Automatic inspector for voltage-regulating switch of electric locomotives



The utility model relates to an automatic inspector for a voltage-regulating switch of electric locomotives, comprising the computer part of an STDBUS bus functional module which adopts Z80ACPU as a core, a controlling switch panel, a photoelectric angle sensor, a TZ contacting resistance inspector and an A/D converter. The utility model can inspect the voltage-regulating switch when the voltage-regulating switch is in operation or to get down, the open-close angle of the main contact of the voltage-regulating switch, a contact resistance, the logic state of an auxiliary interlock, the action time of the voltage-regulating switch, the text of advance and retreat grade of the voltage-regulating switch, etc. can be inspected. The application of the utility model, which has the advantages of realization of automatic inspecting operation of the performance indexes of the voltage-regulating switch, high precision, high quality and safe operation, can effectively raise the examining and repairing quality of the voltage-regulating switch.
