Converters Frequency waayo, matoorrada induction: mabda'a-socodsiinta iyo dayactirka

Maanta, converters inta jeer waayo, matoorrada induction ayaa badanaa loo isticmaalaa in industry ee. Waxaa xusid mudan in matoorada waxay leeyihiin in qaab-dhismeedka saddex windings, ay ku xiran yihiin on a "star" ama "xagalka". Laakiinse iyagu waxay leeyihiin hal khasaare - qabsato xawaaraha rotor waa mid aad u adag. Laakiin in markii hore joogi jiray. Haddaba, marka ay timaado in gargaarka ah ee korantada micro iyo xoog, hawshan waxaa fududeeyey. Leexo resistor ka variable ka bedeli kartaa xawaaraha in badan oo kala duwan.

Waayo, waa maxay ujeedada loo baahan yahay Converter inta jeer?

Functions in wax soo saarka this waa badan yihiin, laakiin inta badan lacagta yar loo isticmaalo. Dhab ahaantii, in la xakameeyo motor ku asynchronous waa lagama maarmaan si ay u awoodaan si ay ula qabsadaan ma aha oo kaliya xawaaraha wareeg ah, laakiin sidoo kale waqti dardargelinta, deceleration. Intaa waxaa dheer, nidaam kasta oo u baahan ilaalin. Waxaa lagama maarmaan ah in ay qaataan galay account Converter inta jeer ee hadda, taas oo uu isticmaalaa motor induction ah.

Ballaaran chastotniki loo isticmaalo habka dabeysha. Inkastoo istareexsan muuqata of wheel haadiyey, load ku on rotor waa mid aad u ballaaran. Iyo dardargelinta dagdag ah waa wax aan macquul aheyn. Sidoo kale, waxaa jira xaalado ay baahida loo qabo in la kordhiyo xawaaraha wareeg ah, socodka hawada ka badan ama ka yar ahaa. Laakiin tani waa tusaale kaliya, Converter inta jeer a waxaa badanaa loo isticmaalaa in nidaam kale. chastotnika la waafajinta kartaa xawaaraha conveyor ah, oo ka kooban dhowr marsami.

Mabda'a hawlgalka ee Converter soo noqnoqoshada

salaysan waa control microprocessor iyo wareeggeedii kala duwan oo diinta voltages AC iyo DC. geeddi socodka Dhowr dhacaan danab oo la bixisey in aqbasho awoodda qalab ee. Converter inta jeer Work waa mid fudud, waxaa ku filan si ay u eegaan saddex marxaladood. Marka hore, waxaa toosinta. Second, shaandhaynta ka. Saddexaad, inversion ah - beddelaad ah ee DC si AC.

Kaliya marxalad la soo dhaafay ka bedeli kartaa guryaha iyo goobaha hadda. By kala duwan dabeecadaha hadda waa la xakameyn karaa by xawaare rotor of motor ku asynchronous ah. In marxaladda inverter loo isticmaalo shirka awood of transistors. Saddexdaa walxood O - laba xoog oo ka mid ah gacanta. From baaxadda signalka codsatay in dambaysta ah waxay ku xidhan tahay dabeecadda hadda-danab at chastotnika wax soo saarka ah.

drive The lagu bedeli karaa?

converters Frequency waayo, matoorrada asynchronous bilaabay in ay isticmaalaan xad dhawaan. Laakiin sayniska ahaa si tartiib tartiib ah ku darina, rotor horeysay xawaaraha wareeg ah ayaa lagu kala duwanaayeen isticmaalaya geerka ama variator. Si kastaba ha ahaatee, ay gacanta ku sida aad u eheeyn, iyo xoogga drive wuu baabba'ay, sababtoo ah hababka loo baahnayn. gudbinta Belt ka caawisaa in la kordhiyo xawaaraha wareeg ah, laakiin in uu si sax ah u dhigay xuduudaha final waa mid aad u adag. Sababahan awgood, VSD aad uga fiican yahay, tan iyo markii ay iska ilaalisaa in khasaaro xoog ah. Laakiin ugu muhiimsan - waxa ay kuu ogolaanaya in aad beddesho oo xuduudaheedu drive ah, oo aan waxba beddelin makaanikada ah.

Waa kuwee inverter inay doortaan si loogu isticmaalo guriga?

Waa in la ogaadaa in xiriir la fulin karo shabakadda hal iyo saddex waji hadda. Waxaa oo dhan waxay ku xiran tahay nooc ka drive gaar ah, oo haddii si gaar ah, kaas oo circuit inverter of motor induction ah ee loo isticmaalo in wax soo saarka. Si loo fahmo mabda'a shaqeeya, waxa ku filan in ay eegaan qaab-dhismeedka ka mid ah qalabka. unit ugu horeeya ee - rectifier ah, kaas oo la socday dioska- Semiconductor. circuit buundada Tani diinta kaliya ama saddex AC wajiga si DC. Waayo, guriga isticmaalaan waa in aad doorato kuwa lagu daydo chastotnikov kuwaas oo gashiga ku xiran yihiin hal waji talantaalli hadda. doorashooyin la xiriira in guryaha gaarka loo leeyahay si ay u qabtaan network saddex waji leh oo waa dhibaato, oo aan faa'iido, maxaa yeelay, waa in aad isticmaasho a more casri ah account oo ka mid ah qalabka korontada.

Tiirarka ugu muhiimsan drive

Little ayaa la sheegay in circuit waa inverter ah. Laakiin waxaad u baahan tahay in ay tixgeliso si faahfaahsan waxbarasho faahfaahsan. In diinta koowaad - AC sixitaan. Macna ma laha inta badan ee wajiga aqbasho waa (hal ama saddex) bixisey, at saarka ee rectifier aad ka heli danab joogto ah unipolar (mid ka mid ah lagu daray oo ka mid ah laga jaray) ee 220 volts. Waxaa aad u badan oo u dhexeeya wajiga iyo dhex-dhexaad ah.

Tan waxa la unit filter a, taas oo ka caawisaa laga takhaluso oo dhan qaybaha variable of hadda ku saxo. Oo marxaladda ugu dambaysa waa la rogay - ka DC waa variable taasi oo ka transistors awoodda, ay gacanta ku microcontroller ah. Sida caadiga ah, waayo, inverters matoorrada induction leeyihiin bandhigay LCD monochrome ah, taasi oo muujinaysa xuduudaha loo baahan yahay.

Ma suurogalbaa in la sameeyo qalab naftaada?

Production qalab la xidhiidha dhibaatooyin badan. Waxaad u baahan tahay si ay u bartaan aasaaska microcontrollers barnaamijyada in la kordhiyo fursadaha of qalab ah. Waxaa muhiim ah in ay tixgeliyaan dhammaan shuruudaha aasaasiga ah. Tusaale ahaan, xiritaanka degdeg ah si toos ah marka aad iyo aad ugu badan la ogolaan karo hadda oo la wada baabbi'iyey by matoorka. Si arrintan loo sameeyo, waxaad u baahan tahay si ay u dejiyaan wax soo saarka gudbiyeyaasha hadda, kaas oo qaadi doona la socodka joogtada ah. Sidoo kale, waa in ay bixiyaan waxyaalaha qaboojinta firfircoon oo dadban ee nidaamka awoodda - dioska- iyo transistors, iyo sidoo kale gab qalabka in kulaylku xad-dhaaf ah. Kaliya kiiskan, converters inta jeer waayo, matoorrada asynchronous si ammaan ah ku shaqeeya karo.
