Iimpazamo eziqhelekileyo kunye nokugcinwa kwe-furnace ye-muffle ephezulu

I-1) Emva kokuba umbane wokutshintsha kwesithando somlilo esiphezulu se-muffle sivuliwe, ukukhanya kwesalathisi semitha ye-101 kuvuliwe kwaye i-relay ivuliwe, kodwa kutheni i-furnace ye-muffle ye-furnace ingatshisi? Indlela yokujongana nayo?

Oku kubonisa ukuba amandla e-AC afakwe kwi-loop yocingo lomlilo. Kodwa i-loop ayixhunyiwe kwaye akukho mbane wokufudumeza. Ngokusekelwe kule nto, kunokuchazwa ukuba ucingo lwesithando somlilo okanye i-fuse ivuthelwe. Emva kokujonga nge-multimeter, buyisela ucingo lwesithando somlilo okanye i-fuse. Kufuneka kuqatshelwe apha ukuba kwiimeko ezininzi, iintambo zocingo zomlilo zingatshiswa.

2) Emva kokuba umbane wokutshintsha kwesithando somlilo esiphezulu se-muffle sivaliwe, ukukhanya kwesalathisi semitha ye-101 kuvuliwe, kodwa i-relay ayiguquki (isandi sokuvula asiviwa) okanye i-thyristor ayiqhubeki. Siyintoni isizathu?

Kukho izizathu ezibini zale ngxaki. Enye kukuba unikezelo lwamandla alusetyenziswanga kwikhoyili ye-relay okanye ipali yokulawula ye-thyristor; enye kukuba i-coil relay ivuliwe okanye i-thyristor yonakaliswe; ngoko. Fumana unobangela wempazamo kule miba ilandelayo :

(1) Ukuhanjiswa kwe-DC ngaphakathi kwi-101 yeemitha akudityaniswanga kakuhle ngenxa yokusetyenziswa kwexesha elide;

(2) Ikhoyili ye-relay ivuliwe okanye ipali yokulawula ye-SCR yonakaliswe;

(3) Ucingo okanye umdibaniso ukusuka kwimitha ye-101 ukuya kwi-relay okanye i-thyristor ivuliwe. Emva kokujonga la manqaku angentla, gcoba abafowunelwa ngelaphu le-emery okanye utshintshe i-relay okanye i-thyristor.
