Kalozera wa Transformer Electrostatic Shields (E-shields)

Kodi E-shield ndi chiyani?

Chishango cha electrostatic ndi pepala lochepa kwambiri lopanda maginito. Chishango chikhoza kukhala mkuwa kapena aluminiyamu. Tsamba lopyapyalali limapita pakati pa thiransifoma'ma windings oyambirira ndi sekondale. Pepala mu koyilo iliyonse imalumikizana ndi kondakitala imodzi yomwe imalumikizana ndi chassis ya transformer.

Kodi ma E-shield amatani mu thiransifoma?

E-Zishango zimalozera kusokonezeka kwamagetsi koyipa kutali ndi thiransifoma's ma koyilo ndi zida zamagetsi zamagetsi zamagetsi zamagetsi. Izi zimateteza thiransifoma ndi dongosolo lolumikizidwa nalo.

Tiyeni tiwone izi mwatsatanetsatane kuyambira ndi zomwe E-zishango zimateteza.

Kuchepetsa

Mabwalo ambiri amakono amagetsi amakumana ndi ma spikes osakhalitsa komanso phokoso lanjira. E-chishango chokhazikika chimachepetsera (kuchepetsa) zosokoneza izi.

Chithunzi pamwambapa chakumanzere chikuwonetsa kuchuluka kwamagetsi kwakanthawi kochepa. Kuwonjezeka kwakukulu kotereku kwa magetsi obwera kumabwera chifukwa cha zida zodziwika bwino zamaofesi monga makompyuta kapena ma photocopiers. Ma inverters amakhalanso gwero lambiri la ma spikes osakhalitsa. Chithunzi chomwe chili kumanja chikuwonetsa chitsanzo cha phokoso la mode mumayendedwe amagetsi. Phokoso la mode ndi lofala pamagetsi amagetsi. Makina opanda waya okhala ndi zingwe zotchinga molakwika nthawi zambiri amavutika ndi phokoso lamtundu.

Tsopano tiyeni tiwone momwe E-shield imachitira ndi zosokoneza izi.

Capacitive Coupling

E-shield yokhazikika imachepetsa kulumikizana kwamphamvu pakati pa mafunde a pulayimale ndi achiwiri. M'malo molumikizana ndi mafunde achiwiri, maanja oyamba omangika ndi E-shield. E-chishango chokhazikika chimapereka njira yochepetsera pansi. Kusokonezeka kwamagetsi kumayendetsedwa kutali ndi mafunde achiwiri. Izi zimagwiranso ntchito kuchokera kumalekezero ena a thiransifoma (wachiwiri mpaka pulayimale).

Ma spikes osakhalitsa komanso phokoso lamtundu amatha kuwononga ma transfoma ndi zida zina zamagetsi. Chishango cha electrostatic pakati pa ma voliyumu apamwamba kwambiri ndi ma voliyumu otsika amachepetsa ngozi zotere. Kulingalira kofunikira popereka mphamvu kuzinthu zamagetsi zamagetsi.

Zitsanzo za Transformers Zomwe Zimagwiritsa Ntchito E-shield

Ma Solar & Wind Transformers

Zosokoneza za Harmonic komanso kusintha kwapadera kuchokera ku ma inverter a solar kumasamutsidwa ku gridi yothandiza. Kusokonezeka kwamagetsi uku kumapangitsa zotsatira zowoneka ngati ma HV akuwongolera gridi. Ma spikes a overvoltage osakhalitsa kumbali yogwiritsira ntchito amathanso kupita ku inverter. Zochitika za overvoltage izi zimatha kuwononga inverter's zigawo zikuluzikulu. E-zishango amapereka chitetezo kwa onse thiransifoma, grid, ndi inverter.

Phunzirani zambiri za kukula kwa thiransifoma ya solar komanso kapangidwe kake.

Thamangitsani Zosintha Zodzipatula

Ma transfoma odzipatula amagalimoto amamangidwa kuti athe kupirira kusokonezeka kwamagetsi kwamagetsi (ma harmonics). Zosokoneza zotere zimachitika chifukwa cha zida monga ma drive drive (kapena VFDs). Chifukwa chake mawuyendetsam'dzina. Kuphatikiza pa ma harmonics, ma drive amagalimoto amathanso kuyambitsa kusokonezeka kwina kwamagetsi (monga phokoso lamtundu). Apa ndipamene E-shield imayamba kusewera. Zosinthira zodzipatula pagalimoto zimaphatikizanso chishango chimodzi cha E pakati pa ma koyilo a HV ndi LV. Zishango zingapo zitha kugwiritsidwanso ntchito. Zishango za E-zikhoza kuikidwa pakati pa zozungulira zamkati ndi miyendo yapakati.

Mapulogalamu omwe ali ndi vuto lamagetsi (monga ma spikes osakhalitsa ndi phokoso la mode) amapindula ndi thiransifoma yokhala ndi E-shield. Ma E-zishango ndi otsika mtengo, ndipo amapereka phindu lalikulu pazachuma pomwe nkhani zamtundu wamagetsi ndizowopsa.
