Research on intelligent sensing terminal technology of a distribution transformer for ubiquitous power internet of things

With the construction of the ubiquitous power internet of things, new requirements on the equipment of the sensing layer have been put forward. In view of the current shortage of low-capacity distribution transformers that cannot perceive the information of a high-voltage incoming line, a new intelligent sensing terminal design technology for distribution transformers is proposed. The intelligent sensing terminal consists of high voltage sensing ontology and an intelligent measuring terminal. The voltage and current on the high voltage side of the distribution transformer can be accurately determined using the high voltage sensing ontology; through the use of the edge computing function of the intelligent measurement terminal, the monitoring of distribution transformer status and the detection of distribution line information can be effectively realized. The key sensing technology of high voltage sensing ontology is analyzed, and the sensor accuracy is tested; the common edge computing technologies of the intelligent measurement terminal are analyzed. The intelligent sensing terminal can effectively meet the sensing requirements of a distribution transformer for the power internet of things, so it has a broad application prospect.
