Abstract
The utility model discloses a wireless temperature sensor of a switch cabinet, comprising a metal heat conducting plate and a circuit protection shell, wherein the metal heat conducting plate is arranged outside the circuit protection shell and is connected with the circuit protection shell. The wireless temperature sensor of the switch cabinet is characterized in that a temperature probe is arranged on one surface, in contact with an object to be measured, of the metal heat conducting plate. The loss of the metal heat conducting plate during the heat transferring process is reduced by shortening the distance between the temperature probe and the object to be measured, and both the temperature measurement accuracy and the response speed can be improved almost without increasing the cost, thereby timely and effectively measuring the temperature of a measured point and protecting power equipment.
