1. A temperature monitoring system for an electric power-applied section, comprising:

  • a temperature history recording means for measuring a temperature of said electric power-applied section and recording said temperature as a temperature history together with its measurement time; and

    a control means for controlling the recording and a transmitting operation of said temperature history at a first predetermined interval,wherein said temperature history recording means comprises;

    a temperature sensor that generates a temperature detection signal according to said temperature;

    a memory that stores, as said temperature history, a measured temperature and a measurement time based on said temperature detection signal; and

    a housing comprising a watertight circuit housing portion being formed to make a thermometric surface of said temperature sensor contact a measured object, wherein said memory comprises;

    a history memory that stores, in a time series, said temperature history; and

    a temperature alarm memory that stores, in a time series, as a temperature alarm, a temperature history being out of a range of a normal temperature, andwherein;

    said control means controls said temperature history recording means to conduct a recording operation of the temperature history at a second predetermined time interval that is shorter than said first predetermined time interval when a temperature history is stored in said temperature alarm memory.
