MOBILE INSTRUMENT-ANALYTICAL SYSTEM FOR POWER TRANSFORMER DIAGNOSTIC MONITORING Russian patent published in 2025 - IPC G01R31/62 

FIELD: measuring.

SUBSTANCE: invention relates to systems for monitoring the technical state of transformer equipment of power stations and substations and can be used for diagnostic monitoring of oil-filled electrical devices, for example, power transformers. Mobile instrument-analytical system for diagnostic monitoring of a power transformer includes a van based on an automobile trailer with a double-sided post. Post accommodates a transformer oil gas-moisture analysis unit, a wireless communication unit connected to the transformer oil gas-moisture analysis unit, a power supply control unit for feeding the transformer oil gas-moisture analysis unit, and a wireless communication unit. Wireless communication unit is configured to provide communication with a remote automated workstation and a terminal cabinet. Terminal cabinet is connected to the main control panel of the power transformer and is designed to convert analogue signals from the main control panel of the power transformer into a digital form and transmit the converted signals to a wireless communication unit. Complex also contains shutoff valves intended for hydraulic connection of gas-moisture analysis unit of transformer oil with power transformer, and a remote automated workstation based on a computer, equipped with a wireless communication module and configured to use at least one of the mathematical models stored in its memory, intended for calculating the characteristics of the power transformer based on data transmitted from the gas-moisture analysis unit and from the main control panel through the unit wireless communication.

EFFECT: wider range of technical means for diagnostic monitoring of a power transformer and faster movement of the diagnostic complex between electric power facilities and performance of preparatory work before its commissioning.
