Problems solved by technology

[0004] Nowadays, many transformers in the power system operate in complex environments. In this case, it is inevitable that the winding insulation paper in the transformer is damaged or corroded and becomes brittle, so it is very easy to cause a fire caused by the leakage of the transformer winding.

Embodiment Construction

[0010] The present invention will be further described below via accompanying drawing:

[0011] as attached figure 1 As shown, the winding leakage response method of the power system transformer first embeds the power system transformer winding circuit leak detector 1 and the ARM embedded processing chip 2 connected with it, and the power system transformer winding circuit leak detector 1 also contacts the power system transformer The outer side of the winding 3 and the leakage signal transmission switch 4, the power system transformer winding circuit leak detector 1 and the ARM embedded processing chip 2 are all in communication with the responsive buzzer 7. The electrical leakage signal transmission switch 4 is embedded with a primary buffer 5 for electrical leakage signals and a secondary buffer 6 for electrical leakage signals. If the winding of the power system transformer leaks, the power system transformer winding circuit leak detector 1 will collect the leakage signal...

Abstract

The invention provides a winding leakage response method of a transformer of an electric power system. If a winding of the transformer of the electric power system has electric leakage, a circuit leak finding instrument of the winding of the transformer of the electric power system collects an electric leakage signal at the outer side of the winding of the transformer of the electric power system in real time and sends the electric power system to an electric power system transmission switchover, so that the electric power system is transmitted to trigger a response type buzzer in an ARM (Advanced RISC Machine) embedded type processing chip for response. The problem that insulating paper of the winding in the transformer is easy to damage or becomes crisp due to erosion can be solved, so that the defect that the electric leakage of the winding of the transformer easily causes a fire can be overcome.

Description

technical field [0001] The invention relates to the field of electric power technology, in particular to a winding leakage response method of a power system transformer. Background technique [0002] The power system currently uses a large number of power system transformers, and the windings in the transformer are also the most important part of the transformer. [0003] One of the basic components. It is the circuit part of the transformer, usually wound with copper wire or aluminum wire wrapped in insulating paper. The winding connected to the high-voltage grid is a high-voltage winding, and the winding connected to the low-voltage grid is a low-voltage winding. Large power transformers use concentric windings. It sets the high and low voltage windings concentrically on the iron core column. Usually the low voltage winding is close to the core and the high voltage winding is on the outside. [0004] Nowadays, many transformers in the power system operate in complex e...
