When procuring a transformer oil chromatography online monitoring device, questions often arise regarding whether the detection cycle can be adjusted, data storage duration, and the lifespan of core components. The following explains the DRD-8100 transformer oil chromatography online monitoring device from a practical configuration perspective, for selection reference.
The device's default detection cycle is 24 hours per test. Users can set it to 6 hours per test or 12 hours per test according to on-site operation and maintenance requirements. Cycle adjustment is completed through local or remote configuration, with no need to replace hardware.
Monitoring data storage time is no less than 10 years, meeting the needs of long-term trend analysis. The designed lifespan of the permeable membrane is 8 years, the chromatographic column lifespan is 6 years, and the sensor lifespan is 10 years. The above lifespan indicators are based on conventional operating environments; actual replacement cycles can be evaluated in combination with oil quality conditions and usage frequency.
The device's operating ambient temperature starts from -40°C, making it suitable for outdoor installation scenarios at northern substations in winter. The internal gas path and temperature control unit are adapted for low-temperature conditions, and after startup it can enter a stable detection state within the specified time.
The system adopts a modular structure and is mainly composed of an oil circuit circulation unit, a degassing unit, a chromatographic separation unit, a detector, and a data processing unit. The device can be wall-mounted or floor-mounted near the main transformer, connected to the transformer oil sampling port through flanges or pipelines, and supports communication methods such as RS485 and Ethernet to connect to the backend system.
