Abstract

An embodiment of the invention provides a voltage detection device and a power supply system of an electric locomotive. The voltage detection device is used for detecting voltage of a power grid and judging whether the voltage of the power grid fits a preset first threshold. When the voltage of the power grid fits the first threshold, an inverter is instructed to be operated normally. The voltage detection device is arranged at the top of the electric locomotive. The power supply system comprises the voltage detection device and the inverter, and the voltage detection device is used for detecting voltage of the power grid and judging whether the voltage of the power grid fits the preset first threshold. When the voltage of the power grid fits the first threshold, the inverter is instructed to be operated normally. The voltage detection device is arranged at the top of the electric locomotive. The inverter is used for supplying electricity to a traction motor of the locomotive under the condition that the voltage detection device sends out instructions.

Description

technical field [0001] The invention relates to the technical field of electric locomotives, in particular to a voltage detection device and a power supply system for electric locomotives. Background technique [0002] In an electric locomotive powered by electricity, an inverter is usually used to power the traction motor in the locomotive. The power required by the inverter comes from the power grid arranged on the train running line; and only when the grid voltage is maintained within a certain range, the inverter can work normally; when the grid voltage is too high or too low, it will Affects the inverter powering the traction motors in the locomotive. Therefore, the inverter often needs to cooperate with a voltage detection device capable of detecting the grid voltage to realize its function. [0003] At present, the voltage detection device for the inverter to detect the grid voltage is generally integrated in the inverter. In other words, in the train power supply ...
