Sei mabhokisi ekuparadzira achifanira kuve nemudziyo unodzivirira kukwira kwemvura?

Munyika yanhasi yafambira mberi mune zvetekinoroji, kudiwa kwemudziyo wekudzivirira kukwira kwemvura (SPD) mumabhokisi ekuparadzira hazvigone kurerutswa. Zvidziviriro zvema "surge" zvinoita basa rakakosha mukudzivirira michina yemagetsi neyemagetsi kubva pakurohwa nemheni uye kukuvara kwe "overvoltage". Voltage yakakwira uye simba rinogadzirwa panguva yekurohwa nemheni, pamwe chete nenguva pfupi yekuburitswa kwesimba, zvinotyisidzira zvikuru tambo dzemagetsi, tambo dzemasaini, ma "antenna feeders" uye mapaipi esimbi. Izvi zvinogona kuva nemigumisiro yakaipa kune michina yemagetsi neyemagetsi uye masisitimu enetwork yeruzivo. Voltage yakasara uye mheni ye induction inogadzirwa nekurohwa nemheni zvinogona kukonzera ma "short circuits", kupiswa, uye kuputika mumidziyo yemagetsi, zvichikonzera kurasikirwa kukuru. Nokudaro, zvakakosha kuisa michina yekudzivirira ma "surge" mumabhokisi ekuparadzira kuderedza njodzi idzi uye kuve nechokwadi chekuchengetedzwa kwemidziyo inokosha uye masisitimu.

Mheni painoburitswa, simba rinoburitswa rinokura uye rinogona kupinda zvakananga kana zvisina kunanga muhurongwa hwakasiyana-siyana. Matanho ekudzivirira mheni ekunze akadai sema "lightning rods" haana kukwana kudzikamisa kukuvara kunogona kukonzerwa nemafungu emheni. Apa ndipo panoshanda michina yekudzivirira mafungu. Yakagadzirirwa kudzivirira kubva pakuroverwa nemheni uye kugadzirisa ma "resonant overvoltages" mumitsetse yekugovera ine ma "low-voltage distribution lines". Chinodzivirira mafungu chinokurumidza kutumira ma "high voltage" uye "large current" panyika kuburikidza newaya yekudzivirira mafungu, ichidzivirira bhokisi rekugovera kubva pakuroverwa nemheni uye ichideredza kukanganiswa kwe "overvoltage". Saka, kuisa "surge protector" mubhokisi rekugovera inzira yekudzivirira inodiwa mu "low-voltage power supply system".

Kukosha kwezvidziviriro zvemagetsi mumabhokisi ekuparadzira hakufanirwe kutaurwa zvakanyanya, kunyanya kana paine njodzi huru dzechisikigo dzakadai sekurova kwemheni. Kukuvadzwa kunogona kukonzerwa nekurova kwemheni uye kukwira kwemagetsi kumidziyo yemagetsi nemagetsi uye masisitimu enetwork yeruzivo kunoratidza kudiwa kwekukurumidzira kwematanho ekudzivirira anoshanda. Nekuisa zvidziviriro zvemagetsi mumabhokisi ekuparadzira, unogona kuderedza zvakanyanya njodzi yekukuvadzwa kunokonzerwa nekurova kwemheni uye kukwira kwemagetsi, uchivimbisa kuchengetedzeka uye kushanda kwemidziyo yakakosha nemasisitimu.
