Fault loading device for diesel locomotive

Abstract

The invention discloses an internal combustion locomotive fault loading device. The internal combustion locomotive fault loading device comprises an input circuit, a photoelectric coupler, a power supply voltage, a microprocessor, a locomotive internal power supply, a fault switch and an output circuit, wherein the input circuit is in circuit connection with the photoelectric coupler; the power supply voltage is grounded and connected with the microprocessor through the photoelectric coupler; the rear portion of the microprocessor is grounded and connected with the locomotive internal power supply through a triode; the rear portion of the locomotive internal power supply is connected with the output circuit through a relay and the fault switch. According to the internal combustion locomotive fault loading device, the microprocessor is used as the core, normal operation logic of an LC electric appliance and an LLC electric appliance is controlled according to instructions of a driver controller, and low-current breaking of the LC electric appliance is guaranteed; the loading requirements of the driver controller when a contact finger of the driver controller breaks down are met; the fault loading device is used for controlling the corresponding electric appliances to act in a reasonable mode, so the reliability of operation of a DF4 locomotive is effectively improved, and the locomotive failure rate is lowered.

Description

technical field [0001] The invention relates to a fault loading device for a diesel locomotive, belonging to the technical field of diesel locomotives. Background technique [0002] At present, my country is still using a large number of DF4 diesel locomotives as railway traction power locomotives. [0003] During the use of domestic DF4 diesel locomotives, the LC, LLC and other electrical appliances often fail to operate normally due to the failure of the loading circuit electrical appliances, resulting in no pressure and no flow of the locomotive, and the traction operation cannot continue, resulting in machine breakage. Some domestic locomotive depots use external switches to supply power to LC and LLC electrical appliances, so that the locomotive can continue to traction. When the locomotive is unloaded, the LC and LLC electrical appliances lose power at the same time, causing severe arcing of the LC electrical appliances and easy to burn out; and the machine control sw...
