Abstract

The invention discloses an intelligent transformer, belongs to the field of power grid transformers, and relates to the intelligent transformer. The intelligent transformer comprises an oil immersed transformer (1), a master station (2), a circuit breaker (3) and an intelligent terminal controller (4), wherein the master station (2) is connected with the circuit breaker (3) and the intelligent terminal controller (4) through a communication interface respectively; and the intelligent terminal controller (4) is connected with a mutual inductor group (5) for detecting the three-phase four-wire state of a power grid, a temperature sensor (8) for detecting an oil temperature of the transformer, a pressure sensor (9) for detecting an oil-gas pressure of the transformer, an electronic tap-changer (6) and a reactive compensation system (7) for adjusting the efficiency of the power grid and stabilizing a voltage, and a safety valve (10) for emergency processing. The master station (2) monitors and controls various indicators of the operation of the transformer through the circuit breaker (3) and the intelligent terminal controller (4) according to the detection information of the intelligent terminal controller (4), so as to make the power grid safe and stable. The intelligent transformer has high performance, high reliability and low cost.

Description

Technical field

[0001] The invention belongs to the field of power grid transformers and relates to an intelligent transformer. Background technique

[0002] The power grid has great volatility due to the complexity of the load, the failure of the grid itself, and the uncertainty of use. The fluctuation of the power grid not only affects the quality of power consumption of users, but also easily damages the equipment of the power grid itself. Therefore, in order to reduce the fluctuation of the power grid and its impact, many substations have adopted smart transformers. Smart transformers can not only detect various indicators of the power grid, such as three-phase phase voltage, three-phase phase current, zero sequence voltage, zero sequence current, frequency, harmonic content, active power, reactive power, power factor, active energy, and no Parameters such as power and energy can also detect its own conditions, such as transformer oil temperature, oil pressure, etc. At the ...
