Zvinonyatsozivikanwa kuti zvigadzirwa zvemagetsi zvinowanzosangana zvisingatarisirwi magetsi ekufamba uye masurges ari mukushandiswa, izvo zvinotungamira mukukuvadzwa kwezvinhu zvemagetsi.Kukuvadzwa kunokonzerwa nemidziyo ye semiconductor muzvigadzirwa zvemagetsi (kusanganisira diode, transistors, SCR uye maseketi akabatanidzwa) ari kupiswa kana kuputswa.

1, imwe yenzira dzekugadzira muchina wese, uye yekumisa system, muchina wese uye system ye (yeruzhinji) uye pasi ichaparadzaniswa, muchina wese uye sisitimu yeimwe neimwe subsystem ichave yakazvimirira yeruzhinji divi, pakati. iyo subsystems kuendesa data kana chiratidzo, inofanirwa kupasi seyero yereferensi, waya yepasi (pamusoro), inofanira kunge iri hombe ikozvino, yakadai semazana akati wandei amperes.

2. Yechipiri nzira yekudzivirira ndeyekutora magetsi emagetsi uye surge yekudzivirira michina muzvikamu zvakakosha zvemuchina wese uye sisitimu (senge komputa kuratidza, nezvimwewo), kuitira kuti magetsi emagetsi uye kuvhiya apfuudzirwe kune subsystem pasi uye. pasi kuburikidza nemidziyo yekudzivirira, kuitira kuti ipfupi voltage uye surge amplitude inopinda mumushini wese uye system inogona kuderedzwa zvakanyanya.

3. Nzira yechitatu yekudzivirira ndeye kushandisa musanganiswa weakati wandei voltage transients uye surge kudzivirira zvishandiso kugadzira multistage kudzivirira wedunhu kune yakakosha uye inodhura michina uye masisitimu.

Surge mudziviriri inopa yakareruka, yehupfumi uye yakavimbika nzira yekudzivirira yesimba rekudzivirira kudzivirira kwemagetsi emidziyo.Kuburikidza nesurge protector (MOV), simba rekuvhiya rinogona kukurumidza kuendeswa kupasi kana mheni ikarova induction uye kushanda yakawandisa, kuitira kuchengetedza mudziyo kubva mukukuvadzwa.

(4) kusimbisa kudzivirira kwemidziyo yemagetsi, musimba rekupa uye mutoro pakati peakateedzana super isolation transformer (inozivikanwawo senzira yekuzviparadzanisa nevamwe), kuitira kuparadzanisa iyo yepamusoro-frequency peak kupindira, asi zvakare inogona kuita yechipiri. equipotential yekubatanidza iri nyore kuita.

Isolation nzira inonyanya kushandisa shanduri yekuzviparadzanisa ine shielding layer.Nekuti common-mode kupindira imhando yekukanganisa kwepasi, inopfuudzwa zvakanyanya kuburikidza nekubatanidza capacitance pakati petransformer windings.Kana shielding layer ikaiswa pakati pekutanga neyechipiri, uye iyo shielding layer yakanyatso kudzika, iyo inopindira voltage inogona kudziviswa kuburikidza nevhavha yekudzivirira, nekudaro ichidzikisa inopindira voltage pane inobuda.

Nechepfungwa, transformer ine shielding layer inogona kuita attenuation inenge 60dB.Asi iyo yekuzviparadzanisa nayo yakanaka kana yakaipa, inowanzoenderana nekudzivirira layer tekinoroji.Zvakanakisa kusarudza 0.2mm gobvu ndiro yemhangura, rutivi rwepakutanga, mutevedzeri wedivi. mumwe nomumwe anowedzera chidziviriro chekudzivirira.Kazhinji, chidziviriro chekutanga chakabatanidzwa kune chechipiri chekudzivirira kuburikidza ne capacitor, iyo inobva yabatanidzwa pasi pechipiri. , uye chidziviriro chekudzivirira chechipiri chechipiri chinogona kubatanidzwa pasi pemucheto.Uye nzvimbo yepamuchinjikwa yenheyo yepasi inofanirawo kuva yakakura.Iyo yega yega transformer ine shielding layer inzira yakanaka, asi vhoriyamu ndiyo. hombe.

Iyi nzira nokuti transformer basa rakanyanya kuroorwa, chiyero chehuwandu, uremu, kugadzika hakusi nyore, pakati uye pasi peak frequency peak uye surge protection effect haina kunaka, saka misika ishoma, vagadziri havana zvakawanda.Saka hazvisizvo. kazhinji inoshandiswa pazviitiko zvakakosha.

(5) kunyura nzira

Absorbing nzira inonyanya kushandisa wave inonzva mudziyo kuti itore kupindira kwemagetsi ekusurge peak. Midziyo inobvisa zvese zvine hunhu hwakafanana, kureva kuti, dzinopa yakakwira impedance pazasi pechikumbaridzo voltage, uye kana magetsi echikumbaridzo adarika, iyo impedance inodonha zvakanyanya, saka. vane imwe inhibitory effect pane peak voltage.

Iyi mhando yemudziyo wekutora inonyanya kusanganisira varistor, gas discharge tube, TVS tube, solid discharge chubhu, etc. Midziyo yakasiyana-siyana inopinza inewo zvayo pakudzvinyirira kwepeak voltage.Kana ikozvino kunyura simba revaristor risina kukura zvakakwana, kumhanya kwekupindura kwechubhu yeamplifaya yegasi inononoka.
