[0002] As a key equipment in the power system, the operation safety and reliability of the generator directly affect the stable operation of the entire generator set.

[0003] In a large thermal power generator set, the temperature rise of the generator stator coil and the core is an important indicator reflecting the operation state of the equipment. In order to monitor the temperature of the stator coil in real time, temperature measurement elements are usually installed on the inner wall or end of the generator stator winding, and are connected to the measurement circuit through the temperature measurement socket, so as to realize wall temperature detection.

[0004] On the other hand, in order to ensure the safety of the generator insulation system, the stator winding needs to be subjected to a withstand voltage test during equipment manufacturing or maintenance to verify whether the insulation strength meets the requirements. During the withstand voltage test, the original temperature measurement circuit must be disconnected and replaced with a withstand voltage test circuit to prevent damage to the measurement system caused by high voltage.

[0005] In the prior art, the wall temperature measurement and withstand voltage test of the generator are generally realized through two independent plug-in structures, i.e., the temperature measurement plug and the withstand voltage plug are connected to the corresponding test systems, respectively.
