| description | One of the significant problems of modern locomotives is to
ensure their electrical and fire safety. A method is described
that allows to quickly determine the number of the traction
motor in the power circuit, the state of isolation of which
is emergency. The disadvantage of the existing protection
method is that it only provides information about the loss
of insulation integrity in the positive or negative circuit.
The proposed method is based on the use of changes in
electrical capacitance and insulation resistance in the circuit.
The results of mathematical modeling and experimental
research confirm the possibility of practical application of the
breakdown detection device built on the basis of this method.
In the course of the experiments, insulation breakdowns in
the power circuit are successfully localized and emergency
devices to be replaced are found. |
