[0002] Transformer monitor is an instrument used to monitor the operating status of transformers. It can monitor the temperature, voltage, current, power and other parameters of transformers in real time, and transmit these data to the monitoring center or other equipment, so as to detect abnormal conditions of transformers in time and ensure the safe operation of transformers.
[0003] Traditional transformer detectors are not portable due to their large size. When testing transformers, multiple transformers often need to be tested. The large size of the equipment prevents it from being moved quickly, which prolongs the working time. At the same time, since multiple circuit lines need to be connected at the same time during transformer testing, entanglement may occur between the circuit lines. Utility Model Content

[0023] In a preferred embodiment, the two ends of the clockwork spring 6 are overlapped with the inner wall of the winding column 5 and the outer wall of the fixed column 4 respectively, and the outermost circle of the clockwork spring 6 is in contact with the inner wall of the winding column 5. In the above structure, by pulling the detection wire 7, the winding column 5 is driven to rotate on the outer wall of the fixed column 4, so that the clockwork spring 6 expands. When the pulling force of the detection wire 7 disappears, the clockwork spring 6 retracts, driving the winding column 5 to rotate on the outer wall of the fixed column 4, so that the winding column 5 is reset to rewind the detection wire 7.
[0024] In a preferred embodiment, the wire passing slot 8 is L-shaped, passing through the box body 1, and the detection wire 7 passes through the wire passing slot 8 to reach the top of the box body 1, and the bottom diameter of the connecting plug 11 is larger than the diameter of the wire passing slot 8. In the above structure, by pulling the connecting probe 10, the connecting probe 10 drives the detection wire 7 to slide on the inner wall of the wire passing slot 8, so that the end of the detection wire 7 close to the connecting probe 10 can be pulled, and when the detection wire 7 is rolled up, the connecting probe 10 touches the top of the box body 1, so that the detection wire 7 is fixed.
[0025] In a preferred embodiment, a square piece is provided on the top of the inner wall of the box body 1, and a circular groove is provided above the square piece, and the diameter of the circular groove is smaller than the diameter of the bottom of the detection probe 9.

When the detection probe 9 touches the square piece on the inner wall of the box body 1, the detection probe 9 fixes the detection wire 7.

When the contraction spring 16 is separated from the fixed semicircular ring 12, the box cover 2 is rotated to make the box cover 2 leave the top surface of the box body 1, and the connection probe 10 is pulled. The connection probe 10 drives the detection wire 7 to slide inside the wire through groove 8, and the connection probe 10 is inserted into the connection plug 11. The detection probe 9 is pulled, and the detection probe 9 drives the other end of the detection wire 7, so that the detection wire 7 is out of the box body 1. The winding column 5 is driven to rotate on the outer wall of the fixed column 4. When the winding column 5 rotates, the outer ring of the clockwork spring 6 is driven to rotate, so that the clockwork spring 6 expands, and the detection probe 9 is inserted into the detection port to measure the transformer. When the measurement is completed, the detection probe 9 is pulled out to separate the detection probe 9 from the detection port. At this time, the clockwork spring 6 retracts, driving the winding column 5 to rotate, so that the winding column 5 rewinds the detection wire 7, pulls the connecting probe 10 out of the connecting plug 11, resets the box body 1 and the box cover 2, and completes the work.
