[0002] A busbar is a power conductor, usually a high-current conductive line made of materials such as copper or aluminum. Generally, busbars have a large cross-sectional area and can therefore withstand a large current load. A bus duct is a fixed or movable device used to accommodate and protect busbars in electrical equipment.
[0003] In the related technologies, bus ducts are mostly used in the core working areas of important data centers, and most of the power supply objects are loads with extremely high safety requirements. Therefore, monitoring the temperature rise changes of the busbar during use has a relatively important risk warning significance.

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0026] In the related technologies, bus ducts are mostly used in the core working areas of important data centers, and most of the power supply objects are loads with extremely high safety requirements. Therefore, monitoring the temperature rise changes of the busbar during use has a relatively important risk warning significance.
[0027] like Figure 1-Figure 2 As shown, the temperature-controlled bus duct provided in the embodiment of the present application includes a bus duct body 100, a color-changing temperature measuring patch 600 and a temperature sensor 700, wherein the bus duct body 100 is composed of a first side panel 200, a second side panel 300 and a top panel 400, and the first side panel 200, the second side panel 300 and the top panel 400 form a metal structure with a U-shaped cross-section. In addition, the first side panel 200, the second side panel 300 and the top panel 400 form a slot 500 structure, and the slot 500 can be used to place and install multiple busbars. In addition, the input end of the bus duct body 100 is electrically connected to the starting box, and the output end of the bus duct body 100 is electrically connected to the plug-in box.
[0028] Of course, the bus duct body 100 also includes a variety of structures well known to those skilled in the art, which will not be described in detail in this embodiment. In addition, the first side plate 200, the second side plate 300 and the top plate 400 of the bus duct body 100 are all integrally formed, and this embodiment is described separately here only for ease of understanding.
[0029] The color-changing temperature measuring patch 600 is also called a temperature-indicating recording label, which has a temperature-sensitive chip inside and a sensor lamp 800 connected to the chip installed outside. After the chip senses a change in temperature, it can control the color of the sensor lamp 800 to change accordingly. In this embodiment, the color-changing temperature measuring patch 600 is disposed on the bus duct body 100. Specifically, the color-changing temperature measuring patch 600 is attached to the groove wall of the groove 310 of the second side plate 300.
[0030] Since the bus duct body 100 is installed in a hanging manner, the groove 310 of the second side plate 300 of the bus duct body 100 will face outward, so that the color-changing temperature measuring patch 600 can be displayed intuitively. In actual use, the color-changing temperature measuring patch 600 is attached to the bus duct body 100. When the temperature of the bus duct body 100 changes, the induction light 800 of the color-changing temperature measuring patch 600 will change accordingly. For example, when the temperature of the bus duct body 100 gradually changes from low to high, the induction light 800 of the color-changing temperature measuring patch 600 will gradually change from the cool blue to the warm red to serve as a warning.
[0031] The temperature sensor 700 is disposed on the bus duct body 100. Specifically, the temperature sensor 700 is attached to the outer surface of the bus duct body 100. The temperature sensor 700 can monitor the temperature of the bus duct body 100 and its surrounding environment. In some embodiments, the temperature sensor 700 is also electrically connected to the sound and light alarm. When the temperature of the bus duct body 100 exceeds a preset threshold, the temperature sensor 700 can control the sound and light alarm to send out a sound and light warning signal to alert the staff on site.
[0032] In the temperature-controlled bus duct provided in the embodiment of the present application, the normal operating temperature of the bus duct body 100 is generally maintained at about 40°C to ensure that 100% of the rated current can operate stably for a long time. The bus duct body 100 can set the allowable temperature rise to 55K. If the temperature rise exceeds 25K, the temperature sensor 700 will control the sound and light alarm to issue an early warning.
[0033] Temperature rise refers to the temperature of the bus duct body 100 that is higher than the ambient temperature. When multiple busbars in the bus duct body 100 are energized, a current thermal effect will be generated. As time goes by, the temperature of the bus duct body 100 continues to rise to a stable state. The stable judgment condition is that the temperature difference before and after all the test points selected on the bus duct body 100 does not exceed 2k within a certain test interval. At this time, the difference between the temperature of any test point and the average ambient temperature of the last 1 / 4 cycle of the test is called temperature rise, and the unit is K.
[0034] At present, the maximum temperature rise of a general bus duct is ≤70K or ≤55K. If the temperature rise of the bus duct can be controlled below ≤55K, not only will the line loss of electric energy be greatly reduced, but also the fire accidents caused by electricity can be reduced, thereby saving energy and reducing emissions, and protecting the safety of the bus duct body 100 itself.
[0035] In this embodiment, the temperature sensor 700 can simultaneously monitor two temperature values of the bus duct body 100: an instantaneous value and an interval value. The instantaneous value refers to the temperature of the bus duct body 100 suddenly reaching a preset threshold, and the interval value refers to the temperature value of the bus duct body 100 slowly changing.
[0036] In the temperature-controlled bus duct provided in the embodiment of the present application, the bus duct body 100 is composed of a first side panel 200, a second side panel 300 and a top panel 400, wherein a color-changing temperature measuring patch 600 is attached to the second side panel 300, and the induction light 800 of the color-changing temperature measuring patch 600 can change with the temperature change of the bus duct. At the same time, a temperature sensor 700 is also provided on the bus duct body 100, and the temperature sensor 700 can control the sound and light alarm to issue a sound and light warning after the temperature of the bus duct body 100 exceeds a preset threshold. With the above-mentioned structural design, the temperature change of the bus duct body 100 can be monitored in real time, so that the staff can deal with safety hazards in a timely manner, thereby greatly avoiding the occurrence of major accidents.
[0037] In some embodiments, Figure 2 As shown, the color-changing temperature measuring patch 600 includes a plurality of sensing lamps 800 . The color-changing temperature measuring patch 600 is a long strip-shaped patch structure. The plurality of sensing lamps 800 are evenly distributed along the length direction of the color-changing temperature measuring patch 600 . The temperature sensor 700 is installed between adjacent sensing lamps 800 .
