Problems solved by technology
[0002] Existing rolling stock introduces high-voltage alternating current or high-voltage direct current from the high-voltage grid line through the vehicle pantograph as the power supply energy. The high-voltage alternating current or high-voltage direct current is supplied to each power consumption unit after passing through the transformer equipment. Equipment burnt down, vehicles out of service
At the same time, the stability and continuity of vehicle operation is very important for operation management. The voltage monitoring system needs to be stable and reliable to minimize false protection and leakage protection. At present, there is no relevant locomotive voltage and current monitoring system.

Embodiment Construction
[0035] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.
[0036] like figure 1 As shown, the locomotive power supply electrical protection device in this embodiment includes an analog input module 1, a control module 2 and a digital output module 3;
[0037] The analog input module 1 is connected to the control module 2 and the digital output module 3 respectively, and is used to obtain the power supply parameters of the locomotive, including voltage, current, etc., and process the parameters before sending them to the control module 2; at the same time, the processed The parameter is compared with the preset value, and when the parameter exceeds the preset value, a protection command is sent to the digital output module 3;
[0038] The control module 2 is used to output the protection instruction to the digital output module 3 when the analog input module 1 sends the protection instruction to the digi...

The invention discloses a locomotive power supply electrical protection device and a control method, comprising an analog input module for acquiring locomotive power supply parameters, processing the parameters and then sending them to a control module; Compare, and send a protection command to the digital output module when the parameter exceeds the preset value; the control module is used to output the protection command to the digital output module when the analog input module sends the protection command to the digital output module; At the same time, the received processed parameters are compared with the predetermined value, and when the parameter exceeds the predetermined value, a protection command is sent to the digital output module; the digital output module is used to receive protection commands from the analog input module and the control module. , the external output protection operation command. The device and method of the present invention have the advantages of simple structure, stable and reliable communication, and reliable operation of the locomotive.
Description
technical field [0001] The invention mainly relates to the technical field of locomotive power supply monitoring, in particular to a locomotive power supply electrical protection device and a control method. Background technique [0002] The existing locomotives and rolling stock introduce high-voltage alternating current or high-voltage direct current from the high-voltage grid line through the vehicle pantograph as the power supply energy. Equipment burned and vehicles out of service. At the same time, the stability and continuity of vehicle operation are very important for operation management. The voltage monitoring system needs to be stable and reliable to minimize false protection and leakage protection. At present, there is no relevant locomotive voltage and current monitoring system. SUMMARY OF THE INVENTION [0003] The technical problem to be solved by the present invention is as follows: in view of the technical problems existing in the prior art, the present i...
