Yuye uphawu olubunjiweyo lwetyala umqhekezi izinto zokukhetha

Ngokwesakhiwo sohlelo lwesaphuli sesekethe, kukho uhlobo lwendalo yonke, uhlobo lweplastiki yeqokobhe, i-plastic case circuit breaker, elungele ukulinganisa i-voltage 690V, i-frequency 50/60Hz, ihlelwe ngoku 16 ukuya kwi-1600A inkqubo yokuhambisa okanye njenge-transformer, i-motor. , i-capacitor kunye nezinye izixhobo zokukhusela.Ikakhulu ukusabalalisa amandla ombane, ukwenza isebe kunye nezixhobo zombane zigqithise, isiphaluka esifutshane, indawo yokuvuza kunye nokukhusela ngaphantsi kwe-voltage, ingasetyenziselwa umgca kunye nezixhobo zombane azikho ukuguqulwa rhoqo.Isetyenziswa kakhulu kwishishini kunye nezolimo, ezothutho, imigodi, ukwakhiwa koluntu kunye nokhuselo lwesizwe kunye namanye amasebe, ukuhanjiswa kunye nokuhanjiswa kwamandla, ukulawulwa kwesekethe kunye nokukhuselwa kudlala indima enkulu, kusetyenziso olukhulu, uluhlu olubanzi lweemveliso.Ngenxa yokuba abasebenzisi abaziqondi iimpawu kunye neemfuno zobugcisa ze-MCCB nzulu okanye ngokubanzi, ezinye iikhonsepthi kulula ukubhidaniswa enye kwenye, kwaye kuhlala kukho iimpazamo kunye nokungaqondi kwisicelo esisebenzayo.Iiparamitha ezibalulekileyo ekufuneka umsebenzisi anikele ingqalelo kuzo xa ekhetha kwaye esebenzisa i-MCCB ziziswa ngokweenkcukacha.Ngoku, inkcazo yenqanaba lesakhelo seqokobhe lesakhelo sisetyenziselwa ukunceda umsebenzisi ngokufanelekileyo akhethe ukusebenzisa i-MCCB.

Ibakala lesibiyeli seqhekeza lesekethe

Isakhelo sesakhelo sesakhelo sesekethe sesakhelo sesakhelo sesakhelo sesakhelo sesakhelo sesakhelo somjelo olinganisiweyo wohambo oluphezulu olunokuxhonywa kwisakhelo kunye nezindlu zeplastiki ezinobungakanani obusisiseko obufanayo.

Umlinganiselo olinganisiweyo we-circuit breaker ngumhla okhoyo ukuba uhambo kwi-circuit breaker lunokudlula ixesha elide, eyaziwa ngokuba yi-rate current yohambo lwe-circuit breaker.

Kukho iintlobo ngeentlobo zesakhelo sokukala seqokobhe langoku kuthotho olufanayo, kunye neentlobo ezahlukeneyo zangoku kwiqokobhe lesakhelo sokalisho lwangoku.Ngokomzekelo, kukho i-16A, i-20A, i-25A, i-32A, i-40A, i-50A, i-63A, i-80A kunye ne-100A elinganiselwe ngoku kwi-shell ye-100A kunye nokulinganisa isakhelo;Kukho i-100A, i-125A, i-160A, i-180A, i-200A, i-225A elinganiselwe ngoku kwi-shell ye-225A kunye neklasi yefreyimu.Kukho i-100A elinganiselwe okwangoku kuzo zombini i-100A kunye ne-225A i-bracket bracket grade, kodwa ubukhulu, imilo kunye nomthamo wokuphulwa kwe-breaker circuit yahlukile.Ngoko ke, uhlobo kufuneka luzaliswe ngokupheleleyo xa ukhetha, oko kukuthi, umlinganiselo olinganisiweyo we-breaker circuit ngaphakathi kwinqanaba elilinganisiweyo lebakala elithile le-bracket shell.Ulwahlulo lwangoku olulinganisiweyo lukhethwe ngokwe-coefficient ephambili ye (1.25) : kwelinye icala, ihlangabezana kwaye ihlangabezana neemfuno zobuninzi obulinganisiweyo bangoku besiphaluka kunye namacandelo ombane;Enye yeyokumisela umgangatho, ukuze ufumane okona kulungileyo ukusetyenziswa kocingo kunye nenzuzo yokucubungula.Ngoko ke, amabanga ewabonelela ngawo ngala: 3(6), 8, 10, 12.5, 16,20, 25, 32, 40, 50, 63, 80,100, 125, 160, 200, 250, 315, 400A, njl. yalo mmiselo, xa umthwalo obaliweyo womgca we-90A, i-100A kuphela inkcazo ingakhethwa, ngoko ukusebenza kwayo kokukhusela kuchaphazeleka kwinqanaba elithile.

Ukusetwa kwe-Tripper yangoku kuxa i-tripper ihlengahlengiswa kwixabiso elisebenzayo langoku.Ibhekisela kwi-rerated current Kwi-multiple, ixabiso lesenzo sangoku, umzekelo: i-overcurrent iseti kwi-1.2, 1.3, 5, 10 amaxesha angoku, ibhalwe IR = 1.2In, 1.3In, 5In, 10In, njl. Ngoku ezinye ii-trippers ze-elektroniki, ukugqithiswa kwayo kunye nokulibaziseka kwexesha elide kulinganiswa ngoku kulungelelaniswa, i-current ehlengahlengiswayo, enyanisweni, iseyiyo yangoku, ngowona mzuzu uphezulu onokugqithiswa ixesha elide.

Umlinganiselo osebenzayo osebenzayo ngumsebenzi wangempela we-breaker circuit kwi-voltage ethile yokusebenza xa abafowunelwa abancedisayo (i-accessories) bafakwe.Ikhoyo ngoku yi-3A okanye i-6A, esetyenziselwa ukulawula nokukhusela isiphaluka.
