Kutumira tekinoroji ye high-frequency induction heat equipment

Kutumwa kwe high-frequency induction heat equipment

Zvakajairwa zvinofanirwa kunge zvakajairwa usati washandisa Tarisa inverter nekutevera anotevera matanho:

① ingovhara magetsi echikamu chekutonga (chinyorwa: usavhare iyo huru yemhepo switch yedunhu guru), dzvanya gonhi rekabati.

Inverse yekutanga bhatani (girini bhatani), gadzirisa simba rekugadzirisa knob wachi kuenda kune yakanyanya chinzvimbo, uye tarisa neaviri-mitsara oscilloscope kana chiratidzo chedhiraivha chiri padanda rekutonga reimwe IGBT module yakajairika (pulse ingangoita 50% square wave, pulse width

Kumusoro kunosvika + 15V, recess inenge-8V. Mitsetse inokwira nekudzika iri mukati me1 μS, ruoko rwebhiriji ruviri kumusoro nekudzika.

Nzvimbo yakafa yeIGBT gedhi pulses yakakura kupfuura 2 Μs) uye inosimbisa kuti IGBT dhiraivha yeruoko rwebhiriji rimwe chete isophase (iyo zvikanganiso zvekumusoro nezasi hazvifanirwe kudarika 0.5 Μs) uye IGBT drive chiratidzo chepamusoro nepasi. mazambuko maoko anofanira kudzoserwa kumashure.

Kuongorora kwe ② kugadzirisa kupisa. Dhinda bhatani rekutanga, magedhi matatu eSCR anofanira kunge aine pulse ine amplitude yakakura kupfuura 1.8V, upamhi hwehupamhi uye huwandu hwekurovera kweanenge 10kHz.

③ pressure resistance test.Vhara dunhu guru remhepo switch (usavhare control voltage switch) Panguva ino, ona DC voltmeter pointer iri kusimuka zvishoma nezvishoma kusvika kupfuura 500V, tarisa kana midziyo yakajairika (hapana ruzha rusina kujairika, hapana hwema, uye hapana kuparara kwechishandiso), gara kurudyi kwemaminetsi gumi, zvinoenderana nemidziyo yakajairika, switch huru yemagetsi inogona kudzimwa. Panguva ino iyo DC

Dzvinyiriro yacho inodzika zvishoma nezvishoma kusvika zero.

④ yakakwirira frequency induction yekudziya michina, tevera anotevera matanho ekutanga inverter.

Batanidza mvura inotonhorera uye tarisa kana mugero wega wega wemvura inotonhorera wakajairika. Rongedza iyo counterclockwise yesimba rekugadzirisa knob kune diki chinzvimbo, vhara pombi switch, control power switch uye main power switch, Cherechedza kana DC voltmeter ichikwira kusvika kuda kusvika 500V ne kubaya. ikozvino mukushanda kwakajairika.Vashandi vanotumirwa nemugadziri wemidziyo kuti vagadzirise kukosha kwega kwega kwedziviriro kune kukosha kunodiwa (midziyo yakagadziridzwa zvakanyanya isati yabva mufekitari, uye inogona kugadziridzwa zvakakodzera maererano nenzvimbo).

Tsanangudzo ye ⑤ motherboard potentiometer

P1—— inoisa chirauro chepakati chazvino waveform padyo neine wave uye inosiya anenge mazana maviri emakona.

P2– inogadzirisa iyo yepakati frequency ikozvino tora kukosha kwehukuru.

P3—— FM yazvino tora kukosha kwehukuru.

P8– inogadzirisa yepakati frequency yekudzivirira kukosha saizi.

P9—— FM yazvino kukosha kukosha saizi.

P10—— Frequency Table calibration.

⑥ Shudown mumatanho anotevera.

Tanga wagadzirisa knob yemagetsi counterclockwise kusvika padiki position, dzvanya reverse stop bhatani, womisa iri medium frequency sound nekukasika.Dzima main power switch, tarisa DC voltage mita inodonha kusvika zero, wozodzima control power supply switch. uye pombi yemvura

Chinja.

Tsanangudzo yeiyo main control panel chiratidzo chiratidzo chemwenje che ⑦ high-frequency induction heat equipment:

Tsananguro yeiyo yekunze chengetedzo pani chiratidzo chiratidzo mwenje:

⑨ yambiro: Mushure mekunge simba guru rekushandura ravharwa kana kudzorerwa shure, zvinorambidzwa kuedza chero chikamu ne oscilloscope kana tafura, zvikasadaro kukundikana kuchaitika nekuda kwekusvika kwezviyero kunze kwekuedzwa kwechiridzwa.
