H201CI-1 201 series on-line monitoring system for gas in transformer oil
The H201CI-1 201 series on-line monitoring system for gas in transformer oil is a product developed by HYDRAN. The system is divided into two parts: the sensor unit H201Ti and the communication unit H201Ci-1. The principle is that the dissolved gas in the oil passes through the selective permeable membrane into the electrochemical gas detector (sensor), in the sensor, H2, CO, C2H2, C2H4 these gases react chemically with the sensor fuel cell to produce an electrical signal proportional to the reaction rate. Specifically H2×100%+CO×15%+C2H2×8%+C2H4×1%, the output electrical signal is rectified and amplified, and the volume fraction of 1×10-6 is displayed.
In addition, Wuhan Gamwei Technology Co., Ltd. has also launched a comprehensive online monitoring system for dissolved gas in transformer oil and winding temperature rise, which combines advanced semiconductor laser technology and photoacoustic spectroscopy technology well for gas monitoring in transformer oil.
