Lisebelisoa tsa ho lemoha phoso ea Arc

Li-arcs ke eng?

Li-arcs ke ho tsoa ha plasma ho bakoang ke motlakase o fetang ka mokhoa o tloaelehileng o sa sebetseng, joalo ka moea.Sena se bakoa ke ha motlakase o kopanya likhase tse moeeng, mocheso o entsoeng ke arcing o ka feta 6000 ° C.Lithempereichara tsena li lekane ho qala mollo.

Ke eng e bakang li-arcs?

Arc e thehoa ha motlakase o tlōla lekhalo pakeng tsa lisebelisoa tse peli tsa conductive.Lisosa tse atileng haholo tsa li-arcs li kenyelletsa, likhokahano tse apereng lisebelisoa tsa motlakase, tšenyo ea ho kenya letsoho, ho robeha ha mohala le likhokahano tse hlephileng, ho bolela tse 'maloa.

Ke hobane'ng ha cable ea ka e ka senyeha 'me ke hobane'ng ha ho ka ba le li-terminations tse hlephileng?

Lisosa tsa ts'enyehelo ea lithapo li fapane haholo, tse ling tsa lisosa tse atileng haholo tsa ts'enyehelo ke: tšenyo ea likhoto, likhoele tse pshatlehang kapa tse qabeletsoeng le ho ts'oaroa hampe le ts'enyo ea ho koala thapo e bakoang ke lipekere kapa likurufu le liboro.

Likhokahano tse hlephileng, joalo ka ha ho boletsoe pejana, li etsahala hangata ka ho felisoa ha screwed, ho na le mabaka a mabeli a mantlha a sena;ea pele e fosahetse tightening ea kamano pele, ka thato ea molemo ka ho fetisisa lefatšeng batho ke batho le ho etsa liphoso.Le ha ho hlahisoa ha li-screwdriver tsa torque lefats'eng la ho kenya motlakase ho ntlafalitse liphoso tsena li ntse li ka etsahala.

Tsela ea bobeli ea ho khaotsa ho hlephileng ho ka etsahala ke ka lebaka la matla a motlakase a motlakase a hlahisoang ke ho phalla ha motlakase ka li-conductor.Matla ana ha nako e ntse e ea a tla etsa hore likhokahano li fokotsehe butle-butle.

Lisebelisoa tsa Arc Fault Detection ke eng?

Li-AFDD ke lisebelisoa tsa ts'ireletso tse kentsoeng litsing tsa bareki ho fana ka tšireletso ho liphoso tsa arc.Ba sebelisa theknoloji ea microprocessor ho sekaseka sebopeho sa motlakase se sebelisoang ho bona li-signature tse sa tloaelehang tse ka bolelang arc potolohong.Sena se tla khaola motlakase ho potoloho e amehileng mme se ka thibela mollo.Li na le kutloelo-bohloko haholo ho li-arcs ho feta lisebelisoa tse tloaelehileng tsa tšireletso ea potoloho.

Na ke hloka ho kenya Arc Fault Detection Devices?

Li-AFDD li bohlokoa ho nahanoa haeba ho na le kotsi e eketsehileng ea mollo, joalo ka:

• Meaho e nang le marobalo, mohlala, matlo, lihotele le lihostele.

• Libaka tse nang le kotsi ea mollo ka lebaka la tlhaho ea thepa e lokiselitsoeng kapa e bolokiloeng, mohlala, mabenkele a thepa e tukang.

• Libaka tse nang le thepa ea kaho e tukang, mohlala meaho ea lepolanka.

• Mehaho ea ho jala mollo, mohlala, meaho ea joang le meaho ea foreimi ea mapolanka.

• Libaka tse kotsing ea thepa e ke keng ea khutlisoa, mohlala, limusiamo, meaho e thathamisitsoeng le lintho tse nang le boleng ba maikutlo.

Na ke hloka ho kenya AFDD potolohong e 'ngoe le e' ngoe?

Maemong a mang, ho ka 'na ha e-ba ho loketseng ho sireletsa lipotoloho tse itseng tsa ho qetela eseng tse ling, empa haeba kotsi e bakoa ke mehaho ea ho jala mollo, mohlala, mohaho o entsoeng ka lepolanka, ho kenngoa hohle ho lokela ho sireletsoa.
