Maitiro Ekuisa Rudzi rwechipiri rweKudzivirira Kukwira: Gwara reNhanho neNhanho

Ndinowanzo nzwa kushushikana kana kukwira kwemagetsi kusingatarisirwi kuchityisidzira kukanganisa michina yakakosha munzvimbo yangu, saka ndinodzidza kuisa chiteshi chakavimbika Chishandiso Chinodzivirira Kukwirazvakava zvakakosha pabasa rangu.

Chidziviriro cheType 2 surge chinoiswa mupaneru huru yemagetsi kuti chivhare overvoltages inodarika nekukurumidza nekuendesa simba rakawandisa kune system yekudzika pasi zvakachengeteka. Chinoderedza kutadza kwemidziyo, chinodzivirira nguva yekushanda, uye chinodzivirira mitoro yemudzimba neyemaindasitiri. Kuisa zvakanaka kunoda maturusi akakodzera, nzira dzakachengeteka dzekubatanidza waya, uye kuyedzwa mushure mekuiswa kuti ive nechokwadi chekudzivirira kwakazara.

Zvino regai ndikutsanangurirei nhanho imwe neimwe kuitira kuti mugone kupedzisa kuisa kwakachengeteka uye kwakavimbika.

Ndezvipi Zvishandiso Zvinodiwa pa Rudzi rwechipiri SPD Kuiswa?

Ndaitya pese pandaivhura panel yekugovera nekuti ndaitya kuti ndaisazove nematurusi akakodzera ekuisa zvakanaka Chishandiso Chinodzivirira Kukwira.

Unoda maturusi anodzivirirwa nemhepo, maPPE akakodzera, midziyo yekukiya-kuburitsa ma tagout, uye maturusi ekuyera emagetsi kuti uise Type 2 SPD zvakachengeteka. Maturusi aya anovimbisa kubvisa waya zvakachengeteka, kusimbisa terminal zvakasimba, kushandisa torque nemazvo, uye kusimbiswa kwevoltage usati waisa waya uye wapedza kuisa waya.

Pandinoisa Type 2 SPD, ndinogara ndichichengeta zvishandiso zvakakwana uye zvakarongeka kuitira kuti ndikwanise kushanda nekukurumidza uye kuderedza zvikanganiso. Ndinoshandisa masikurudhi anodziya nekuti anondipa chivimbo pandinoshanda munzvimbo dzine simba, kunyangwe ndichigara ndichibvisa simba rese panel ndisati ndabata chero chinhu. Ndinogadzirawo magirovhosi, magirazi ekudzivirira, uye zvishandiso zvinovhara maburi nekuti kuchengetedzeka ndiko kwandinonyanya kukoshesa.

Kuti zvikubatsire kuramba wakarongeka, heino runyorwa rwezvishandiso zvandinotevera ini pachangu:

Tafura 1: Zvishandiso Zvakakosha zveKuisa SPD yeRudzi rwechipiri

Pose pandinogadzirira maturusi aya, ndinopedza kuisa nekukurumidza uye zvikanganiso zvewaya zvishoma. Ndinotarisawo torque screwdriver yangu nekuti materminals asina kusimba ndiwo chimwe chezvinhu zvikuru zvinokonzera kukundikana kweSPD. Kuva nezvinhu zvese zvakagadzirira kunondibatsira kuchengetedza mafambiro ebasa, kunyanya pandinoshanda nevatengi vemaindasitiri vanotarisira kufambiswa kwakavimbika nguva dzese.

Ungaisa sei waya zvakachengeteka Rudzi rwechipiri rwekudzivirira kwekuwedzera?

Ndinoyeuka ndichitya kekutanga pandakaisa waya paType 2 SPD nekuti ndaitya kuti kubatana kamwe chete kusina kunaka kwaigona kukuvadza michina pachinzvimbo chekuidzivirira. Asi mushure mekudzidza nzira yakarongeka, kuisa waya kwakava nyore.

Unoisa waya pamudziyo wekudzivirira surge weType 2 nekubatanidza ma terminals ayo kune breaker, neutral terminal kune neutral bar, uye ground terminal kune grounding bar. Mawaya ese anofanira kunge ari mapfupi, akananga, uye akasungirirwa kusvika padanho rakakodzera re torque kuderedza impedance uye kuvandudza mashandiro ekusurge.

Pandinoisa waya paType 2 SPD, chinhu chekutanga chandinoita ndechekuona kuti magetsi abviswa zvachose. Ndinoedza terminal yega yega ne voltage tester nekuti kunyange nyanzvi dzemagetsi dzine ruzivo dzinogona kukanganisa kana vakafunga kuti panel haina simba. Mushure mekusimbisa kuchengetedzeka, ndinoisa mudziyo pedyo ne breaker kuti tambo dzirambe dziri pfupi. Waya pfupi dzinopa SPD nguva yekupindura nekukurumidza uye kupararira kwe surge kuri nani.

Tevere, ndinotevera matanho aya nokungwarira:

1.Batanidza L1, L2, L3 (yezvikamu zvitatu) kana L (yezvikamu chimwe chete)kune munhu akazvipira kuputsa.

2.Batanidza N terminalkune bhaa isina kwayakarerekera kana sisitimu ichiida.

3.Batanidza terminal yePE/Gzvakananga kubhawa rekugadzika.

4.Tarisa kukosha kwetorqueyeterminal yega yega zvichienderana neSPD's datasheet.

5.Nyora zita reSPDkutevedzera mitemo yezvivakwa uye kuongororwa kwemabasa.

Mushure mekuisa waya, ndinoita ongororo yekuona kuti hapana waya dzakayambuka kana kubatana kwakasununguka. Munzvimbo dzemaindasitiri, danho iri rakakosha nekuti kudedera munzvimbo huru kunogona kukonzera kuti materminals asununguke nekufamba kwenguva. Waya pfupi uye yakachena inobatsirawo vaongorori nevashandi vehunyanzvi kunzwisisa kuiswa kwacho nekukurumidza.

Ndezvipi Zvikanganiso Zvaunofanira Kudzivisa Paunenge Uchiisa Type 2 SPDs?

Ndakaita zvikanganiso zvakawanda pakutanga kwebasa rangu nekuti ndaisanzwisisa zvizere kuti SPD inonyanya kukoshesa kunaka kwekuisa. Nekufamba kwenguva, ndakadzidza kuti ndeapi zvikanganiso zvinogona kuderedza zvakanyanya dziviriro yemudziyo.

Zvikanganiso zvinowanzo sanganisira kushandisa tambo refu, kubatanidza waya nehukuru husina kunaka hwe breaker, kuregeredza zvinodiwa ne torque, uye kuisa SPD kure zvakanyanya ne main busbar. Matambudziko aya anowedzera impedance uye anoderedza kugona kweSPD kupinza kana kutungamira simba rekukwira kwemhepo.

Pandinoongorora mapurojekiti kubva kumatekiniki matsva, ndinowanzoona zvikanganiso zvakafanana zvekuisa zvichidzokororwa. Kubata waya kwenguva refu ndiro dambudziko rinowanzoitika nekuti vazhinji vanoisa havanzwisisi kuti kupindira kwetambo kunokanganisa zvakananga mashandiro eSPD. Kukwira kwesimba kunogara kwemasekonzi mashoma, saka kunyangwe zvikanganiso zvidiki zvekubatanidza waya zvinogona kunonoka kudzoserwa kwesimba.

Ndinogara ndichidzidzisa timu yangu mitemo inotevera:

Tafura 2: Zvikanganiso zveKuisa SPD zveRudzi rwechipiri

Nekudzivirira zvikanganiso izvi, ndinounza mhedzisiro inoenderera mberi kune vatengi vemaindasitiri vanovimba nekushanda kwemagetsi kwakasimba. Mafekitori mazhinji anoshandisa michina inokosha zvikuru, saka kusashanda zvakanaka kweSPD kunogona kukonzera kuti hurongwa husashande kwenguva yakareba. Kuisa waya nemazvo uye kuisa pasi zvakanaka kunoita kuti sisitimu igare yakachengeteka uye ichifanotaurwa, izvo chaizvo zvinotarisirwa nevatariri vekutenga vakaita saJeff Weaver pavanoongorora vatengesi.

Unoedza Sei Type 2 SPD Mushure mekuiswa?

Ndinogara ndichinzwa ndakasununguka kana maitiro ekuyedza SPD achiratidza kuti zvese zviri kushanda nemazvo, nekuti kuyedza ndiko humbowo hwekupedzisira hwekuti kuiswa kwacho kwakachengeteka uye kwakagadzirira kushanda kwenguva refu.

Unoedza Type 2 SPD nekusimbisa kuvapo kwevoltage, kutarisa mahwindo echiratidzo, kusimbisa kuenderera mberi kwegrounding, uye kuongorora breaker integrity. Mamwe ma industrial SPD ane remote signaling terminals ayo anofanirawo kuongororwa kuti ave nechokwadi chekuti alarm connection inoshanda nemazvo.

Kuedza kuri nyore kana kwaitwa nemazvo, uye ndinotevera maitiro ekuongorora anowirirana pabasa rega rega:

1.Tarisa hwindo reSPD status(girini = yakanaka, tsvuku = kutsiva).

2.Shandisa multimeterkuti uone kana voltage iri pa breaker iri chaiyo.

3.Yera kuenderera mberi kwepasikuve nechokwadi chekuti impedance yakaderera.

4.Edza ma "terminals" ealarm ari kurekana zvabatanidzwa.

5.Simbisa saizi yemuchina wekubvisa mvura uye mamiriro ekupisamushure mekubatidza.

Kuti maitiro ekuyedza ave akajeka, heino maitiro andinotevera:

Tafura 3: Rudzi rwechipiri rwekuongorora SPD

Kana bvunzo dzese dzapasa, ndinoisa chiratidzo pane imwe nzvimbo uye ndinonyora nezvekuiswa kwayo nekuti izvi zvinobatsira mapoka ekugadzirisa nevanoongorora mune ramangwana. Magwaro akanaka anovaka kuvimba nevatariri vekutenga uye anovimbisa kushandira pamwe kwenguva refu, izvo zvakakosha kumaindasitiri anovimba nekuchengetedzwa kwakasimba kwemafekitori nemidziyo inorema.

Mhedziso

Isa yako Chishandiso Chinodzivirira Kukwiranemidziyo yakakodzera, waya dzakachengeteka, uye bvunzo dzakakodzera kuti uve nechokwadi chekuchengetedzwa kwenguva refu.

Mibvunzo Inowanzo bvunzwa

1. Chii chinonzi Type 2 Surge Protective Device?

Chishandiso chemhando yechipiri cheSPD chinoiswa papaneru huru yemagetsi kudzivirira michina kubva pakupfuura-pfuura kwemagetsi kunokonzerwa nekukwira kwemagetsi kana mheni isina kunanga.

2. Ndinoda here chinhu chinopwanya chirwere cherudzi rwechipiri cheSPD?

Ehe. Chinhu chinopwanya chakagadzirirwa kuchengetedza kubviswa kwesimba panguva yekuwedzerwa kwesimba uye chinodzivirira SPD kubva mumamiriro ezvinhu ekutadza.

3. Rudzi rwechipiri rweSPD runogara kwenguva yakareba sei?

Mazhinji eSPD anogara kwemakore akati wandei, zvichienderana nekuwanda kwemvura, mhando yekuisa, pasi, uye mamiriro ekunze.

4. Ndingaisa Type 2 SPD panze here?

Kwete. Mhando yechipiri yeSPDs yakagadzirirwa kuiswa mukati kunze kwekunge mudziyo wacho wakapihwa mwero wekushandiswa panze.

5. Sei kudzika pasi kwakakosha kune maSPD?

Kuisa pasi kunoita kuti pave nenzira yakaderera yekupindira kwesimba remagetsi, zvichiita kuti simba remagetsi riendeswe kure nemidziyo nekukurumidza uye zvakachengeteka.
