The project won by the State Grid Power Institute of Science and Technology, the main content includes the preparation of pilot provinces renewable energy development and smart grid construction of the technical route, the development of renewable energy grid technology standards, further in-depth study of wind power forecasting technology, upgrade wind power forecast System, as well as experience summaries and extensions of research results. This project is the first time that ADB will assist the construction and development of China's smart grid. It will help upgrade large-scale wind power and other intermittent renewable energy grid-connected operation technologies and accelerate the development of renewable energy in China.
Contact force impact on cold insulation terminal
In cold insulation terminal, the contact force is one of the basic elements.If there isn't enough contact pressure, with good conductive material is also of no help.Because, if the contact force is too low, will produce displacement between conductor and conducting strip, to produce oxide pollution, increased contact resistance caused by overheating.DRTB2.5 wire frame components, for example, only 0.8 Nm to screw torque, can produce up to 750 n actual contact force, and the size of the force had nothing to do with wire section.Therefore, the insulation terminal line pressing box has not subject to any environmental impact, large contact area, contact force of the permanent connection.Small contact voltage drop of the voltage drop size and identify socket one measure of quality.
In the moment, even for a screw with a small value of the voltage drop is still much lower than VDE0611 required limits.At the same time, applying the torque change in large scale, voltage drop is almost the same.Therefore, although different torque size used by operators, but does not affect the quality of connection.This is Insulated Terminals using another prove the reliability of the wire frame.
