An automatic medium-voltage dual-power-supply switching device, comprising an input module (11), an acquisition module (12), a control and communication module (14), an output module (13) and a power supply module (15), wherein the acquisition module comprises a plurality of voltage input channels (21) and a plurality of current input channels (22); the input module is used for receiving a first switch amount signal; the acquisition module is used for acquiring information, the information including a voltage, frequency and current; the output module is used for outputting a second switch amount signal; the communication module is used for communicating with a peripheral equipment; and the power supply module is used for supplying power to the input module, the acquisition module, the communication module and the output module. The switching device can not only measure a voltage signal, but can also measure a current signal and also has extensible voltage input channels and current input channels at the same time, and a touch screen can also display the acquired information in a graphic manner, which is intuitive and clear. |
