Okujwayelekile

I-YCM7YV uchungechunge lwe-electronic plastic case circuit breaker (ngemuva kwalokhu ebizwa ngokuthi: i-circuit breaker) ifanele amagridi amandla ane-voltage ephansi ane-AC 50Hz, i-voltage engu-insulation elinganiselwe engu-800V, i-voltage yokusebenza elinganiselwe engu-400V nangaphansi, futhi ikalwe ukusebenza kwamanje kufika ku-800A. I-circuit breaker inomkhawulo wesikhathi ophambene wokulibaziseka ogcwele kakhulu wokulibaziseka, umkhawulo wesikhathi esiphambene nesekhethi esifushane, ukubambezeleka okufushane komkhawulo wesikhathi esinqunyiwe, imisebenzi yokuvikela isiyingi esifushane ngokushesha kanye nemisebenzi yokuvikela i-voltage engaphansi. Ngaphansi kwezimo ezijwayelekile, isifunda

i-breaker isetshenziselwa ukushintsha okungajwayelekile kwamasekhethi kanye nokuqala okungajwayelekile

ama-motors.Lolu chungechunge lwama-circuit breaker lunomsebenzi wokuzihlukanisa, futhi uphawu lwalo oluhambisanayo luthi "   "

Izinga: IEC60947-2.

Izimo zokusebenza

1. Izinga lokushisa lomoya elizungezile

a)Inani eliphezulu lomkhawulo aweqeli +40℃;

b)Inani eliphansi lomkhawulo aweqi -5℃;

c)Inani elimaphakathi elingaphezu kwamahora angama-24 alidluli +35℃;

2. Ukuphakama

Ukuphakama kwendawo yokufaka akudluli ku-2000m.

3. Izimo zomoya

Umswakama ohlobene womkhathi aweqi ku-50% lapho i-ambient

izinga lokushisa eliphezulu ngu +40 ° C; ingaba nomswakama ophezulu oyisihlobo endaweni ephansi

amazinga okushisa; lapho isilinganiso sanyanga zonke esiphansi sokushisa esimanzi kakhulu

Inyanga ingu-+25°C, izinga lokushisa elijwayelekile lenyanga eliphezulu ngu +25°C. Umswakama ohlobene ungama-90%, kucatshangelwa ukufingqa okwenzeka endaweni

indawo yomkhiqizo ngenxa yokushintsha kwezinga lokushisa.

4. Iziqu zokungcola

I-pollution degree 3, izesekeli ezifakwe ku-circuit breaker zine-pollution degree 2.

5. Isigaba sokufakwa

Isekhethi eyinhloko ye-circuit breaker izoba isigaba sokufakwa kwe-III, futhi isifunda esisizayo kanye nesekhethi yokulawula kuzoba isigaba sokufaka II.

6. Izimo zokufaka.

Ama-breaker circuit ngokuvamile kufanele afakwe aqonde phezulu, ngokuvamile anezintambo ezibheke phezulu, futhi indawo kazibuthe yangaphandle endaweni yokufaka akufanele idlule izikhathi ezi-5 kunenkundla ye-geomagnetic kunoma iyiphi indlela.
