The invention relates to a switching station temperature monitoring device, and solves the problem existing that the structure of a switching station temperature monitoring device in the prior art is not reasonable, and technical personnel cannot maintain the switching station easily. With respect to the switching station temperature monitoring device, a server, a memory, a display, an environment temperature detector, an equipment temperature detector and a load temperature detector are arranged in a cabinet of the switching station, the environment temperature detector, the equipment temperature detector and the load temperature detector all communicate with the server, the load temperature detector comprises a first phase temperature detector, a second phase temperature detector and a third phase temperature detector, and the display communicates with the server. When maintaining the switching station, the technical personnel can determine the fault position conveniently in dependence on data displayed on the display, and the maintenance time of the switching station is greatly shortened; by arranging an air conditioner, electrical elements in the cabinet of the switching station work in a certain temperature scope, and the working environment of the electrical elements is optimized.
