Description

Technical Field

[0001] This utility model relates to the field of temperature sensor installation technology, and more specifically to a transformer-free temperature sensor installation structure. Background Technology

[0002] The climb-free transformer temperature sensor installation structure is an installation structure between a temperature sensor and a transformer. The transformer temperature sensor is a key device in the power system used to monitor the internal temperature of the transformer. Its main function is to monitor important parts of the transformer in real time, such as oil temperature, winding temperature, and core temperature, to ensure the safe operation of the transformer.

[0003] Existing transformerless temperature sensor installation structures require connecting the temperature controller and the sensor via a cable during daily use. However, the cable plug is prone to detaching when inserted into the sensor, which affects the user experience.

[0004] The existing non-climbing transformer temperature sensor installation structure requires the temperature controller to be bolted to the outside of the transformer during daily use, which requires the operator to use tools for installation, thus affecting the operator's user experience. Utility Model Content

[0013] Furthermore, the temperature controller has a bolt hole on its exterior, a cable bolt is movably fitted inside the bolt hole, and a cable connector is movably connected to the exterior of the cable bolt.

[0014] The technical effects and advantages of this utility model are as follows:

[0015] 1.
