Kuisa nzira yesimba rekuwedzera rinosunga
1. Isa chibatiso chemheni yemagetsi mukuwirirana. Nzvimbo yekumisikidza yemuchina wemarasha ndiko kumucheto kwechibatiso kana banga switch (circuit breaker) mukirasi yenzvimbo yekudzidzisa setiraiti. Shandisa maseti mana eM8 epurasitiki yekuwedzera uye kufananidza self-tapping screws. pamadziro.
2. Saizi yekuisa (70 × 180) uye maburi ekuisa anoenderana pane anosunga simba anofanira kuroverwa pamadziro.
3. Batanidza magetsi. Waya mhenyu yechibatiso chemagetsi yakatsvuka, waya isina kwayakarerekera ndeyebhuruu, uye nzvimbo yepakati iBVR6mm2. Multi-strand copper wire, iyo yepasi waya yemuchina wemarasha ndeyero uye yakasvibira, uye nzvimbo yakachinjika iBVR10m m2. Yakasungwa waya yemhangura, kureba kwewaya ishoma pane kana kuenzana ne500mm. Kana muganho uri pasi kana kuti wakaenzana ne500mm, unogona kuwedzerwa zvakakodzera, asi nheyo yekuchengetedza wiring ipfupi sezvinobvira inofanira kuteverwa, uye kona inofanira kuva yakakura kudarika 90 degrees (arc pane yakarurama).
4. Batanidza simba rekupa kune mheni conductor. Imwe mugumo wetambo yekusunga simba yakananga uye yakanyatso crimp kune terminal yemagetsi anosunga. Waya yekugadzika yakabatana kune yakazvimirira gedhi yepasi kana matatu-phase magetsi ekuisa pasi waya inopihwa nechikoro.

Chengetedzo yekuiswa kwesimba rekuwedzera rinosunga
1. Wiring direction
Kana iyo mheni inosunga yakasimwa, iyo yekupinza uye yekubuda zviteshi haifanirwe kunge yakabatana, kana zvisina kudaro, iyo mheni yekudzivirira inokanganisika zvakanyanya, uye kunyangwe kushanda kwakajairika kwemidziyo kuchakanganiswa. Mhedziso yekupinza yemheni inosunga inoenderana neinopararira kutungamira kwemheni wave, ndiko kuti, kuguma kwekuisa kweyekudyisa, uye iyo inobuda yekupedzisira ndeyekudzivirira midziyo.
2. Nzira yekubatanidza
Kune marudzi maviri enzira dze wiring: series yekubatanidza uye parallel connection. Kazhinji, nzira yekubatanidza chete ndiyo inoshandiswa munhevedzano yekubatanidza nzira, uye imwe nzira yekubatanidza inoshandiswa nenzira yakafanana yekubatanidza. Waya isina kwayakarerekera yetambo yemagetsi yakabatana ne "N" wiring gomba resimba reSPD, uye pakupedzisira waya yepasi yakatorwa kubva pa "PE" wiring gomba resimba reSPD rakabatana nemheni yekudzivirira grounding busbar kana mheni yekudzivirira grounding bar. Mukuwedzera, iyo yakaderera-yakayambuka-sectional nzvimbo yekubatanidza waya yemubati wemheni inofanira kuenderana nezvinodiwa zvechirongwa chekudzivirira mheni yenyika.

3. Ground wire connection
Kureba kwekugadzika kwetambo yepasi kunofanirwa kunge kupfupi sezvinobvira, imwe mugumo inofanira kuvharirwa zvakananga kune chigadziko chemusungwa wemheni, uye tambo yepasi inofanira kubatanidzwa kune yakazvimirira ivhu network (yakasarudzika kubva pamagetsi grounding) kana yakabatanidzwa kune tambo yepasi mumagetsi matatu-chikamu magetsi.
4. Nzvimbo yekuisa
Iyo magetsi inosunga mheni inosunga kazhinji inotora nzira yekudzivirira yakagadziridzwa. Isa yekutanga magetsi ekudzivirira mheni mudziyo pane hombe yekugovera magetsi kabati yechivakwa. Kechipiri, isa chechipiri magetsi ekudzivirira mheni mudziyo pane sub-simba rekupa chivakwa uko kune yemagetsi michina. Pamberi pezvigadzirwa zvemagetsi zvakakosha, isa matatu-level simba mheni inosunga, uye panguva imwe chete, iva nechokwadi chokuti hapana zvinhu zvinopisa uye zvinoputika pedyo nekuiswa kudzivirira moto unokonzerwa nemagetsi emagetsi.
5. Kudzima kushanda
Panguva yekuisa, magetsi anofanira kubviswa, uye kushanda kwehupenyu kunorambidzwa zvachose. Usati washanda, multimeter inofanira kushandiswa kuyedza kana mabhazi kana materminal echikamu chimwe nechimwe akadzimwa zvachose.
6. Tarisa wiring
Tarisa uone kana wiring iri kusangana nemumwe. Kana paine kuonana, gadzirisa nekukurumidza kudzivirira pfupi dunhu remidziyo. Mushure mekugadzwa kwechibatiso chemheni kwapera, inofanira kuongororwa nguva dzose kuti uone kana kubatana kwakasununguka. Kana zvikaonekwa kuti mudziyo wekudzivirira mheni hausi kushanda nemazvo kana kukuvadzwa, iyo mheni yekudzivirira yekudzivirira mheni inodzikira, uye inoda kutsiviwa nekukurumidza.

Common parameters of power mheni arrester
1. Nominal voltage Un:
Iyo yakatemerwa voltage yeyakachengetedzwa system inofanana. Mune iyo ruzivo tekinoroji system, iyi parameter inoratidza mhando yemudziviriri inofanirwa kusarudzwa. Inoratidza kukosha kwe rms ye AC kana DC voltage.
2. Rated voltage Uc:
Inogona kuiswa kumagumo akasarudzwa emudziviriri kwenguva yakareba pasina kukonzera shanduko muhunhu hwemudziviriri uye kumisa iyo yakanyanya RMS voltage yechinhu chekudzivirira.
3. Yakatemerwa discharge ikozvino Isn:
Kana yakajairwa mheni wave ine waveform ye8/20μs ikaiswa kune inodzivirira kagumi, iyo yakanyanya kuvhiya ikozvino peak kukosha iyo mudziviriri anogona kumira.
4. Maximum discharge ikozvino Imax:
Kana yakajairwa mheni wave ine waveform ye8/20μs inoiswa kune inodzivirira kamwe chete, iyo yakanyanya kukwira yepamusoro kukosha iyo mudziviriri anogona kumira.
5. Voltage dziviriro level Up:
Iyo yakanyanya kukosha yemudziviriri mune inotevera bvunzo: iyo flashover voltage ine slope ye1KV/μs; iyo yakasara voltage yeyakatemerwa discharge current.
6. Nguva yekupindura tA:
Kunzwa kwechiito uye nguva yekuparara kwechinhu chakakosha chekudzivirira chinonyanya kuratidzwa mumudziviriri chinosiyana mukati meimwe nguva yenguva zvichienderana nekutsetseka kwe du/dt kana di/dt.
7. Data kutapurirana mwero Vs:
Inoratidza kuti mabhii mangani anofambiswa musekondi imwe chete, unit: bps; ndiyo inotaridza kukosha kwekusarudzwa kwakaringana kwemidziyo yekudzivirira mheni muhurongwa hwekutumira data. Iyo data yekufambisa mwero yemidziyo yekudzivirira mheni inoenderana neiyo nzira yekufambisa yehurongwa.
8. Kuisa kurasikirwa Ae:
Chiyero chemagetsi pamberi uye mushure mekuiswa kwemudziviriri pane yakapihwa frequency.
9. Dzosera kurasikirwa Ar:
Iyo inomiririra chikamu cheiyo yekumberi wave inoratidzwa pane yekudzivirira mudziyo (reflection point), uye iri parameter inoyera zvakananga kana mudziyo wekudzivirira uchienderana neiyo system impedance.
10. Maximum longitudinal discharge current:
Inoreva iyo yakanyanya kufundura ikozvino peak kukosha iyo mudziviriri anogona kumira kana yakajairwa mheni wave ine waveform ye8/20μs inoiswa pasi kamwe.
11. Maximum lateral discharge current:
Kana yakajairika mheni wave ine waveform ye8/20μs inoiswa pakati pechigunwe mutsara uye mutsara, iyo yakanyanya surge ikozvino peak kukosha iyo mudziviriri anogona kumira.
12. Online impedance:
Inoreva huwandu hweiyo loop impedance uye inductive reactance inoyerera kuburikidza nemudziviriri pane yezita voltage Un. Kazhinji inonzi "system impedance".
13. Peak discharge current:
Kune marudzi maviri: yakayerwa discharge ikozvino Isn uye yakanyanya kuburitsa ikozvino Imax.
14. Leakage current:
Inoreva iyo DC ikozvino inoyerera kuburikidza nemudziviriri pane inomina voltage Un ye75 kana 80.
