The kushanda musimboti chakanamwa nomoto inverter: tsananguro, matunhu namano

Traditional nomoto michina pamwe chete transformers hombe dziri zvishoma kupera. Asi, zvino pane tsindirana nomoto inverters. Ndivo nyore kushandisa, vanogona kunyange kushandiswa kutanga. Kuti uzive kworudzii mudziyo, zvakafanira kufunga marongerwo uye kushanda nheyo chakanamwa nomoto inverter.

About patani

The mudziyo yakasiyana zvetsika uye Kunyatsoziva mumwe ndiri weredha transformers. The inverter kushanda ano kutendeutsa pezvakaitwa kuitika kudaro. azvaiitwa kuitika mumatanho aine transformer duku, ane kukura zvishoma hombe packs it yefodya. Mumwe musiyano - wemagetsi kudzora hurongwa. Kunoitawo kuti aivabatsira chakanamwa nomoto rikurumidze. Nemhaka mae-unhu majoini akaumba hurongwa. Heunoi sei inverter nomoto muchina. Reviews zvokushandisa iri kupfuura zvakanaka. Vanhu vakawanda vanoshandisa nokuda tsindirana zvakagadzirwa uye weld unhu.

Zvinonyatsorehwa musimboti kushanda

Pakutanga, chiyamuro dzenzvimbo ane voltage pamusoro 220 volts panguva shanduka maitikiro runoyerera napakati rectifier uye kutendeuka kuva dzose. Uyezve, magetsi paanenge ndokudzora pedyo firita. Kazhinji, rinoshandiswa sechiratidzo chetsika zano yakavakirwa electrolytic capacitors. Next, DC voltage uye ano kupfuura achishandisa semiconductor modulator, apo zvakare vatendeukira AC, asi pamwe dzakakwirira frequencies. In siyana yokutevedzera, mufananidzo uyu akasiyana, asi asingaiti pfuura 100 kHz. Magetsi paanenge ipapo kunogadzirisika uye voltage zvakare anosiya kukosha zvinodiwa weld simbi. The uchishandisa nheyo inverter nomoto yakavakirwa kumusoro-maitikiro converters. Kuvapo yenhengo izvi zvinobvumira kushandiswa transformers duku, nokudaro akaderedza zvikuru chikwata uremu. Somuenzaniso, kuti inverter nomoto muchina kukwanisa kupa kwazvino 160 amperes, kuti transformer unofanira kuyera anopfuura 250 magiramu. transformer vaizova risingamboshandisi kurema makirogiramu 18 kuita zvakafanana mugumisiro vachishandisa kwakajairika midziyo. Zvakavaomera zvikuru.

Kudzorwa chikwata - huru mukana inverter nomoto michina

A basa rinokosha mukushanda zvokushandisa ichi anotamba Electronics. Nokuda narwo Ivan Kuchin ukama. Izvi zvinobatsira kudzora zvizere chinhu chakakombama, kuchinja kana kuti kuiita nenguva yakafanira pamwero kana zvakakodzera. The kuchangotanga kutsauka chinhu chakakombama unhu pakarepo kuverengwa microprocessor. Pfungwa dzakadaro kushanda ari inverter nomoto muchina uye kuva wemagetsi kudzora chikwata kupa yemagetsi chinhu chakakombama kunonyanyisa akatsiga maitiro. Izvi pakupedzisira anowedzera unhu chakanamwa nomoto.

schematic dhayagiramu

Muna rectifier rakatumbuka razvino ari kakawanda 50 Hz uye voltage vana 220 volts inopfuura kuburikidza diode zambuko simba. Ripple anoshandiswa shanduka maitikiro ndokudzora nemhaka pamberi iri kutenderera electrolytic capacitors. In mashandiro, kuti diode zambuko iri pasi overheating, saka diodes vakatasva radiators. Mukuwedzera, inverter iri nepokuongorora chafariz fiyuzi. Iye akaparirwa kana diodes vakanga neshungu kuti madhigirii 90. Thermal chinodzivirira diodes. Next kuti diode zambuko anogona kuonekwa zvakarurama simba uchitikurudzira capacitors. Kukwanisa kwavo ingabva 140 kusvika 800 microfarads. Uyewo ari mudunhu vanogara varipo filters, izvo murege ari mubishi upi chipingaidzo. Takurukura chii ane nomoto inverter musimboti. Driving zvinoreva ndemamwe zvinhu. Ngationgororei navo pasi.

Inverter: chii

Zvakananga inverter pachayo yakavakirwa zviviri mosfetah. simba iri transistors. Avanotarisira kuti ripise kwazvo, saka vakagadzirira pamwe redhiyeta. Kwakadaro semiconductor zvinhu kupedza dambudziko Nokuchinja kubva dzenzvimbo nomunyika kufamba kweropa transformer. Kushanda frequencies pano anogona pfuura zviuru zvakawanda kHz. Somugumisiro ichi kuitika ari vanowanika ane shanduka maitikiro. The transistors kunge husingakwanisi voltage madonhwe. Manufacturers ngaakushongedzei mudziyo pamwe matunhu unodzivirira inokosha. Kazhinji, vachazowana kuburikidza redunhu resistors uye capacitors. Zvadaro unosvika yechipiri ichitenderera kusvika danho-pasi transformer. Her voltage duku - 70 volts. Asi iyezvino unogona kuva 130-140 Amps.

The goho rectifier

Kuti pave kuramba goho kuitika uye voltage rinoshandisirwa yakavimbika goho rectifiers. zano iri kuitika nemhaka miviri diodes, vane zvakafanana cathode. zvinhu izvi zvinhu mukuru-waivako, vakabva akazarurwa uye yakavharwa nokukurumidza. The zvakaitwa nguva diodes iri vanenge 50 nanoseconds. Kasira Izvi zvakakosha kwazvo. Diodes kushanda pamwe dzenzvimbo dzakakwirira kakawanda, vanhuwo semiconductor zvinhu havagoni kurarama rakadai. Vakanga havambokwanisi zvakakwana nokuchinja nokukurumidza. Kana kugadziriswa, kunyange kuziva nomoto inverter mudziyo, kuti uchishandisa pfungwa, diodes aya varumbidzwa kuchinja kuti zvinhu pamwe chete unhu.

Design uye nokushanda wemagetsi hurongwa

Zvinonzi dzinofambiswa nokuda voltage regulator, rakagadzirirwa 15 volts. zvinhu izvi zviri kuiswa pamusoro radiators. Supply voltage nokuti bhodhi zvinobva huru rectifier. Kana voltage parinoshandiswa, kutanga mhosva capacitors. The voltage panguva ino ari kukura. Kudzivirira diode gungano akashandisa zvinhu zano nesimba resistors. Kana capacitor zvizere mhosva, chakanamwa nomoto muchina uchatanga basa rayo. Kuvhara ataure neshamwari, uye resistor haangazozikamwi muzvirongwa izvi.

Zvimwe zvinoriumba uye nehurongwa

Chimiro uye kushanda nheyo chakanamwa nomoto inverter inotaura nokuvapo dzimwe gadziriro uye zvinoriumba izvo zvinopa yakadaro yakakwirira mudziyo unongotaura. Saka, unogona kusarudza kudzora gadziriro, uyewo vatyairi. The chikuru chaikosha pano ari PWM controller chip. Inopa kudzora zviito simba transistors. Uyewo, mudziyo ane siyana kudzoreka uye murau redunhu. Panyaya iyi, chikuru chinhu ari transformer. Zvakakodzera kudzora simba uye mamwe maitiro magetsi mushure goho transformer. Zviito Welding inverter nheyo kunorevawo kuvapo marongedzero vachiongorora zviri voltage uye mamiriro zvechadenga goho pakati mains rive. chikwata ichi chine ane nematunhu gudzazwi nemabhuku operative. Chinangwa chikuru wegadziriro - kutanga zvashata kudzivirira muoti pakuparwa zvashata. Zvinonzi zvakare zvakagadzirirwa kuongorora kuita uye serviceability pakati electronic chikwata.

Welding michina nokuti TIG Welding pamwe argon

simbi inert gasi nomoto - zviri chimwe chezvinhu dzakakurumbira nzira Chinyorwa nomoto nhasi. Basa pamwe argon inopa yepamusoro majoini yakafanira kuti apedzise voga pakati nokushambidza. Saka zvinoita kushanda nesimbi zvose, kunyange aruminiyamu, magnesium, titanium dzavo alloys. Nheyo inverter nomoto pamwe argon chinhu chinokosha kubva zvake inverter haisi zvakasiyana. Musiyano chikuru ndechokuti kwete chete akashandisa Welding simba panobva, asiwo chaiyo burner kwacho. TIG-nomoto kunosanganisira kudziyisa pamusoro zvachose kushanda muchikamu pachishandiswa wemagetsi chinhu chakakombama izvo zvakasikwa pachishandiswa refractory tungsten electrode. Vazhinji dzinonakidza kuona sei inverter nomoto muchina kwakadai. Ngationei.

Construction nomoto TIG-mudziyo

An midziyo nokuti TIG nomoto uri kuitika tsime uye rinokosha burner. Origin runodikanwa generating wemagetsi chinhu chakakombama, uye kuramba yaro yakawanda iri kwomuzvarirwo parameters. A kuwanda nesimbi uye alloys, izvo zvinogona kushanda nenzira, imwe muzvizhinji kuti kuchinja zvinoreva. Nhasi rinoshandiswa kuti semiconductor inverter dzakabatana. Izvi nomoto inverter TIG. Nheyo kushanda haana kumbosiyana kubva kwakajairika inverter, asi goho kuti mudziyo yakadaro vasanganiswa. Direct razvino rinoshandiswa kushanda Stainless simbi, alloys mhangura. Shanduka uyewo yakanakira magnesium, aruminiyamu nezvimwe alloys zvakafanana. mashandiro kana inoratidza dzenzvimbo akashandiswa Welding matete nhengo. Uyewo ari burner mamiriro yazvinofanira. Chii? Iri zano rinokosha iro yakatarwa tungsten electrode. It ane kamwene kuburikidza iyo argon rive. Kusiyana nezvaiitwa nomoto semiautomatic, mumwe TIG nomoto romoto kuti gasi wedzerai avamba pamberi vesa kuti chinhu chakakombama. Izvi haambotauri unopfuta simbi.
