Ongororo yeThyristor Inoshandura Circuit muMedium Frequency Inverter Spot Welding Machine

Iyo thyristor switching circuit inoita basa rakakosha mukushanda kwepakati frequency inverter spot welding muchina. Inobatsira kutonga uye kutonga kwesimba remagetsi, zvichiita kuti zvive zvakanyatsojeka uye zvinogadzirisa maitiro ekugadzirisa. Muchikamu chino, tichapa kuongorora kwakadzama kwe thyristor switching circuit mune yepakati frequency inverter spot welding machine.

1. Basic Structure yeThyristor Switching Circuit: Iyo thyristor inoshandura dunhu ine akati wandei akakosha zvikamu, zvinosanganisira thyristors (inozivikanwawo sesilicon-inodzorwa rectifiers), gedhi rekudzora maseketi, trigger matunhu, uye ekudzivirira emidziyo. Izvi zvikamu zvinoshanda pamwe chete kudzora kuyerera kwemagetsi ikozvino uye kuve nechokwadi chekuchengetedza uye kwakavimbika kushanda kwemuchina welding.
2. Basa rema Thyristors: Thyristors ma semiconductor zvishandiso zvinoshanda semagetsi anodzorwa switch. Ivo vanobvumira ikozvino kuyerera munzira imwe kana yakonzeresa, uye kana ichingoitisa, ivo vanoramba vachiitisa kusvika madonhwe ezvino adonha pazasi pechimwe chikumbaridzo. Muchikamu chekushandura, thyristors inoshandiswa kudzora magetsi kune welding transformer.
3. Gate Control Circuits: Magedhi ekudzora maseketi ane basa rekukonzeresa ma thyristors uye kudzora maitiro avo ekuchinja. Ivo vanogadzira chaiyo uye yakatarwa gedhi masaini anotanga kufambisa kwema thyristors. Magedhi ekudzora maseketi akagadzirirwa kuve nechokwadi chekuenzanisa uye kurongeka kweiyo thyristor switching process.
4. Trigger Circuits: Iwo anokonzeresa maseketi anopa anodiwa anokonzeresa masaini kumagedhi ekudzora maseketi. Aya masaini anogadzirwa zvichibva pane inodiwa welding paramita, senge welding current, welding time, uye electrode force. Iwo anokonzeresa maseketi anovimbisa kuti thyristors inokonzeresa panguva yakakodzera kuti iwane inodiwa welding maitiro.
5. Zvidziviriro Zvishandiso: Kuti uve nechokwadi chekuchengetedzwa kwemuchina welding uye kudzivirira kukuvadzwa kwezvikamu, zvidziviriro zvekudzivirira zvinosanganiswa mu thyristor switching circuit. Zvishandiso izvi zvinosanganisira overcurrent kudzivirira, overvoltage kudzivirira, uye tembiricha yekutarisa. Ivo vanoona uye vanopindura kune abnormal mamiriro, akadai yakawandisa ikozvino kana voltage, uye activate matanho ekudzivirira kudzivirira kutadza kwehurongwa kana kukuvara.
6. Kudzora uye Kudzora kweSimba: Iyo thyristor switching wedunhu inogonesa kudzora uye kutonga kwesimba mune yepakati frequency inverter nzvimbo welding muchina. Nekugadzirisa zvinokonzeresa masaini uye magedhi ekudzora maseketi, simba rinopihwa kune welding transformer rinogona kugadziridzwa kuti riwane inodiwa welding maitiro, senge weld simba, kupinda, uye kupisa kupinza.

Iyo thyristor switching circuit mune yepakati frequency inverter spot welding muchina chinhu chakakosha chinogonesa kunyatso kudzora uye kudzora kwesimba remagetsi. Kuburikidza nekubatanidzwa kwe thyristors, gedhi rekudzora maseketi, trigger maseketi, uye ekudzivirira emidziyo, muchina welding unogona kuendesa kwakaringana uye nekuita welding maitiro. Kuongororwa kweiyo thyristor switching circuit inopa nzwisiso muchimiro chayo chakakosha uye kushanda kwayo, kuratidza kukosha kwayo mukuwana emhando yepamusoro welds uye kuve nechokwadi chekushanda kwakachengeteka kwemuchina welding.
