IziXhobo zoKhuseleko lweMigodi eziKhuselekileyo ngokwendalo KTJ152 Umfanekiso oPhambili

IiCouplers zokhuseleko lwemigodi ezikhuselekileyo ngaphakathi KTJ152

Inkcazo emfutshane:

I-KTJ152 Mine Safety Coupler sisixhobo esibalulekileyo sokutshintsha ukusuka kwiindawo ezikhuselekileyo ukuya kwiindawo ezingakhuselekanga kwiinkqubo zonxibelelwano lwemigodi. Isetyenziswa kunye neefowuni zemigodi ezikhuselekileyo ngokwangaphakathi kunye ne-switchboard okanye i-dispatching switchboard enemilinganiselo yokukhupha efana neeparameter zokufaka ze-coupler, ibonelela ngokwahlulahlula ukhuseleko, ukuhanjiswa kwesignali, kunye nenkqubo yonxibelelwano lokuhambisa efanelekileyo ukusetyenziswa phantsi komhlaba kwimigodi yamalahle.

Intshayelelo yeMveliso

Isixhumi sokhuseleko semigodi ye-KTJ152 sinokusetyenziswa oku kulandelayo:

1. Ibonelela ngonxibelelwano lombane oluthembekileyo phakathi kwezixhobo ezahlukeneyo zombane ezisetyenziswa kwimigodi, iqinisekisa ukuhanjiswa kombane okuzinzileyo kunye nombane.

2. Iyahlula ngempumelelo imithombo yamandla ayingozi, iwathintele ekungeneni kwiisekethe ezikhuselekileyo ngaphakathi kwaye iqinisekise ukusebenza ngokukhuselekileyo kwezixhobo ezikhuselekileyo ngaphantsi komhlaba.

3. Isebenza njengojongano lokuguqula isignali, ihlengahlengisa kwaye iguqula iimodeli zeentlobo ezahlukeneyo kunye namanqanaba ombane ukuze zihlangabezane neemfuno zokudlulisela isignali phakathi kwezixhobo zemigodi.

4. Kwiinkqubo zonxibelelwano zemigodi yamalahle engaphantsi komhlaba, inyusa amandla esignali, yandisa umgama wokudluliselwa kwesignali, kwaye iqinisekisa unxibelelwano oluhamba kakuhle.

5. Ihluza imiqondiso engena kwiisekethe ezikhuselekileyo, isusa ukuphazamiseka kwaye iphucula umgangatho wesignali.

6. Ikhusela izixhobo zokumba ezikhuselekileyo ngokwangaphakathi kumonakalo obangelwa kukudlula kwexesha elifutshane-i-voltage kunye nokugqitha-ukunyuka kwamandla angoku.
