Abstract

The invention belongs to the technical field of power distribution, and particularly relates to a distribution transform terminal for power distribution automation. The distribution transform terminal comprises a main control unit, a distribution transform terminal body, a low-voltage reactive power compensation unit and a power source unit, wherein the distribution transform terminal body is connected with the low-voltage reactive power compensation unit; the low-voltage reactive power compensation unit is connected with the main control unit; the power source unit is connected with the main control, and comprises a 12 V power source and a 5 V power source; the main control unit comprises a chip U1; the pin 19 of the chip U1 is earthed; the emitting electrode of a triode Q2 is connected with one end of a resistor R1; the collecting electrode of the triode Q2 is connected with the 5 V power source; the other end of the resistor R1 is earthed. The distribution transform terminal has the advantages that a low-voltage reactive power compensation mode is adopted, so that the requirement for quick load changing can be met, reactive power compensation can be quick and dynamic, and power connection can be realized in a distributed manner. Therefore, a distribution transformer can operate more stably, and power supply can be more reliable and safer.

Description

technical field [0001] The invention belongs to the technical field of power distribution, and in particular relates to a distribution transformer terminal for power distribution automation. Background technique [0002] In the power supply and distribution system, the distribution transformer is the power equipment that directly distributes the voltage to the low-voltage users. Its operating data is an important part of the basic data of the entire distribution network, including: three-phase voltage, three-phase current, three-phase Phase active (reactive) power, power factor, frequency, oil temperature (humidity), etc. Whether these data are normal or not is an important reflection of whether the distribution transformer is running well. Therefore, real-time monitoring of abnormal conditions in the operation of distribution transformers and timely control or resolution can achieve stable and optimal operation of the power grid. However, in the traditional distribution sy...
