account tib lub sijhawm.
