Flameproof mining equipment for transmission and distribution of high, medium and low-voltage devices to identify the arc short circuit

摘要

mining device ognioszczelne to przesylu and chapter high, sredniego and low tension of urzadzeniami to identify short circuit arc has thewith individual insulated chambers (17, 19, 20, 13a) are equipped in suspended to redouble its spikes universal optical sensors swiatlowodowe, laczone modulami pipe (22), swiatlowodowychwhich the individual lived wlu00f3kien swiatlowodowych sa laczone with swiatlowodowymi elements laczacymi.moduly pipe swiatlowodowych (22) pass by hull ognioszczelne (21) into the chamber (18), controlin which there are duplicate and programowo interchangeably dzialajace at least two this impulse measuring opto-electronic electric (25),having each in its construction and architecture field optical measuring moduly shiny swietlnego, obslugujace isolated chambers (17, 19, 20, 13a).
