Dab tsi yog lub luag haujlwm thiab lub hauv paus ntsiab lus ntawm kev hloov pauv-zaus tsav?

Qhov sib txawv-frequency drive (VFD) yog lub tshuab hluav taws xob tswj hluav taws xob uas siv cov cuab yeej hloov pauv zaus thiab microelectronics thev naus laus zis los tswj lub rooj tsav xwm AC motors los ntawm kev hloov cov zaus ntawm lub cev muaj zog ua haujlwm.

Lub inverter yog tsim los ntawm rectification (AC rau DC), filtering, inversion (DC rau AC), braking unit, tsav unit, nrhiav kom tau unit, microprocessor unit, thiab lwm yam. sab hauv IGBT qhov kev txiav tawm, thiab muab cov khoom siv hluav taws xob xav tau raws li qhov xav tau tiag tiag ntawm lub cev muaj zog, yog li ua tiav lub hom phiaj ntawm kev txuag hluav taws xob thiab kev tswj ceev. Tsis tas li ntawd, lub inverter muaj ntau yam kev tiv thaiv kev ua haujlwm, xws li overcurrent, overvoltage, overload tiv thaiv, thiab lwm yam. Nrog rau kev txhim kho tas mus li ntawm cov degree ntawm industrial automation, inverters kuj tau siv dav.

Kev siv thiab parameter hloov ntawm lub inverter koom nrog ntau yam:

· Pib thiab nres tswj: pib thiab nres lub cev muaj zog los ntawm kev tswj sab nraud los yog cov vaj huam sib luag built-in.

· Kev tswj ceev: hloov qhov ceev ntawm lub cev muaj zog los ntawm kev kho qhov zaus ntawm cov zis fais fab mov.

· Kev tiv thaiv muaj nuj nqi: suav nrog overcurrent, overvoltage, overload tiv thaiv, thiab lwm yam, los tiv thaiv lub cev muaj zog thiab inverter los ntawm kev puas tsuaj.
· Siv ua ke nrog cov tswj xws li PLC: paub txog kev tswj tsis siv neeg thiab txhim kho qib ntawm cov khoom siv automation.

Cov haujlwm ntawm zaus converters yog dav, suav nrog:

· Kev txuag hluav taws xob: txo lub zog pov tseg los ntawm kev kho lub cev muaj zog, tshwj xeeb tshaj yog nyob rau hauv cov khoom siv xws li kiv cua thiab cov twj tso kua dej.

· Txhim kho cov khoom zoo thiab kev ua haujlwm zoo: txhim kho cov khoom zoo thiab kev ua haujlwm zoo los ntawm kev tswj xyuas lub cev muaj zog ceev.

· Txo qhov cuam tshuam ntawm daim phiaj hluav taws xob: txo qhov cuam tshuam rau daim phiaj hluav taws xob los ntawm kev ua kom lub zog hluav taws xob thiab cov nthwv dej tam sim no.

· Txhim kho lub neej kev pab cuam ntawm cov khoom siv: txuas ntxiv lub neej kev pab cuam ntawm lub cev muaj zog thiab lwm yam khoom siv los ntawm kev txo cov neeg kho tshuab hnav thiab hluav taws xob kev ntxhov siab.
