Connection terminal overtemperature early-warning system

The utility model relates to the technical field of connection terminal overtemperature early-warning, and specifically relates to a connection terminal overtemperature early-warning system. The utility model solves the problems that the conventional connection terminal overtemperature early-warning technology has the disadvantages of manpower waste and complex operation, and is prone to break the original wiring of a power distribution cabinet, increase the difficulty in the wiring of the power distribution cabinet, and increase the normal maintenance points and the workload of maintenance of the power distribution cabinet. The system comprises a chemical temperature change head, a gas sensitive detector, a data processing module, a monitoring PC, a sound-light alarm, a wireless transmission module and a mobile phone. An output terminal of the chemical temperature change head is connected with an input terminal of the gas sensitive detector. An output terminal of the gas sensitive detector is connected with
