Detailed Product Description

VCBI-24 indoor AC high-voltage vcb

General 
1) Mode VCBI-24 indoor AC high voltage vacuum circuit breaker (hereinafter as "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 enterprise and mine.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.

2) The circuit breaker features an integrated design to combine operating mechanism and circuit breaker itself into one. It could be used as a stationary installation unit or assembled or assembled into truck unit with some special driving mechanism.

Normal Application condition

1) Ambient Temperature:+40max,-15min.

2) Ambient humidity.

Daily average Rh measured within 24 hours ≤95% ,monthly average Rh ≤90%.

Daily average saturated vapor pressure measured within 24 hours ≤ 2.2kPa.

Monthly average saturated vapor pressure ≤ 1.8kPa.

Occasional dew could be found under such condition.

3) Altitude: ≤ 1000m.

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.
