Izihlanganisi zokuphepha kwezimayini eziphephile ngaphakathi KTJ152 Isithombe Esivelele

Ama-Couplers okuphepha okumba izimayini aphephile ngokwendalo KTJ152

Incazelo emfushane:

I-KTJ152 Mine Safety Coupler iyithuluzi elibalulekile lokushintsha kusuka ezindaweni eziphephile ukuya kwezingaphephile ngaphakathi kwezinhlelo zokuxhumana zemayini. Isetshenziswa kanye nezingcingo zemayini ezifanelekile eziphephile kanye ne-switchboard noma i-dispatching switchboard enemingcele yokukhipha ehambisana nemingcele yokufaka ye-coupler, inikeza ukuhlukaniswa kokuphepha, ukudluliselwa kwesignali, kanye nesistimu yokuxhumana yokuthumela efanele ukusetshenziswa ngaphansi komhlaba ezimayini zamalahle.

Isingeniso Somkhiqizo

I-KTJ152 mining safety coupler inezindlela ezilandelayo zokusebenzisa:

1. Ihlinzeka ngokuxhumana kukagesi okuthembekile phakathi kwemishini kagesi ehlukahlukene esetshenziswa ezimayini, iqinisekisa isignali eqinile kanye nokudluliswa kwamandla.

2. Ihlukanisa ngempumelelo imithombo yamandla aphezulu eyingozi, ivimbele ukungena kumasekethe aphephile ngokwemvelo futhi iqinisekise ukusebenza okuphephile kwemishini ephephile ngokwemvelo ngaphansi komhlaba.

3. Isebenza njengesixhumi esibonakalayo sokuguqulwa kwesignali, ivumelanisa futhi iguqule amamodeli ezinhlobo ezahlukene kanye namazinga kagesi ukuze kuhlangatshezwane nezidingo zokudluliselwa kwesignali phakathi kwemishini yokumba.

4. Ezinhlelweni zokuxhumana zemayini yamalahle engaphansi komhlaba, kuthuthukisa amandla esignali, kwandise ibanga lokudluliselwa kwesignali, futhi kuqinisekisa ukuxhumana okubushelelezi.

5. Ihlunga amasignali angena kumasekethe aphephile ngokwemvelo, isuse ukuphazamiseka futhi ithuthukise ikhwalithi yesignali.

6. Ivikela imishini yokumba ephephile ngokwemvelo emonakalweni obangelwa yi-transaction over-i-voltage kanye ne-over-ukunyuka kwamanje.

2 Uhlobo Olungavimbeli Ukuqhuma

Umkhiqizo ophephile ngaphakathi ukuze usetshenziswe ekumbeni. Uphawu olungaqhumi: [Ex ib Mb] I.

3 Imininingwane

Isixhumi esingasebenzi esinezindlela ezine.

4 Indlela Yokuxhumana

Izintambo zangaphandle ziyasebenzaixhunyiwe futhi kulula.

Izimo Zemvelo Zokusebenza

a) Izinga lokushisa eliphakathi nendawo: 0°C kuya ku-+40°C;

b) Umswakama ojwayelekile: ≤90% (ku-+25°C);

c) Ingcindezi yomoya: 80kPa kuya ku-106kPa;

d) Indawo engenakho ukudlidliza okukhulu kanye nokushaqeka;

e) Indawo Yokusebenza: Phansi endlini.

Umdwebo Wesilinganiso

Amapharamitha Obuchwepheshe

1 Ibanga Lokuxhumana Ne-Dispatcher

I-coupler ifakwe ngqo kwikhabhinethi ye-dispatcher.

4.2 Ukulahlekelwa Kokudluliselwa

Ukulahleka kokudlulisela kwe-coupler ngayinye akumele kudlule i-2dB.

4.3 Ukulahlekelwa Okuqhubekayo

Ukulahlekelwa kwe-crosstalk phakathi kwanoma yimaphi ama-couplers amabili akumele kube ngaphansi kuka-70dB.

4.4 Izimpawu Zokufaka Nokukhipha

4.4.1 Amapharamitha okufaka angaphephile ngokwendalo

a) I-voltage yokufaka ephezulu ye-DC: ≤60V;

b) Ubuningi bamanje wokufaka we-DC: ≤60mA;

c) I-voltage yokufaka yamanje ephezulu kakhulu: ≤90V;

d) Umthamo wokufaka wamanje okhalayo ophezulu: ≤90mA.

4.4.2 Amapharamitha okukhipha aphephile ngaphakathi

a) I-voltage ephezulu ye-DC evulekile: ≤60V;

b) Umkhawulo wamanje we-DC short-circuit: ≤34mA;

c) I-voltage ephezulu kakhulu yesekethe evulekile yamanje: ≤60V;

d) Umkhawulo ophezulu wamandla okushaya ugesi: ≤38mA.

Ukuxhumana Kwesistimu Yokuxhumana

Uhlelo lokuxhumana lwezimayini luqukethe i-KTJ152 mine safety coupler, ucingo oluzenzakalelayo oluphephile ngokwemvelo, kanye ne-interchange evamile esekelwe emhlabathini noma i-digital program-controlled telephone exchange, njengoba kuboniswe kumdwebo olandelayo.
