Transformer real-time monitoring circuit board

Abstract

The invention discloses a transformer real-time monitoring circuit board, comprising a CPU control unit, a DC / DC power supply circuit, a voltage-stabilized power supply circuit, a reference power supply circuit, a voltage detection circuit, a current detection circuit, a temperature detection circuit, a Profinet communication module, and a circuit substrate. The CPU control unit is disposed at theupper right corner of the circuit substrate. The DC / DC power supply circuit is disposed at the upper left corner of the circuit substrate. The voltage-stabilized circuit and the reference power supply circuit are respectively disposed at the upper middle positions of the circuit substrate. The temperature detection circuit, the voltage detection circuit, the current detection circuit, and the Profinet communication module are disposed in sequence from the left to the right side at the lower portion of the circuit substrate. The transformer real-time monitoring circuit board has a real-time monitoring program built in. The transformer real-time monitoring circuit board in the invention is small in size, low in cost, capable of real-time monitoring of key technical parameters of a transformer, high in detection accuracy, and suitable for protecting the absolute safety operation of transformers of a variety of models and specifications.

Description

technical field [0001] The invention relates to the field of transformer monitoring technical equipment, in particular to a transformer real-time monitoring circuit board. Background technique [0002] With the continuous development of industrial intelligent manufacturing and automation technology, transformers are used more and more widely, and it is the core part of welding automation equipment. Whether it works safely or not is directly related to the stable operation of welding equipment. In view of the importance of transformers in welding equipment, the effective protection of transformers is the focus of attention. [0003] In the prior art, because there is no real-time monitoring of the working state of the transformer, once the transformer breaks down, it will not work normally, and the consequences will be very serious. Contents of the invention [0004] In order to solve the above technical problems, the present invention provides a real-time monitoring circ...
