Nyaya dzinoverengeka dzinopisa mune ino yazvino yekudzivirira mudziyo SPD
1. Kupatsanura kwekuyedza waveforms
Yezve yekudzivirira inodzivirira mudziyo SPD bvunzo, kune gakava rinotyisa kumba nekune dzimwe nyika nezvezvikamu zvekuyedza zveClass I (Kirasi B, Type 1), kunyanya panzira yekufananidza yakananga mheni yekumanikidza kubuda, gakava pakati pekomisheni yeIEC neIEEE :
(1) IEC 61643-1, muChikoro I (Kirasi B, Rudzi rwekutanga) yekuwedzera yazvino bvunzo yeiyo yekudzivirira inodzivirira mudziyo, iyo 1 / 10µs waveform ndeyeyedzo waveform.
(2) IEEE C62.45 'IEEE Yakadzika-magetsi ekuchengetedza ekuchengetedza - Chikamu 11 Midziyo yekudzivirira inosunganidzwa kune yakaderera-magetsi magetsi masisitimu - Zvinodikanwa uye nzira dzekuyedza' inotsanangura 8 / 20µs waveform seyedzo waveform.
Vapinduri veiyo 10 / 350µs waveform vanodavira kuti kuitira kuchengetedza 100% panguva yemheni, zviyero zvakakomba zvemheni zvinofanirwa kushandiswa kuyedza zvishandiso zvemheni. Shandisa 10 / 350µs waveform kuona LPS (Mheni Kudzivirirwa Sisitimu) kuona kuti haina kukuvadzwa nemheni. Uye vanotsigira iyo 8 / 20µs waveform vanodavira kuti mushure memakore anopfuura makumi mashanu ekushandisa, iyo waveform inoratidza yakanyanya kwazvo mwero wekubudirira.
Muna Gumiguru 2006, vamiriri vakakodzera veIEC neIEEE vakarongeka uye vakanyora misoro yakati wandei yekutsvaga.

2.Voltage switch mhando uye voltage muganho mhando
Mune iyo yakareba-nhoroondo nhoroondo, iyo voltage inochinja mhando uye nemagetsi kudzora mhando ndiko kusimudzira, kukwikwidza, kuzadzikiswa, hunyanzvi, uye kugadzirisazve. Iyo mweya gap mhando yemagetsi switch switch yakave yakashandiswa zvakanyanya mumakumi emakore apfuura, asi zvakare inofumura zvikanganiso zvakati wandei. Vari:
(1) Chikamu chekutanga (chikamu B) uchishandisa 10 / 350µs spark gap mhando SPD yakakonzera huwandu hwakawanda hwe base base chiteshi chekutaurisa michina marekodhi ekukuvara kukuru kwemheni.
(2) Nekuda kwenguva refu yekupindura kwekuparadzanisa SPD kune mheni, kana chiteshi chengarava chine checheche SPD chete, uye hapana imwe SPD inoshandiswa kune yechipiri nhanho (nhanho C) dziviriro, mheni iripo ingakonzeresa mheni zvishandiso mukukuvara kwechigadzirwa.
(3) Kana chiteshi chengarava chikashandisa B uye C maviri-nhanho chengetedzo, iyo gwanza re SDP's inononoka kupindura nguva kune mheni inogona kukonzera kuti magetsi ese emheni apfuure neC-level voltage-inodzora mudziviriri, zvichikonzera C-chikamu dziviriro kuva kukuvadzwa nemheni.
(4) Panogona kunge paine nzvimbo isingaone yekupararira kwesimba pakati pesimba rekudyidzana pakati peiyo mhando yemhando uye iyo inomanikidza-inomira mhando (bofu poindi zvinoreva kuti hapana kuburitswa kwesarke mukubuda kwesaraki gwanza), zvichizoguma neparaki gwanza rudzi SPD kusaita, uye yechipiri nhanho (nhanho C) dziviriro inoda kumira pamusoro. Mheni yazvino yakaita kuti C-level mudziviriri akanganisike nemheni (yakaganhurirwa nenzvimbo yechiteshi chechiteshi, kureba kwakadzika pakati pematanda maviri SPD kunoda anenge gumi nemashanu metres). Naizvozvo, hazvigoneke padanho rekutanga kutora gap mhando SPD kuti inyatso shandira pamwe neC level SPD.
(5) Iyo inductance yakabatana mune akateedzana pakati pematanho maviri ekudzivirira kuti agadzire dhizaini yekubvisa kugadzirisa dambudziko renzvimbo yekudzivirira pakati pematanho maviri ePSD. Panogona kunge paine nzvimbo isingaone kana dambudziko rekuratidzira pakati pezviviri. Maererano nesumo: "Inductance inoshandiswa sechinhu chinoderedza uye chimiro chemafungu Chimiro chine hukama hwepedyo. Kwemarefu hafu-kukosha waveforms (senge 10 / 350µs), iyo inductor yekumisikidza mhedzisiro haina kunyatsoita (iyo spark gap mhando pamwe inductor haigone kusangana nezvinodzivirirwa zvemarudzi akasiyana emheni kana mheni yarova). Pakudya zvinhu, nguva yekukwira uye kukosha kwepamusoro kwemhepo yekuwedzera inofanirwa kutariswa. ” Zvakare, kunyangwe iyo inductance ikawedzerwa, dambudziko reiyo gap mhando SPD magetsi anosvika angangoita 4kV haigone kugadziriswa, uye mashandiro emunda anoratidza kuti mushure meiyo gap mhando SPD uye gap musanganiswa mhando SPD dzakabatana mune dzakateedzana, iyo C- nhanho 40kA module yakaiswa mukati memagetsi ekuchinja inoshaya iyo SPD Kune akawanda marekodhi ekuparadzwa nemheni.
(6) Iyo di / dt uye du / dt kukosha kweiyo gap-mhando SPD yakakura kwazvo. Iko kukanganisa kwezvinhu zve semiconductor mukati memidziyo yakachengetedzwa kuseri kweyekutanga-chikamu SPD inonyanya kuoneka.
(7) Spark gap SPD isina kuora chiratidzo chiratidzo chebasa
(8) Iyo spark spark mhando SPD haigone kuona mashandiro ekukuvadza alarm uye kukanganisa kure kure chiratidzo (parizvino inogona kungoonekwa ne LED kuratidza mamiriro ekushanda wedunhu rayo rinobatsira, uye hairatidze kuora nekukuvara kwemheni mudziviriri), saka zviripo kune zviteshi zvisina kuchengetedzwa, zviteshi zvePSD hazvigone kunyatsoshandiswa.
Mukupfupisa: kubva pakuona kwema parameter, zviratidzi, uye zvinoshanda zvinhu sekusara kwekumanikidza, kuremedza kureba, gasi remoto, nguva yekupindura, hapana alarm yekukuvara, uye isina-kukanganisa kure kure chiratidzo, kushandiswa kwespark gap SPD munzvimbo yepasi inotyisidzira kushanda kwakachengeteka kwenzira yekutaurirana Nyaya.
Zvisinei, nekuenderera mberi kwekugadzirwa kwetekinoroji, iyo spark gap-yerudzi SPD inoenderera ichikunda yayo pachezvayo zvikanganiso, kushandiswa kwerudzi urwu rweSPD kunoratidzirawo makuru mabhenefiti. Mumakore gumi nemashanu apfuura, kutsvagisa kwakawanda uye kusimudzira kwakaitwa pamhando yemhepo (ona Tafura 15):
Panyaya yekuita, chizvarwa chitsva chezvigadzirwa chine zvakanakira yakaderera masara emagetsi, yakakura kuyerera kugona, uye saizi diki. Kubudikidza nekushandiswa kweiyo micro-gap trigger tekinoroji, inogona kuona iyo "0" chinhambwe chinowirirana neiyo yekumanikidza-inodzora SPD uye mubatanidzwa wekumanikidza-kudzora SPD. Iyo zvakare inobhadharira kushomeka kwayo kwekuteerera uye inonyatsogadzirisa kugadzirwa kwemagetsi ekudzivirira masisitimu. Panyaya yekushanda, chizvarwa chitsva chezvigadzirwa chinogona kuvimbisa kushanda kwakachengeteka kwechigadzirwa chose nekutarisa mashandiro etraki redunhu. Chishandiso chekudzimisa dhizaini chakaiswa mukati meichi chigadzirwa kudzivisa kupisa kweiyo yekunze goko; tekinoroji yakakura yekuvhura daro inogamuchirwa muiyo electrode yakagadzirirwa kudzivirira kuerera kunoenderera mushure mekuyambuka zero. Panguva imwecheteyo, inogona zvakare kupa iri kure chiratidzo chearamu basa kusarudza saizi yakaenzana yemheni mheni, uye kuwedzera hupenyu hwebasa.
