Pantograph control device and railway vehicle

Abstract

The invention provides a pantograph control device and a railway vehicle. The pantograph control device comprises two pantograph control circuits which are respectively used for controlling the pantograph descending on the two sides, wherein each of the pantograph control circuits comprises a control switch, a primary relay and an opposite-side primary relay switch which are serially arranged; when the control switch or the opposite-side primary relay switch is switched off, the primary relay is powered off; the control switch is switched on or off under the operation of a user; the primary relay is used for controlling the pantograph descending under a powered off state; the opposite-side primary relay switch is controlled by an opposite-side primary relay and is switched off when the opposite-side primary relay is powered off. The pantograph control device and the railway vehicle provided by the invention have the advantages that the structure is simple, the complex network device is not required, the transmission efficiency and the safety are promoted, the simultaneous descending of the pantographs on the two sides can be realized and the service life of the pantographs can be prolonged.

Description

technical field

[0001] The invention relates to rail transit technology, in particular to a pantograph control device and a rail vehicle. Background technique

[0002] The pantograph is an electrical device in a rail vehicle that obtains electrical energy from the catenary. It is generally installed on the roof and plays an important role in the normal operation of the vehicle.

[0003] When an emergency occurs during the operation of the vehicle, such as the pantograph cannot be lowered normally, and the main circuit breaker cannot be opened normally, it is necessary to lower the pantograph through the pantograph shutdown control circuit.

[0004] At present, the pantograph shut-off control circuit mostly relies on the network to control the pantograph. The transmission path of the circuit control signal is long and passes through many devices. The pantograph function cannot be executed or mis-executed, resulting in low transmission efficiency of the control circuit and hi...
