Description

Technical Field

[0001] This utility model belongs to the field of busbar technology, specifically relating to an automatic temperature-measuring high-density busbar. Background Technology

[0002] Busbar trunking is a closed metal device composed of copper and aluminum busbar columns, used to distribute large amounts of power to various components in a distributed system. It has increasingly replaced wires and cables in indoor low-voltage power transmission trunk line projects. Adjacent busbar trunking sections are connected by copper sheets. High-density busbar trunking has strong heat dissipation capacity because the phases are tightly attached to each other and to the outer casing, thus withstanding greater electrical and thermal stresses. It can also quickly dissipate the heat generated by the conductive busbars. Its large current carrying capacity is also due to the tight attachment of the phases to each other and to the outer casing. In the prior art, utility model patent CN 221900530U discloses an automatic temperature-measuring high-density busbar trunking. It uses cams to adjust the spacing of the conductive copper busbars and can measure the temperature of the conductive copper busbars. However, the cam adjustment spacing is not precise enough, requiring the rotation of multiple cams for adjustment. Furthermore, the temperature sensor is located at the center of the cam, affecting real-time temperature monitoring. Utility Model Content

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0025] like Figure 1-5 As shown, the present invention discloses an automatic temperature-measuring high-density busbar trunking, including a bottom shell 1, a plurality of copper busbars 2 are arranged inside the bottom shell 1, and the copper busbars 2 are connected to an adjustment mechanism 3 that can change the spacing between adjacent copper busbars 2. The adjustment mechanism 3 includes a bracket 32 ​​for fixing the copper busbars 2, and a temperature sensor 42 is arranged on the bracket 32. The temperature sensor 42 is connected to a control module 4.

[0026] A cover plate 11 is fixed on the bottom shell 1, and a number of heat dissipation grooves 111 are provided on the cover plate 11 that communicate with the interior of the bottom shell 1.

[0027] The cover plate 11 is fixed to the top of the bottom shell 1 by bolts, and several heat dissipation grooves 111 are opened in the middle of the top surface of the cover plate 11 and are arranged at equal intervals.

[0028] The card holder 32 has a slot 321 for attaching the copper busbar 2. A slider 33 is fixed at the bottom of the card holder 32. The slider 33 is slidably connected in the groove on the bottom surface of the bottom shell 1.

[0029] The slot 321 has an upward opening to vertically engage the copper busbar 2. The copper busbar 2 is embedded in the slot 321 and fixed. The slider 33 is the base of the card holder 32. The bottom surface inside the bottom shell 1 has a groove. The slider 33 is restricted in the groove and can only make translational movements. At the same time, the groove is also designed to prevent the card holder 32 from making close contact with the adjacent copper busbar.

[0030] A threaded tube 322 is fixed to the side of the card holder 32. The threaded tube 322 is threadedly connected to the threaded section of the adjusting rod 31. The other end of the adjusting rod 31 extends out of the bottom shell 1 and is fixed with a knob 311. A limiting ring 312 is provided on the adjusting rod 31 to prevent the adjusting rod 31 from coming off the bottom shell 1.

[0031] The adjusting rod 31 passes through the through hole in the side wall of the bottom shell 1 and extends into the interior of the bottom shell 1. One end of the rod is threaded. Since the slider 33 is confined in the groove, the threaded section of the adjusting rod 31 will not come out of the threaded tube 322. The limiting ring 312 is a shaft section with a diameter larger than the through hole in the side wall of the bottom shell 1 and is rotatably connected to the side wall of the bottom shell 1.

[0032] Temperature sensor 42 is connected to telescopic tube 421. Data cable is installed inside telescopic tube 421, and the data cable connects temperature sensor 42 to control module 4.

[0033] The control module 4 is embedded in the outer wall of the bottom shell 1, and the telescopic tube 421 penetrates the bottom shell 1. One end is fixed to the bottom of the control module 4, and the telescopic section is connected to the temperature sensor 42.

[0034] The telescopic tube 421 is composed of two tubes of different diameters that are sleeved together. The two tubes are slidably connected, and the smaller diameter section is fixedly connected to the temperature sensor 42.

[0035] The two tubes can slide axially. The end of the telescopic section (smaller diameter) is provided with an annular protrusion to prevent it from coming out of the fixed section. The telescopic section is sleeved inside the fixed section (larger diameter) tube. Both tubes are hollow tubes with openings at the front and back.

[0036] The control module 4 is located on the outer wall of the bottom shell 1 and is equipped with a display screen 43 for displaying the detected temperature.

[0037] The display screen 43 is located on the front of the housing of the control module 4 and displays the temperature detected by the temperature sensor 42 in real time.

[0038] The control module 4 is connected to a temperature status indicator light 41, which is fixed to the outer wall of the bottom shell 1.

[0039] The control module integrates a PLC controller and circuit board. The power cord of the indicator light 41 is connected to the internal circuit board of the control module 4. Temperature parameters can be preset in the control module 4. When the temperature detected by the temperature sensor 42 exceeds the preset value, the control module 4 issues a control command, and the indicator light 41 turns red as an alarm. When the temperature does not exceed the preset value, the indicator light 41 is normally green.

[0040] The working principle of this utility model is as follows: (Refer to...) Figure 1-5 In this embodiment, three copper busbars 2 are provided inside the bottom shell 1. The middle copper busbar 2 is fixed. When it is necessary to adjust the spacing between adjacent copper busbars 2, the knob 311 is rotated to drive the adjusting rod 31 to rotate. Since the threaded section of the adjusting rod 31 and the threaded tube 322 on the side of the card holder 32 form a threaded engagement, when the adjusting rod 31 is rotated, the card holder 32 moves linearly in the groove on the bottom surface of the bottom shell 1 through the slider 33, thereby driving the copper busbars 2 fixed in the card slot 321 of the card holder 32 to move synchronously to achieve spacing adjustment. The temperature sensor 42 on the card holder 32 monitors the temperature of the copper busbar 2 in real time. The detection signal is transmitted to the control module 4 installed on the outer wall of the bottom shell 1 through the data line inside the telescopic tube 421. The control module 4 displays the temperature value on the display screen 43 and drives the indicator light 41 to switch the color state according to the preset temperature threshold. When the temperature is abnormal, the indicator light 41 emits a red warning and displays green under normal conditions. The heat dissipation slot 111 opened in the top cover plate 11 of the bottom shell 1 continuously exchanges internal air to assist the copper busbar 2 in heat dissipation.
