Ese nshobora gukoresha ferrules zifite screw terminal blocks?

Yego. Ingufu zituma ibyuma bihagarika ibyuma bidafite aho bibohera kandi zikarinda ko imigozi ihagarara. Uburyo bwo gufunga ibyuma mu bice byinshi bya 5.0mm bugenewe kwakira ingufu zidafite aho zibohera nta guhindura. Ingano y'umurambararo w'ingufu igomba kuba ihuye n'urwego rw'insinga z'icyuma.

Kuki terminal block yanjye ishyushye kuri 80A mu gihe ifite amanota 150A?

Igipimo cya 150A gifata ibintu byihariye: ikirere cya 40°C, gushyiraho ahantu hamwe, na torque ikwiye. Iyo agace kuzuye, ikirere kiri hejuru, cyangwa torque itari yo, ubushobozi nyabwo buragabanuka. Pima ubushyuhe ukoresheje thermocouple aho ihurira. Niba irenga 45°C hejuru y’ikirere, banza usuzume imiterere y’aho ishyirwa mbere yo gushinja ibicuruzwa.

Ese nkeneye icyemezo cy’ubugira kabiri kugira ngo noherezwe muri Megizike?

Megizike yemera amahame ya NOM ndetse n'ay'isi yose. Ku bikoresho by'inganda, icyemezo cya NOM kirakenewe, ariko icyuma gifata amashanyarazi gifite ikimenyetso cya UL gishobora gukoreshwa nk'igice cyemewe mu ihuriro ryemewe na NOM. Ibisabwa byihariye biterwa n'icyiciro cy'ibicuruzwa bya nyuma. Saba ikigo cy'iyemezabuguzi cyo mu gace utuyemo kugira ngo ubone ubuyobozi buhamye.

Ni iyihe screwdriver ya torque nkwiye gukoresha kuri 5.0mm pitch terminal blocks?

Skurovideri ifite torque ingana ifite urwego rwa 0.1 kugeza 1.0 Nm irakwiye. Ibipimo bisanzwe ni 0.5 kugeza 0.8 Nm. Ntugakoreshe power driver ifite slip clutch keretse iyo clutch ingana kandi ikemezwa, kuko vibration iva kuri driver ishobora kurekura terminals zegeranye.

Imbonerahamwe y'ibicuruzwa

Ibice bya terminal bivugwa muri iyi nkuru biraboneka muri Ningbo J-Guang Electronics. Igice cy'icyuma cya PCB 301-5.0 Uruhererekane rufite umuvuduko wa 5.0mm, ubushobozi bwa 150A, n'aho icyuma gifunga ibyuma bikoreshwa mu gukwirakwiza ingufu mu nganda. Kugira ngo ubone ubwoko bwose bw'ibicuruzwa, harimo n'ubundi buryo bwo gukwirakwiza ingufu n'amanota y'amashanyarazi, sura urubuga rwa interineti rwa katalogu y'ibicuruzwa.
