Abstract
This thesis deals with system design of explosion-proof electrical switchboard for power drive plow kit in coal mines. In the beginning part is given specification mining environment, their distribution and requirements for used machines. Based on these requirements and given parameters supply network with isolated node, this thesis describing and substantiates selection individual components and machines. Onwards this thesis deals dimension of current line. Output of this thesis is an switchboard electrical diagram and calculation of the thermal conditions inside the switchboard.
