Description

Technical Field

[0001] This utility model relates to the field of busbar trunking technology, and in particular to a busbar trunking connector temperature measuring box that is easy to fix and its application in busbar trunking. Background Technology

[0002] When a busbar trunking system is under overload, increased contact resistance at the joints can lead to overheating, accelerated insulation aging, and even breakdown, causing short circuits. During capacity expansion, over 90% of faults originate at the joints, primarily due to excessive contact resistance and high temperatures. Therefore, real-time monitoring of connector temperatures is crucial for fault prevention and ensuring power system safety. The existing temperature sensing box shell is a pre-packaged, enclosed plastic box. Additional holes need to be drilled in the plastic box to install a protective coil, facilitating the insertion of network cables through punched holes into the module's network port. Furthermore, to secure the plastic box to the top of the busbar trunking, an additional sheet metal piece needs to be fabricated and fixed to the bottom of the plastic box before being attached to the top of the busbar trunking. The entire manufacturing and assembly process is not only complex but also relatively costly. Utility Model Content

[0003] To address the aforementioned problems, this utility model discloses a busbar trunking connector temperature measuring box that is easy to fix and its application in the busbar trunking. The connector box is made of sheet metal bending, which facilitates assembly and fixation, simplifies the manufacturing process, and reduces manufacturing costs.

[0004] The specific technical solution is as follows:

[0005] A temperature measuring box for easy fixing of a busbar connector includes a temperature measuring box body. The temperature measuring box body includes a cover plate and a bottom plate. The cover plate includes a top plate, side plates, and a mounting plate. The side plates are longitudinally connected to both sides of the top plate. One side plate has an opening for embedding and installing the front protrusion of the temperature measuring module. The lower end of the other side plate extends horizontally outward to form the mounting plate. The bottom plate is disposed at the bottom end of the cover plate. The two sides of the bottom plate are bent upward to form folded plates. The two folded plates are respectively attached to the two side plates and connected and fixed by fasteners. The bottom plate has a notch on the side away from the opening. One end of the notch extends vertically upward to form a groove plate. The upper end of the groove plate is narrowed on both sides to form support grooves, so that the upper end of the groove plate is longitudinally embedded into the rear groove of the temperature measuring module and the rear end of the temperature measuring module is supported by the support grooves, thereby realizing the installation and positioning of the temperature measuring module by the temperature measuring box body.

[0006] Furthermore, the temperature measuring box body has openings at both ends.

[0007] Furthermore, both the cover plate and the bottom plate are formed by bending sheet metal.

[0008] Furthermore, the mounting plate has mounting holes at both ends for mounting on the busbar trough.

[0009] Furthermore, corresponding screw holes are provided at both ends of the lower side of the side plate and at both ends of the folding plate, so that the side plate and the folding plate are fixed together by fasteners passing through the screw holes.

[0010] Furthermore, the bottom end of the support groove and the bottom end of the opening are at the same horizontal position.

[0011] Furthermore, the top of the groove plate is positioned close to the top plate.

[0012] Furthermore, the housing shape of the temperature measuring module is the same as that of the miniature circuit breaker.

[0013] Another objective of this utility model is to provide a busbar trunking, including a busbar trunking body and an inter-segment connector disposed between the busbar trunking bodies. The inter-segment connector is fitted with a protective plate fixed to the busbar trunking body on its outer side, and a temperature measuring box is installed on the top of the protective plate. The temperature measuring box is the aforementioned temperature measuring box.

[0014] The beneficial effects of this utility model are reflected in:

[0015] (1) Compared with the traditional use of finished plastic boxes, the temperature measuring box in this utility model is assembled by splicing sheet metal forming of the cover plate and the bottom plate, which eliminates the need to make additional sheet metal mounting parts for fixing, effectively reducing the manufacturing cost and shortening the production cycle.

[0016] (2) In this utility model, the bottom plate and the cover plate are spliced ​​together and fixed by fasteners, which makes installation convenient. The temperature measuring box is installed and positioned at both ends of the micro-section temperature measuring module through the through-hole and the slot plate, respectively, without the need for additional holes.
