Contact type temperature sensor for high and medium voltage switch cabinet

The invention discloses a middle-high voltage switch tank contacting temperature sensor. A thermistor probe is installed on the surface of an insulated heat conducting base; the thermistor probe with epoxy resin covered around is fixed with the insulated heat conducting base, wherein the epoxy resin has a metal shielding shell covered on it, the lead wires of the thermistor probe go through the hole on the metal shielding shell, the insulated heat conducting base is equipped with an installation hole. The Pt resistor packed with epoxy resin can sense temperature entirely and uniformly. The base made from nanometer material AIN has good heat conductivity and reliable electricity insulation. The probe shielded with iron shell can shield electromagnetic disturbance in the middle-high voltage switch tank. The invention can be applied in the middle-high voltage electronic switch tank working between 10kv and 35kv.
