Litsietsi tsa tlhahlobo e tobileng ea hajoale (DC)
. Voltage e ekelitsoeng le eona e tlaase hape. Ha palo ea tjhente e kholo haholo, e tla baka ntho e fosahetseng ka tebello mme e etsa hore tlhahlobo ea tlhahlobo e fosahetse.
.
(3) Ho fapana le tlhahlobo ea AC, DC e atisang tlhahlobo ea voltage e ka lekoa feela ka polao e le 'ngoe. Haeba sehlahisoa se lokela ho sebelisoa tlasa voltage ea ac, sekhobo bona bo lokela ho hlahlojoa. Ena hape ke lona lebaka le etsang hore batsamaisi ba polokeho e ngata ba khothaletsa ho sebelisa tlhahlobo ea voltage.
. Ka hona, melaoana e mengata ea polokeho e hloka hore haeba tlhahlobo ea DC e thibela tlhahlobo ea Voltage, ho tlameha ho eketsoa boleng bo lekanang.
Kamora hore tlhahlobo ea DC e hlorisoe, haeba ntho e potlakileng e sa khathatsane, ho bonolo ho baka motlakase; Liteko tsohle tsa rona tsa DC tse hlolang litlhokahalo tsa Voltage li na le ts'ebetso e potlakileng ea 0.2. Kamora hore tlhahlobo ea vC e hlorise e phethetsoe, tebello e ka tlosa motlakase ka boomo ho mmele o lekiloeng ka har'a 0.2s ho sireletsa polokeho ea opereishene.
Kenyelletso ea melemo le likotsi tsa AC Mamela tlhahlobo ea Voltage
Nakong ea tlhahlobo ea Voltage ea Marang-rang For example, the working voltage of a tested object is 220V, when the withstand voltage test is performed, the voltage of the withstand voltage tester is 220V+1000V=1440V, generally 1500V.
Teko ea Voltage ea Marang-rang e arotsoe ka tlhahlobo ea voltage le DC e thibela tlhahlobo ea Voltage; Melemo le likotsi tsa tlhahlobo ea AC Manaha li ka etsahala ka tsela e latelang:
Melemo ea tlhahlobo ea voltage:
(1) Ka kakaretso ho bua, tlhahlobo ea AC e bonolo ho amoheloa ke yuniti ea polokeho ho feta tlhahlobo ea DC. Lebaka le ka sehloohong ke hore lihlahisoa tse ngata tsa lihlahisoa li sebelisa chelete ea hona joale, 'me tlhahlobo e fapaneng ea sehlahisoa e ka leka phepelo e ntle le e mpe ea sehlahisoa ka botlalo, e lumellanang ka botlalo le tikoloho eo sehlahisoa se sebelisoang ka eona le se tsamaisang ka boemo ba tšebeliso ea nnete.
. Teko, ntle le haeba sehlahisoa se tsotella voltage ea inrush e amehang haholo.
(3) Kaha tlhahlobo ea AC e ke ke ea tlatsa lintlha tseo a li sitisang, ha ho na lebaka la ho theola ntho ea tlhahlobo kamora tlhahlobo, e leng monyetla o mong.
Litsietsi tsa Ac Mamela Teko ea Voltage:
. ea hajoale.
. Sena se eketsa kotsi ho opereishene.
Na ho na le phapang lipakeng tsa ho lemoha ha ARC le ho leka hajoale?
1. Mabapi le ts'ebeliso ea ts'ebetso ea arc (arc).
a. ARC ke ntho e 'ngoe ea' mele ea nama, ka kotloloho e le sebaka se phahameng sa li-voltage.
b. Maemo a Production: Tšusumetso ea tikoloho, ts'ebetso ea ts'ebetso, ts'ebetso ea lisebelisoa.
c. ARC e amehile haholo ebile e amehile haholo, 'me hape ke e' ngoe ea maemo a bohlokoa a ho lekanya boleng ba sehlahisoa.
d. Setsebi sa RK99 se laoloang ke lenaneo la RK99 se Hlokahalang Lisa mehlala ea Fly-Fly-Fly-Fly-Fly-Fretal ka holimo ho 10khz ka pina e phahameng ka holimo ho 10kzz, ebe u tšoaneleha ho tseba hore na e tšoaneleha. Foromo ea hajoale e ka beoa, 'me foromo ea boemo bo holimo le eona e ka beoa.
e. Mokhoa oa ho khetha boemo ba kutlo bo lokela ho beoa ke mosebelisi ho latela litšobotsi le litlhokahalo tsa sehlahisoa.
