Scope ntawm daim ntawv thov

Ntxiv rau qhov txhaum tam sim no hauv AC thiab mem tes tam sim no ntau yam, hom B tseem kuaj pom DC qhov tsis raug tam sim no, uas tuaj yeem tshwm sim hauv kev tswj hwm zaus inverter, cov tshuab hluav taws xob photovoltaic nrog rau kev siv hluav taws xob hauv tsev neeg, thiab ua kom muaj kev nyab xeeb ntau ntxiv.

Daim ntawv thov nrog

● Cov ntawv thov nrog:

.Cov khoom siv thiab lub cev muaj zog nrog 1Phase zaus converters nrog PFC ([Power factor them) lossis .1 theem zaus converters muab ntawm theem / theem lossis .3 theem zaus converters

.DC systems (photovoltaic systems, ups units..)

.Nyob rau hauv pem hauv ntej ntawm PV Systems / roj teeb lub tsev txhab nyiaj / UPS units / EV them kho mob pab kiag li lawm / zaus converters / lub cev muaj zog controllers

.rhiab heev rau tag nrho cov seem tam sim no raws li lkHz.

Residual Devices Tam sim no-Cov ntaub ntawv dav dav

Cov lus piav qhia luv luv ntawm hom RCD tseem ceeb tshaj plaws:

Symbol Description

HONI txuj.Haum rau kev teeb tsa sab nraum zoov (cov thawv ntim khoom rau sab nraum zoov kev teeb tsa thiab lub tsev qhov chaw +-25 txog -25 ℃ .

Hom AC: AC tam sim no rhiab heev RCCB

Hom A: AC thiab pulsating DC tam sim no rhiab RCCB

Kev mus ncig kuj tseem muaj nyob ntawm zaus (10 Hz, 50 Hz, 1000 Hz)

Hom B: Tag nrho cov tam sim no rhiab RCD switchgear rau daim ntawv thov qhov twg DC txhaum tam sim no yuav tshwm sim.Non-xaiv tsis ncua.Kev tiv thaiv tawm tsam txhua yam kev txhaum tam sim no.
