Abstract

The invention relates to an intelligent distribution transformer which is widely applied to daily state operation and maintenance management of distribution transformers, and belongs to the technicalfield of distribution transformers. The intelligent distribution transformer comprises a first iron core, a second iron core and a third iron core which are immersed in transformer oil, wherein threewindings are arranged outside the three iron cores respectively; each of the three windings comprises a high-voltage coil and a low-voltage coil, wherein a high-voltage coil lead of the first windingpenetrates through a first high-voltage current transformer; a low-voltage coil lead of the first winding penetrates through a first low-voltage current transformer; a power supply coil is further wound outside the first winding; the power supply coil supplies power to a rectifying circuit, a filter capacitor, a GPS positioning module, a 4G module, a current collector and a single-chip microcomputer controller; and the current collector is connected to the high-voltage current transformer and the low-voltage current transformer through leads. According to the intelligent distribution transformer, real-time distribution transformer monitoring can be realized, the daily operation and maintenance management efficiency of the distribution transformer is improved, and the human resource cost isreduced.

Description

technical field [0001] The invention relates to an intelligent distribution transformer, which is widely used in the daily state operation and maintenance management of distribution transformers, and belongs to the technical field of distribution transformers. Background technique [0002] The working principle of the intelligent distribution transformer is: by adding 4G, GPS, and temperature modules, the real-time collection of data such as the position, current, voltage, and temperature of the distribution transformer is realized, and the fault is predicted by monitoring the current and voltage changes. Proactively send out alarm information. At present, the existing distribution transformers do not have real-time positioning and fault alarm functions, and cannot reflect the operation status in real time, which affects the efficiency of fault repair. [0003] Therefore, there is an urgent need for an intelligent distribution transformer that can solve the above-mentioned ...
