Detailed Product Description
Features:
1) Mode VCBI-24 indoor AC high voltage vacuum circuit breaker is used as indoor
switchgear of 24kV power system and a control and protection unit in both
electric network equipment and power equipment in industrial enterprises and
mines
2) Owing to its unique advantages, the circuit breaker is especially applicable to
the frequent operation of rated working current or the operation with repeater
open and close of short circuit
3) The circuit breaker features an integrated design to combine operating
mechanism and circuit breaker itself into one
4) It could be used as a stationary installation unit or assembled or assembled
into truck unit with some special driving mechanism
Specifications:
1) Ambient temperature: -15oC ~ +40oC
2) Ambient humidity.
a) Daily average Rh measured within 24 hours: ≤95%, monthly average Rh:
≤90%
b) Daily average saturated vapor pressure measured within 24 hours:≤2.2kPa.
c) Monthly average saturated vapor pressure: ≤1.8kPa
d) Occasional dew could be found under such condition
3) Altitude: ≤1,000m
4) The ambient air is not obviously contaminated by dust, smoke, corrosive or
combustible gas, steam or salt fog
5) Any vibration outside the switchgear and control equipment as well as
earthquake could be negligible
6) The amplitude of induced magnetic interference in secondary system should
be less than 1.6kV
Features:
1) ZW8-12, ZW8-12G series high-voltage vacuum circuit breaker is a kind of
outdoor high-voltage switch equipment with 50Hz three-phase alternating
current and 12kV rated voltage
2) It is mainly applied to break and close the load current, overload and
short-circuit in country power net, city power net and mini type power system
3) The general framework of this product adopts the form of three-phase using
same box, i.e. put the three-phase arc-extinguishing chamber inside of the
metal box
4) For the SMG material has the advantage of space insulation and grounding
insulation, the breaker has perfect performance and high insulation strength
5) combination breaker
6) It can be used as sectional switch.
7) These series products have the operation framework of CT23 type power
storage with spring, which can be divided into electromotion type and manual
type
