Research On Quality Management Of Medium Voltage Switchgear In

Along with the enlarging of power grid construction and due to the seriousness of the fault and damage of electrical equipment, State Grid Corporation of China (SGCC) began to choose the enterprises for electrical equipment after strict appraise and elect. SGCC also standardized the technical requirements, their purchasing procedure and implement the policy of Concentrated Bidding Inviting on electrical equipment gradually. And SGCC will increase the responsibility investigation on the fault and damage caused by electrical equipment and will inflict punishment on the relevant enterprises. All of these promote the subcontractors to enhance their own competitive capacity and assure the product quality and the after-sales service. Therefore, the researching on quality management of electrical equipment enterprises is important and necessary.As a kind of electrical equipment, medium-voltage switchgears have something in common with other electrical equipment in quality management, especially in the establishing of enterprise quality system. However, there are also a lot of difference, such as technical requirement, manufacturing process and after-sales service. There are some researching on quality management of electrical equipment enterprise, but most of them study from the establishing of enterprise quality system. The researching on quality management of is little and in primary stage at present. Using the Principle of Total Quality Management and the product quality management from ’before production’,’in production’and’after production’, this dissertation breaks down the quality features of medium-voltage switchgears, and introduces the detailed proposal from’standard design on switchgear’,’production line management’,’incoming quality control’and’inspection procedure’by analyzing IEC/GB Standard on Medium-voltage Switchgear and relevant SGCC’s Technical Specifications. This dissertation also introduces some theory and methods to establish the enterprise quality culture of Medium-voltage Switchgears Company.At the end of this dissertation, it summaries the result after X Company implements the Total Quality Management. It also makes an example for the whole medium-voltage switchgear industry.
