Ukushintsha kwe-Solenoid
Uma isiqalisi singasebenzi, izizathu zingase zibe ibhethri elilahliwe, isifunda esivulekile kugesi wokuqala, noma ukuwohloka kwesiqalisi ngokwaso.
Enye yezindawo zokuqala ohlwini lokugcina ukwehluleka kwe-electromagnetic switch, ebaluleke kakhulu 
indima enqubweni yokuqala yokuqalisa. Lapho ukhiye ekushintsheni kokuthungela uphendulelwa endaweni eyedlulele, yamanje igeleza emawindini ka-electromagnetic afakwe kusiqalisi seswishi ye-electromagnetic, futhi inkambu kazibuthe ekhiqiziwe inyakazisa umongo, okuthi, ngosizo lwe-lever, ihambise igiya eduze kwe-rotor shaft futhi ihlanganyele negiya leringi ye-flywheel. Lapho igiya lisebenza ngokugcwele ne-flywheel rim, umgogodla we-electromagnet uvala othintana nabo abakhulu besiqalisi bese uyishayela. Lo mgomo wokusebenza kwe-electromagnetic circuit breaker uholela ekuhlulekeni okubili okujwayelekile.
Esokuqala siphathelene nomonakalo wokusonga kwama-electromagnetic breaker. Lokhu kubonakala ngokungabi bikho kwanoma yikuphi ukusabela kusiqalisi uma sivuliwe. Isizathu sesibili yizinqubo ze-thermoelectric ezihambisana nokuvalwa nokuvulwa koxhumana nabo, ikakhulukazi labo lapho, njengasekuqaleni, kugeleza okwamanje ngamandla amakhulu. Ukukhishwa okulimazayo ngendlela yezinhlansi kwenzeka koxhumana nabo. Babangela i-pitting kanye nokukhuphuka. Izindawo zokuxhumana kancane kancane zilahlekelwa ukuthintana kuze kube yilapho, ekugcineni, ziyeka ngokuphelele ukuqhuba okwamanje. Uma lokhu kwenzeka, ingqikithi kazibuthe kagesi okwenza othintana nabo abanjalo ngeke kubangele ukugeleza kwamanje. Kulokhu, ngemuva kokuguqula ukhiye ekushintsheni kokushisa endaweni ephakeme kakhulu, kuzozwakala ukuchofoza okukodwa kuphela kwegiya le-meshing elinerimu ye-flywheel.
Ukushintsha iswishi ye-solenoid eyonakele ngokuvamile kudinga ukususwa kwayo yonke isiqalo, futhi ngezinye izikhathi ukuhlakazeka kwayo ingxenye. Kwenzeka ukuthi ukuhlinzwa esikhundleni kungenziwa emotweni ngaphandle kokukhipha isiqalisi. Esimeni lapho othintana naye ehlulekile ekushintsheni okungajwayelekile futhi, ngaphezu kwalokho, akukho okwangempela noma okubambele emakethe, kusala kuphela ukuqaqa indlu yokushintsha, ukugaya othintana nabo futhi bayihlanganise ngokuphelele.
