On the other hand, in power transmission and transforming equipment, two busbar connections place also exist a contact resistance, when an electric current passes through it, existence due to contact resistance, this place is caused to generate heat, if the temperature at this place exceedes setting, then can aggravate the oxidation of this contact point, the result of oxidation can cause that again contact resistance rises, caloric value is promoted to increase so again, temperature increases, ultimately cause equipment fault, therefore national standard, " GB/T11022-2011 " define to rated voltage 3.6kV and more than, the electric equipment of frequency 50Hz long-term work, such as chopper, isolation switch, gas insulated metal enclosed swit chgear, metal enclosed switchgear, the products such as on-load switch are for a long time by under rated operational current, electrically couple the numerical value that the temperature at position allows less than standard.

Owing to there is exposed high pressure in switchgear, space-closed is narrow and small, it is impossible to thermometric of manually patrolling, and has more point for measuring temperature, the problem such as cause temperature measuring equipment installation difficulty, adaptability poor. Traditional thermometric mode all cannot efficiently solve this problem. The development of digital temperature sensor so that complex environment on-line temperature monitoring is possibly realized. How by the multiple point for measuring temperature data in high-tension switch gear in real time, reliably, transmission easily be a crucial technical problem. ?he appearance of the radio network technique of ? Pseudo EEE802.15.4, the effectively transmission for device data provides a favourable instrument.
