Isu tinoziva kuti iyo yekubatanidza relay inofanirwa kuve ine hutsinye kupfuura iyo general Mosfet, iyo relay mutoro wakakura kupfuura Mosfet.

Yakajairwa DC inotakura mota mota, DC clutch uye DC solenoid mavharuvhu, aya ekufunga mutoro switch akavharwa, mazana kana kunyange zviuru zvemavolts ekumashure emagetsi emagetsi anokonzerwa nekuvhiya achabata hupenyu kuderedza kana kukuvara zvachose.Zvechokwadi kana yazvino idiki, senge kana pedyo 1a, musana electromotive simba kuchaita arc discharge discharge kuchaita kuti kusvibiswa kusangana kwesimbi oxides, izvo zvakaita kuti kukundikana kuonana, kuonana kuramba inova huru.

Pano kutaura, iyo relay inogara ichitadza, isu tinodzivirira, kunyanya tinoda kuwedzera nguva yekushandiswa kweiyo relay, nekuti vanobatika vanogaroita kabhoni deposition, kuchembera, nzvimbo yayo sepakutanga seyakachena.Iko kusangana kwekupokana kuchawedzera nekukurumidza kana hupenyu hwekudzosera hwave pedyo nekumagumo kweiyo relay.

General pasi peyakajairika tembiricha uye kumanikidzwa, mhepo kiyi dielectric breakdown voltage ndeye 200 ~ 300V.saka chinangwa chedu paruzhinji ndechekudzora voltage pazasi 200V kana diki voltage.

Diode yakajairwa inogona kuwedzera zvakanyanya nguva yekudonha, yakajairika diode uye zener diode akateedzana uye kwete yakawandisa pesvedzero pane reverse nguva.Kana iri inductive load.Kana iwo mabikirwo akaparadzana, akareba kudzosera nguva yakareba arcing nguva, uye achapfupisa hupenyu hwesevhisi yekuonana.Semuenzaniso, relay yakabatana kune diode pane coil inoda 9.8ms nguva yekuburitsa vanobatika.Iyo zener diode uye diki chiratidzo diode pamwe chete, inogona kupfupikiswa kusvika 1.9ms.Iyo coil haina kubatana kune diode reverse time relay 1.5ms.

Kunyange zvazvo inductive mutoro wakaoma kubata pane resistive load, kushandiswa kwekudzivirira kwakanaka kuchaita kuti kushanda kuve nani.

Pane nzira mbiri dzekuve dzakaipa kwazvo, usashandise iyo.

Pasi peDC mutoro, high frequency switch inogona kukonzera abnormal high corrosion (electric spark).

Kana iyo yepamusoro frequency inodzora DC solenoid vharafu kana clutch, mabatiro anogona kuitika bhuruu-girinhi corrosion.Zvikonzero zvemamiriro ezvinhu aya apo inogadzirwa ne EDM (electrical arc discharge), nitrogen uye oksijeni mumhepo mumhinduro yakagadzirwa.

Material transfer phenomenon

Kana zvinhu zvacho zvasangana, shanduko inoitika kana chikamu chekusangana chanyungudutswa kana kukuvadzwa.Nekufambiswa kwekufamba kwenguva, uye kunyangwe chiitiko chichaonekwa pazasi.Mushure menguva yakati rebei, kushamwaridzana kusina kuenzana kunonamatira pamwechete.

Iyo mutoro unowanzoitika mune yakakura ikozvino (capacitive uye inductive) inrush ikozvino, iyo arc inogadzirwa inokonzeresa inonamira chiitiko.

Kune anonamira uye maviri chete mazano:

Bata yekudzivirira yedunhu uye zvinhu zvekufambisa zvinhu zvakaita sesirivha, tin oxide, sirivheri tungsten kana AgCu mukushandiswa kwevanobatika.

Kazhinji chimiro che concave chinoonekwa mu cathode, chimiro che convex chinoonekwa mune anode.
