Abstract

The invention discloses an intelligent transformer. The intelligent transformer comprises a transformer body, a data collecting device installed on the transformer body, an intelligent assembly and a communication module, wherein the intelligent assembly and the communication module are connected with the data collecting device and are connected. The intelligent assembly comprises a transformer monitoring main control unit, a comprehensive measuring unit, an oil chromatogram and micro-water monitoring unit, a partial discharge monitoring unit, an iron core grounding current monitoring unit, an acoustic fingerprint monitoring unit, a transformer sleeve insulation monitoring unit and an on-load voltage regulation switch monitoring unit. The data collecting device is installed on the transformer body in a matched mode and transmits collected related data to the intelligent assembly, the intelligent assembly compares the received data with preset data, remotely transmits a comparison result to a dispatching center through the communication module, gives an alarm at the same time and indicates fault causes and fault points, and therefore the dispatching center can maintain the transformer in time to ensure stable operation of a power grid.

Description

technical field [0001] The invention relates to the technical field of power transmission equipment, in particular to an intelligent transformer. Background technique [0002] Since 2000, driven by urban and rural power grid renovation projects, China's distribution transformer industry has maintained a good momentum of development. In 2008, the annual output of China's distribution transformers exceeded 400 million KVA, accounting for nearly 40% of the total annual output of transformers. In 2010, the output of China's transformers reached 1.223 billion KVA. Calculated according to the 40% ratio, it is estimated that the output of new distribution transformers in 2010 will reach 534 million KVA. In 2010, the distribution transformer manufacturing industry achieved an output value of about 42.518 billion yuan, a year-on-year increase of 18.84%. [0003] With the continuous deepening of China's "energy saving and consumption reduction" policy, the state encourages the devel...
