Basa rekudzivirira kudzivirira

Surge, (Surge dziviriro Chishandiso) chinhu chakakosha mukudzivirira kwemheni yemidziyo yemagetsi.Basa remudziviriri wekuvhiya ndere kudzikamisa iyo pakarepo overvoltage inopinda mumutsara wemagetsi uye chiratidzo chekufambisa mutsara mukati meiyo voltage renji iyo mudziyo kana system inogona kumira, kana kuburitsa mheni yakasimba iripo muvhu kuchengetedza midziyo yakachengetedzwa kana system. kubva pakukuvadzwa.kukuvadzwa nekukanganisa.

Nheyo yekushanda yemudziviriri wekuvhiya yakaita seiyi: muchengeti wekuvhiya anowanzo kuisirwa kumigumo yese yemudziyo wakadzivirirwa uye wakadzikwa.Pasi pemamiriro ekushanda akajairwa, muchengeti wekuvhiya anopa kukwirisa kune yakajairika simba frequency voltage, uye inenge isina ikozvino inoyerera kuburikidza nayo, iyo yakaenzana neyakavhurika dunhu;kana kuwedzeredza kwechinguvana kunoitika muhurongwa, muchengeti wekuvhiya anozopindura kune yakakwira-frequency transient overvoltages.Iyo voltage inopa yakaderera impedance, yakaenzana nepfupi-kutenderera iyo yakadzivirirwa michina.

1. Shandura mhando: Iyo yekushanda kwayo ndeyekuti kana pasina instantaneous overvoltage, inopa yakakwira impedance, asi kana ichinge yapindura mheni instantaneous overvoltage, impedance yayo inongoerekana yachinja kune yakaderera kukosha, ichibvumira mheni ikozvino kupfuura.Kana ichishandiswa semidziyo yakadaro, zvishandiso zvinosanganisira: kuburitsa gap, gasi rekuburitsa machubhu, thyristors, nezvimwe.

2. Voltage-limiting type: Yayo kushanda kwayo ndeyekuti yakakwirira impedance kana pasina pakarepo overvoltage, asi impedance yayo icharamba ichiderera nekuwedzera kwekuvhiya ikozvino uye voltage, uye ikozvino-voltage hunhu hwakasimba nonlinear.Midziyo inoshandiswa pamidziyo yakadai ndeye: zinc oxide, varistor, suppressor diode, avalanche diode, nezvimwe.

3. Shunt type kana choke type

Shunt mhando: inoenderana nemidziyo yakadzivirirwa, inopa yakaderera impedance kune mheni pulses uye yakakwirira impedance kune yakajairika kushanda frequency.

Choke Type: Munhevedzano nemidziyo yakadzivirirwa, inopa yakakwira impedance kune mheni pulses uye yakaderera impedance kune yakajairika kushanda frequency.

Zvishandiso zvinoshandiswa semidziyo yakadai zvinosanganisira: macoil ekudzipa, mafirita epamusoro-soro, mafirita epasi-pasi, 1/4 wavelength mapfupi-circuiters, nezvimwe zvakadaro.
