Description

Technical Field

[0001] The present disclosure relates to the technical field of switch health assessment, and in particular to a method and system for asset management and health assessment of switches throughout their life cycle. Background Art

[0002] In the past two years, many refusal to operate and malfunction accidents have occurred in power grid companies, which have attracted the grid company's high attention. From the current mechanical characteristics testing methods of switches, many potential problems are difficult to discover in advance, mainly because the mechanical characteristics data of the switch throughout its life cycle has not been effectively managed and analyzed.

[0003] At present, there are many types of testing instruments from various manufacturers, and the data formats and data transmission channels are different. The data of the entire life cycle of the equipment (including factory test, handover acceptance, pre-test and other data) cannot form a unified data format and storage channel. Secondly, most of the existing switch testing instruments only have the function of data monitoring, and lack effective means of evaluating the status of switch equipment. Basically, they rely on operators to obtain switch operation data through regular tests, and then evaluate the switch status based on experience. The evaluation results are greatly affected by the professional level, and the reliability is difficult to guarantee. It is difficult to meet the needs of smart grid construction for intelligent diagnosis of switch equipment status.

[0004] On the one hand, the traditional regular maintenance method is too costly, and on the other hand, some major hidden dangers are difficult to detect offline. With the continuous introduction of online status monitoring equipment and big data analysis technology for major electrical equipment, higher requirements are put forward for the way and method of power equipment status evaluation, which also brings major opportunities for the innovation of power equipment maintenance methods. Due to the complexity of the operating environment of electrical equipment, equipment failures are often caused by the superposition of internal and external factors. Once a problem occurs, there will be a chain effect. Therefore, fault diagnosis and maintenance should be based on active prevention and supplemented by passive maintenance.

[0005] In recent years, the expert fault diagnosis system based on the fault current fingerprint library of the opening and closing coils has attracted more and more attention. It comprehensively analyzes the working status of the switch operating mechanism based on the measured opening and closing current waveform, energy storage status, etc. Fingerprint analysis technology is used. When there is a significant change compared with the original fingerprint, it is regarded as a decrease in reliability or a defect. The self-assessment results are uploaded in the message format report of "unique identification, fault location, fault mode, and risk level (expressed as a percentage)", and a graphical alarm is displayed at the same time. Through a comprehensive comparative analysis of the switch opening and closing coil current curves, combined with the factory standard curves (obtained through mechanical property tests when the circuit breaker leaves the factory), the operating status of the switch is monitored and evaluated in real time, the changes and development trends of the mechanical status are judged, and a clear and intuitive health index is given;

[0006] Therefore, based on the above industry status and needs, the present disclosure proposes a switch full life cycle asset management and health analysis method for data standardization and unified analysis of switch mechanical characteristic tester data. Summary of the invention

[0062] Figure 3 The following is a flowchart of a method for asset management and health assessment throughout the life cycle provided by the present disclosure. Figure 3 As shown, the switch life cycle asset management and health assessment method is applied to the switch life cycle asset management and health assessment system, the switch life cycle asset management and health assessment system includes a management platform, a data standardization conversion module connected to the management platform, and a switch characteristic tester connected to the data standardization conversion module; the method includes the following steps:

[0063] Step 301: The management platform maintains basic information of the switch to be tested;

[0070] Step 302: the switch characteristic tester tests the mechanical characteristics of the switch to be tested, generates test data, and saves the test data as an intermediate model file;

[0071] In this step, upon arriving at the site, the mechanical characteristics test of the designated switch is performed using a switch mechanical characteristics tester. After each test is completed, the test data is saved in the specified data format (intermediate data model file) using the equipment's file management function. After completing multiple tests on a switch, multiple experimental data are saved (multiple data are saved in the intermediate data model file directory format).

[0073] Step 303: the data standardization conversion module obtains the intermediate model file, converts the intermediate model file into a standard model file, associates the standard model file with the basic information of the switch to be tested, and uploads the associated standard model file to the management platform;

[0074] In this step, the data standardization format conversion and communication module is used to establish a Bluetooth link with the mechanical property tester. After the Bluetooth connection is established, the switch test data is obtained through the module, or the data is obtained through USB. The data standardization conversion and communication module obtains data by selecting the data to be converted, and converts the standardized data (converting it into a standard data model file).

[0086] Step 804: The management platform generates a detection report of the switch to be tested according to the evaluation results of the health status and risk level of the switch to be tested.

[0087] In this step, before the data is stored in the database, it is initially judged by the data processing service. The data processing service integrates the switch fault diagnosis algorithm model and selects different analysis models to evaluate the health status of the equipment and the risk level. Combined with the maintenance decision model system, it can make intelligent decisions on maintenance and operation recommendations.
