STUDY OF ELECTRICAL NETWORK OF ILLUMINATION IN THE UNDERGROUND MOUNTAIN WORKINGS

Numerous light sources currently in use in Russia have far differing parameters. Underground mines increasingly more use illuminators with LED lamps. The author has earlier evaluated efficiency of various light sources and described arrangement and operation of illuminators in underground openings.

In accordance with the regulatory documents, mines are to use special design lamps to conform with the specificity and conditions of operation.

Lighting mains are supplied by special lighting transformers, apparatuses and starter units. Application of LED lamps allows great reduction in rated capacity of mine lighting mains, and lower capacity lighting transformers are now in demand.

Mine Electric Equipment Production Plant (PP SHELA), in conformity with the changed terms, in 2014 launched manufacture of lighting equipment models AOSh-0.8, AOSh-1.6, AOSh-2.5 and AOSh-5.0 with the transformers with the rated capacities of 0.8, 1.6, 2.5 and 5.0 kV·A, respectively. It is required to determine basic design parameters of transformers and lighting mains to be supplied from these transformer models.

This article gives calculated data for lighting mains installed in underground openings: loss of voltage in the transformers; loss of voltage in the lighting mains; two-phase and three-phase outgoing cable lines. The obtained relationships are accepted by the manufacture for the use in design of lighting mains for mines.

Keywords
