The transformer substation switch box operation mobile robot comprises a robot body, a mobile platform, a mechanical arm, a two-dimension code scanner, a power supply management system, a motion control system and a visual sensing system, wherein the mobile platform is arranged at the lower part of the robot body, and is a crawler-type mobile platform; the power supply management system and the motion control system are arranged in the robot body; the mechanical arm is mounted above the robot body; the visual sensing system is mounted above the tail end of the mechanical arm; and the two-dimension code scanner is arranged under the robot body. The transformer substation switch box operation mobile robot has the characteristics of high precision, stability in operation, safety, reliability, etc., can realize the effect of artificial intelligence operation, and can replace humans to realize the effect of standard operation.

A cooking platform includes a first oven having a first electric cooking element, and a second oven includes a second electric cooking element. A power management system is used to distribute power such that when the second electric cooking element is energized the first electric cooking element is de-energized.

The invention discloses a topological structure of a power electronic transformer, and relates to the technical field of transformers. The topological structure comprises voltage input equipment, a power electronic transformer, a power management system, a pre-start detection unit, a control unit, a fault detection unit, a fault analysis unit and a fault feedback unit. Before the power electronic transformer is started to work, the transformer can be subjected to pilot operation before working through the pre-starting detection unit, and operation data is called from data through the previous operation data calling module, so that whether the transformer can work normally or not can be found in time, and then the situation that the power transformer needs to stop working for maintenance when the power transformer breaks down during working is avoided; the fault detection unit can extract the real-time working data of the transformer through the information extraction module, retrieves the data of the transformer during normal operation through the original data retrieval module, compares the data through the data comparison module, and then can detect the existing working condition of the transformer.
