Tataiso ho Transformer Electrostatic Shields (E-thebe)

E-thebe ke eng?

Thebe ea electrostatic ke letlapa le tšesaane le se nang makenete. Thebe e ka ba koporo kapa aluminium. Letlapa lena le tšesaane le tsamaea pakeng tsa transformer's ea pele le ea bobeli windings. Letlapa ka har'a coil e 'ngoe le e' ngoe e hokahana hammoho le conductor e le 'ngoe e tlamahanang le chassis ea transformer.

Li-E-thebe li etsa eng ka li-transformer?

E-Lithebe li tsamaisa litšitiso tse kotsi tsa motlakase hole le transformer's likhoele le lisebelisoa tsa elektroniki tse hlokolosi lits'ebetsong tsa motlakase. Sena se sireletsa transformer le tsamaiso e amanang le eona.

Ha re shebeng sena ka botlalo ho qala ka hore na li-E-thebe li sireletsa khahlanong le eng.

Khatholoho

Li-circuits tse ngata tsa sejoale-joale tsa motlakase li tlas'a li-spikes tsa nakoana le lerata la mode. E-thebe e theohileng e nyenyefatsa (e fokotsa) litšitiso tsena.

Setšoantšo se kaholimo se ka letsohong le letšehali se bonts'a sekhahla sa motlakase oa nakoana. Mofuta ona oa keketseho e matla ea motlakase o hlahisoang ke lisebelisoa tse tloaelehileng tsa ofisi joalo ka likhomphutha kapa likopi. Li-inverters le tsona ke mohloli o tloaelehileng oa li-spikes tsa nakoana. Setšoantšo se ka ho le letona se bontša mohlala oa lerata la mokhoa oa potoloho ea motlakase. Lerata la mode le tloaelehile lipotolohong tsa elektroniki. Litsamaiso tse sa sebetseng hantle tsa lithapo tse sirelelitsoeng ka lithapo tse sa nepahalang hangata li na le lerata la mokhoa.

Joale ha re shebeng hore na E-thebe e sebetsana joang le litšitiso tsena.

Capacitive Coupling

E-thebe e theohileng e fokotsa ho kopana ho matla pakeng tsa mapheo a mathomo le a bobeli. Sebakeng sa ho hokahana le moea oa bobeli, banyalani ba mantlha ba nang le E-thebe. Thebe ea E e thehiloeng e fana ka tsela e tlase ea ho thibela mobu. Litšitiso tsa motlakase li fetisetsoa hole le mapheo a bobeli. Sena se boetse se sebetsa ho tloha pheletsong e 'ngoe ea transformer (ea bobeli ho ea ho ea pele).

Li-spikes tsa nakoana le lerata la mode li ka senya li-transformer le lisebelisoa tse ling tsa motlakase. Thebe ea electrostatic pakeng tsa motlakase o phahameng le likhoele tsa motlakase o tlase e fokotsa likotsi tse joalo. Taba ea bohlokoa ha o fana ka matla ho lisebelisoa tsa elektroniki tse bobebe.

Mehlala ea Transformers e Sebelisang E-thebe

Solar & Wind Transformers

Litšitiso tsa Harmonic le phetoho e khethehileng ea li-inverters tsa letsatsi li fetisetsoa ho grid ea utility. Litšitiso tsena tsa motlakase li baka litlamorao tse ts'oanang le ts'ebetso ea HV e fepa marang-rang. Li-spikes tsa overvoltage tse fetelletseng ka lehlakoreng la lisebelisoa li ka fetela ho inverter. Liketsahalo tsena tsa overvoltage li ka senya inverter's likarolo tse hlokolosi. E-lithebe li fana ka tšireletso bakeng sa transformer, grid le inverter.

Ithute haholoanyane ka boholo ba li-solar transformer sizeng le litlhoko tsa moralo.

Khanna Li-Isolation Transformers

Li-transformer tsa ho itšehla thajana li hahiloe ho mamella litšitiso tse phahameng tsa maqhubu (harmonics). Litšitiso tse joalo li bakoa ke lisebelisoa tse kang li-motor drive (kapa VFDs). Ka hona lentsoekgannaka lebitso. Ntle le li-harmonics, li-drive tsa likoloi li ka hlahisa litšitiso tse ling tsa motlakase (joalo ka lerata la mode). Mona ke moo E-thebe e kenang teng. Li-transformer tsa ho itšehla thajana li kenyelletsa bonyane thebe e le 'ngoe lipakeng tsa HV le LV coil. Ho ka sebelisoa lithebe tse ngata hape. Lithebe tsa E li ka beoa lipakeng tsa likhoele tse kahare le maoto le matsoho.

Lisebelisoa tse nang le mathata a motlakase (joalo ka li-spikes tsa nakoana le lerata la mode) li rua molemo ho transformer e nang le E-shield. Lithebe tsa elektronike li theko e tlaase, 'me li fana ka phaello e kholo ho tsetelong moo litaba tsa boleng ba motlakase li leng kotsi.
