Description

technical field [0001] The invention belongs to the technical field of electric traction rail transit, and in particular relates to a detection device for electric traction. Background technique [0002] When electric traction rail vehicles, taking power from the catenary and converting it into mechanical energy for driving is a necessary condition for the normal operation of rail vehicles. In the actual operation of the train, the traction system must be friendly to the power grid, namely: low interference current, high power factor, 4QS operation, etc. [0003] In the design and manufacture process of high-power high-voltage and low-voltage electric traction devices, due to the irregularity of the catenary or the vibration of the pantograph, the pantograph's jumping bow condition in the actual operation process and the special transition process of the network voltage sudden drop during operation , usually there will be instantaneous overvoltage and overcurrent of the con...
