PRODUCT PARAMETERS
ZW7-40.5 series outdoor high voltage vacuum circuit-breaker | ||||||||
Application
ZW7-40.5 series outdoor high voltage vacuum circuit-breaker is for three phase ,rated voltage 40.5KV,AC 50HZ power system., mainly used for breaking and closing load
current ,over current and short-current.
Main function
1.Using vacuum arcing, high breaking ability,long electrical endurance,mechanical life 10000 times.
2.Simple construction,maintenance-free,No maintenance cycle is long.
3.Good insulation performance,good prevent filth ability.
4.Can match the spring or electromagnetic operating mechanism,mechanically
sound,can be frequent operation.No fire and explosion risks
5.Built-in current transformer,accuracy of 0.2,can be realized three mutual protection
6.Built-in condensation controller, circuit breakers can be maintained at a certain
temperature reliably.
The use of environmental conditions
1.Ambient air temperature: Upper limit of +40,lower limit of -30.
2.Altitude: No more than altitude of 3000 meters.(If need higher altitude, its rated
level accordingly).
3.Wind pressure:Not more than 700Pa (amount to wind speed 34m/s).
