Circuit for changing connections configuration of securing devices, particularly securing methane fields controlled by means of automatic methanometry, characterized in that it comprises a switching matrix (1) panel, and the inputs of the matrix (1) are connected to a blockade unit (2) of breaking devices (11), which unit is connected to the block (3) signalling the operation state of the breaking devices (11), whereas the outputs of the switching matrix (1) panel are connected in series, via the signalisation block (4) signaling the operation state of the electric fields of the high-tension switching station, to breaker coils (5) situated in particular electric fields of the high-tension switching station, whereas the signalisation blocks (3, 4) and the blockade unit (2) are connected in parallel to a warning signalisation unit (6) whose input is connected to the methanometry central unit (CMM), and the output is connected to warning signalling devices (7).<IMAGE>
