Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of distribution transformer monitoring, in particular to a distribution transformer monitoring device. Background Art
[0002] Distribution transformer, referred to as "distribution transformer", refers to a static electrical appliance in the power distribution system that transforms AC voltage and current according to the law of electromagnetic induction to transmit AC power. In some areas, power transformers with voltage levels below 35 kV (mostly 10KV and below) are called "distribution transformers", referred to as "distribution transformers". The place and place where "distribution transformers" are installed is the substation. In order to ensure the stable operation of the components inside the distribution transformer during use, it is necessary to monitor the components inside the distribution transformer.
[0003] At present, the operating status of the internal components of the distribution transformer is mainly monitored by separately installing corresponding monitoring components in the distribution transformer. Although the operating status of the internal components of the distribution transformer can be monitored with the help of the monitoring components, each separately installed monitoring component is mainly used to obtain the operating status information of the internal components of the distribution transformer through on-site observation by staff during use. As a result, the efficiency of obtaining the operating status information of the internal components of the distribution transformer is relatively low, the information acquisition method is relatively single, and the timeliness is poor, which makes it inconvenient to take timely remedial measures when a distribution transformer fails.
