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.
