(4) I-voltage yoqhagamshelwano. Xa unxibelelwano lombane luvaliwe, umsinga othile womthwalo usetyenziswa kwisekethe yoqhagamshelwano lombane kunye nexabiso le-voltage phakathi kwabafowunelwa. (5) Ubomi bombane. Xa i-voltage elinganisiweyo isetyenziswa kuzo zombini iziphelo ze-relay driving coil kwaye umthwalo we-resistive olinganisiweyo usetyenziswa kwi-contact loop, umjikelo ungaphantsi kwezihlandlo ezingama-300 ngeyure kwaye umjikelo womsebenzi yi-1∶4, amaxesha okusebenza athembekileyo e-relay. (6) Umthamo womthwalo ogqithisileyo. Xa i-voltage elinganisiweyo isetyenziswa kuzo zombini iziphelo ze-relay driving coil kwaye amaxesha ali-1.5 omthwalo olinganisiweyo usetyenziswa kwi-contact loop, amaxesha okusebenza athembekileyo e-relay anokufezekiswa kwi-operation frequency yamaxesha (10±1)/min [7]. Iintlobo, umzekelo,, iintlobo ezininzi ezahlukeneyo ze-relay, zinokwahlulwa ngesantya se-input voltage relay, i-current relay, i-time relay, i-relay, i-pressure relay, njl.njl., ngokwemigaqo yomsebenzi zinokwahlulwa zibe yi-electromagnetic relay, i-induction type relay, i-electric relay, i-electronic relay, njl.njl., ngokwenjongo zinokwahlulwa zibe yi-control relay, i-relay protection, njl.njl., Ngokwe-input variable form zinokwahlulwa zibe yi-relay kunye ne-measurement relay. [8] Nokuba i-relay isekelwe kubukho okanye ukungabikho kwe-input, i-relay ayisebenzi xa kungekho input, i-relay action xa kukho input, njenge-relay ephakathi, i-relay eqhelekileyo, i-time relay, njl. [8] Ukulinganisa i-relay kusekelwe kutshintsho lwe-input, i-input ihlala ikhona xa isebenza, kuphela xa i-input ifikelela kwixabiso elithile le-relay iya kusebenza, njenge-current relay, i-voltage relay, i-thermal relay, i-speed relay, i-pressure relay, i-liquid level relay, njl. [8] I-electromagnetic relay Umzobo weskimu wesakhiwo se-electromagnetic relay Uninzi lwee-relay ezisetyenziswa kwiisekethe zolawulo zii-electromagnetic relay. I-electromagnetic relay ineempawu zesakhiwo esilula, ixabiso eliphantsi, ukusebenza okulula kunye nokugcinwa, umthamo omncinci woqhagamshelwano (ngokubanzi ngaphantsi kwe-SA), inani elikhulu labafowunelwa kwaye akukho main points kunye nabancedisi, akukho arc extinguishing device, ubungakanani obuncinci, isenzo esikhawulezayo nesichanekileyo, ulawulo olunovelwano, oluthembekileyo, njalo njalo. Isetyenziswa kakhulu kwinkqubo yolawulo lwe-low-voltage. Ii-relay ze-electromagnetic ezisetyenziswa rhoqo ziquka ii-current relay, ii-voltage relay, ii-intermediate relay kunye nee-relay ezincinci ezahlukeneyo. [8]Isakhiwo se-electromagnetic relay kunye nomgaqo wokusebenza ufana ne-contactor, ikakhulu eyenziwe yindlela ye-electromagnetic kunye noqhagamshelwano. Ii-electromagnetic relay zine-DC kunye ne-AC. I-voltage okanye i-current yongezwa kuzo zombini iziphelo ze-coil ukuvelisa amandla e-electromagnetic. Xa amandla e-electromagnetic engaphezulu kwamandla e-spring reaction, i-armature itsalwa ukwenza oonxibelelwano abavulelekileyo nabavalelekileyo bahambe. Xa i-voltage okanye i-current ye-coil iwela okanye inyamalala, i-armature iyakhululwa kwaye unxibelelwano lusetwa kwakhona. [8] I-Thermal relay I-Thermal relay isetyenziselwa kakhulu ukhuseleko lokugqithisa izixhobo zombane (ngokuyintloko i-motor). I-Thermal relay luhlobo lomsebenzi olusebenzisa umgaqo wokufudumeza wangoku wezixhobo zombane, ikufutshane ne-motor vumela iimpawu zokugqithisa zeempawu zexesha elichaseneyo, ikakhulu zisetyenziswa kunye ne-contactor, esetyenziselwa ukugqithisa kwe-motor ye-asynchronous yesigaba sesithathu kunye nokukhuselwa kokungaphumeleli kwesigaba se-motor yesigaba sesithathu kwintsebenzo yokwenyani, zihlala zijongene nazo ezibangelwa zizizathu zombane okanye zoomatshini ezifana nokunyuka kombane, ukugqithisa kunye nokusilela kwesigaba). Ukuba ukugqithisa kombane akukubi, ixesha lifutshane, kwaye ii-windings azidluli ukunyuka kobushushu okuvumelekileyo, oku kungaphezulu kombane kuvumelekile; Ukuba i-over-current inzima kwaye ihlala ixesha elide, iya kukhawulezisa ukuguga kwe-insulation yemoto kwaye itshise nemoto. Ke ngoko, isixhobo sokukhusela i-motor kufuneka sibekwe kwisekethe ye-motor. Kukho iintlobo ezininzi zezixhobo zokukhusela i-motor ezisetyenziswa rhoqo, kwaye ezona zixhaphakileyo yi-metal plate thermal relay. i-metal plate type thermal relay yi-three-phase, kukho iintlobo ezimbini ezinokhuseleko lwe-phase break kunye nezingenalo. [8]I-Time relay Ixesha le-relay lisetyenziselwa ulawulo lwexesha kwisekethe yokulawula. Uhlobo lwayo lukhulu kakhulu, ngokwemigaqo yesenzo sayo lunokwahlulwa lube luhlobo lwe-electromagnetic, uhlobo lwe-air damping, uhlobo lombane kunye nohlobo lwe-elektroniki, ngokwendlela yokulibaziseka lunokwahlulwa lube kukulibaziseka kwamandla kunye nokulibaziseka kwamandla. I-air damping time relay isebenzisa umgaqo we-air damping ukufumana ukulibaziseka kwexesha, okwakhiwa yindlela ye-electromagnetic, indlela yokulibaziseka kunye nenkqubo yoqhagamshelwano. Indlela ye-electromagnetic isebenza ngokuthe ngqo kabini uhlobo lwentsimbi ye-E, inkqubo yoqhagamshelwano isebenzisa i-I-X5 micro switch, kwaye indlela yokulibaziseka isebenzisa i-airbag damper.
