Abstract

The invention discloses a transformer shock monitoring device, which relates to the field of transformer monitoring and solves the problem that the prior art cannot accurately monitor and record shock data of transformers, including: obtaining analog signals output by transformer PT / CT, and isolating and converting them It is a signal conversion module for low-voltage analog signals; an input module that obtains the switching signal of the circuit breaker in the transformer, and performs optocoupler isolation and level conversion; an output module that provides external output of four-way relay empty node alarm signals; The high-speed synchronous sampling of voltage analog signals and switching signals, the sampling data is stamped with time stamps accurate to microseconds, and the acquisition module outputs the collected data in the form of network giant frames; and is used to judge transformer impact events based on the collected data, A management module that manages impact data according to the judgment result; wherein, the signal conversion module, input module and output module are connected to the acquisition module, and the acquisition module is connected to the management module.

Description

technical field [0001] The invention relates to the technical field of transformer monitoring, in particular to a transformer shock monitoring device. Background technique [0002] With the continuous advancement of science and technology, while electricity has brought huge power and benefits to the development of human society and economy, modern production and life are increasingly dependent on electricity. This makes the power system failure, especially when a large-scale blackout occurs, will cause extremely catastrophic consequences. Therefore, since the power system appeared, how to ensure its safe and stable operation has become an eternal subject of power workers' research. [0003] The power transformer is one of the most core and widely used hub equipment for energy transmission and conversion in the power grid. Its performance is closely related to the safety and reliability of the power system. The reliable operation of its equipment is crucial to the stable ope...
