    Chishandiso Chekudzivirira Kukwira (1)

     

    Chii chinonzi Surge Protective Device (SPD)?

    Chishandiso Chinodzivirira Kukwira (SPD) chikamu chesystem yekudzivirira kuiswa kwemagetsi. Chishandiso ichi chinobatanidza pamwe chete necircuit yemagetsi yemitoro yachinofanira kuchengetedza. Chishandiso chinodzivirira kukwira chinodzosera magetsi emagetsi senge nominal discharge current kubva ku short circuit. Chinoita izvozvo uchishandisa solid-state contact kana air-gap switch. Pamusoro pezvo, chishandiso chinodzivirira kukwira chinoshanda semudziyo unochengetedza load-safe load-safe shutoff device kana paine overcurrent uye chinovharazve chinodzora voltage level iri pamusoro pe rated voltage kana low voltage kana paine malfunction. Tinogona zvakare kushandisa mudziyo unodzivirira kukwira pamatanho ese enetwork yemagetsi. Iyi nzira inowanzo shandiswa uye inoshanda zvakanyanya yekudzivirira overvoltage.

    Mudziyo unodzivirira kukwira kwesimba wakabatana pamwe chete une impedance yakakwira. Nemamwe mashoko, huwandu hwe impedance yemutsara hwakaenzana ne impedance yemudziyo mumwe chete unodzivirira kukwira kwesimba. Kana overvoltage yekufamba kwenguva yaonekwa mukati mesystem, impedance yemudziyo inoderera, saka surge current inofambiswa nemudziyo unodzivirira kukwira kwesimba, ichipfuura michina inonzwisisika. Izvi zvinoreva kuchengetedza michina kubva ku overvoltage transients uye kusagadzikana, senge voltage spikes uye electrical surges, frequency variations, uye over-voltages zvinokonzerwa nekuchinja mashandiro kana mheni. Kana mushandisi akaisa surge strip kana surge protective device mu power wire inobva ku power utility inosanganisira smoothing capacitors, surge suppressors hadzidiwi nekuti ma capacitor aya atodzivirira kubva pakuchinja kamwe kamwe kwe voltage level.
