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...

Examples

Embodiment 1

[0058] refer to Figure 1 to Figure 2 , the present embodiment provides a transformer shock monitoring device, which can be applied to monitor a single transformer or multiple transformers, and the device may include:

[0059] Signal conversion module, input module, output module, acquisition module, management module, wireless transmission module, human-machine interface module, and power supply module; the signal conversion module, the input module and the output module are all compatible with The acquisition module is connected, the wireless transmission module and the man-machine interface module are connected to the management module, and the acquisition module is connected to the management module.

[0060] Specifically, the signal conversion module is used to obtain the analog signal output by the PT / CT in the transformer, and convert the analog signal into a low-voltage analog signal through voltage transformer / current transformer isolation, and send it to the acquisit...
