s101: and receiving first operation monitoring data collected by the data collection cluster at the intelligent cable.
In the step, basic data of intelligent cable operation are mainly collected, and then the data are further identified and processed to confirm the fault condition. When the intelligent cable breaks down, various corresponding monitoring data at the intelligent cable are changed. For example, common faults of cable lines include mechanical damage, insulation moisture, insulation aging deterioration, overvoltage, cable overheating fault and the like. When the fault occurs, the temperature data, the current data and the vibration data nearby the fault can be known to be correspondingly transformed; by identifying the data, the corresponding failure condition can be confirmed.

Because when adopting partial discharge monitoring module to carry out data monitoring, receive environmental noise to its influence easily, in order to further carry out noise filtering interference to the data that obtains, adopted the shielding module to carry out the shielding of data in this application embodiment and handled, and then filtering environmental noise is right the interference of the partial discharge signal of the monitoring of partial discharge monitoring module improves the accuracy of data monitoring.
S102: and converting the first operation monitoring data into a digital signal to obtain second operation monitoring data.
The step is mainly to convert the data of the analog signal part in the first operation monitoring data into a corresponding digital signal for subsequent transmission and data processing. Besides the conversion of digital signals, the data can be uniformly processed and marked according to a certain rule, so that the input of the data into the recognition model is facilitated.
S103: transmitting the second operation monitoring data to an input end of a preset fault recognition model, and obtaining corresponding fault data at an output end of the fault recognition model; and the fault identification model is constructed by adopting a neural network model.
And inputting the processed operation monitoring data into a preset fault recognition model for recognition processing so as to determine which fault the corresponding fault belongs to. The fault identification model in the embodiment of the application adopts a neural network model to construct data.
More preferably, the neural network model includes any one of a BP neural network model, a radial basis function neural network model, or a convolutional neural network model.
Specifically, fig. 3 is a schematic flow chart of the fault analysis model construction provided in the embodiment of the present application, and as shown in fig. 3, the fault identification model is constructed through the following steps:
s103 a: obtaining marked historical monitoring data;
s103 b: collecting the obtained marked historical monitoring data to generate a corresponding monitoring training set;
s103 c: and constructing a fault recognition model based on the convolutional neural network, and recognizing and training the fault recognition model by taking the monitoring training set as input and the fault data as output until the training requirements are met.
In the above mode of adopting the convolutional neural network to construct the model, when data is constructed, the obtained historical monitoring data needs to be marked, the historical monitoring data is the data monitored when a fault occurs, various monitoring index data are obtained, then fault confirmation marking is carried out manually, and after the marking is completed, a corresponding training set is generated in a combined manner; and then, in the neural network model, the fault recognition model is recognized and trained by taking the monitoring training set as input and the fault data as output until the training requirement is met. And when the identification accuracy reaches the set target, determining that the corresponding fault identification model can be put into use when meeting the standard requirement.
In addition to the convolutional neural network model for constructing the fault analysis model, in the embodiment of the present application, a BP neural network model may be used for constructing the analysis model.
Specifically, fig. 5 is a schematic diagram of an architecture of a BP neural network model provided in an embodiment of the present application, and as shown in fig. 5, in a modeling process of the BP neural network model, a data sample, that is, input/output sample data of a system, is loaded first, then a 3-layer forward neural network is created, a weight and a threshold of the model are trained by using a training sample, the trained model is tested, and an output of the model is compared with a detection value of the system to check accuracy of the model. Because the initial weight coefficient is a small random nonzero value, and the convergence rate of the BP algorithm is related to the selection of the initial weight, a good training result can be obtained by training the neural network for multiple times.
Specifically, in the present embodiment, classification of the resistance pattern of the fault point is implemented for the measured values of the 5 detection point potentials, and a neural network is used as a classifier for the relationship between the detection point potentials and the resistance pattern of the fault point. The neural network classifier has a structure that three layers of BP neural networks input 5 rows and 6 columns of vectors, an output layer is a 2-dimensional output vector, and corresponding fault modes are divided into three types, namely single-phase metallic ground fault, two-phase ground fault and three-phase ground fault. The relation between the detection value and the fault type is found through continuous learning and training of the neural network model, and then corresponding model construction is completed, so that when fault identification is carried out subsequently, the corresponding fault type can be determined directly through identifying corresponding data.
S104: and transmitting the fault data to a data matching module to perform data matching with a pre-stored fault strategy model so as to obtain a corresponding fault solution strategy.
This step is mainly to confirm the matching problem between the specific fault type and the fault resolution strategy, because even if the corresponding fault type is identified, if the corresponding resolution strategy is not provided, the maintenance management of the manager is not convenient, and the auxiliary function is not obvious enough.
Some faults and corresponding measures for handling the faults are listed in the embodiment of the application, but the specific implementation is not limited to the following ways:
1. cable line ground fault and handling measures: the underground moving soil is damaged, the insulation is damaged, the ground can be dug, and the insulation can be repaired; the artificial grounding is not removed, and the grounding wire needs to be removed; the load is too large, the temperature is too high, the insulation is aged, the load is adjusted, the temperature is reduced, the aged insulation is replaced, and some cables which are seriously aged are replaced; the sleeve is dirty, and discharge is generated due to cracks, and the dirty sleeve needs to be cleaned and replaced by the cracked sleeve.
2. Cable short circuit burn-out fault and treatment measure; the cause of the short-circuit failure may be as follows: the cable selection is unscientific, the thermal stability is not enough, the insulation damage occurs, the short circuit is cracked, the cable load is reduced after the repair is needed, and the line continues to operate; the multiphase grounding or grounding wire and the short circuit wire are not removed, the grounding point needs to be found out, and the fault or grounding wire and the short circuit wire are removed; aging of interphase insulation and mechanical damage; the cable head joint is not hard up, overheated, and the ground connection collapses to burn, and the cable head joint of will fastening is avoided becoming flexible.
3. Cable interphase insulation breakdown short circuit or relative ground insulation breakdown fault and treatment measures: the cable itself is mechanically damaged to cause insulation damage; when the insulation is affected with moisture due to various reasons, the insulation strength is reduced and the insulation is broken down; cable insulation aging; the corrosion of the protective layer and the lead ladle causes the damage of the insulating layer to be punctured; breakdown is caused by overvoltage; the cable has too high operating temperature, which causes insulation breakdown and breakdown. After a failure, the battery is reconnected or replaced with a new one.
4. Inter-phase insulation breakdown or phase-to-ground insulation breakdown of the intermediate joint to ground short circuit fault and treatment measures: the intermediate junction box has defects, such as loose connection of all parts when assembled, insulation damp breakdown caused by moisture immersion due to poor sealing after washing and filling of the insulating agent, and qualified intermediate junction boxes and reworked intermediate joints need to be selected and made. The lead connecting joint is in poor contact, and the insulation breakdown is caused by local heating, so that the heating reason is found out and corresponding measures are taken. The wiring has sand holes or cracks, so that moisture and humidity enter the box, insulation is damped and punctured, defects need to be eliminated, and the quality of the wiring box is improved. The middle joint is not properly manufactured, for example, the wire core and the joint are not uniformly connected, and the local insulation reduces the breakdown; the cable glue is poured unevenly, and the dielectric medium is dissociated under the action of an electric field, so that the insulation is damaged and broken down. The intermediate joint manufacturing process is to be observed. The breakdown caused by poor insulating material is to configure and select the insulating material with good quality.

The method for preventing the secondary fault of the cable caused by the overvoltage comprises the following steps: different types of faults can often occur to the cable due to overload, poor management and the like, and the occurrence of the faults often causes overvoltage to cause secondary faults of the cable. The breakdown of the cable middle joint caused by the cable ground fault, the cable breakdown caused by the three-phase interphase short circuit of the line and the like. In the event of a single-phase metallic ground fault, the non-fault phase-to-ground voltage may rise to three times the rated voltage, and through the fault to the arc resistance ground, intermittent arcs of arc extinction and re-ignition may occur. These fault conditions can cause the circuit to resonate, produce the overvoltage in fault phase and non-fault phase, the time that this overvoltage lasts is usually crossed, the danger of overvoltage is also very big, it can accelerate the cable insulation aging, break down the cable in some insulating weak links. This phenomenon occurs more in cables insulated with impregnated paper. In order to avoid the secondary fault of the cable caused by overvoltage, the following methods are adopted: mechanical damage to the cable is reduced as much as possible during cable erection and construction; carrying out a voltage withstand test on the cable regularly to eliminate hidden dangers; the manufacturing quality of the cable terminal and the intermediate joint is improved.
