Ntchito Yaikulu

Ntchito yayikulu yamagetsi owongolera.
1. Kukhazikika kwamagetsi.
Magetsi a gridi akasinthasintha nthawi yomweyo, chowongolera voteji chimalipira matalikidwe amagetsi ndi liwiro la 10-30ms, ndikupangitsa kuti ikhale yokhazikika mkati mwa ± 2%.
2. Mipikisano zinchito Integrated chitetezo.
Magetsi owongolera kuphatikiza pakukhazikika kokhazikika kwamagetsi amagetsi ayeneranso kukhala ndi chitetezo chamagetsi (kuposa + 10% yamagetsi otulutsa), chitetezo chapansi pamagetsi (chochepera -10% chamagetsi otulutsa), chitetezo chagawo. , chitetezo chaching'ono chodzaza ndi ntchito zofunika kwambiri zachitetezo.
3. Spike pulse kupondereza (ngati mukufuna).
Gulu lamagetsi nthawi zina limakhala ndi matalikidwe okwera kwambiri, m'lifupi mwake ndikugunda kwapang'onopang'ono, ndipo imadutsa pamagetsi otsika kupirira zida zamagetsi.Zigawo zotsutsana ndi ma surge zamagetsi oyendetsedwa bwino zimatha kukhala ndi gawo labwino kwambiri popondereza ma pulse akuthwa ngati amenewa.
4. kudzipatula kwa conductive EMI electromagnetic interference (ngati mukufuna).
Zida za CNC zambiri AC/DC rectifier + PFC high-frequency power factor correction, palokha kuchuluka kwa kusokoneza nthawi yomweyo gwero la kusokoneza lilinso ndi zofunika kwambiri.Zowongolera zamagetsi zosefera zamagetsi zimatha kusiyanitsa kusokoneza kwa gridi ku zida panthawi imodzimodziyo zithanso kulekanitsa kusokoneza kwa zida ku gululi.
5. chitetezo cha mphezi (posankha).
Ayenera kukhala ndi mwayi wodziteteza ku mphepo yamkuntho.

Magulu

DC voltage regulator ikhoza kugawidwa m'magulu awiri.

1, kusintha mtundu
Mtundu wosiyana wa magetsi okhazikika kuchokera kumagetsi oyendetsedwa bwino ndi magetsi osinthika a DC, omwe ali ndi mtundu wozungulira wa flyback imodzi, kutsogolo, theka-mlatho, kukankha-kukoka ndi mlatho wonse.Kusiyana kwakukulu pakati pa magetsi awa ndi mzere wamagetsi ndikuti thiransifoma sigwira ntchito pafupipafupi koma ma kilohertz makumi angapo mpaka ma megahertz angapo.Ntchito chubu sikugwira ntchito mu machulukitsidwe ndi odulidwa m'dera kuti ndi kusintha boma;kusintha magetsi motere.

2 ,Mzere
Liniya voteji chowongolera ali ndi mbali wamba kuti mphamvu chipangizo chowongolera chubu ntchito mu liniya zone, kudalira dontho voteji pakati pa chubu chowongolera kuti bata linanena bungwe.Chifukwa cha kutayika kwakukulu kwa chubu chowongolera, choyimira chachikulu chiyenera kuyikidwa kuti chiwononge kutentha kwa icho.Transformer imalemeranso chifukwa imagwira ntchito pa 50Hz.

Ubwino wa mtundu uwu wa magetsi ndi kukhazikika kwakukulu, kuphulika kwazing'ono, kudalirika kwakukulu, kosavuta kupanga angapo, kusinthika kosalekeza kwa mankhwala omalizidwa.Zoyipa zake ndizakuti ndi zazikulu, zochulukirapo, komanso sizigwira ntchito bwino.Mtundu uwu wa magetsi okhazikika ndipo pali mitundu yambiri, kuchokera ku chikhalidwe cha linanena bungwe akhoza kugawidwa mu voteji okhazikika magetsi ndi panopa okhazikika magetsi ndi seti ya voteji kukhazikika, kukhazikika panopa mu voteji khola, ndi panopa (wapawiri-khola). ) magetsi.The linanena bungwe mtengo akhoza kugawidwa mu fixed mfundo linanena bungwe magetsi, gulu lophimba chosinthika, ndi potentiometer mosalekeza chosinthika mtundu angapo.Kuchokera pazotulutsa, chiwonetserochi chikhoza kugawidwa mumtundu wa pointer ndi mtundu wowonetsera digito, ndi zina zotero. 三、

yambitsani

DC kusintha magetsi.
Ubwino wosinthira magetsi ndi kukula kwake kochepa, kupepuka, kukhazikika, komanso kudalirika.Amapezeka mumagulu amphamvu kuchokera ku ma watts angapo mpaka ma kilowatts angapo.Nawa zida zingapo zosinthira magetsi
1. Zida zamagetsi zamagetsi
Magetsi olumikizirana kwenikweni ndi magetsi amtundu wa DC/DC, koma nthawi zambiri amakhala magetsi a DC-48V kapena -24V, ndi batire yosungira yamagetsi a DC, voteji ya DC mumagetsi oyendera dera, nthawi zambiri amakhala. ogaŵikana chapakati magetsi, wosanjikiza magetsi, ndi limodzi bolodi magetsi atatu, chotsirizira ndi odalirika kwambiri.
2. AC/DC
Mphamvu yamtundu uwu, yomwe imadziwikanso kuti primary power supply, imalandira mphamvu kuchokera ku gridi yamagetsi ndikupeza magetsi okwera kwambiri a DC kupyolera mu kukonzanso kwamagetsi apamwamba ndi kusefa kwa DC / DC converter kuti ipeze magetsi amodzi kapena angapo okhazikika a DC potulutsa, ndi mphamvu yoyambira ma watts angapo mpaka ma kilowatt angapo.Pali mitundu yosiyanasiyana yazinthu zotere, ndipo magetsi oyambira (AC220 input, DC48V, kapena 24V output) mumagetsi olumikizirana nawonso ndi amtunduwu, kutengera zosowa za wogwiritsa ntchito.
3. Modular magetsi
Ndi chitukuko chofulumira cha sayansi ndi zamakono, kudalirika kwa magetsi, ndi chiwerengero cha mphamvu / voliyumu chikuchulukirachulukira, mphamvu yamagetsi yamagetsi ikuwonetseratu kupambana kwake, imagwira ntchito pafupipafupi, kukula kochepa, kudalirika kwakukulu, kuyika kosavuta. ndi kuphatikiza kukulitsa, kotero kumagwiritsidwa ntchito kwambiri.Ngakhale pali lolingana zoweta gawo kupanga, chifukwa ndondomeko kupanga si anagwira ndi mlingo wa mayiko, kulephera mlingo ndi mkulu.
4. Mphamvu zamagetsi pawailesi
Kuyika kwamagetsi pawayilesi AC220V/110V, kutulutsa DC13.8V, mphamvu ndi mphamvu ya wayilesi, ma amps ochepa, ndi mazana a ma amps akupezeka.Pofuna kupewa kulephera kwa magetsi a gridi ya AC kukhudza ntchito ya wailesi, ndikufunika kukhala ndi paketi ya batri ngati zosunga zobwezeretsera, kotero mtundu uwu wamagetsi kuwonjezera pa kutulutsa kwa voltage ya 13.8V DC ilinso ndi batire yothamangitsa basi kutembenuka.
5. DC/DC
Munjira yolumikizirana, yomwe imadziwikanso kuti yachiwiri yamagetsi, ndimagetsi oyambira magetsi kapena batire ya DC kuti ipereke magetsi olowera a DC, pambuyo pa kutembenuka kwa DC / DC kumbali yotulutsa kuti mupeze magetsi a DC kapena ma voltages angapo a DC.
Ngakhale kuti gawo lamagetsi la DC / DC ndilokwera mtengo kwambiri, kuchokera pakuwona mtengo wonse wazomwe zimagwiritsidwa ntchito nthawi yayitali, makamaka chifukwa cha kulephera kwadongosolo komanso kukwera mtengo kwa kukonza ndi kutayika kwabwino, kusankha gawo lamagetsi. ikadali yotsika mtengo, ndiyeneranso kutchula apa ndi Roche converter dera, mwayi wake wapadera ndi mawonekedwe osavuta a dera, kuchita bwino kwambiri komanso kutulutsa magetsi komanso mtengo wapano wa ripple pafupi ndi ziro.
6. Zida zamagetsi zapadera
Magetsi apamwamba komanso magetsi otsika, magetsi apamwamba kwambiri, 400Hz athandizira magetsi a AC/DC, ndi zina zotere zitha kusankhidwa molingana ndi zosowa zapadera.
