well-developed scientific research system
complete science and technology innovation platform
expanded technological innovation talent team
technology of developing high-end and intelligent switchgear
technical research capability: it has accumulated rich experience in basic technical research of switchgear and mastered key technologies such as analysis and testing of arc extinguish mechanism, electric field, airflow field and circuit breaker characteristic parameters. especially in terms of the operating mechanism of extra-high voltage and ultra-high voltage switchgear, the hydraulic operating mechanism with high power and reliability has been successfully developed; the serialization and modularization of the hydraulic mechanism have been fully realized; the comprehensive technical capability in the research of hydraulic systems has been improved. in the research of large insulation parts, the insulation pouring technology of ultra-high voltage, extra-high voltage and high voltage levels has been fully mastered.
results of simulation and analysis of airflow field, electric field and mechanics
equipment manufacturing capacity: it has the first-class domestic cnc machining center, shell welding production line, large electroplating production line of aluminum and copper parts, surface coating production line, imported epoxy pouring insulation parts production line and gis / gcb assembly production line, and has become a leading switch manufacturing base in china, laying a solid foundation for product development.
full series, full voltage grade switchgear: it has formed the national first-class and international advanced r&d technology of full series, ac / dc, full voltage grade series switches with fully independent intellectual property rights. it also took the lead in becoming the first switch manufacturer to develop 800 kv and 1100 kv gis, and the 1100 kv gis provided for uhv demonstration projects won the "2010 china power quality engineering award" and "2009 first prize for excellent engineering design in power industry" awarded by state grid corporation of china. lw6-550 circuit breaker won the national gold medal; the "circuit breaker with 220 kv and above" has been the famous brand in china; "pg" brand won the "china famous brand".
