[0002] In the power system, high-voltage switchgear is widely used in power generation, transmission, distribution, and power conversion. As the currently commonly used trolley switchgear, the circuit breaker and the switchgear are connected by plugs. When the trolley and the switchgear are poorly manufactured, transported, or installed, the contacts will fail.

[0003] If a short circuit or poor contact occurs, the contact resistance will increase, resulting in excessive contact temperature. When the maintenance personnel are analyzing and repairing the fault, they may easily touch the contact and get burned. At the same time, since the contact is located inside the cabinet, the fault caused by poor contact is not easy to be found by the maintenance personnel.

[0004] Therefore, in view of the above problems, the utility model provides a substation switch cabinet trolley contact temperature measuring device to meet the needs. Utility Model Content

[0007] In order to facilitate the routing of the temperature sensor in the rubber sleeve, as a preferred embodiment of the utility model for measuring the contact temperature of a substation switch cabinet trolley, the sensor sleeve, the wiring sleeve and the temperature display sleeve are all connected.

[0008] As a preferred embodiment of the temperature measuring device for contacts of a substation switch cabinet trolley of the utility model, the sensor probe and the temperature display are electrically connected via a connecting line.
