Abstract

The invention provides an intelligent distribution transformer which can transfer information such as electric quantity of a user and the like to a smart grid according to energy flow analysis of the transformer. In the invention, the transformer is equipped with a single-chip microprocessor intelligent device, and the intelligent device and the transformer form an electrical signal connection through an electric quantity sensor and a status sensor which are arranged on the transformer so as to detect the energy flow and operating status of the transformer; the generated signals are delivered to an intelligent unit for analysis processing to obtain various electric quantity information of the user and the status information of the transformer; and the relevant information is intercommunicated with the smart grid through a communication module. The intelligent distribution transformer has the advantage that various electric quantity parameters of the user and the state quantity of the transformer can be intercommunicated with the smart grid.

Description

Technical field: [0001] The invention relates to a distribution transformer, which belongs to the field of electric equipment, in particular to a smart distribution transformer. Background technique: [0002] The distribution transformer is an important pivotal component in the distribution network.
