[0035] In the present invention, the temperature of the copper bar is detected by the probe 2 passing through the connector 3 and contacting the copper bar. When the temperature is too high, an alarm is issued, which facilitates the maintenance, repair, and replacement of the connector 3, preventing adverse effects on the busbar and power system equipment. The moving component 5 can adjust the position of the probe 2 to correspond to the copper bar, being applicable to busbars of different specifications. The limiting component 7 maintains the state of the probe 2 in contact with the copper bar. When the temperature is too high, the limiting component 7 cancels the limitation on the probe 2, and the probe 2 folds and separates from the copper bar under the action of the connection structure 6, preventing high temperature from damaging the temperature measuring device.

[0036] Furthermore, in this embodiment, the connection structure 6 includes a connecting plate 61 fixedly arranged on the moving component 5. A connection groove 62 matching the connecting plate 61 is provided on the probe 2. The probe 2 is rotatably connected to the connecting plate 61, and the probe 2 can be rotated and folded, reducing the required space for convenient carrying. During installation, the probe 2 is rotated to contact the copper bar, and then the temperature of the copper bar can be measured.

[0037] In this embodiment, the probe 2 is rotatably connected to the connecting plate 61 through a rotating shaft, and a torsion spring 63 matching the probe 2 is arranged on the rotating shaft. A wire passing hole and a wire groove are provided on the connecting plate 61. By arranging the torsion spring 63, when the limiting component 7 releases the limitation on the probe 2, the probe 2 is rotated and folded by the force applied by the torsion spring 63, separating from the copper bar and contacting the main body 1, thereby avoiding burning out the probe 2 and the temperature measuring device due to high temperature. In some embodiments, a groove for accommodating the probe 2 is provided on the main body 1.

[0038] Even further, in this embodiment, the limiting component 7 includes a limiting plate 71. The limiting plate 71 abuts against the probe 2. A sliding groove is provided on the main body 1. The sliding groove is preferably a dovetail groove or a T-shaped groove. A sliding block 72 matching the sliding groove is arranged on the limiting plate 71. The sliding block 72 is preferably a corresponding dovetail block or T-shaped block. By arranging the sliding block 72 to cooperate with the limiting plate 71 to limit the position of the limiting plate 71, when the limiting plate 71 abuts against the probe 2, the probe 2 cannot be folded, thereby preventing the probe 2 from folding and separating from the copper bar during use, resulting in a temperature measurement failure.

[0039] In this embodiment, a tension spring 73 is arranged between the sliding groove and the sliding block 72. A thermal control structure 74 matching the limiting plate 71 is arranged on the main body 1. The limiting plate 71 is fixed by the thermal control structure 74 to prevent it from being pulled by the tension spring 73 and separating from the probe 2. When the temperature is too high, the thermal control structure 74 releases the restriction on the limiting plate 71, and the probe 2 folds and separates from the copper bar, playing a protective role. A gear 75 is rotatably arranged on the main body 1. Rack teeth meshing with the gear 75 are arranged on the limiting plates 71 in both detection areas. When one limiting plate 71 is fixed by the thermal control structure 74, the other limiting plate 71 is also fixed.

[0040] It should be noted that, in this embodiment, the thermal control structure 74 includes a bimetallic plate 741 arranged in the main body 1, and an insert block 742 is fixedly arranged on the bimetallic plate 741. A socket corresponding to the insert block 742 is opened on the limiting plate 71. When the temperature is too high, the bimetallic plate 741 is deformed, driving the insert block 742 to move and separate from the socket on the limiting plate 71, so that the limiting plate 71 and the slider 72 are pulled by the tension spring 73 to move along the slide groove and separate from the probe 2. The probe 2 is driven to fold by the torsion spring 63, thereby protecting the probe 2 and the temperature measuring device.

In this process, the positions of the connecting structure 6 and the probe 2 also change accordingly, so that it is suitable for bus ducts of different specifications.

[0042] In this embodiment, a winding chamber is provided in the movable block 51, and a wire reel 52 is rotatably arranged in the winding chamber. A wire connected to the probe 2 is wound on the wire reel 52, and a rotating shaft matched with the wire reel 52 is provided in the winding chamber. A winding spring 521 matched with the wire reel 52 is fixedly arranged on the rotating shaft. A through hole matched with the wire is provided on the movable block 51. The wire on the wire reel 52 passes through the threading hole of the connecting plate 61 along the through hole, and passes through the threading hole and is connected to the probe 2 along the wire groove. When the angle of the probe 2 changes, the wire extends or retracts accordingly, driving the wire reel 52 to rotate to reel in and release the wire, thereby preventing the wire from being too long and wrinkled to affect the normal use of the connecting structure 6.

The connecting part is electrically connected to the detection part 24 through the elastic conductive sheet 241, and the data detected by the detection part 24 is uploaded to the main body 1. The detection part 24 can be replaced to prevent inaccurate detection results due to aging after long-term use. The spring 23 applies force to the connecting rod 22, so that the connecting rod 22 and the detection part 24 are subjected to force, and the detection part 24 is tightly abutted against the copper busbar to prevent loosening, and it can be applicable to bus ducts of different specifications.

When the temperature is too high, an alarm is issued, and the alarm buzzes to warn;

[0048] When the temperature is too high, the bimetallic plate 741 is deformed, driving the plug 742 to move and separate from the socket on the limit plate 71, so that the limit plate 71 and the slider 72 are pulled by the tension spring 73 to move along the slide groove and separate from the probe 2. The probe 2 is driven by the torsion spring 63 to fold and separate from the copper bar, thereby avoiding high temperature burning of the probe 2 and the temperature measuring device;

[0049] After long-term use, the detection part 24 is disassembled, the connecting part is taken out, and the connecting part is inserted into a new detection part 24, and then the detection part 24 is threadedly connected to the connecting rod 22 to prevent the detection part 24 from aging after long-term use and causing inaccurate detection results.
