Outdoors Vacuum Circuit Breaker

Outdoor type Rated voltages 12/40.5KV

Main characteristicThis product mainly by the high-pressured petticoat insulators, the vacuum explosion chamber, the transmission system and holds the drive mechanism to be composed, may use for parts the electromagnetism or the spring holds the drive mechanism. It has breaks the performance finely, burns the arc time short, the electricity life long, the full capacity opens breaks 20 time does not overhaul, the insulation reliably, the structure is simple, the mechanical reliability higher merit.1st, uses the household outlook vacuum explosion chamber, has reliable, the life safely is long and so on the merit;2nd, uses the new insulation material, avoided the gasification, the sufficient oil and so on has been the result of the influence;3rd, the current transformer has the precision high, is changeable secondarier than and so on the characteristic;4th, may match the electromagnetism to hold moves or the spring holds moves two kind of organizations;5th, the circuit breaker has the level -like, center sets at outside the type, CT sets at the type three kind of structures.Using environment1st, altitude above sea level: <= 1000m (special request separate consults);2nd, ambient temperature: -30 °C ~ +40 °C (specially requests -40 °C);3rd, wind pressure:Does not surpass 700Pa (to be equal to wind speed 35m/S);4th, earthquake intensity:Does not surpass 8;5th, contamination rank:III level, IV level (crawls the electricity to compare the distance: 25mm/KV, 31.5mm/KV)6th, installs the place: Does not have the fire explosion hazard, does not have chemistry corrosion and the regular fierce vibration
