Description

Technical Field

[0001] The utility model relates to the field of power engineering, in particular to a real-time temperature safety monitoring device for bus ducts. Background Technique

[0002] In modern power engineering, bus duct systems are widely used in high-rise buildings, industrial plants and other places. Temperature monitoring of bus ducts is an important link to ensure their safe operation.

[0003] At present, the common temperature monitoring methods for bus ducts on the market mainly use ordinary fiber optic temperature measurement hosts at the meter level. After a 3-meter fiber optic coil is wound and then attached to the bus bar and fixed with tape. However, this method has the following several significant disadvantages:

[0004] By winding a 3-meter fiber optic coil to increase the temperature sensing area of the optical cable, it is very wasteful of the optical cable, and the construction difficulty is relatively large, with high requirements for the technical level of workers, and it is easy to have improper installation. In addition,

[0005] Using the method of fixing the connection between the 3-meter fiber optic coil and the bus bar with tape is easy to fall off after long-term use, resulting in the optical fiber not being able to stably adhere to the bus bar, affecting the accuracy and reliability of temperature measurement. Content of the Utility Model

[0006] Aiming at the deficiencies of the prior art, the utility model provides a real-time temperature safety monitoring device for bus ducts, which solves the problems of optical cable waste and easy detachment existing in the traditional cooperation with a 3-meter fiber optic coil.

[0007] To achieve the above object, the utility model is realized through the following technical solutions: A real-time temperature safety monitoring device for bus ducts, including a fiber optic temperature measurement host, one side of the fiber optic temperature measurement host is connected with a temperature sensing optical fiber, the temperature sensing optical fiber is arranged on the upper surface of the bus bar, a bus duct is arranged on the upper surface of the bus bar, the temperature sensing optical fiber is distributed in a sine wave shape on the upper surface of the bus duct, U-shaped clamps are arranged at both the wave crest and wave trough of the temperature sensing optical fiber, a fiber optic groove is opened on the lower surface of the U-shaped clamp, the temperature sensing optical fiber passes through the U-shaped clamp through the fiber optic groove, magnetic attraction sheets are fixedly connected to both sides of the lower surface of the U-shaped clamp, and the U-shaped clamp is adsorbed on the upper surface of the bus bar through the magnetic attraction sheets.

[0008] Preferably, four fiber optic protection pads are evenly distributed inside the fiber optic groove.

[0009] Preferably, the fiber optic protection pad is semi-circular, and the material of the fiber optic protection pad is silicone rubber.

[0010] Preferably, a plurality of heat dissipation holes are opened between the fiber optic groove and the U-shaped clamp.

[0011] Preferably, the depth of the fiber optic groove is 3 mm.

[0012] Preferably, a temperature display screen is provided on the outer surface of the optical fiber temperature measurement host. Advantages

[0013] The utility model provides a real-time temperature safety monitoring device for busbars. Compared with the prior art, it has the following advantages:

[0014] In the utility model, through the provided U-shaped clamps, before monitoring the temperature of the busbar, the temperature-sensitive optical fiber is passed through the optical fiber grooves of the four U-shaped clamps, and then the four U-shaped clamps are adsorbed on the upper surface of the busbar in a sine wave form. It is not easy to fall off after long-term use, ensuring that the optical fiber is stably attached to the busbar. In addition, there is no need to wind a 3-meter-long optical fiber coil, greatly reducing the amount of optical cable used and improving the utilization efficiency of the optical cable. Compared with the linear arrangement, the sine wave arrangement increases the contact area between the temperature-sensitive optical fiber and the surface of the busbar, reduces the existence of blind spots, and ensures that the temperature of the entire busbar can be monitored;

[0015] 2. In the utility model, through the provided optical fiber protection pad and heat dissipation holes, the optical fiber protection pad is made of semi-circular silicone rubber material, which can effectively absorb and disperse the impact and pressure from the outside on the optical fiber, reducing the possible physical damage to the optical fiber during installation and operation. The optical fiber protection pads are evenly distributed inside the optical fiber grooves, which helps to fix the position of the optical fiber, prevent the optical fiber from moving in the grooves, and ensure that the optical fiber remains stable in the U-shaped clamps, thereby improving the accuracy of temperature measurement. The multiple heat dissipation holes opened between the optical fiber grooves and the U-shaped clamps help to improve the heat dissipation efficiency, prevent temperature measurement errors caused by heat accumulation, and also help to extend the service life of the optical fiber and the clamps.

One side of the optical fiber temperature measurement host 1 is connected to a temperature-sensing optical fiber 2, and the specific model of the temperature-sensing optical fiber 2 is WT-GL-101. During the operation of the busbar 3, the temperature change of the busway 9 is sensed in real time by the temperature-sensing optical fiber 2 laid on the surface of the busway 9, and the temperature information is converted into an optical signal, which is fed back to the optical fiber temperature measurement host 1 and is displayed in real time through the temperature display screen 10, realizing the real-time monitoring of the temperature of the busway 9. The temperature-sensing optical fiber 2 is arranged on the upper surface of the busbar 3, and a busway 9 is arranged on the upper surface of the busbar 3. The temperature-sensing optical fiber 2 is distributed in a sine wave shape on the upper surface of the busway 9. U-shaped fixtures 4 are arranged at both the wave crest and wave trough of the temperature-sensing optical fiber 2. An optical fiber groove 5 is opened on the lower surface of the U-shaped fixture 4, and the temperature-sensing optical fiber 2 passes through the U-shaped fixture 4 through the optical fiber groove 5. Magnetic sheets 6 are fixedly connected to both sides of the lower surface of the U-shaped fixture 4, and the U-shaped fixture 4 is adsorbed on the upper surface of the busbar 3 through the magnetic sheets 6.

[0025] During operation, before monitoring the temperature of the busway 9, the temperature-sensing optical fiber 2 is passed through the optical fiber grooves 5 of the four U-shaped fixtures 4, and then the four U-shaped fixtures 4 are adsorbed on the upper surface of the busway 9 in a sine wave shape. It is not easy to fall off after long-term use, ensuring that the optical fiber is stably attached to the busbar. In addition, there is no need to wind a 3-meter-long optical fiber coil, greatly reducing the amount of optical cable used and improving the utilization efficiency of the optical cable. Compared with the linear arrangement, the sine wave arrangement increases the contact area between the temperature-sensing optical fiber 2 and the surface of the busway 9, reducing the existence of blind spots and ensuring that the temperature of the entire busway 9 can be monitored.

The optical fiber protection pads 8 made of semi-circular silicone rubber can effectively absorb and disperse the impact and pressure from the outside on the optical fiber, reducing the possible physical damage to the optical fiber during installation and operation. The optical fiber protection pads 8 are evenly distributed inside the optical fiber groove 5, which helps to fix the position of the optical fiber, prevent the optical fiber from moving in the groove, and ensure that the optical fiber remains stable in the U-shaped fixture 4, thereby improving the accuracy of temperature measurement. A plurality of heat dissipation holes 7 are provided between the optical fiber groove 5 and the U-shaped fixture 4.
