In the field of electrical engineering, in order to prevent equipment failures, the common inspection mode for power systems is "annual inspection (preventive testing)". Although the "annual inspection" combined with routine maintenance projects can detect some obvious equipment defects, in actual operation, accidents caused by equipment failures still occur every year in the power system.
ABB believes that the reasons for this are reflected in the following points: the lack of professional and targeted evaluation before maintenance, such as not considering the operating environment, service life, aging situation, industry specificity, not deeply investigating the explicit and implicit problems of on-site equipment, without reasonable contingency plans, and leaving hidden dangers; The testing items during maintenance are not comprehensive, such as the lack of vacuum degree testing and finger pressure testing, which leads to incomplete test results and hidden dangers that cannot be detected; For example, personnel lack professional skills, instruments and equipment are not regularly calibrated and measured, resulting in unreliable test data and affecting the judgment of equipment condition; If there is a lack of original factory solutions, it is impossible to solve the problems discovered during maintenance testing; After maintenance, there is a lack of subsequent risk interpretation and defect elimination follow-up plans, leaving many problems and unable to actively intervene in the declining reliability and operational efficiency of the equipment year by year. The effect on improving equipment reliability and effectively extending equipment service life is very limited.
What is ABB Electrical Worry Free Maintenance
ABB Electrical Services, with a century of experience and a nationwide service network, provides customized maintenance services through professional on-site assessments. ABB Electrical's worry free maintenance covers all medium and low voltage switchgear, using proprietary evaluation and diagnosis, providing customized preventive maintenance plans, analyzing equipment performance data, identifying potential faults, planning maintenance plans, ensuring good equipment operation, and guaranteeing business continuity and reliability.
Preliminary evaluation, ezReport ™ Series proprietary evaluation and diagnosis, more professional
ABB Navigate electrical service consultants will conduct a comprehensive and thorough understanding of the customer's on-site equipment based on complete ABB original production and manufacturing data, historical upgrade and renovation situations, and complete service records. They will use the ezReport series of proprietary evaluation and diagnostic tools to evaluate the on-site medium and low voltage live or power-off equipment. The evaluation content includes the risk index of the equipment, operation management regulations, operating environment, aging status, etc. It can identify fault characteristics early, comprehensively grasp the operating status of the equipment and the problems faced by customers, understand the operating risks of the equipment, make accurate judgments on the trend changes of the switchgear, and take timely measures in the subsequent maintenance process to prevent potential problems from occurring.
Mid term implementation, customized preventive maintenance plan, more thoughtful
Based on the risk level assessment results and combined with real-time and historical data support, ABB provides customized original factory maintenance solutions for users, including maintenance testing projects and replacement of high-risk internal components, in conjunction with the use of ABB proprietary instruments, to ensure efficient, comprehensive, and accurate maintenance work and improve the high reliability of electrical equipment.
● Targeted treatment: Based on the assessed risk level, customized maintenance and upkeep projects are provided
Be prepared: Provide customized spare parts list based on equipment operation status and service life
● Immediate results: Based on objective factors such as power outage plans/budgets, output customized preventive maintenance plans to solve
various problems on site
Follow up in the later stage, professional reports and maintenance plans, more comprehensive
ABB professional service personnel will generate customized maintenance summary reports based on on-site maintenance test records, inspection records, maintenance completion status, risk assessment status, displaying original factory summary reports comparing risk indices before and after maintenance, and providing suggestions for subsequent operation management and detailed maintenance plans if necessary. The maintenance summary report includes inspection results, testing reports, maintenance completion status, risk assessment results, etc. It informs users of the changes in risk index before and after equipment maintenance, and provides suggestions and measures to improve equipment reliability and safety from the perspective of operation management, as well as defect handling plans discovered during the maintenance process. At the same time, regularly follow up on relevant defect elimination plans and maintenance schedules to ensure reliable operation of equipment.
ABB's worry free maintenance service is committed to providing a high reliability and high safety operation and maintenance experience, reducing unexpected downtime, optimizing maintenance costs. Through worry free maintenance, we will enhance the reliability of your equipment and ensure its safe operation.
