How to measure temperature of wind farm transformer switchgear-INNO

Вимірювання температури флуоресцентного волокна вітрової електростанції, вітроенергія фотоелектрична нова система контролю температури обмотки трансформатора енергії, система контролю температури флуоресцентного волокна з обмоткою масляного трансформатора (моніторинг температури основного трансформатора вітрової електростанції).

За будовою вітрових електростанцій, застосування флуоресцентної волоконно-оптичної технології вимірювання температури до обладнання вітрової електростанції:
Шафа, з’єднана з вентиляторною сіткою, вимірювання контактної температури в камері перетворення частоти, коробка передач, і контроль температури статора вентилятора. Контроль температури коробкового трансформатора.
Підвищити станцію: інтелектуальний моніторинг температури обмотки головного трансформатора, інтелектуальний моніторинг температури контактів і кабельних з'єднань розподільних пристроїв високої та низької напруги, та контроль температури експлуатації кабелю в кабельній траншеї станції.

The флуоресцентна волоконно-оптична система вимірювання температури 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)

The 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 ℃. тому, 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 волоконно-оптична система вимірювання температури mainly consists of a fiber optic temperature measurement host, флуоресцентні волоконно-оптичні датчики, adapter cables, penetrators, фланці, тощо. 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, відповідно, 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.

The 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.
