Title:
ELECTRIC LOCOMOTIVE MAIN CIRCUIT AND ELECTRIC LOCOMOTIVE
Document Type and Number:
WIPO Patent Application WO/2018/107384
Kind Code:
A1
Abstract:
An electric locomotive main circuit and an electric locomotive. The electric locomotive main circuit comprises an alternating current power network locomotive main circuit, a direct current power network locomotive main circuit, an alternating current-direct current power network voltage detecting device, a first change-over switch, and a control device; the alternating current-direct current power network voltage detecting device is connected to an output end of a high-voltage isolating switch to detect the current power network voltage of the circuit and send same to the control device; the control device is separately connected to the alternating current-direct current power network voltage detecting device and a control end of the first change-over switch, determines the current network touch state according to the current power network voltage, and controls the on-off state of the first change-over switch; a first end of the first change-over switch is connected to a grounding end, and a second end of the first change-over switch is connected to an input end of the direct current power network locomotive main circuit. The circuit can control the on-off state of the first change-over switch according to the current network touch state and automatically converts the running mode, so that the electric locomotive runs under the alternating current-direct current overhead line system compatibly.
