Transformer impact monitoring device

Abstract

The invention discloses a transformer impact monitoring device, which relates to the field of transformer monitoring, and solves the problem that transformer impact monitoring and impact data recording cannot be accurately carried out in the prior art. The device comprises a signal conversion module for acquiring an analog signal output by a transformer PT / CT and isolating and converting the analog signal into a low-voltage analog signal; an input module used for acquiring a switching value signal of a circuit breaker in the transformer and carrying out optical coupling isolation and level conversion; an output module used for outputting four paths of relay empty node alarm signals to the outside; an acquisition module used for carrying out high-speed synchronous sampling on the low-voltage analog signal and the switching value signal, marking a timestamp accurate to microsecond on the sampled data, and outputting the acquired data in a network giant frame form; and a management module used for carrying out transformer impact event judgment according to the acquired data and carrying out impact data management according to a judgment result; wherein the signal conversion module, the input module and the output module are connected with the acquisition module, and the acquisition module is connected with 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...
