Elektrolitnite kondenzatori

Kondenzatori

Kondenzatori sa elektricheski komponenti, koito sa v osnovata na vsyaka elektricheska veriga. Te predstavlyavat dva elktricheski zaredeni provodnika razdeleni ot dielektrik kato khartiya, plastmasa, stŭklo, vŭzdukh ili drug material, koĭto e slabo provodim. Mezhdu dvata provodnika se sŭzdava pole, v koeto mozhe da se zapazva elektricheska energiya. Tazi zapazena elektricheska energiya mozhe da se izpolzva pri kompensirane na padovete v elektromagnitnoto pole. Kapatsiteta na sŭkhranenata elektricheska energiya se izmerva s mernata edinitsa farad.

Elektrolitnite kondenzatori

Elektrolitnite kondenzatori (aluminievi kondenzatori) sa kondenzatori, v koito ednata ot dvete plastini, izpŭlnyavashti rolyata na anod i katod, e nemetalna substantsiya, narechena elektrolit. Elektrolitnite kondenzatori izpolzvat aluminiĭ ili po-tochno aluminiev oksid vŭrkhu khartiya za dielektrik Tozi tip kondenzatori se sŭstoyat ot dve, naviti na rolki, tŭnki aluminievi folia, ednoto ot koito e pokrito s tŭnŭk sloĭ aluminiev oksid, sluzhesht kato izolatsiya, i zavito v parafinirana khartiya, napoena s elektrolit. Tova predstavlyava anodŭt v kondenzatora. Drugata rolka aluminievo folio zaedno s techniya elektrolit se yavyavat katod. Dvete rolki, zaedno s techniya elektrolit, sa kapsulovani v khermeticheski zatvoren korpus.

Vidove elektrolitni kondenzatori

V zavisimost ot razpolozhenieto na vŭnshnite izvodi, elektrolitnite kondenzatori bivat:

• Aksialni
• Radialni

Elektrolitnite kondenzatori mogat da bŭdat:

• Aluminievi
• Tantalovi

Polyariziran montazh, malŭk razmer s golyam kapatsitet

Po spetsifichnoto za elektrolitnite kondenzatori e malkiyat razmer i vŭpreki tova golemiyat kapatsitet, obem ot zaryad ot energiya, koĭto mozhe da sŭkhranyavat. Tova gi pravi izklyuchitelno udobni za vgrazhdane v elektricheski ustroĭstva kato generatori, zakhranvaniya, adapteri, chestotni regulatori i naĭ-razlichna elektronika i aparatura. Vazhno e da se otbelezhi, che za razlika ot drugite kondenzatori te sa polyarizirani, koeto oznachava, che mogat da se izpolzvat samo v elektricheski sistemi s postoyanen tok. Montazhŭt e strogo spetsifichen i tryabva da se spazva.

Electrolytic capacitors

Capacitors

Capacitors are electrical components that form the basis of any electrical circuit. They are two electrically charged conductors separated by a dielectric such as paper, plastic, glass, air, or other material that is poorly conductive. A field is created between the two wires in which electrical energy can be stored. This conserved electrical energy can be used in compensating for dips in the electromagnetic field. The capacity of the stored electrical energy is measured with the unit farad.

Electrolytic capacitors

Electrolytic capacitors (aluminum capacitors) are capacitors in which one of the two plates acting as anode and cathode is a non-metallic substance called electrolyte. Electrolytic capacitors use aluminum, or more precisely, aluminum oxide on paper for a dielectric. This type of capacitor consists of two rolls of thin aluminum foil, one of which is covered with a thin layer of aluminum oxide as insulation, and wrapped in waxed paper , soaked in electrolyte. This is the anode in the capacitor. The other roll of aluminum foil together with the liquid electrolyte is the cathode. The two rolls, together with the liquid electrolyte, are encapsulated in a hermetically sealed housing.

Types of electrolytic capacitors

Depending on the location of the external terminals, electrolytic capacitors are:

• Axial
• Radial

Electrolytic capacitors can be:

• Aluminum
• Tantalums

Polarized mount, small size with large capacity

What is specific about electrolytic capacitors is their small size and yet large capacity, the volume of energy charge they can store. This makes them extremely convenient for embedding in electrical devices such as generators, power supplies, adapters, frequency regulators and various electronics and equipment. It is important to note that unlike other capacitors, they are polarized, which means they can only be used in direct current electrical systems. Installation is strictly specific and must be followed.
