IMotor Protection Circuit Breaker J3VE
Inombolo yemveliso
Iimpawu zesakhiwo
● Olu luhlu lwezaphuli zesekethe ikakhulu luqulunqwe yindlela, inkqubo yoqhagamshelwano, isixhobo sokukhubeka senkqubo yokucima i-arc, isiseko se-insulating kunye negobolondo.
● Uhlobo lwe-J3VE1 i-breaker circuit breakers luxhotyiswe ngoqhagamshelwano oluncedisayo.I-J3VE3 kunye ne-J3VE4 uhlobo lwe-circuit breakers aluxhotyiswanga ngoonxibelelwano abancedisayo, kodwa banokuxhotyiswa ngezixhobo zoqhagamshelwano ezincedisayo.
● Kukho iindidi ezimbini zohambo kwii-circuit breakers: enye yi-bimetallic inverse time delay trip yokukhusela umthwalo ogqithisileyo;enye yi-electromagnetic trip ekhawulezileyo yokukhusela i-short-circuit.I-breaker circuit nayo inesixhobo sembuyekezo yeqondo lokushisa, ngoko ke iimpawu zokukhusela azichatshazelwa ngubushushu be-ambient.
● I-J3VE1, i-J3VE3 kunye ne-J3VE4 ii-circuit breakers zisebenza ngeqhosha, i-knob kunye nokusingatha ngokulandelanayo.
● I-breaker circuit ifakwe phambi kwebhodi.I-J3VE1, i-J3VE3, i-breaker circuit breakers nayo inekhadi eliqhelekileyo lokunyuka, elinokufakwa ngokuthe ngqo kumzila oqhelekileyo kunye nobubanzi be-35mm (kufuneka ihambisane ne-DINEN50022).
● Inkqubo ye-J3VE3 kunye ne-J3VE4 i-circuit breakers isebenzisa izakhiwo ezikhawulezayo kunye nezikhawulezayo, kunye nezixhobo zabo zokuhamba zineempawu zangoku ezilinganiselweyo, ngoko ke i-circuit breaker inomthamo ophezulu wokuqhawula i-short-circuit.
● Umphambili we-breaker circuit une-pointer yokulungelelanisa i-current yesixhobo sokuhamba, esinokuseta i-tripping current ngaphakathi koluhlu oluchaziweyo.
● I-breaker circuit inokudityaniswa kunye nezixhobo ezifana nokukhululwa kwe-undervoltage, ukukhululwa kwe-shunt, ukukhanya kwesalathisi, ukutshixa, kunye neentlobo ezahlukeneyo zokukhusela izivalo.Nceda ucacise xa u-odola.
