Abstract
The invention relates to a method for monitoring failures inside a transformer. The method for monitoring failures inside the transformer is characterized by comprising the steps that a first winding coil and a secondary winding coil of the transformer are respectively provided with a current transformer, and the output end of each current transformer is connected with the input end of a current collector; when failures occur in the winding coils of the transformer, data of the current collector change, so that failure occurring in a certain node inside the current transformers of the transformer is judged. The method can be used for monitoring the failures inside the transformer.
Description
Technical field
The present invention relates to a kind of power transformer interior fault supervision method.
Background technology
Breaking down in existing transformer inside, is difficult to effectively monitor.
Summary of the invention
The object of the present invention is to provide a kind of power transformer interior fault supervision method, the method can monitor power transformer interior fault.
To achieve these goals, the technical solution used in the present invention is: a kind of power transformer interior fault supervision method, it is characterized in that it comprises the steps: to be provided with respectively current transformer at primary winding coils and the Secondary Winding coil place of transformer, the output terminal of current transformer is connected with the input end of current collector by wire; When break down in the winding coil inside of transformer, there is data variation in current collector, thereby can judge that the inner a certain node of current transformer of transformer breaks down.
The primary winding coils place of described transformer is provided with 2-20 current transformer.
The Secondary Winding coil place of described transformer is provided with 2-20 current transformer.
The invention has the beneficial effects as follows: when break down in the winding coil inside of transformer, by current transformer, data variation appears in current collector, thereby can judge that the inner a certain node of winding coil of transformer breaks down.The method can monitor power transformer interior fault.
Accompanying drawing explanation
Fig. 1 is the structural representation that the present invention can monitor the transformer of internal fault.
In figure: the winding coil of 1-transformer, 2-current collector, 3-current transformer.
Embodiment
As shown in Figure 1, a kind of power transformer interior fault supervision method, it comprises the steps: that winding coil (being comprised of primary winding coils and Secondary Winding coil) 1 place at transformer is provided with current transformer 3, and the output terminal of current transformer 3 is connected with the input end of current collector 2 by wire; When break down in the winding coil inside of transformer, there is data variation in current collector, thereby can judge that the inner a certain node of current transformer of transformer breaks down.
The primary winding coils place of described transformer is provided with 2-20 current transformer (adopting 3 in Fig. 1).
The Secondary Winding coil place of described transformer is provided with 2-20 current transformer (adopting 3 in Fig. 1).
Realize the transformer of the monitored internal fault of said method, it comprises the primary winding coils of transformer and Secondary Winding coil, current collector 2, current transformer 3, the primary winding coils of transformer and Secondary Winding coil place are equipped with current transformer 3, and the output terminal of current transformer 3 is connected with the input end of current collector 2 by wire.
