Technical Field
The invention relates to a pantograph technology, in particular to a multifunctional high-speed pantograph auxiliary pantograph lifting device.
Background
The pantograph plays the effect of two-way transmission pivot between contact net and train: the electric energy is obtained from the contact network to supply power to the whole train electric system, and meanwhile, the kinetic energy of the train is converted into the electric energy to be fed back to the contact network through the regenerative braking system of the train to be supplied to other on-line trains.
In the process of operating and overhauling the pantograph of the high-speed motor train unit, the fault that the pantograph cannot normally rise and receive current due to the reasons of low initial pantograph-lifting force, adhesion of a supporting buffer rubber pile and a pantograph body, freezing of ice and snow and the like often occurs.
In the high-speed running process of the pantograph of the high-speed motor train unit, the problem that the standby folding pantograph floats to contact with the network cable due to the impact influence of tunnel effect airflow waves when the standby folding pantograph enters and exits the tunnel at a high speed easily occurs because of high running speed, so that the network cable voltage is led to a train end through the standby folding pantograph. Under extreme conditions, when the two bows are respectively in contact with the contact networks of the two phase separation areas, if the motor train unit does not adopt effective isolation measures for the standby folding pantograph, the contact networks are short-circuited, and serious adverse effects influencing transportation safety are caused.
