Electrical industry, the rapid development driven by industries upstream and downstream enterprises rapid development of high-voltage switchgear as an important part of the electrical equipment, plays the role of control and protection in the transmission and distribution system, as China's power grid construction accelerated, high-voltage switch industry ushered in a good development opportunities, but the electrical industry in 2011 suffered a widespread "winter", "winter" under the influence of the high-voltage switch industry is some what scene?

Significant achievements

Voltage switchgear industry in 2011 with the speedup of the power grid construction, basic development situation has not been the impact of the "winter" of the electrical industry, this year the process of development of the industry, although they are still a problem, but the policy as well as the introduction of standards for high-voltage switchgear have a considerable impact in the industry, through independent innovation, high-voltage switch industry also received progress.

First point of view, the State Grid Corporation in March last year, held in Beijing, strong and smart grid construction results news conference, developed 15 smart substation standards formed the world's first intelligent substation series of technical standards, industry standards, this standard formulated largely shows the construction of smart grid applications have achieved success, intelligent direction expected for high-voltage switch industry is a step closer.

Undergone more than four years, GB/T11022-2011 "high-voltage switchgear and control equipment standard shared technical requirements" officially released on December 30, the standard is mainly to solve the common requirements for high-voltage switchgear and control equipment standards, and shared test procedures and requirements, such as insulation test, temperature rise test, short-time withstand current and peak withstand current test.

The Second grid building, in May last year, the General Office of the State Council issued a formal notice "on the implementation of the new round of rural power grids upgrade project views, the State Grid Corporation arrangements in the" 12th Five-Year "period, not the transformation of rural power comprehensive reform, not suited to problem solve upgrading power grids, the target to companies operating in the region within the rural power supply reliability rate of 99.7% in 2015, the integrated voltage qualification rate reached 98.5%, the consolidated line loss rate of 6.2% on average, The new round of rural power grids for high voltage switch industry is a good opportunity for development.
