Wireless temperature measurement device

The invention relates to a wireless temperature measurement device, which solves the technical problem that the temperature at the junction part of a high-voltage bus and a switch inside a high-voltage switch cabinet cannot be accurately and effectively detected in the prior art. The wireless temperature measurement device comprises a wireless temperature sensor, a wireless temperature on-line monitoring instrument, a data converter and a computer. The wireless temperature sensor and the wireless temperature on-line monitoring instrument are connected via a multi-mode wireless device. The data converter and the wireless temperature on-line monitoring instrument are connected. The data converter and the computer are connected. The wireless temperature measurement device can be widely applied to the temperature detection field of high-voltage equipment in power plants and substations.
