Gwaro reTransformer Electrostatic Shields (E-shields)

Chii chinonzi e-shield?
Nhoo yemagetsi ipepa rakatetepa risingashandise magineti. Nhoo inogona kuva yemhangura kana aruminiyamu. Pepa rakatetepa iri rinoenda pakati pemawinding ekutanga neechipiri etransformer. Pepa riri mucoil yega yega rinobatanidza pamwe chete neconductor imwe chete inobatanidza nechassis yetransformer.

Chii chinoitwa neE-shields mumatransformer?
Ma-e-shields anodzosera kukanganiswa kwemagetsi kunokuvadza kubva pamagetsi etransformer uye magetsi anonzwa ari mumasisitimu emagetsi. Izvi zvinodzivirira transformer nesystem yakabatana nayo.
Ngatitarisei izvi zvakadzama tichitanga nezvinodzivirirwa neE-shields.

Kuderedza kusimba
Mazhinji emagetsi emazuva ano anowanzo kanganiswa nemagetsi anochinja-chinja uye ruzha rwemagetsi. Chidziviriro chemagetsi chakadzika chinoderedza (chinoderedza) kukanganiswa uku.

Mufananidzo uri pamusoro apa uri kuruboshwe unoratidza kukwira kwemagetsi kwenguva pfupi. Rudzi urwu rwekuwedzera kwakanyanya kwemagetsi emagetsi kunobva mumidziyo yehofisi yakafanana nemakombiyuta kana mafotokopi. MaInverter ndiwo anowanzo konzera kukwira kwemagetsi kwenguva pfupi. Mufananidzo uri kurudyi unoratidza muenzaniso weruzha rwemode mudunhu remagetsi. Ruzha rwemode runowanzoitika mumacircuit emagetsi. Masisitimu asina waya zvakanaka ane tambo dzisina kusimba anowanzo tambura neruzha rwemode.
Zvino ngatitarisei kuti E-shield inobata sei nekukanganiswa uku.

Kubatanidza Kunokwanisa
Chivharo cheE chakadzika chinoderedza kubatana kwemagetsi pakati pemawinding ekutanga neechipiri. Pane kubatana nemhepo yechipiri, mhepo yekutanga inobatanidza neE-shield. Chivharo cheE chakadzika chinopa nzira yakaderera yekudzivirira inopinda pasi. Kukanganiswa kwemagetsi kunodzoserwa kure nemhepo yechipiri. Izvi zvinoshandawo kubva kune rimwe divi re transformer (yechipiri kuenda kune yekutanga).

Kuputika kwenguva pfupi uye ruzha rwemode zvinogona kukuvadza matransformer nemimwe michina yemagetsi. Chidziviriro chemagetsi pakati pemagetsi ane voltage yakakwira nemagetsi akaderera chinoderedza njodzi dzakadaro. Chinhu chakakosha pakupa magetsi kumagetsi anonzwa.

Mienzaniso yeTransformers dzinoshandisa E-shield
Matransformer ezuva nemhepo
Kukanganiswa kweHarmonic uye kushanduka kwakakosha kubva kuma solar inverters kunoendeswa ku utility grid. Kukanganiswa kwevoltage uku kunoita kuti pave nemigumisiro yakafanana ne impulse mu HV winding ichipa grid. Kuputika kwevoltage kwenguva pfupi kudivi re utility kunogonawo kupfuudzwa ku inverter. Izvi zviitiko zve overvoltage zvinogona kukuvadza zvikamu zvinonzwa zve inverter. E-shields dzinopa dziviriro kune transformer, grid, uye inverter.
Dzidza zvakawanda nezve saizi ye solar transformer uye zvinodiwa pakugadzira.

Dhiraivha Transformer yekuzviparadzanisas
Matransformer eDrive isolation akavakwa kuti agone kutsungirira kusagadzikana kwemagetsi efrequency (harmonic). Kukanganiswa kwakadaro kunokonzerwa nemidziyo yakaita semamotor drives (kana VFDs). Saka izwi rekuti "drive" muzita racho. Pamusoro peharmonics, mamotor drives anogonawo kuunza kumwe kusagadzikana kwemagetsi (senge ruzha rwemode). Apa ndipo panoshanda E-shield. Matransformer eDrive isolation anosanganisira kanenge E-shield imwe chete pakati peHV neLV coils. Zvishongo zvakawanda zvinogona kushandiswawo. MaE-shields anogona kuiswa pakati pemacoil emukati nemakumbo emukati zvakare.
Mashandisirwo ane voltage disorders (senge transient spikes uye mode noise) anobatsirwa ne transformer ine E-shield. E-shields hadzidhure, uye dzinopa purofiti yakakura pakudyara mari uko matambudziko emhando yemagetsi ari njodzi.
