Example Embodiment

[0033] Example 1

[0034] Refer figure 1 , An embodiment of the present invention, there is provided a method for warning the user intelligent detection transformer, comprising:

[0035] S1: collecting operating parameters of the transformer and pretreatment; should be noted that:

[0036] Transformer operating parameters include temperature, humidity, current, voltage;

[0037] Further, the operating parameters of the transformer preprocessing comprises:

[0038] Data cleaning, data transform, and number set of data collected;

[0039] Data isolation of data after extensive collection is converted to a digital signal;

[0040] Normalization processing a digital signal obtained as characteristic data sets:

[0041] Y∈ {x *, y *, i *, u *}

[0042] Where x * represents the temperature value, Y * indicates the humidity ratio, i * represents the current value, u * represents the voltage value.

[0043] S2: The pre-processed data with a preset standard data for comparison; specific:

Example Embodiment

[0069] Example 2

[0070] Another embodiment of the invention Example of the present embodiment, this embodiment is different from the first embodiment is to provide a method of verification test warning A user intelligent detection transformer, to be verified as described in the technical effect of the method employed, Example for comparison testing of the present embodiment of the invention using conventional methods and technical solutions, means to compare the test results of scientific proof to verify the method has a real effect.

[0071] Conventional solutions: monitoring a single detection information, and most of the time required to detect artificially low degree of automation, accuracy and low efficiency, high cost, resulting in low security and reliability of electrical equipment. This method is relatively conventional verification method has high detection accuracy and efficiency. Embodiment of the present embodiment will be respectively identified fault detection and...

Abstract

The invention discloses an intelligent detection and early warning method for a user transformer. The method comprises the steps of collecting and preprocessing operation parameters of the transformer; comparing the preprocessed data with preset standard data; if the data value does not meet the preset standard data value, distinguishing prompt is carried out, early warning information is sent to a terminal, and the terminal carries out adjustment according to the early warning information and continuously carries out data comparison; and when the adjustment time exceeds the preset time and the digital signal does not meet the standard data preset value, starting an active control system to control the fault operation transformer to stop operating. Omnibearing monitoring of operation of the transformer and improvement of operation conditions of the transformer by auxiliary equipment are realized, electric energy loss of the transformer and a circuit is reduced, output reduction of the distribution transformer and large zero-sequence current generated by the distribution transformer are avoided, safe operation of electric equipment is guaranteed, electric power resources are utilized to the maximum extent, and the requirement of electric equipment on the power quality is met.

Description

technical field [0001] The invention relates to the technical field of electric power, in particular to an intelligent detection and early warning method for user transformers. Background technique [0002] The temperature and humidity device can monitor the temperature and humidity of the equipment environment, and can start the auxiliary equipment for temperature and humidity processing; the current transformer and voltage transformer can convert large current and high voltage into small current and low voltage to achieve the purpose of safety isolation , to ensure the safety and reliability of personnel when measuring large current and high voltage, and at the same time meet the needs of secondary equipment electronic products; the signal processor can process the collected information and visually present the equipment situation through the screen display. However, the existing monitoring system is not comprehensive, and the monitoring information is single. It only moni...
