Description

technical field [0001] The invention relates to a pantograph-catenary pressure detection device, belonging to the technical field of rail transit. Background technique [0002] In all kinds of rail vehicles, the operation stability and reliability of the pantograph-catenary mechanism are the necessary basic conditions to ensure the safe and reliable operation of rail vehicles. During the operation of the equipment, due to terrain changes, airflow changes, and equipment aging Affected by many factors, such as pantograph-catenary equipment of electric locomotives, the pressure on the contact surface between the pantograph and the power supply network fluctuates greatly during operation. When the pressure on the contact surface is insufficient, it is very easy to cause False connection, while affecting the stability of the vehicle's electric energy acquisition, can also easily lead to arcing between the pantograph and the power supply network, which seriously affects the servic...

[0002] In all kinds of rail vehicles, the operation stability and reliability of the pantograph-catenary mechanism are the necessary basic conditions to ensure the safe and reliable operation of rail vehicles. During the operation of the equipment, due to terrain changes, airflow changes, and equipment aging Affected by many factors, such as pantograph-catenary equipment of electric locomotives, the pressure on the contact surface between the pantograph and the power supply network fluctuates greatly during operation. When the pressure on the contact surface is insufficient, it is very easy to cause False connection, while affecting the stability of the vehicle's electric energy acquisition, can also easily lead to arcing between the pantograph and the power supply network, which seriously affects the service life of the equipment and the safety of the vehicle. When the contact surface pressure is too large, it will cause The friction loss between the pantograph and the power supply network increases, and it is easy to cause the local bending phenomenon of the receiving network due to the excessive pantograph lift. While increasing the friction loss to the receiving network, it is easy to cause the fatigue damage of the power supply network to increase. , has seriously affected the stability and reliability of the power supply network and pantograph equipment operation, and led to an increase in the failure rate of equipment operation. Therefore, in view of this situation, it is urgent to develop a new pantograph-catenary mechanism operation pressure detection device to meet Pantograph-catenary mechanism operating needs
