Description
Technical field [0001] The invention belongs to the technical field of electronic switches, and in particular relates to an IGBT automatic power transmission device for overhead electric locomotives. Background technique [0002] The "Safety Regulations for Coal Mines" stipulate that the overhead line must be equipped with a section switch or automatic power supply switch at the place where personnel get on and off the vehicle, and the power supply of the overhead line must be cut off when the personnel get on and off the vehicle. [0003] The current automatic power-off and power transmission devices for DC overhead lines in underground yards generally use control technology based on analog amplifier circuits. The main circuit usually uses ZCO series DC contactors or thyristors as switching elements, but the DC contactors have simple functions and simple control. , The wiring is cumbersome, and the SCR requires a complicated shut-off circuit. In summary, the current DC overhead l...
