Wind farm fluorescent fiber temperature measurement, wind power photovoltaic new energy transformer winding temperature control system, oil immersed transformer winding fluorescent fiber temperature control system (wind farm main transformer temperature monitoring).
According to the structure of wind power plants, the application of fluorescent fiber optic temperature measurement technology to wind farm equipment:
Fan grid connected cabinet, frequency conversion cabinet contact temperature measurement, gearbox, and fan stator temperature monitoring. Box transformer temperature monitoring.
Step up station: intelligent monitoring of winding temperature of the main transformer, intelligent monitoring of contact and cable joint temperature of high and low voltage switchgear, and monitoring of cable operation temperature in the station’s cable trench.
The fluorescent fiber optic temperature measurement system can be practically used for temperature measurement in fan grid connected cabinets and frequency conversion cabinets
Fiber optic temperature measurement for the top grid connected cabinet of the fan, input side fiber optic temperature measurement for the grid connected cabinet inside the frequency conversion cabinet, generator stator side fiber optic temperature measurement for the grid connected cabinet, and fiber optic temperature measurement for the contactor on the grid side of the frequency conversion cabinet.
Connect the temperature measuring fiber head and the outgoing cable joint to the copper busbar in a dedicated manner. The fiber is routed along the cable to the installation position of the thermometer and connected to the fluorescent fiber thermometer. The fluorescent fiber thermometer is powered by AC 220V and can achieve local temperature display. Real time temperature data is uploaded to the monitoring software through RS485 communication signals.
Frequency conversion cabinet network side controller temperature measurement host installation fluorescent fiber temperature control system for box type transformers (used for temperature monitoring of wind farm box type transformers)
De fluorescent fiber optic temperature measurement system for box type transformers can directly monitor the hot spot temperature of the transformer, improve the operational safety of the equipment, extend the insulation life of the equipment, instantly judge the actual load capacity of the equipment, and maximize the potential of power transmission and distribution to improve the economic efficiency of the equipment, which is of great significance.
Installation plan for temperature measurement system of box type transformer
The temperature measurement position of the box type transformer is located at the low voltage winding or high voltage winding and iron core position, with a maximum temperature measurement requirement of 200 ℃. Dêrom, a box type transformer temperature measurement optical fiber is designed and combined with a fixed device. During the pouring process of the box type transformer, a temperature measurement hole is reserved. When measuring temperature, the optical fiber is implanted into the temperature measurement hole to directly measure the temperature at the winding position.
Introduction to Fluorescent Fiber Temperature Control System for Oil immersed Transformer Winding (Temperature Monitoring of Wind Farm Main Transformer)
The entire oil transformer fiber optic temperature measurement system mainly consists of a fiber optic temperature measurement host, fluorescent fiber optic sensors, adapter cables, penetrators, flanges, ensfh. The fluorescent fiber optic sensor is directly placed at the heating part of the transformer winding coil, and the flange ensures the sealing of the transformer’s own structure. The other end of the fluorescent fiber optic sensor is connected to the inner and outer sides of the connector on the flange, respectively, to achieve the transmission of optical signals. The other end of the connector is connected to the fluorescent fiber optic thermometer, and the fluorescent fiber optic sensor transmits the optical signal to the temperature measurement host. The temperature measurement host demodulates the received optical signal into a temperature signal, displays it locally, and communicates with the monitoring system through a 485 interface to achieve real-time monitoring of the transformer winding temperature.
De fluorescent fiber temperature control system for high-voltage switchgear is equipped with a fiber optic thermometer installed in the secondary room of the switchgear. The temperature measuring fiber is usually installed at the static contact and cable joint.
