Specific embodiment:
[0031] The pantograph control device uses the bowhead airbag 6 and the pressure sensor 5 to detect the contact force between the pantograph and the catenary, and adopts closed-loop control to adjust the pantograph-net contact force. The control device has the advantages of small adjustment error of the pantograph and net contact force and strong interference suppression ability, thereby reducing energy consumption, prolonging the service life of the pantograph and net, improving the current receiving performance, and ensuring the safe and reliable operation of the train.
[0032] Such as figure 1 , figure 2 As shown, the pantograph control device includes an air cleaner 1, an electronically controlled pressure regulating valve 2, a silencer 3, a reversing solenoid valve 4, a bow raising throttle valve 7, a bow lowering throttle valve 8, and a safety valve 9. 1. The bow raising airbag 10 further includes: a pressure sensor 5, a bowhead airbag 6 and a control...
