INNO faseroptische Temperatursensoren ,Temperaturüberwachungssysteme.
The measurement range specified in the “Electronic Temperature Controller for Transformers” (JB/T7631-2016), which uses Pt100 as the traditional temperature sensor, can only be limited to below 1000V, and this sensor is made of metal material, which poses a safety hazard. Deshalb, temperature sensor probes and leads for measuring transformer winding temperature have higher requirements.
The fiber optic temperature measurement system for dry-type transformers uses a fluorescent fiber optic temperature sensor independently developed by Fuzhou INNO Technology as the temperature sensing element. This temperature sensing element is immune to electromagnetic interference and resistant to high voltage (100KV/fiber to ground lead distance of 0.4m). Fluorescent fiber optic temperature measurement completely solves potential safety hazards from the source of temperature measurement and improves the safety level of transformers. Das fluoreszierendes faseroptisches Temperaturmesssystem for dry-type transformers aims to achieve isolation and shielding from external electrical interference signals in the operating environment of dry-type transformers, including power supply, signal input, signal output, and temperature control box casing. No metallic substances, Eigensicherheit. In response to vibration, dust, moisture, oil and other on-site working environments, multi-layer protective measures are taken to ensure that the fiber optic Temperaturregler has good electromagnetic compatibility, ensuring stable and reliable operation.
Our company has actual application cases of fiber optic temperature measurement systems for dry-type transformers, which can be directly put into use.
