Q: Under what circumstances should an oil chromatography online monitoring system be configured in substation design and selection?
A: When transformers are located in remote areas, manual sampling cycles are long, or continuous tracking of dissolved gas trends in oil is required, an online monitoring system can serve as a supplementary means to routine sampling detection. The ES-2010 oil chromatography online monitoring system is suitable for such scenarios. Its default detection cycle is 24 hours per test, and it can also be set to 6 hours per test or 12 hours per test as needed, making it convenient for designers to configure flexibly according to monitoring density requirements.
Q: How should the installation and operation of the system in harsh environments be considered?
A: During design and selection, it is necessary to distinguish between indoor and outdoor installation components. The main station unit of the ES-2010 is an indoor installation component with a protection rating of IP51; this system and the communication control unit are outdoor installation components with a protection rating of IP56. The operating ambient temperature covers -40°C to +55°C, and the extreme storage and transportation ambient temperature is -40°C to +80°C, allowing it to adapt to the climatic conditions of most outdoor substations. Outdoor components should avoid long-term water accumulation or highly corrosive gas environments; otherwise, monitoring accuracy may be reduced or equipment life may be shortened.
Q: How do the lifespans of key consumables and components affect long-term operation and maintenance?
A: The permeation membrane lifespan is 8 years, the chromatographic column lifespan is 6 years, and the sensor lifespan is 10 years. During design and selection, these parameters can be used to estimate maintenance costs and spare parts plans over the full life cycle. It should be noted that if on-site oil quality is abnormal or temperature fluctuates sharply, the actual lifespan may be lower than the nominal value. The data storage capacity is no less than 10 years, which can meet long-term trend analysis needs.
Q: How should dimensions and installation space be checked during selection?
A: The external dimensions are 600 mm in width; the specific depth and height need to be confirmed in combination with the actual layout of the main station unit and outdoor components. During the design stage, sufficient maintenance access should be reserved, and the installation position of outdoor components should ensure convenient laying of communication cables. Violating installation space requirements or exceeding environmental limits may lead to reduced system monitoring accuracy, or even damage to equipment or unnecessary injury.
Q: What operational precautions should be taken during on-site use?
A: Do not forcibly operate under conditions exceeding the specified temperature range or with insufficient protection rating; do not arbitrarily disassemble the permeation membrane, chromatographic column, or sensor; do not plug or unplug communication or power interfaces without cutting off power. The above operations may reduce system monitoring accuracy, endanger system service life, or damage this system and other user equipment. Design and selection personnel should clarify installation conditions and operational boundaries in the technical agreement to avoid misoperation during later operation and maintenance.
