HCXH-12 intelligent suppressed arc cabinet is applied in 3~12kV three-phase non-directly grounding power system, which can fast extinguish the spasmodic grounding arc and eliminate the system resonance for the limited value of all kinds of over-voltage. It would limit the value for various over-voltage from non-directly grounding, system operation and atmosphere over-voltage.

Furthermore, it could accurately elect the grounding fault line of system and effectively improve the run security and the power

supply reliability of the above-mentioned system.

HCXH-12 intelligent suppressed arc cabinet can be widely applied to power plant, metallurgy, chemical, petroleum, coal, cement and other fields.
