The characteristics of DTS განაწილებული ბოჭკოვანი ტემპერატურის გაზომვის სისტემა
The smart grid of the power system includes power plants, high-voltage grids, substations, distribution stations, და ა.შ., specifically including generators, ტრანსფორმატორები, power cables, switches and other power equipment. Power equipment usually operates in environments such as high voltage, strong electric fields, and heat loads, and the working environment is unmanned and unmonitored. As an engineering infrastructure, the smart grid involves the electricity needs of thousands of households, and the operating temperature of power equipment is an important factor in ensuring the safe operation of the smart grid. Whether it is transformers, power cables, or other power equipment, as important components of the power system, they may cause local overheating or arc sparks due to some circuit problems or external factors, leading to fires and causing losses to people’s production and life. ამიტომ, in order to avoid such a malignant event, it is urgent to conduct comprehensive temperature monitoring of power equipment. For cable tunnels used to accommodate a large number of cables laid on cable supports in corridors or tunnel structures, the environmental temperature and cable operating conditions can only
When a malfunction occurs, it is found that the longer the operating time, the more prone it is to overheating and burning accidents, which may cause huge economic losses.
Application of distributed fiber optic temperature measurement system in fiber optic temperature sensors
The existing electronic temperature sensors use point type temperature measurement, which is prone to electromagnetic interference and is not suitable for strong electromagnetic scenarios, while fiber optic temperature sensors are not affected by electromagnetic interference and are very suitable for temperature monitoring in power systems. Fiber optic temperature sensors include single point temperature sensors and quasi distributed fiber optic temperature sensors. A single point temperature sensor measures a certain point in the temperature field with high measurement accuracy and reliability, but it is difficult to measure the distribution of multiple points in the temperature field. To solve the measurement problem of temperature field multi-point distribution, a quasi distributed fiber optic temperature sensor composed of a multiplexed fiber optic temperature sensor and an array of fiber optic temperature sensors has emerged. The quasi distributed fiber optic temperature sensor uses a single point fiber optic sensor array to form a spatial network distribution, achieving distributed fiber optic temperature measurement.
Distributed fiber optic thermometer is an optical time-domain temperature monitoring system, which is a widely used distributed fiber optic temperature measurement system both domestically and internationally. The system consists of a temperature measurement host, temperature sensing fiber optic, and DTS backend analysis software.
The distributed temperature measurement fiber optic system is based on the principle of Raman scattering in light, integrating optical time-domain reflection (OTDR) technology and the temperature sensitive characteristics of scattered light. It detects temperature changes at different positions along the fiber optic and achieves truly distributed measurement through intelligent analysis of DTS backend software data. It can continuously measure the temperature at any point along the fiber optic.
The characteristics of distributed fiber optic temperature measurement system
The measurement distance of the distributed fiber optic temperature measurement system ranges from a few kilometers to several tens of kilometers, and the spatial positioning accuracy can reach the level of 1m. It can conduct uninterrupted real-time online monitoring and transmit real-time data remotely, timely warning of fire hazards, and accurately locate the location of the fire. It can achieve distributed real-time measurement of temperature in a wide range of space, with advantages such as long measurement distance, no measurement blind spots, real-time monitoring, and precise positioning. It is widely used in fields such as transportation tunnels, subways, ძალაუფლება, petrochemicals, and water conservancy.
