摘要（英）：

The invention discloses a method for combined detection of the current and the temperature of an electrified through-current part of electric equipment. The method comprises the following steps of: measuring 50%-120% of current data of the electrified through-current part in the rated through-current range by adopting a coil device with the measuring accuracy being 5%; and measuring single-point temperature data of the metal surface of the electrified through-current part by adopting a thermoelectric couple. A detecting device is arranged on the electrified through-current part; power is supplied synchronously by induction coils for measuring the current data of the electrified through-current part, a wireless mode is adopted for transmitting measured data of the current and the temperature so as to carry out communication with a remote receiving device arranged in an equipment grounding shell or on the ground. The method disclosed by the invention has the obvious advantages that the installation is convenient, the negative influence on operation is less, the parameter detection is comprehensive, and no influence is caused to the existing measuring and controlling device and the like.
