Storage, making and breaking by motor, It can operating by handle.
Breaking short-circuit current up to 25kA.
Mini motor spring mechanism (about 30W).
Installation method: adopt two type installation method.
Sealing performance: adopt reliable sealing technical.
Incoming & Outgoing method:adopt silicon bushing to make enough insulate distance
Safe operating: there is an equipment to protect explosion.
ZN85-40.S/T type indoor high voltage indoor vacuum circuit-breaker is used for switchgear KYN61-40.5(Z), it is most new type of power supply and distribution equipment. This product is accordance with GB1984-2003 stand. This series include: Vacuum circuit breaker truck, isolation truck and fuse truck.
Structural Characteristics:
1. This
vacuum circuit breaker adopts compound insulation; it can meet air distance and
creepage under normal run condition, and it effectively reduces the dimension
of VCB, the overall arrangement is reasonable and simple, with aesthetic
appearance.
2. The operating mechanism is especially newly designed for this VCB; the
outlet curve has good adaptation with requirements of vacuum interrupters. It
has high reliable with characteristics of long life and easy maintenance and
free-maintenance for operating mechanism.
3. This truck adopts screw rod nut push-in mechanism which can realize easy
pushing-in or pushing-out of panel; compulsive mechanical interlock way is
adopted; meet the Five Preventions function; suitable for varies site and the
working sites which have rigorous run condition
Ambient Conditions:
1.
Ambient temperature: -10℃–+40℃
2. Relative humidity: daily average 95.monthly average 90.
3. Earthquake intensity: 8 degree;
4. Saturated vapor pressure: the average pressure of a day should be no more than
2.2kPa; the average pressure of a month should be no more than 1.8Kpa;
5. The height above sea level:≤1000 m (Except special requirements)
6. Applicable occasions should free from inflammables, explosives, corrosives
and severe vibration.
