[0032] The following is a further description of the embodiments of the present invention in conjunction with the accompanying drawings.

[0033] refer to Figure 1 , the embodiment of the present application provides a switch cabinet busbar temperature measuring device, comprising:

[0034] The housing 110 is provided with a first opening and a second opening;

[0035] The rotating shaft 120 is fixedly connected to the inside of the housing 110 through a positioning column;

[0036] A CT power coil steel belt 130, one side of the CT power coil steel belt 130 is connected to the temperature sensor assembly, the middle portion of the CT power coil steel belt 130 is wound around the rotating shaft 120, the first end 131 of the CT power coil steel belt extends out of the first opening, and the second end 132 of the CT power coil steel belt extends out of the second opening;

[0037] The metal connector 140 is fixedly connected to the first end 131 of the CT power taking coil steel belt, and the metal connector 140 is detachably connected to the second end 132 of the CT power taking coil steel belt.

[0038] It can be understood that the switch cabinet busbar temperature measuring device provided in the embodiment of the present application includes: a shell 110, the shell 110 is provided with a first opening and a second opening; a rotating shaft 120, the rotating shaft 120 is fixedly connected to the inside of the shell 110 through a positioning column; a CT power coil steel belt 130, one side of the CT power coil steel belt 130 is connected to the temperature sensing component, the middle part of the CT power coil steel belt 130 is wound on the rotating shaft 120, the first end 131 of the CT power coil steel belt extends out of the first opening, and the second end 132 of the CT power coil steel belt extends out of the second opening; a metal connector 140, the metal connector 140 is fixedly connected to the first end 131 of the CT power coil steel belt, and the metal connector 140 is detachably connected to the second end 132 of the CT power coil steel belt. Since the middle part of the CT power coil steel belt 130 is wound on the rotating shaft 120, the length of the CT power coil steel belt 130 extending out of the first opening or the second opening can be adjusted by pulling the first end 131 or the second end of the CT power coil steel belt to adapt to the switch cabinet busbar 200 of different sizes, refer to Figure 1 When the length of the CT power coil steel belt 130 extending out of the opening of the shell 110 is sufficient to encircle the target switch cabinet busbar 200 to be detected, the metal connector 140 fixedly connected to the first end 131 of the CT power coil steel belt is connected to the second end 132 of the CT power coil steel belt. At this time, the CT power coil steel belt 130 forms a closed loop, so that the temperature value of the switch cabinet busbar 200 can be measured; when the temperature measurement of the switch cabinet busbar 200 is completed, the second end 132 of the CT power coil steel belt is detached from the metal connector 140.

[0039] It should be noted that the embodiment of the present application does not limit the specific method of fixing the metal connector 140 to the first end 131 of the CT power coil steel belt. The metal connector 140 and the first end 131 of the CT power coil steel belt may be integrally formed, or the metal connector 140 may be welded to the first end 131 of the CT power coil steel belt. The technical personnel in this field may determine this based on actual conditions.

[0040] It should be noted that the embodiment of the present application does not limit the specific structure of the metal connector 140 and the specific manner in which the metal connector 140 is detachably connected to the second end 132 of the CT power taking coil steel belt. Figure 2In the case where the second end 132 of the CT power coil steel strip is provided with a bending portion 133, the metal connector 140 is provided with a third opening and a fourth opening, wherein the cross-sectional areas of the third opening and the fourth opening are greater than the cross-sectional area of ​​the bending portion 133 of the second end. When the second end 132 of the CT power coil steel strip passes through the fourth opening and the third opening in sequence, and the bending portion 133 is hooked on the edge of the third opening, the second end 132 of the CT power coil steel strip is connected to the metal connector 140. At this time, the CT power coil steel strip 130 forms a closed loop, so that the temperature value of the switch cabinet busbar 200 can be measured; when the temperature measurement of the switch cabinet busbar 200 is completed, the bending portion 133 of the second end 132 of the CT power coil steel strip is separated from the edge of the third opening, so that the metal connector 140 and the second end 132 of the CT power coil steel strip are disassembled from each other; the metal connector 140 can also be a snap connector, and the second end 132 of the CT power coil steel strip is provided with a connecting portion matching the snap connector, which can be determined by a technician in this field according to actual conditions.

[0041] It should be noted that the embodiment of the present application does not limit the specific length of the CT power coil steel belt 130, which can be 90 mm to 120 mm, and those skilled in the art can select it according to actual needs.

[0042] It should be noted that the embodiment of the present application does not limit the specific structure of the temperature sensor assembly, and may include a temperature sensor and a communication module, and the temperature sensor and the communication module are electrically connected. It is understandable that the temperature sensor assembly including the communication module can send the specific temperature value of the switch cabinet busbar 200 detected by the temperature sensor to the target object, such as the management server backend of the power switch cabinet, through the communication module, and can effectively monitor the specific parameters of the power switch cabinet.

[0043] In addition, the embodiments of the present application do not limit the specific structure of the communication module, which may be a WIFI module or a Bluetooth module as long as it can communicate with the target object and transmit data.

[0044] In addition, in some embodiments, the temperature sensing component may further include an alarm module, and the alarm module is electrically connected to the temperature sensor and the communication module respectively.

[0045] It is understandable that when the alarm module detects that the temperature value of the current temperature sensor exceeds the preset threshold, an alarm message is generated and sent to the target object through the communication module, so as to better maintain the safety of the switch cabinet busbar 200.

[0046] In some embodiments, an insulating tape is provided on one side of the CT power coil steel strip 130 away from the temperature sensing assembly.

[0047] It is understandable that the insulating tape provided on one side of the CT power coil steel belt 130 can protect the CT power coil steel belt 130, thereby effectively improving the service life of the switch cabinet busbar temperature measuring device.

[0048] In some embodiments, the switch cabinet busbar temperature measuring device further includes:

[0049] A force sensor, the force sensor is connected to a side of the CT power taking coil steel belt 130 away from the insulating tape;

[0050] A driving device, the driving device is electrically connected to the rotating shaft 120;

[0051] The control processing module is electrically connected to the driving device, the temperature sensing component and the force sensor respectively.

[0052] It can be understood that the switch cabinet busbar temperature measuring device of the embodiment of the present application also includes a force sensor, a drive device and a control processing module. The control processing module is electrically connected to the drive device, the temperature sensing assembly and the force sensor respectively. When the two ends of the CT power coil steel belt 130 are in contact with each other and are sleeved on the switch cabinet busbar 200, the control processing module can control the drive device to drive the rotating shaft 120 to rotate according to the force value sent by the force sensor, so as to automatically adjust the length of the CT power coil steel belt 130 to a size suitable for the switch cabinet busbar 200. For example, when the control processing module determines that the force value reaches a preset threshold, indicating that the CT power coil steel belt 130 is tightly wrapped around the switch cabinet busbar 200, the control drive device is stopped, so that the temperature value of the switch cabinet busbar 200 can be measured, thereby effectively improving the temperature detection efficiency of the switch cabinet busbar 200.

[0053] The above is a specific description of the preferred implementation of the present invention, but the present invention is not limited to the above implementation mode. Technical personnel familiar with the field can also make various equivalent deformations or substitutions without violating the spirit of the present invention. These equivalent deformations or substitutions are all included in the scope defined by the claims of the present invention.
