Abstract

The invention discloses an energy-saving type power transformer fault instrument, and the instrument comprises a DSP mainboard, a power board, a transformer collection board, an installation bottom plate, and a liquid crystal plate. The installation bottom plate is fixed at the rear part of a case. The DSP mainboard, the power board and the transformer collection board are installed on the installation bottom plate, and are electrically connected with the installation bottom plate. The liquid crystal plate is disposed in a front panel of the case, and is electrically connected with the installation bottom plate through a data line. The DSP mainboard is electrically connected with the power board, the transformer collection board, the installation bottom plate and the liquid crystal plate. The transformer collection board is provided with an AC voltage and an AC current transformer circuit, and the AC voltage and an AC current transformer circuit is used for converting the AC voltage and AC current collected by the transformer collection board into a voltage and a current, which can be recognized by the DSP mainboard. The instrument is strong in anti-interference capability, and the DSP mainboard is provided with a DSP chip, thereby enabling the operation speed of a system to be higher. The instrument is more accurate in fault data, and is higher in precision.

Description

technical field [0001] The invention relates to a fault instrument, in particular to an energy-saving power transformer fault instrument. Background technique [0002] The abnormal operating conditions of power transformers mainly include: overcurrent caused by external phase-to-phase short circuit of the transformer and overcurrent and neutral point overvoltage caused by external grounding short circuit; overload caused by load exceeding the rated capacity. [0003] The power transformer is a very important power supply component in the power system, and its failure will have a serious impact on the reliability of power supply and the normal operation of the system. At the same time, large-capacity power transformers are also very expensive components. Therefore, it is necessary for distribution network automation system to monitor transformer faults. Contents of the invention [0004] Aiming at the above problems, the present invention provides an energy-saving power t...
