Chii chinonzi Surge Protective Device (SPD)?
Iyo Surge Protective Device (SPD) chikamu chemagetsi ekudzivirira ekudzivirira system.Ichi chigadziri chinobatanidza mukuenderana nemagetsi emagetsi ekutakura mitoro iyo inofanirwa kuchengetedza.Iyo yekuvhiya inodzivirira mudziyo inodzoreredza mafambiro emagetsi senge zita rekuburitsa ikozvino kubva kupfupi wedunhu.Inoita izvozvo uchishandisa ingave yakasimba-nyika yekubata kana mhepo-gap switch.Pamusoro pezvo, chidziviriro chekudzivirira chinoshanda sechidzitiro-chakachengeteka chekuvhara dhizaini yemamiriro ekunze uye recloser inodzora chiyero chevoltage pamusoro peiyo yakayerwa voltage kana yakaderera voltage kana paine chikanganiso.Isu tinogona zvakare kushandisa iyo yekuvhiya inodzivirira mudziyo pamatanho ese emagetsi ekupa network.Iyi nzira ndiyo inowanzo nyanya kushandiswa uye inoshanda zvakanyanya yekudzivirira overvoltage.
Surge inodzivirira mudziyo yakabatana mune parallel inoratidzira yakakwira impedance.Mune mamwe mazwi, huwandu hweakateedzana impedance yakaenzana neiyo impedance yeimwe yekuvhiya yekudzivirira mudziyo.Kana iyo yenguva pfupi yakawandisa yaonekwa mukati meiyo sisitimu, iyo impedance yemuchina inodzikira, saka kuvhiya ikozvino kunofambiswa nemudziyo wekudzivirira wekuvhiya, uchipfuura nemidziyo inonzwisisika.Iko kuchengetedza michina kubva kune overvoltage transients uye kuvhiringika, senge voltage spikes uye magetsi masurges, frequency kusiyanisa, uye over-voltages anokonzerwa nekuchinja mashandiro kana mheni.Kana mushandisi akaisa surge strip kana surge yekudzivirira mudziyo mumutsara wemagetsi unobva kumagetsi utility inosanganisira smoothing capacitors, suppressors haifanirwe nekuti aya ma capacitor anotodzivirira kubva kamwe kamwe shanduko yevoltage level.
