Description
BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to electric power supply, and more particularly, to a bus duct for measuring internal temperature and internal humidity and a power supply system including the same.
Bus ducts, whose energy losses are relatively low compared to cables, are commonly used in installations that typically require large amounts of power. In addition to this original purpose, the booth duct is unique in that it is easy to maintain and repair. In particular, by measuring the temperature inside the booth duct, it is possible to know indirectly whether or not unintended power consumption (for example, short circuit) exists in the booth duct.
Therefore, the following prior art documents analyze the passing light of the optical fiber installed along the bus duct to measure the internal temperature of the bus duct. However, there is a disadvantage that the following prior art documents are not economical because optical fibers having a relatively high cost should be installed separately, and a separate device for realizing light separately from the bus duct must be provided.
On the other hand, one of the causes of defects in the booth duct is the moisture penetrated into the booth duct. The moisture penetrating the booth ducts not only accelerates the corrosion of the booth ducts, but also can short-circuit current-carrying busbars, so the user needs to pre-detect the moisture present in the booth ducts.

At least one or more inspection booth ducts 430-1 and 430-2 may be connected between the bus ducts 410-1, 410-2 and 410-3. For example, the bus ducts 410-1, 410-2, and 410-3 can be manufactured by connecting mass produced unit bus ducts in situ, wherein the inspection booth ducts 430-1 and 430-2 May be connected between the unit bus ducts. The higher the ratio of the inspection booth ducts 430-1 and 430-2 in the
The inspection booth ducts 430-1 and 430-2 may include a second bus bar, a second enclosure, and a status indicator.
The second booth bar may be connected to the first booth bar included in each of the booth ducts 410-1, 410-2, and 410-3. The second bus bar can be electrically connected between the first bus bars, and the current flowing in the first bus bar can continue to flow through the second bus bar.
The second busbar may include a conductor. Conductors included in the second busbar may carry current. The conductor may comprise a metal capable of minimizing power losses occurring in current flowing through the second busbar.

One surface of the status display portions 435-1 and 435-2 can touch the inside of the second enclosure and the other surfaces of the status display portions 435-1 and 435-2 can touch the outside of the second enclosure. Therefore, the status display portions 435-1 and 435-2 can measure the internal temperature and the internal humidity of the second enclosure, and the status display portions 435-1 and 435-2 can transmit the measurement result to the outside of the second enclosure Can be displayed.
The status indicators 435-1 and 435-2 may include at least one of a temperature sensor and a humidity sensor for measuring at least one of the internal temperature of the second enclosure and the internal humidity. As a result, the status display units 435-1 and 435-2 can measure the internal temperature of the second enclosure based on the temperature sensor, and the status display units 435-1 and 435-2 So that the internal humidity of the second enclosure can be measured. In one embodiment, the status indicators 435-1 and 435-2 may include a temperature measurement unit, a humidity measurement unit, and an identification window. In another embodiment, the status display portions 435-1 and 435-2 may include a temperature measurement portion, a humidity measurement portion, and a display portion.
In one embodiment, the temperature measuring section may be discolored when the internal temperature of the second enclosure is above a predetermined temperature. To this end, the temperature measuring part may be located inside the second enclosure. The temperature measuring part may be a reversible temperature indicating label.
Since the color of the reversible temperature indication label can be reversibly changed as the internal temperature of the second enclosure changes, a warning color can be displayed when the internal temperature of the second enclosure is above a predetermined temperature, Is less than the predetermined temperature, the color other than the warning color can be displayed. For example, the reversible temperature indication label may include a portion where a color-changing substance is applied according to the internal temperature of the second enclosure, and a portion where the substance is not applied. When the internal temperature of the second enclosure is higher than a predetermined temperature, the color of the portion to which the substance is applied is changed to a warning color, which is contrasted with the other portions, so that the internal temperature of the second enclosure can be measured.
In another embodiment, the temperature measuring unit can measure the internal temperature inside the second enclosure to generate a temperature measurement signal. For example, the temperature measuring part may include an electronic device with high precision.
In one embodiment, the humidity measuring part may be discolored when the internal humidity of the second enclosure is higher than a predetermined humidity. To this end, the humidity measuring part may be located inside the second enclosure. The humidity measuring part may be a reversible humidity indicating label.
Since the color of the reversible humidity indicator label can be reversibly changed as the internal humidity of the second enclosure changes, a warning color can be displayed when the internal humidity of the second enclosure is higher than a predetermined humidity, and the internal humidity of the second enclosure Is less than the preset humidity, the color other than the warning color can be displayed.
In another embodiment, the humidity measuring unit may measure the internal humidity inside the second enclosure to generate a humidity measurement signal. For example, the humidity measuring part may include an electronic device with high precision.
In one embodiment, the confirmation window can be generated so that the measurement results can be verified outside the second enclosure. That is, the confirmation window can be generated so that the temperature measurement unit and the humidity measurement unit can be confirmed from the outside of the second enclosure. To this end, the confirmation window may include a material through which light is transmitted. The confirmation window can be made of flame retardant material. In other words, the confirmation window may include a material having a sufficiently high ignition point to prevent ignition even when the temperature of the inspection booth ducts 430-1 and 430-2 rises. For example, the confirmation window can be made of chromoprene rubber, which is a flame retardant rubber.
In another embodiment, the display unit may display the measurement result outside the second enclosure based on at least one of the temperature measurement signal generated by the temperature measurement unit or the humidity measurement signal generated by the humidity measurement unit. For example, the display unit may display the internal temperature outside the second enclosure based on the temperature measurement signal, and may display the internal humidity outside the second enclosure based on the humidity measurement signal.
Accordingly, the status display units 435-1 and 435-2 can detect whether or not an excessive current flows due to a short circuit to the first bus bar and the second bus bar, and can prevent moisture from flowing into the first and second enclosures It is possible to detect whether or not it has been introduced.
The first bus bar and the second bus bar in which the short circuit is generated can generate a lot of heat by the excessive current. Therefore, the status display units 435-1 and 435-2 can detect whether an excessive current flows in the first bus bar and the second bus bar by measuring the internal temperature of the second enclosure. In addition, when moisture is introduced into the first enclosure and the second enclosure, the internal humidity of the second enclosure can be increased by such moisture. Therefore, the state indicators 435-1 and 435-2 can measure whether or not moisture has flowed into the first enclosure and the second enclosure by measuring the internal humidity of the second enclosure.
