Fiber optic temperature measurement solutions include fiber optic temperature measurement for power cables, such as cable trench fiber optic temperature measurement and transformer fiber optic temperature measurement. The temperature range of cable joints, cable temperature standards, and cable temperature measurement systems are all of great concern to everyone.

The Importance of Cable Joint Temperature Monitoring System

The causes of multiple high-voltage cable fire accidents in China are mostly due to poor cable joints, resulting in increased contact resistance, which in turn causes the temperature of the joints to rise, leading to even worse joint contact. Without monitoring it, it forms a vicious cycle, ultimately leading to cable fires, causing unexpected losses and losses. ስለዚህ, achieving real-time online temperature monitoring of cables and cable trenches is an important guarantee for the safe operation of enterprises. Cable joints are used for the connection between cable bodies, but have always been a weak link in the operation of cable systems. Among many accidents in high-voltage lines, safety accidents caused by poor contact of cable joints are the most common. The increase in temperature of cable joints increases the contact resistance at the joints, leading to overheating of cable joints, exacerbating insulation aging and even causing insulation breakdown, posing a serious threat to the safe operation of the power system. ስለዚህ, if real-time and effective monitoring of temperature changes during the operation of cable joints can be achieved, it is of great significance to achieve online monitoring of cable joints and improve the safe operation of cable lines.

Why do cable joints need temperature measurement

በኃይል ስርዓት ውስጥ, there are many cable joints, such as bus joints, switch contacts, ወዘተ. Due to the high voltage and high current carried by transmission cables, cable joints are crucial. In high-voltage transmission lines, poor cable joints gradually increase the resistance at the joints, causing the temperature to rise. When the temperature reaches a certain level, the cable joints are burned, resulting in safety accidents. The existing temperature monitoring devices mostly use electronic temperature sensing devices for monitoring. ቢሆንም, due to the high voltage and high current conveyed by cables, electronic sensing devices are prone to electric shock accidents due to the inability to isolate high voltage through wires. ስለዚህ, the application of electronic sensing devices in high voltage and high current temperature monitoring is greatly limited. Although there are fiber Bragg grating temperature sensing devices that can be applied now, the demodulation equipment cost of fiber Bragg grating sensing devices is high and currently difficult to popularize.

What are the traditional methods for temperature measurement of intermediate joints in power cables

አህነ, the temperature measurement method for cable joints mainly uses thermocouples or infrared detection technology to detect the outer surface temperature of cable joints. ቢሆንም, the measurement results obtained by this method are not only easily affected by external environmental temperature and air convection, but also by the interference of strong magnetic fields in the joints, making accuracy difficult to guarantee;
