Sei Iyo Surge Protector Chishandiso Chichipisa?

Thesurge protectorchinhu chakakosha chekudzivirira overvoltage kukanganisa kwemidziyo yemagetsi muzvivakwa.Pasi pekuchengetedzwa kweSPD, kunyange kana mheni inosvika makumi emakiromita inopinda mukati medunhu remukati, muchengeti wekudzivirira anogona kukurumidza kubuda kune pasi pevhu regidhi, kuchengetedza kushanda kwakagadzikana uye kwakachengeteka kwemidziyo yedu yemagetsi.Nekudaro, mumakore achangopfuura, dambudziko remoto rekuvhiya kudzivirira midziyo rakaitika nguva nenguva.Kunyangwe iyo yekuvhiya mudziviriri yakachengeteka kana kwete uye nei iyo yekuvhiya mudziviriri ichipisa yave kunetsekana nevashandisi.Nhasi, isu tichakupa iwe yakakurumbira sainzi yekuti sei iyo yekuvhiya inodzivirira ichipisa.

Mheni yazvino, kazhinji ine yakakwira ikozvino, inokurumidza kukurumidza hunhu, kazhinji mumakumi kana mazana emazana emamicroseconds achapfuura makumi emakiromita epamusoro-soro, kana akasaburitswa, achakonzera mhedzisiro inouraya pakushandiswa kwemidziyo yemagetsi uye hupenyu hwevanhu.Surge mudziviriri anoshandisa pressure-sensitive resistors kana discharge gap, mukushanda kwakajairika kwakaenzana nekupokana kukuru uye hazvikanganisi basa rakajairwa rezvimwe midziyo yemagetsi, mumutsara wemheni inopindira inokurumidza kuitisa, iyo mheni ikozvino pfupi-dunhu kune bazi. uye kubudiswa kune zvigadzirwa zvepasi.Iyo SPD nyika inokonzerwa nemheni yakasimba yakananga ikozvino inoputika, uye hapana nguva yekuti SPD inopisa.Saka nei mudziyo wekudzivirira wekuvhiya uchipisa?

Chishandiso chekudzivirira chekudzivirira chave chichishandiswa pamutsetse kwenguva yakareba, uye zvishoma nezvishoma zvichadzikira.Panguva ino, apo midziyo mikuru pamutsara inotanga kushanda, kushandiswa kwe overvoltage kunogadzirwa.Uku kuwedzeredza kwekushanda kunogona kukonzera varistor kuburitsa pfupi-circuit ikozvino.Zvinoenderana neMagetsi ekugadzira kupisa formula, kana kupisa kwasvika pane imwe nhanho, muchengeti wekuvhiya anoburitsa kupisa kwakawanda uye kuita kuti moto upise.Naizvozvo, muchengeti wekudzivirira anopiswa kunze, kazhinji anokonzerwa nepfupi-yedunhu ikozvino.

Nekuda kweizvi, zvinonyatso kutsanangurwa muGB 51348-2019 kuti iyo yekumberi yekudzivirira yekuvhiya inofanirwa kuve yakashongedzerwa yakakosha SPD backup mudziviriri.Kana ipfupi-yedunhu ikozvino ikaitika mumutsara, iyo yekuchengetedza yekuchengetedza inodzivirirwa inokurumidza kubviswa, kuitira kuti mudziviriri wekuvhiya adzivirirwe, nenzira iyi mudziviriri wekuvhiya haatsva.
