[0023] A detachable transformer temperature controller that is not powered off includes a probe 1, several wires 2, a meter 3, and an all-weather control system 4. The probe 1 has a retractable mounting bracket 5 on its top, which is also located on the top of the transformer. The two ends of the several sets of wires 2 are fixedly connected to quick-connect connectors 6. The wires 2, meter 3, and probe 1 use pluggable interfaces, allowing for individual replacement in case of failure without overall disassembly, thus increasing maintenance convenience. One side of the probe 1 is connected to the all-weather control system 4 via a wire 2 with a quick-connect connector 6, and the other side of the all-weather control system 4 is connected to the meter 3 via a wire 2 with a quick-connect connector 6. By using the retractable mounting bracket 5, the probe 1 can be disassembled and reassembled while energized, maintaining a safe distance. The all-weather control system 4 monitors the status of each module in real time, automatically alarms and initiates data backup in case of failure, ensuring continuous monitoring. This invention enables modular maintenance of the temperature controller, reduces the cost of replacing individual components, and supports live operation. Through intelligent monitoring and sealed design, the failure rate is reduced, significantly improving the safety of transformer operation.

[0024] In this embodiment, the telescopic mounting bracket 5 includes a support plate 501, a screw 502 threaded onto the support plate 501, a movable plate 503 rotatably connected to the bottom end of the screw 502 through the support plate 501, a probe 1 fixedly mounted on the bottom of the movable plate 503, and a rotating wheel 504 fixedly connected to the top end of the screw 502. By rotating the handwheel with an insulated tool, the screw 502 can be rotated, thereby causing the movable plate 503 to move along the axial direction of the screw 502. When the rotating wheel 504 is rotated in the forward or reverse direction, the probe 1 can be moved up and down.

[0025] Furthermore, a guide rod 7 is slidably inserted into the support plate 501. The bottom end of the guide rod 7 passes through the support plate 501 and is fixedly connected to the top of the movable plate 503. By setting the guide rod 7, the movable plate 503 is limited, making its movement process more stable.

[0026] It is worth mentioning that the bottom of the support plate 501 is fixedly connected with three sets of first hinge seats 8 in a circular array. The bottom of the three sets of first hinge seats 8 is respectively hinged with support rods 9. The bottom ends of the three sets of support rods 9 are respectively hinged with second hinge seats 10. The bottom of the three sets of second hinge seats 10 is respectively fixedly connected with mounting plates 11. The mounting plates 11 are fixedly installed on the top of the transformer. Through the cooperation of the first hinge seats 8, support rods 9 and second hinge seats 10, the support plate 501 is supported and positioned.

[0027] Specifically, the all-weather control system 4 includes a meter valve 401, one end of which is connected to the transformer temperature controller via a wire, and the other end of which is connected to a pneumatic valve 402. One end of the pneumatic valve 402 is connected to a connecting pipe 403, and the other end of the connecting pipe 403 is connected to an oil injection valve 406. It also includes a sensor valve 404, one end of which is connected to the oil injection valve 406, and the other end of which is connected to a sensor 405 via a wire. The all-weather control system 4 is also equipped with an exhaust valve 12, which is connected to the outside. By setting up the all-weather control system, the status of each module can be monitored in real time. In case of a fault, an alarm will be automatically triggered and data backup will be initiated to ensure continuous monitoring.

[0028] Furthermore, the quick-connect connector 6 includes a double-layer sealing ring 601, which is located at the interface of the wire 2. A pressure locking device 602 is provided on one side of the double-layer sealing ring 601. By using the double-layer sealing ring 601 and the pressure locking device 602 together, leakage of medium from the wire 2 can be prevented.
