RDV6-12 seriesHigh voltage AC Vacuum Circuit Breaker is 3-phase A C12kV indoor switchdeviceis usually install at Middle type cabinet KY28 series,Box type substation and Armored type cabinet, as protector for industry,mine enterprise electrical equipment and the making and breaking circuit from load current,overload current and short-circuit protect current. And Because using Vacuum breaker, this product is speciallv suitable for the location of frequently operating under rated operate current,or open and break short-circuit many times.
Application：
RDV6-12 series high-voltage AC vacuum circuit breaker is a powerful three-phase AC12kV indoor switchgear, specially designed for the protection of electrical equipment in industrial and mining enterprises. The equipment can reliably realize the protection functions of open circuit, load current, overload current and short circuit protection current to ensure the safe operation of electrical equipment.
RDV6-12 series high-voltage AC vacuum circuit breaker has the following characteristics:
1. High-voltage protection capability: the circuit breaker is applicable to high-voltage protection under 12kV voltage level, and can effectively protect the equipment from the impact of high-voltage current.
2. Reliable protection function: the equipment can realize the protection function of open circuit, load current, overload current and short circuit protection current, to ensure that the equipment can cut off the current in time under abnormal conditions and protect the equipment from damage.
3. Frequent work and occasions with multiple circuit breakers and short circuits: the circuit breaker is suitable for frequent work under rated working current or occasions with multiple circuit breakers and short circuits to ensure the safe operation of the equipment under various conditions.
4. High reliability: RDV6-12 series high-voltage AC vacuum circuit breaker adopts reliable vacuum circuit breaker technology, which has high reliability, reduces equipment damage and failure, and extends the service life of the equipment.
5. Simple installation and maintenance: the equipment is easy to install and maintain, reduces the cost of equipment maintenance, and improves the operating efficiency of the equipment.
RDV6-12 series high voltage AC vacuum circuit breaker is a highly reliable and high-performance protection device, which can reliably protect electrical equipment from the impact of high voltage current and ensure the safe operation of equipment. It is widely used in industrial and mining enterprises and other fields requiring high voltage protection.

Basic function and characteristic：
1.Vacuum arc extinguishing chamber adopts Cu Cr contact material ,and Cup-shaped contactstructure of longitudinal magnetic field which has small wear rate, Stable dielectric strengthrapid recovery after arc extinguishing,low closure level, strong make and break strength,longelectrical life.
2.Between the insulation pole and the ceramic shell of the vacuum arc extinguishing chamber.Using fluid silicon rubber buffer,increase the impact withstand performance, An umbrellaskirt with a large climbing distance on the surface of the pole pillar, to improve the powerfrequency withstand voltage and lightning impulse withstand voltage, can meet the high-altitude area main technical requirement.
3.Operate mechanism is Spring energy storage mechanism of plane arrangement,has themanual storage and motor storage functions, to improve the stability of operation.
4.This circuit breaker operate mechanism, also adopted Permanent magnetic actuatormechanism,this mechanism reduces 60% components compares to the regular spring,reducesthe fault rate because of components.
