Product introduction:
EVH4-18/T5000-63F Indoor high-voltage AC generator circuit breaker is a vacuum generator output circuit breaker of 18kV and below three-phase AC 50Hz. 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 attenuation time constant of the DC component of the system source short-circuit current is about 150ms, the DC component is 78%, and the transient recovery voltage rise rate is 4.0kV/μs; equipped with GLS type high-reliability spring mechanism "integrated integral operating mechanism"; when installed alone, the rated current is 5000A under natural air cooling. Specially designed support insulator, elliptical cross section, tensile and bending strength fully meet the design requirements. Support rod and operating rod are made of high-strength vacuum impregnated material. A voltage-grading ring with uniform electric field is designed between the insulator and the support. Fixed installation method, main circuit air insulation.
