The present invention discloses a temperature measurement and automatic control cooling apparatus of joint wires of electrical equipment. The temperature measurement and automatic control cooling apparatus comprises a conductor clip connected with the joint of the electrical equipment, wherein the conductor clip is characterized in that a temperature measurement arc dual-metal sheet is arranged at the upper end of the conductor clip; the upper end of the temperature measurement arc dual-metal sheet is connected with an over-temperature control apparatus through connecting with an amplification connecting rod and a conductor wafer on the upper end of the amplification connecting rod; a cooling device is launched when the temperature is within the range of 30 DEG C to 50 DEG C; and maintainers receive notifications through a mobile phone when the temperature is within the range of 40 DEG C to 45 DEG C. According to the temperature measurement and automatic control cooling apparatus of joint wires of the electrical equipment provided by the invention, the on-line temperature measurement of the joint of the electrical equipment may be realized, and automatic cooling or information transmission may be achieved according to the warming limit value of the joint of the electrical equipment, thereby realizing on-line automatic cooling process, prolonging the service life of the joint of the electrical equipment, reducing the times of maintenance, avoiding the influence of the hot weather, and decreasing the oxidation and scaling contact surface because of the winding of a water outlet fine rubber tube.
