Detailed tsananguro ye thyristor module application

1. Nzvimbo dzekushandisa dzeSCR modules

Iyi smart module inoshandiswa zvakanyanya mumashandisirwo akadai sekudzora tembiricha, dimming, excitation, electroplating, electrolysis, kuchaja uye kuburitsa, magetsi emagetsi welding, plasma arcs, inverter magetsi emagetsi, nezvimwewo, uko simba remagetsi rinoda kugadziridzwa uye kushandurwa, zvakadai. seindasitiri, kutaurirana, uye zvechiuto. Yakasiyana-siyana magetsi ekutonga, magetsi emagetsi, nezvimwe zvinogona zvakare kubatanidzwa kune akawanda-basa rekudzora bhodhi kuburikidza nechiteshi chekutonga chemodule kuona mabasa akadai sekudzikamisa kwazvino, kudzikamisa kwemagetsi, kutanga kwakapfava, nezvimwe, uye unogona kuona pamusoro pezvino, pamusoro pemagetsi, pamusoro petembiricha, uye kuenzana. Basa rekudzivirira.

2. Kudzora nzira ye thyristor module

Kuburikidza neiyo yekuisa module control interface inogadziriswa voltage kana yazvino chiratidzo, iyo inobuda voltage yemodule inogona kugadziridzwa zvakanaka nekugadzirisa saizi yechiratidzo, kuitira kuti uone maitiro eiyo module kubuda voltage kubva ku0V kuenda kune chero nzvimbo kana zvese conduction. .

Voltage kana chiratidzo chemazuva ano chinogona kutorwa kubva kune akasiyana-siyana ekudzora zviridzwa, komputa D / A kubuda, potentiometer inopatsanura zvakananga voltage kubva kuDC magetsi uye dzimwe nzira; control sign inotora 0～5V, 0～10V, 4～20mA nzira nhatu dzinowanzoshandiswa Kudzora fomu.

3. Kudzora chiteshi uye kutonga mutsara we SCR module

Iyo module control terminal interface ine mafomu matatu: 5-pini, 9-pini uye 15-pini, inoenderana ne5-pini, 9-pini, uye 15-pini yekudzora mitsetse zvichiteerana. Zvigadzirwa zvinoshandisa masaini emagetsi zvinongoshandisa yekutanga-pini shanu chiteshi, uye mamwe mapini asina chinhu. Iyo 9-pini ikozvino chiratidzo ndiyo inopinza chiratidzo. Waya yemhangura yenzvimbo inodzivirira yewaya yekudzora inofanirwa kusungirirwa kune DC simba pasi waya. Chenjerera kuti usabatana nemamwe mapini. Iwo materminal ane mapfupi-akatenderedzwa kudzivirira kusashanda kana kukwanisika kupisa kwemodule.

Kune nhamba pane module control port socket uye control line socket, ndapota nyorera imwe neimwe, uye usadzorere kubatana. Iwo ari pamusoro apa zviteshi zvitanhatu ndiwo ekutanga madoko emodule, uye mamwe madoko akakosha madoko, ayo anongoshandiswa muzvigadzirwa zvine akawanda-mabasa. Tsoka dzasara dzezvakajairwa zvinodzora zvigadzirwa hazvina chinhu.

4. Tafura yekuenzanisa yebasa repini imwe neimwe uye ruvara rwemutsara wekutonga

Pini inoshanda yepini nhamba uye inofambirana neruvara rwepini 5-pini yekubatanidza 9-pini yekubatanidza 15-pini yekubatanidza +12V5 (tsvuku) 1 (tsvuku) 1 (tsvuku) GND4 (dema) 2 (dema) 2 (dema) GND13 (dema) 3 (dema nechena) 3 (dema nechena) CON10V2 (yero yepakati) 4 (yero yepakati) 4 (yero yepakati) TESTE1 (orenji) 5 (orenji) 5 (orenji) CON20mA 9 (brown) 9 (brown)

5. Sangana nemamiriro anodiwa ebasa reSCR module

Mamiriro anotevera anofanirwa kusangana mukushandiswa kwemodule:

(1) + 12V DC magetsi ekupa: iyo inoshanda simba rekupa mukati mekudzora wedunhu remodule.

① Kubuda kwemagetsi kunodiwa: +12V magetsi emagetsi: 12±0.5V, ripple voltage iri pasi pe20mv.

② Zvazvino zvinobuda zvinodiwa: zvigadzirwa zvine zita remazuva ano zvisingasviki mazana mashanu amperes: I+500V> 12A, zvigadzirwa zvine zita rezvino zvinodarika mazana mashanu amperes: I+0.5V> 500A.

(2) Kudzora chiratidzo: 0～10V kana 4～20mA chiratidzo chekudzora, iyo inoshandiswa kugadzirisa kubuda kwemagetsi. Iyo danda rakanaka rakabatana neCON10V kana CON20mA, uye iro rakaipa rakabatana neGND1.

(3) Simba rekupa uye mutoro: Simba remagetsi rinowanzoita grid magetsi, ine voltage iri pasi pe460V kana magetsi ekugadzirisa magetsi, akabatanidzwa kune inopinza terminal ye module; mutoro mudziyo wemagetsi, wakabatana kune inobuda terminal yemodule.

6. Ukama huri pakati pekona yekufambisa uye kubuda kweiyo module

Iyo conduction angle ye module yakanangana neiyo yakanyanya ikozvino iyo module inogona kubuda. Ikozvino yezita remodule ndiyo yakanyanya ikozvino inogona kubuda pahupamhi hwema conduction angle. Pane diki conduction angle (reshiyo yekubuda kwevoltage kune yekupinza voltage idiki kwazvo), iyo inobuda ikozvino yepamusoro kukosha yakakura kwazvo, asi inoshanda kukosha kweiyo yazvino idiki kwazvo (DC metres inowanzoratidza kukosha kweavhareji, uye AC metres. ratidza isiri-sinusoidal current, iyo idiki pane kukosha chaiko) , Asi kukosha kunoshanda kwekubuda kwazvino kwakakura kwazvo, uye kupisa kweiyo semiconductor mudziyo inoenderana neskweya yehukoshi hunoshanda, izvo zvichaita kuti module kupisa kana kutopisa. Naizvozvo, iyo module inofanirwa kusarudzwa kuti ishande pamusoro pe65% yeiyo yakanyanya conduction angle, uye iyo yekudzora voltage inofanira kunge iri pamusoro pe5V.

7. Nzira yekusarudza ye SCR module tsanangudzo

Tichifunga kuti zvigadzirwa zve thyristor kazhinji zvisiri-sinusoidal mafungu, pane dambudziko rekuita angle uye mutoro wazvino une kumwe kushanduka uye kusagadzikana zvinhu, uye thyristor chip haina kushomeka kuramba kune yazvino maitiro, saka inofanirwa kusarudzwa kana module yazvino zvinotsanangurwa. vakasarudzwa. Siya imwe margin. Iyo yakakurudzirwa nzira yekusarudza inogona kuverengerwa zvinoenderana neinotevera fomula:

Ini> K×I load×U maximum∕U chaiyo

K: kuchengeteka chinhu, resistive mutoro K = 1.5, inductive mutoro K = 2;

Iload: iyo yakawanda ikozvino inoyerera kuburikidza nemutoro; Uactual: iyo shoma voltage pamutoro;

Umax: iyo yakanyanya voltage iyo module inogona kubuda; (three-phase rectifier module is 1.35 times the input voltage, single-phase rectifier module is 0.9 times the input voltage, and the other specifications is 1.0 times);

Ini: Izvo zvishoma zvazvino zvemodule zvinoda kusarudzwa, uye zita rezvino remodule rinofanira kunge rakakura kupfuura kukosha uku.

Mamiriro ekupisa ekupisa kweiyo module anoenderana zvakananga nehupenyu hwesevhisi uye yenguva pfupi yekuremedza huwandu hwechigadzirwa. Iyo yakaderera tembiricha, iyo yakakura kubuda ikozvino kweiyo module. Naizvozvo, radiator uye feni inofanirwa kuve yakashongedzerwa mukushandiswa. Inokurudzirwa kushandisa zvigadzirwa nekudzivirira kwekupisa. Kana pane mvura-yakatonhorera kupisa mamiriro ekupisa, mvura-yakanyorovesa kupisa kupisa inosarudzwa. Mushure mekuverenga kwakasimba, isu takasarudza maredhiyamu modhi ayo akasiyana ezvigadzirwa anofanirwa kuve akashongedzerwa nawo. Inokurudzirwa kushandisa ma radiator uye mafeni anofananidzwa nemugadziri. Kana mushandisi achiigadzirira, sarudza zvinoenderana neanotevera masimboti:

1. Mhepo inomhanya yeaxial flow fan inofanira kuva yakakura kudarika 6m / s;

2. Inofanirwa kuve nekukwanisa kuve nechokwadi chekuti tembiricha yekutonhora yepasi ndiro haina kupfuura 80 ℃ kana module iri kushanda zvakajairika;

3. Kana iyo module mutoro wakareruka, saizi yeradiator inogona kuderedzwa kana kutonhora kwepanyama kunogona kugamuchirwa;

4. Kana kutonhora kwechisikigo kuchishandiswa, mhepo yakatenderedza radiator inogona kuwana convection uye zvakakodzera kuwedzera nzvimbo yeradiator;

5. Yese screws yekusimbisa module inofanira kusimbiswa, uye crimping terminals inofanira kusungirirwa zvakasimba kuderedza chizvarwa chekupisa kwechipiri. Chigadziko chegiresi chinopisa kana thermal pad saizi yeplate yepasi inofanira kuiswa pakati pemodule yepasi ndiro uye radiator. Kuti uwane yakanakisa kupisa kupisa mhedzisiro.

8. Kuiswa uye kuchengetedza thyristor module

(1) Pfekedza dhizaini ye thermally conductive silicone girisi pamusoro peiyo module yekupisa-inobata pasi ndiro uye pamusoro peiyo radiator zvakaenzana, uye wozogadzirisa module paradiyeta nemakona mana. Usaomesa zvigadziriso zvekugadzirisa panguva. Zvakaenzana, dzokorora kakawanda kusvika yakasimba, kuitira kuti moduli yepasi ndiro iri pedyo nepamusoro peiyo radiator.

(2) Mushure mekuunganidza radiator uye fan zvinoenderana nezvinodiwa, zvigadzirise zvakamira panzvimbo yakakodzera yechasi.

(3) Sunga waya yemhangura zvakasimba netepi yerin’i yemusoro, zvichida kunyudzwa murata, wozoisa pachubhu inodzivirira kupisa-inopwanyika, woipisa nemhepo inopisa kuti iputse. Gadzirisa magumo ekupedzisira pane module electrode uye chengetedza yakanaka ndege yekumanikidza kubata. Izvo zvinorambidzwa zvachose kucheka tambo yemhangura yetambo zvakananga pane module electrode.

(4) Kuti uwedzere hupenyu hwebasa rechigadzirwa, zvinokurudzirwa kuti uzvichengetedze mwedzi yese ye3-4, kutsiva mafuta ekupisa, kubvisa guruva repamusoro, uye simbisa crimping screws.

Iyo kambani inokurudzira zvigadzirwa zvemodule: MTC thyristor module, MDC rectifier module, MFC module, nezvimwe.
