Description

TECHNICAL FIELD

[0001] The utility model relates to wireless temperature measurement technical field, concretely relates to a contact temperature measurement sensor structure and high pressure cabinet inner contact part based on RFID technology. BACKGROUND

[0002] In view of the fault hidden danger of excessively high temperature rise caused by material aging, poor contact, current overload and other factors in electrical equipment contact point part, it is proposed that the temperature of these contact point parts needs to be monitored online. The wireless temperature measurement sensor in the prior art mostly uses built-in battery power supply to realize wireless monitoring, and part of them uses induction coil technology for induction power supply. The service life of the battery power supply is limited, which leads to limited product service life. And the use of induction coil power supply requires the installation of steel belt, and the efficiency of installation and removal of the steel belt is lower than that of the battery type.

[0003] At present, the power supply mode of the induction coil power supply type wireless temperature measurement sensor is to pass the steel belt through the coil inside the wireless temperature measurement sensor first, then bind the steel belt on the live cable through the clasp, induce the current on the cable through the closed loop steel belt, and then induce the current on the closed loop steel belt through the coil inside the wireless temperature measurement sensor to realize induction power supply. The method of binding the steel belt on the live cable through the clasp will make the steel belt bent during installation and need to be straightened during removal. For the test of the wireless temperature measurement sensor using induction coil power supply, the same steel belt must be used multiple times, and multiple bending will make the steel belt difficult to be straightened, greatly increasing the difficulty of installation and removal of the wireless temperature measurement sensor, thereby affecting the test efficiency of the wireless temperature measurement sensor. The built-in induction coil and steel belt installation of the induction coil power supply type require the overall volume to be limited and cannot be made smaller, and the installation method cannot change the multiple bending of the steel belt, which will reduce the power supply efficiency.
