Sub-health running status recognition method of electrical device

Abstract

The invention discloses a method for identifying the 'sub-healthy' operating condition of an electrical device, aiming at the problem that the prior electrical device does not have an intelligent real time monitoring means, so the maintenance of the device is realized through the regular check by people which is costly in terms of labor and materials; particularly the remote maintenance of the device through regular check is too costly. The method of the invention comprises the following steps of: monitoring the status of the electrical device by a data processing server, a data measuring terminal and the electrical device, with the data processing server memorizing the historical records of the collection capacities of all malfunction key points of the corresponding electrical device through a database software, and with the data measuring terminal carrying out long term real time monitoring over the malfunction key points of the electrical device and uploading the collection capacities of the malfunction key points to the data processing server through various communication means; judging if the present state of the electrical device is the malfunction critical state through a forecasting algorithm; and then reminding a user or a technician to repair the malfunction point in time. The method of the invention is suited to examining electrical devices.

Description

Technical field: [0001] The invention relates to an identification method for intelligent real-time monitoring of the operating state of an electrical device. Background technique: [0002] Traditional electrical installations do not have intelligent real-time monitoring methods. The maintenance of the installations is achieved through man-made periodic inspections. The use of man-made periodic inspections consumes manpower and material resources, especially the remote maintenance of the devices. The cost of regular inspections for such devices is very high. In addition, the method of repairing by technicians in the event of a failure also has disadvantages. Once the electrical device fails, it may cause huge losses. For example, the power generation device of a power plant is damaged and the shutdown is caused. Among the reasons for the failure of the electrical device, 90 % Is caused by damage to key electronic components. [0003] The so-called "sub-health" refers to the operat...

Problems solved by technology

[0002] Traditional electrical devices do not have intelligent real-time monitoring means, and the maintenance of the device is realized through artificial periodic inspection, which consumes a lot of manpower and material resources, especially the remote maintenance of the device. The cost of periodic inspection of this device is very high , In addition, the method of repairing by technicians when there is a failure also has disadvantages, that is, once the electrical device fails, it may cause huge losses. % is caused by damage to key electronic components

[0003] The so-called "sub-health" refers to the normal operation of the equipment on the surface, but there is a problem with one or more components, but the problem is not enough to cause the equipment to fail, but the parameters of the component with the problem at this time are running Changes have occurred, such as changes in the voltage drop of the PN junction, changes in the leakage current of a pin, etc. At this time, it is the "sub-healthy" operating state. The "sub-healthy" operating state is relatively hidden and difficult to be noticed by the user. However, if the equipment continues to work in the "sub-healthy" state, it will appear in an "unhealthy" state, that is, a failure will not only burn components and equipment, but also indirectly cause other economic losses and lead to serious consequences.
