Urgent Need of Transformer in Smart Grid Construction -

Smart Grid & Mains Transformer Demand

The "Twelve Five" Period is the overall construction phase of smart grid. The next few years, the State Grid Corporation began the construction of three vertical and three horizontal structure connecting to the large energy base in China and the main electricity load center backbone UHV grid, which requires a large number of mains transformers, reactors, circuit breakers, GIS, power cables, high pressure casing and intelligent high-pressure equipment. Although manufacturers have begun to attach importance to and use of new sensor technology and intelligent components, but the safety and reliability of the transformer itself still has not been significantly improved. Therefore, it is necessary to improve the safety and reliability of the transformer body, strengthen the new materials, new technology, and new design, optimize the structure of the main longitudinal insulation, an appropriate increase in the insulation margin ofmains isolation transformer, design and actual values are matched, truly saves energy and environmental protection.

Transformer High-voltage Circuit Breaker

Currently, the transformer 220v to 12v high voltage circuit breaker structure is mainly pillar breaker tank circuit breakers, HGIS and GIS, its R & D is gradually tend to be reliable, functional integration, small footprint, low cost of the project direction. Transformer high-voltage circuit breakers are highly integrated functions, this need through integrated primary device functionality for small footprint, energy saving and environmental protection; synchronization control device by selecting the optimal operating time, to achieve the purpose of the limit, the transient current or voltage, reducing stress on the power system insulation equipment and a corresponding decrease in the controlled circuit breaker electrical wear.

Transformer Key Technology Research is Very Important

Transformer electronic transformer operating conditions are not satisfactory. Should strengthen key technology research, to carry out research for the electronic transformer manufacturing, application of key technologies and the design and process issues; should improve detection capabilities to meet the comprehensive quality testing needs of the growing number of electronic transformer, and further improve the technology standard norms of good governance. Intelligent online monitoring system, it is recommended to strengthen the online comprehensive monitoring system, operation, control and communication interconnect overhaul, maintenance planning, and data management to reduce the risk of equipment operation, and reduce operating costs. In addition, the sensor application research needs to consider the life of the sensor, to close with a body, take into account the influence of built-in sensor to the running of main device body, as well as the sensor distribution program.
