Vacuum Circuit Breaker

Hot sale 12KV Indoor ac high voltage three-phase vacuum circuit breaker Product Description If it becomes milky white from its original finish of silvery mirror then it indicates that the baffle is losing its vacuum. A sputter shield, usually, made of stainless steel, is placed between the contacts and the envelope in order to prevent the metal vapour reaching the envelope as it reduces the breakdown strength between the contacts. Inside the sputter shield the breaker has two

Hot sale 12KV Indoor ac high voltage three-phase vacuum circuit breaker Product Description A circuit breaker is a device that interrupts an electrical circuit to avoid unwanted currents, caused by a short circuit, which generally results from an overload. Its basic functionality is to interrupt the flow of current after a fault is detected. A vacuum circuit breaker is such kind of circuit breaker where the arc quenching takes place in vacuum. The technology is suitable for

Hot sale 12KV outdoor high voltage three-phase vacuum circuit breaker Product Description WORKING VACUUM CIRCUIT BREAKER When the fault occurs in the system, the contacts of the breaker are moved apart and hence the arc is developed between them. When the current carrying contacts are pulled apart, the temperature of their connecting parts is very high due to which ionization occurs. Due to the ionization, the contact space is filled with vapour of positive ions which is

high voltage 12KV vacuum circuit breaker VS1-12 withdraw type VCB ZN63 high voltage 12KV vacuum circuit breaker ZN63 VS1-12 fixed type VS1 indoor high-voltage alternating-current vacuum circuit breaker has a frequency of 50Hz and a rated voltage of 12kv. It applies to the electrical equipement control and protection in industrial and mining enterprises, power plants and substation, particularly to the places needing frequent operation. It can be fixed in a switch cabinet or

Hot sale 12KV outdoor high voltage three-phase vacuum circuit breaker Product Description During contact separation of circuit breaker arc is formed due to ionization of particles in the medium between the contacts. Idea behind the vacuum circuit breaker is to eliminate the medium between the contacts i.e., vacuum. Every medium that has a pressure below atmospheric, which is 760 mm of Hg, is known as vacuum. Low pressures are measured in torr, where 1 torr = 1 mm of Hg. The

Hot sale 12KV Indoor ac high voltage three-phase vacuum circuit breaker Product Description Vacuum circuit breaker has a high insulating medium for arc extinction as compared to the other circuit breaker. The pressure inside the vacuum interrupter is approximately 10-4 torrent and at this pressure, very few molecules are present in the interrupter. The vacuum circuit breaker has mainly two phenomenal properties. High insulating strength: In comparison to various other
