description The invention belongs to the railway locomotive field and relates to a traction loop resistance-capacitance protection resistor over-current detection device for a railway locomotive. The objective of the invention is to solve the problem of potential safety hazards existing on a railway locomotive due to the burnout of a resistance-capacitance resistor because of excessively high current. The traction loop resistance-capacitance protection resistor over-current detection device for the railway locomotive includes a power source module, a current signal acquisition module, a control module and a voice chip; the power source module converts a direct-current power source into voltage which is correspondingly required by the current signal acquisition module, the control module and the voice chip; and the control module compares the average value of the detection values of four current transformers with a set value and judges whether the current of the resistance-capacitance protection resistor is normal accordi
