Chiyambi cha ntchito ndi makhalidwe a intermediate frequency ng’anjo control panel

A pachimake chowonjezera cha control panel madzi intermediate frequency ng’anjo. Gulu lowongolera magetsi lapakati pafupipafupi limapangidwa makamaka ndi magetsi, owongolera, owongolera, owongolera gawo, gawo loyang’anira chitetezo, dera loyambira mawerengedwe, kutsata ma frequency a inverter, mapangidwe amtundu wa inverter, pulse amplification ndi pulse transformer. Zigawo zake zazikuluzikulu zimagwiritsa ntchito mabwalo ophatikizika a DLJ, osasunthika kwambiri, odzipereka kwambiri. Otsatira awiri otsatirawa adzabwera kukuuzani za ntchito ndi makhalidwe a wapakatikati pafupipafupi ng’anjo ulamuliro gulu.

Chimodzi, ntchito ya intermediate frequency ng’anjo control panel

1. Kugwiritsiridwa ntchito kwa gawo lodzipatulira komanso lapadera kwambiri lophatikizana lanzeru lapakati pa ng’anjo yamoto silingangowonjezera kusinthasintha ndi luntha la dongosolo, komanso kuonetsetsa kukhazikika kwa dongosolo. Ambiri mwama board anzeru am’mbuyomu adagwiritsa ntchito zida zotha kulembedwanso, monga single-chip, makina a PLC, ndipo chifukwa cholemberanso izi, zomwe zili pamapulogalamuwa zitha kuwonongeka m’malo osokonekera kwambiri amagetsi ndi kutentha kwapakati pafupipafupi.

2. Kugunda kwa mtima kumasinthidwa zokha. Kugunda kwa inverter kumatenga kugunda kosinthika, ndipo m’lifupi mwake kumasinthidwa malinga ndi magwiridwe antchito osiyanasiyana a ng’anjo yapakatikati kuti ateteze inverter pulse transformer kuti isalowe mu sub-saturation state. Mphepete mwazomwe zimatuluka zimakhala zotsetsereka, ndipo mawonekedwe a mafundewa ndi osasinthika.

3, kusinthasintha kwapawiri kwa masitima apamtunda. Kukonzanso kwa ng’anjo yapakati pafupipafupi kumatengera kusinthasintha kwapamtunda kwapawiri, zomwe sizimangotsimikizira kudalirika kwa choyambitsa, komanso kumachepetsa kugwiritsa ntchito mphamvu ya choyambitsa ndikuwongolera kukhazikika kwa bolodi.

4. The wapakatikati pafupipafupi ng’anjo ulamuliro gulu ali zosunthika amphamvu ndi oyenera kulamulira zosiyanasiyana wapakatikati pafupipafupi mphamvu ya 50KW-5000Kw.

5.The onboard phase sequence sequence adaptive circuit imatenga magawo atatu amagetsi kuti agwirizane mwachindunji popanda chosinthira chosinthira. Mzere wolowera wa dera lalikulu ukhoza kukhala wodziimira pa ndondomeko ya gawo.

6. Njira yodzitchinjiriza yomangidwa mumitundu yambiri. Gulu limodzi lophatikizidwa kwathunthu, lomwe limaphatikiza kukonzanso, inverter, chitetezo, ndi kuwongolera koyambira. ng’anjo yapakatikati imawongolera kuchulukira, kupitirira malire, malire amagetsi, malire apano, kusesa pafupipafupi, kutsekeka pafupipafupi, kuzindikira kwapakatikati, kuyambitsanso, magetsi, Zizindikiro zosiyanasiyana monga dongosolo ili ndi zabwino zodalirika kwambiri, kulondola kwambiri. , kukonza kosavuta, zigawo zochepa zotumizirana mauthenga, ndi zina zotero, kusintha mwachilengedwe komanso kukonza bwino.

7. Doko lanzeru la “RE” limagwirizanitsa ntchito monga “kuyamba”, “imitsani”, “kubwezeretsani”, ndi “kuwongolera kutali”, kupangitsa kuti zipangizozo zikhale zosavuta komanso zanzeru.

8. Mphamvu ya rectifier synchronous ya ng’anjo yapakati pafupipafupi imakhala ndi mitundu yosiyanasiyana yosinthika, ndipo imatha kugwira ntchito bwino kuyambira 220V mpaka 750V.

9. Buffer poyambira ndi njira yabwino yodziwira poyambira, kuti mzerewu uzitha kuzindikira kuyambika kwa mphamvu zonse (yambani pamalo aliwonse a potentiometer yamphamvu)

10. Kupatulapo woyendetsa ng’anjo yamoto yapakati ya inverter yomaliza, zonse zimaphatikizidwa mu bolodi losindikizidwa, ndi zipangizo zochepa zozungulira, palibe zigawo zotumizirana, zozungulira zosavuta, zowonongeka zosavuta, ndi kukonza bwino. Pamene dongosolo ulamuliro akulephera, basi m’malo bolodi yopuma. Komabe, sizidzakhudza kupanga kwachibadwa.　　

Chachiwiri, mawonekedwe a gulu lolamulira la ng’anjo yapakati pafupipafupi

1, dera lowongolera limayikidwa pa bolodi losindikizidwa

Mabwalo onse owongolera a ng’anjo yapakati pafupipafupi amakhala pa bolodi losindikizidwa, zomwe zimachepetsa kwambiri zolephera zomwe zimayambitsidwa ndi kusalumikizana bwino kwa zolumikizira. Njira yoyambira ya ng’anjo yapakatikati ya ng’anjo yapakatikati ndikusesa pafupipafupi zero kuyambira, zomwe zikutanthauza kuti voteji yamagetsi ndi yapano imawonjezeka pang’onopang’ono kuchokera ku zero panthawi yoyambira mphamvu, kotero palibe zomwe zikuchitika pagululi yamagetsi. Dera loyambira lili ndi gawo loyambira lobwereza bwereza, lomwe lingalepheretse kulephera kwamagetsi kwanthawi ndi nthawi ndikupanga kupambana koyambira 100%. Dera lotsata pafupipafupi limagwiritsa ntchito njira yanthawi zonse yotsatsira, yomwe imapangitsa kuti inverter ikhale ndi mphamvu zotsutsana ndi kusokoneza. Zigawo zazikulu zamagetsi Zomwe zimapangidwira zimatsimikiziridwa ndi kuyerekezera makompyuta, ndipo zimakhala zolondola kwambiri komanso zodalirika kuposa njira zamakono zamakono pogwiritsa ntchito machitidwe.

2, inverter mlatho katundu ndi ofanana resonant dera

Mlatho waukulu wa inverter mlatho wa ng’anjo yapakati pafupipafupi ndi dera lofananirako lopangidwa ndi ng’anjo yolowera ndi capacitor. Mu ng’anjo yopangira ng’anjo ya ng’anjo yapakatikati, capacitor ya mphamvu yomweyo imalumikizidwa kuti ipititse patsogolo voteji kotero kuti voteji yofika pang’anjoyo ndi 1500V.

3, misoperation sikudzakhudza dongosolo

Kutumiza kwa mphamvu ndi kutsatizana kwa mphamvu ya dera lalikulu ndi kulamulira dera la ng’anjo yapakati pafupipafupi ndi misoperation ya wogwiritsa ntchito sikudzakhala ndi zotsatirapo zoipa pa dongosolo. Ntchito zodzitchinjiriza zenizeni ndi izi: chitetezo chagawo; chitetezo chokwanira; chitetezo cha overvoltage; chitetezo chochepa; chitetezo chamadzi pansi pa kuthamanga kwa madzi. Dongosololi lili ndi ntchito zoteteza kwathunthu, ndipo limakhala ndi alamu yomveka komanso yowoneka bwino pakachitika cholakwika chilichonse, ndipo chipangizocho chimasiya kugwira ntchito nthawi yomweyo.

4, pogwiritsa ntchito magawo atatu owongolera mlatho wowongolera

The rectification mbali ya wapakatikati pafupipafupi ng’anjo ulamuliro bolodi utenga atatu gawo zonse kulamulira mlatho rectification, ulamuliro kuzungulira utenga panopa zoweta Integrated dera, ndi digito choyambitsa dera ndi kugunda kwabwino kusasinthasintha ndi amphamvu odana kusokoneza luso. Inverter imatengera kusesa pafupipafupi zero-voltage zofewa zoyambira, ndipo imakhala ndi kuzungulira kobwerezabwereza, potero kumapangitsa kudalirika koyambira. Malingana ngati katundu wamtundu wa katundu ndi wamkulu kuposa kapena wofanana ndi 2.5, chiwongoladzanja choyambira chikhoza kufika 100%, ndipo maulendo otsatirira pafupipafupi amatengera ndondomeko yachitsanzo, potero kupititsa patsogolo mphamvu yotsutsa kusokoneza kwa inverter system. Kuphatikiza apo, inverter yodziwikiratu θ yosinthira ma angle ndi chowongolera chowongolera amawonjezedwa ku gawo la inverter, lomwe limatha kutulutsa mphamvu pamtundu uliwonse wa katundu, kuti musunge nthawi, kupulumutsa magetsi, ndikuwongolera mphamvu ya gridi.
