Innotranslate Oil Temperature, Oil Level, and Pressure Monitoring Solution

Inotera has been deeply engaged in the field of power equipment monitoring for many years, and itsIB-YKTCF-OL/OP Type Oil Temperature, Oil Level and Pressure Monitoring SystemIt is the core product researched and developed for intelligent distribution transformers and combined substations, which has overcome the pain points of traditional monitoring of false oil level, unsynchronized data, and inability to remote warning, and has been widely used in intelligent substations, wind farms, photovoltaic power stations, and industrial power plants, and it is the preferred product for oil temperature and oil level and pressure monitoring in China at present.

3.1 Core Product Parameters (Precise Monitoring, Full Condition Adaptation)

  1. Oil temperature measurement: range - 45.0℃～200.0℃, -45℃～100℃ accuracy ±2℃, resolution 0.1℃, data update ≤0.2s;
  2. Pressure measurement: Absolute pressure 71～181Kpa, accuracy ±2Kpa, resolution 1Kpa, can accurately monitor the pressure changes inside the transformer;
  3. Oil level measurement: range 0～-35mm, accuracy ±2mm, resolution 1mm, completely eliminate the false oil level problem affected by oil temperature;
  4. Communication function: support Modbus, IEC61850 mainstream protocols, RS485 communication interval ≥ 0.2s, can be accessed to the station intelligent fusion terminal.

3.2 Core product strengths

  1. Three-in-one integrated design: one device realizes full parameter monitoring of oil temperature, oil level and pressure, reduces installation points and maintenance workload, and lowers equipment investment costs;
  2. High reliability: protection level IP68, adapt to outdoor high temperature, high humidity, dusty environment, through the power industry a number of authoritative certification;
  3. Wide adaptability: can be directly retrofitted to the old transformer, no need to replace the body, to realize the intelligent upgrading of the traditional transformer, can also be supplied with new transformers.

3.3 Typical application scenarios

  • Intelligent substation: realizing comprehensive sensing of transformer status and supporting the construction of unattended operation and maintenance system for power grid;
  • New energy power stations: wind farms, photovoltaic power stations remote site transformer remote monitoring, reducing the cost of manual inspection;
  • Industrial enterprises: real-time monitoring of key transformers in steel and chemical captive power plants to ensure production continuity;
  • Urban and rural distribution network: intelligent transformation of 10kV/35kV distribution network transformers, and access to intelligent fusion terminals in suitable stations.

FAQ：Transformer oil temperature oil level pressure monitoring FAQs

Q1：Why should I choose the integrated oil temperature and oil level and pressure monitoring equipment instead of monitoring the oil level separately?

A: Individual monitoring of oil level is susceptible to false oil level due to thermal expansion and contraction of oil temperature, integrated monitoring can determine the status of the equipment through multi-parameter linkage: oil level drop + pressure reduction = oil leakage, oil level rise + oil temperature surge = internal failure, which can accurately identify the real failure and avoid equipment damage caused by misjudgment.

Q2：How does Inotera's 3-in-1 monitoring device interface with the existing power monitoring system?

A: The product supports Modbus, IEC61850 and other standard communication protocols, through the RS485 interface can be directly accessed to the SCADA system, substation automation system or third-party cloud platform, without additional development of interfaces, strong compatibility, adaptable to the domestic mainstream monitoring system.

Q3：How is the after-sales service of Inotera products?

A: the establishment of a number of service outlets across the country, to provide 7 × 24 hours technical support, on-site fault response time ≤ 48 hours, while providing equipment calibration, operation training services.

Q4：How to select transformer oil temperature and oil level pressure monitoring equipment?

A: according to the transformer voltage level, installation environment, communication needs selection: 10kV/35kV distribution network transformer priority selection of Inotera IB-YKTCF-OL/OP type three-in-one device; large power station 220kV and above transformers can be customized according to the needs of upgrading the monitoring function; outdoor harsh environments need to choose ≥ IP65 protection level of the device.
