Sensor de temperatura de fibra óptica, Sistema de monitoreo inteligente, Fabricante de fibra óptica distribuida en China
Con la implementación de la renovación de la red eléctrica, especialmente la continua profundización de la renovación y construcción de la red urbana, the usage of cables and electrical equipment has significantly increased, lo que ha hecho que la gestión de la operación, Monitoreo y mantenimiento de cables y equipos eléctricos muy importante. En el trabajo práctico, para evitar que los cables y los equipos eléctricos se sobrecalienten a altas temperaturas, Por lo general, es necesario elegir un método que conserve adecuadamente su capacidad de carga. Sin embargo, Esto hace que el uso de estos cables y equipos eléctricos sea antieconómico, and manual inspections can only detect the surface temperature of the test point. Para equipos eléctricos cerrados, como cables y aparamenta, No se puede lograr un verdadero monitoreo de la temperatura. Whether from the perspective of the safe operation of electrical equipment such as cables and ring main cabinets or from the perspective of power system scheduling needs, Se requiere monitoreo en tiempo real de la capacidad de carga de cables y equipos eléctricos, which can be achieved through online real-time monitoring of the temperature of the test points.
The reliability of high-voltage switchgear under high voltage and high current conditions is closely related to the temperature rise of the isolation switch contacts. During the operation of the power grid, mechanical vibration, contact erosion, and other reasons can worsen contact conditions, increase contact resistance, cause an increase in contact point temperature, exacerbate contact surface oxidation, and lead to local welding or arc discharge at loose contact points, ultimately causing damage to electrical equipment, Cortes de energía, or major accidents such as fires. This type of contact overheating fault accident is not only due to the quality problem of the high-voltage cabinet switch itself, but more importantly, due to the lack of effective monitoring methods for the temperature rise of the isolation switch contacts at present.
Regarding the operation of contact temperature in high-voltage switchgear and cable branch boxes, by measuring, monitorización, and statistically analyzing the temperature of branch boxes, switchgear or high-voltage contacts using fluorescent fiber optic contact, operators can comprehensively grasp the working conditions of branch boxes, switchgear or high-voltage contacts, and avoid or reduce the occurrence of faults; The high-voltage power temperature measurement system has good reliability and complete functions.
