Background
In the prior art, the temperature measuring pad strip is of an integrated structure. The temperature measuring pad strip for the generator stator is formed by packaging a bottom plate, a platinum thermal resistor and a cover plate, is glued or encapsulated by insulating glue and epoxy putty, and cannot be detached. Particularly, the platinum thermal resistor and the bottom plate are fixedly bonded together, and when the platinum thermal resistor fails, the rotor and the wire pulling rod must be hung for replacement, so that the disassembly and the replacement are very difficult. The part of the power station where the temperature measuring filler strip is installed is generally provided with a generator stator winding and a stator iron core. The temperature measuring pad strip of the power station is not influenced by the running state of the generator set and runs uninterruptedly after being put into operation, and the running time is very long. During the manufacturing process of the motor, a stator temperature measuring pad strip is placed between a stator coil and a stator core in advance and used for measuring the average temperature of the stator core. After the stator temperature measurement filler strip breaks down, the stator coil can only be removed for replacement after the stator coil is overhauled. Therefore, the problems of long period and high cost for replacing the temperature measuring pad strip are solved.
