The implementation principle of the urban rail transit traction power supply comprehensive monitoring protection device in the embodiment of the application is as follows:
a first step of: when in use, one end of two lines to be connected is respectively connected with the two wiring components 9, a connecting line passes through a threading hole on the clamping frame during connection, and then a limiting screw is rotated to fix the connecting line, at the moment, the two lines are electrically connected through the two wiring components 9, the guide rod 8, the guide block 10 and the lead 3;
and a second step of: when the whole line is electrified, the iron column 2 is magnetized by the electrified lead 3, because the magnetic force on the iron column 2 is generated by current, the larger the current is, the larger the magnetic force on the iron column 2 is, at the moment, the larger the magnetic force on the iron column 2 is, when the current transmitted by the line is overloaded, the larger the magnetic force on the iron column 2 is, at the moment, the iron block 17 is influenced by the magnetic force on the iron column 2 and can approach the iron column 2, the iron block 17 can drive the slide cylinder 13 to move when moving, the slide cylinder 13 drives the feeler lever 15 to move while pressing the second spring 14, so that the feeler lever 15 is separated from the sensing head of the touch sensor 16, at the moment, the touch sensor 16 can feed back information to a control area, and when the current is unstable, the feeler lever 15 is repeatedly separated from the touch sensor 16, so that the control area can judge data according to different feedback of the touch sensor 16, and control the current in advance;
and a third step of: when the current transmitted by the circuit is overlarge, the iron block 17 is attached to the top end of the iron column 2 due to overlarge magnetic force of the iron column 2, when the iron block 17 is in contact with the iron column 2, the push rod 5 is extruded, the push rod 5 slides downwards while driving the supporting ring 7 to extrude the first spring 6, in the process, the guide rod 8 is driven to descend through the connecting rod, so that the guide rod 8 is separated from the guide block 10, at the moment, the circuit power-off protection work is realized, the iron column 2 loses magnetic force after the wire 3 is not electrified, then the sliding cylinder 13 drives the iron block 17 to ascend under the pushing of the second spring 14, meanwhile, the supporting ring 7 drives the push rod 5 to reset under the pushing of the first spring 6, and then the push rod 5 drives the guide rod 8 to contact with the guide block 10 again through the connecting rod, so that the circuit power-off is restored again after the power-off;
fourth step: meanwhile, when the iron block 17 moves, the L-shaped connecting frame 20 is driven to move by the telescopic rod 19, and the L-shaped connecting frame 20 drives the cleaning brush 21 to move, so that dust attached to the dust screen 23 can be automatically cleaned, and the influence of excessive dust on ventilation and heat dissipation inside the box body 1 is avoided.
