With the development of science and technology and market economy, intelligent control is becoming increasingly popular. The requirements for electricity capacity, power supply quality, and guarantee ability in residential life, enterprise production, public places, போன்றவை. are becoming higher and higher. The rated current of substation equipment and control equipment is also constantly increasing; Smart grid is a forward-looking trend, and the intelligence of power equipment is the foundation of smart grid. Substation equipment, control equipment, and electrical equipment are generally connected through the main busbar. The intelligence and standardization of temperature monitoring in the busbar power supply system are the basis for real-time transmission status, temperature conditions, and even patrol detection of power. சக்தி அமைப்பில், intelligent busbars will experience a temperature increase when the load current is too high, and the temperature may eventually deteriorate the performance of adjacent insulation components. எனவே, people will install a temperature measurement device for intelligent busbars
With the continuous improvement of industrialization in our country, the electricity consumption in various industries has sharply increased. Traditional cables can no longer meet the requirements of high current transmission, especially in the power transmission of high-rise buildings, large factories, and public facilities. The parallel use of multiple cables has brought many inconveniences to on-site installation and construction connections. Compared to traditional cables, bus ducts have significant advantages in wiring, நிறுவல், and structure.
The components of the busbar duct and the importance of temperature monitoring
Bus duct is a system composed of metal plates as protective shells, conductive bars, insulation materials, and related accessories. In the manufacturing process of bus ducts, manufacturers strive to adopt new technologies and processes to improve the safety and reliability of bus ducts, and the connection between two bus ducts is a key link that affects the safe operation of bus ducts. The connection part is fixed in the plug-in junction box, and by monitoring the temperature of the busbar, the operation status of the busbar duct can be understood, thereby improving the reliability of the busbar duct operation. The common busbar temperature measurement device is usually installed through a series of steps, fixed in the plug-in junction box, and the installation and disassembly process is complex and the connection is unreliable.
Specification for operating temperature of busbars
The allowable temperature for the busbar and switch is 700 °C, and there should be no overheating during operation. The temperature test piece should not melt; The maximum allowable temperature for enclosed busbars is 900 °C, the allowable temperature for the casing is 650 °C, and the allowable temperature for busbar joints is not more than 1050 °C.
How high temperature can the busbar joint withstand?
The allowable operating temperature of the busbar joint is 70 ° C (when the ambient temperature is+25 ° C). If there is a tin coating on the contact surface (such as ultrasonic tin coating), it is allowed to be raised to 35 ° C, and it is allowed to be raised to 100 ° C during flash welding.
The method of temperature measurement for busbars is as follows: (1) Color changing paint. (2) Test the temperature of the wax slice. (3) Semiconductor point thermometer (charged temperature measurement). (4) Infrared measuring instrument. (5) ஃபைபர் ஆப்டிக் வெப்பநிலை அளவீட்டு அமைப்பு
The busbar joint can use a fluorescent fiber optic temperature measurement system, and the busbar trunking bridge can use a distributed fiber optic temperature measurement host. The temperature measurement methods used in different application scenarios are different.
The power bus temperature measurement device and system relates to the field of power device temperature measurement technology, including a fiber optic temperature measurement host and a temperature sensing optical fiber set inside the power bus, with one end of the temperature sensing optical fiber connected to the fiber optic temperature measurement host; The temperature sensing fiber optic sends the sensed temperature data to the fiber optic temperature measurement host, which obtains the bus temperature based on the temperature data. Set the temperature sensing optical fiber inside the busbar, closer to the busbar, and unaffected by external environmental temperature, making temperature measurement more accurate.
