Study on the Reliability of Residual Current Protection of CM2L MCCB
Residual current circuit breaker(viz. moulded case circuit breaker with residual current protection) is a type of new low-voltage safe protection device, it can offer not only overload and short circuit protection but also avoid the electric shock and fire accident.The study on the reliability of residual current circuit breaker is very important for improving the [...]
Passegner Cars Roof Ditch Molding Free Proposal Implementation Process Study
In the earlier auto design stage, it was requiring a long period and a step-by-step course. Normally, new process design was not concurrent to the new product development, and launched in the existing products, and then the vehicle properties was built after the design completely finished. This method reduced the high launch failure risk, but [...]

Quality of product is life of the company,the executives of the company have recognized the importance of quality and taken all kinds of measures or methods to ensure it. FMEA is increasingly being adopted by our many scale-enterprises, implemented and in-depth studied, it have achieved certain results. At the same time, we must also be [...]
Research on the Application of Reliability Centered Mainteance in Decision Support System of Marine Eequipment
At present, time-based maintenance is used in China’s Marine equipment maintenance, and which based on the fixed period of maintenance mode have made considerable contribution for the normal operation of equipment. However, with the increasing of marine equipment structure complication, regular maintenance can’t meet the requirement of the new situation. The reason is the failure [...]
The Reliability Evaluation of Large-scale Power Supply System and Voltage Sag Based on the Analytical Method
Because of increasing scale and complexity of electrical system power supply network, new requirements for service ability of electrical system are put forward. Over the past few decades, on the topic of service ability of electrical system analysis the research on power generation and transmission system reliability is attached importance and service ability is neglect, [...]
Research on Application of RCM Theory in Transformer Condition Assessment
Power transformer is the core of energy conversion and transmission in the power grid, the operating reliability of transformer has deep influences on security and stability of power systems. In this paper, according to the theory of Reliability centered maintenance (RCM), using the method of Failure mode and effect analyzes (FMEA), the main fault modes, [...]
Grey Correlation Risk Evaluation Method of Converter Transformer
Converter transformer is the key equipment in ultra hvdc transmission system, but also the core equipment connecting the converter station and the inverter station in AC and DC transmission systems. Therefore, the risk evaluation of converter transformer is very significant to the success for the condition-based maintenance, which is performed timely and accurately. Because it [...]
