Example 1
Fig. 1 is a flowchart of a method for predicting core rod embrittlement of an insulator, which is provided in an embodiment of the present invention, and the embodiment is applicable to performing disturbance correction and impact correction on a conventional embrittlement curve of a target insulator core rod, and determining a core rod embrittlement degree of the target insulator according to a correction result. As shown in fig. 1, the method includes:
s110, establishing a conventional crisping curve matched with the target insulator core rod according to a conventional environment core rod crisping model of the insulator and the type of the target insulator core rod.
It should be noted that the present invention is applicable to insulators having a core rod and an umbrella skirt structure, and may be generally referred to as composite insulators.
The conventional environmental core rod embrittlement model of the insulator is a pre-established model, the conventional environmental core rod embrittlement model of the insulator can output a conventional embrittlement curve of the insulator under the condition of not being disturbed or impacted, and the conventional embrittlement curve output by the conventional environmental core rod embrittlement model of the insulator can be different for different types of insulator core rods.
The types of the insulator core rods can be divided according to the conditions of materials, sizes and the like, when the novel insulator core rods which are not used before are used, only the conventional environment core rod shortbread model of the existing insulator is required to be trained according to the novel insulator core rods, and the insulator core rods have good reusability.
Alternatively, the conventional crisp curve may represent the process that the standard mechanical strength of the insulator core rod is attenuated with the increase of the service time, and it is further understood that the standard mechanical strength of the insulator core rod is gradually reduced with the increase of the service time of the insulator core rod, and the conventional crisp curve is generally a smooth curve.
S120, obtaining the disturbance type, the disturbance start time and the disturbance end time of each effective disturbance event of the target insulator before the current moment, and calculating to obtain the disturbance correction quantity of the core rod of the target insulator according to the disturbance model of the insulator.
Optionally, the type of disturbance event of the insulator may be classified into abnormal temperature, abnormal humidity, abnormal ph, abnormal stress load, abnormal salt density, and the like.
Optionally, the disturbance type, the disturbance start time and the disturbance end time of each effective disturbance event of the target insulator before the current moment can be monitored and summarized in real time through devices such as a sensor, and technicians can check through background records.
Further, an effective disturbance threshold and a disturbance effective time threshold may be set for each type of disturbance event, and when the event value of the disturbance event is greater than the effective disturbance threshold matched with the disturbance event and the continuous time of the disturbance event is greater than the disturbance effective time threshold, the disturbance event is taken as an effective disturbance event.
Table 1 is an alternative effective disturbance event definition table. Taking table 1 as an example, when the insulator lasts for more than 10 days and the temperature is greater than 40 degrees, the abnormal change of the temperature in the duration period can be regarded as an effective disturbance event; when the humidity of the insulator is greater than or equal to 70% for more than 30 days, the abnormal change of the humidity in the duration period can be regarded as an effective disturbance event; when the PH value of the insulator lasts for more than 15 days and is less than 5.6, the abnormal change of the PH value in the duration period can be regarded as an effective disturbance event; when the salt density of the insulator lasts for more than 10 days and is more than 0.2mg/cm 2 Abnormal changes in salt density over this duration may be considered an effective disturbance event; when the insulator has a stress load greater than 0.6 for more than 10 days, then the abnormal change in stress load over this duration can be considered an effective disturbance event.
The above description of the effective disturbance event is only used as an example, so that the present invention can be better understood, and the definition of the effective disturbance can be changed according to the actual requirement, for example, the judgment of the effective disturbance event can be performed only by depending on the event value of each disturbance event, and the effective disturbance threshold and the effective time threshold of each disturbance event can be changed according to the actual requirement, which is not limited herein.
The disturbance start time and the disturbance end time of the insulator can be obtained based on the service time of the insulator, for example, the start time of the abnormal temperature time is 1.5 years of the service time of the insulator, the end time is 1.6 years of the service time of the insulator, and the disturbance event of the insulator is generally sustainable, so that the disturbance start time and the disturbance end time of the disturbance event of the insulator are obtained, and the continuous time of the disturbance event of the insulator can be indirectly obtained.
The disturbance model of the insulator is a pre-established model, the disturbance model can comprise a plurality of sub-disturbance models, each sub-disturbance model can be matched with one type of disturbance event, after the disturbance start time and the disturbance end time of the disturbance event are input into the sub-disturbance model matched with the disturbance event, the disturbance correction quantity of the disturbance event can be output, and the disturbance correction quantity can be understood as the mechanical strength attenuation quantity of the insulator core rod under the disturbance event.
S130, obtaining the impact type, the action times and the impact time of each effective impact event of the target insulator before the current moment, and calculating to obtain the impact correction quantity of the core rod of the target insulator according to the impact model of the insulator.
Alternatively, the type of impact event of the insulator may be classified into a pollution flashover or partial discharge impact, a leakage current impact, a lightning strike current impact, and the like.
Optionally, the impact type, the action times and the impact time of each effective impact event of the target insulator before the current moment can be monitored and summarized in real time through devices such as a sensor, and a technician can check through background records.
Further, an effective impact threshold may be set for each type of impact event, and when the impact event has an event value greater than the effective impact threshold matched therewith, the impact event is taken as an effective impact event.
Table 2 is an alternative effective impact event definition table. Taking table 2 as an example, each impact event in table 2 may be an effective impact event as long as the primary event value is greater than the effective impact threshold. For example, when at least one flashover or partial discharge of the insulator occurs with a critical flashover current greater than 0.3, each flashover or partial discharge may be considered an effective impact event; when at least one leakage current of the insulator is larger than 50 mu A and the insulator is locally overheated, each current leakage can be regarded as an effective impact event; when at least one lightning strike event with the lightning withstand voltage of greater than or equal to 0.5 occurs in the insulator, each lightning strike event can be regarded as an effective impact event.
The above description of the effective impact event is merely used as an example, so that the present invention can be better understood, and the definition of the effective impact event can be adaptively changed according to the actual situation based on the above example. For example, multiple impact events of the same type having an event value greater than the effective impact threshold over a certain period of time may be regarded as one effective impact event, or the effective impact threshold of each impact event may be modified according to actual needs, which is not limited herein.
The impact time of the impact event of the insulator can be acquired by taking the service time of the insulator as a reference, the impact model is a pre-established model, the impact model can comprise a plurality of sub-impact models, each sub-impact model can be matched with one type of impact event, and after the impact event of each impact event is input into the sub-impact model matched with the impact event, the impact correction quantity of the impact event can be output.
Wherein each sub-impact model may include a mechanical strength loss model and a mechanical strength self-recovery model, and the impact modifier may include a mechanical strength attenuation value of the target insulator core rod caused by the impact event and a mechanical strength self-recovery value of the target insulator core rod after the impact event.
The invention considers that the impact caused by the same disturbance event or impact event to the insulator core rod can be different along with the mechanical strength attenuation of the insulator core rod, so the invention respectively considers the disturbance action time and the impact action time when calculating the disturbance correction quantity and the impact correction quantity. However, the action time of the disturbance event and the impact event can be not considered, and the event values of the disturbance event and the impact event can be used as the input of the insulator disturbance model and the insulator impact model so as to realize that the event value of the insulator disturbance event is used as the influence factor of the disturbance correction amount and the event value of the insulator impact event is used as the influence factor of the impact correction amount.
And S140, calculating to obtain the current mechanical strength of the target insulator core rod according to the conventional embrittlement curve, the disturbance correction amount and the impact correction amount of the target insulator core rod, and determining the core rod embrittlement degree of the target insulator according to the corresponding relation between the mechanical strength and the insulator core rod embrittlement degree.
It will be appreciated that conventional fringing curves, turbulence corrections, and impact corrections may all reflect changes in the mechanical strength of the target insulator core. The disturbance correction amount only includes the mechanical strength attenuation value of the target insulator core rod caused by each disturbance event, and the impact correction amount may include the mechanical strength self-recovery value of the target insulator core rod after the impact event in addition to the mechanical strength attenuation value of the target insulator core rod caused by each impact event. Therefore, the current mechanical strength value of the target insulator can be obtained by correcting the conventional embrittlement curve of the core rod of the target insulator through the disturbance correction amount and the impact correction amount.
In one specific example, the formula may be:
the current mechanical strength E of the target insulator core rod is calculated. Wherein E is A Represents the mechanical strength value of the target insulator core rod under the conventional crisp curve at the current moment,
representing disturbance eventsLoss value of mechanical strength after action of part i, Z i For the event value of disturbance event i +.>
For the duration of the disturbance event i +.>
A disturbance correction amount E after the action of all n disturbance events before the current moment Impact j Loss of mechanical strength after impact event j, E Self-recovery j Self-recovery value of mechanical strength after action for impact event j +.>
Impact correction amounts after the action for all m impact events before the current time.
Alternatively, the insulator core rod may be divided into high, medium, and low degrees of crispness, each degree of crispness being matched with a unique mechanical strength range of the insulator. For example, when the mechanical strength E of the insulator is 0.7 or more, the insulator core rod is low-degree crunched, when the mechanical strength E of the insulator is less than 0.7 and more than 0.5, the insulator core rod is medium-degree crunched, and when the mechanical strength E of the insulator is 0.5 or less, the insulator core rod is high-degree crunched.
Fig. 2 is a graph of an alternative insulator core rod embrittlement prediction. As shown in fig. 2, the vertical axis of the coordinate axis represents the mechanical strength E of the insulator core rod, and the horizontal axis of the coordinate axis represents the service time t, E of the insulator core rod A Represents the mechanical strength of the insulator core rod under the conventional shortenings curve,
the method is characterized in that the method represents the disturbance correction amount of the insulator core rod after a disturbance event, the drop value is the mechanical strength loss value after the impact event at the position of an irregular U-shaped curve pointed by the impact event, the rise value is the mechanical strength self-recovery value after the impact event, and the difference between the mechanical strength loss value and the mechanical strength self-recovery value is the impact correction amount after the impact event. The disturbance correction quantity and the impact correction quantity are utilized to correct the conventional crisp curve in real time, thus obtainingTo the real-time mechanical strength value of the insulator core rod.
According to the technical scheme, the conventional crisp curve matched with the target insulator core rod is established, the disturbance correction quantity and the impact correction quantity of the target insulator core rod are calculated, the current mechanical strength of the target insulator core rod is finally calculated, the core rod crisp degree of the target insulator is determined according to the mechanical strength, the influence of various abnormal conditions on the insulator core rod is fully considered, the crisp evolution of the insulator core rod can be evaluated on line, the service life of the insulator core rod can be evaluated in real time, the safe operation of the insulator can be guaranteed, and meanwhile resources are effectively saved.
