Product introduction:
EVH4-15/T6300-80F Indoor high-voltage AC generator circuit breaker is a 15kV and below three-phase AC 50Hz vacuum generator output circuit breaker. When used in 12kV system, the applicable area can reach 5000m above sea level. It is mainly used in generators, phase regulators, pumped storage power station main circuits, small and medium-capacity power plant plant circuits and generator brake circuits.
Product features:
1. Large current, high breaking, high technical performance and process manufacturing level;
2. The system source short-circuit current DC component attenuation time constant is about 150ms, DC component 77%, transient recovery voltage rise rate: 4.0kV/μs; equipped with GLS type high-reliability spring mechanism "integrated integral operating mechanism"; rated current 6300A under natural air cooling when installed alone. The specially designed support insulator has an elliptical cross section, and its tensile and bending strength fully meet the design requirements. The support rod and the operating pull rod are made of high-strength vacuum impregnated materials. A voltage-grading ring with uniform electric field is designed between the insulator and the support. Fixed installation method, main circuit air insulation. The circuit breaker is installed at the bottom, which greatly improves the stability and convenience of installation.
